Can't hear conventional (simplex) P25 digital channels #1067

Open nic-hanna opened 3 years ago

nic-hanna commented 3 years ago

I've got SDRTrunk set up to listen to a Phase 2 trunked network, and works great. Now I want to listen to the simplex channels.

I know the frequencies and it shows up on the waterfall when someone is transmitting but regardless of if I choose P25 phases I or P25 phase II individual for the channel, it doesn't make any noise, but I see it on the waterfall.

Any ideas of how to listen to digital simplex channels in SDRTrunk?

Are you sure these calls are part of the same P25 network you're monitoring via the Control Channel? Are you sure it's digital radio?
Have you tried listening to these calls on SDRSharp to see if they are plain analog radio?

I'm sure they are part to the same network, I know they are digital because I've listened to them on my HT and SDR Sharp and it isn't analog.
