I had a 3618 slaved to my 922. It had a skew adjustment somewhere in the menu, but I never had to use it since the 922 takes care of that. I now have a 3688, it has the same hook ups in the back as the 3618 and the opiton of turning the skew on or off in the antenna configuration. As a shot in the dark, I would say yes it will operate the polarities on a BUD.
