repeater.

Bob,
Look here for the modified audio board.

The squelch control circuit is there, uses the Micor, MSF, high
speed squelch.

Thanks to the people who posted the link. I had seen
that page earlier but didn't follow the signal off the

The pot in the control head seems to have its arm and
one end connected to ground. The other end goes
through some resistors before leaving the control
head. I can see the effect of
What exactly is a community repeater? I've seen references to it, but
I haven't seen a definition yet.

Bob,
The info you need is contained in FMR-1735A-1 dated June 1996
The Audio squelch board in the radio is replaced with HLN5342ESP01
From Pin 9 on the front connector (the former busy light line) on the
interconnect board, the signal feeds through JU1510 to pin 12 of J21 the

A community repeater is shared by multiple users, each using a different
PL/DPL code. If all users have decoding set up and the mic hung up, no one
hears anyone else until the user goes off hook. The hardest part of
operating a community repeater system is to educate all users that if
Anyone have a recommendation about a mobile radio to use as a building
block for repeater systems? I'd be looking at UHF, wanting to cover
430-450, and want something that can serve as a good tight receiver,
exciter, or low power link transmitter. The idea is that if there is

Problem temporarily solved. While tracing the signals
around U1103, I found no Detected Audio coming into
pin 8 of J21, however when I pushed on the pin just a
bit, the radio would then squelch up and the pot
worked like it should, along with the one on the audio
board which was also dead. I
Too bad you're ruling out a crystal rig... I have several Johnson PPL6060
rigs, which are very easy to duplex and make great low-power repeaters/exciters
or full-duplex link radios. Definitely would meet the inexpensive part...

Terry,
Look in the files section for a file named tonechrt.txt
It should give you what you need.

Worst problem was an electrical contractor and a materials hauler. The
haul guy had instructions to report to base when he reached the gravel
pits. This is unit 10, I am at the gravel pit, where do you want me to

Thanks for the info. At least my tracing down to pin 9
was correct. I don't believe anyone has mixed boards,
but now I can trace it through.
The BUSY LED on the front panel seems to be on
whenever the radio has an open squelch. I don't
remember if it also opened with a coded signal.

I have two Kenwood Community Repeaters, one on UHF and the other on VHF. The
thing that makes them a community repeater is they have a multi user CTCSS
or Digital Tone Panel and each user/customer is assigned a tone. The newer
mobile units and portables are set up for BUSY CHANNEL LOCK OUT which
Ahh... that magic Busy Channel Lock-out feature that never
seemed to be available, enabled or programmed on.
In days of old (when knights were bold) you'd have one or
two guys on the frequency with high powered base stations
and no desire to share the frequency. After a few butt-head
events
George, the PPL6060 is a good radio (plug for anyone else looking).
I've got quite a few UHF Mitreks sitting around that are my fall-back

technology. But what seems to keep happening is that the old stuff
just can't be beat

Mike,
A community repeater is simply a shared repeater, and the individual
subscribers have unique PL or DCS tone pairs assigned to them. For example,
Ace Taxi might have PL tone 82.5, Jones Ready-Mix might have 97.4, and Smith
Funeral Home might have 131.8. When the radio traffic is very
