Default PHX Fire

Any idea when they (and other suburban fire services) will go digital full time (I.e. hazard calls as well)?

I would be shocked if building interior fire communications ever went digital, unless some breakthrough in digital dependability occurs. I think if digital could be improved, it would have happened a while back. Analogue is not only dependable, but has a relative short range, thus keeping building interior communications "in the family", so to speak.

Caveat: I make the above statement having no personal knowledge of radio electronics, but am relying on "conventional wisdom" (which I usually laugh at) and 55 years of listening to 154.190, lol.

Not any time soon. Phoenix Fire did testing a few years back and analog was proven to provide better audio clarity in most situations especially in "hazard" situations that require use of an SCBA. 700/800mhz analog was proven to work the best, but as Phoenix already had an extensive VHF receiver infrastructure in place, they chose to enhance the VHF system rather than start from scratch with a 700/800mhz analog system for fire.

The full report can be found here:
https://blog.tcomeng.com/wp-content/...adioreport.pdf

Even though this was done in 2004, there has not been a major change in digital communications as it is still P25 for most Public Safety. Now with P25 Phase 2, audio quality is slightly worse at the gain of better spectrum efficiency. Until there is a major advancement in digital, it seems analog is here to stay at least in Phoenix. Mesa is now even moving back to a VHF analog system for fire after being digital for many years.

In Phoenix, that transition is currently scheduled for January 1, 20-never.

LOL on their website it says (and I quote) "Once we implement the system for non-hazard calls, we will begin the process of transitioning to the troubled system for all operations."

Also I believe all FDs have the new APX radios. The Phoenix site hasn't been updated in years.

Here is what Phoenix Fire thought about the transition to the RWC (when it was 800mhz in the past).

LOL this was that parody. I was hoping you had the link to their video they had up for a while while the transition was going on.

From what I understand FFD has no interest in using the RWC system for fire ground work.
