Walt wlannon@shaw.ca From: Gil Lipaz Sent: Sunday, March 11, 2012 7:03 PM Subject: Yak-List: CJ Trim Cable replacement Wondering if anyone has any words of wisdom (or, even better, some photos etc) that would help me install a new trim cable. Mine snapped over the weekend and unspooled off both wheels. Not sure if the tail spool is still intact but the lack of tension leads me to think it is not. I saw some talk about replacing with electric servos but, I prefer to use the cable system.

There several primary noise sources: 1. ignition; 2. generator commutator; 3. generator voltage regulator; 4. rotary inverter commutators. Ignition noise is usually a pop-pop-pop to a machine-gun/ripping noise that increases and decreases with engine RPM. Generator noise usually comes on suddenly when you increase RPM from idle and changes in volume as you turn things on and off. Rotary inverters generally are a fairly raspy tone that is continuous. If you have done an alternator conversion then that replaces items 2 and 3 above. If an alternator is working properly, it will be quiet. If you hear a more-or-less pure tone/whistle that changes with engine RPM, it probably means that one or more of the diodes in the alternator has failed. So, what does it sound like? And if you only hear it when you are transmitting but not when receiving, and it goes away if you unplug the microphone, then it is probably a mic jack grounding problem. The microphone jack(s) should be insulated from the airframe and have their own ground wire that is routed directly back to the comm radio or to the Intercom/audio panel if you have one. The mic jack should have black plastic or fiber washers insulating it from the metal panel. -- Brian Lloyd, WB6RQN/J79BPL 3191 Western Dr. Cameron Park, CA 95682 brian@lloyd.com +1.767.617.1365 (Dominica) +1.916.877.5067 (USA) ________________________________ Message 6 _____________________________________ Time: 05:24:13 PM PST US From: "Joe Howse" Subject: Re: Yak-List: Looking for Joe House marcus joeh@shaw.ca ------------------------------------------------------------------------- ----- Joe....give me a contact number......Marcus Bates ________________________________ Message 7 _____________________________________ Time: 08:33:16 PM PST US Subject: Re: Yak-List: Radio Noise CJ6 From: "Roger Kemp M.D." Magneto Filters and spark plug wire ignition shielding braid.

Look on the Aircraft Spruce website for them. Your work is not done. That assumes that it is radiated ignition noise, not necessarily the case. -- Brian Lloyd, WB6RQN/J79BPL 3191 Western Dr. Cameron Park, CA 95682 brian@lloyd.com +1.767.617.1365 (Dominica) +1.916.877.5067 (USA) ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message yak-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Yak-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/yak-list Browse Digests http://www.matronics.com/digest/yak-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.
