Thanks folks for all the tremendous help on my other posts, lots of great info to consider. And a very happy New Year to all.
As I've mentioned before, we are running 3 XPR 8400 repeaters connected via IPSC, supporting 21 radio users (a combination of XPR 7550, SL7550, and XPR 3500). We have been granted 3 repeater pair frequencies from the FCC on the business spectrum. We have two timeslots, with 5 channels on TS1 and currently 1 channel on TS2.
I would like to make better use of simplex/Talkaround channels for our system, but do not fully understand how they function. The goal would be to increase the number of simultaneous transmission s that can occur, so that, for example, our facilities staff isn't competing with our audio visual staff. Will simplex channels help with this? Effectively would love to have a dedicated simplex/Talkaround channel for each department that has radio users. We have excellent direct mode coverage in our primary facility, the repeaters help to cover two remote, relatively unused locations... direct mode would provide sufficient coverage under most circumstances.
A few questions...
1) is there any functional difference between enabling Talkaround on an existing repeater channel and creating a stand alone Simplex channel?
2) All my channels on ts1 share the same RX and TX frequencies. If I enable Talkaround on multiple of these channels, will they conflict? Would this still prevent multiple simultaneous transmissions?
3) Our dealer programmed 3 dedicated Simplex channels. Is it possible for me to add more? How would I determine the frequencies?
4). Is it possible to scan or listen to repeater channels while operating on a simplex channel?
Any thoughts or resources would be greatly appreciated.
Thanks!
