20m FT8 RX

For a total change I am on 20m (14MHz) FT8 RX.  My antenna is very poor and I cannot get a good match. Even so, I am spotting JA stations.

Within an hour on 20m FT8 RX with a useless, low, antenna!

UPDATE 1252z: Too easy! Spots on 20m FT8 RX today so far. Remember my antenna is low and not even resonant!

UPDATE 1515z: At the moment, Indonesia is the best DX spotted at 11977km. Also, west coast USA is being spotted but nothing from Africa, Australia or South America. I am unfamiliar with 20m, so I do not know the best times for these.

14MHz WSPR

Overnight, for a change, I decided to give 14MHz WSPR a go, although the PC decided to install updates at 0300z and turned off the computer! At breakfast I restarted everything. Stateside late at night and Europeans now.   Will go back on 10m shortly.

UPDATE 0951z:   Now back on 10m and 630m (472kHz)

14MHz to Australia - Adelaide

This evening, I went on 14MHz WSPR with a couple of watts and was rewarded with a spot by VK5AK (16224km) just outside Adelaide, Australia.  Apart from this spot and K9AN (6505km) the other spots, so far, have been from Europeans and of Europeans. I shall stick on 14MHz for a while longer.

14MHz WSPR this teatime (2W)

OXO on 14MHz

An OXO transmitter on 14MHz

This afternoon I decided to build a 14MHz OXO transmitter. As is often the case, I like to re-use old boxes and project parts, so the FETer box was photographed for posterity, then gutting and used for the OXO transmitter. In this version I did not go for full break-in and instead used a simple changeover switch, but added a push button net function to allow me to net the VXO without the PA being keyed. A small toroid in series with the crystal allows about 15kHz VXO range around the 14.060MHz QRP frequency. I used a 2N3904 for the oscillator and 2N3906 for the keying transistor and a 2N3866 for the PA, but may change this for 4  x 2N3904s in parallel for lower cost. My output is a little low at around 500mW.

It works fine with reverse beacon reports from Iceland and Slovenia and a nice 2-way QRP QSO with IK2RGV who was running 5W.

The OXO really is a classic circuit: you just build it and it works.  Another version is on the QRPkits page.
