Craig,

Since you have decided to include the external interface, AND you only have one USB port, look at the serial port on your chosen interface - you may need the KX3SER cable instead of the KX3USB cable. The interfaces I know about all have serial ports to connect to the rig and not USB ports.

Thanks for the feedback and advice, Don.

I have the Elecraft cables and figured that it would be worth buying an external interface unit that has a built-in sound card capability that I know will work, vs. take a chance with the MS Surface Pro computer. (The unit is reasonably compact and light.)

The optical isolation circuits in the interface unit may be even more important at the St. Lucia sites, especially considering the various power sources that will be used. (I too am a believer re. having isolation circuits.)

Also, the Surface only has 1 USB3 port on it and it would be good to not have to use an external port expander unit to accommodate more cables, etc.

So far--it sounds as if I can get there OK with this path.
