This was despite the Mag having been overhauled about 170 hours prior to that.

Tim ------------------------------------------------------------------------- ----- From: Jeff Luckey To: "aeroelectric-list@matronics.com" Sent: Sunday, April 6, 2014 10:04 AM Subject: AeroElectric-List: Magneto Noise I flew w/ a friend recently and when trying to get awos for our destination airport (which is a pretty weak signal) it was almost impossible to hear due to magneto noise. The radio is a Garmin 430W in a Cherokee and we were around 10 miles from the airport. When we got within 3 or 4 miles the signal was much clearer. All other transmissions with ATC & towers were acceptable but I noticed at high volume I could clearly hear magneto noise in the background. I'm wondering if that's just the way it is or if there is a problem with the magnetos or P lead wiring. There must be one of Bob's handy-dandy write-ups on this topic but a quick search of AeroElectric.com was in vain. Can someone point me in the right direction?
