I was thinking the same thing. When I saw squelch set that high and suggestions to go higher, I thought “Wait a minute, mine is set at 2. Do I have it backwards?” Also, I’m in Michigan and travel daily with the GPS feature running. I’ve found that with so many simulcast systems running, it seems that depending on which control channel a particular agency is using, it may be possible to pick up a department several counties away because the county I’m in or a county in between have overlap of frequencies. For example, if I’m in Montcalm County but happen to be in range of a Kent County site, I may pick up Allegan County through the Kent simulcast system. However, on other occasions I will be in the northern part of Allegan County but pulling from a closer Kent County site and not get Allegan at all. This can happen on both my SDS100 and my Unication G5. The only theory that I can come up with is that one of the department’s primary control channels has changed to an alternate, thereby not “hearing” the other department. If someone can confirm or deny my theory, I’d appreciate it.
