[Elecraft] Difficulty with PSK

[tom wylie]

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.

Thanks to all who have responded....
