Hi Steve -- Check the address. Perhaps the '756 and the '765 use different addresses. I know the '756 and the '756PRO have different addresses. If they are different, having the right baud rate won't help at all. I manually set the baud rate to 19.2K on both WL and my '756PRO and it works great! 73, Bob Green W6BBL w6bbl@arrl.net
