[Elecraft] K2 fixed, but now what?

Hi Daniel: 

Using an end-fed wire you'll do better to add a "counterpoise" wire to
hold the K2 case at "r-f ground". What you need is a 1/4 wave long wire
for each band. Just connect it to the case of the K2 at one end and lay
it out along the baseboard or wherever convenient. Be sure it is
insulated, especially at the far end. It will the "hot" with r-f. Some
ops only cut counterpoise wires for those bands where they have trouble
finding a match with the KAT2, or those bands where the SWR changes when
they touch the case. 

The other thing you can do is change the length of your antenna wire.
I'm not sure what you mean by a "Low Angle" radiation wire. Any wire
antenna will give you a low angle of radiation if it runs vertically
(unless it is more than 1/2 wavelength long), or if it runs horizontally
as long as it is at least 1/3 or 1/2 wavelength above the ground. 

The KAT2 has definite limits on the range of impedances it can handle.
It sounds like you are exceeding them. Try changing the length of your
antenna  a few feet and see how it behaves.

P.S. Please don't SHOUT so early in the morning. I haven't had my coffee
yet.

BUT NOW THIS IS HOW I SET UP MY TEMPORARY ANTENNA THIS MORNING.  LOW
ANGLE RADITION WIRE 20FT RAN THROUGH MY WINDOW WITH WINDOW TURNED UP
AGAINST THE WIRE, AND THE END OF THE WIRE INTO KAT2 WITH NO GROUND.  I
GET HI CUR AND LOW P ON SOME BANDS. AND THE ELECRAFT RESETS ITSELF.

I KNOW I CALIBRATED/ALIGNED THE KAT2 CORRECTLY AND THE BASE K2 (CW ONLY)
PUTS OUT ITS FULL POWER ON ALL BANDS.

I THINK THAT MY PROBLEM IS NOW THE ANTENNA.  WHAT ARE YOUR IDEAS??

ON ANOTHER NOTE:
I WILL TRY TO BE MONITORING THE TWO AGREED UPON FREQUENCIES [21.332 &
18.132] BETWEEN 2PM AND 6PM.

DANIEL
