SDRTrunk Setting up sdrtrunk to decode trunked NXDN

[ronenp]

Hi there
the New nxdn decode works well
when i put the control channel in the frequency tab it decode that it is control channel but donr show any voice conversation and of course dont follow voice calls
is there a way to follow voice conversation like it does for P25 ?

Thanks Forward

For starters, what system are you trying? Do you have all freqs programmed? What's your signal look like and how is your PPM? Post a pic of tuners tab with spectrum.

Does the system work in your dsd neo?

I'm also trying it on an NXDN 4800 system (Florida FleetTalk). It appears to be working, I am seeing a strong control channel, and I see call grants and other events, but there's no audio. Same system works fine in DSD Plus Fastlane.

I get audio on nx48 systems but only a few radio aliases populate. Tg name are not populating. I imported the system from the db.

I'm on the 07/13 release. Control channels work, custom aliases mostly work. Calls come in but the audio is very distorted and loud and sometimes calls will drop out. Tried different gain settings and nothing changes. Also on an NX48 system. The initial call initiation message will show the TG alias but "Group Call" messages wont show it.

Unless it's a DFA system, you are going to need to know all of the frequencies that are part of the site that you are monitoring as well as their associated channel IDs / LCNs. If you are definitely on a control channel, it should give you information about the system such as a network/system ID and a Site ID. And, well, if it doesn't show any voice calls, then nobody is talking

It's not going to be programmable like a P25 system (where you only need the active control channel most of the time) unless it's an actual trunked NXDN system using DFA (direct frequency access). Most are not DFA.

I'll give it a shot later today. I have our local NXDN RAN mapped out pretty good.
