19th June 2021: After getting an email from Vernon VE1VDM, I fired up the Spectrum Lab programme and managed to grab TWO trans-Atlantic QRSS signals on 28 MHz...
(QRSS are morse code signals sent very slowly over a period of several minutes. This is an analogue method of reading signals that are buried in the noise)
It was probably the strongest capture I've got to date of VE1VDM and the first time I've managed to capture N8NJ. His power was 2-watts.
N8NJ is also the longest distance QRSS signal on 28 MHz I've captured as well. His power was 1-watt.
These are the WSPR reports around that time so you can compare what the QRSS signal looks like against the WSPR signal report.

VE1VDM at -13 to -15dB was at a level which would be barely detectable by ear. It's too weak for CW sent at normal speed.
N8NJ at -20 to -24dB was buried well into the noise.
In truth, there's nothing that remarkable about hearing Canada or the USA on 28 MHz during the peak of the Summer Sporadic-E season but it was still nice to get a screen capture of two low power stations from the other side of the Atlantic.
