I see from your file that you have location turned on. I checked mine and it was not set to my lat/long, and it was only I think 15-20 miles. I changed it to 50 miles, We'll see now if East County comes in. It's logical, but who knows?

I was on my 436 with stock duck in Lawrence Park the other night. Locked onto Urban Simulcast since that was the better signal. Could hear Fairview get dispatched to an ATV accident. Once they moved to WC Tac 1, I couldn’t hear anything until I moved to Countywide Simulcast. Would have thought you’d hear everything systemwide?

In most cases, talkgroups are only broadcast from the sites that cover the intended service area for the talkgroup's users. It cuts down on the load on the system, especially on large statewide or multi-state systems.

So if I'm in west Millcreek and can't ever hear East County Fire, it has to do with sites possibly?

The system may even be smart enough to know what site units 'tuned' to a particular talkgroup are hitting, if they were to move OPS to a TAC channel it may limit the simulcast to one site or the other.

Since my background is cellular and not LMR, I may be way off base but that would certainly increase spectral efficiency and I see no reason that it wouldn't be possible.

If the east site is simulcast, you may be in a better location--where one transmitter dominates the received signal.

That is weird because I am maybe 8 miles further west than Him and get the East County Talk Group fine....
It appears from the system map that Millcreek lies within the Urban Simulcast cell (city of Erie and immediate surrounds,) while farther west lies within the Countywide Simulcast cell that covers the county land area east, west, and south of the Urban Simulcast cell. If the East County Fire area of operations lies east of the city, it is probably covered by the Countywide Simulcast cell. The East County Fire TGs are likely limited to the Countywide Simulcast cell, unless some unit affiliates with the Urban Simulcast cell for some reason. In that case, the East County Fire traffic would be broadcast on both simulcast cells.

That's a possibility...I was looking for the map and remember the city cell came out west into millcreek I think. still weird because he gets the other county talkgroups ok...….

There are many variables that can affect what traffic is heard on what site. Running Unitrunker (or similar program) can help to visualize what is going on with the system. Ideally, you can run two instances of the program on the control channels for both sites and watch what is going on.

It going to take time to figure out which sites are normally carry what talkgroups.

Talkgroups can be program to go out over all or just site involved and can be blocked also however i doubt with such a one county system they would do that.

I've been keeping my ears on the hospital TGs, but haven't been hearing anything. Anyone getting activity on these TGs?

OK...now I'm hearing activity. I'll have to check my settings because I haven't avoided them, but they aren't picking up on scan...time to dig into my settings some more...
