When I was hunting for more POCSAG signals with SDRsharp, my Windows 10 computer locked up. I had to do a forced shutdown and then it wouldn't restart. It took me 4 attempts to do a restore to an earlier date; seems to be OK now.

So I switched to my SDRplay RSP1A SDR with SDRuno software. My signal is also weak and the high noise level on VHF reduces the SNR of the signal.

I also found some on UHF:

Oh damn. That's really weird.

do you think that 45db was the best?

Yeah, I couldn't use my computer until I fixed it. It happened when I stopped the signal in the SDRsharp software and then tried to turn it on again.

My guess is yes, but you don't show the signal in the spectrum scan during a transmission, just the signal in the waterfall after the transmission.

I try to show the signal in the spectrum analyzer scan during a transmission AND the signal in the waterfall below it. That's when my computer got locked up from ON and OFF switching with the Play/Stop button. At this point, I don't want to do that again with the SDRsharp software. I might not be able to fix my computer again.

Use whatever gain setting gives you the best POCSAG software output.
