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 17th of October, I heard AA7US in Arizona during an F2 layer opening during the afternoon.
The QRSS signal can be seen at the top of the graphic above. I also heard AE0V who I had heard earlier this year.
QRSS is a mode where a morse code signal is sent very slowly over the space of several minutes allowing very weak signals to be displayed on a waterfall display.
G0MBA and G0PKT were probably via F2 layer backscatter to the west.
The path from my location on the south coast of Ireland to AA7US in Arizona is just over 8000kms which was probably 2-3 F2 layer hops.
John, AA7US was using 1.5-watts from a QRPGuys AFP-FSK Digital Transceiver III kit into a horizontal Hamstick dipole mounted about 5 metres above ground on a mast on the back of an RV.
In summary... That brings the QRSS tally so far for 2024 up to 24-callsigns & 10 DXCC.
