      1. The 8 pos rotary switch is a good idea, access from the outside
      through a hole with a screen print giving indication of the 8
      positions could be handy.This means there would not be any need to
      open the case to change frequencies.
      2. Are the frequencies going to be fully defined by the user (user
      can define any freq within the hardware limits of the Transceiver?)
      Or is it going to be limited to what frequencies are hard coded?
      If they are hard coded, what will be the frequencies?
