All FM transmitters legal?
AM and FM wont buddy box together. You will have to find on old FM TX to use as a buddy box with your
FM TX. The AM will be a little more pron to interference. That is why I would use the FM. I have also heard some people say the TX are narrow but the RX are wide band(pre-91). The market to sell the old RX and module is almost nill. $20 should buy an old FG series TX to use as your buddy box. later daveo
