Re: [Elecraft] K4 & KPOD

[hawley, charles j jr]

I've used two KPods connected to the K4 at the same time. The buttons are the 
same of course but the knobs can be VFO A and VFOB which is kind of handy at 
times.

[Elecraft] k pod repair

Here is a reply I received from Elecraft when I needed a switch. They did send 
me a couple as well.

"Thanks for contacting Elecraft. Apologies for the slow turn time.
The eight switches in a KPOD in question are Elecraft P/N E640062, described as 
" SWITCH,TACT,12mm,SMD".
Our distributor DigiKey calls them

[Elecraft] ELECRAFT HAT is now in stock...

[hawley, charles j jr]

I'm wondering if the newest hat has an adequate crown. I have three of them and 
the first one seems better than the second one. I gave that one to my wife and 
bought yet another. It's not so good either.
SO...I bought a Northern California DX Foundation hat which was suggested here 
and it's great. Half the price too, but that's not a deal breaker.
I still miss wearing the Elecraft hat...hoping that I'll meet someone at the 
coffee house who also has a K transceiver but is hatless and speaks out when 
they see mine.
Any reviews on the latest hat?

Re: [Elecraft] KAT500 drops out during voice peaks

No, it’s always been on manual since I got it. And it never used to do this. 
Nothing is changed in the shack except in using a 4:1 balun instead of a 1:1. 
The timing is similar.
Tomorrow I’ll reinstall that and see if it persists.
An arc outside is a thought too. I will check my open wire feed line as well.
Thanks for the replies.

[Elecraft] KAT500 drops out during voice peaks

I've been having my tuner go to high swr a random voice peak.
The utility shows the right settings after a drop out but the Amp Key Interrupt

And the swr showing on the LEDs is high.
Not sure what is going on.

[Elecraft] Elecraft Baseball Cap Not Great

[hawley, charles j jr]

I have gotten three of these. The first one fits and feels great…made in 
Bangladesh. 
The second one, too small…not enough crown and easily blows off my head in a 
mild breeze…made in China. 
The third one I bought hoping that the second one was an anomaly…but still 
shallow crown…made in China.
I really like the first hat, but my wife says I look homeless because it’s 
badly faded, etc.
I see that the hat now costs $5 more…kind of a lot to take another chance.
I gave the short crown hats to my wife.

[Elecraft] Plug on KPA-1500

[hawley, charles j jr]

I don't see a picture of your plug. Looking into the 6-20P  240 vac/ 20 amp 
plug with the ground pin up, it should have a vertical blade on the left and a 
horizontal blade on the right. Is that what your amp came with?

The 120 vac/20 amp plug, NEMA 5-20P,  has the blades reversed...horizontal 
blade on the left and vertical on the right. Is that what your plug is, or is 
the electrician just confused?

Re: [Elecraft] Dummy Load with integral digital wattmeter

[hawley, charles j jr]

I have one. I like it, but I was thinking more of a test unit.
Dummy load with integral digital meter (digits preferred instead of LEDs)..
To make one out of a W2 would require a W2, that after market KV5J digital 
readout or a computer, and the directional coupler. Lots of stuff and wires.
But maybe if I found a stand alone digital wattmeter I could fasten it to a 
dummy load...that's a thought.

[Elecraft] My THIRD Elecraft Hat

[hawley, charles j jr]

I just received my third Elecraft hat. It fits perfectly...just like my first 
Elecraft hat. When I got the second hat, it didn’t seem to fit properly. Kind 
of seemed short of coming all the way down on my head. I compared it to the 
first hat and it seemed the same, but just didn’t fit right. Didn’t come down 
all the way and feel secure.
This third hat is great.
So if you get a funny hat after you order another hat because of kinda wearing 
out your first hat...my wife was gonna burn my first faded and sweat lined 
hat...said I looked homeless in it...just keep ordering them until you get a 
good one.
I’m so psyched...I may just order a K4 now...a third rig...to set next to the 
K3es.

[Elecraft] K Pod switch replacement or fix?

[hawley, charles j jr]

I’ve been wondering as I contemplate replacing at least two of the push button 
switches, if there is a more permanent fix.
The schematic is available on the Elecraft website.
What do you think of installing say a 10K pull-up resistor from the 3 vdc buss 
to each of the switch outputs. I wonder if that would stabilize the inputs. It 
seems like the issue is no-current switching making the contact noisy after 
repeated use. 10 K doesn’t seem like much of a current to help, but that and 
maybe the presence of a load would reduce the noise to the pic processor.

[Elecraft] Keyboard plugged into the P3 SVGA works but...

[hawley, charles j jr]

I asked the question how do you type live and send CW, and got the answer about 
the Menu set to VOX.
That works now but it doesn't work in SSB to automatically offset and send out 
CW like with paddles plugged into the K3.
Is this not possible with the keyboard and SVGA?

[Elecraft] KEYBOARD Plugged into P3 SVGA...can't type out live.

[hawley, charles j jr]

I can type into the transmit buffer and with ctrl T, transmit the CW. But with 
the VOX turned on in the K3s, the typing doesn't go out as I type, but fills up 
the buffer. I still have to hit ctrl T to transmit.
Am I missing something that needs to be turned on or off?

[Elecraft] P3 Transmit Display Failure

[hawley, charles j jr]

I have a reoccurring issue with the P3 display of the transmit cw display. 
Occasionally, the P3 doesn't display the TX waveform ( I have never noticed if 
this happening on SSB...probably not since I have never had to fix it). The fix 
is loading a config file stored when the problem was not happening.
I have tried to store a config file when it was happening just to see and then 
restore using that file. What happens then is the P3 display locked up with a 
dit and could not be unlocked.
After this test, I had to turn off the K3s and unpower the P3, restore power 
and turn the K3s on, and restore with a copy of the config which was taken when 
the display was showing transmit cw.
I'm thinking stray RF somehow causing this but never happened on SSB...and I 
have no clue what is getting flipped in the rig or P3 to have this happen.
Since I can restore the config and fix it, I guess I'm mostly curious why it's 
happening, any ideas?

Re: [Elecraft] K-POD Button Switches Intermittently triggering the wrong macro

[hawley, charles j jr]

The switches are surface mount and quite sealed. The surface mount on them is 
not a problem the way they are soldered in. But ultimately, it seems like 
Elecraft needs to replace them as to brand, model, in their production if they 
haven’t already done so. 
When I called for replacing pod number 2, I was told that this was extremely 
rare and even not likely for someone to have two of them go this way. But with 
a little persistence they sent me my third one. I think they are getting old in 
the tooth now, so we should see more “rare” failures ahead. As of right now, 
replacing the pc board for $120 is probably the way to go, with the hope that 
the switches are a more reliable sort.
I, so far, went the way of just switching my most used macros to relatively 
unused switches. Good for another almost year I hope.

[Elecraft] K-POD Button Switches Intermittently triggering the wrong macro

[hawley, charles j jr]

I posted this on Elecraft .io but will try here as well...

I love this K-Pod, BUT I’ve sort of worn out 3 of them. The symptom is that the 
most used buttons get noisy and trigger another macro from another address. 
When I had the first one do that, I did extensive testing to eliminate rf 
noise, etc.
And a new unit however proved to work perfectly...for about 4 months. When it 
started doing the same thing Elecraft said it was highly unlikely and 
especially twice to the same guy, but they sent me another one anyway. Great 
company!
Now that one after a year is doing it again. I rearranged the macros to 
different buttons of the two macros I mostly use, and it works flawlessly again 
for me. I doubt that Elecraft will keep sending me these things, but maybe I’m 
missing something. But all I can come up with is noisy switches, double 
triggering. No switch bounce protection?
I notice now on the Elecraft site that there are PC boards available for about 
$120. Almost doable if the switches are not available separately, and less 
expensive than the $290 for a new unit.
Has anyone come up with a part # for the original switches?

Re: [Elecraft] Newer Elecraft hat not as good as the earlier ones...

[hawley, charles j jr]

Well the newer had just doesn't sit on my head as well as the older one. In a 
light wind, it tends to take off. I adjusted the band in the back, etc. and the 
only thing I can come up with is the hat is not as preformed as the old had 
was. So I thought it must be that the material is thinner or something. Even 
though they are the same brand and look identical inside, they are made in 
different countries. So they are different.

[Elecraft] Newer Elecraft hat not as good as the earlier ones...

[hawley, charles j jr]

I really liked the Elecraft hat (baseball cap) I bought a couple years ago so I 
bought another one this year just to have a spare. BUT the newest one, while 
the same brand, is not the same. They are made in different countries. The 
cloth is very limp and does not feel as secure and comfortable as the old one. 
They look the same inside and outside, but don’t feel the same and it seems to 
be the material difference...too soft and limp.
Silly issue I know, but while I am pleased about and have just about everything 
that Elecraft markets, I’m disappointed by the latest version of the hat.

Despite what hat website says, there are no kits available.  Tom Hammond

All the instructions are there, and I believe Tom used FAR Circuits for

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]”

I’m from Chicago, so seems like we got three or four at once. But I do remember 
the first TV set, Dumont 12 inch round tube, 1948.
A friend of mine got a Halicrafters 5 inch or so near the same time, and an 
antenna on a tower. Plus an oil filled thing to look through that made the 
image bigger.
Remember those colored plastic things people put over the screen to add a bit

Re: [Elecraft] K-POD Issues, But I Love It!

[hawley, charles j jr]

Another small issue I have had is when I am on say 3710 KHz LSB
and send the macro FA705;MD3;
the K3s goes to 7049.280 KHz CW sometimes. (720 Hz is my offset for CW)
If I send FA705;MD3; again right away
it goes to 7050 KHz CW

Then when I send FA371;MD1;
the K3s goes to 3710.720 KHz LSB sometimes
Again, if I send FA371;MD1; again right away
the K3s goes to 3710 KHz LSB.

This has always been the case and has nothing to do with the wrong macro being 
sent...
am I not allowing for something in my macros?

I love this K-Pod, BUT I’ve sort of worn out 3 of them. The symptom is that the 
most used buttons get noisy and trigger another macro from another address. 
When I had the first one do that, I did extensive testing to eliminate rf 
noise, etc.
And a new unit however proved to work perfectly...for about 4 months. When it 
started doing the same thing Elecraft said it was highly unlikely and 
especially twice to the same guy, but they sent me another one anyway. Great 
company!
Now that one after a year is doing it again. I rearranged the macros to 
different buttons of the two macros I mostly use, and it works flawlessly again 
for those two. I doubt that Elecraft will keep sending me these things, maybe 
I’m missing something. But all I can come up with is noisy switches, double 
triggering. Anybody have similar issues?

(I seem to have somehow misplaced mine.) The jack itself seemed to measure

Wasn't there a debate between Maxwell and Walter Bruene (designed the Collins

Re: [Elecraft] Waterproof SO-239 covers

[hawley, charles j jr]

I wiggle the connector as I finger tighten the barrel. The result is that they 
are difficult to unscrew. Also I use a heavy silicone grease on the threads and 
on the back where the barrel contacts the connector. I have never had any 
issues with water in 20 years doing that.

Re: [Elecraft] KX3 power out

[hawley, charles j jr]

I believe the calibration is under the label on top of the slug. I would guess 
if you had knowledge of a source of RF that would deflect the meter accurately 
mid scale given the slug you were calibrating, then that would be the best you 
could do. 

Not it matters for most ham radio use...fairly accurate repeatability is 
probably a much more valuable test result.

Re: [Elecraft] Wayne's Story - "On Second Thought, I'll Take The Stairs

[hawley, charles j jr]

I've been riding a motorcycle for 50 years...now I know why. 
I did read Pirsig's book when it was first published, but didn't remember this. 
I did remember that his friend rode a BMW and Pirsig made shims for the BMW's 
handlebar mounts out of a beer can, but was careful to never tell his friend, 
John I think, where the shims came from.

Re: [Elecraft] K4 under the hood

[hawley, charles j jr]

Elecraft is one of the most hands on companies. Just super when you talk to an 
engineer and get advice on how to self diagnose.
Back in another life I had an HP 60 KHz antenna preamp fail. Talking to an HP 
engineer, he suggested that he had one of those in his desk drawer and would 
pop it in the mail. That’s what I look for with ham radio purchases.

Re: [Elecraft] KX2 power cable polarity?

[hawley, charles j jr]

All good info about different rigs having reverse polarities on the connector. 
But this is about the cable for the KX2. 
BTW, if you read page 5 of the KX2 manual, under power supply, the manual 
states that the center pin is + and the striped wire is +. Checking the cable 
with an ohmmeter is highly recommended...never know when the wire supplier 
changed something. However I would assume Elecraft would not redesign the 
socket polarity. So that's reasonably safe.

It was the first iteration of the XG2. It was only one band as opposed
to 3 on the XG2. It went out of production after the XG2 release.

I only know because I was asked to produce an enclosure for an XG1 and

Re: [Elecraft] K3s discontinued?

[hawley, charles j jr]

I wondered too, since the K4 was almost a bargain with it's features over the 
K3 with options price wise.

I watched the video...ELECRAFT K4 IN DEPTH with WA6HHQ at Waters & Stanton Ltd 
Portsmouth UK

https://www.youtube.com/watch?v=r-PHL68WIdg

and got anxious to get one when they quit hogging them for themselves. :)

If you "load-up" a K3S with all the options you'd have to buy that are

I think you'll find the K4 is a BARGAIN!

Hi Gary,

We sold the last K3S, I believe, but we'll have a number of upgraded, fully
warranted K3's available for purchase on the web site sometime soon. Some
were used for DXpeditions.


Was there a reason why the K3s was discontinued?

Yes; we felt it was time to create a new, hybrid SDR with a large,
integrated touch screen and virtually unlimited hardware/software expansion
capability.

The K3/K3S had a good run -- over 12 years. During that time we created many
options and accessories and released dozens of free firmware upgrades.
Everything we learned from that experience, plus a lot of new R, is being
incorporated into the K4. (It's an exciting radio. For me, every morning
it's a battle of wills to stop playing with it and get my work done :)

We're looking forward to getting the K4 into customers' hands. Our suppliers
are coming back on line. And so are we ... but we're prioritizing the health
of our staff, which requires some heroics from the facilities department.

Re: [Elecraft] stripping insulation from enamel wires

[hawley, charles j jr]

I use a Knipex wire stripping tweezers

https://www.amazon.com/Knipex-1511120-Coated-Wire-Stripping-Tweezers/dp/B003RWS8XE

I ordered the 0.5 blade which seems to be best for our small wire.
Use a light pressure and this thing works great.

Subject: [Elecraft] stripping insulation from enamel wires

Here's an old problem that I've never solved: how to strip the enamel
insulation from wires for winding toroids.

The instruction say:
-dip in a solder pot which I don't have
-use a soldering iron to, presumably, burn the insulation off which
has
never worked for me.

Leaving soldering pots aside, the hot iron approach has never burned
off
any insulation even with tip temp's hovering around 1000F. Just
doesn't
happen. Maybe it's the soldering iron, maybe my method, but
whichever,
the enamel insulation just sits there. I end up using a file to
scrape
off the insulation which is tough on the wires and hard to predict
when
enough is enough. Any insightful hints? Thanks much.

Re: [Elecraft] MH4 Mic on a K2?

Ah so...
That's going to take some disassembly. Disconnect the battery. Remove the RTC 
and unscrew the control board and pull the front panel off I guess. I just 
looked and need to install the 5 volt jumper and then the resistor. I finished 
building this 10 years ago so I had to get out the assembly manual 

Hi Charles,

Bias for the MH4 (and previous MH2) mic is provided by placing a 5.6k resistor 
between pin 1 and 6 on the mic connector of the K2.

Most of us just solder the resistor to those pins on the back of the mic 
connector on the Front Panel Board. My MH4 came with a small envelope that 
contained a 5.6k resistor and 8 2-pin jumpers for the mic config header. The UP 
and DN buttons on the MH4 switch between  VFO A and VFO B on the K2. It 
switches bands on the K3, KX3 and KX2.

Re: [Elecraft] KPA500 Dead

There’re a couple things in series with the transformer primaries that look 
like thermistors. Wonder about them. They’re labeled T and SL 1, and SL 2.

Re: [Elecraft] KPA1500 power per frequency bin

[hawley, charles j jr]

So...is it possible that the KPA500 could ever be upgraded or be a KPA500A to 
be as capable as the KPA1500?
I am not comfortable with having a 1500 watt amplifier and probably would have 
to suffer all that noise and bother just to run a couple or few hundred watts. 
That is what I love about the KPA500, compact and super quiet.

Re: [Elecraft] FIXED--was NOT the feedline

[hawley, charles j jr]

I have used a very thick non migrating silicone vacuum grease on the UHF 
connectors in the past to waterproof them. I put some on the threads and on the 
rear of the center section that the barrel pushes against. They have been up at 
40 feet in all kinds of weather for 30 years with no problems. I considered 
tape, etc. but it seemed that if some water got in, it would have difficulty 
getting out. Better to not provide a container for water.

"The most likely contact scenario would seem to be that the shell of the USB 
connector made contact with a grounded nut on the power supply. "

I received an email that said Astron power supplies have exposed transistors 
that are not at ground potential.  That prompted me to investigate the Astron 
design.  Page 13 of this paper http://www.wb1gof.org/files/AstronPDF.pdf  shows 
the bottom of the case has an exposed stud/nut with 13.8 VDC.

It may be interesting to find out (by analysis) what the PSU does if this stud 
is grounded.  If the output voltage goes high it could explain the KXPA100 and 
KX3 failures.  Maybe someone already knows the answer.

Re: [Elecraft] Availability

[hawley, charles j jr]

I think I would get the KX3 which is in stock and maybe the KPA500 and KAT500. 
I’m not a 1500 watt guy. The KX3 can drive that to 250 watts or so...and get 
the K4 later.
The KX3 would be a fun radio to keep.

Re: [Elecraft] Voltage drop in power cable

[hawley, charles j jr]

I wonder what the time constant is for that sense to respond...say to CW or SSB

Re: [Elecraft] K3S poor CW keying further investigation

[hawley, charles j jr]

I did notice that the post mentioned that his power supply dipped in voltage 
but as for preventing issues due to low voltage, it's not your voltmeter on the 
power supply that is the proper indicator. It is the voltage on the input to 
the K3 that you should be noting. It's available on the menu and displays in 
the VFO B area on the screen.

Re: [Elecraft] K3 - NOT K3S - issue: TX Calibration fails on 6m only

[hawley, charles j jr]

Thanks for the information. I did not have a tuner in this K3S when it failed 
the 6M cal so I figured it was just marginal for some reason since it DID pass 
on the third try. I have read the Config menu now and see how to check the gain 
and do a manual cal if necessary.

I was just afraid to do the Cal again with the utility since it did eventually 
pass. I thought...leave it alone. But I did want to investigate the 6M gain 
etc. and understand what it was all about. I see now that I can do a manual Cal 
on 6M only if it becomes necessary. I need to learn to read the pages on menus 
in the manual as well as the index. I checked as you suggested and my gains are 
LP 10 watts and HP 34 at 50.135 MHz. Also I did as you suggested and the dummy 
load tune SWR is 1/1.1
So all good I guess.

Thank you again,

Could be a burned trap on the KAT3 (most likely). Just jumper the coil,
L10 and it will bypass a burned capacitor. The trap was found to be
redundant.
Make sure 6m is on the correct antenna not 2.
In TUNE, does it really have High SWR?
Set ATU to BYP for any tests using dummy load.

Make sure TECH MD is on, then look at config menu TXGN HP (or LP below
12w [8w 6m]) for the gain number.
Try a manual TX gain cal on different parts of the band, every half a
meg or so and see if it will pass.
(set TUN PWR to nor, set power for 50w EXACTLY, then long press XMIT to
send a carrier at 50 w for several seconds)
Then check the TXGN number.
You can do it at 5.0 watts exactly for the LP gain cal.

Re: [Elecraft] K3 - NOT K3S - issue: TX Calibration fails on 6m only

Other than using a computer, is there a menu item where the tx calibration 
values can be seen?

Tha manuals are pretty much assuming that you have a computer and still have 
the one that you did the calibration on.

Re: [Elecraft] K3 - NOT K3S - issue: TX Calibration fails on 6m only

I had the same issue with a brand new K3S. It failed a couple times and then it 
passed once...so I left it there. I have not been on 6M but I assume it will 
work fine. I do feel apprehensive though about running the cal again.

Subject: [Elecraft] K3 - NOT K3S - issue: TX Calibration fails on 6m only

I am helping a friend upgrade an older K3/100 (s/n 798) after he recently
acquired it from estate of a SK.  I have brought firmware forward one or two
versions and installed the KIO3B board set.  The radio has main RX only and
the KSYN3A upgrade.  It does have the KANT3 antenna tuner.



I ran the 5 watt TX Calibration and it failed due to high swr on 6m only.  I
thought this curious so ran this test against one of my K3S with the same
high quality dummy load and cable.  It passed.  I also scanned the dummy
load with my RigExpert and it is flat to at least 2m.



We would appreciate any suggestions as to how to further troubleshoot this
issue.  My friend says that 6m is not important to him - today - but
tomorrow might be a different story.  It seems reasonable to us that so long
as we are working on it, we should leave it fully operational.



I have not looked to see if the front panel to main board pin upgrade or any
other hardware mod has been performed.

Re: [Elecraft] Extra Protection For KPA500? AUX CABLE SET??

[hawley, charles j jr]

Not getting any answers from Elecraft.com...still thinking about getting new 
cables that aren't as thick as a garden hose!

KPAK3AUXSE Enhanced Mode. Aux Cable Set + second E850463 Aux Cable
Enhanced Mode. Aux Cable set for KPA500 AND second E850463 aux cable for 
KAT500. AUX Cable Set incl: 15-Pin to 15-Pin DE-15 + Key Line Interrupter 
adapter

So does the Aux Cable Set include two E850463 cables for $50 or only one 
E850463 and the key line interrupter?

And to get two E850463 cables, you have to order two E850463 cables at $30 each?

One other thing to consider is that you don’t want to connect all of the pins 
straight through from the K3 to the KPA500. There are some conflicts that will 
cause problems. The Elecraft cables are set up properly with the appropriate 
pins cut that should not connect between the two devices. An alternative is to 
use a straight-through HD15-HD15 cable with the appropriate pins cut. Cutting 
them yourself is a pain, so we really don’t recommend that route.

 George:

 I must be missing something because when I select PER BAND in the config 
 menu, there's no power setting to set.

 It doesn't display the power like TUN PWR does where the tune power is 
 shown within that menu item so you can adjust it.

 I have to order the AUX cable, but in the meantime I'd like to use this 
 setting with the K3S so any suggestions would be appreciated.

[Elecraft] K3S Transmit on LSB causes popup on USB

[hawley, charles j jr]

Several of us K3S users have noticed a brief intermittent popup on USB when on 
80M LSB. It seems to have something to do with transmit ALC settings, but can't 
get rid of it.
It also happens most with higher in frequency voice syllables.
One operator switched from his KS3 to a 7300 and the USB was clean.
Any ideas?

Re: [Elecraft] RFI issues

[hawley, charles j jr]

This is the newest one that brews a carafe of 10 cups or does a pod into your 
mug. I too have had others without any noise, but this new one puts a huge sine 
wave of noise on the panadapter. I have put ferrite on the line cord which 
don't affect it. I just turn the thing off after brewing...or wait about 5 
minutes and the noise goes away.

Hard to be disappointed when a delay beyond what was only a potential launch
date was inevitable. it’s a very complex transceiver, and manufacturing what
begins as a prototype is always difficult at best.

I have a Fluke 87...for a couple of decades now. It does it all well.

Re: [Elecraft] K3 - Power cable voltage drop

[hawley, charles j jr]

convenient. But the voltage drop was concerning. I go direct now to the rig.
