Some of the Pactor MBO's are Pactor 2 and 3, The PK-232 only supports Pactor 1.
For the waterfall in DD, you need to have the soundcard interface in the PK-232 and be in a soundcard mode. Since the PK-232 moves the soundcard connection between the soundcard and inside the TNC, that's why you dont see a waterfall on Pactor. Give me a call or an email and Ill help ya set that up.
Most of the time, Pactor is on LSB (on the ham bands), but only the MBO's use Pactor for the most part now. Very little keyboard to keyboard Pactor going on.
