Ed,
Since those easy steps did not reveal the problem, you will have to
resort to some Transmit Signal Tracing to find the problem.
Use the stage-by-stage points shown in the manual Appendix A page 14
starting at the middle of the left column.
BUT you will have to deviate from the instruction to set the K2 on the
40 meter band - use a failing band instead.
If the measured RF voltage is greater than the expected value, that is
OK. What you are looking for is the 1st stage in the sequence where the
RF voltage is significantly *less* than the expected value. That is the
output of the failing stage.

Hello Don,
Thanks for your reply. After setting the ATU to CALP 10 and 12m are still
dead, the other bands are fine. I do not have the 100W option installed.
