This is now sorted. I am using DATA A and have had successful QSOs. I believe the manual is a little ambiguous in the description of the modes and assumes knowledge or familiarity with the products, which is a problem for somebody who just wants to try things out.
The MircokeyerII is a USB interface designed to go between the rig and the computer carrying all the audio and switching. It also has a built in Winkey for CW so is indispensible. See http://www.microham.com/ for details if you are interested.
