There is a "interference" or "sensitivity" type option that can be set from 0 to 10... mine is at 5. But this option is to cancel out incomming noise. not outgoing. I find that my KYD radio sometime broadcast to strongly for cheaper radios and they pick me up only when they are further away.
I need to dig out the manual. If you have it try looking for that setting setting.
Its like function + 0 or star... i don't recall off the top of my head.
