Sorry guys... I replied to the wrong email. This should have been in reply to Gregory's email.
Better keep me away from any powered circuits today! 73, Mike WM4B From: [email protected] [mailto:[email protected]] On Behalf Of Mike Besemer (WM4B) Sent: Saturday, February 21, 2009 2:59 PM To: [email protected] Subject: RE: [Repeater-Builder] Micor newbie needs advice Rick, Yeah I failed to mention that theyre mobiles. The original builder stripped all the unneeded parts out of each unit (no TX parts in the RX, and vice versa) so theres no hope in swapping them. I might be able to swap the 440 RX into the 2-meter slot (havent even looked into the 440 cabinet yet) and create a temporary Frankenrepeater) just to see if its the plug or not. The problem is, Im working on a system designed by two hams (one of which is deceased now) and the other just hasnt got time to help me. Ive got limited drawings at this point, and I DONT want to make anything worse. I REALLY need to go out and mark a bunch of cables the labels are starting to fall of and if I disconnect something by accident (which Ive done several times) Ill have a heck of a mess! I ought to have better sense then to get into situations like this!

I will look in my spare part to see if I have my bench set up still kicking around Rick On Sat, Feb 21, 2009 at 12:28 PM, Mike Besemer (WM4B) <[email protected]> wrote: Greetings all, I normally maintain a couple of 'out-of-the-box' (Kendecom) repeaters, but recently I've been asked to help out with another system that is homebrewed from Micors. It consists of 4 Micors (TX on 2 meters, RX on 2 meters, TX on 440 and RX on 440) linked with a CAT-500 and a set of homebrew controls. Lately, the 2 meter RX has become intermittent. For a while, I'd been able to either wiggle the plug on the front of the receiver or give the receiver a good whack and it'd come back to life, but lately it's become more and more obstinate. A couple of weeks ago, I brought the RX back to my shop and pulled all the boards, cleaned the pins and did my best to look for obvious problems. I really didn't see anything wrong, but when I reinstalled the RX, it work fine and I thought (after it ran for a couple of weeks) I must have fixed it. (I have no way of running it on the bench... so it was just a plug-and-pray fix.) Unfortunately, it crapped out again a couple of days ago, and this time reseating the plug and banging had no effect. One thing I did notice that I'd not seen before (it's hard to access the rear of the repeater) is that the plug (on the harness) is missing a piece of plastic surrounding the three pins nearest the hinged side of the handle. I haven't had time to pull up the drawings yet to see what those pins are, but I suspect that may be at the heart of my problem. At any rate, I'd like to be able to run this beast on my bench. Where can I come up with a harness and control, and what (if any) additional hardware would I need to be able to get this thing hooked up? Second, IF the harness plug IS the problem, what's the best course of action? Changing the plug looks like a real bugger. I haven't traced it up to the homebrew controls yet, so I'm not sure how difficult it'd be to swap out the entire harness (if I had one), but either way doesn't look like much fun. 73, Mike WM4B
