MSCOMMNET Non-Trunking Sites

[BlackSheepDue]

I traveled to Greenville for the second time recently and lost the Garland site about halfway between Dover and Greenville so I decided to look at what the next closest site was. Turns out it is Big Moose Mtn which the database lists as a conventional or non-trunking site. Are these entirely separate from the trunked system or are they at least patched into zone 3A? Also I assume I program them as P25 conventional personalities and not into a trunking system?

My observations from when I was in Greenville in September:
The solar-powered site on Moose/Squaw Mtn in Greenville seems to have 160.140/$80E as a 'primary'; it's usually carrying Zone 3A/TG 731. 160.350/$80E seems to carry traffic from other TGs; I heard some 1700 units talking on this freq. (I don't remember which agency uses the 1700 callsigns and I can't find it in the wiki. Fire Marshalls maybe...?). Nothing heard on 154.680/$80E, I would guess that this is used if the first 2 freqs are busy. I'm at a loss as to how the system can deal with affiliations and direct radios to specific frequencies without a control channel, but it seems to work somehow. The only frequency at the Big Spencer solar-powered site (172.775/$80E) was carrying Zone 3A traffic.

Thanks that's definitely helpful. Did you have each of those frequencies as conventional P25 personalities or were you using a scanner with the "1 frequency trunk" option?

My guess would be that they are configured as One Frequency Trunk sites and the controller performs the control channel functions. Again just a guess.

That was my understanding as well. I threw them in my apx’s as conventional personalities. Not sure how they would handle 1 frequency trunking.

Just as P25 Conventional. I've heard SP Augusta/TG 721 on 160.140 in the past as well.

Perfect, thanks. Zone 2A coming up on 160.140 make sense as Big Moose is so close to the zone 2/zone 3 boarder.
