Have a skipper 300, that if amp is not on and preamp switch on, no receive gets through it. Works fine when amp is on and preamp in the on position, but I really don't need a preamp and have to bypass the amp when running barefoot else no receive getting to the base radio. This is the model with the little circuit board on the rear with 2 white square components and one regular type relay to the left of that board, if you looking from front to the rear with lid off. I could certainly...
