2m FT8 QRP

It is now 1002z.  For about 10 minutes I have been on 2m FT8 QRP using my 2.5W and the big-wheel omni antenna. So far I have been spotted by 11 stations already with the furthermost being G7RAU (461km) in Cornwall.

I am still puzzled by WSJT-X RX with Windows 10 and the SignaLink USB. At times it works whereas at other times the waterfall is smeary and I get no decodes. At first I thought this was just the first few minutes, but I have seen this be OK then not.

UPDATE 1434z:  Spotted by 18 stations in 3 countries and I have spotted 44 stations in 7 countries today with furthermost OZ1CCM (796km). Just turned TX on again as it was turned off.

Is your Signalink USB modified as per this suggestion?


Especially for VHF the USB power supply is also used for the analogue electronics which induces noise onto the Rx signal and this varies with the computer USB activity.
