Chuck, John Bob, Derek, Eric, Mike, JohnB, and Tom, Thank you all for the helpful suggestions.
The connectors appear to be perfect, and they check out with DC. The cable on the RX side is double shielded RG142B/U. The cable on the TX side is not marked with a complete designation. It says AWM Style 1354, but there are many cables that are said to be UL AWM Style 1354. Some of these are 75 ohm, some are 50 ohm. This cable is only six inches long. I plan to replace this as soon as I can get RG400 or other suitable cable. BNC connectors are used on both the RX unit and the TX unit. I don't know what it means to have a feed through capacitor in series with a control or audio or power cable. However, a capacitor to ground might be good to get rid of stray RF. Pray if you are so inclined. Otherwise, hope we can make the physics work. Thanks again, JohnT -----Original Message----- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Chuck Kelsey Sent: Sunday, August 31, 2008 3:06 PM To: Repeater-Builder@yahoogroups.com Subject: Re: [Repeater-Builder] Wits End -- Desense I was wondering the same thing. Has someone added some wiring and subsequently breached the integrity of the shielding effectiveness somewhere? First thing to come to mind is controller interfacing and CTCSS wiring.

Also you might put a few small ferrite beads on each wire as well. John VE3AMZ
