I said earlier:
Rick claims that when using a series connection of two different transmission
lines, one coaxial, one window line, changing the length of one (coax) affects
something or the other, while changing the length of the other portion (window line)
has no effect whatsoever.
This is
I'll restate: The length of coax should be as short as feasible because the
losses from mismatch (SWR) are highest when compared to window or ladder line.
The shortest distance from my rig to the choke is about ten feet unless I bring
the window line inside (too problematic) or put the rig in

Kits are not subject to the EMC requirements and therefore do not have to carry
a CE mark. If asked, just show the invoice and a copy of the

You can google it and download.

The gain of the sound card (the volume) can be changed by the driver so even

Don't forget that not only do you need a combiner on the output,
but also a splitter for the input.
A couple of dB here and there and you soon lose most of that gain you got.
Better yet, look at the SPE 1.3K-FA.

You cannot tell the K3 to change it.
The Signalink is a mono soundcard and only listens to the left channel -
which is the connection to the tip of the jack. Even if the Signalink
cable has a stereo plug, there is nothing connected to the ring.
If you need to listen to the SubRX

Before attempting to use the EMU-0404, check your application. If it

The real answer here is that the K3 always indicates the carrier frequency.
There is no shift on SSB.
When changing from SSB to CW, the receive frequency is shifted by the
amount of the sidetone pitch.
The result is that the CW signal is now at an audio frequency of zero,
which neither your

One thing to try is to tuck the ribbon cable and speaker cable to the

to route those wires as far away from the KSB2 board as possible.

David,
The bearings in the encoder should be able to handle the added weight of
the knob.
However, there is one caviat - some users of that knob want to mount it
with no drag on the knob so they can spin it. That means that there
is no contact with the felt washer, and the weight of the knob
Richard,
The K2 (and K3 and KX3) control power using a closed loop system. That
means there must be some means of measuring the actual power output
right at the antenna - that measurement is compared with the power
requested by the power knob in the MCU, and the drive is adjusted as
required
Thats exactly how i did it. I'm actually using both felt washers on the VFO A
and one on VFO B.
I have the regular (all black) knob set from 73cnc.com (couldn't wait till
Dayton to get the deluxe).
But they are great.

Hi Joshua,
I recommend the ATU. Very handy for wire and vertical antennas in the
field, and for non-resonant antennas at your home QTH.
The MH3 (shown as H3 on the KX3 page) is an accessory, but not
included. You would have to order it separately, as with the ATU.
Many KX3 ops prefer the kit.
Joshua,
In keeping with the Elecraft philosophy of not requiring the customer to
purchase any more than is desired, the KX3 microphone is an optional item.
Certainly a microphone could be provided with every KX3 if the price
were 'bumped up' by the cost of the microphone. But that is not
