William,
It is beginning to look like either the tuner or the antenna is the problem.
Don't overlook the possibility that something has come loose or shorted
in your antenna. Baluns can go bad, especially if they get moisture inside.

I do agree with that *and* if the band is 40 meters *and* if the KPA100 is

Knut and all,

Hi all,
I can think of one other *possible* explanation, although far fetched. If
the K2 transmitter has excessive harmonics or parasitics, this could happen.
The out of band energy is readily absorbed by the dummy load but not by the
tuned load presented by the LDG tuner. The antenna analyzer sho

William,
Thanks for that clarification. Connect the KPA100 to a good dummy load and
do the wattmeter alignment and calibration as indicated in the
KPA100 manual page 48 - see the SWR Bridge Null Adjustment and also the
Power Calibration sections.

William,
Are you reading the K2 display correctly when you do a TUNE?
Normally the K2 displays the power on the left and the SWR on the right.
The power is normally 20 watts and the SWR will be shown as 2 digits
(1.0 through 9.9).
In other words, you will see something like "20 1.0".

Hi group,
Perhaps it's a silly question, but i don't understand something.
I have a K2 100 watt but I don't think any other set will make a deferens.
the set is connected to a tuner (AT-100Pro LDG) and it tunes as far as I can
see ok.
But now what I notice, when I tune the tuner tunes to
