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. 73 STEVE - KC8RSR [EMAIL PROTECTED] http://kc8rsr.tripod.com/ AIM / YAHOO = KC8RSR -------Original Message------- From: N9WYS Date: 11/09/05 22:24:11 To: Repeater-Builder@yahoogroups.com; [EMAIL PROTECTED] Cc: [EMAIL PROTECTED]; [EMAIL PROTECTED]; [EMAIL PROTECTED] 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? Mark N9WYS YAHOO! GROUPS LINKS Visit your group "Repeater-Builder" on the web.
