Thanks for the information on tg 777. I assume that if you enter contacts for the tgs you want to scan on tgif and then create channels, then create a zone for tgif with those channels, and enter these channels in a receive group, then listen on 777 one will hear all the talk groups in the receive group list and in that zone?

If you use promiscuous mode, will one hear all tgs on lets say Brandmeister or if you have a zone set up for tgif will you only hear the tgs on the tgif network? Is that one other way to use 777? Which of the two ways is best to use the new 777 tg promiscuous mode or programming receive groups?

I am trying to understand the difference between programming receive groups and using promiscuous mode.

Again, thanks
