Antarctica heard on 28 MHz - 1st Feb 2022


Tuesday 1st February 2022: While conditions on 28 MHz weren't as good as the 31st of January, the 10m band still opened to Australia. I was listening on WSPR all day and the most interesting signal for me however was the German Antarctic research station DP0GVN.

These are the WSPR decodes from Australia & Antarctica...

If you examine the signal strengths then you'll notice that they are all down down in the -20dB to -29dB region i.e. they're buried in the noise and well below what I could hear by ear.

Even if the signal is really weak, there is still a bit a of 'wow' moment when Antarctica appears on the screen on 10m.
