Can I use the key line interrupter (KPAK3AUX) between the K3 and the
ultrabeam controller? I´m looking for a way to protect the beam( keying
while elements are moving) without buying a microham device(rather
expensive), or is there another way I could go?

Take a look at the Portable Dipole in the Articles section of my website
at www.ad5x.com. It is the size of a 20-meter dipole, but can provide
resonant 40-10 meter operation. Very compact, cheap, and works well. It
has been my portable antenna-of-choice for several years now.
I also show
*How about an Elecraft mobile with remote head with coverage HF, 6, 2 and
70cm with 100W output on HF - 6M and 50W on 2M and 40W on 70cm?
The current offerings are of questionable quality and performance but many
operators own these types of radios for mobile and or backup shack
transceivers etc.
Thank you Mike.
I would get the four band module if it had 10m (I might still). I have a PAR
end-fed dipole for 40/20/10, so it would be great to use the same antenna for
three bands. I have seen that 10m can be done on the K1. I guess that with a
wire and ATU I could cover four bands...

Gil,
You cannot do both 20 meters and 10 meters on the 4 band board. The Low
pass filter for the 2 higher frequency bands is shared, so if the LPF
were to pass 10 meters, the 2nd harmonic of 20 meters would not be
suppressed.
If you use the 2 band board, the Low Pass Filter is dedicated to a

I have found that the 10 wire ribbon cable, part # E850479, is made wrong. The

Thanks for all the answers ... No, totally different. I use the KX1
paddle and it works fine. I tried out the KX3 paddle at last year's
Pacificon and was really impressed by the feel.

Actually I think the KX3 is an ideal candidate for HF-70cm as a
mobile. The KXPA-100 will handle HF-6m as a trunk-mount and the
KX3-2M extends operation to 2m. I am hoping we can convince Elecraft
that a 70cm/50 MHz transverter would find a good market. I can see

My KX3 is done. I finished it this morning much to my wife's dismay at
4:30AM.
The build went well, only difficulty was my old fingers and working with #2
screws and standoffs. I was missing about half dozen screws, all #4 of
varying lengths. But my trusty K3 'leftovers' came to the rescue.
The 'block' is usually rubber plug and can be removed. Use a pointy thingy to
pry it up a bit and remove with tweezers.

Hi all,
I've got a K2/100 that was damaged a while back in a close lightning

including the serial port on the K2. All other K2 functions have been

Mike,
Check the secondary menu to be certain the PORT parameter is ON.
Since you have signals on the RXD input of the MCU,
What software application are you using to test the K2 interface? Any
chance there is a problem with that software?
What is the health of the serial port on the computer.
If the Ultrabeam controller provides a PTT interrupt circuit you can
use the KPAK3AUX Key Line Interrupter to disconnect the Key line in
the KPAAUX cable and route Key Out from the K3 through the Ultrabeam
controller to the PA Key jack on the KPA-500.

Hi Chris,
To add to Joe's answer, if the Ultrabeam controller does not an interrupt
circuit built into it you could use the N8LP Tuning Relay.

Don't know about the PR40 but if it is an electret mic you will need to turn

Quite sure the PR40 doesn't need bias. Looks like you have it on. You should
