Composite aircraft with foil antennas embedded in the wings per RST Engineering manual. I have discovered that I couldn't hear anything on Com2. All aspects of Com1 work fine. When I key the mic three times on Com2 (for airport information), I don't hear anything (no surprise). But if I switch to Com 1, I hear the announcement. Which indicates to me that the mic keying is being transmitted. (I haven't been able to do a voice check yet). As a test, I swapped the antennas to the radios. The problem moves with the antenna. So I figure it's either a bad connector termination, bad cable, or bad antenna. I'm planning on checking for continuity between the center conductor and shield from the radio to and the last connector which should tell me if it's the cable. Does anyone know of way to you have any suggestions as to how to determine if the antenna is causing the problem?

The most likely problem is a bad connection between the coax and one of its connectors or between connector and antenna. The antenna foil could be cracked. -------- Joe Gores Read this topic online here: http://forums.matronics.com/viewtopic.php?p=447251#447251 ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message aeroelectric-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/AeroElectric-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/aeroelectric-list Browse Digests http://www.matronics.com/digest/aeroelectric-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
