86M20J Posted April 12, 2021 Author Report Posted April 12, 2021 ZERO corrosion under the antenna or anywhere else on my plane. Getting a new coax and antenna right now. Coax is being provided by the shop as they didn’t install a new coax when they put the 650 in. Either way, they are test flying it Friday and problem should be gone. Thanks for all the info.

bradp Posted April 13, 2021 Report Posted April 13, 2021 Fwiw my radio issues in the past have been solved by a multimeter ring out between the coax shield and the conductor - and/or- A little digital SWR meter

My 430W was acting similar about 6 months into having it installed and a quarter turn with an allen wrench eliminated the issue. Is this allen screw the mounting screws to the rack?
