Re: [Elecraft] OT: High school drafting class,

[Grant Youngman]

I guess I missed out. Never had a formal course. No drafting in high school, 
and no drafting during undergraduate and graduate EE at Rice in the 60s. A 
straight edge and logic element templates in various sizes, were all the 
drafting skills needed. Board layout and a few other things were picked up as 
exercises for the the student.

Re: [Elecraft] Why is my K3 off frequency?

[Grant Youngman]

The other option if you don’t want to go through a REF CAL, is to simply tune 
to the NCS. Use the dial display to get close, and then, like the old days, 
ignore it and tune a few Hz until the NCS sounds right.

[Elecraft] Additional K4 Q Sessions

Re: [Elecraft] March/April NCJ

[Grant Youngman]

At least they just grumbled about your review.

I once posted to a reflector about (what was well known) buggy control firmware 
in a (non-Elecraft) radio.  (The “radio" part of the radio was fine, but 
sometimes you never knew what pressing a front panel button would break next).  
I almost immediately received a cease and desist letter via emai from the 
developer of said firmware, threatening a lawsuit based on potential loss of 
livelihood and reputation if I didn’t make a retraction.  I made a snark-laden 
public retraction on the reflector, which I’d guess was lawsuit worthy in 
itself.  But I guess that was enough.  I never heard from this person again.

I eventually just got rid of the radios and moved on …. life is too short.

Re: [Elecraft] QSO Today Virtual Ham Expo this weekend

[Grant Youngman]

Obviously the Virtual Hamfest is having some issues.

I was always able to get to everything except the lobbies and booths.  Got an 
email last night, instructing an email to supp...@qsotodayhamexpo.com if there 
was an issue.  Did that.  Received a reply quickly that it was fixed.  But it 
wasn’t.  Reset my ticket as indicated in this morning’s email.  That didn’t 
help either.  Sent a second email to the support address this morning telling 
them it still wasn’t working.  A few minutes later it had actually been fixed.

Apparently some bottom feeder decided to have fun, and, instead of just playing 
music or putting up a sweeper over the AM Window, QRM’d the hamfest site with a 
DDoS attack, which complicated things even further.

Anyway … it was a good presentation this morning, especially with Eric 
indicating they hoped to have Group #1 out the door by the end of May, +/-.  
That was encouraging news, especially if you were, like I was, a couple of 
months late to the party.  I may still live long enough to get my K4D :-)

There is another K4 Q session with Eric added to the schedule for 4:00pm EDT 
this afternoon.

Re: [Elecraft] Buyer Beware!

[Grant Youngman]

This is not a bad joke. You're pointing fingers in the wrong place.  As is 
typical with this scam (which has been ongoing for years now), the listed 
seller’s account has been hacked by a malevolent third party.  You can pretty 
well guarantee that the listing is fraudulent, and has not been posted by the 
seller shown with the ad.  Odds are he doesn’t even know it’s out there. It may 
be that seller’s account, but it isn’t that guy.

Re: [Elecraft] KPA1500 on AM

[Grant Youngman]

Precise calibration of a monitor scope isn’t that terribly essential. An SB-610 
or equivalent is hardly a precision instrument, but more than adequate.  The 
point of the scope is primarily to observe and prevent negative peak clipping, 
ensure you’re not out of headroom and starting to flattop on positive peaks, 
and adjust mic gain for something approaching 100% modulation.

Actually, that assumes that peak to avg is exactly 4.  Which it rarely (never?)

Aside from the legal (and oft disputed) aspects of AM power limits, you’re 
better off being conservative and setting drive levels for something under 375W 
carrier from the amp.  Maybe 250-300W.  That will ensure you have some headroom

Re: [Elecraft] Can I rent a K4?

[Grant Youngman]

Elecraft already has a reasonable return policy.  It’s on the website.  30 days 
and a 10% restock fee (which may be more if you’ve bunged it up), since they’d 
most likely at least have to clean off your fingerprints and lord knows what 
else, refurbish and then resell it at a discount.  And if you’ve run over it 
with a truck, dropped it in a river, or treated it to a dose of hamification, 
you’ll get your junked radio back instead of a refund.  PS — it doesn’t apply 
to kits that have been partially or entirely built.

If you buy one and don’t like it, it should be pretty easy to find potential 
buyers willing to throw money in your direction …

Re: [Elecraft] K4 Panadaptor Display

[Grant Youngman]

I display, whether physical or logical (e.g, a quadrant of a real display), 
only supports a single input — it has no means to “window-ize” multiple inputs.

Thinking about this some more, it seems it should be possible, eventually, to 
put a piece of remote software on the same machine that runs your other radio 
apps, and accomplish what you want to do. You can still only have one display 
controlled by one computer, but that one computer could be running multiple 
apps including a remote K4 display in a window.

Re: [Elecraft] K4 Panadaptor Display

[Grant Youngman]

This question was addressed during the recent Zoom presentation/Q  The 
answer is no — except.  

Some displays supports multiple video inputs that can be assigned to quadrants 
on the display.  So you could assign the K4 video stream to a quadrant 
(essentially a logical dedicated display), for example,  if your display 
supports that function.

and then K3S.  Scroll down.

It’s used for firmware upgrades, configuration save/restore and several other 
useful things, such as filter assignment by mode, etc.

Re: [Elecraft] Waaay OT: A new kind of QRM to be aware of ... warning issued by FCC today

[Grant Youngman]

I’m not at all surprised the FCC felt it necessary to make the statement they 
did.  And it certainly wasn’t limited to amateur radio licensees.

Anyone who has ever had a good chuckle or eye-roll over the “interesting QRM” 
Wayne referred to, should know why.  That QRM,  more and more often, also 
bleeds over into other places it doesn’t belong, like what should be apolitical 
reflectors.  It seems there is no longer anywhere we can get away from someone 
or some group airing their grievances wherever they are at the slightest 
provocation.

Do you have a computer somewhere else?  Connected to the internet?  You will be

Had you posted something else, or responded to another post on the list?  
Another possibility, unless the email was clearly directed personally to you, 
is that a list responder hit “reply to” instead of “reply to all”, so it only

Re: [Elecraft] KX3 sideband cancellation calibration

[Grant Youngman]

Ummm ..don't have a good answer for your specific question.  The last time I 
did it, I used an XG3 and calibrated each filter on each band (there are 
actually per-band phase/gain settings for each filter).

If you used an XG1 did you calibrate on the 40M fundamental, or was there 
enough 2nd harmonic to calibrate on 20M?  I found considerable differences in 
per-band gain/phase settings.  So it wouldn’t be surprising if the null depth 
is not quite as good on a band you had not specifically calibrated for.  And in 
some cases you could still barely hear the alternate sideband — but it was very 
weak in any case.

I also found that the automatic null routines didn’t always get to the deepest 
null.  Elecraft says that it’s (60+ dB) good enough, and it likely is from any 
practical view point.  But it was possible in some cases to improve the null 
slightly by a +/- 1 count manual adjustment of either the phase or gain setting 
after running the auto-null routine.  It varied by band and filter, and manual 
tweaking didn’t always result in any improvement.

Re: [Elecraft] Tuning Random-Length Wire Antenna with K3 Internal Tuner??

[Grant Youngman]

I can’t help but think we’re over-thinking this.

I think the original post was regarding ‘portable' operation.  When I go 
portable I don’t carry a large antenna with lots of wire or weight.  I usually 
carry a 41’ (non-resonant) wire with a 9:1 unun rated at 300w watts, and a 
throwing line and weight to get the far end of the wire up in a tree. I have a 
large OCFD and a 40’ fiberglass’s mast to get it up, but frankly, for quickie 
portable, getting the center pole staked and up and guyed is more trouble than 
its worth.  If it was for a weekend or a week, maybe.  But I’d rather spend the 
time operating.  I’ve used the simple wire with both a K3 and KX3 with internal 
ATUs.  Works fine.  Nothing has ever cooked.  The internal ATUs typically get 
SWR to 1.2:1 or better.  Feedline is 25 feet of RG-58 choked off a foot before 
the radio termination.

Sure, some power is getting lost in the tuner, the balun, the feedline, the 
connectors, human absorption, whatever.   But …

Re: [Elecraft] KX3 filter question

[Grant Youngman]

The introduction  the KXFL3 manual described these filters.

 
(https://ftp.elecraft.com/KX3/Manuals%20Downloads/E740165%20Elecraft%20KXFL3%20Option%20Rev%20A3.pdf)

They are not IF filters in the sense you may be used to.  In the KX3, selective 
filtering is done in the DSP.  These are roofing filters, at baseband, that sit 
in front of the DSP, and serve to improve the dynamic range of the radio.  They 
switch in automatically, and there’s no way to select them specifically (and no 
reason to).  But the display does show you what roofing filter is active.

Re: [Elecraft] Arecibo antenna collapses

[Grant Youngman]

I suppose the question is why not rebuild it if the capability (or an upgraded 
capability) remains of consequential value to the scientific community and 
there is no existing capability that can be cobbled together elsewhere to match 
it.  I don’t know what it would cost, but consider that one Virginia-class 
submarine costs well over $3B.  We build those, even if it is in small numbers. 
 It’s a matter of priorities … and pretty small $$ in the big picture.

hour at a time. They mashed my ears, hurt, and were tiring.   I ended up 
purchasing Auray Extra Deep Ear Pads for them (from BH Photo), which fit 
around,  rather than on, the ears, and they are much more comfortable — at 
least for me.  The pads increase sound isolation somewhat, and do slightly 
increase low end (no impact on highs that I’ve observed).

Re: [Elecraft] K3 Config and Main Menu Dump?

[Grant Youngman]

The easiest way to do this is simply to save the preferred/standard 
configuration using K3 utility.  And after other fingers have been at the 
radio, restore that saved configuration.  There’s no reason to have to look 
through individual menu settings.

Re: [Elecraft] K4 Headphones Q

[Grant Youngman]

While I realize that precision in statements is important … this is cutting a 
mighty fine point.  OF COURSE it’s the digital processing that causes the 
delays.  It’s perfectly reasonable to assume in this group that we know what we 
mean when we say that a “wireless” headset introduces delay, and we’re not 
talking about interplanetary communications.  Context matters, and the context 
of this conversation is Bluetooth headsets ...

Re: [Elecraft] K4 built-in operating manual now available

[Grant Youngman]

Even if you could do that, it might not be as useful as you expect.  
Sections/topics are linked from a main page and keywords, but not paginated.  
And there’s no page numbered “index” to help you get around.  This is more of a 
greatly expanded “help" function than a typically organized manual.  It would 
be hard to get around in it on paper, unless you did a lot of reformatting 
and/or indexing before printing it.

Just one though on the subject.

I believe Rose posted previously that she would not be making soft cases for

While I have both KX3 and K3/P3 DX cases from Rose, I’m probably going to

Re: [Elecraft] K4 mail filter for Thunderbird

[Grant Youngman]

If you can’t send posts with ‘K4' in the title or text to the trash, then 
there’s something wrong with your mail client's filter.  I’m not familiar with 
Thunderbird, so maybe there’s an issue there.

I routinely read maybe 20% of the posts I receive from the many (20+?) 
reflectors I subscribe to. (or .. 'to which I subscribe”,  to use what was once 
called proper grammar).  In any case, DEL is the best approach, like it or not. 
 I often read posts that some filter would have discarded .. and learn 
something useful.  There were even, at times, some senders who’s emails I might 
have filtered out.  But even those are, far more often than not, highly 
informative and useful, and I get past the occasional condescension, and don’t.

I know this isn’t what you wanted to hear.

Re: [Elecraft] K4 -- Spectral subtraction noise reduction

[Grant Youngman]

You can’t really compare an NIR-12 to a more current implementation.  The 
KiwiSDR algorithm runs on a BeagleBone processor with virtually no discernible 
artifacts.  The artifacts were the achilles heel of the NIR-12.  I had one for 
a while.  Never liked it.

Presuming Elecraft delivers what they have said they’re working on, it will be 
a great addition to the radio.

[Elecraft] K4 -- Spectral subtraction noise reduction

[Grant Youngman]

I’ve recently been exploring quite a few of the many SDR receivers on KiwiSDR.  
One of the (many) features of this system is an option to select spectral 
subtraction NR.

I’m now really hyped about the fact that this will be available at some point 
on the K4.  It works exceptionally well.  So well, that I leave it turned on 
most of the time.  Often, stations you can barely copy down in the junk 
literally pop up out of the noise.  Don’t know if this will be available at 
initial shipment, but it’s certainly something to look forward to if not.  I’ve 
only tried it on AM and SSB at this point, so not sure about CW.  

Just something else to whet the appetite for that eventual “you’re up” email 
from Elecraft sales …  :)

Re: [Elecraft] KX3 odd behaviour

[Grant Youngman]

There is an auto-mode for opposite sideband nulling to calibrate the KXFL3.
I’d have to look at the manual to remember the specific keypresses for this, 
but it does show progress in the display (phase and gain) while running through 
the procedure.  It is described in this document:  
https://ftp.elecraft.com/KX3/Mod%20Notes%20Alerts/RX%20sideband%20null%20A8.pdf.

Could that be what you put the radio into without knowing it?

Re: [Elecraft] Is the Lab599 TX500 a "rip-off" of the KX3?

[Grant Youngman]

There are going to be a lot of nice little radios. This may be a really good 
radio.  Do you know that?  I don’t.

Personally, I wouldn’t touch this thing with a 10 ft pole.  No battery; no ATU; 
unknown specs; unknown, if any, support; non-standard connectors that won’t fit 
anything else;  and on.  It looks “cool”, and that will certainly appeal to 
some.  But it’s more than the radio that has to be carried in the end, and 
doesn’t come from a trusted source with a track record.  Will you be able to 
read the display in the sunlight?

Re: [Elecraft] K4 info

[Grant Youngman]

I think a comment I made started this discussion.

I don’t have any problem with anyone setting up a group for anything they want. 
 If K4 users want a distinct group, that’s fine.  I’m a subscriber, too.

What happens more often than not, though, is that everything gets cross-posted 
anyway.  And the replies get cross-posted, and so on.  So thinking that you 
won’t see posts that don’t interest you on the main reflector because there 
happens to be a single-product group is a bit parochial.  And not everyone with 
an interest, or who might know something, is going to be a subscriber to the K4 
group, or vice-versa.  I do agree that I expect my delete key to be very active 
while everyone is bragging about THEIR K4 being shipped, and the unboxing 
videos, and the “first reaction” posts, and the issues people find, especially 
those related to the inevitable failures to RTFM, and all of that.  Anyone 
who’s been hanging around any new product-related reflector knows what to 
expect, such as long OT threads about 160M antennas, etc :-)

All of it is interesting.  The delete key (or its filter equivalent) can take 
care of what isn’t.  I’ve personally learned a lot from what seems to be OT 
posts, or posts about radios I don’t own, both here and on other lists/groups.

Re: [Elecraft] KX3 radio settings for WSJT-X

Sounds like you have RF getting in somewhere.  Given that the PC sometimes

Re: [Elecraft] K4 shipping info

[Grant Youngman]

PS.  Frankly, there’s no real reason for yet another group dedicated to one 
radio.  Many (most?)  of the posts to that group are replicated here.  And will 
have a wider audience of interested people here.

Too many groups, too little time to read them all ….

Re: [Elecraft] Seeking comments on Ham Expo from participants

According to a post by the organizers, there was even some cheating done to 
rack up scores to win a prize.  And those results had to be ferreted out and 
removed from the picture.  Sadly not surprising …

Re: [Elecraft] Seeking comments on Ham Expo from participants

[Grant Youngman]

I thought the Expo was excellent overall. I visited all of the booths, and 
watched maybe 80% of the presentations, both during the live event and 
afterwards.  Couldn’t have cared less about trying to earn points and winning a 
prize.  And of course the Elecraft events.

It was unique.   And except for not having a BA boneyard to wander through and 
take too much of my money, the best fest I attended this summer.  Well, it was 
the ONLY fest I attended :-)

Your presentation on the 3D KX2 design, was thoroughly enjoyable and very 
interesting.  Eric’s appearances— all three of the them — on the K4,  were 
informative.  I do wish the Q after Eric’s official Expo presentation had 
been posted to the web, and perhaps more so,  both of the extended 90 minute 
Q on the K4.  I learned something new in each of them.

I had some issues with the expo software itself, which I referred to the 
organizers as feedback in the questionnaire I received afterwards.  But they 
were largely minor, and mostly just navigation issues.

I’m looking forward to the coming one of these next year.  Mostly, I’m looking 
forward to my K4 :-)

Re: [Elecraft] Need a PX3 mini wireless keyboard

[Grant Youngman]

Yes, that’s it.  I misspelled TechNet ..  

Oddly, it’s 100% identical to the Anker I was using previously.  If it weren’t 
for the brand name on the keyboard and the product sticker on the back, you 
can’t tell them apart.  Except that there must be some difference in the 
character encoding that prevented the older Anker from working properly with 
the SideKar.

Re: [Elecraft] K4 Questions

[Grant Youngman]

I recall that Eric answered a question about that during one of the two 90 
minute Q at the Expo.

I think he said it may be available at some point, but indicated it was 
possibly over ethernet (?) rather than USB.  But I could be mistaken, since I’m 
lucky to remember my name unless I look at my driver’s license … if I can 
remember where that is :-)

Whichever it is, it didn’t sound like it was going to be a first release 
feature.

Both of the 90 minute Zoom calls hosted by Eric were informative.  There was a

I haven’t heard whether these recorded Zoom calls will be available for

Re: [Elecraft] K-4 and Expo

[Grant Youngman]

That announcement was made in the Zoom Q that followed, and during the 2nd 
Zoom K4 presentation Eric gave later in the afternoon.

It sounded like it might be well into or end of October to get the entire first 
order group out the door, give or take.  Partly dependent on supply chain, 
partly dependent on how COVID impacts go, etc.  Probably best to let the 
chickens hatch before trying to count them.

But it sure will be good news when the first production K4 ships … even though 
I’m too late in the list to have my address on that one.

Re: [Elecraft] KX2 3D/X-ray model live demo at QSO Today Ham Expo

[Grant Youngman]

Except for the indoor flea market, ability to knob twiddle, photos and a beer 
with friends, and the profuse sweat generated from trekking through the outdoor 
flea in 100 deg weather, 4 times, it’s starting to look like this Virtual Expo 
is going to be a great event.  Especially at the Elecraft booth …

Re: [Elecraft] K4 training

[Grant Youngman]

We agree.  But the transition from one essentially modern radio to another, is 
still mostly a matter of figuring out what each control does, where it is, how 
to read the display, and where to connect the antenna.  The exception I’d make 
is that if you gave a recently minted ham (or not) a Globe Champion 300 or even 
a Globe Scout he’d likely be completely mystified, and wonder where the RS-232 
interface and keyer speed control was.  THAT might take some training videos, 
or at least an elmer :-)

Re: [Elecraft] K4 training

[Grant Youngman]

It seems to me that if you need training classes or training videos to 
effectively use a radio, then that’s a problem — either with the radio’s owner 
(and I mean no disrespect to anyone) or with the radio.  

Elecraft will no doubt release some user tips for certain aspects of operation, 
just like they did for the K3 and other radios.  Many questions can be answered 
on the list, either by field testers, Elecraft, or others that get their hands 
on one before you do, like they always have been.  It isn’t a bad idea to 
collect these in a single location on the Elecraft website for reference, maybe 
organized by topic, provided that user submissions are vetted by Elecraft 
before they become gospel.

Oh, and none of the computers in my house have DVD drives any longer.  My 
grandkids have no clue what a CD/DVD even is. Which is why I’d suggest a web 
reference as a more universal option :-)

Re: [Elecraft] KX-3 Powered speaker suggestions?

[Grant Youngman]

I’ve tried several powered speakers on my KX3.   Currently, I use a 
(discontinued) Sony SRS-X33 I bought at Best Buy when I got the KX3 a few years 
ago.  I use it wired.  Plays really well if you EQ out all the low end.  It 
isn’t large, but it is relatively heavy.   Last year I dropped almost $200 on a 
highly recommended FOXL Dash 7.  While I really like how it sounds, and it’s 
slimmer and much lighter than the Sony and packs better in the Go Bag,  it’s a 
monster of an RF generator.  So it’s useless.  If your hand is anywhere near it 
you become the antenna.  Probably has a DC-DC converter in there that is 
completely unfiltered and unshielded.  The Sony is dead quiet.  I have another 
thingy around here somewhere, also recommended, and inexpensive, which is so 
flimsy I managed to break it after about a months use.  And the audio from it 
was thin and sub-par anyway.

All of that said, I’ve never had an issue with KX3-level RF getting into any of 
these.  I do use my KX3 at home, but even then it’s “backyard portable”, into 
simple wire antennas, without any concern about grounding/bonding/etc.  My wire 
antennas use the feed coax as the counterpoise, with a choke right at the KX3.  
 And I haven’t had any RF issues with any of these.

There may of course be other issues,  But it could simply be the speakers 
themselves.  The problem is you could try 5 of them before you find one that’s 
RF quiet and doesn’t act like a modulation monitor.

Re: [Elecraft] That's a whole lotta buttons and knobs!

[Grant Youngman]

When I was 12 in 1957, trying to decide what receiver I wanted, that’s how I 
evaluated them — count the controls and switches.  The more of those, clearly, 
the better the radio :-). :-)

Re: [Elecraft] KX3 Filter Question

[Grant Youngman]

It acts much like the roofing filters in the K3.  Sherwood measured the 
difference in dynamic range at 2Khz spacing as being an improvement from 96 dB 
to 104 dB.  There’s some degradation noted at 1 KHz spacing limited by opposite 
sideband rejection, but the footnote isn’t clear whether this was after per 
band opposite sideband null optimization or not, and the extent to which that 
matters with or without the filter module in place.

Re: [Elecraft] K4 feature suggestion

[Grant Youngman]

This isn’t a bad idea.  It’s the primary reason I normally don’t use VOX — 
especially with a headset mic, when you can’t turn away from the microphone for 
a cough, sneeze, or worse.  With a headset, I most always use a handheld PTT 
switch or foot switch.

In the days I had a substantial AM station I had a cough switch in the mic line.

Re: [Elecraft] K3s: microphone connector 8V current

[Grant Youngman]

i’m not interesting in using the 8V line for mic element bias.  That was 
someone else.  My application is to power an external device between a mic and 
a K3/K4 from that line.  

I can, of course, use a battery.  But it would be much simpler if the 8V line 
could supply at least 20ma without releasing smoke :-)

The individual that asked this question initially, was looking for the 
possibility of 50ma.

Re: [Elecraft] K3s: microphone connector 8V current

I have the same question about the current available for the 8V at the mic 
connector.  Is it limited to 10ma, or will it actually support a somewhat 
higher continuous current draw safely.  Not just for the k3, but also the K4.

Re: [Elecraft] SP3 intermittent A/B switch

[Grant Youngman]

Mike ..

This has come up before, at least once.  I think I’d try giving it a spritz of 
DeOxit and then working it a few times.  One suggestion was to run about 1ma of 
dc current through it and switch it a few times to clean it.  (I’m not sure I’d 
go that far, but it might work).

You can request the part number, price, and, I presume, stock status through 
the Support -> Parts Order From web-link, or just give them a call on Monday.

Re: [Elecraft] PX3 signal artifact - still seeking a solution

If the cable is shielded, and the garbage is on the PC's USB signal lines, an

not, but if it is, then the garbage may not be on the shield … and perhaps the

Re: [Elecraft] KX3 - Receive Opposite Sideband and I.F. Image Nulling question

[Grant Youngman]

I think there’s a problem with the instructions.  I could not hear a signal 
when the VFO was set 16 KHz above the KX3 frequency with RIT off as you say.  
But you will hear it with RIT turned on.

Re: [Elecraft] K3 Issue FIXED!!!!!

[Grant Youngman]

Glad to hear you got the problem solved, Ronnie,.   A properly seated TMP 
connector isn’t like to just pop out, even with the rigors of shipping.  So 
it’s a better than even bet it wasn’t properly seated to begin with.  If 
shipping actually did that to a seated TMP connector, you probably would have 
received a very non-rectangular radio with a forklift tine through the front 
panel :-)

[Elecraft] KX3 Opposite Sideband Null -- Follow Up

[Grant Youngman]

Six weeks or so ago, I put up a couple of posts asking if anyone had had an 
issue with opposite sideband null on their KX3.  I was having a problem getting 
a good null when FL3 was selected, although I had very deep nulls with FL2 or 
FL1.  I wasn’t motivated to check because of a perceived problem.  I had simply 
decided to rerun the null procedure on a “just because” basis, for the same 
reason any radio I own ends up on the bench periodically for a checkup and 
alignment. I didn’t get any response from the list, so I presume this isn’t 
something most have rechecked.

In any case, Elecraft support suggested my results indicated a defective KXFL3. 
 After receiving and very carefully installing a new one, sure ’nuf.  All is 
fine now.  My subjective impression is that tuning around with narrow CW sounds 
“cleaner” since I have a good null on all bands and all filter settings.

I don’t really know if the original KXFL3 was DOA (although it was no doubt 
checked by Elecraft prior to shipment), if it suffered a random or infant 
failure, or if I was careless with the KXFL3 board while doing the initial kit 
build a few years ago.  Could certainly and perhaps most likely have been the 
latter.

Calibration is probably worth doing once in a while anyway.  Components age and 
drift, and, no matter what, things just happen.

And I did get excellent support from Elecraft while working through the problem.

Re: [Elecraft] FT8 - was "On Second Thought, I'll Take The Stairs"

[Grant Youngman]

That’s definitely true.  Although I do have a gripe (is it FT4?) with the 
software that has arbitrarily plopped its users down in what was just a few 
months ago the home of mostly CW QRP activity on some bands.  There does seem 
to be a need for coordination.

Of course, I’m also old enough to remember, when SSB was beginning its surge 
because of the growing availability of good commercial gear.   At the time, SSB 
was mostly relegated to the lower 25 KHz of most phone bands.  AM ops would 
jump on anyone branching out from the then “SSB ghetto”.  Times change and 
nothing changes .. it just morphs into new groups co-opting spectrum from 
someone else :-)   Still …

Re: [Elecraft] New K144XV module installed no power out..

[Grant Youngman]

That makes it sound like there’s a problem with the antenna port … 

I don’t recall how the internal jack is situated for the antenna line — but you 
may want to be sure on all of these that when you inserted the TMP cable you 
didn’t miss the center of the socket and pushed it back instead of getting the 
tip of the plug fully inserted.  I found for a couple of them that the back of 
the socket is not well supported internally and was bitten by this problem.  I 
ended up using a thin bladed screwdriver to support the center of the socket 
assembly while inserting the cables.

Re: [Elecraft] Future of KPA500 & KAT500

[Grant Youngman]

I think a 500W-class amp is a good thing to keep in the product line, whether 
it’s the current KPA500 or KPA500A, or whatever.  Not everyone necessarily 
wants or needs a KPA1500.  The 500 watt amp is right in line with vintage gear 
like the 30L-1/SB200 — both VERY popular in their day (and still widely used) 
for good reason.  I could care less about either the size of the cabinet or 
less than an S-unit.

[Elecraft] Elecraft KX3 Support

[Grant Youngman]

Can anyone confirm whether or not Elecraft is currently providing support 
services for the KX3?  As of 5/11, they weren’t issuing RSAs for the KX3, but I 
wonder if they are currently providing email support or support through the 
“contact” web-form?  Trying to determine if support is temporarily on hold, or 
if the support inbox is overflowing, and need to remember that patience is a 
virtue …
