Don't let a few idiots put you off Linux.
Look into the linux...@groups.io mailing list (the home of Fldigi etc)
Lots of GOOD help on there, by many who remember our initial frustration
with it all. (Some Elecraft users there too.)
As to one OS vs another. Linux is different, that is all.
Do a
Don't forget ...
sudo apt install curl
on a command line, If you find it errors trying to get the firmware
updates from Elecraft.
Also, it's just:-
file kx3util
on a command line, from within the directory where the "target" file
(kx3util) is, to find out it's details.

I used to have this issue (KX3) - I don't recall if it went up or down (I
think down). I assumed that I was inadvertently pushing the microphone
buttons & subsequently switched the "MIC BTN" menu item to "PTT". I have
not had the problem occur again.

Robert is talking about the crystal filters, also known as roofing filters
now-days, that are typically placed after the first mixer (I mistakenly typed
"ahead" but I meant "after" as Robert notes), though there is a post amp and NB
before these filters in K2 and K3.
The idea is that a crysta
If switching from “MIC BTN” to “PTT” fixes the problem, then it must be related
to the way firmware reads the mic buttons. it could be that we need to tweak
the A-to-D thresholds a bit.
Anyone who has this issue could use the “PTT” setting as a work-around,
assuming they don’t require the UP/DN
Exactly right, Will. In the K3/K3S, we have a very strong mixer and post amp
followed by crystal filters at the first I.F., 8.215 MHz. Since the IF and ADC
are down-stream from these filters, they are very well protected from
out-of-band signals.
Our crystal filters are manufactured to very tig
Certainly not to disparage the K3(S) architecture (I have two of them) there is
nothing inherently wrong with an up-conversion receiver, if modern hardware is used.

Kind of a dumb question however here goes:
I got my K3S a short while ago and now I want to add the KPA500 and KAT500 to
it however it just now occurred to me that I should check how much juice I need
to power that thing!
I’m currently using an Alinco DM-330MV which I believe puts out 30A conti

Yes.

I am concerned about your so blithely talking about just changing the breaker.
The breaker is there to protect the wire and is sized according to the wire.
Do not increase the size of the breaker without verifying what the wire gauge
is. Quite likely if the breaker
I understand not to change any breakers. Roger that.
Thank you for the quick replies!

AND, if there's any sort of electrical fire and it is discovered a 20 A breaker
was installed with 14Ga wire, you fire insurance becomes instantly

That's Latin for "You're screwed".

Well, I just checked and switching MIC BTN to PTT has resolved the issue.
Thanks!
Looking more carefully, the frequency down-jumping glitch occurs on my KX3
about every 10-20 actuations of the PTT switch - the timing seems random,
but is often enough to be irritating. And it stops with the chan
