Hi!All, I am requiring a discontinued Jefferson chart. If anyone has it I would be obliged to hear from them. I have a VFR/GPS Europe SOUTH Chart of Aerodromes ( overview chart) and have a non fly project to combine it with the North Chart. Would anyone having the Europe North Chart who can now spare it kindly contact me either by e-mail or phone :- 01472 852498. Regards to all. Bob Harrison 914 G-PTAG. ________________________________ Message 2 _____________________________________ Time: 06:09:13 AM PST US From: danny shepherd Subject: Europa-List: radio interferance Hi All, Are there any avionics expert who might be able to help ? I have a Funkwerk ATR833 which has worked ( bar having a new face fitted ) extremely well over the last six years. but now works fine until I start the engine, then a lot of interference, virtually unreadable both transmitting and receivering. I did have the panel off to remove the hard wiring for a gps which I dont need anymore. Sounds like a grounding problem to me. I would appreciate any advise. Regard. Danny.

So, did you check all the resistance values of ground pins on the radio and the case all the way back to the engine block or negative battery terminal with a quality ohm meter? All should certainly be less than 0.5 ohms. Generically, there should be no ground loops, all grounds go to a single point in the panel, then to the other side of the firewall. Good luck! -------- Ira N224XS Read this topic online here: http://forums.matronics.com/viewtopic.php?p=447092#447092 ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message europa-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Europa-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/europa-list Browse Digests http://www.matronics.com/digest/europa-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.
