Noel From: owner-jabiruengine-list-server@matronics.com [mailto:owner-jabiruengine-list-server@matronics.com] On Behalf Of Michael Hilderbrand Sent: Monday, October 19, 2009 11:20 AM Subject: JabiruEngine-List: Radio popping Hey guys, I am doing some initial ground rounds with my Jab3300 engine and was noticing a popping noise in the headsets - while receiving ONLY. The popping noise is pretty bad. At first I thought is might have been the other aircraft's radio (flying in the pattern), but after tuning to a local ATIS I got the same popping sound. I am just trying to see if it might be something obvious, something that one of you might have experienced as well? It does not happen when the engine is not running. I am thinking that maybe I should start out by buying resistor plugs? I am NOT an electrical person at all... but I did try to wire per the Aeroelectric manual. Any thoughts?

It has a tendency to jam at low throttle settings such as late final and it jams harder when you try to open the throttle quickly as in a go around.

My attention was really focused on RPM, EGT, and CHTs at the time (trying to fine-tune an Aerocarb for first flight operation). At the time I was aggressively changing RPM but was on the local frequency - traffic transmissions were too short in nature to notice a change in popping. When no one is transmitting everything is normal. I will listen to ATIS continuously on Friday while running the engine and report back. Thanks!
