Intercom

[Goldwing09]

I have a Pair of J & M helmet headsets that work fine on FM radio, just got a CB and have a squeal when I key the mike. I've had the swr set They replaced the CB, the antenna & the headsets, still have squeal. I can hear on the CB just fine. Also when I put it on intercom the FM radio volume goes up & down. Any thoughts. Thanks

The squeal could be from a bad coax cable(often overlooked),not sure about the oscillating volume. Best of luck

First I would try someones elses helmet or have them plug into ur systema and see if it does the same thing..or try urs on thier bike.
Then I would go over the wires and coaxe real good...sounds like U have a ground some where... or maybe a pin that is not seated in good, maybe even the key U push down to talk ??? does it do it only when U are setting on the trike or does it do it all the time even if U are standing beside the trike????

Last I would call J&M, they have been a pretty good company and have helped me with my problems and questions b4..
Good luck and let us know what U find...
