Could it be the PIDD gauge that is setting off the interference? I just bought a 17 snocheck with this gauge. I also have the bca radio. Im going up tues the 29. Ill test my radio also.
On my '16 with the basic gauge I had bad interference. As soon as the sled went above idle, the radio squawked. Constantly. I ended up shutting it off unless I needed to talk to someone. Just my BCA though, my Rino never has had an issue.
