XG-100 Basic programming for P25 800MHZ

[stonek554]

Would anyone be able to provide me with basic information on how to set up a P25 trunked 800Mhz system on the radio for receive only operation? I use VHF and UHF (Med Channels) for my primary work, but would like to monitor the trunked system in my market also.

I am also interested in learning how to program my xg-100 for recieve p25 only.

The trunked systems you refer to are probably similar to or exactly the same as those used with Motorola equipment. That being the case, unless the system administrator permits you to do so you will not be permitted access to the trunked system. If you should acquire the system key and your radio is not authorized there's a good chance that the sys admin will stun/kill your radio which would mean it has to back to the shop for a reset and you'll be asked what/how this happened to your radio, plus it'll cost you money for the fix. If you're not authorized to monitor a trunked system using a transceiver get a scanner and stay out of trouble.

While the Unity does support receive only talkgroups, it also requires registration/affiliation before it will unmute. Unless the radio is allowed on the network, I don't think I would risk such an expensive radio getting inhibited.

The radio WILL receive the system WITHOUT registration.. It will listen to the CC and start receiving as soon as it hears a talkgroup thats in your scan list.. That is a wive's tale that sales folk used to tell the customer but in fact it is not true.. As for the "System Key" needed to program the radio... Not so with a TRUE P25 radio.. Harris is a TRUE P25 radio... You only need the Programmer / RPM software, cable and the system info in order to program the system..Only the Bat wings needs a key on P25.. Kinda kills the meaning and reasoning for an open architecture and interop operations..

I have programmed many Harris radios for receive only with NO transmit function enabled

Our demo radios refused to unmute until we allowed them to register. This was a few firmware versions back, so this behavior might have been a "bug"

As for system keys, its not just Motorola requires a system key, EFJ, Kenwood, Thales and most others require a key. In fact, several systems (including one large statewide system in the southeast) that are looking to put harris radios on the network are requiring them to implement a system key before authorizing the radios on the network.

RPM has a few wide-area P25 systems in it that require a key to program. The ARMER system and another I can't think of will ask for a license key to be entered if you enter the correct WACN/SID. So there is something in place similar to Moto but it appears to be by request only.
