Note - many FDs have FFs switch to a 2nd channel during a MAYDAY - leaving just the downed FF on the original channel - LAFD has their radios set up such that when someone hits their emergency button, the radio automatically switchs to Channel 6 - FDNY has their radios set up to transmit a hot mike for 10 seconds after an emergency button is hit - Boston area FDs seem to have their emergency buttons set up just to send a signal on the selected channel (perhaps the IC radio is set up to receive the alert) - Boston FD has their emergency buttons sound an alert at the dispatchers console - I am not sure what Chicago and Philadelphia do - i know that Chicago FD uses simplex for FG comms (with maybe no base stations on the freqs) -- You received this message because you are subscribed to the Google Groups "massfire" group.
