6m JT65

At the moment I am not on 10m WSPR, but I am on 6m JT65. So far, just G stations and no Es on 6m seen here. Of course, it is still early and things could well change.

UPDATE 0934z: 6m JT65 spots of me from Serbia and Romania, which look like Es.

UPDATE 1235z: EA9IB in Ceuta and Melilla, N. Africa (1907km) spotted on 6m JT65.

UPDATE 1514z: Mostly EU Es spots on 6m today, apart from EA9 (N.Africa) earlier. Iceland counts as Europe.

Burwell Museum and Windmill - NOT amateur radio

Our local windmill and museum (right next door!) is one of the very best local museums in the whole of the UK. It is open 11am-5pm every Thursday, Sunday and Bank Holiday from Easter until late October. It is huge and is spread over many buildings. It goes on and on! When my grandchildren can't go they cry. For a few hours out, it is well worth a visit if you are in the area.

See http://www.burwellmuseum.org.uk/ .

Sunspots and 10m - Sunday June 25th 2017

Solar flux is little changed at 74 today. Sunspot number is 28. A=9 and K=2.

24 Jun 2017

Windmill in summer - NOT amateur radio

This is the view up the lane to "our" 200 year old windmill. On the left is an ornamental cherry tree.

6m JT65

So far today on 6m JT65 transceive, there has been a lot of Es across Europe, but nothing further apart from EA8DRM (3015km) in the Canary Is.

UPDATE 1948z: AA4V (6544km) in South Carolina was spotted. Judging by other spots, I am pretty sure this is genuine.

Convolvulus - NOT amateur radio

This is often known as bind weed. In the garden it is a nuisance, but it has nice flowers and looks good in the wild as here.

Need for 472kHz antenna improvements

Although these days I am very dependent on help with antenna work because of my stroke, I very much hope I can try a better antenna on 472kHz WSPR this autumn and winter. I have been surprised how well the earth-electrode "antenna" works, but another 10dB ERP would be really worth trying. I have in mind a long-wire, which needs a support at the end of the bungalow. I also need a better earth system.

My homebrew transverter for 472kHz puts out about 12W. With a better antenna an ERP around 50-100mW should be possible. At the moment, my 472kHz ERP is around 5mW.

See https://sites.google.com/site/g3xbmqrp3/mflf/472wspr

Low storm risk

It is very unlikely my amateur radio activities will be interrupted by storms today. The nearest storms are way to the south. This morning we have had a few dark skies, but no rain.

See https://www.lightningmaps.org/?lang=en#y=53.2284;x=-7.0347;z=4;t=3;m=sat;r=0;s=0;o=0;b=0.00;n=0;d=2;dl=2;dc=0;

Virtual Amateur Radio

I have to confess, I have not tried "virtual" ham radio for many years. It is a poor substitute for the real thing. Even with my poor voice these days, the real thing offers so much more. Nonetheless, it will appeal to some, especially when HF conditions are poor.  I expect this will become more popular in the next few years. As it name implies, virtual ham radio uses the internet rather than the ionosphere as the medium of "propagation". If all you want is to chat, this may be for you.

Sunspots and 10m - Saturday June 24th 2017

Solar flux is 73 again today. Sunspot number is 22. A=5 and K=1. I am not currently on 10m, but there is Es already on 6m.

Rally this Sunday

25 JUNE 2017 : WEST OF ENGLAND RADIO RALLY

Cheese & Grain venue, Market Yard, Bridge Street, Frome, Somerset BA11 1BE. Doors open from 10am to 2pm with admission priced at £3 for adults and children under 14 free. There will be inside & outside traders, free car parking, cafe, RSGB bookstall, accessible & facilities for disabled. Details from Shaun, G8VPG on 01225 873 098 www.westrally.org.uk

A list of rallies can be found at http://rsgb.org/main/news/rallies/

23 Jun 2017

Low storm risk in the UK

With the nearest storms being in Austria, I think I can safely "play radios" today.
 Just I case, I'll keep and eye on the maps.

See https://www.lightningmaps.org/?lang=en#y=53.2284;x=-3.9585;z=5;t=3;m=sat;r=0;s=0;o=0;b=0.00;n=0;d=2;dl=2;dc=0;

Where I was born - NOT amateur radio

The picture shows where I was born in Devon, UK when a nursing home after WW2. The film "Sense and Sensibility" was, in part, filmed on the Flete estate. This is Flete House. These days they are posh retirement flats.

Not much Es on 6m JT65 yet

I have been on 6m JT65 for some time. No Es seen yet today on 6m, although I am supposed to have spotted a station in Indonesia on 6m, which I do not believe. This suggests the pirate is in the UK. Sad.

UPDATE 1045z: Some Es with my 1W ERP 6m JT65 being spotted in Finland.

Sunspots and 10m - Friday June 23rd 2017

Solar flux is 74 today and the sunspot number 23. A=6 and K=1. 10m? Expect Es but F layer N-S is more doubtful on 10m.

ICOM IC703

Until I sold mine to a local fellow ham several years ago, I used this rig most days. They are hard to find now, and I am not surprised. In many ways I regret selling mine, but it went to good home and is well used.

Sadly, there is no real equivalent QRP rig outside of Japan. The IC7300 is probably the nearest, modern rig, but the 10W version is only available in Japan. If the 10W version was available in the UK, I would buy one, as I suspect would many.

The IC703 is a 10W 160m-6m multi-mode transceiver with an auto-ATU. It has a good DSP filter. Altogether a good, solid radio.

See https://sites.google.com/site/g3xbmqrp3/hf/ic703

22 Jun 2017

VLF transmitters

Recently I had an email asking me if stereo amps (100W) would make a suitable VLF TX. The short answer is "yes", although these are designed for a low impedance load, so would require a suitable matching transformer. I have not tried one.

Storm gone, so back on 6m JT65

The storm has passed through, so I have returned to 6m JT65 transceive (1W ERP). I tried replying to a few CQ calls, without success, so I am currently in beacon mode sending "B G3XBM JO02". Best report is from CT2IWW (1382km). There seems less Es about at the moment.

UPDATE 2038z: As well as spots of OX3LX (2570km) which I do believe, I also (supposedly) spotted another Indonesian station, which I do not believe: I am convinced this is a pirate somewhere in Europe. Unless proved otherwise, I am dismissing these latter spots.

Storms, so QRT

Although the weather forecast showed no risk, there is thunder close by, so I have disconnected antennas and power and gone QRT. I have found the weather forecasts very poor.

See https://www.lightningmaps.org/?lang=en#y=52.5523;x=-0.4813;z=7;t=3;m=sat;r=0;s=0;o=0;b=0.00;n=0;d=2;dl=2;dc=0;

UPDATE 0852z: The forecast says less than 5% of rain. Guess what? It has just rained!

Youngsters and amateur radio

This is a point I have made many times: unless we attract young people into our hobby and keep their interest, it will die with us. I see on Southgate News that the ARRL has been doing something about the growing crisis.

See http://southgatearc.org/news/2017/june/amateur-radio-needs-young-people.htm#.WUuA4LpFzmQ

Sunspots and 10m - Thursday June 22nd 2017

Solar flux is 73 and sunspot number 35. A=4 and K=2. 10m? No idea, but Es should be decent especially later.

21 Jun 2017

Pound against the Euro - NOT amateur radio

It is a year this week since the UK voted to leave the EU. I voted to remain.

It is my view that the Euro will lose value soon, probably this year. The UK was a major contributor to the EU finances and we will be missed. The Euro problems have not gone away, particularly Greece. Yes, the UK may be hurt in the short-term, but I cannot see this lasting.

Despite BREXIT, I am expecting the UK pound to gain value against the Euro, possibly as soon as this year. As I have said before, I could be completely wrong!

Storms?

For about a week now it has been very hot indeed for us. Today could be the hottest June day ever. Please someone tell the president of the USA. No, global warming is not a Chinese hoax. Just look at the real data.

Tomorrow, the weather could break with a return to more usual June weather here in the UK. With heavy thunder and lightning, maybe tomorrow will not be a good day to play radios? I shall be watching the maps.

See https://www.lightningmaps.org/?lang=en#y=52.9182;x=-3.2938;z=5;t=3;m=sat;r=0;s=0;o=0;b=0.00;n=0;d=2;dl=2;dc=0;

Market fruit and veg - NOT amateur radio

Bury St Edmunds, Suffolk. Market Day and lots of fresh fruit and veg on sale. Excellent. Bury is an "old fashioned" sort of place, but excellent for shopping. Great market still with some great bargains e.g. 3 magazines for £2.50 on one stall and they are only a few weeks old too.

Yesterday on 6m JT65

Yesterday was a good day on 6m JT65.

Stations were spotted in North America, South America and the Caribbean. I have dismissed the Indonesian spot as a pirate unless I am proved wrong.

At the moment, I am on 6m JT65 in beacon mode with 1W ERP. There is plentiful Es on 6m with spots (RX and TX) all across Europe.

UPDATE 1315z: Now RX only on 6m JT65.

UPDATE 1750z: Enabled 6m JT65 TX a few minutes ago.

Sunspots and 10m - Wednesday June 21st 2017

Solar flux is 73 today and the sunspot number 34. A=3 and K=1. Although there is 10m and 6m Es, it is some while since I noted 10m F2 here, although my 10m antenna is not great.

ICOM and Yaesu UK Prices

The IC7300 from ICOM retails at just under £1200 in the UK. The Yaesu FT891 retails for about half this at just under £600. OK, I know they are different radios, but both are 100W HF and 6m radios and the RX of the IC7300 has a much simpler SDR architecture.

Although I accept I may be wrong, these are my conclusions:
  • The IC7300 sells at a price people are prepared to pay and dealers are keeping the price as high they dare for as long as they can. It almost looks like the price is fixed between dealers. I am not saying it is, but it looks like this. Normally by now one has started to drop price, but this has not happened. The true price should be far less.
  • Yaesu sells the FT891 at just under £600 to tempt buyers. They may be trying to buy market share. I note a new model Yaesu 2m/70cm handi sells for £129.
Looking at this, I'd guess that ICOM will be around for a while. Yaesu may decide this is not a market to remain in for too much longer? As I said, I could be totally wrong. Personally I hope both stay in the amateur market for a long time.

20 Jun 2017

Sunspots and 10m - Tuesday June 20th 2017

Solar flux is 73 today. Sunspot number is 26. A=5 and K=1.

This year has flown by! It is hard to believe we are so close to the longest day and soon nights will start to lengthen.

Lots of Es about on 10m and 6m.

10m WSPR TX

As usual, I am active on 10m WSPR TX (500mW). Lots of Es spots. 30 unique spots in the last 12 hours.

6m JT65 real DX - real and fictional?

Just spotted K1TOL (5082km) in Maine, USA on 6m JT65.  I am sure this is true having worked this well equipped station some years ago on 6m CW.

Also, I spotted (supposedly) yet another Indonesian on 6m JT65. I have lost count of the number of Indonesians on 6m JT65. Unless proved otherwise, I think these are false decodes or pirates.

UPDATE 1600z: WP2B (6804km) in the US Virgin Islands in the Caribbean was spotted earlier. Judging by others who also spotted him, I think he is genuine.

UPDATE 2055z: PV8DX (7830km) in northern Brazil is the latest 6m JT65 DX earlier this evening.

19 Jun 2017

10m WSPR TX

As the 500mW 10m WSPR beacon was looking lonely, I decided to turn it on earlier this afternoon. So far, Es spots in northern Spain and Austria on 10m WSPR.

Another hot day ahead - NOT amateur radio

This is a surprise! For a second day in a row, we had breakfast in the garden. It is already hot. For us in the UK this is exceptional. Even in the shade it was warm even at 8.30am. My wife as just been for a walk and says it is very hot.

Just 6m JT65 today

At the moment, 10m WSPR is proving too easy! Most days, my 500mW is spotted across Europe, so today I am just on 6m JT65 transceive.

Sunspots and 10m - Monday June 19th 2017

Solar flux is 74 and sunspot number 27. A=10 and K=2. There is already Es about.

Geostationary amateur satellites

We are used to geostationary satellites which carry TV signals from a fixed point: aim the dish in the right place in the sky and that is it. By contrast, amateur satellites are in a low and moving orbit, so they only stay in range for a short time and they have to be tracked in the sky.

All this could change next year when 2 satellites (containing amateur radio transponders) are placed in geosynchronous orbits. Aim your antennas once and fix them in place. A lot can go wrong - date slippage, failure on launch, failure to reach the right place in space, equipment failure etc. If these all go to plan, amateur radio could be quite different in a few years' time.

As we are approaching a period of very poor HF conditions, these satellites could be a godsend. One is aimed to give good coverage over the Americas. The other covers Europe, Middle East and Africa mainly.

18 Jun 2017

Old FT817

Looking through some old photo albums, I spotted me with an FT817 in the garden dated 2001. This means I first bought the FT817 at least 16 years ago. I was probably working OX (Greenland) at the time, with 2.5W and a telescopic whip on SSB. It seems amazing that it has been around all that time with effectively no competition.

Another thing that struck me was how young and thin we looked back then!

10m WSPR

As usual, I am on 10m WSPR TX (500mW) with my WSPR beacon. Plenty of Es spots from across Europe today.

UPDATE 1314z: 20 unique spots of my 10m 500mW WSPR so far today.

UPDATE 1640z: 59 unique spots of my 10m 500mW WSPR in the last day (34 in last 12 hours).

UPDATE 2008z: 52 unique 10m WSPR spots of my 500mW beacon in last 12 hours - a good day. Going QRT shortly on 10m.

House martins (birds) - NOT amateur radio

A few days ago I saw my first house martins this year in the UK. This is much later than usual, so I wonder if numbers are down? These were in a nearby village. I've seen none in our village this year.

There seem to be plenty of swifts  - there were about 20 feeding overhead last evening - but house martins and swallows seem to be fewer this year. This may be a localised thing, but I notice numbers seem down.

Anyone know the facts?

Hot and sunny - NOT amateur radio

Something unusual has appeared in the UK skies. I think it is called "the sun". 😊

Actually it has been hot now for several days. Today we even had breakfast in the garden. For us in the UK this is a rare treat. Summer time, the temperature is often pleasantly warm at 18-22 deg C, but it has been HOT in recent days. Even sitting in the shade at breakfast felt warm and comfortable.

This robin (see photo) preferred the fat balls to the mealworms (eventually).

Sunspots and 10m - Sunday June 18th 2017

Solar flux is 74 today and the sunspot number 28. A=15 and K=2. There is Es about on both 10m and 6m, but I have see no evidence here of F layer propagation on 10m for several days.

6m JT65

My 1W ERP 6m JT65 has been widely spotted today throughout Europe. At the moment, I am RX only on 6m.  Some stations are working the Far East. I am unsure of the propagation, but this looks different from the breakfast paths to Japan.

UPDATE 1315z: Best DX today on 6mJT65 RX is VR2XMT (9537km) in Hong Kong. He is being widely spotted around the globe, so I think this is genuine.

UPDATE 2015z: Absolutely loads of 6m JT65 spots given and received today. Best DX on TX was Iceland and the Canaries. Think I'll stay on longer, hoping for some real DX reports!

17 Jun 2017

10m WSPR

Today 10m WSPR is nothing like yesterday. Although I have been spotted in Germany and by a local, 10m is nowhere near as good as Friday here. There is Es, but not like yesterday.

Another Indonesian on 6m JT65?

Today, out of the blue, I (supposedly) spotted 7A4TOI (13582km) in Indonesia at 1145z on 6m JT65. Although this could be genuine, I am pretty sure this station is a pirate somewhere in Europe. It would be great if this was a true 6m spot.

UPDATE 1933z: The Caribbean and South America now being spotted on 6m JT65. I think these are genuine!

Sunspots and 10m - Saturday June 17th 2017

Solar flux is 74 today and the sunspot number 28. A=24 and K=4. 10m? Maybe Es but F layer doubtful, especially with K=4.

UPDATE 0915z: No sign of Es on 10m or 6m here yet.

What a difference a day makes

Yesterday I had spotted lots of Japanese stations by now on 6m JT65. Today my only spots so far on 6m JT65 have been G stations. No Es yet on the band here.

UPDATE 1330z: Some Es now on 6m JT65.

16 Jun 2017

Long long 6m JT65 paths - what mode?

The very long paths on 6m JT65 are intriguing me. The common wisdom is these are "multi-hop sporadic E". Sorry, but I just don't believe it.

Some paths may be multi-hop Es sometimes (e.g. to Israel) but I think we are seeing some other sort of E layer propagation, maybe some sort of chordal hop? The Far East spots may be due to mesospheric cloud ionisation?

Some of the very long 6m paths may be pirates, but the Japanese spots are genuine and have occurred several times already in the last few weeks.

I am no propagation expert, but would love to hear from experts who might really know what is going on.

We are in 2017 and there are still unsolved mysteries.

What amazes me is there appears to be no-one trying to span Europe to Japan on higher VHF bands or even microwaves. This path opens every year at this time on 6m and should be possible at higher frequencies especially with big antennas and high power such as stations equipped for 23cm EME. Suitably equipped stations know where to beam, know when, know the best times. So? If you are suitably equipped set up some skeds!

10m WSPR

Yet again, I am on 10m WSPR TX (500mW) as well as 6m JT65 transceive (1W ERP).

Sunspots and 10m - Friday June 16th 2017

Solar flux is 77 today. Sunspot number is 28 today. A=4 and K=2. 10m? Well there is plenty of Es on 10m and 6m, but no F layer propagation noted here.

13 Japanese stations spotted today on 6m JT65

This is the best day so far this season on 6m JT65 with 13 (thirteen) different Japanese stations spotted around breakfast time today. Interesting that none at all was from Tokyo or its suburbs. Sadly, no spots of me from Japan.

I am amazed how easily I am spotting these with my poor setup here.

At the moment, I am still on 6m JT65 in beacon mode sending "B G3XBM JO02" near the top of the JT65 sub-section.

UPDATE 0932z: as well as all the Japanese spots on 6m JT65 I notice 7A7YYZ (13582km) was spotted early on 6m JT65. If genuine, this is long way on a VHF band. I have spotted different Indonesians several times, and find it hard to think they are all pirates. There were so many Japanese that I am sure Far East 6m propagation is genuine.

15 Jun 2017

Gilbert and Sullivan - NOT amateur radio

Every year, about this time, we attend a performance of Gilbert and Sullivan (Victorian comic opera) in a barn in a local village. This is an amateur cast but the performance is always first class. This year they did "Princess Ida", a work with which I was not familiar.

Sibling reunion - NOT amateur radio

For the last few days we have hosted our annual "sibling reunion" in which my wife's brothers and their wives join us. Each year, we take it in turns to act as hosts. The photo shows us in our garden earlier.

Top Band Loft Antenna

Some years ago, at the old QTH, I was looking for an easy 160m antenna, mainly for local use and WSPR. This antenna was the result. It exceeded all expectations.

See https://sites.google.com/site/g3xbmqrp3/antennas/160m_loft_ant

4el 70cm yagi

Some years ago I hastily made this small yagi to use portable on 70cms. The pole is just cheap PVC pipe and the yagi made from old coat hangers. It worked well and I still have it, although it has not been used for some time.yagi,70cm

10m WSPR TX and 6m JT65 transceive

As usual, I am on 10m WSPR TX only (500mW) and 6m JT65 (1W ERP) transceive. Already there is good European Es on both bands.

UPDATE 1305z: Yet again 4X1RF (3518km) has spotted me on 6m JT65. He has done so for many seasons now.

UPDATE 1518z: I spotted a station in Kuwait earlier on 6m JT65 - 9K2GS (4641km) and supposedly S65GBD (10734km) in Singapore. I have grave doubts about this last one.

UPDATE 1630z: First Caribbean station spotted on 6m JT65 this season. WP4JCF (6830km) in Puerto Rico copied.

Sunspots and 10m - Thursday June 15th 2017

Solar flux is 75 and the sunspot number 11. A=5 and K=1. 10m? Lots of Es around already.

14 Jun 2017

Greenland on 6m JT65

OX3LX (2570km) copied me on 6m JT65 earlier this evening. As far as I remember this is the first tine I have reached Greenland on 6m.

I remember working Greenland from the garden with 2.5W SSB and a whip antenna on 10m some years ago. I am pretty sure both these were Es.

UPDATE 0754 June 15th 2017: He spotted me again late yesterday.

Sunspots and 10m - Wednesday June 14th 2017

Solar flux is 73 and the sunspot number 11. A=8 and K=1.

70cm UKAC missed

This RSGB 70cm activity contest was last night, but I had to give it a miss as we had visitors. Usually my far from ideal antenna and 5W SSB reaches the Midlands (over 100km). I use a 2m halo fed with lossy coax on 70cm. I am amazed how well this works on 70cm. Match is good, but I have no idea of the radiation pattern.

6m JT65 super DX?

Once again, I spotted a station in Indonesia on 6m JT65. 7A5FHZ (11934km) was spotted very early. I am suspicious as this is a very long way on 6m and the signal was very strong. There were quite a few Es spots around Europe.

UPDATE 1700z: The same Indonesian station was spotted at lunchtime - suspicious? I am highly doubtful.

Old charabang - NOT amateur radio

We had some visitors who arrived at our local museum in this old coach. This is it parked outside the windmill.

The word charabanc is from French 'char-bancs', meaning a carriage with benches, so I read.

Our home is on the left in the picture.

Sunset - NOT amateur radio

In the UK we are blessed with seasons. In mid-winter it is dark at 4pm, but in mid-summer it is light until 10pm. Every season has something good about it. This shot was taken from our garden at 12 minutes to 10pm on Sunday, June 11th, 2017.

Sunspots and 10m - Tuesday June 13th 2017

Solar flux is 75 today and the sunspot number remains zero. A=8 and K=2. There is Es on 10m, but no F2 propagation seen here.

Back on 6m JT65 transceive and 10m WSPR TX

Since breakfast, I have been active as usual on 10n WSPR TX (500mW) and 6m JT65 transceive (1W ERP). On 6m G spots only so far but some early Es on 10m WSPR.

UPDATE 0934z: Now some Es on 6m JT65. EA5/G3XGS (1581km) has spotted me. Most 10m WSPR spots have been from Northern Europe so far.

UPDATE 1334z: although I am being widely spotted across Europe on 6m JT65, my own spots of others are not appearing on PSK Reporter Maps. Maybe it has forgotten the tick box for some reason or my internet upload is not working?

12 Jun 2017

QRT

As the DX appears to have stopped, I am about to go QRT and turn off the PC.

Bird table visitor - NOT amateur radio

Every day we get jackdaws on our bird table. They are quite big birds, but quite fun. This one is busy tucking in to kitchen scraps. We now get quite a variety of birds. I think they know there is free food on offer! The starlings love the fat balls. A refill on Saturday was totally empty on Sunday.

Wireless charging from roads - NOT amateur radio

To me, this has to be the answer to a carbonless future with regard to road vehicles. Southgate News reports on trials in France and Israel where the road has embedded wireless charging for road vehicles. This means smaller, lighter, batteries in the vehicles, a longer battery life, and greater range.

See http://southgatearc.org/news/2017/june/roads-with-built-in-wireless-charging.htm#.WT5ai7pFzmQ

Sunspots and 10m - Monday June 12th 2017

Solar flux is 75 today and the sunspot number remains zero. A=17 and K=2. There is Es on 10m and 6m.

10m WSPR (TX) and 6m JT65 (RX)

At the moment I am on the above modes and bands. If WSJT-X V1.7 and PSK Reporter Maps support JT9E, I may give this mode a try on 6m later on 50.290MHz.

UPDATE 1028z: Best DX on 6m JT65 RX is S65KXA (10734km) in Singapore. No Far East  (Japan, Korea etc.) spotted today.

UPDATE 1145z: 12 unique 10m WSPR spots of my 500mW 10m WSPR beacon today so far.

UPDATE 1720z: After a brief period on JT9E on 6m (nothing) I have returned to 6m JT65 transceive where I have been received across Europe by Es.

11 Jun 2017

Same old stations on 10m WSPR

Unlike 6m JT65 where I frequently spot new stations and get spotted by new stations, in general my 10m 500mW TX beacon signal is received by the same European stations. The level of WSPR activity on 10m is definitely lower than 6m JT65. I only use 10m WSPR TX as this uses a different rig and antenna.

Out of choice, if I had to make one, I'd choose 6m JT65 in the Es season.

Hedge cutting - NOT amateur radio

Our laurel hedge in our front garden needs cutting several times a year to keep it in check. It makes a nice barrier, but we don't want it too high.

I swept up several wheel barrows of clippings. The photos shows me flicking the cuttings from the top of the hedge onto the grass.

As you can see, that 200 year old windmill really is "next door".

Poor Mrs May - NOT amateur radio

For a start, I was one of the many millions in the UK who did not vote for Mrs May (UK Prime minister) and the Conservatives. It looks like the rich are richer and the poor poorer under her party. This is wrong. If we are to have austerity let us all share the pain. As for a working alliance with the Democratic Unionists (DUP) in Northern Ireland, I am sure this will go down in history as a mistake.

To be fair, many expected a landslide with the Conservatives winning a big, clear, majority.  Instead, we ended up with a hung parliament and Mrs May hanging on by a whisker.  Most people rejected her autocratic style.

In some way I feel sorry for her. A week ago she could do no wrong, whereas now she is vilified.

Who knows what the future holds? It will be several years before the dust settles,  but beware any party that ignores the people it serves.

Oh, we still await a true charismatic leader in any UK party.

New near real time propagation tools

My thanks to Southgate News for bringing this to my attention.

Jim Bacon, G3YLA has a new propagation tool, which is worth linking. Jim does the TV weather in East Anglia, and is a well regarded Es expert.

See http://www.convectiveweather.co.uk/ionosphere/index.php

That letter Y - NOT amateur radio

Many many years ago I attended Salcombe Boy's Club. This was back in the 1950s when I was still very young. We played indoor sports followed by a brief religious service taken by 2 very kind men.

It is funny how some things stick even 60 years later. One of these was Mr Putt telling us how life was like the letter Y. The Y has two ends at the top, like life: you frequently have to choose a direction to go in. Often there is an easier path and a more difficult one. Often I reflect and wonder what would have happened had I followed a different path in life. This is a theme I have mentioned before.

What if I had gone to a different university or no university at all? What if I had got poor grades at A level? What if I had changed jobs and moved? What if I did that PhD that I turned down? I guess we can never know. Life is filled with such Y moments, but we do not realise it at the time. Perhaps in a multiverse we do take every path, but are only aware of one?

10m and 6m

As usual, I am on 6m JT65 and 10m WSPR TX. There is Es on both bands.

UPDATE 1700z:  A45XR (5796km) in Oman is the best DX on 6m JT65 RX today so far. I am convinced there are far more people now using this mode on 6m. Conditions for Es may be better this year, but I am sure the (great) levels of JT65 6m activity are helping.

UPDATE 2105z: 10m WSPR TX now QRT and RX only on 6m JT65.

Sunspots and 10m - Sunday June 11th 2017

Solar flux is 74 today. Sunspot number is zero again. A=4 and K=2. There is Es on 10m and 6m, but no signs of F2 propagation DX.

10 Jun 2017

10m WSPR TX

As on previous mornings, I am on 10m WSPR TX (500mW) with my stand-alone WSPR beacon. Plenty of EU spots, but no spots from further afield.

Es better this year?

The impression I am getting is that this Es season is better than the last one. Certainly, I seem to be copying more on 6m JT65 than last year.

What do you think?

Yet more stroke artefacts - NOT amateur radio

Yet another after-effect of my 2013 stroke is that I am less able to see spelling errors. In the past I'd just look at a word and know the spelling was wrong. These days I find it much harder to see these. It is as if my brain is functioning differently.

Also, I drive slower than in the past and worry more in general. Stroke (?), although I am getting older anyway.

Inference is different too, often seeing potential dangers that others miss. What is hard to tell is, "is this real?".

Even nearly 4 years after the stroke, I still have effects - I still feel giddy on my feet, thin liquids are a problem and my voice is poor. I get tired easily too.

Sunspots and 10m - Saturday June 10th 2017

Solar flux is 73 today and the sunspot number zero. A=5 and K=1. There is widespread 10m and 6m Es, but no signs here of F2 DX on 10m.

6m JT65

This morning, I am again on 6m JT65 receive after a very brief transceive period (1W ERP). Best DX so far are Israel, Jordan JY9FC (3650km) and Bahrain A92GE (5068km).

UPDATE 1022z: Although I see some EU stations are working JAs on 6m this morning, I spotted none today. I guess they have better gear or the propagation was right for them.

Amateur radio prices

Just now, I received an email from MLS giving details of their "something for the weekend" special offers. Now I appreciate that dealers have to make a profit - after all, this is their business - but I remain amazed by some of the prices. All dealers are similar, so I am not singling out MLS.

For example, one HF antenna sells for £409 when the manufacturing cost is unlikely to be more than £10, especially if made in China. Someone is making a huge profit. Of course, dealers sell for the prices we are prepared to pay. Reasonable is fine, but rip-offs are not. More fool us for playing the game.

In 20 years many dealers will be gone. Those that remain should be those that provide a good service, make reasonable profits and do not rip off their customers. Any dealer that rips off customers deserves to fail.

Low cost amateur radio

As many of you know I am a miser who does not like spending money on amateur radio. My ethos has always been to get the most for the least money. If I do spend real money, it is an investment that has to last years. My FT817 is almost 17 years old!

Perhaps this is one reason why I have always liked QRP: gear is low cost to make and every contact gives you a sense of pride, especially if home made. I hope you can take some inspiration from the various projects on my main website.

See http://www.g3xbm.co.uk . Drill down on each page to find all the various projects.

ARRL book about JT65 and JT9

There is an ARRL book on the digital modes JT65 and JT9. These are among my favourite modes and ideally suited to QRP. I have used JT9 on bands up to 10m. I have used JT65 on bands up to 6m.

See http://www.arrl.org/shop/Work-the-World-with-JT65-and-JT9/ .

At the moment there is a special ARRL deal so you get this book free when you buy a new ARRL Handbook.

9 Jun 2017

6m to the USA (again)

JT65 is proving useful for finding brief Es openings on 6m. In the last hour WN5LUF (6886km) in Missouri just appeared and disappeared. Maybe others will appear and maybe not. Earlier in the day a station in New England just came and went on 6m JT65.

Although you might expect 10m WSPR to be better, I seem to get better results on 6m JT65. This could be down to antennas, although there seems to be more activity on 6m JT65 than 10m WSPR.

New 6m yagi

Hype! 

Although I have copied JA for 3 days on the trot on 6m JT65 I see InnoVAntennas want you to part with lots of money. Here I just have a triband omni vertical fed with lossy CB coax and an FT817.

Don't believe hype. You can enjoy the hobby spending very little.

OK, I agree that a big yagi may help, but I seem to do fine with a very modest station.

See http://www.innovantennas.com/antennas-a-accesories/on-line-shop/view/productdetails/virtuemart_product_id/507/virtuemart_category_id/3.html

If I erected the MONSTER shown on the Southgate News page my neighbours would have a fit! No, you can enjoy the hobby much more modestly. Each to their own, but to me this is not amateur radio.

See http://southgatearc.org/news/2017/june/lfa-3-third-generation-lfa-yagi-make-ja-possible-on-6m.htm#.WTp

If I wanted to talk to the USA and Japan why not use Skype?

Sunspots and 10m - Friday June 9th 2017

Solar flux is 72 today and the sunspot number 12. A=4 and K=1.

Plenty of 10m Es about, although I have not received any F layer reports of my 500mW 10m WSPR.

Back on 6m JT65 (but higher up the segment)

Earlier this morning, I returned to 6m JT65 (transceive - 1W ERP) but I have moved slightly higher to avoid causing local issues. There is a lot of Es and my signal has been widely copied in Europe. Last night Canada was copied on 6m JT65 in the form of VE3DS (5711km). As yet, no Far East stations received on 6m JT65: yesterday it was a bit later that they came through.

UPDATE 1052z: Both Israel and Bahrain spotted on 6m JT65 RX, but nothing from the Far East today. A92GE (5068km) is currently to best RX DX on 6m this morning.

6m JT65 QSY

Some locals have complained that my beacon mode "B G3XBM JO02" transmissions are causing some local issues, so I have QSYed a little further up the band when not looking for 2-way contacts.

I use beacon mode so that I can look on PSK reporter maps to see where I am reaching. I do not use this beacon unattended. At the same time, I do not want to cause anyone problems. At the moment, I am RX only on 6m JT65.

Japan (again) and South Korea on 6m JT65 this morning

For the third morning in a row Japan was again coming in on 6m JT65. Today there were 10 Japanese stations copied! Also a couple of South Koreans. Amazing conditions for a VHF band! All this was around 0830-1000z.

There was also a spot of C3NY/UM0NGN, but I was not sure if this was Andorra or Turkmenistan!

The best DX on 6m JT65 RX was 9495km - quite an incredible distance for a VHF band.

Broadband interference?

If you were thinking of complaining to OFCOM about broadband noise you may want to think again.

See http://www.ispreview.co.uk/index.php/2017/06/ofcom-finds-no-evidence-claims-interference-vdsl-broadband.html

The fact that our HF noise floor is gradually getting worse is of little concern to OFCOM. Only money matters sadly. In the UK the amateur radio service is unimportant.

6m JT65

This morning I am again on 6m JT65 transceive (currently in beacon mode) running 1W ERP. There is already Es on the band, with spots on RX and TX from all over Europe.

No Japanese stations copied here on 6m JT65 today. Last night, 6m opened to the USA with 8 unique USA stations spotted on 6m JT65. Japanese stations were spotted on 6m JT65 both yesterday and the day before.

10m WSPR

As usual, I am on 10m WSPR TX with my 500mW WSPR beacon.

Yesterday was quite productive on 10m WSPR TX  with 42 unique spots in the last day (see photo).

Sunspots and 10m - Thursday June 8th 2017

Already there is Es on 10m and 6m. No 10m F2 seen here on 10m yesterday.

Today, the solar flux is 74 and the sunspot number 13. A=4 and K=0.

UK General Election today: VOTE - NOT amateur radio

This is your chance to back the candidate of your choice. Whatever your political persuasion, I urge you to use your vote. Voting is private, so only you know the person for whom you voted.

7 Jun 2017

General Election in the UK tomorrow - NOT amateur radio

Whatever your political views you have a democratic right to vote for the candidate of your choice. A vote not used is just wasted. Use it, please.

Even if your choice does not get elected, it tells the others of your support.

10m WSPR

My 500mW 10m WSPR beacon is on TX again. So far just one spot received from IU1DZZ (973km).

UPDATE 1424z: Although there is Es right across Europe, I get the feeling there is less than yesterday? 13 unique spots of my 500mW so far. All Europeans.

UPDATE 1644z: 23 unique spots so far with best DX SQ2DMX (1268km).

Japan again copied on 6m JT65

Although not reported to PSK reporter maps I again spotted Japan on 6m JT65 this morning when JH6VXP (-23dB S/N) was copied calling a European at 0749z. There is plenty of European Es on 6m this morning as well as 4X4.

UPDATE 1420z:  Although there is reasonable amount of Es on 6m JT65, I think there is a bit less than yesterday.

UPDATE 2126z: 6m JT65 has opened to the USA this evening after an excellent Es day. My 1W ERP JT65 was widely copied across Europe.

Sunspots and 10m - Wednesday June 7th 2017

Solar flux is 76 today and the sunspot number 18. A=5 and K=2.

UPDATE 2000z: 5 QSOs before I had to go QRT because of my poor voice.

Amateur satellites

I'm all my time, I have only ever had one QSO via an amateur satellite. Back in the 1970s I recall the thrill of hearing SSB from the USA on 2m via Oscar 6 and 7, fleetingly.  Some people love working stations through satellite transponders. I see from Southgate News that one station is close to DXCC via satellites.

See http://southgatearc.org/news/2017/june/dxcc-needs-on-the-birds.htm#.WTaS97pFzIU .

Sunspots and 10m - Tuesday June 6th 2017

Solar flux is 78 today and the sunspot number 22. A=5 and K=1. There has been good Es propagation on 10m and 6m today. As for F2 over the equator, we'll see later.

Another pirate on 6m JT65?

A station in Georgia (nr Russia) was recently spotted on 6m JT65. This had a very odd call, so this was, I think, either a false decode or a pirate.

10m WSPR TX

13 unique WSPR spots of my 500mW beacon on 10m so far, all European and presumably Es.

UPDATE 1838z: Best DX report today on 10m WSPR TX (500mW) is by FY5KE (7110km) in French Guiana, South America. Es?

First JAs this season on 6m JT65

Copied a couple of Japanese stations early this morning on 6m JT65, first this season - JA5FFJ (9453km) and JG3QZN (9388km). Openings on 6m to Japan from Europe happen at this time of year. One possibility is E layer ionisation by mesospheric clouds which form high up at this time of year in the north. See my web page on this at https://sites.google.com/site/g3xbmqrp3/vuhf/noctilucent .  W was widely spotted throughout Europe by Es on 6m JT65 this morning (1W ERP).

I am sure there is more JT65 activity these days. It is better than CW. With PSK reporter maps (you need to check you WSJT-X v1.7 settings) you can see where you are reaching and the stations you are receiving.

A spot of a South American earlier on 6m JT65 was probably a pirate (unusual time), although it is just possible by Es.

5 Jun 2017

IC7300 and a slow death?

Recently, Rob Sherwood gave an interesting video presentation on disruptive technology in our hobby. In it he quoted the number of ICOM IC7300 transceivers sold in the first year. If I recall correctly, 11000 (ish) were sold in year one. Apparently, this is good. If the IC7300 SDR based radio sold this number, I'd guess Yaesu and Kenwood sold far fewer of their units.

Incidentally, when I was involved in radio pager design in the late 1990s, we made this number in one day!

As we get older, we can expect the numbers to fall away. People die and fewer new rigs get sold. In the end the Japanese manufacturers will decide it is just not worth their while as the profit margins are too small. Expect progressively fewer new models as the years go forward.

OK, in some countries there are younger people entering the hobby, but certainly here in the UK amateur radio is an old mans hobby and in 20-30 years we'll be gone.

One thing we'll see is cost cutting. There will be a move to SDR technology, as this will allow good performance for less money.

Expect dealers to dwindle and there to be fewer radio magazines. The hobby will be quite different in 2040.

Once again, I am grateful to Southgate News for this link.

New microwave records

Southgate News reports on new microwave distance records in the UK on high microwave bands.

Sunspots and 10m - Monday June 5th 2017

Solar flux is 77 today and the sunspot number 23. A=3 and K=2. Plenty of Es about on 10m and 6m.

10m WSPR TX and 6m JT65 transceive

As usual, I am on 10m WSPR TX (500mW, 100%) and 6m JT65 transceiver (1W ERP). There is Es on both bands.

UPDATE 1015z:  Best DX so far on 6m JT65 RX is EA8DBM (3015km).

UPDATE 1625z: Best DX on 10m WSPR TX is SM2BYC (2015km). On 6m JT65 I have supposedly received my 3rd Indonesian, 7A7YYZ (13582km), although I am a bit suspicious of these spots. They seem a very long way.

UPDATE 1956z: Although not showing up on my PSK reporter map, maybe I lost internet connectivity (?) but WP2B was copied around 30 minutes ago. I think this is the Virgin Is in the Caribbean.

CQ Japan on 6m JT65

It is that time of year when 6m opens from Europe to Japan on 6m. This morning I see that Spanish stations are calling JA on 6m JT65. This path opens every year on 6m around this time. The conventional view is this is multi-hop Es. Sorry, but I don't go for this. It may have something to do with E layer ionisation as a result of noctilucent clouds?

See https://sites.google.com/site/g3xbmqrp3/vuhf/noctilucent .

4 Jun 2017

20m? No, 6m!!

The photo shows the results so far on 6m JT65. It looks more like 20m, but this was 6m VHF today. Quite amazing conditions. And my antenna is a humble V2000 omni vertical fed with lossy CB coax.
UPDATE 2018z: WA1EAZ (5274km) in the USA was the first USA station spotted on the band here this year.

10m WSPR TX

The 500mW WSPR beacon has been running all day. Lots of European Es spots (see photo of the unique stations so far), although no reports from further afield.
UPDATE 1702z:  So far, 20 unique stations spotting me on 10m WSPR with best DX 1734km

QRP and QRP Club

Oleg's usual update:

Sunspots and 10m - Sunday 4th June 2017

Solar flux is 77 today and the sunspot number is 22. A=9 and K=1. Both 10m and 6m are alive with Es.

Re-installed WSJT-X V1.7

My version of this program started to do odd things, so I deleted it and re-installed it.

Currently I am on 6m JT65 (beacon mode transceiver, 1W ERP) and 10m WSPR (500mW, 100% TX using the stand-alone beacon).

UPDATE 1522z: Best DX on 6m JT65 RX is TY2AC (5109km) in Benin, W.Africa and 3J3AGK (7646km) in China.

3 Jun 2017

No storm risk

As the nearest storms are a long way away, I think I'll leave my 10m WSPR TX and 6m JT65 transceive running overnight.

See https://www.lightningmaps.org/?lang=en#y=52.2238;x=-4.5678;z=5;t=3;m=sat;r=0;s=0;o=0;b=0.00;n=0;d=2;dl=2;dc=0;

UPDATE 2135z:  With nothing great happening I have decided to turn things off and save the electricity.  I know, in the morning someone will tell me I missed the best transatlantic 6m conditions in years!

WSPR versus JT65

For the last couple of years I have been comparing WSPR versus JT65 on 10m and 6m. Theoretically, WSPR is a little better, but I seem to get much better results with JT65. Maybe it is because the TX period on JT65 is shorter, so transient openings are seen? Maybe there is more JT65 activity?

With my little 500mW 10m W5OLF WSPR beacon, I can be on 10m WSPR TX whilst using the shack PC and FT817 for 6m JT65. These use different antennas.

I really ought to try PSK31 too. Later!

UPDATE 1758z:  Today on 10m WSPR no spots at all. On 6m JT65 plenty of Es spots given and received. Best DX on 6m JT65 RX was 4X4DK (3582km).

Manchester Terror Attack - NOT amateur radio

Sadly Manchester was the centre of a terrorist attack which killed 22 and injured many more, mainly children and young girls. It was a pointless, evil act, carried out by someone who could not care less about those he injured or killed. My wife's nephew knew one of the victims, so the pointlessness of this evil act hit us on a personal level. Look, evil in the form of terrorism will never, ever win. As for vestal virgins awaiting the perpetrators in Heaven, I think the very opposite awaits!

See http://www.bbc.co.uk/news/uk-england-manchester-40141450 .

"Real" DX on 6m

At the moment, F2 worldwide 6m DX is rare and we rely on Es to get decent ranges. Es tends to peak in the late spring and summer. "Real" DX, by which I mean ranges well in excess of normal Es ranges, seems to occur when Es is good, although I am not a great believer these are due to multi-hop Es. OK, some might be, but I think some of the distances suggest some kind of chordal hop Es. I am frequently wrong!

UK to Israel even with my poor antenna and lossy coax and QRP every summer for several years? Also, occasional reception at much greater ranges on 6m?

I'd be interested to hear your views, especially from real experts with far more knowledge than I'll ever have. These long distance Es paths have puzzled me for years. They do happen most seasons, if not all Es seasons.

Sunspots and 10m - Saturday June 3rd 2017

Solar flux is 77 today and the sunspot number 19. A=5 and K=1.

6m JT65

One correspondent tells me 6m JT65 stations on the west coast of the USA were able to work Europeans on 6m yesterday. Although there is some Es around today, conditions here are nothing like they were yesterday. I am active on 6m JT65, but so far most spots are Gs with a few EU stations.

UPDATE 1128z: Best DX spot today on 6m JT65 TX, so far, is LA1BFA (1331km).

10m WSPR TX

Once again I have my 500mW WSPR beacon TXing on 10m. As yet, no spots. Yesterday by this time I had been copied all over Europe by Es.

Storms and 6m

Today has been the best day this Es season here on 6m, so I am keen to stay on this evening. Storms are currently to the east, so I'll remain on until bedtime, but ready to disconnect plugs at any time.

See https://www.lightningmaps.org/?lang=en#y=52.2238;x=-3.0297;z=6;t=3;m=sat;r=0;s=0;o=0;b=0.00;n=0;d=2;dl=2;dc=0;

UPDATE 2100z: Still active on 10m WSPR TX and 6m JT65 transceive, but no transatlantic spots.

Close run? - NOT amateur radio

The UK General Election could be much closer than was expected. Of course, pollsters may be very wrong, but Labour seem to be doing much better than was expected. On the day what matters is who decides to vote.

See http://www.bbc.co.uk/news/election-2017-39856354 .

Sunspots and 10m - Friday June 2nd 2017

Solar flux is 81 today and the sunspot number 18. A=7 and K=1.

Conditions on 10m are good by Es and 6m conditions (Es?) seem exceptional (see earlier post).

10m WSPR TX

All morning, I have been on 10m WSPR TX (500mW, 100%). My signal is being widely received across Europe.

UPDATE 1455z: 34 unique spots of my 10m WSPR. All were in Europe.

6m JT65 - amazing conditions

Just spotted 7A4TOI (13582km) in Indonesia on 6m VHF!! This is the greatest distance I have ever received on a VHF band. Extraordinary long path - Es?  My own 1W ERP 6m JT65 signal was copied in Israel earlier by 4Z5ML (3571km).  Conditions on 6m seem extraordinary today.
UPDATE 1100z: At one time receiving Qatar and Asiatic Russia (5210km) would have seemed exceptional on 6m - both copied this morning on my poor antenna. Now I expect anything!

UPDATE 1600z: Today, 6m JT65 has been more like 20m with lots and lots of spots of my 1W ERP signal. I hope we see transatlantic DX this evening. It may not happen, but after today it is anyone's guess.

General Election in the UK - NOT amateur radio

We have a General Election in the UK next week. At the beginning of the campaign, the pundits were talking of a landslide victory for the ruling Conservative Party. Now, in the last week, things are much closer. Last time the experts were wrong. It will be interesting to see who is right.

Personally, I think we have a real lack of good leaders in all main parties. What we need is a "centre ground" party with strong, charismatic leadership. There is little to chose between the three main parties: the right of the Labour Party is very similar to the left of the Conservatives and the Liberal Democrats are somewhere there too. Not one of these parties has what I'd call a good leader.

Home quiet - NOT amateur radio

We have had all our 4 grandchildren and parents here over the last week. These days I find them very tiring. It is great having them and it is "clean mess". Once they have all gone, the house does seem empty, but tidy!

CQ-DATV

TV is one part of our hobby I have never tried. After all, it is hard to do everything! If you are interested in DATV, issues of CQ-DATV may be downloaded freely.

See http://cq-datv.mobi/48.php  for the latest issue.

10m JT65 again

Once again, I am on 10m JT65. So far, just Europeans by Es. Yesterday was a good day with plenty of South Americans coming through on 10m JT65 in the late afternoon and evening.

UPDATE 2028z: After another good 10m JT65 Es day, it is time to go QRT. Tomorrow I may try 10m WSPR TX and 6m JT65 transceive.

OFCOM and mobile phones on ships - NOT amateur radio

See http://ofcom.createsend1.com/t/ViewEmail/i/742AAB4E823BB885/59D1BD3EA2F08127C67FD2F38AC4859C

OFCOM is consulting on the use of mobile phones on ships.

Sunspots and 10m - June 1st 2017

Solar flux today is 75 . Sunspot number is 11. A=4 and K=1. Widespread 10m Es.

31 May 2017

10m JT65

Conditions seem quite good this morning. On 10m JT65 RX my best DX is UN7DA (5276km). My own signal is being widely copied in Europe by Es. Other notable RX spots include YI3WHR (4186km) in Iraq late last night. I find it hard to believe this is Es. F2 is possible although the time is wrong for F2.

Are these long paths Es with some sort of chordal hop? I have long suspected this sort of mode. I am not a great believer of these being multi-hop Es. It would be interesting to hear what experts have to say.

Sunspots and 10m - Wednesday May 31st 2017

Solar flux is 73 today. Sunspot number is zero. A=7 and K=2. 10m is likely to be livened up by Es in the northern hemisphere.

30 May 2017

TEP and 10m (and 6m)

Newcomers may not be aware that trans-equatorial (TEP) propagation can extend to quite high frequencies. If memory serves me right, the signals cross the magnetic equator by spread-F, a sort of chordal hop. I think 2m has been used to work from Southern Africa to the Med. Today, a number of South Americans have been copied in the UK on 10m JT65.  I suspect this is TEP being extended to the UK by Es. TEP does not usually extend this far north.

Baking - NOT amateur radio

Today, we had all 4 grandchildren (all 9 and under) here for lunch. Here is our elder granddaughter busy baking in the kitchen.

SAQ transmission cancelled

Southgate News reports that the upcoming SAQ CW transmission on 17.2kHz VLF CW has been cancelled due to ongoing maintenance work.  This signal is often a good one to try if testing your VLF system. It is much harder receiving amateur VLF signals.

Often these transmissions result in a QSL card for reports. I have one from years ago.


See http://southgatearc.org/news/2017/may/saq-transmission-cancelled.htm#.WS2KmrpFzIU

Sunspots and 10m - Tuesday May 30th 2017

Solar flux is 74 today and the sunspot number 16. A=10 and K=4.

10m JT65

This morning, I am on 10m JT65. As yet, no spots.

UPDATE 0848z: My 10m JT65 is being spotted in Switzerland and Austria  (Es) and the best DX on RX is the Canary Is.

UPDATE 1000z: Spots so far this morning on 10m JT65.
UPDATE 1614z: Best DX on RX was RA9N (4608km) in Omsk, Asiatic Russia. This is a long way for Es, if indeed this is the mode.

UPDATE 1715z: PY2FA (9580km) and another 3 Brazilians are now being spotted. Could be Es linking with TEP?

UPDATE 1957z: Now 8 South Americans spotted on 10m JT65 plus a couple of stations in the UAE at the far end of the Gulf. Still no spots of my own QRP 10m JT65 outside of Europe. Definitely a good Es day on 10m.

UPDATE 1725z: So far, 5 different Brazilians spotted on 10m JT65 today.

29 May 2017

G7 meeting - NOT amateur radio

This photo was widely shared on Facebook. I have no idea where it was first made. Sadly, this is how much of the world sees the president of the USA. He needs not to be a joke.

6m JT65

Last night, as a precaution, I went QRT and disconnected plugs and antennas. We had thunder and lightning overnight (I'm told) but I slept through it!

At the moment I am on 6m JT65 (1W ERP). Best DX on TX is 9A2DI (1532km). There have been G spots, ON (tropo or aircraft?) and Es on 6m. On 6m JT65 RX the best DX is EA8JK (3021km).

UPDATE 1112z:  As well as the Es, I have been spotted in Cornwall by G8BCG (372km) in IO70 square. If this was tropo, it was a long way.

UPDATE 1604z: Plenty of Es from/to Europe on 6m JT65 today. What would be really good would be if we got Es to the Caribbean or South America on 6m JT65. Although it feels quite humid here, there are no thunderstorms shown in the UK. Unless thing change I intend to stay on 6m JT65 until late this evening.

UPDATE 2040z: Although the Es spots seem to have stopped, there are still plenty of G spots. As the thunderstorms seem to be mainly in Belgium and Germany I am remaining on the air.

UPDATE 2140: Today, my QRP 1W ERP 6m JT65 was spotted by 9 UK stations and I spotted 23 stations in the UK.

Sunspots and 10m - Monday May 29th 2017

Solar flux is 77 today and the sunspot number is 20. A=51 and K=1.

28 May 2017

10m JT65

At the moment the sun is shining at there is no risk of storms until much later. I am on 10m JT65 and am likely to be using this band/mode most of the day. I am not expecting "real" DX, but there could be some Es around Europe. No spots so far today.

UPDATE 1115z: So far today just spots from G6SSN (75km) on 10m JT65. No Es. There are storms over the English Channel, moving our way. I need to keep an eye on these. but it is likely to be OK for several hours yet.

UPDATE 2112z: Widespread 10m Es with lots of spots of my 10m JT65. About to go QRT. Es still great!

Sunspots and 10m - Sunday May 28th 2017

Solar flux is 79 today and the sunspot number 21. A=14 and K=7. With disturbed conditions I am not expecting great things of 10m today, although Es may well help.

27 May 2017

Storm risk has passed - now on 10m JT65

As the storm risk has passed I have turned on my FT817 and PC on to 10m JT65. No JT65 spots as yet.

UPDATE 1945z: ZP5PIA (10275km) in Paraguay was the first station spotted n 10m JT65 at 1926z.

UPDATE 2045z: The station in Paraguay looks like the only station spotted on 10m JT65 since late this afternoon when I first switched on.

Enforced QRT - storms

There is thunder and lightning about so I decided not to go on the air today. You can track the storms at https://www.lightningmaps.org/?lang=en#y=52.2238;x=0.0464;z=6;t=3;m=sat;r=0;s=0;o=0;b=0.00;n=0;d=2;dl=2;dc=0;

Sunspots and 10m - Saturday May 27th 2017

Are ICOM and Yaesu struggling?

I am beginning to wonder if some of the large Japanese companies are getting tired of amateur radio.

When ICOM introduced the IC7300, Yaesu looked like they reacted and quickly brought out the FT991A. Yaesu seems to have "gone off the boil" in recent years. System Fusion is being pushed, but years after DSTAR. Most of us remember Betamax, VHS and Video 8. The last thing we want is a standards war.

There were no new products launched at Dayton, at least nothing was reported. I am beginning to think the Japanese have decided to introduce fewer amateur radio products. Perhaps they see a dwindling market with less profits in the coming years?

As for an FT817 successor - I think this is never happening.

Dayton Hamvention 2017

This was last weekend. It is possible I missed announcements, but nothing new appears to have been announced by the big manufacturers.

I have never been, nor am I likely to, but this is the big one. It moved venues this year. Looking at the photos, most attendees look old.

See http://hamvention.org/ .

Trident and terrorism - NOT amateur radio

Some estimates put the bill to replace our "independent" nuclear submarine fleet at more than £100 billion. Most countries don't have nuclear weapons, let alone an "independent" nuclear deterrent.  Even the Labour party supports Trident's replacement. This is at a time when we complain there are not enough police or people able to analyse people who may be a terrorist threat to the UK.

Why not scrap Trident and spend some of the money on police and anti-terrorism?

No-one in their right mind would press the nuclear button. It would lead to widespread death and destruction. We need things to counter the threats of today

As for nuclear deterrence, how do most countries manage without such weapons perfectly well? Just a small fraction of the Trident replacement costs would go a very long way.

Mobile phones on aircraft - NOT amateur radio

So, OFCOM has changed the rules to allow mobile phones on aircraft. I objected. In my view this is stupid idea. Imagine phones ringing all the time on a long flight. People managed in the past.

See http://ofcom.cmail20.com/t/ViewEmail/i/B17ECEB3D452F524/59D1BD3EA2F08127C67FD2F38AC4859C

Sunspots and 10m - Friday May 26th 2017

Solar flux is 77 today and the sunspot number 19. A=4 and K=1. I expect 10m will be good for South America later from the UK. We can also expect 10m and 6m Es.

6m JT65 today

Having had success for the last few days on 10m JT65, today I have switched to 6m JT65. So far, just spots from 3 G stations with the best DX being G8TTI (185km). This is either tropo or aircraft reflection. As usual, 1W ERP in use here from my V2000 omni vertical.

UPDATE 1056z: LX1JX (469km) is the best distance spotted so far today on 6m JT65. Probably too near for Es?

UPDATE 1230z: Still no sign of Es on 6m JT65 here.

UPDATE 1648z: Ten G station spots of my QRP 6m JT65 today, but no Es spots.

UPDATE 2002z: Eleven G spots of my QRP 6m JT65 today, but still no Es. Tomorrow may be a QRT day because of the storm risk.

UPDATE 2142z: Some very late Es spots of my 6m QRP JT65 from Portugal just before going QRT and disconnecting antennas, PC and plugs.

SW interval signals from the past

Many of us started in the hobby by building simple shortwave receivers and listening to the many broadcasters on shortwaves long ago. Did any of the communist stations really expect us to listen intently to their propaganda? I certainly did not! Mind you, I got some nice goodies from some. These days there are fewer and fewer BC stations on the air on shortwave, and very few in English.

If you want a dose of nostalgia try https://sites.google.com/site/g3xbmqrp3/hf/interval . A Google search will find others.

I miss these and I am sure I'm not alone. They speak of an age long past. Certainly we were no safer then with the constant threat of nuclear war. And yet, they bring back such memories!

Colombia on 10m JT65

Quite late last night, HK6JCF (8601km) was spotted on 10m JT65 bringing the total to 3 South Americans spotted on 10m JT65 yesterday.

25 May 2017

Roses - NOT amateur radio

Our roses came out early this year. They look great at the moment but will be bare in a few weeks' time. Our garden looks good at the moment. The risk is muntjac deer will eat the flowers!

OFCOM reviewing 410-470MHz band

OFCOM is carrying out a strategic review of the 410-470MHz band. This is a busy part of the spectrum in the UK and others want access. The 70cm amateur band is here and under pressure. At times, it seems devoid of activity. We have secondary access only. Use it or lose it, especially as OFCOM derives no revenue from the amateur service.  It would not surprise me if we end up with fewer frequencies at 70cm or we find our band shared with more users.

See http://ofcom.createsend1.com/t/\ViewEmail/i/3E3A949980CE1596/59D1BD3EA2F08127C67FD2F38AC4859C

10m JT65 today

In view of the successes with this band and mode yesterday, I have returned to 10m JT65 this morning. There is already widespread Es on the band and I have been spotted all over Europe already and this is boding well for the rest of the day. It would be good to be spotted in South America later.

UPDATE  1240z: So far 13 unique stations have spotted my 10m JT65 throughout Europe. Plenty of Europeans spotted here. I assume all this is Es. Nothing yet from outside Europe, but I am hopeful!

UPDATE 1604z: The first South American spotted on 10m JT65 is LU4HOQ (11342km) near Corduba. There is good Es in Europe, so I am again wondering if this is Es linking into TEP?

UPDATE 2010z:  So far, just 2 South Americans spotted on 10m JT65 this afternoon and evening. No-one has spotted me in South America on 10m JT65 today.

UPDATE 2110z: Well, it looks like just the two South Americans spotted on 10m JT65 today. I shall leave things running in case there is any Es in the night or early tomorrow. Again, like yesterday, my own signal was widely spotted across Europe, but not beyond.
