Passive monitoring of a NXDN48 Trunking System

[CqDx]

HI all,

I have experience and somewhat success in monitoring a relatively quiet Connect Plus system locally by using passive method and would like to know if I can do the same with a NXDN48 Trunking System on a NX5300 radio. For example, this is how I set up my XPR7550 radio:

Group List
Group Call ID 1
Group Call ID 2
Group Call ID 3

f1 slot 1
f1 slot 2
f2 slot 1
f2 slot 2
f3 slot 1
f3 slot 2

auto scan enabled on all six frequencies so whenever any Group Call IDs matches the Group List, the radio will pass audio.

Thanks in advance.

If it is a true Kenwood NexEdge system, then no.

NexEdge systems tag the packets with a bit that says it's from a trunked system. Unless the radio is properly programmed as a trunking subscriber -AND- the radio is activated in the system by the system administrator, it will not work. It will not decode audio.

An Icom radio may or may not do it. I've never tried. I've heard rumors about it working, but never confirmed myself.
A scanner is your best bet.

They indeed do. Can post a video proof if necessary. Can even filter talkgroups.
