Hi Howard,
Too bad the guys who seem to design the Yaesu CAT interfaces don't seem to have
ever wanted to use one!

Actually, ICOM also has it's share of issues. If you want a good model for
how the CAT interface should work, check the Kenwood TS-450. We'll see if
Kenwood gets the TS-2000 right.

Feel free to steal my source code for controlling the FT-100. It is
available at www.amsat.org (InstantTune for InstantTrack) and it actually
works pretty well. I have used the FT-100 with a laptop in my car for 
satellite mobile contacts (using a cell phone while driving
is just not enough challenge!)

Except for the most basic functions, this ain't gonna happen...
