Base transmits on the TWC but
monitors 147.350MHz on Receive
only either by scanning or by using
a second receiver
The hill-party transmit and receive on the
TWC but have 147.350MHz Rx only in a
scan group.

The Schematic for Moffatt MRT’s suggested system.
Any signals received by the rebro vehicle on the TWC are re-transmitted back to the base. Both the hill-party AND the base operate on the TWC. Although
the 147.350MHz frequency can be monitored by the hill-party, it isn’t necessary for them to use it. Control of the audio output levels on both base radios
would need to be good to avoid howl-round and a head-set would probably be better suited than loud-speakers. Each ear-piece of the head-set would pro-
vide audio from only one of the receivers. PTT is only required by the TWC radio.
