Erik,
Yes, you can use paddles with the WinKeyer, and IMHO the big advantage of a
WinKeyer for this is that the paddles are integrated with computer CW. That
is, if the computer is sending CW, a touch of the paddle instantly stops
outgoing computer-generated CW so you can carry on with the paddle.
Mike,
The only person that would change the firmware would be Wayne Burdick
himself. In the K2 it would require replacement of the firmware chip
because K2 firmware is not downloadable like the K3.
You would likely have to pry Wayne away from his K3 MCU firmware efforts
to get his attention,
Sounds like a problem with the negative-voltage generator for the RS232
driver. Please contact customer support for a replacement KIO3 module,
and return the old one if you don't mind.

The K60XV will not provide any advantage for you with that IF frequency
