there is an RX site on Concourse Pkwy but nearest transmit site is Morgan Falls unless Ron made some changes I don't know about.
450MHz trunking around here? Why? Everyone else is on 700/800, and since Motorola doesn't seem to want to add UHF to the overpriced APEX line anytime soon, it would just create another roadblock to end user interoperability. Like we have it now. 15 different trunking systems, no ISSI roaming, and a refusal of agencies to come to the table and work together.
In all seriousness, UHF would have been a better way to go in metro Atlanta given the terrain and distances involved. But then back in the early to mid 90's pre-Nextel, UHF allocations were about as rare as real estate in Buckhead. And it wasn't what Motorola was pushing. Ironically, all the metro Atlanta agencies that were on UHF back in the day still have some of their licenses (Cobb, Atlanta, DeKalb and Gwinnett). Cobb and DeKalb have some of their BOE's using those frequencies (Cobb school bus maintenance on 460.5 and DK buses are heard on 460.4).
What we really have to ask ourselves is with the advent of most non-dispatch and admin type communications taking place on other services including cellular/PCS, Nextel, Blackberry, etc is there really a need for such large capacity trunked networks? If LA and NYC operate conventional radio systems optimized for dispatch voice coverage in such major metro areas that are 5 times the size of Atlanta metro, why couldn't we have just stayed on conventional and gone narrowband or P25 conventional? Would we have been better served than building out these proprietary closed network trunking systems? Probably so. We may not be closing fire stations and have 911 calls in queue for 20 minutes as we'd have money to pay people to answer those calls and enough personnel to respond to those calls.
