Mike,
There is very little change in current for the low level stages between
receive and transmit, but the RF amplifier stages Q5 thru Q8 draw more
current in transmit.
Have you checked your power supply to make sure it is not producing
ripple or low voltage during transmit. A low power supply voltage will
increase the IMD significantly.
Check the power supply connections as well. Monitor the voltage the K2
sees during transmit by using the K2 display function rather than
measuring the power supply voltage directly.

Don,
I forgott to mention that I do not have the k60xv option but that hade been
a nice way
to rule out the powerstage.
I wonder can there be any circuit that draws more current in Tx then Rx
and causing rippel on the
dc voltage during tx but not rx due to a cap that has lost capacitans?
Have replaced all el. caps. on the ksb2 board but not any on the other
boards.
