KX2 tx low power on 80M SSB

Reed Fite
Dave, try doing the Calibrate Transmit Gain that is in the Utility under Calibration. I had that exact problem in the 80 & 10 meter band. Tech at Elecraft told me to do this. That fixed the problem.  I had to do this several times & found it worked better on a old dummy load than it did on one I built from Elecraft.   The old one was not exactly 1:1 on the 80 & 10 meter band. Don't know why that made any difference, but it did.

Thank you to Nate W1NAT and Reed W4JZ for your quick responses to my post. I
have carried out the TX gain calibration as you have both suggested and that has
fixed the problem. I now have the correct power output on all bands from 80
through to 12M. 10M is still a little low initially (about 4W) but the power
comes up with brief CW carrier or just as I talk on SSB to 10W. I can live with
that as I don't use 10M very often.

Thanks Dave VK4FD

Great to hear, Dave!  

I’ll be posting the outcome of my KX2’s trip back to elecraft, so watch the reflector if you’re interested in following along.  As of now no ETA from elecraft, it’s been there about 2 weeks so far.
