Well, after doing tons and tons of checks on the KPA100, I decided to take a break and build the PC interface cable and test the built-in KIO2. It works flawlessly, as expected. One thing that I did note: K2 Remote "assumes" that all K2's are QRP. No real big deal but, it would be cool to be able to "accurately" control power out with K2 Remote. 73 de John - KC4KGU K2/100 #2490
