I was thinking the same thing myself. When the band is open, the County 9-1-1 Dispatchers must go crazy over all of the radio traffic. In fact, I have actually heard Outagamie County on 154.250 MHz, here in my county, when I have the PL turned off on my scanner. So I am sure they hear numerous other fire departments without a PL tone on their radios.Thunderbolt - According to the RR database, their entire system is CSQ only. (Carrier Squelch - no CTCSS tone or DPL). I verified that some time ago during their morning radio system test by monitoring their frequency on my service monitor connected to an outdoor antenna.
That's interesting, because there are approximately 9 other agencies on that frequency within reception range of Outagamie County. That must be a real 'joy' in their dispatch center on days when the band opens up a bit... LOL.
Actually they had a UHF band (450-460mhz) linking system between thier towers and the dispatch center now it is all microwave I believe. And there are actually 6 different mobile input PL's for the input frequency of the repeater. 6 repeaters and 6 inputs might help with location determination also.I don't believe the dispatch centers hear any of this as they have some sort of UHF linking system between thier towers and the dispatch center thus only traffic on the local towers is heard. The Outagamie towers have 5 different mobile input PL's and each has a UHF link to the consoles.
