2m FT8 activity contest

Starting at 1900z is the RSGB organised 2m FT8 activity contest. At the moment I am RX only, although I might try TX with 2.5W FT8 with the big-wheel omni later.  So far, 35 stations in 6 countries spotted after 7 minutes!

UPDATE 1940z: 74 stations in 7 countries spotted. 1 QSO just now. RX only again as it is too crowded!

UPDATE 2110z:   96 stations in 9 countries spotted on 2m FT8 RX this evening and 3 QSOs. My signal was spotted by F1FPL (345km). Now QRT. Quite pleased with just 2.5W and the omni antenna.

Summer Saturday - NOT amateur radio


This was Salcombe, where I come from in South Devon, on a summer day many years ago. 

10m FT8 RX

A few moments ago (0955z), I turned on my 10m FT8 RX. As I had just turned the electricity off whilst I changed a bulb in the bathroom, there was no internet, so no spots were appearing on PSKreporter.  Locally, I was spotting several stations.

UPDATE 1024z:  37 stations spotted and on PSKreporter. Most are single hop F2.

UPDATE 1411z:  172 stations spotted.

Stations spotted today
UPDATE 1744z:  476 stations spotted. QRT soon.

Dalham near Newmarket - NOT amateur radio

 


This is a village not far from us. As you can see, there are lots of thatched cottages. It is very beautiful.
