Hello Dave and Alan, Really impressing how little power is needed to travel 220km at 136kHz. The 360mW needed for the CW copy should be no more than about 1mW ERP I guess, QRSS60 does the job with no
Dear all. I did some tests today with Alan G3NYK at about 220km distance, to compare the performance of different QRSS speeds under real band conditions. How much better is QRSS60 than QRSS10 or QRSS
