sounds like you need to try to rewire the whole system, separate
the TX and the RX and wire them into the CAT 300 separately.
i have never been fond of systems that use an internal controller.
i would rather have 2 separate radios, one for TX and one for RX
and tie them into the controller.
just my 2 cents worth.

Subject: [Repeater-Builder] TKR-820 Timeout Timer Problem - Frustrating!
Before you all banish me to the outer reaches of Mongolia - or somewhere
else - because of all the questions I keep posing about this machine, please
understand that I have tried to research this issue in the technical
material I have available to me and I keep coming up empty. This is why I
keep prodding. I know there is quite a wealth of knowledge here, so Im
trying to tap into some of that knowledge
That being said, heres the latest on this frustrating issue. I have a
TKR-820 interfaced with a CAT-300 repeater controller. The CAT-300 operates
fine, whether the internal controller is turned ON or OFF. The only issue I
have is with the internal timeout timer. Previously, the repeater would shut
itself down after 2-1/2 minutes when the internal controller circuitry was
turned OFF. (REPEAT button OFF) The external controller was set for a much
longer time, so I knew it wasnt the CAT-300 causing the problem.
I went to the site a few days ago, and adjusted the TOT pot on the internal
controller to its maximum (5 min). I then made certain that the external
controllers TOT was set shorter (4 min) than the internal one worked just
fine. (So I thought
) I departed.
Apparently, I departed prematurely. (No jokes here, OK? Hehehehe)
Anyway, this evening I heard two stations using the repeater and at 5
minutes the repeater dropped. DAMN!! I went back out to the repeater site to
trouble check some more. I found that if I unplug the external controller
and have the internal REPEAT function turned ON, the internal controller
controls the machine I expected this. (Not what I want!) If I unplug the
external controller and have the REPEAT function turned OFF, the repeater
does not repeat plug the controller back in, and the repeater works. (This
IS what I want!) However, if I dont turn the REPEAT function ON, the
repeater times itself out way too soon I presume that this is because of
the INTERNAL timeout timer
So, how do I totally disable the internal timeout timer? It is becoming more
apparent that the timeout timer functions in two ways the first, as a
repeater timeout timer (of course); but secondly, as a stuck mic timeout
timer when the radio is in base station configuration (simplex operation)
This has really frustrated me, and now Im on a quest to figure out just how
to shut that damned internal timeout timer off once and for all. Any
suggestions?? Can I just unplug the internal controller board altogether?
