Base
As described previously it is envisaged that base has overall control over selecting which repeater is required, changing them as required by hill party move-
ments.
Switching a repeater on is achieved by pressing one button on the base radio, once for repeater 1, twice for repeater 2, three times for repeater 3 and four
times to turn them all off, then change the base radio channel to Rebroadcast. When a repeater comes on it sends a number of beeps back to the base on
the TWC, 1 beep for repeater 1, 2 beeps for repeater 2 etc, so that you know that it has come on.
Note: If any repeater is turned on all other repeaters automatically turn themselves off to prevent repeater lockup. i.e. If repeater 1 is on, and repeater 2 is
turned on by pressing the repeater “control button” on the base radio twice, then repeater 1 will automatically go off. When a repeater is switched off, it
sets both radios back to the channels that they were on and the display returns to normal.
The “control button” button I am using on the handsets is one of the buttons on the side of the radio and on the base station it is the “=” button (labelled
on the screen as CntRpt). It can be any button, including the numerical ones.
I have also set the repeater to broadcast its identification (1 beep for repeater 1, 2 beeps for repeater 2 etc) every 5 minutes to remind and reassure the
base operator that the repeater is still on, in range and functioning correctly. This transmission is on the rebroadcast channel so hill members don’t hear it,
and is inhibited if there is radio traffic at that time.
Both radios and/or the repeater can be used on the move.
Using the diplexer gives the repeater a range as good as a standard base set (as there is no desensitisation from the transmitting radio), so in theory the
distance from the base to hill party can be twice the normal radio range and go around a corner.
This configuration does not suffer from the power on problems
