Hello! I am very new to SDR and am having some issues with OP25 & Raspberry Pi 4. Note, I have been able to configure and run SDRTrunk on Win10 with the hardware I have. I am not new to Linux console but it's been several years since I've used it.
Running Raspbian (buster) 5.4.51-v71+. Fresh OS install on new hardware less than 48hrs old.
I connected 1 RTL-SDR version 3 into USB of the Pi v4.
I ran a standard installation from this tutorial and this video.
I am able to run the start script command and OP25 launches. That's where the show stops.
I've played around with the sample sizes, the LTR and the -q options (-5 to +5) with no changes. The program will run and display "Allocating 15 zero-copy buffers" at the top of the screen. After a few seconds, I get the message "<log date/time> [0] p25_framer::rx_sym() tuning error +1200". Sometimes, the error says "+2400".
I am trying to decode the OKWIN P25 system in Tulsa, Ok. I am located 17mi from the Tulsa site and 6mi from the Coweta site. Being a multicast system, my Uniden 396XT has trouble with both sites. The SDRTrunk on my Win10 machine with [same] 2 RTL-SDRs connected works flawlessly on the Tulsa site. I am using the same Control Channel in my SDRTrunk instance as I am with the OP25 script. It simply won't lock on and display any information. I have not started setting up the talkgroups yet. Haven't been able to grab the CC yet.
Any help is greatly appreciated.
EDIT: Looking through my console, I so see "[R82XX] PLL not locked!" Also, with OP25 running, if I press 1 to see the gnuplot, the program crashes and will not run again until I reboot the machine.
