yeah because in berlin, police and fire are the same dispatch so this frequency isn't used for voice at all because fire and road/highway dept is on vhf and police are on 800 mhz , i figured out that this frequency is used for the fire depts siren's because everytime a call goes out the pager tones go off on 154.3400 which is berlin's fire dispatch and fire ground and then tones go off on 45.1200 for sirens i think.
