It's incredibly snug, and thanks! I didn't even have room for a bracket, so they are mounted with industrial Velcro. I wouldn't really even need that, as it is such a tight fit.
As for the MDC thing, it's an Allegheny County biblical law about having MDC identifiers. Not that I disagree with it at all, because it's a good idea. Even if I did disagree with it, what would it matter, in that it's their rules, and overall the people at County are awesome. I just can't see dropping the dime for Motorola MDC-capable radios that won't even fit in the mounting location, when I use these to talk to County once, maybe twice per year. Mostly they are for listening, as I have some trouble hearing nowadays, and I can't hear my pager in the car. As for talking, I don't do that much of it, and when I do, it's usually on a portable.
It's kind of confusing, really. PGHSurge - I know I have heard Kenwood-protocol signalling on the police channels (particularly North Police 11), along with some DTMF ID's on West and North EMS, and one agency (Plum, I believe) on East EMS uses post-transmit Fleetsync. How are these being integrated, or do they have time to get new stuff?
