Re: [Repeater-Builder] Micor Ribbon Cable
It's a common problem, Moto. fixed it by coming out with the unified chassis which eliminated the ribbon cable. You might try making up jumper wires to eliminate the ribbon, you can get edge connectors if you wish, or tear the ribbon apart for the plugs and start over. It's a pain, but it works... otherwise pickup a unified chassis on ebay ( about 70.00) and transplant the boards.

I go to the site. power off the Micor, reseat the 50 conductor ribbon cable on the back end of all three chasis, and all seems to be better for a while. But it returns. Has anyone experienced this before, and how did they resolve it? Thanks Steve
Re: [Repeater-Builder] Micor Ribbon Cable
I have been told that this is a known problem. The fix is to use a unified chassis. I may be able to hel;p you with a unified chassis. 73 Glenn WB4UIV At 01:58 PM 02/14/07, you wrote: We have a VHF Micor and during cold weather like we have now, we loose the audio level and it seems that our RF ouput is down.

RE: [Repeater-Builder] Micor Ribbon Cable
Steve, Motorola recognized this problem a long time ago, and has a fix: Stabilant 22A. The suggested action was to first thoroughly clean the contacts using a Gold Guard Pen or equivalent, and then using a sterile cotton swab moistened with Stabilant 22A to wet the contacts just before mating the connector. Almost like magic, the problem disappeared. This stuff is not just a solvent/cleaner like De-Ox-it or similar wannabes, but is a unique polymer solution. You can buy Stabilant 22A directly from a number of suppliers, or you can order it from Motorola Parts as #1180384V93, for about $45. I bought a 15 mL vial of Stabilant 22A five years ago, and have used less than half of it. Yes, it is very expensive, but a little goes a long way. When properly applied, it works as advertised. My disclaimer of any financial interest in the product applies; I use it and am a satisfied customer. 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of n1tec Sent: Wednesday, February 14, 2007 10:58 AM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] Micor Ribbon Cable We have a VHF Micor, and during cold weather like we have now, we lose the audio level and it seems that our RF ouput is down.
