Dave Binks at Duddon & Furness has designed and adopted a system where both radios can be independently used on all channels and a significant level of
control via selcall is available. Individual rebro vehicles may be remotely activated and the user is advised as to which rebro he or she has just switched on.
Operation of the system is best left to his own words and the following section has been supplied by Dave.
His diplexer requires modification beyond that already undertaken, on our behalf, by Roger Taylor and a picture of the finished article with the lid removed,
is shown below.
Dave’s modifications involve the fitting and control of an additional relay but the functioning of the device is still based upon the TMC DMAP repeater that
has been enhanced by both software and hardware mods. This is the most sophisticated system we currently have available to us and the needs of each
team as assessed by the radio officer will fall somewhere between the very simple and the version shown here. It all depends on what you think your team
can handle successfully as someone’s life might really depend on the proper functioning of these devices! Build what you think your team can cope with.
