For just getting rid of key clicks, set your NB to t1-7 with IF OFF. This
was the prior best method for clicks before 4.51, but 4.51 has improved it,
and t2-7 is not needed except for really bad key clicks. t1-7 appears to
be good for 5 S units of suppression in 4.51.

Just guessing here, some elucidation on why you want to remote would be

There are some number of reasons to run the KPA and KAT (near where the
coax comes into the house?) in the basement. One is not having a long
ground attached to the amplifier, putting RF on a lot more of the house.
When working contests using NB, you should have the IF setting of NB set to
OFF. Only use the DSP NB settings. Unless of course you are bothered by
some impulse that only one of the IF settings cures. Alas, then you will
have to endure the extra junk that IF NB *must* create from strong close in

A K3 to K2 audio comparison changes a lot when 4.51 firmware is installed.
The change in the K3 was instantly noticeable.
So these days one must specify pre- or post-4.51.

There are a lot of engineering issues in a choice to do it with a unit

Hi Buck,
While the RF gain control results in digital advice being sent to the K3's
CPU, it is not an encoder like some other controls on the front panel. This
will not be a firmware issue.
The RF and AF gain controls are dual potentiometers. A standard voltage is
placed across the pot (the two e
Hi George,
A 13:1 SWR is what you might measure on 50 MHz looking into 50 feet of RG8
with NOTHING attached to the far end. From a reasonableness and efficiency
standpoint one should not plan anything more than 3:1 as a normal load for
a coax in coax out tuner. Less than that as frequency goes up.
Just a gentle reminder: the vast majority of issues are not in the Elecraft
equipment. Great gobs of personal time and frustration are saved by
looking FIRST to the mechanical, then third-party adjunct programs, then to
the manual (I know, I know, everyone HATES to read the manual).
If you are ne
Hi, Dave.
Well, there is one thing you did not do. A fourth condition, which would
be difficult, a lot more work given what you were doing. That would be
changing his syn first and noting the difference. It might be that the TX
change first would create a different middle picture in the series. B
Oh, that's easy to explain.
Overheard: "CW? What's CW? ... Really? ... Nobody uses that anymore. You
actually going to spend money on THAT???"

I don't know where others might come from, but for me running sound stage
diversity implies two IDENTICAL receivers each being fed to one ear.
Assigning a requirement that that all should behave normally when the
receivers are NOT identical seems unfair among other things.
Do we really want the ti
If one is going to upgrade one's K3 to the new synthesizer, then table any
QSK concerns until you have that in place. Just one of the benefits is that
the new synthesizer does state changes way faster than the old syn. RX/TX
state changes are what QSK is all about.
Besides the new syn, there have
Lot of folks get in here and complain about stuff. We just need to

It's Eric's list.

I suspect the denial is at your end, not Elecraft's. Make sure the
directory you are FTPing *into* allows you access. Make sure the target
directory is still the correct one. If it is, try running the Elecraft
utility "as administrator".

Well, here it sits, staring at me. Unassembled. From receipt bought it in
2009.
Excess to needs since have had an XG3 for a while now.
$75 shipped USPS to CONUS. New XG2 goes for $90 plus shipping.
