Thanks, Al. I appreciate the suggestions. The battery and voltage regulators are new. If this problem is a variation of my previous radio problems that I thought was associated with the charging system, it manifests itself in a way that causes interference with my handheld radio as well. In Kingman AZ, I switched to my handheld radio and still had bad communications. That leads me to believe that the engine is generating a bad RF signal.
I didn't check my handheld radio this time, but I am going to put it on my list. Thanks.

First start with your grounds, ALL of them. Engine to airframe, control surfaces to airframe, battery to airframe and avionics (including the phone plugs) to airframe. Then why not go ahead and replace the little bit of coax you need with the good stuff, RG400. Remember that the 400 will use a different part number for the connector. Believe me, not those who say they're the same. Next, the item I would look at would be the condition of your battery. Try to get it to a shop that can properly test an aviation battery. I'll assume that your mag condensers are new and that the voltage regulator was also checked when the alternator was serviced. > > That about covers it all from what I can tell.
