I have one of the custom machined VFO knobs from 73cnc.  It is in perfect
condition and is one of the later versions.  It is a real treat to spin and
very classy looking; a great way to "cusomize" your K3/K3S.  While these
knobs are shown on the website
(http://www.dtsohio.com/73cnc/elecraft-k3-black.html), I'm not sure if they
are currently being produced and for sale.  In any case, these knobs listed
at $105 plus shipping.  I am selling my as-new know for $70 including
Priority Mail postage to any US ZIP code.  Please contact me off list at

Re: [Elecraft] KPA500 - KAT500 stopping K3 boot

[Dick Dievendorff]

KAT500 sleeping (12v supply connected, power button "off") is fine.

The problem occurs when the KAT500 has no 12V power; it pulls down the AUXBUS 
pin. 

K3 MCU firmware was changed to display a reminder if the AUXBUS is held low for 
too long during startup.

From K3 firmware release notes:

MCU 4.93 / DSP 2.83, 10-16-2014

* KAT500 POWER-ON REMINDER ON K3 DISPLAY: If a powered-off KAT500 is pulling 
the auxBus signal low when the K3 is first turned on, "TURN ON KAT500" is 
displayed. Previously this condition would lock up the K3 without explanation

Is there an issue with the KPA500 being OFF with power up -> booting of the K3? 
 Does it need to be actually powered up, i.e. and in operational state?  OR is 
just having it in the “sleeping” state (REAR switch ON, FRONT PANEL SW-OFF) OK?

I know about KAT500 and AUX-BUSS stopping K3 bootup, and have an “automatic” 
solution that works great.

Re: [Elecraft] KPA500 - KAT500 stopping K3 boot

[Jack Brindle via Elecraft]

Check your cables. It may be that you are using a straight-through cable with 
the power pins connected between the K3 and the KPA. These two pins (pin 8 on 
both sides) must not be connected.

[Elecraft] For Sale: K144XV 2-Meter Option for K3 or K3s

[John Reilly]

Recently bought a used K3s with the 2-meter option factory installed, 
which I have no plans to use. According to Elecraft, this is compatible 
with K3's above serial number 3000, and all K3s'. The K3s went to 
Elecraft in Jul 19 and got a complete checkup, including the 2-meter 
module. I tested it with a dummy load and it appears to work. This will 
include all the parts I removed from the K3s, as well as a KFL3B-FM 13 
KHz filter. The price has been adjusted a little lower in the event you 
need to order some additional parts. PayPal preferred. $375, including 
USPS shipping. John, N0TA

Re: [Elecraft] KPA500 - KAT500 stopping K3 boot

[Mark Musick]

Ben,
You no longer have to worry about the KAT500 stopping the K3 power on. That was 
fixed in a 4.xx firmware update eons ago. If you have a 5.xx firmware version 
in your K3 you have nothing to worry about.
As far as I know there never was an issue with the KPA500. I never had any 
issues with my KPA500 and after loading the updated firmware no issue with my 
KAT500 either.

Re: [Elecraft] KX3 and JS8CALL

[Jim Brown]

Thanks. I knew Allen Burdick, who died quite a few years ago. Bill 
Whitlock and I still serve on the AES Standards Committee, and are 
principal authors of AES Standards on EMC, and I've been Vice-Chair of 
the EMC Working Group for about 15 years. The first draft of four of 
those Standards started out with Neil Muncy and me around my kitchen 
table. Bill and I have taught EMC workshops together. Bill is far more 
than Deane's protege -- a fine engineer in own right. Deane was a fine 
engineer, and published some important work before he died.  Bill, Neil 
Muncy, and I were elected Fellows of the AES, partly on the basis of our 
EMC work.


I retired about ten years ago from a career that started in broadcasting 
and ended in pro audio. When Neil Muncy died, I was asked to take over 
the EMC workshops that he had taught for many years at conventions for 
sound contractors, and continued that until about four years ago. Slides 
and a White Paper are on the pro audio section of that publications page.

Excellent and comprehensive info on your website! Everyone should take

In my setup, the power supplies for the KX3, Raspberry Pi and powered 
speakers are the typical 2-wire, no ground, switching supply in a 
plastic case, so ground potential is established through the audio 
interconnect. The rig and computer connect only through the USB ports 
for the USB serial adapter and the USB audio interface. After a little 
experimentation, I realized The “hum” I was hearing was RF getting 
into the powered speakers on transmit with the antenna I close 
proximity to the KX3. Moving the antenna away from the rig resolved 
the issue.


This is a little off-topic, but may be of interest to the audio geeks 
on the list...
I worked in TV engineering here in Nashville for many years, and we 
dealt with a lot of music recorded in big studios, and thus long cable 
runs and a lot of channels of audio. It was all analog in the early 
days and several audio engineering luminaries helped me immensely. One 
was Allen Burdick of Benchmark Media Systems. His “Clean Audio 
Installation Guide” is still indispensable:

[Elecraft] Special BNC adapter/barrel

[Charlie T]

I have available, a small quantity of a very useful, but slightly different  
BNC "T" connectors.
Just picture a normal BNC "T", but with the male end swapped with the one of 
the female ends.

What makes this useful is that with the male end plugged into your K2/K3, a 
right female points up for your loaded whip, AND the other female, straight 
across from the radio's connector can have a  BNC to two pole banana adapter 
for easy connection of a counter-poise or ground wire.

I can supply these at $10, shipped anywhere is the US.

Re: [Elecraft] AX1 Loaded Whip Antenna - Elevation and

[David Gilbert]

Well, I actually have three reasons why I think the root of this 
discussion has been misguided:


1.  Typical portable operation is for casual fun while camping or just 
enjoying the outdoors.  Squeezing out every last dB doesn't quite fit 
that scenario.


2.  If you are trying to squeeze out every last dB for whatever reason, 
using an AX1 with 50 feet of coax and an extra tuner isn't the way to do 
it.  There are better choices for the same size and weight budget.


3.  And if you are using the AX1 with its very high Q, there are lots of 
other variables (length of counterpoise, terrain, height above ground, 
proximity to other detuning influences, etc) that will have far more 
impact on transmitted signal strength than a couple of extra dB loss due 
to SWR on the coax.  Wayne made pretty much the same comment in the 
context of SWR, but the same holds for signal strength.


Use whatever you want.  It makes no difference to me other than the 
misconceptions that come with it.  I've done a LOT of portable operation 
over the years, and my first priority has always been to put up the best 
antenna I could within whatever constraints I had at the time.  I don't 
own an AX1 but it appears to be a fine antenna for its intended purpose, 
which was essentially a backpacker antenna usable even for pedestrian 
mobile.   However, if I was on a camping trip (tent, cooler, etc) and 
wanted to get out better, I can think of better options.  I do own a KX2 
and I use it with a homebrew 20m vertical that I can easily carry in one 
hand for miles (five 4' sections of lightweight tubing, one of which is 
for elevating the radials) and set up in fewer minutes than I have fingers.

Dave And All,

  


Hmmm!  I don't quite understand that statement.  Why would you worry about
every dB at your home station but not necessarily be concerned on a portable
setup???  I guess maybe you are saying that, when operating portable, just
get the best antenna possible as opposed to a lesser one.  Well, that's
ideally true, but "you do with what you got"!  Whatever antenna you might
have for portable use, you want to squeeze every dB you can out of it!  I
tend to think it could be even more important when operating portable since
you already apt to be weaker, and that last dB may be the one that gets you
heard!  Home station operators might  actually ignore such issues since they
may already be more than loud enough to be heard.  QRP/portable operators
tend to not have that luxury.

feet vs 30 feet), and while I will be the first to argue the benefit of

every single dB for normal station operation (see

http://www.ab7e.com/weak_signal/mdd.html), I don't understand the angxt

over that 3 dB for portable operation.? If that's actually a concern,

bring a better antenna.

Re: [Elecraft] KX3 and JS8CALL

[Michael Arnold]

Jim,

Excellent and comprehensive info on your website! Everyone should take a look 
at it.

In my setup, the power supplies for the KX3, Raspberry Pi and powered speakers 
are the typical 2-wire, no ground, switching supply in a plastic case, so 
ground potential is established through the audio interconnect. The rig and 
computer connect only through the USB ports for the USB serial adapter and the 
USB audio interface. After a little experimentation, I realized The “hum” I was 
hearing was RF getting into the powered speakers on transmit with the antenna I 
close proximity to the KX3. Moving the antenna away from the rig resolved the 
issue.

This is a little off-topic, but may be of interest to the audio geeks on the 
list...
I worked in TV engineering here in Nashville for many years, and we dealt with 
a lot of music recorded in big studios, and thus long cable runs and a lot of 
channels of audio. It was all analog in the early days and several audio 
engineering luminaries helped me immensely. One was Allen Burdick of Benchmark 
Media Systems. His “Clean Audio Installation Guide” is still indispensable:

Deane Jensen of Jensen Transformers fame and his protégé, Bill Whitlock, were 
two others:

And a local genius, Dave Harrison, who designed an built the legendary Harrison 
Consoles that we used extensively:

Power line hum and buzz can be prevented by 1) getting power for all
interconnected equipment from the same AC outlet, or from outlets whose
Green Wires are bonded together, AND 2) bonding from chassis to chassis
of all interconnected equipment, AND 3) proper bonding of all grounds in
the home, including ground from that interconnected equipment in the
shack. All three are necessary. There's a tutorial on this at

[Elecraft] KXPD3 for sale

[Jim Leder]

I could never get used to the KX3 KXPD3 paddle, so I bought an AME Porta Paddle 
(much better for me). I am offering my KXPD3 for sale, complete with original 
data sheet, both hex wrenches, and the 2 extra springs (firm is installed). All 
is in the original zip bag. The wire mod has been installed (errant dit issue).
It’s a good little paddle, just not for me.

Sent to you for $85. Paypal ok.

Interested? Email me.

Thanks and 73…

Jim Leder … K8CXM

I suspect that Wayne and Eric would take a big exception to the use of the 
Elecraft name in their obvious knock-off product.

Re: [Elecraft] AX1 Loaded Whip Antenna - Elevation and

[w7aqk]

Dave And All,

 

Hmmm!  I don't quite understand that statement.  Why would you worry about
every dB at your home station but not necessarily be concerned on a portable
setup???  I guess maybe you are saying that, when operating portable, just
get the best antenna possible as opposed to a lesser one.  Well, that's
ideally true, but "you do with what you got"!  Whatever antenna you might
have for portable use, you want to squeeze every dB you can out of it!  I
tend to think it could be even more important when operating portable since
you already apt to be weaker, and that last dB may be the one that gets you
heard!  Home station operators might  actually ignore such issues since they
may already be more than loud enough to be heard.  QRP/portable operators
tend to not have that luxury.

[Elecraft] Questions for Remote operation with the K4

[tobestep .]

Hi Wayne:
will I be able to totally eliminate the use of the RemoteRig boxes with the
K4 when operating remotely? Will I need specific software for remote
operation for win10 PCs? Will I be able to control and monitor the KPA1500
directly through the K4?

Re: [Elecraft] K4 60m band

Why not?  K3(s), KX3, and KX2 all support 60M band. 

And,K4 has continuous coverage from 100KHz to 54 MHz.
