it does the same here TN tower then anitch then gladeville then whitehouse
I have a GRE PSR-500 and an RS PRO-197. If the Whistler scanners handle multisite the same way as my scanners, then:
a. in the TSYS object, set MULTISITE: to STAT
b. then set Check ALL CC based upon your preference
If you have the option to Check ALL CC, what this does [when enabled] is poll every control channel during each time it scans that trunked system. If you DISable Check ALL CC, then it'll during every complete scan cycle it will poll a single CC for the most part.
To use my setup as an example, I have Multisite set to STAT because I don't want it to lock onto a site based upon signal strength. I want it to attempt to find a signal on all CCs. I monitor from home. And I have "Check ALL CC" disabled, so it doesn't spend a ridiculous amount of time during every scan interation polling every CC on that particular system. I have another system programmed in and some conventional channels. I wanted to avoid missing conventional calls and calls on the other system.
If you only had one system programmed in and nothing, or were only scanning one system actively and nothing else, then enabling Check All CC would make sense [to me]. But if you are scanning multiple systems / conventional lists you want to make sure those are given a fair chance to be heard so you wouldn't have Check All CC set on the multisite system.
If I have five CCs in a multisite STAT system with Check All CC disabled, in the first scan iteration it stops on the first CC and checks for activity -- waits a second and moves on to other items to scan. Then when it comes back to that system, it checks the next CC for that system, waits a second or so to see if there is activity, and then continues scanning.
Sorry I didn't iterate that too well. And what I've said might not even apply, depending upon how the TRX scanners are set up to handle multisite. I'm just assuming they have a "STAT" option.
Even when I'm mobile I run Multisite STAT.
