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: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of n1tec Sent: Wednesday, February 14, 2007 10:58 AM To: [email protected] 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. I go to the site. power off the Micor, reseat the 50 conductor ribbon cable on the back end of all three chassis, 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
