[Elecraft] K1-4, KAT1: low output on 30, 40, no match on 40 (Part I)

[Randy Tompson]

I'm hoping someone here might have had a similar issue, and save me some
time.

 

I recently installed a KAT1 into my K1-4.  I have 40, 30, 20, and 15 meters
installed in the K1.

 

Symptoms:  low output (0.1w) on 40 meters and 30 meters.  KAT1 will not
match to 50 ohm dummy load on 40 meters.

 

I have cycled through the ATU menu, checking the SWR reading on each band,
for L0-4 and C0-5.    I'll post the results in a separate email.   The
relays are clicking on each band change, and for each L and C change.  The
pattern wasn't clear to me;  does this point me to C5?

 

The unit was working properly after KAT1 installation.  I.e., the problem is
new.

 

I've reheated the KAT1 toroid leads, thinking I might have a cold joint.  no
joy.

 

Does this ring any bells for anyone?  

 

Many thanks, and 72.
