talkgroup 65534

[cg]

I have seen radios affiliate on talkgroup 65534. Is this a specific function rather than a single talkgroup? I have seen it on several TRS's (both 3600 baud Astro) and have never seen any activity on the group (other than affiliations).

Where are you seeing this? Talkgroups don't even go up that far. They end at 4094. Most software is coded to reflect this also. Bad decode I'd say.

I'd suspect that's "Uniden notation", i.e. decimal; I have hundreds of talkgroups over 4094 on many M systems in my area. Never seen 65534 though.

Ah, yeah, I forgot about decimal mode under Trunker (I never use it). But even in this case the affiliation would be 65520, that's unless the system is SmartZone and the connect tone is 8.

A majority of systems don't use TG4095 anyhow.

Wait, is this Trunker or T4Win? If it's T4Win I would ignore it as something got mixed to form a bad affiliation. Common with T4Win.

It is a Type II Astro Networked system being monitored with Trunker displaying in decimal mode. The radio ID indicates it is not one of the new digital radios. The digital talkgroups are all encrypted. It is Bristol CT (2e39)

Group 4095 is the group that designates sitewide or systemwide call. All non active radios will hear the call. System owners must specifically request this feature from Motorola, most don't. Even those that do, rarely use it.

The only place where I have seen it used is at chemical plants where it is used for major announcements and evacuation announcements.

I am also aware that some RF-modems affiliate this way when they are first powered on. I was told it was a harmless bug in RF-modem firmware. (For those that don't know, an RF-modem is a special radio used with certain Motorola software packages such as SystemWatch.)
