You're right, Andy  - I've heard from tops ops that own them that the 
TS590s are very nice rigs, and ARRL Lab tests show them much cleaner 
than ICOM and Yaesu. I've recommended it to several hams who can't 
afford Elecraft. (Although used K3s are getting to be a real bargain!).

[Elecraft] PX3 keyboard fix

[KG7WGX]

I bought a GMYLE Mini USB keyboard a while ago and tested it with the PX3 and
it worked.Then I put it aside and concentrated on my Morse speed and
learning to use a bug.Today it didn't show the "K" when I connected it. 
However, it did connect if the USB plug was pulled out around 1/16".I
applied a narrow band of heat-shrink to the USB plug and now I get a firm
connection, but the plug cannot be inserted far enough to disconnect.I don't
know if this was "tolerance stacking" and a special case or if it might
apply to other USB keyboards.If you are having intermittent connection
problems with a USB keyboard, you could try this before buying a different
keyboard.

Re: [Elecraft] K3 appears to be in AM even though mode says DATA

[Tom Azlin W7SUA]

Thanks Don.

I had changed nothing in the radio. Had been working just fine up to 
this afternoon! Not just the filter, the radio is in AM mode even though 
the mode says DATA.


Will go look at the filter set up!

[Elecraft] P3 REF LVL 160m Setting

[Jim McCook]

K3 owners know that the P3 doesn't memorize the REF LVL setting on 160m 
like it does on the other bands, unless the K3 is returned to 160m 
before powering off.  Does anyone know if there was ever a fix for this 
annoying problem?  73, Jim W6YA

AND, ( stated as kindly as I can) You'll wear out the manual before the

I was a Yaesu fan-boy, putting up with the seemingly endless menu's all

I'm cured now and am waiting to save a few buks on the K4Kit.
Guess I should probably sell my couple year old K3S package eh?

You get what you pay for. Yaesu has been making very dirty radios -- clicks
and splatter have been the rule. Elecraft rigs have always been very clean
on CW, less so on SSB, but nothing like Yaesu on SSB.

As others have posted, the convention was that Broadcast stations east
of the Mississippi were given W call letters and west of the Mississippi
were given K call letters (with noted exceptions).  Ocean-going ships
had the opposite according to their home port of registration.

When I started doing ship safety radio inspections in 1967 there were
600+ such vessels in the US registry, not counting the WW-II-era Victory
ships that were owned by the U S Maritime Commission and were being
pulled out of "Red Lead Row" (deep storage Reserve Fleets) and operated
under contract to support the Vietnam War going on at that time.  New
ship radiotelegraph stations will be licensed as part of the ship's
radio station license under the now-standard XXX call letters.

[Elecraft] K4 Pricing Posted

[Andy Durbin]

"You get what you pay for. Yaesu has been making very dirty radios --"

I'm not sure I see the connection between part 1 and part 2. I paid for a 
Kenwood TS-590S. Actually I have two of them. I don't think this radio ever 
sold for more than about $1,600 and to the best of my recollection it's not 
high on anyone's dirty transmitters list (assuming a Chinese TCXO was not 
fitted).

I have never felt I could have worked more DX with a "better" rig.  Better 
antennas - sure, better rig - no.  My flying sucks up all my money.  None left 
for K4.

[Elecraft] KXPA100 mounting screws

[stephen shearer]

OK, the manual says #8-32 no deeper than 1/8" into case... (page 10)

NOT true, my KXPA100 takes #10-32...  SO, is the depth into the case 
1/8" or do I have more???  bigger screw??


Yes, still 32 TPI...

Help.  so I don't screw it up.  Pun intended.

Re: [Elecraft] KX3 battery upgrade?

Hi Steve,

Yes, I would like to see this.  I no longer even bother installing the 
internal batteries but just carry along a Bioenno pack.


I have not heard of any 3rd party solutions.

On 10/5/2020 5:47 PM, Steve KC6ZKT wrote:
The KX3 is my favorite of my HF radios right now. But one of my

I always wind up carrying an external 6_Ah or 10_Ah LiFePo4 battery 
into the field when I use this radio, an external charge controller, 
and solar panel. It's not a big problem, but it also should not be a 
big project to improve this situation. The KXBC3 has enough real 
estate to include a lithium battery charger, and even a solar charge 
controller in its space. The amount of battery energy that could fit 
in-place of the NiMH cells could approximately triple the capacity of 
the AA cells.


So I have these questions:

1) How many of you out there might buy an upgrade which replaces the 
KXBC3 board with a lithium battery manager, and a associated battery 
pack?


2) Are there any 3rd parties already making anything like this?

Re: [Elecraft] OT: W vs K broadcast station callsigns

[Mike Morrow]

Another interesting fact about US broadcast station callsigns is that back 
before U.S. maritime radioTELEGRAPHY ended (except for rare historical 
exercises) in 1999, most US-flag merchant ships with radiotelegraph stations 
were assigned four-letter callsigns beginning with K or W.  There are no longer 
many such calls that are still assigned to merchant shipping.  A quick random 
search at:
  https://www.itu.int/mmsapp/ShipStation/list
found KPLB, WGDX, WQUI.  Twenty-five years ago and earlier there were hundreds 
of US ships whose radiotelegraph station had callsigns of broadcast station 
format.  Maritime radiotelegraph coastal stations like KPH, WCC, WOM used the 
same call format as some broadcast stations like KSL, WLS, WOR, WSM, etc.  
Maritime ship radiotelegraph callsigns were not affected by location for 
assigning K or W as first letter.

Forty years ago I held a commercial radiotelegraph license.  After I received 
ham call KK5F, I day-dreamed about having a ship with maritime radiotelegraph 
call KKHF to match.  :-)

Re: [Elecraft] K4 vs. K4D Question

[Chris R. NW6V]

Terry,

I could use your self-description by adding "used to" in the context of
contests (I'm up to 297 confirmed and contest opportunities for the rest
are slim to none).

Then I'd add: "lives on tiny urban/city lot surrounded by both horrible QRM
and hills."

My antennas were as you describe: a 2-el 5-band beam up a whopping 30 feet,
and a wire running through and around trees like a demented pretzel at that
same height. And you're right, while diversity thrives on differences, it
doesn't thrive on THOSE differences.

In my quest for DXCC on 40 and 80, I'd added a pair of DXE active receive
verticals and noise canceller in a failed attempt to phase my way through
the s5-s6 noise wall - there were far too many noise sources for
cancellation to be effective. So I was left with a receive antenna that
didn't work all that well in noise-hell, either.

Then, after letting it sit mostly unused for 6 months, I tried diversity
reception.

Wow.

When you're working down near the noise, QSB can kill many a QSO. But even
with my minimal antennas, the way signals "float" as the RF rotates through
polarizations is remarkable to hear: a signal that would otherwise be lost
often comes up in one ear just as it drops in the other...  I recently
worked VK6LW when he was unreadable on either the long-wire or the receive
ant, but was readable with diversity turned on.

It sometimes seems like the difference between mono and stereo music.

Anyway, diversity reception was unquestionably the key to 80M DXCC from
this QTH.

Point is: if my K3 hadn't already had that second receiver, it's unlikely I
would have added one just to try. So if you can swing the cash - like a
good scout: "be prepared."

Re: [Elecraft] OT: W vs K broadcast station callsigns

[hawley, charles j jr]

“Beginning with the introduction of licensing in late 1912, the standard 
practice had been to assign call 
letters starting with "W" to radio 
stations east of the Mississippi River. However, KDKA happened to receive its 
assignment during a short period during which land stations were being issued 
call letters from a sequential block of "K" call letters that had previously 
been assigned only to ship stations. Although the original policy was restored 
a few months later, KDKA was permitted to keep its non-standard call 
sign.[11]”

Re: [Elecraft] KX3 battery upgrade?

[Ignacy]

I never had a failure with Li-Ion batteries bought from batteryspace.com.
They are connected externally to KX3 and charged by an AC charger.   They
last so long that seldom I need to charge during a  trip. 
I use LiFePO3 for my 100W radio.

Re: [Elecraft] KX3 battery upgrade?

[Gwen Patton]

Since I don't have to schlep the thing on my back like those who backpack
to their field ops sites -- I use a dolly I keep in my van for the purpose
-- I use a Talentcell 12Ah 12v battery. I connected a coaxial connector
cable I got from Elecraft to it, and it powers a lot of my devices. The
only issue is that it's about 1.35 kg, so it would be a significant weight
to carry, say, in a backpack. That's one reason why I worked up my USB-C PD
smart cable, as the PD power bank I have for it is a lot lighter.

Agreed on all counts. I read more than two dozen email reflectors, and 
Thunderbird makes it easy to to sort each into its own mailbox. I've 
never used it to sort topics, but agree that the Subject Line is the 
ideal sort range. I use subject line sorts to sort to the mailboxes.


Thunderbird is very versatile -- it can be set to read by thread, or by 
individual emails. I strongly prefer the latter, because it's easier to 
delete stuff that strays off topic.


I have also filtered a few "from" addresses directly to trash because 
the emails are often argumentative, political, or otherwise unfriendly.


I've never done that -- my delete key works fine.

You get what you pay for. Yaesu has been making very dirty radios -- 
clicks and splatter have been the rule. Elecraft rigs have always been 
very clean on CW, less so on SSB, but nothing like Yaesu on SSB.

True, but LiFePo4 are widely available, and more tolerant of careless

I use 4S2P Lithium Ion. Like:

Since it has 16.8V peak, I charge it via a diode for 16V. A diode internal

Are you saying that have you installed this battery pack in place of the

Are you saying that you're using the KXBC3 to charge your lithium pack?

Do you charge this battery in the field with either a solar panel or the

This is 12% over 13.8 V. Lasts a long time. Full power up to 15W. No problem

The KX3 is my favorite of my HF radios right now. But one of my annoyances
is the internal battery limitations.

I always wind up carrying an external 6_Ah or 10_Ah LiFePo4 battery into the
field when I use this radio, an external charge controller, and solar panel.
It's not a big problem, but it also should not be a big project to improve
this situation. The KXBC3 has enough real estate to include a lithium
battery charger, and even a solar charge controller in its space. The amount
of battery energy that could fit in-place of the NiMH cells could
approximately triple the capacity of the AA cells.

So I have these questions:

1) How many of you out there might buy an upgrade which replaces the
KXBC3 board with a lithium battery manager, and a associated battery pack?

2) Are there any 3rd parties already making anything like this?

Re: [Elecraft] K4 Power Supply Recommendation

[John Shingara]

Thanks everyone for the replies and advice; much appreciated.  This is exactly 
the kind of question I would bring to my SK father so it was very nice to read 
the advice posted as if it were coming from dad.  It was all practical 
interesting. It made me miss having these discussions in his shack while he was 
building some project.  

I have since ordered an Astron RS-70M-AP.   It’s a big old (48 lb) linear and 
more than I will probably ever need.  The 70 was only $10 more than the 50 on 
HRO and it has a cooling fan where the 50 does not so I thought it may be more 
robust.   I plan to run all of my HF from this amp (KX3, KX2, and hopefully 
soon a K4).  I’ll use the PowerWerx SS30DV switcher for my Yaesu FTM-400DR VHF 
and UHF in he shack.  

Thanks again everyone!

Re: [Elecraft] WSPR (OT)

[Drew AF2Z]

Check the Activity section of the WSPRnet.org site: you can see which 
slots stations are occupied. Also, check the received signals on your 
display and select a vacant spot.


But it doesn't matter very much-- wspr station transmissions occur at 
random intervals so that stations on the same frequency will not 
consistently interfere with each other. This assumes everyone has 
selected a reasonable Tx Fraction, not 100%.

[Elecraft] Saving/Sharing Macros

[Andy Durbin]

"I would like to share my K3s macros with my son. In the K3 utility I click on 
the save button, but cannot find the file. Are they stored in a file I can copy 
and send to him or do I have to make a screen shot or copy and paste to a text 
file.?"

I don't have a K3 but Elecraft stores KAT 500 and KPA 500 config files at:

(local disk name - typically C:) / Users / (your user name ) / Appdata / 
Roaming / Elecraft

I expect you will find a K3 folder there.
