No discussions take place about Elecraft rigs that I own like KX3  KH1 
or friend's KX2.
Sure seems that the big rigs have a lot of problems - so it has been 
educational.

Re: [Elecraft] KX3 Spur/Birdie on CW Receive

[James Bennett via Elecraft]

OK - mystery solved! I had posted this on the Elecraft reflector and shortly 
thereafter realized it should have gone on the KX groups.io <http://groups.io/> 
list. So, I put it there and THAT is where my answer came from. Now, why it 
took almost a week to get into the Elecraft reflector is another question. But 
anyway, my problem was fixed AND now I know why I’m seeing double! Sorry for 
all the confusion, folks.

BTW - the “birdie” thingy was resolved by the Tech Mode entry RX ISO - turning 
it ON got rid of the “birdie”. Thanks to JPE1HZG for clueing me in to that one.

Re: [Elecraft] KX3 Spur/Birdie on CW Receive

[James Bennett via Elecraft]

Wow - this is strange! I posted this last week and got an answer fairly quickly 
- it was a setting in the tech mode menu that resolved it. Thought it was all 
done. Then this morning around 08:30 local time I got a couple messages that my 
post had been accepted from the reflector, and it all started over again!

Anyway, the “problem” is resolved on my end and now it looks like something 
funky is going on with the reflector.

[Elecraft] KX3 Spur/Birdie on CW Receive

[James Bennett via Elecraft]

Folks - 

I’ve got my KX3 connected via an MFJ 178B-SDR switch to my computer running 
SDR++. This gives me a nice BIG pan adapter display on my monitor. Additional 
software syncs the KX3 with SDR++ and RumLogNG - a logging program. Anyway, 
When I have the KX3 in CW mode, I see a birdie or spur (not sure the actual 
name for it) about 500 Hz up from my zero-beat frequency. As I turn the KX3 
dial, the spur mores right along with me. It is showing with a signal strength 
of about -79 db. Now I know that is a really low signal, but it does show up on 
the display and is a tad annoying. Actually, as I type this I’m on 10.116 and 
as I was testing, I find that there was a low level signal there, under the 
birdie. The fact it was being covered up bugs me a bit, too.

No matter what band I go to, my little “buddy” is there with me. If I switch to 
USB or LSB, it is gone - it only shows up in CW. And if I do CW-R, it switches 
to about 500 Hz below my frequency.

Anyone else have this? Is it something worth reporting to Elecraft, or is it a 
known “thing”.

72, Jim / K7TXA

[Elecraft] K3/100 TX problem on 20m

[James Holohan]

Hi. I had this problem in the recent past. It turned out to be an issue with my 
multiband yagi. It only occurred on 20m.
Hope this helps.

[Elecraft] KH1 display while transmitting

[James]

Four month wait for KH1, but it looks nice.  Six hours at 14 v to charge 
batteries. During transmitting, Power and SWR are displayed with values 
blanked.  How does one unblank so as to see values? Thanks

[Elecraft] FS: OT: Two Balun Designs Unun Units

[James Bennett via Elecraft]

Still cleaning out stuff from the shack that has had little use and needs to go.

I have two Balun Designs Unun units for sale.

First is their model 9135sw, which is a 5kW 9:1 (450 to 50 ohms) unit. It has 
side posts and a bottom SO-239 coax connector. It has been used for perhaps 10 
minutes. It works perfectly, just not with my current wire antenna 
installation. Due to physical property restraints (and HOA crap) I can’t really 
adjust my wire antenna to get an acceptable SWR. A new 9135sw costs $95 plus 
shipping. I can let this one go for $85, free shipping.

Second is their model 64131e. This is a 1kW 64:1 / 49:1 balun, designed for End 
Fed Halfwave Antennas. The side post on the left is for the 61:1 connection, 
two on the right - a 49:1 post and optional counterpoise post. Same situation 
as with the 9:1 model above. Very, very little use - just doing some SWR 
testing and was unsuccessful. A new one of these costs $116 plus shipping. My 
price for this one is only $95, free shipping.

Neither Unun has been opened up. Both are in factory new condition. The ONLY 
amount of RF sent into them was a few milliwatts via a Rig Experts AA-55 Zoom 
SWR tool. Needless to say, building my wire antenna has been an expensive 
experiment. FWIW - I ended up building my own Unun, a 36:1 unit that’ll only 
handle a max of about 100 watts. Works well, but not what my ultimate goal was. 
Oh well….

Anyway, if you are interested in either or both of these Unun units, please 
reply off-list. I accept PayPal family & friends, cash or personal check.

Thanks & 73, Jim / K7TXA

Re: [Elecraft] Misc QRP Stuff

[James Bennett via Elecraft]

As of 09:22 this morning (Mountain Time) only the QRP Guys Antenna Tuner and 
two of the KXUSB cables are left.

If anyone is interested in some non-Elecraft QRP rigs (QDX and QCX Mini), I’ll 
be posting four of them over on the QRPLabs Groups.io <http://groups.io/> site 
later today. Or, contact me me direct via email if you want info and/or to 
avoid the rush over there. :-)

[Elecraft] FS: KPA500 / KAT500 Combo

[James Bennett via Elecraft]

Time to clean house of items that are rarely used. I’m selling my KPA500 
(serial # 3645) and KAT500 (serial #2726). Both were built by me a few years 
ago and work perfectly. I started out using them with a K3, then a K4D, and 
most recently a Kenwood TS-890. Both the tuner and the amp work perfectly. 
Neither has any scratches, dings, or dents and have been used in 100 percent 
non-smoking environments. The amp is set for 117 volt operation and includes 
the correct power cable.

Included will be the following manuals: KPA500 Kit Assembly Instructions, 
KPA500 Owner’s Manual, KAT500 Owner’s Manual, and the Fred Cady (KE7X, SK) book 
on the KPA500 and KAT500, 2nd edition.

In addition you’ll get the interconnecting cables. I currently have the pair 
connecting my TS-890. You’ll get the corresponding cable(s) for that 
arrangement along with the cables to connect to a K3 or K4 if that’s what you 
have.

The amp and tuner have been in use here at my Idaho QTH for 2-1/2 years, 
connected to a Zerofive Flagpole Vertical. With 110 feet of RG213, the tuner 
has been able to get a match on 160 - 6 meters, no small feat indeed! Sadly, I 
simply don’t use the amp and tuner all that often, I need the dollars, so 
they’ve gotta go.

The KPA500 will be shipped in an Elecraft factory double boxed carton. I’ll 
have UPS professionally package up the KAT500.

I much prefer to sell the amp and tuner as one package, price: $2,900, FREE 
SHIPPING, NO SALES TAX. Check the price for a brand new pair and add tax - my 
price will save you some serious dollars!

I prefer PayPal friends and family, but will accept cash or personal check (10 
days to clear a check, sorry).

Re: [Elecraft] KPA500 Fan Question

[James Bennett via Elecraft]

Yes, but the amp is not seeing the mis-match, correct? The tuner is taking care 
of that mis-match and I would have thought that the amp should be perfectly 
happy… Yes?

[Elecraft] KPA500 Fan Question

[James Bennett via Elecraft]

Got a question (problem?) regarding the fan in my KPA500. I'm driving the amp 
at 29 watts from a Kenwood TS-890S. The amp is connected to a KAT500, which in 
turn is hooked to a 30 foot tall Zerofive flagpole vertical. The tuner has 
provided me with a nice 1.2:1 SWR, as displayed on the amp. The resting temp of 
the amp shows 42C. At 29 watts input to the amp, I’m seeing about 480 watts of 
power from the amp. The amp has nothing sitting on top of it, and the wall 
behind it is over 12” away. There is about 2” clearance on either side of the 
amp, and it is sitting on top of the KAT500.

The issue: The fan comes on in a very short time - less than 20 seconds - and 
the temp display runs up to 50+ degrees. If I start calling CQ or get into a 
QSO, it doesn’t take long for the temp to show over 60 degrees and the fan is 
running at max.

When I had a K3 and more recently, a K4D - this did NOT happen. The fan would 
come on but NEVER at the max, loud level. Interestingly, many moons ago I also 
had a KX3 and had it connected to the KPA500. I noticed that the fan would also 
come on fairly quickly with that rig driving the amp, but I never thought too 
much about it. Until now...

But now, I think there is some sort of problem. It seems to me that the temp 
shouldn’t get that high that fast nor should the fan start roaring in that 
short amount of time. I could understand it if the SWR was really bad, but at 
1.2:1

Any ideas why the amp fan should be acting this way with a non-K3 or non-K4 
driving it?

Re: [Elecraft] [Elecraft-K4] K4D with KAT4 Tuner

[James Bennett via Elecraft]

OK - surprised, I am - not one single offer for my K4D that I posted on 
Tuesday. So, I suppose I need to lower my expectations (and price). 

The K4D with internal KAT4 tuner is now for sale for $5,500, no tax, free 
shipping to any USA address.

[Elecraft] FS: K4D with KAT4 Tuner

[James Bennett via Elecraft]

Folks,

After a lot of “should I / shouldn’t I” discussions with myself I’ve come to 
the conclusion that I probably should let go of my K4D, serial number 636. It 
has the KAT4 internal auto-tuner in it. It was put into service in April of 
2022 and has been here at my home, in a non-smoking environment ever since. It 
works perfectly, has no scratches or dents. The majority of its use has been on 
CW, with perhaps ten percent of my QSOs being FT8. I’ve had it connected to a 
KPA500/KAT500 since installation last year.

A brand new K4D with KAT4 will run you $6,480 plus any applicable sales tax. In 
the state of Idaho (6 percent rate) that would come out to another $388, so 
buying a new one here would set you back $6,868. Plus…. You’ll have to wait for 
shipment - not sure what the current backlog is at Elecraft.

I’ll sell this one for an even $6,100, NO TAX, FREE SHIPPING (in the original 
Elecraft cartons) the day after payment made to any USA address. I prefer 
Paypal Friends and Relatives but would also accept a cashier’s check. Please 
let me know if you are interested. :-)

Also posting this on the K4 Groups.io  site.

[Elecraft] K3S dead.

[James Holohan]

My K3S (Serial No. 11048) is completely dead and pressing the power button has 
no effect.  FS1 and FS2 checked out OK. Removed KP3A to eliminate that as a 
possible cause. Measured 13V on pins 1,2 & 3 of Q2 but nothing on pins 5 to 8. 
Appreciate any guidance on this fault.

Re: [Elecraft] TL-922

[James F. Boehner, MD via Elecraft]

Josep,

Be sure to install a soft-key interface in the TL-922 before hooking it up to 
the K3.

https://harbachelectronics.com/shop/kenwood-tl-922/sk-922-soft-key-keying-interface/
 

The newer rigs were not meant to handle the voltages on the older amplifier's 
keying circuits.

I modified mine with the soft-key board and added the new capacitor block.

Hi guys,

Have a couple of Kenwood TL-922’s around and was thinking to connect one to a 
K3.
Has anybody done so.? And if so, how have you done the wiring.? 
Got 2 K3’s (in fact I have 3 of ‘em, but one not physically at now now) and 
maybe one day I can use the spare one with a TL-922 from another QTH.

Thanks,

Re: [Elecraft] Tripod for ATX1 Tripod Adapter

Bill,

I had a similar problem but solved it by carving out part of the side of the 
tripod platform to accommodate the bnc connector extending downward.  The

It is the Amazon Basics 50-inch Lightweight Camera Mount Tripod Stand With Bag

The problem is that the AXT1 Adapter will not screw on because the BNC

3 or more feet.

Any suggestions?

Re: [Elecraft] Running high power

[James F. Boehner, MD via Elecraft]

Al,

I saw your question and saved it, as I knew you would be getting much better 
responses than I can give.  I have five amplifiers, as I tend to like building 
stations.

You received the responses I expected.  Grounding and bonding are indeed 
important and great information is found on K9YC's page as well as the ARRL 
publication "Grounding and Bonding for the Radio Amateur".  Yes, mix 31 
ferrites are your friend.  There are many sources; I bought mine from Pro 
Audio.  Sadly, many consumer devices are very poorly designed for RF 
environments.  Some problems can be mitigated, some not.

I do not know if anyone has talked about using a well-tuned antenna system, 
keeping SWR low and RF out of the shack.  

I am fortunate that the only interference to devices in my home occur on 160, 
but I'm sure most of that is because I'm using an antenna similar to a G5RV fed 
with 450 ohm twin lead, I short the twin lead and then use an UNUN and antenna 
tuner to achieve resonance. (?Marconi "T"?)  I do have a counterpoise.

I know many do not talk about amplifiers as they are shamed for using high 
power.  Whatever.  I saw someone at the 2019 Dayton Hamvention with a shirt 
that said "1500 watts - 1 watt = QRP!"  No shame there.

The one thing I do know, the problems that you can get from a high-power home 
installation do not even come close to running high power mobile.  That WAS a 
nightmare.

The one universal thing about amplifiers is that when the doorbell rings, the 
amp gets turned off!

Good luck-this is an interesting journey!

Subject: Re: [Elecraft] Running high power

Thank you for all your responses. I did not mean my question to solicit the 
thousands of ways of solving this problem, but merely a poll of hams' 
experiences running high power. Based on all of the private and public 
responses I received, it's about 50% who've had problems with consumer 
equipment and high power.

If the problems are caused by simple RF overload of the piece of equipment, 
I've never understood why balanced or unbalanced antenna systems make any 
difference. If your 1500 W signal induces a large interferer on the circuitry 
of your internet modem or garage door opener, the device has no idea whether 
you're using a Yagi or a dipole or a vertical or whatever. It's just being 
overloaded because it's in the near field of the antenna and has very poor 
rejection and filtering. You could have the best-balanced antenna system in the 
world and still get into a poorly-shielded modem, couldn't you? The 
interference isn't coming in through the wires, it's coming in through the air!

I tend to resonate with K9YC's assertion that there are a whole lot of devices 
out there that are designed badly, susceptible to the slightest overload. When 
I look at my own situation I notice that I have tons of devices that were 
completely unaffected. My telephones, lights, garage doors, overhead fans, 
smart thermostat, and many others-- all of which have RF circuitry to one 
degree or another-- were never bothered.

Taking the FM radio in the kitchen as an example, you could make the argument 
that since its whole purpose in life is to receive weak signals, that it's 
particularly vulnerable to a large HF signal. But not a single person mentioned 
that they've ever heard themselves coming through their FM radio. I must have 
the only cheap table radio in America!

Anyway, I envy those of you who told me, "I haven't the slightest idea what 
you're talking about." 

R,

Al  W6LX

Re: [Elecraft] Running high power

[James Bennett via Elecraft]

Al - I’m not on the RFI reflector, but wanted to give you a quick reply here, 
since it in a way does involve Elecraft things. I have a K4D, KPA500, KAT500 
and run RG-213 to a 30 foot tall Zerofive Flagpole vertical in the back yard - 
10 various length radials. I put isolation transformers on each end of the coax 
run. The main RFI issue I had with this setup, running 500 watts, was that I’d 
turn on the overhead lights in our two garage door openers. A couple mix 31 
ferrite clamp-ons at the opener motor box took care of that problem. Every 
situation is different. If you’ve got your equipment properly bonded together 
and grounded, then attack each device with ferrites. It’s a PITA, but not 
insurmountable.

Like Pete mentioned - there probably will be some RFI to deal with one way or 
the other. It’ll come from common mode current on your feed line or simply 
having some household device swamped by RF that it isn’t designed to handle. 
Trust the mix 31 ferrites - they are your friend! 

BTW - didn’t have that issue running my K4 at 100 watts - only when I got above 
about 350 did those lights turn on. :-(

[Elecraft] Design flaw in K3s

[James Michener]

It isn't a matter of if your K3s will fail, it is a question of when.   
The radio's current sense resistor (SMD 1206) is rated at 1/2 watt,  
while (depending on options) will dissipate nearly 2 watts at 10 watt 
transmit.  It took several years but my resistor drifted from 0.05 ohms 
up to 0.068 ohms triggering HI CUR errors whenever I turned on the sub 
receiver.  I am glad it didn't unsolder itself.   I did this write up on 
the web.


http://k9jm.com/K3sCurrent/ElecraftHiCur.html

Note:  The original K3 has a higher wattage current sense resistor and 
should be fine they cheapen the K3s

Re: [Elecraft] [K3] K3 MacOS M1 Mini

[James Bennett via Elecraft]

David,

I used a K3 up until about three months ago on my Mac Mini (intel-powered) with 
no problems at all. The K3 was sold and now the Mini is connected to a K4D, 
which also plays well on the platform. My Mini has 32GB on non-Apple Ram and 
the hard drive (SSD) is 1TB. OS is Monterey 12.5.1

Like another poster, I used MacLoggerDX (MLDX) for all of my logging and 
SkookumLogger for contesting - a great combination. Don at Dog Park Software 
has been super quick answering any questions I have on MLDX, in addition to 
providing quick fixes for some minor issues. Also, I have an IC-705 that shares 
my four keys, antenna, and MLDX.

Re: [Elecraft] switchbox KX3 to signalink/mike+headphones

[James Bennett via Elecraft]

For sure - I’d like to switch my Yamaha CM-500 headset between my K4D and an 
Icom IC-705. I currently have to use two separate headsets - a PITA to say the 
least.

Re: [Elecraft] KPA500 / 270V ERR

[James Bennett via Elecraft]

Folks - I’ve exchanged email with Rob at Elecraft support. He tells me that a 
failed R16 on the power supply board should have no effect on the 60V supply, 
so I’m opting to NOT rip the amp apart in search of R16. Waiting on Rob to send 
me an RSA and the amp will be off to Watsonville for some first aid. I’ll post 
back here when it is returned and let you know what went south.

[Elecraft] KPA500 / 270V ERR

[James Bennett via Elecraft]

Hi - I’ve had my KPA500 serial number 3645 for several years and until today 
have had zero problems with it. Previously it was driven by a K3; currently 
(until today!) a K4D. Last time I used it, it worked great. Today I powered it 
on after having it off for several days and when I went to Operate mode, I got 
the dreaded 270V ERR display. When I display HV it shows “1”. Everything else 
seems to be OK - band changing works fine, metering of the power and frequency 
are OK - just can’t go to Operate mode. The top cover is on just as tight as it 
has been for years. Fuses are all OK.

Looked through the archives and did see a few hits, but most were related to 
loose top cover or incorrect voltage settings.

I’ve fired off an email to Elecraft support earlier today but thought I’d run 
it by the owner community too.

Suggestions?

[Elecraft] OT FS Mosley Mini-32-AW HF Yagi - New In Box

[James Bennett via Elecraft]

Hi folks,

A few months ago I posted this antenna for sale but got no takers. I still have 
it and would really like to get it sold and out of my garage. Here is my 
original post, slightly edited:

"I’m selling a brand new, never out of the box Mosley Mini-32-AW two element 
yagi. The antenna covers 20-17-15-12-10 meters. It is a two element yagi on 
20-15-10 and a rotatable dipole on 17 and 12 meters. Boom length is 6 feet. 
Longest element is 19.7 feet. Weight is only 12.5 pounds.

I ordered this antenna prior to making a decision to move to Idaho in 2020. 
Once paid for, that was it - no refund, no exchange, so I had to accept it. 
Thought maybe I’d have a home here in the Boise area where I could put it up 
but unfortunately my XYL talked me into buying a new home in an area with 
strict CC regs against any outdoor antenna. I wound up with a ZeroFive 30’ 
Flagpole Vertical that works very well. 

Anyway, I need to sell this nice Mosley yagi. As I mentioned, it has never been 
taken out of the box. It comes with the original manual, the Mosley 
registration card, and my sales receipt. My cost was just over $600. If you 
order a new one, you’ll have a manufacturing wait time of three months or more, 
and the prices have gone up.

I’ll sell this one to you for $500, shipped at my expense. If you prefer to 
pick it up in person I’ll knock $25 off the price.

PayPal or cash, please. Contact me at: k7...@arrl.net

Re: [Elecraft] WTB: K4

[James Bennett via Elecraft]

Very true, but worth asking. That is exactly how I managed to get my K4D #636 
last month. The one I had on order was scheduled for a Nov-Dec delivery and one 
came up for sale here on the reflector. It took me about 2 microseconds to 
reply and claim it. Glad I did - it is a pleasure to use. And I’ve found 
absolutely zero faults with it. It was a simple plug and play, replacing my 
trusty 10 year old K3. Love that mini Pan!

[Elecraft] Stamps

[James MacMillan]

My dad W8ZEQ was also a stamp collector. 
When the band was open in ‘57 he worked I1FT/Egone a few times. He introduced 
him to his neighbor Alvase another stamp collector. For over a decade envelopes 
of US and Italian stamps crossed the oceans, stamps on the inside and outside 
faithfully mounted in albums. 

It was also the time a five year old began to pay more attention to the short 
waves. It was quite a journey from the Viking II to the KX3.

Re: [Elecraft] Collecting stamps vs. seashells -- and why this is not wildly O.T.

[James Bennett via Elecraft]

I can certainly relate to the parallels. I’ve been US stamp collected (and now 
online dealer) since age eight. My collection now is at the point where adding 
just about any stamp to a blank spot could run close to what it would take to 
buy a used car. Thus, the poor collection is opened only occasionally.

I’ve been hamming since age 16 as a novice back in PA. Still chasing DX, mostly 
on CW, but every once in a while on FT8. As opposed to those rare stamps, the 
rare DX costs next to nothing to acquire, save some time away from family 
matters. But the beauty of ham radio is that there are s many other facets 
of it besides DX’ing. One can collect counties, try for 9BWAS (Nine Band Worked 
All States), or even go for it with QRP. 

Lots of great reasons to get on the air and actually converse with people!

Re: [Elecraft] Tascam US-125M USB Sound Card for K3/K3S

[Elecraft] OT / FS: Tascam US-125M USB Mixer / Sound Card

[James Bennett via Elecraft]

Now that my K3/P3 combo has been sold and I have a shiny new K4D, I have no 
need for this Tascam sound card. I used it for years to run digital modes 
(JT65, JT9, FT8, PSK31) with the K3, a KX3, and a KX2. Works great! Included is 
the Tascam in the original box, a pair of audio cables (RCA connectors on the 
Tascam end; and Stereo TRS connectors on the radio end), and a USB A to B cable 
wrapped around a pair of 2.4” mix 31 ferrite cores to stop any pesky RF from 
getting into your computer.

Re: [Elecraft] PayPal holding payment. (Follow up)

[James Bennett via Elecraft]

However, one must take things with a grain of salt… my wife and I have used 
Facebook Marketplace over the past two years and are very happy with it. Not 
sure I’d buy something off of it without seeing / touching it, though. Prior to 
our move to Idaho in 2021 we had literally a ton of “stuff” we needed to get 
rid of, rather than moving it all up here. Tools, electronics, washer/dryer, 
basketball hoop, household items, etc. We put it on FBM and marked it as “Local 
Pickup Only”, cash or Venmo payment. We pocketed several thousand dollars prior 
to packing up our moving PODS.

After getting here we needed a couple bicycles for the kids - FBM again. You 
get to see it before handing over the green.

That’s my two pesos.

Steve - that did the trick. Just before I read your reply I came across the

I’ve got mine at 40 and it puts me one bar below the “5” mark.

Re: [Elecraft] K4 Data Mode Questions

[James Bennett via Elecraft]

Hi Dave - thanks for the reply.

Understood about #1 - I forgot that WSJT-X can force the radio to do stuff.

On #2, I use a Mac so things are a little different. The Mac has an Audio MIDI 
Setup application, and it appears to me that the USB Audio CODEC is set to 
maximum.

Anyone else have input on this subject as a Mac user?

[Elecraft] K4 Data Mode Questions

[James Bennett via Elecraft]

Two questions on using my new K4D for data mode, specifically, FT8.

First, with both VFOs set to DATA mode, no matter what I do I am only able to 
get two bars on the ALC meter. I read in the operator’s guide that I should 
keep it under the “5” mark. On my K3, I always kept four solid bars and the 5th 
flickering. Obviously two bars is wy under that “5” mark, but why, when I 
advance the MIC level from 1 all the way to max, does the ALC meter only stay 
at two bars? I am able to make contacts on FT8 so the thing is working, but I’m 
puzzled. Should I be able to get more than two bars of ALC in DATA mode?

Second - the K4 seems to think for itself. After scratching my head regarding 
that ALC level issue, I decided to try using USB mode. I put both VFOs into USB 
and…… this sneaky radio automatically switched both of ‘em back to DATA mode as 
soon as I transmitted. Is that normal / expected?

[Elecraft] OT: KWM-380

[James F. Boehner, MD via Elecraft]

I'm sorry you had so much trouble with your KWM-380.  My experience is quite
the opposite.  I did send mine to be completely refurbished and calibrated
and it is easily the quality of my KWM-2A and more.  Techs who work on the
KWM-380 are listed on the Collins Collectors Association website.  I used
Bob Struk KX6K.

Sorry about the off-topic post.

The KWM-380 may have been a "hot radio" in some people's minds, but I can
personally attest to the opposite.  I have one, along with a number of
KWM-2As and S-Lines.  The 380 is a horrible performer.  The receiver is
incredibly noisy, obstructing reception of all but the loudest signals.
The audio is distorted and filtering is poor.  Collins' last hurrah was a
dud.

Hi Ed,

I don't recall ever telling you this but your 380 also had horrible TX phase
noise. In the early 80s, we were located within 5 miles of each other in CO,
both running amps. Whenever you transmitted on 80 or 160, the phase noise
would cover the entire CW bands. I don't recall what you replaced the
380 with but I was a very happy camper when you did!

I take pride that my KSYN3A-updated K3 is still one of the cleanest CW
signals on the bands.

Re: [Elecraft] KPA500 Issue

[James Bennett via Elecraft]

No - it does not spontaneously go into transmit more. The problem is that on 
the non-Elecraft radio, placing the KPA into transmit mode (with a button push 
on the KPA) drops the non-Elecraft radio’s receive signal tremendously. See 
Jack’s explanation in an earlier post on what the K3 is doing to the “system” 
when it is powered off.

Re: [Elecraft] KPA500 Issue

[James Bennett via Elecraft]

Chuck,

Just gave it a try. No joy, same result - lowered rx signal strength on the 
IC-705.  Jack indicated that the K3 sets the Vcc rail to zero volts on power 
off, and that is causing the amp to go into Operate mode. 

I see the following options -

1. Always put the K3 on the same band as the IC-705 if I want to run QRO with 
the 705.

2. Never use the 705 in QRO mode.

3. Disconnect the K3 from the system, sell it, wait for the K4D to be 
delivered, and use the 705 all by itself with the amp and tuner in the mean 
time. 

Option #1 works but is a minor PITA. Option #2 - maybe. Option #3 - probably 
the choice to make, as the K3/P3 was going to be sold anyway, in anticipation 
of the K4D arrival. Just hoping I’ll live long enough to see the new radio 
delivered.

Oh well, nothing in life is simple. At least I’ve got options and am able to 
get on the air. :-)

Re: [Elecraft] KPA500 Issue

[James Bennett via Elecraft]

Jim,

I don’t think this is the same problem as you had. The receive signal on my K3 
does NOT drop off when placing the amp in OPER. With my antenna switched over 
to the IC-705 (not the K3), the received signal does drop off when the amp is 
placed into OPER mode. Thus, I’m pretty certain that R7 and the PIN diodes are 
OK - the K3 is not affected.

Re: [Elecraft] KPA500 Issue

[James Bennett via Elecraft]

Well, it looks like there is no simple solution to this dilemma. I was hoping 
to (easily) be able to use the amp with either rig while both were here in the 
shack. Pulling the audio cable when I want to use the IC-705 with the amp isn’t 
practical due to the location of the radio. I changed the “Radio” setting from 
K3 to Analog and Serial, but with the cables attached, the result is the same - 
as soon as the amp is put in OPER mode it goes into transmit state (* showing 
on the LCD). 

So, the only option for the time being is to always have the K3 powered up and 
on the band that I want to operate the IC-705 on. Just need to keep their 
frequencies separated as much as I can. Unless Jack comes up with an 
alternate…! :-) :-)

Re: [Elecraft] KPA500 Issue

[James Bennett via Elecraft]

Bob -

The * appears when I key the K3 and the amp is in operate mode. Likewise if I 
key the 705 and the amp is in operate mode, with the K3 powered on.

If I power off the K3 and place the amp in operate mode WITHOUT KEYING IT, the 
* appears, so you are correct - the amp thinks it is being keyed.

There is a jack on the 705 that allows one to key an external amp. I have that 
line running to the amp. Disconnecting it makes no difference the * appears as 
soon as I put the amp into operate mode. If I power on the K3, this does not 
happen. However, with the K3 powered on and that cable disconnected, the amp 
does not key at all, so it is working as expected - but only with the K3 
powered on. Somewhere the K3 is getting its foot in the door when powered off…

Jim / K7TXA

p.s. do you have any idea what Jack was talking about when he said "switch the 
RADIO setting of the KPA from K3 to something else, either Serial or Analog”??

Re: [Elecraft] KPA500 Issue

[James Bennett via Elecraft]

I was unable to try Jack’s suggestion of disconnecting the AUXIO cable - doing 
so made the KPA5000 not able to go into Operate mode. So, I wanted to do the 
other option he mentioned - changing the “radio” setting of the KPA to Serial 
or Analog. Unfortunately, I have no idea where that setting is. It isn’t in my 
version of the KPA Utility: V1.19.9.6. I sent Jack an email about it but he’s 
evidently off-line. Anyidea where that setting might be found?

My KPA shows the correct band on its display. The failure ONLY happens with the 
K3 powered off. When it is powered up and set to the correct band, the audio 
level in the IC-705 does not change when switching the amp from operate to 
standby.

[Elecraft] KPA500 Issue

[James Bennett via Elecraft]

Having an issue with my KPA500 and a non-elecraft radio. I’ve got an Icom 
IC-705 connected to my KPA500 and KAT500. By dropping the 705’s output power to 
4 watts and pressing Tune on the KAT500 with the amp in OPER mode, I’m able to 
get the tuner to give me a good match on just about all bands to my Zerofive 
Flagpole Vertical. Then, turning the power level up to max (10 watts) on the 
IC-705, the amp gives me anywhere from 210 to 250 watts output, depending on 
the band. And that’s fine for me right now.

However, what I’m seeing is that when the amp is in OPER mode, my receive 
signal strength drops way, way off to the point I have to go full AF volume to 
hear signals. If I put the amp in STBY, signal levels go back to normal. I also 
notice that the amp fan doesn’t take too long to crank up to high speed, and 
the PA temp is sitting around 67 C. 

I also have a K3. When I power up the K3 and switch the antenna over to the K3 
on the same band as the IC-705 - there is no drop in signal level on it when 
switching between OPER and STBY on the amp. And, yes, when I’m using the 
IC-705, I press the corresponding BAND button on the amp.

OK - some further info: if I have the K3 sitting on the same band as the IC-705 
this does not happen - going from STBY to OPER on the amp makes no difference 
on receive level on the IC-705. But if I power off the K3, the IC-705 reverts 
to its partially-deaf state.

Somewhere long ago in a far distant galaxy, I recall Jack W6FB mentioning that 
the K3 pulls some signal to zero when it is powered off. I suspect that may be 
what is happening here but for the life of me I can’t recall the exact 
conversation. I’d like to get to the point where I can run the IC-705 with this 
tuner and amp without having the K3 in the equation, as the K3 will be going on 
the sale block in the near future, in anticipation of a K4D delivery. 

Any ideas?  Jack - are you listening? :-)

Jim / K7TXA

[Elecraft] OT: KWM-380

[James F. Boehner, MD via Elecraft]

OK,

I know this is the Elecraft list, but since the topic of the Rockwell-Collins 
KWM-380 seems to be of interest, I have one (serial number 14), and yes, it is 
no comparison to the rigs of today, especially the K4.  It was introduced at 
the 1979 ARRL Midwest Division Convention in Cedar Rapids, IA with a price tag 
of $2,995 without options.  Using an inflation calculator would put it at 
$11,704 in today's dollars, fairly close to the cost of an ICOM IC-7851.  It 
really is a sweet radio, and VERY fun for non-competitive operating.  It truly 
was ahead of its time.  Only 3000 of these units and the HF-380 (its commercial 
cousin) were made.  Production ended in 1986, and was the last amateur radio 
unit made by the company.

I don't want to continue an OT discussion here, but if you have an interest, 
please look at my QRZ.com page for a few pictures.

There's not a lot on the web re: KWM-380 except for sales.  I recall little 
about it except that it was very expensive for the time.  I think the KWM-2 
went for about $1,500 new? in the 60's, that would be about
$15,000 in today's money, although it wouldn't be an attractive transceiver in 
today' world.  But, a -380 was a pretty hot radio in those days.

[Elecraft] OT FS: Mosley Mini-32-AW HF Yagi - New In Box

[James Bennett via Elecraft]

I’m selling a brand new, never out of the box Mosley Mini-32-AW two element 
yagi. The antenna covers 20-17-15-12-10 meters. It is a two element yagi on 
20-15-10 and a rotatable dipole on 17 and 12 meters. Boom length is 6 feet. 
Longest element is 19.7 feet. Weight is only 12.5 pounds.

I ordered this antenna prior to making a decision to move to Idaho last autumn. 
Once paid for, that was it - no refund, no exchange, so I had to accept it. 
Thought maybe I’d have a home here in the Boise area where I could put it up 
but unfortunately my XYL talked me into buying a new home in an area with 
strict CC regs against any outdoor antenna. I wound up with a ZeroFive 30’ 
Flagpole Vertical that works very well. 

Anyway, I need to sell this nice Mosley yagi. As I mentioned, it has never been 
taken out of the box. It comes with the original manual, the Mosley 
registration card, and my sales receipt. My cost was just over $600. If you 
order a new one, you’ll have a manufacturing wait time of three months or more, 
and the prices have gone up.

I’ll sell this one to you for $525, shipped at my expense. If you prefer to 
pick it up in person I’ll knock $25 off the price.

PayPal or cash, please. Contact me at: k7...@arrl.net

[Elecraft] OT FS: Multiple Shack/Rig Accessories

[James Bennett via Elecraft]

Trying to do some spring cleaning in the shack - hey, it IS spring, right??? :-)

Prior to my move out of CA, I had a solar panel in the yard, feeding into the 
shack where I had a MorningStar PS-15M solar charge controller and a bank of 
AGM batteries. I also used the KI0BK Low Loss PWRgate sold by Flint Hills Radio 
sitting between the battery and an MFJ 4245MV power supply. And…… I used an 
N8XJK Boost Regulator (with separate meters) to keep a constant 13.8 volts 
going to the station equipment. Well, I no longer have the batteries or the 
solar panel, so the charge controller, PWRgate, and boost regulator are just 
taking up space. Out they go!

One other item I no longer need is a Pignology PIGLET. I used this to “connect” 
my now-long-gone KX3 to my laptop when operating away from the shack. 

Prostar Charge Controller PS-15M with original manual: $90

KI0BK PWRgate: $25

N8XJK Boost Regulator with Remote Meter Panel Model R-1: $150

Pignology PIGLET: $25

Items will be shipped FREE to any US address.

p.s. - the boost regulator comes with cables wrapped on 2.4” mix 31 ferrite 
donuts - there is ZERO hash generated on the ham bands with these donuts inline!

[Elecraft] question on KXPD2

[James Cizek]

I all,


I recently picked up a KXPD2 knowing I could use it on my existing KX3 and
will work on the KX2 once I receive it.

I am not sure if I am missing something, or there is a manufacturing
problem, or it's just the way it is.   Are the paddles supposed to have a
ton of vertical play/slop in them?  The screws that come up and down from
the outside into the paddles that act as the bearing points slide around in
the holes like crazy.  When you attempt to key you can see them move at 45
degree angles as if the hole they are in is drilled out too big.  Is that
normal?

One paddle has about 1/8" vertical movement, the other almost a full 1/4".
It's hard to key quickly on these because they move all over the place.
The strange bearing slop is also causing me to be unable to adjust equal
pressure on the paddles.  Since you press one side and they both move, you
cannot get the spring pressure equal since they move a different amount
left and right.

I realize these are "field equipment' and not intended to be a finely tuned
precision device, but the way they move around so drastically makes it
unusable.
Just wondering if this is the way these are designed or if I need to call
Elecraft and ask about it!

Thanks.

[Elecraft] K3 to K4D "Upgrade": Satisfied?

[James Bennett via Elecraft]

Am considering selling my 10 year old K3 (dual receivers, internal tuner), and 
P3 and ordering a K4D.

If you’ve gone down that path and have received your K4, how do you like it? 
Are you glad you made the “upgrade”? Do you notice any, if at all, difference 
in performance? My K3 works fine but I’d like to get a new rig before parts to 
repair the K3 become completely unobtainable should something rude happen to 
mine.

Re: [Elecraft] KX2s

[James Cizek]

Mike, you confirmed what I had been wondering about.. and it sounds like
the radio will ship without the mic which is just awesome to hear!

Thanks for the info. Glad to hear things are still rolling out the door at
whatever pace they can get the parts in.

Have a great weekend all, and GL in WPX if you are participating!

Re: [Elecraft] KX2s

[James Cizek]

Thanks all,  I must have missed the post from Wayne.

Thank you all for the input, sounds like it's not just mic parts holding
things up, everything is held up.  No surprise with the way the world is
today.  I work in IT for a living and we are experiencing 8+ MONTH delays
in getting servers/storage now so I think the delays are something we must
all get used to until things recover.

Thanks for the comments.  I really didn't want to bug anyone at the factory
with a "me too" question :)

[Elecraft] KX2s

[James Cizek]

Hi all,

In an effort to satisfy my "kid in a candy store" anxiousness without
calling Elecraft and adding to the probably hundreds of calls they get
saying "Where's my radio", I thought I'd inquire here first :)

A friend and I ordered KX2s mid-December. At the time, the estimated ship
date was 6 weeks.  I know that Elecraft is probably having a heck of time
getting parts just like everyone else in the world.

But I noticed that the MH3 mic was out of stock with no estimated ship
date.  I wondered if it was the mics holding up the "shack in a box"
deliveries or if the radio parts are still that far behind also.

So, just a general question here,  has anyone received a KX2 recently?
Wondering if they are dribbling out of the factory or just plain stuck
waiting for parts!

Only 6 weeks of SOTA winter bonus points left so I am anxious to take my
new toy to the mountains when it arrives :)

Thanks

Re: [Elecraft] [OT] Loss in window line [OPINION] [LONG]

[James Bennett via Elecraft]

Al, 

I don’t disagree with you at all, but I do want to make a comment. After having 
used coax, “open wire” line, and window line in several locations I think I can 
add to the discussion. Many folks have antenna tuners that “remember” the L/C 
combination for “segments” of each band they operate on. Those memories are 
quite handy when one is moving about the bands - change frequency and the tuner 
dutifully sets the L/C combination to match what was used the last time at that 
spot.

Unfortunately, there is a big difference in those settings between wet and dry 
window line. If you’ve “trained” your tuner for a bazillion segments across 
each ham band in dry conditions, you can rest assured that when it is 
pouring-ass raining outside those settings go out the window (no pun intended). 
It is for that reason that, back at my previous QTH in Northern California, I 
removed 110 feet of window line feeder and replaced it with open wire line on 
my 88 foot long doublet. I had put the antenna up with window line in the 
summer and all was fine - until the rainy season started. After the rains 
started I could forget using the stored memories in my various “auto tuners”. 

So, yes - window line is OK but be prepared to re “tune” your match when the 
window line gets wet. I, for one, will not use the stuff again.

Re: [Elecraft] RFI

[James Bennett via Elecraft]

Same issue here - our CC specifically say no outdoor antennas

 However, another thing to consider is to use a flag pole style antenna. I 
understand that many states’ laws have provisions that prevent any HOA from 
denying the installation of a flag pole in one’s yard. I know for a fact that 
my state (Idaho) is one of them. I was initially going to put a PVC jacket 
around my 6BTV and make it a flagpole antenna. But after being here for several 
months realized that the winds in this high desert environment would have 
destroyed it without guy wires. And who has seen flag poles with guy wires? So, 
I purchased a Zerofive HOA 24’ Flagpole Vertical, covering 40-6 meters. The HOA 
had no problem with it and I’ve been on the air for months with the flagpole. 
It even loads up on 80 and 160 meters. Not inexpensive but to me, worth every 
penny. There are other commercial ham flagpole verticals on the market. No need 
to be limited to indoor antennas if you have a yard to put up a flag pole!

[Elecraft] K2 new kit question

[JAMES GUNNOE]

Good morning everyone.
I have finished the basic CW version and all my checks and alignments are good.
The question I do have is, the capacitors (101) tan in color, have the legs 
bend in a zigzag pattern. When I tried to straighten them I ended up cracking 
the ceramic insulation on them. So I replaced them and installed all of them 
without straightening the legs. That of course put them a bit tall on the 
board. The manual states to install all components as close to the board as 
possible, to avoid stray RF coupling on the board. 
Do you all think the way I installed them is going to be an issue? And how 
would I be able to tell if it is a issue?

Thank you for all the help I have received so far from this group.

Re: [Elecraft] Parts availability

Reactionary, my left foot!  What happens the next time something like this 
happens (and it will but who knows when).  My suggestion centered around 
determining what is necessary to ensure that we continue to enjoy a semblance 
of normalcy when something happens.  For instance, if the US were to have a 
falling out with China trade wise where would we get the necessary electronics 
and other high-tech items essential for our economy to function.  Can we 
produce these essential items in CONUS?

We had the luxury of a reasonably vibrant manufacturing base prior to our entry 
in WWII but it still took time (at the cost of lives) to get production cranked 
up to meet the demand.

parts, and I'd bet that the contractual relationships that major JIT
manufacturers have with their suppliers means that they are going to get
their parts before the ones who don't.  Who do you think is going to get

Re: [Elecraft] Parts availability

[James Driskell]

Unfortunately, the "Just In Time" concept that many US manufacturers have built 
their businesses around never considered the "you're never going to get it" 
approach that we now see.  I hope someone is taking a hard look at our national 
resource network because if the balloon goes up, we're going to have a hard 
time cranking up the domestic supply chain to meet our basic needs.  We 
probably won't have the luxury of being able to take our time to get it running.

Subject: [Elecraft] Parts availability

Recently I tried to order some electronic parts for a project I am
working on.  In the old days (like, a year ago) I would just get on the
Digi-Key web site, order what I want, and it would arrive in the mail in
a few days.

These days, there are a LOT of parts on the Digi-Key web site that show
no availability.  I wanted to buy 10 standard, run-of-the-mill LM358
op-amps in an 8-pin DIP package.  This is a 25 cent part that has been
around for decades.  They had none in stock in that quantity, from any
manufacturer.  I ended up ordering a couple in the old-fashioned TO-5
metal can package for *10 bucks each*. At least they did have some of
those in stock.

I also wanted to buy a ceramic capacitor assortment.  They listed 6
assortments that would have worked for me, but all were out of stock.

Manufacturers with "just in time" parts ordering systems are in a world
of hurt these days.  Fortunately I don't think Elecraft ever went down
that path.

Problem solved - it was simply a matter of upgrading to version 2.5 of WSJT-X. 
Works fine now. Thanks to all who replied!!

Re: [Elecraft] K3 / WSJT-X Delayed Transmit

[James Bennett via Elecraft]

David -

I’ve played with the VOX Gain to no avail - at zero the rig never transmits, 
and at 100 (where it has been sitting) I get the delay. Various settings in 
between have no effect. The Delay controls how quickly the rig goes back into 
receive mode after speaking. But, thanks for the hints!

[Elecraft] K3 / WSJT-X Delayed Transmit

[James Bennett via Elecraft]

Hi Folks,

Wondering if someone on the list might be able to solve this one. I’m using a 
K3 and while CW is my main passion, I do dabble in FT8 occasionally. I’ve 
noticed that the radio does not start transmitting right at the start of the 15 
second FT8 cycle. It will start anywhere from 2 - 5 seconds into the cycle. I 
can’t help but think that is not a good thing and could be the cause of an 
occasional missed QSO. I DO make QSOs but this kinda bothers me. The audio 
signals are delayed this amount of time, as is the red TX light coming on - I 
am using VOX . Same thing happens when I press the TUNE button - it takes 
anywhere from 2-5 seconds for the rig to go into transmit mode.

I really doubt it is due to computer overload, as the only applications running 
are WSJT-X, MacLoggerDX (my logging program), and JT-Bridge  - all other 
applications have been ended. Since this happens when I press TUNE, that pretty 
much eliminates JT-Bridge and MacLoggerDX as the cause. Some hardware and 
software specifics:

Mac mini, 32 GB RAM, 3GHz processor, 6 cores, Intel Core i5.
Mac OS Big Sur 11.5
WSJT-X 2.4.0
Audio Interface: Tascam US-125M external USB device
Values in the DT column are consistently about 0.1 - 0.4

Wasn’t sure if I should post this here or on the WSJT-X list, but I thought I’d 
start here. Any ideas?

[Elecraft] P3 Acting Wonky

[James Bennett via Elecraft]

Hope someone can help me out on this one. I just moved into a new home, 
relocating my station from CA to ID. Got the K3/P3/KAT500/KPA500 all hooked up. 
All was working fine at the previous QTH. Now, the P3 is not showing me any 
signals. The “signal level” is below S0. I have an IC-705 that I key up at 10 
watts into an inside dipole. It registers 60 over S9 on the K3 meter, but not a 
trace of signal showing on the P3. The frequency display on the P3 is spot-on 
with what the K3 is set to. If I turn on marker A on the P3 then tap to QSY, 
the K3 obeys and follows. That kinda tells me the cabling between the two is 
OK. 

So, why do I not see any signal at all on the P3? Pilot error? Could be, but 
where…?

[Elecraft] FS: Mosley Mini-32-AW 2-El, 5-Band Yagi

[James Bennett via Elecraft]

Moved to Idaho into a HOA/CCR development last month after having ordered this 
nice HF yagi. It has a six foot boom, with two elements, max element length is 
19.7 feet. It uses two elements on 20, 15, and 10 meters. On 17 and 12 meters 
it functions as a rotatable dipole.

The box has been opened, but the antenna items have never been taken out. Comes 
in the original Mosley box, with original manual and registration card. New 
orders at Mosley take up to three months for shipping, so you can get this five 
band yagi NOW!

Local pickup only - I am recovering from a heart attack and have no way to get 
it ready for UPS or FedEx pickup.

A new one from the factory will set you back AT LEAST $600 including shipping. 
You can have mine for $550. Again, local pickup in the Boise, Idaho area only.

I accept cash or PayPal. Please contact me off list: w6...@mac.com 
 (I changed my call to K7TXA shortly before moving to 
Idaho - changing my email address is nearly as difficult as moving!)

Re: [Elecraft] Ground Wire & Coax

[James Bennett via Elecraft]

Folks - thanks for the input! 

Jim - Not sure what version I’ve got - it doesn’t say, so perhaps it is first 
edition of the book. However it does have a few paragraphs on perimeter 
grounding, on pages 4.22 - 4.24. And yes, I had planned on a series of ground 
rods driven in and connected to the #4 wire along its path to the Ufer 
connection point. 

You mentioned “at least 1.5 - 2x their length" of the ground rod spacing. What 
would be the minimum spacing between rods? They are, after all, not the easiest 
things to “push” into the ground.

Luckily we’ve got no Telco line coming into the house, nor CATV - it is all 
fiber here.

[Elecraft] Ground Wire & Coax

[James Bennett via Elecraft]

Got a question for those folks who are knowledgeable in grounding equipment.

I’m installing a Zerofive flagpole antenna in my backyard. There will be 
several 8’ ground rods at the antenna site. On one side of the house is my 
shack; on the other side is the home’s utility ground - a Ufer system. I’m also 
installing a KF7P entrance panel on the exterior wall of the shack. It’ll have 
several lightening arrestors and a very close-by 8’ ground rod. Per N.E.C. 
specs, I need to tie the ground system at the shack entrance to the house 
utility ground - probably 150’ or so from the coax entrance panel to that Ufer 
spot. My electrician said that a #4 solid copper wire running from the coax 
entrance panel to the Ufer point would suffice for keeping the grounds 
together. Looking at the ARRL book on grounding and bonding, it appears that 
what I’m going to do is to install a “perimeter ground.” Not cheap, but the 
right thing to do.

Anyway, the path from that coax entrance panel to the antenna is about 100’. 
The first 50’ of it is the same path that the #4 copper wire would take. Since 
the ground here in SW Idaho doesn’t freeze up, I’m looking at digging a 4-6” 
deep trench for these wires. Is there any reason why I cannot place the coax 
and the #4 copper wire in the same trench? Electrical reasons? RF reasons?

Re: [Elecraft] T1 Tuner Question ?

Paul,

I believe you should hear a few relays click. If you are connected to a load 
that the T1 “knows” there may be no click. You can test that by using a 
different antenna or a dummy load.

Re: [Elecraft] Plug on KPA-1500

[James F. Boehner, MD via Elecraft]

David, I was hoping someone from Elecraft would have stepped in to answer your 
question.

I assume you are in the USA.

My KPA-1500 came with a 6-20P 240V plug like here:  
https://shop.worldcordsets.com/shop/categories/NEMA-620P-Power-Cords .  Your 
picture did not come through, so if your plug is different, I would contact 
Elecraft.

I was not aware that Elecraft has ever meant the amplifier to be operated on 
120V, at least from what the specs say.  Elecraft would know if your amp was 
wired for 120V.

If your plug is similar to the ones on the link, I'm concerned why the 
electrician would have said that it was a 120V cord.  The 6-20P is definitely a 
240V (USA) plug.

If all else fails, ask him to install a 240V 6-20P outlet for you.  Again, do 
contact Elecraft if your plug is different from the link above.

the shack to fit the plug coming from my KPA1500, the electrician tells me that 
it is a 120 V plug, and that is it against the law for him to wire a socket for 
that to 240 V.



Here is a photo of the power plug my KPA1500 came with:David F. Reed שָׁלום
