    P25/Kenwood-Viking Over the Air Alias

    I am looking into the possibility of over-the-air aliases being displayed instead of unit IDs across our Viking VP5000s and VM5000s (some NXDN Kenwoods as well). Currently, we have unit IDs and all mobile/command staff listed within subscribers. Which is more painful to change, hints why we...

    SDRTrunk SDRTrunk Conventional P25 Not Unmuting on Most Calls

    I am running v0.5 alpha 6 and have not had any issues when monitoring various trunked systems, but with conventional C4FM SDRTrunk keeps missing unencrypted voice calls. The odd thing is that the decode is great, very little sync loss reported, and the NAC, TGID, RID, and Algo, are all correctly...

    Hazard PD Encryption Question

    I noticed that Hazard PD is listed as fully encrypted on the database on a frequency of 155.415. However, I have been hearing P25 traffic on that channel (with the matching NAC 002) a lot tonight. That being said, I live in Bell County, so I am not receiving it too strongly. It sounds like how...

Thinking I would get into scanning, I bought it off of him, because I liked the idea of having a digital scanner on the cheap. I'm trying to program the (photo) attached frequencies...

    P25 Conventional System

    I'm wanting to set up a Motorola Quantar as a P25 repeater with multiple talkgroups for our FD. My thought was to set up a talkgroup for each district. Each talkgroup would have the same NAC but different TGID. We will be running XTS2500 VHF / XTL2500 VHF units on the system. One drawback is...
