Companies have been reporting to various houses for "radio training" and concentrating on the "Mayday button" and a general refresher. A friend of mine who attended it described it as "nothing really new except don't press the big button on top unless you need it!". As I previously mentioned, by doing so, it transmits a "dead key" over fireground until it can be reset and if you happen to be in range, your scanner will lock up on Fireground.
Another item of interest was the 460Mhz changeover timeline. While nothing is set in stone, January 2024 it is expected to be fully grid tested, and a "soft" migration. That usually is code for EMS first, and if it works well, then Fire. The conventional channels are in the code plugs as they are now. Admin, Fireground, Ops channels, Fire Tac are retaining their channel position. As it's been noted, Fire-Citywide's frequency is changing, just not the channel position. EMS Zone will have the Fire channels on the upper channels, while the Fire Zone will have Main and Englewood Fire on the first 2 and last 2 channel positions as before.
In the other thread:
Chicago Fire Department 460Mhz. P25 a contributor posted the flow sheet for radio programming. While I wished the input information would have been redacted at least, it appears that it was accurate and I'll leave it up to others to decide if they want to add it to the database.
