[Elecraft] K1 Low Power on 20M band once ATU is installed...fixed!

[N2ZDB at aol.com]

Well it is finally fixed.  When I went to listen to the signal on my  K3 I 
noticed the frequency was off around 500 Hz or so.  Tried to adjust  the 
sidetone pitch and nothing happened - test mode audio was weak and frequency  
would not change with C13.
 
I moved C13 back and forth a little and the tone came in nice and strong -  
with a adjustable pitch.
 
Re-installed ATU and now a full 5.5 Watts on 20 Meters using a 3 cell Li-Po 
 (12.2 Vdc)!
 
Looks like a defective C13 or cold solder joint.
 
The owner of this K1 will be happy when he hears this news!
