[amsat-bb] Still trying to decode NO-84

FINALLY!  I am not losing my mind.

Fer sees the same thing that I see on receive!  Multiple harmonics signals in the passband on RX!  Is that what it is supposed to look like?  I am expecting a single PSK31 trace like what I see on HF….how will multiple harmonics be decoded sing FLDIGI?  Sorry if I am wrong about this, but that’s what an overmodulated AFSK BPSK signal looks like on HF.

I am trying too to activate NO-84, 50w on 28.120 MHz with vertical antenna or dipole with FLDIGI (saw no difference, still weak), good downlink signal on UHF with SDR-14+SpectraVue as panadapter at 10.7 MHz, beacon decoded in FLDIGI,   my weak signal  sometime decoded, strong doppler on my signal despite I correct both with orbitron/wispdde using only fresh keps and GPS computer sync clock.

Any idea?
