I have installed op25 but I get a no attribute “get gain names” error… I was I guess completely unaware that op25 doesn’t have a gui. What programs can decode p25 phase 2 that can run on a raspberry pi 3 that have a easy to navigate gui? Thank you! Please help

So I’m trying to host a stream and calls with two dongles on a Pi, is this possible? Calls are separate from an audio stream correct? Would be a P25 Trunked system. Thanks

I purchased an RSPdx several years ago, and was using SDRuno on Win10. It worked great! I made the mistake of allowing my Win10 machine to access the internet, and was suddenly being forced to do things by Microsoft that I really didn't want to do! So I decided to dump Win10, and installed...

Hello everyone. I have a thing called LibreSDR. As far as I understand, it is something like a clone of ADALM-PLUTO from Analog Device. I have never worked with such devices, but the opportunity and need to use it in my work arose. As I understand it, this thing can scan a given frequency and...
