The completed demonstration repeater/rebroadcast unit. This is a multiple use version of the device and is unlikely to actually be
built like this for real use. However, for demonstration purposes:-
Fitted with a telephone handset (9025) controller the TWC radio can be used as a normal voice channel set in a vehicle. A direct
contact from the radio to the antenna is needed in this instance and this would be provided by an antenna change-over relay.
In some cases, it may be advantageous to fit a
controller to a fixed, remote site as it allows local
control of the radio should this ever be necessary. A
telephone handset is used as this is the easiest way to
provide receive audio in the absence of a loudspeaker.
This is only possible because the cross-over functions
have been provided by the facility/power connector
and not the Simoco cable that normally fits in the RJ45
sockets. These remain available for use with
controllers etc. Here they have been extended to the
outside of the case to make things easier
