Thanks Fred! Unfortunately, the KAT500 utility does not see my KAT500. Been doing exhaustive testing with Elecraft support and they've concluded that I have a bad circuit on the KAT500 board. I've tried two different cables (known to work with the 2 meter module), two different operating systems (Mac OS X and Windows) and two different computers (MacBook Air and iMac). They are sending me a replacement board so it looks like I'll be re-assembling the KAT500 later this week!
