No, but I use a blue-tooth connected headset and it works great for moving
about the shack whilst chatting (VOX on)!

It works far better to simply call him. He almost always answers.

An even better methodology for determining if the power, antenna, and
propagation is good for the type of operating you do is to use the wealth of
internet-connected receivers around the world to see how your signal
compares to other signals received in that particular geographical area.
At the K9ZC station, we have antennas and feed line that are more than 2,000
feet from the shack. I used surplus (new) 1 5/8 feed line for the RF and
direct bury fiber optic cable with converters for the control signals.
Works like a charm.

Let me say this more clearly so there is no misunderstanding... you only use
one of these per load center. So for example, I have three 200 Amp load
centers in my house with 40 breakers each (600 amp feed to the house). I
use one of these per load center, for a total of three. It cost me a
Well Antenna theory and operation, like the rest of physics, always hold
true (nuclear blasts don't count)... so the more radiating surface (wire
length or tubing surface) you can get in the air... the better. There is
also a convenience factor, meaning whatever it is needs to tune for the band
This sounds good on the surface, but has the potential to be a disaster.
New end-of-spool heliax is fine. BUT...Avoid used heliax like the plague
unless you have the equipment to scan it (like a good Time Domain
Reflectometer). The longer the heliax is on the tower, the higher the
percentage
Seriously? Asking the Elecraft reflector if the K3 is a fun radio to
operate is like asking drug addicted people if they like drugs.

Again, Sam, K9SD has made these for years for several different radios. I
have one for my 781 and I spoke with him before Christmas about one for my
K3. He has a new email address. Anyone can contact me via email for it (I
don't want to publish it on the reflector).
Dr. William J. Schmidt -
Mine does the same thing except only when the PR6 (six meter preamp with the
ON control jumper in the correct position for the K3) control is plugged
into the ACC jack. I surmise that that possibly D4 (the diode that was
added for the reported MOD:
My wish is for an Ethernet connection. I'm actually working on a retrofit
to my radio right now using an embedded solution, but it could easily be
build into the I/O board. I'll share it when I'm done.

inside the DE15 connector - maybe something is shorting
pin 8 to ground inside there.

So I connected my PR6 - 6 meter preamp to my K3 for the first time last week
and work some DX. At the end of the day I go to shut the radio off and the
display goes blank (hear the relays disengage) but all of the LEDs are still
lit on the radio. and it will not turn back on except to cycle the
