Let me preface this by saying that I have no experience with Raspberry Pi's, Linux, OP25 or SDR radio until just today. LOL - Thanks to a couple of excellent guides including the OP25 for dummies guide I am successfully decoding P25 Phase II audio on a Pi 3B with an old NooElec R820T dongle that I purchased years ago. My next step will be to setup streaming the audio as my ultimate goal with this project is to replace one of my streaming scanners with the SDR to solve the simulcast issues on my live audio broadcast.
I'm slowly working my way through this but there are a couple of things that concern me right now:
1 - I am using a q value of 46 when launching OP25 to get my dongle on the right control channel frequency - It has been running now for several hours and it's decoding properly but this number seems way too high to me based on what I've seen in tutorials and the minimal knowledge I have. Is this a problem?
2 - I am unable to launch gqrx on the Raspberry Pi. I have installed everything correctly as far as I can tell but when I try to launch from a command line or double clicking the executable it does nothing at all. No error or anything, it just never launches. So far I have not needed this but it seems that it could be useful. Is this a problem?
I am sure I will run into more issues and questions.
Thanks for any help,
Brandon
