| Additional info: |
There are three versions of this radio known to me. The difference is mainly
the "Channel" selector and its behavior besides the "Synthe" position:
Version 1 has five fixed channels and no repeater duplex position.
Version 2 has four fixed channels and one repeater duplex position.
Version 3 has three fixed channels and two repeater duplex positions.
