From: mark vultaggio <mvultaggio@hotmail.com> Has anyone had a problem with an xm weather receiver causing an over-ride o f the squelch function of their com radios. When I have the xm box on and connected to an AVMap portable moving map/gps=2C much of the time there is a lot of noise (static) that sounds like the squelch button is pulled on my collins nav radio. The static continues throughout transmissions from atc . Occassionally everthing is quiet and works properly=2C but there are als o lots of times when there is static=2C even when radio transmissions are q uiet. As soon as I pull the breaker that controls power to the xm box=2C t he noise stops immediately. I have the box mounted in the rear of the airc raft on the hat shelf=2C the power and antenna run to the front of the plan e under the headliner=2C and the antenna for the xm box is sitting on a gla reshield mount=2C right next to the gps antenna for the avmap. This is in a beech sierra aircraft. I am going to go fly and have someone disconnect the antenna lead from the unit in flight to see if it is the antenna. I w ill also disconnect power at the unit to see if that has any effect. I wil l also pull the data transmission line out to see what that does. thanks
