10m WSPR yesterday

10m unique WSPR spots yesterday
Quite a productive day on 10m yesterday with both Es and F-layer DX about. Best DX spot of my 2W was from FR1GZ on Reunion Is. and my best spot was of CX2ABP (11127km) in Montevideo, S.America who uses 5W.

This morning I have returned to 6m but G4IKZ, my faithful local reporter is not on!

Back on 10m again for an evening look

CX2ABP(11127km) in Montevideo (GF15wc) has just been spotted here at -25dB S/N on 10m WSPR even though propagation is supposed to be "poor" and he is using 5w.

10m really is my favorite band of all. Propagation supposed to be "poor" yet here is a South Anerican 11127km away on QRP! Now he is -21dB S/N and getting better!

UPDATE  2015z:  Weak highly Doppler shifted signals near the bottom of the WSPR band suggest there is some 10m GDX about too.  With luck, this may decode before too long? It needs a period with low Doppler.

UPDATE 2050z:  CX2ABP has now been spotted 4 times in the last 38 minutes and he is now -18dB S/N which is 7dB stronger than at first. Again, it may be just co-incidence but his best signal corresponds with when Doppler on his signal is lowest. It is as if ALL stations with any drift or Doppler are best when Doppler (or is it drift?) is lowest.

UPDATE 2111z::  Nothing seen since 2038z, so I suspect the band has died out for the day (or the software has ceased working again!).  Maybe I should go back on 6m looking for GDX again? I'll leave it on 10m for another 20 minutes just in case.

UPDATE 2132z:  Gone back to 6m GDX hunting.  All quiet here so far this evening. 

A morning on 10m

For a change, this morning I went on 10m rather than 6m. I had to disconnect the antennas early on because of a passing thunderstorm, but these are the results up to now with 2W out.  Basically a fair scatter of 10m Es WSPR spots given and received from across Europe. No DX from outside Europe seen (yet).  Hopefully will see some South Americans later.

Sunspot count today is 132 (quite respectable) and 20-30MHz propagation is "normal".
10m unique WSPR spots (2W) this morning


Southern Europeans are exchanging WSPR spots with S.Africa (TEP?) at around 8400-8500km, but N.Europeans are missing out.

Disappointment on 474.2kHz last night

After a promising start, last night was a damp squib on 474.2kHz WSPR with just 3 unique reports of my signal and all of these from people who have spotted my 5mW ERP before.
474.2kHz WSPR spots overnight with5mW ERP - disappointing
I have now returned, again, to 10m WSPR with 2W ERP. Until I extend my baseline on 474.2kHz, I think there is little new to explore on MF.

10m WSPRing again

This afternoon I have returned to 10m WSPR. There are lots of transatlantic reports of my signal, as well as reports of my 2W signal from Russia and Brazil.  Not sure if it is a Win 8.1 issue or just the V2 WSPR program playing up but I seem to be NOT uploading spots I see at my end. Perhaps the internet service is very weak in my shack?

UPDATE 1545z:  Restarting the program and re syncing the clock fixed it. Anyone know how to change how often the PC clock is sync'ed to internet time in Win 8.1? I need to increase the frequency I think. I don't even know how to find the control panel in Win 8.1 !

6m update

No TEP sadly but I did spot G6AVK at 78km on 6m last evening at -25dB S/N. This is a strange distance on 6m.  The -2 drift is almost certainly aircraft scatter, quite a common issue with inter-G paths on both 6m and 2m. It often makes decent signals not decode-able.

I do have a 0.5ppm TCXO fitted (it belongs to G3WKW) to the FT817 which helps minimise drift especially at VHF.  I plan to stay on 6m for more tries with TEP/Es today.
