A simple rebroadcast device capable of operating on your own Team Working Channel and a few others near to you would be built like this.

This is the ‘Simple Repeater’ as described in the TMC Radio publication A9k-501. The only difference is the addition of the diplexer allowing use of frequen-

cies, in both radios, that are close to each other.

De-sensing is reduced to a very low level and only a single aerial is required. How-

ever, changing channels is no easier with this device than with any others so far

described. A control head is still required. For single channel working, ie on a team

TWC only, this configuration is all you will need.

TWC

147.350 MHz

The radio frequency signals

are ‘steered’ to the correct

radio by the tuning coils.

Diplexer

Crossover cable

The ‘Simple’ In-vehicle, Re-broadcast Device.

A practical, if basic, solution. In a vehicle, a separate radio would be used for normal voice comms. The above

device is only switched on when rebroadcast is needed as shown in the next section.
