Astro conventional Talkgroups

[katt02]

Hi all,

I was playing around with the software for my xts3000 a few days ago and I noticed that I have the option to set up talkgroups in conventional astro. I am somewhat confused by this because I am pretty certain talkgroups are used on a trunked system. Anyways, is anyone able to explain why talkgroups in conventional exists or how they would be helpful?

thanks, Katt

Talkgroups do exist in P25 conventional. It's only 1 talk path (one active conversation at a time), but you can split the traffic up with talk groups on a conventional channel. Sort of like putting people on different PL tones.

ok interesting. Do these talkgroups need to be programmed the same in each radio or can I set up only two radio to have a talkgroup and the rest use conventional without talkgroups?

All p25 conventional uses a TG, often times just defaulted to 1. Whether others can hear other TGs depends on the squelch setting.

Wouldn't just using a different NAC on the same frequency accomplish the same thing?
