Hi MF, Could someone run WSPR on MF for the next few hours? I'm again checking my MF station in the garden and would like to make some SNR measurements between the main and /p QTH. 73, Stefan/DK7FC P

Wow, thanks for the very high activity. Special thanks to PA0A who sent a signal that was strong enough to make the daytime groudwave distance. Unfortunately i had to go before the band opened becaus

That is crazy, it seems nearly everyone who has a transmitter and antenna is on air now! On the map i just see coloured lines :-) More, more, we need everyone! :-) 73, Stefan, stunning Am 14.08.2014

Hi Warren, Cheap devices for 3 EUR (or $) will do most jobs very well. But it may be worth to spend some more money. 192 kHz sampling rate is available for a low price. But you may first try to insta

Thanks Mike. Obviously my TX power is about 6 dB lower because of a temporary metallic construction near the antenna, which brings my variometer to the lower end, i.e. the maximum resonance frequency

Hello Luigi, That is very nice! Good luck with your QRP transmissions. For you it's easier to add another 6 dB of power to your signal than for me :-) My WSPR-15 LF RX is running 24/7, so maybe you w
