PCWIN (Tucson regional fire dispatch) A4/A5

[Maxagonzales]

Hello all,

I live in NW side of Tucson Marana to be exact at Twin Peaks and interstate 10. I think I have heard some changes to NW simulcast. Lately I have been hearing traffic on A4 South on NW simulcast and also I have not been hearing A5 East. I was wondering if A5 East is in contact with the Nw simulcast does anybody know about this?

A4 and A5 are always heard on Simulcast B, and are also heard on other sites as needed by system users. In other words, if a radio affiliated with the North Simulcast site is monitoring (or scanning) A4 or A5, they will pull A4 and/or A5 onto North Simulcast. If no radio affiliated with the North Simulcast site is presently monitoring (or scanning) A4 or A5, then you won't hear those TGs on North Simulcast.

So how about the PSA for the academy channels there not listed on rrdb of any radio simulcast

I am not an expert, but at this moment on simulcast B talk groups A4 and A5 are combined with same dispatcher giving out the same information on both talk groups. This might have something to do with the North simulcast. This is a common situation with the City of Tucson.

Thanks for the input, yesterday i was listening to A4 in simulcast but the radio traffic went away then came back again a few minutes later, what I am trying to get at is get all readable channels to be listened to some how on NW simulcast

On North Simulcast you can only hear, at any given time, the TGs that are active on that Simulcast because a system user affiliated with that Site is listening to (or scanning) that particular TG or a TG patched to that TG. The system is designed for the needs of system users rather that passive scanner listeners. Sites don't carry traffic for which no subscriber affiliated with that Site is monitoring or scanning. Think of that adage about a tree falling in the forest - a transmission simply will not be carried over a particular Site for which there is "no one there to hear it". This is why you can hear all sorts of unusual activity on Sites from time to time.

I sometimes (but rarely) hear Ajo EMS on Simulcast B. I assume a subscriber in Tucson decided to listen to that TG or an Ajo ambulance transported into the Tucson area, perhaps from the T.O. reservation and is affiliated with that Site while monitoring that TG.
