So do you ride a Polaris by any chance? I do and also ride with the BCA rep. that rides Polaris. Myself with 2 different Baofeng radios and both were experiencing the noise interference when I was riding. So I ask my buddy and he tells me they have had some complaints about interference with the BCA radios but mostly from guys who ride Polaris. So I check my spark plug caps and both seem good. A few more rides and being further annoyed, decide to change my plugs. What do you know, the interference is suddenly gone. Prior to this I also increased the squelch levels but it did not help.
Yeah. Agree it could be interference from the sled. One of my buddies was saying his would have static bursts as he was on and off the throttle. But I have had it many times while having a break and all sleds shut off!
