PS: Maybe even Paul can find something. I remember last year we tried to see a trace on Paul's side, on 2970 Hz when i run 3 kV for 7 weeks or so. But now we saw and know the propagation challenge on

Hi Paul, Markus, thanks for the good work. It is interesting to see the combioned SNR building up in these very noisy days. On a quiet winter day we could decode the message in a single day maybe. If

PPS: Sorry, i was wrong. Stacking 2 days means (up to) 3 dB. So we need 16 days for 12 dB. About 8 months to reach DL0AO. That's maybe a bit much. I need more power... Am 28.08.2017 12:29, schrieb DK

Hi Stefan, > Maybe, can i ask for a 424 uHz spectrogram from W and EW? Here you go - the DL0AO grabber now has a 970 Hz spectrogram below the other narrowband images. Unfortunately the low frequency
