2024 10m QRSS Challenge: - VK4BAP in Australia 28th Feb

As part of a challenge for 2024, I've decided to see how many QRSS signals I could capture on the 28 MHz band during the year. On the 28th of February, I noticed VK4BAP Queensland, Australia.

For my first attempt above, I managed to get a positive ID on the signal. However, a very strong OH station from Finland just above using WSPR was playing havoc with my audio levels. I tried to adjust the volume as best as I could and managed some sort of screen grab.

Finland is just one F2 layer hop from my location on the south coast of Ireland and signals are usually very strong. The QRSS signal from Australia by contrast is just about visible in the noise.

It's a bit like waiting on the bank of a river and waiting for a fish to bite. I'd start to get a reasonable QRSS signal from VK4BAP only for the OH station to then clobber it! :o)

Eventually, the timing got to a stage so that the VK station started just after the OH station had finished transmitting and I managed to get a reasonable if somewhat weak screengrab.

My target at the end of the day is to get a full screengrab of a signal which can be positively identified regardless of how weak it is.

The distance was about 16,070 kms and the propagation mode was via multiple F2 layer hops. There may have been some chordal hop in there as well. The time for the reception reports was about 09:00 UTC.

In summary... That brings the QRSS tally so far for 2024 up to 16-callsigns & 9 DXCC.

Addendum: Brian, VK4BAP reports that this was his first day ever transmitting QRSS. He was using 1 watt to a Moxon beam pointing to Europe.
