[Elecraft] WSPR with K3

[Phillip Zminda]

I started experimenting with WSPR over the weekend using my MacBook  
Pro 13 in with the Intel processor running Windows XP using Parallels  
virtual machine. I have the audio connected through an iMic external  
USB sound-card and the K3 is connected to the Mac with a generic USB  
to Serial card with the Prolific drivers. I can receive and transmit  
with VOX but the CAT control will not seem to work to change frequency  
or bands. The K3 connects OK to the Mac using K3 Utilities and HRD.

I have tried various setup combinations of COM port, baud rate and  
handshake but can't find the right configuration to get frequency  
control.

Is anybody running a similar setup who can make some suggestions? Any  
help is appreciated.

Thanks
