Having a stupid morning. I wanted to check the output from my new transverter off air so wired up the RSP2 and CubicSDR on the Mac. I did all this yesterday when I first installed the transverter but wanted to check again now I’ve been stuffing FT8 out of it for a while.
Good peak, nicely on frequency. No modulation! Ah. Ok, check everything. No change. Try QSYing and SSB. No modulation. Power off and on. Nope. Shout at the rig. No change.
Set CubicSDR to SSB… ugh! All fine of course, it defaulted to FM… as it did yesterday but today I forgot!
