Hey, have a '78 model Alert Monitor, M03CNB1102B
VHF unit, silver front with black case, reset/alert/mon functions.

Questions:
Original battery type, location, voltage?
Frequency range? Will it do 146.000MHz?
Is it possible to turn down the volume on the alert tone?

Need schematic, tuning and recrystal instruction.

Any help appreciated,
thanks,
rb
