Icom A210e problem

Awe Man, if all electrical gremlins were that easy John. Maybe I would be done with this project.

Had a similar problem with my iCOM A210. Applied several (lower cost) fixes before considering another radio. John McBean was a great source of information which helped in exploring solutions. We have an Advanced Flight Systems EFIS and installed filters on all the DB connectors (purchased from AFS). Replaced all my radio coax with new RG-400. Although the KF frame is an adequate ground plane, John mentioned I can get a bit more range with a 1/4-wave ground plane...so I installed that on my main antenna just behind the turtle deck (inside of course). One of our EAA Chapter members also mentioned that if you have a USB power outlet converter, it can be noisy. I put it on a circuit breaker and added a filter capacitor to the input leads behind the panel. Bottom line, the noise and squelch problem are gone! Not sure which of these fixes solved the problem, but I now have great noise and squelch control.

The radio was good again this weekend once out of the hanger but replacing the coax is one idea we will consider ,one plug was replaced initially. I have tried with the usb disconnected but with no difference,also the voltage regulator was unplugged(without running)
I just can't understand what has changed.My main concern is this problem may be the start of a later reliability issue.
My panel and aircraft are very basic so there shouldn't be to many sources of interference.
Thanks

For what's it worth......If you have any LED lights operating either in the hangar or unshielded wired LED lights in your plane, you may very well experience either static or squelch interference in you radio. The location of your aircraft in relation to these lights may be part of your gremlin problem.
