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 to "peak" the setting looking at that. Worked great. Once
I had seen your post, then tried that, and saw the numbers that I was
getting, I was confident I had nothing to worry about.

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.

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 connected to my MFJ-949E with internal dummy load,
and I connected so that the manual controls were in line, and adjusted
for minimum SWR while hitting the tune button. When I did this and
used the internal power meter, it showed 12w.
None of my measurement setups were perfect, I was mainly looking at
the spread of the readings. But when I used the setup described
above, all my readings, on all bands, were above 12w. When read with
external power meters, they fluctuated quite a bit more.

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 low pass filters that are not coordinated to the 10 Meters
Caps, if you can get my drift. I can't come up with a reason for
this. In fact, it may make 10 Meters useless for some modes.
Help?
