Folks,
I'm having a real struggle getting 6 to 7 WATTS on 28 Mhz while all other all
other bands come up with a number well in excess of 10 Watts.
Has anyone experienced this problem and was able to solve it? I'm suspecting

Bill,
The most common cause of low output on 10 meters is T2 - be certain it
is wound exactly like the illustration in the manual (except for the
number of turns in the illustrations which may or may not be correct).
The second thing is T4 - be certain it is wound as instructed in the
If all else is well, then consider how you are measuring it. As Don has
pointed out before, the internal power meter expects a 50 ohm load.
After trying several configuration that showed 6w on 10m, I checked the
dummy loads. All three were showing 1.2 swr with an analyzer. I then

Dave,
That is an excellent method of achieving a 1:1 SWR with an unknown (or
questionable) dummy load. Thanks for the reminder. Just be aware that
the SWR=1 condition is frequency sensitive - the tuner must be retuned
if the frequency or band is changed.

That is absolutely right Don. I was playing with it several different
ways, and using the tune button and the manual tuner you could really
see it jump when you got it dialed in. The output of the power meter
on the K2 was considerably more sensitive than the meter on the tuner,
and was able
