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

0230 UTC pass, saw the bear claw PSK 31 waveform again. Anyone else able to see the PSK dowllink? I am seeing 7 parallel traces, almost like the transmission is overloading the receiver.
Attempting to attach the file to this email with a capture of what my SDR receiver is seeing...
On a positive note, APRS is working perfectly on NO84 even at low passes.
