          I understand.

          Perhaps the other radio is getting too much signal.  Another way
is to listen to K2's 20m second harmonic on 10m with the other radio, but no
more than S9.   To check 17m and if you can listen to above 6m with the
other radio, try K2's third harmonic 54.204 MHz up, again no more than S9.
This is a rough test to give you a quick check.

It would be a good idea to do two of these tests on each band,  One with K2
feeding a dummy load, and the second feeding the antenna, just in case on
20m and 17m there is a little RF feedback from the antenna or feeder.

          Good luck.
