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.

Enjoyed putting my KX1 together and tuning around the bands but when it comes to transmitting, I'm wonder if something is slightly wrong or no. Power out: 13.5v: 40m = 3.8w (39ppv), 20m = 3.06 (35ppv) 9v: 40m = 1.32w (23ppv), 20m = 2.25 (30ppv) The 9v 20m output is strange to me. Have checked current draw yet, I gotta get some sleep (built all last night, 6:30am here now). Any ideas?
