Ian, our ham club has talked about putting one of
their repeaters on a different frequency and linking
them together. We operate both on the same frequency
now, one at a time with separate tones.
My proposal to them was to put a receiver at each site
for the other repeater and in-band link them. I think
that is what you are proposing to do also, except you
would use a separate transmitter to do the in-band
link. Using a separate transmitter in your case may
be more easily accomplished since you can use the same
receiver CTCSS tone and transmit audio to both your
repeater transmitter and link transmitter. Using a
separate receiver as I proposed to our club would be
easy for our single CTCSS system with each receiver
feeding the controller input through a circuit which
gives priority to the local repeater receiver.
In your case, you could put your link transmitter on a
separate beam pointed at the other site and let the
normal tone controller take care of the other
repeater. The only thing I would suggest is that you
configure your controllers to only transmit the CTCSS
while a user is key down, and not during any ID or
squelch tail. With a decent link, you would have full
interoperability with both systems, and no key up
delays due to the other station being on the other
repeater.
I have not run across a two repeater system linked in
this manner, but it does seem to be the easiest way to
get the same audio on both repeaters. In your case,
that may be a slight detrement since users on the
second repeater would be prevented from using the
repeater when the first repeater was busy. Using the
receiver link I proposed would allow a station to use
the second repeater by overriding the audio from the
first repeater by simply keying the second repeater
input.
