Concord Fire Main Channel has changed the Private Line (PL) Code.
The new code is: 146.2 Hz Analog (the old code was 054 Digital)
Receive Frequency is still 483.5375 MHz PL 146.2 Hz
Fire Ground Frequency is 483.7125 MHz PL: 146.2 Hz
The PL code was changed because of difficulty with Narrowbanding older radios.
