What is the value of R30? If you change out this 22 ohm resistor with a 33 ohm resistor you should see an increase in power out. Mine also had low power TX but after this mod it is up to where it should be. Check out the archives from this reflector on low power on the kx1 for more discussion on this issue.

It was suggested that I compress the windings on "L2" to about 70% of the core coverage instead of the 90% that is used. When this was completed my power came up to about 3 1/2 watts but YMMV de "rc" kc5wa _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
