Hello,
If the weather clears and the rain stops I should be out on the AT near
Shartlesville, PA about 1 mile south of Rte 183.
I will be operating in the NE QRP Club's QRP Afield contest for a while.
NE QRP #629

Hello,
Change of plans since the wx is not going to cooperate.
I will hike about 5 miles East of Rte 183 to a shelter for cover from the
rain. I will be between Strausstown and Hamburg, PA.
I will be using my K1 @ 5 watts and the Black Widow Vertical.

I have a K2/100 with a KAT100. For the most part, all works well as
expected.
Intermittently, though, when I press the TUNE button, the KAT100 will
chatter briefly as if finding a match, and then it suddenly stops and the K2

If it is RF feedback, the proper way to deal with it is at the source - in
your antenna system.
An easy way to check it is to cut a quarterwave wire for each band that is
troublesome - attach one end of the wires to the ground terminal on your
tuner and the other end just stretches out and
In this case the antenna is a simple coax-fed 40M dipole with a balun at the
feedpoint. Without the KAT100 in line the SWR is approx 1.2 to 1 at 7100
where the problem occurs.
A quick check shows that yes, the problem seems to occur only on 40m. I
also noticed that other accessories on the
Here is another simple explanation. Perhaps it is voltage drop on
your power supply. You probably have the best match and most power
output on the 40m band, Is your power supply up to it? A simple way
to test this is to turn the power out down by 30W or so. Not enough

Raj,
Fine analysis, but consider that the K2/100 has more gain and better
efficiency on 40 meters than on most of the other bands, so the current
drain on 40 meters should be less for any given power output level, and
under normal operating conditions, the current drain should be at a minimum
on
Jeff,
Let me add my 2 cents worth:
First, if you have been attempting to align your filters by trial and error,
you may have the wrong sideband set.
Secondly, a shift of 20 Hz or so is to be expected because of the DAC
resolution - if your shift is any more than 20 Hz, it can be corrected by
10 matches
