I find I have a place for a 6 meter beam. I don't have one but would
like to make one if feasible. Does anyone know of good plans for a 6
meter beam that would be realistic to make?
Might as well use the 6M ability of the K3

Hi Richard,
In my opinion you have not installed the APP's correctly. I used them on my
K2, my K3 and all over the shack. I have used them mobile and on the bench.
I have even used them holding the K2 in my hand while I transmitted on SSB
to test a portable aerial. I have never had a problem
Hi Gary.
DK7ZB (http://www.qsl.net/dk7zb/start1.htm) has a lot of good designs.
I recently discovered the new promising design of G0KSC
(http://www.g0ksc.co.uk/) and I plan to change my DK7ZB yagis to the
design og G0KSC.

Hi Gary,
What length of boom would be practical for you?
In Canada I used homebrewed yagis on 6m from 1956 onwards, singles and
stacked, which were not difficult to build, and if I still have the
construction detail for the 6 el yagis on 24ft booms I could send it to you,
if 24ft is not too
Richard,
you can get this connector in different versions. The 2,1mm and 2,5mm look
very similar, bat of coarse they are not :-)
If you by accident use a 2.5 type it will result in exact the problem you
describe because the K2 Jack is 2,1mm

Hello Richard,
What you're describing is not normal. Are you saying the plug pulls
out of the socket with very little effort? Or does it fit snugly, but
the connection drops out as you move the cord? If the plug fits very

I've been using the Route 66 OWA antenna by W4RNL (LB Cebik) and it's worked
out quite well for me. The driven element is a dipole and there is no matching
structure (gamma / tee / balun) required. Just type in W4RNK in google,
establish an account for the site and then go to
Funny, I found myself searching through the menus, looking for the VOX
Delay, and found that it is right on the front panel.
Push and hold the Speed/Mic knob. In CW mode, it is the semi QSK delay.
In SSB mode, it is the Vox delay.

Yes. That's exactly what I am doing. When I would flip my K3 over onto its

It's not a link to a zip file directly.

The Elecraft utility shows the same version numbers for the 3.79 beta as
