Geographic location, profession, and general interests having the strongest bearing on what we like to entertain ourselves with, I'm kind of an oddball when it comes to monitoring radio traffic......:w00t:
I'm a professional fire fighter / EMT...on the job for 23+ years now. I've listened to, and participated in a lot of radio traffic during that time, and when I'm off duty it's about the last thing I want to hear. We have Motorola pagers that activate if we have anything that goes to a second alarm, when that sounds I listen, otherwise I could care less what happens. The only exception to this rule is during hurricanes or Nor'Easters, and that's only because I'm responsible for the 3 army surplus M-35 storm trucks our dept operates.
Early in my career our Police dept used the 400mhz band, and we would monitor their traffic in our stations, This was mostly because the dispatchers would alert them to fires, motor vehicle accidents, and water rescues before they would notify us, and we would get a head start on the call if it was in our response district. They have since gone to an 800Mhz digital trunk system, and we can no longer monitor them.
I used to drive the other guys nuts because I'd take out all the frequencies to other area FD's and replace them with HAM repeaters, and VHF Marine channels. I found listening to some HAM chatter, and who's catching what fish a lot more interesting than listening to a bunch of ear pearcing alert tones being transmitted over the various FD and EMS bands on VHF.
The down side to my scanner apathy has bitten me where the sun don't shine a couple of times recently, and I missed a couple of recalls because I never carry my pager. Missing a recall means they got something big, and need everyone off duty to come in and man the station, it also pays time and a half.....
This is one of the reasons I decided to get a new Yaesu VX-170, I'll be able to yack on the local HAM repeaters, monitor the VHF Marine bands, and listen to my Fire Dept while I'm out on a remote back bay sod bank fishing...
