    SDRTrunk How to start over with SDRTrunk?

    Hi all, I've been experimenting with SDRTrunk, and I've gotten it to work all of once. When I first installed it and got it set up with an Airspy R2, it was successfully decoding the P25 Phase 1 system I was trying it out with. However, I think I tweaked something somewhere, and it now refuses...

    SDRTrunk Linux Headless JMBE + Vector Calibration?

    I figured it might be more helpful posting here than the Github issue tab but who knows, maybe I'll have to do that as well. I'm working on spinning up a raspberry pi 4 with an RTL v4 I have laying around to test some signal reception at a buddy's place. I've copied the settings from my current...

    FCPS Bus Systems/Frequencies

    Ever since getting into radio, I have been curious about what systems FCPS uses. Specifically, I always hear radio chatter on my school bus, and have been interested on what they are saying. I had touched on this a tiny bit last year, but now I'm set on actually getting it to work. Please keep...

    System requirements for 8 SDRs fed into SDRTrunk

    I’m in the process of researching moving my feeds from simple scanners to using SDRs. I know 8 is likely overkill but I have a 8 port multi coupler so I figured why not fill them with SDRs considering they are cheap. Everything will be mostly analog, with some P25 conventional (all public safety...

    SDRTrunk - Fine Tuning

    Greetings all - My county has gone digital/P25, and I don't want to assign my SDS-200 to Broadcastify duty. (My PRO-2096 was doing this just fine until they went completely P25.) So, I'm looking at SDRTrunk to handle this function. I've got SDRTrunk installed, and I'm fully aware of the...

    SDRTrunk only shows control after a bit.

    I'm very new to the world of SDR, and I am using a nooelec sesdr smart, but the problem I'm having is that every time I start the channel, it will play perfectly for about 30 seconds, and then it will stop and the only channel in the now playing will be the control. The only way to fix it is by...

    SDRTrunk Missing calls - Site Review

    I've searched on the forums to find a solution to two issues I've been having with a site I added. First issue was missing calls when they key up back to back so I added an additional dongle to hopefully fix that issue. The second issue was the calls would sometimes sound garbled and like it...

    New to radio and am trying to understand what my setup is actually doing. I have an RTL-SDR and have some success decoding P25 with SDRTrunk and Boatbod OP25. If my understanding is correct, SDRTrunk can monitor the entire available bandwidth around some frequency of the SDR dongle and if...
