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? 73 Fer IW1DTU
