Hammie radios?
? Where the heck did you take your test??? 
In the original post there was no mention of trunked radios so I asked the question to find out what he was using - and he gratiously gave an answer. I guess I'm not as smart as you "hammies".
Which test??? I hold several communications certificates. Some were taken at the shop others were taken at manufactures sites, or at local hotels at testing sessions.
I was being smart... you still didn't seem to figure that out.
Reality is about the time you go clipping the transmit limiter out of your ham radio so you can talk to the police, the FCC will be talking to you.
Ham's do not, should not and can not legally provide ANY inneroperability assistance for public safety. You at best can pass health and welfare traffic. And twith the new HIPPA rules, you almost can't do that. This isn't the fifties. Public safety communications is far better than in the past. And it's technology has advanced. Ham radio? Not so much. If you enjoy ham radio as a hobby, great. Get away from the idea that it's going to may you a hero some day because chances are, if you have repeater coverage so you can call for help, by the time you get your old technology ham radio out and get the autopatch up, someone has called 911 and help is on the way.
