Hello Stefan, Yes, it should be very well possible.The brain of a skilled CW operator can simulate a filter with a bandwidth of about 50 Hz. So, to achieve a better SNR, a narrower filter is called for. With a bandwidth a 10 Hz and a keying speed of 10 wpm, it should work. No QRQ though, I'm afraid. Unfortunately I have no space for a LF antenna.... On an other note, WSPR is excellent for overnight T/A propagation study.Just following WE2XGR/6 this week has been an interesting demonstration of night to night variation in propagation. It also shows that for long range signals the much discussed deep fading problem is not so severe as on closer range signals. 73, Roelof, pa0rdt |
