Why the difference, they are all the same rig why would it change from
rig to rig?

Jeremy and List;
Your KX-1 turned out better than mine. My 10 MHz band is weak and noisy
on receive plus I had the following transmitter problems:
I had 4 watts/7MHz and 10 MHz, 2.6 watts/14 MHz at 13.8V; 1.4
watts/7MHz and 0.8 watts/14 MHz at 9.0V.
I've tried the changes in R11 and R30 to increase power output, however
this just increases power and does nothing for my 14 MHz power roll-off.
Mine obviously does not meet spec and it is good to have suggestions on
what to try next from Elecraft. I've heard of people getting 4 watts or
more, nearly flat across all three bands. That power rise on 14 MHz at
9V does sound odd... I would have guessed it to be around 1 watt. Is
your power supply at 9V delivering enough current or is there a voltage
drop- possibly preventing a relay from opening/closing and changing the
specs of the RF filters on the PA?... A guess.
