I was listening to the Hartford Fire Dept. Simulcast frequency (154.3100) today and I heard some weird tones go out. I should mention that I just mounted my 20-176 in the attic and wired it all up... Anyway, turns out the tones were from Berkshire County in MA. It was perfectly clear too. Obviously its not a big deal to Hartford if they're simulcast channel gets stepped on, but I would imagine that if I can pick up Berkshire from South Windsor, then Berkshire can probably pick up Hartford SIM on their dispatch channel. Wouldn't that interference be a problem? Even if the towns all had tones in their pagers, once they dispatch the channel is open. Maybe I am missing something.
