GB3NGI heard on 144 MHz with an indoor antenna...

During the EI 2m activity period on Tuesday evening, I had a tune around the beacon band and used the PI4 software to see if I could see any faint signals in the waterfall. To my suprise, I could faintly see and hear GB3NGI which was 385kms away...


Considering I was just using a vertical Slim Jim in the attic of the house, I really wasn't expecting to hear anything.

I looked up the beacon website https://www.qsl.net/gb3ngi/ and found that the signals were alternating between CW and JT65b. As I had never used JT65b before, I had some trouble getting the WSJT-X programme to decode the signals.

After doing a bit of research, I changed some settings on the programme... Settings > General > Enable VHF/UHF/Microwave features and then used the settings in the graphic above. It now works ok and I can see the decoded signals.

Thanks to G0MJI and the screenshots on his website which make things a lot clearer.
