birmingham al

I have a BCD536HP and 436HP and neither one will receive anything on the Sheriff's system other than Centerpoint channel. Does anyone know what is going on? I can pick up Bham FD dispatch and Bham PD South. Weird but need to be able to receive all the channels.

I would like to monitor Birmingham Fire & Rescue but I do not have their frequencies. I know they transmit on a 800mhz freq but I have heard they also dispatch on an analog channel as well. Does anyone have the frequencies or tell me how I could monitor the BFD? Thanks for any help!
