It`s installed a King Bendix KY97A COMM and a DRE-244E intercom. The problem is that I cant transmit messages. At first I thought there was a wiring failure after seeing the horrible wiring that had been done, so I decided to take out all the wiring and start all over. I took the COMM and Intercom with me home and started making a new wire harness from COMM-Intercom and new wires to PTT`s, Headphone and Mic jacks. After to many hours with wiring and without any form for pin outs and diagrams I thought I had figured it out. But still the same problem accrued. The only piece of diagrams I could find for the KY97A and the DRE-244E intercom was this. http://rv.jpainter.org/docs/dre/pinouts.jpg http://rv.jpainter.org/docs/dre/schematic.jpg http://www.aeroelectric.com/Installation_Data/KY97A.pdf Not very useful but some. I went through all wires and connections but I couldn't find anything wrong. I can hear my self on the headset talking on the intercom, I have music input, the intercom volume and squelch works, I can receive messages from my hand held radio, and when pushing the Pilot PTT I get a LED light up on the intercom showing there is being transmitting a message. The TX synbol on the KY97A also lights up. The hand held radio only receives some buzzing noice and not any voice message. Any one got any ideas ? I am also very thankful for all help and if anyone has got some better diagrams for both COMM and Intercom. Thanks ! :D -------- Kitfox IV w\ Jabiru 2200 Turbo\Aerocarb Read this topic online here: http://forums.matronics.com/viewtopic.php?p=265190#265190 ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message avionics-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Avionics-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/avionics-list Browse Digests http://www.matronics.com/digest/avionics-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.
