I've been to Chicago and monitored their fire-ground ops, it's no different than FDNY, and it doesn't "kind work" in NYC, that's how it is. FDNY has been VHF since they invented it, and it worked, but with the FCC realigning the frequencies that were used for fire ground ops from a 2 watt channel to a 110 watt channel they had to move. FDNY is still dispatched on VHF (for now), the man radios are UHF carrier squelch(which I don't agree with but understand their thinking on it), which have a better building penetration than the VHF. (excluding GCT which has a old in tunnel repeater system that is being updated to UHF at this time) This still doesn't relieve the Chiefs from the responsibility of having had radios in storage while the front line troops didn't have enough. FDNY took a bad situation (after a few close calls) and made good with it by taking all their digitally programmed radios and going analog, CFD could have done the same while working out the kinks of their new system. This whole nonsense of going digital is from the salespeople, who eventually want all P.S. to go encrypted, and it's a lot easier to do digitally.
The main thing here in relation to the LOD deaths is it's not the band that they operate on, or even the mode analog vs digital, it's that someone high up didn't step up and say, STOP lets go back and rethink this before someone gets hurt.
I worked NYC EMS for 10 years, and the fact that we were on UHF and FD was on VHF had very little to do with our patient care. We always when we had to was have a face to face with the command officer on scene before we started, you don't need a radio for that.
The department that I am in now, can have as many as 4 radios at command at a big scene, it's all about command and control. You have to know what you people are doing at all times, and if it takes 2,4 or 10 radios that's what it takes. If the officer is on one channel and some one is calling a MAYDAY on another it doesn't matter if it's on a different band or a different radio. He or she should be listening.
