Hi, Ed,
I don’t know if I have any helpful input, but I have some input nonetheless.
First of all, what type of batteries are you using? Have you measured the
voltage of your battery pack under load? That would be my first
troubleshooting step.
Secondly, I have noticed on my KX1 that 20M
The KX1 I just bought and built, #2219, is hitting 5W on the external
12vdc PS. This setting returns 1.5W on 40M, when using the brand new
AA internal batteries.
If I set it to 4W with the 12vdc supply then, when I am on the internal
battery pack I only have 1W on 40M and 500mW on 20M.

My query is answered.
I found the answer buried on page 72 of the current KX1 manual. It
states Maximum power output from the
final stage (Q6) is about 4 to 5 watts, depending on the supply
voltage.Q7, in the receive band-pass filter, limits the signal
voltage that can reach the receive
3 matches
