Good Evening,
A few days ago I noticed a path through the trees which would let
one leg of my antenna rise about ten feet. Once I started it was more
work than I had planned. I had to drop the other antenna just to move
the first one. I was able to walk that leg out at right angles for
HI all, I've just been wiring up my W2 wattmeters... and neither one
is recognised by my win 10 computer.
The USB to 3.5mm plug Elecraft cord works fine with my K3... on com28
But the W2 utility keeps sending ": " at 9600 bps
and will not provide the current software level. with 1.0
As the K3S has been discontinued, looking over the “Parts and Mods” I see
“E100719 Bracket KPA3A” listed. Having recently upgraded from 10W to a 100W
radio by adding the KPA3A kit, I don’t see this bracket in the instructions,
nor find any instructions for its installation.
Anyone know what
There is a lot of antenna misinformation on this list. Your initial
assumption is basically correct. A vertical does not have low angle
radiation unless you have a perfect ground, it will then low
pseudo-brewster angle which is very effective. A 1/2wl or higher 40m
dipole is actually a
I use KX3 for wsjt-x and JS8Call. I just connect the KX3 audio
(headphone jack) to the USB sound card. I use the waterfall to "hear"
what is going on and I like the quiet. I have not noticed hum. I have
a few snap on toroids on the audio lines in case. I use 12" audio
cables from the KX3
I’m selling my Elecraft K3s SN: 11265 with the following options:
KPA3A100 watt Upgrade
KAT3AInternal ATU
KBPF3A General Coverage Receiver
KRX3ASub Receiver
KFL3B-FM 13 KHz Filter on Main Board
KFL3A 6 KHz Filter on Main Board
KFL3A
I would add the following comments.
You can easily reach the point of obsession with antennas, and some of the
choices involve heavy expense, tons of room, tolerant neighbors and a lot of
maintenance.
I think the Yagi antennas are among the best choices, by their nature they
concentrate
Right.

As a supplier of components, it was often true that it was difficult to
get designed in with a sole sourced device, but that "rule" was violated
over and over again. Sometimes customers were blindsided by design
engineers who somehow sneaked sole sourced devices into their system

As far as a vertical mounted on solid rock, ever heard of
radials? Almost all analysis shows angle lowering by copious
addition of radials to a vertical. I suggest You find the QEX
articles written By Rudy-N6LF which studied radials
thoroughly. Even with very short radials my 630m
