this is the Weber-Fechner law. It is claimed to hold true for physical
perceptions, e.g a blindfolded person’s perception of an increase in a
weight he is holding is proportional to the percentage increases, not to
the absolute amount of weight added.

Yep, I remember the thrills of hearing my first DX signals, many eons ago.
And there's still a certain adrenaline pop associated with hearing your
call come back, weak and with a hollow echo, emanating from an obscure
island and nearly covered by a howling pileup. I only need a small
remaining number of entities, but if I can't work them on CW I'll do
without.

Well, here's the flip side. My old qth was noisy enough, but the real
eye-opener came when I toted my KX3 to Hyderabad, India a few years ago. I
was teaching at the Indian School of Business and living in the faculty
apartments, and I had brought the KX3 along expecting to hear a bunch of
call-signs that would sound exotic to a midwestern Yank. So I strung up a
wire around the walls of my living room, up near the ceiling, and laid a
counterpoise out along the floor. Donning my headphones I switched it on,
looking forward to an evening of entertainment as I tuned 20 CW.
Zowie! What a cacophony of squeals, buzzes, crashes, honks and toots,
burps, whistles and grinds. The S-meter jumped up to about S9+10 and stuck
there. Nowhere on the band, it seemed, was there a slot wide enough for a
signal to peep through. Finally I was able to discern a little peep
half-buried beneath the layers of trash, a lonely VU2 calling CQ. I
answered him, but of course to no avail. On a later night I heard a few
words from a QSO between a local ham and a VR2 in Hong Kong, and that was
the sum total of my ham experience while there. Where were the noises
coming from? I dunno -- from everywhere, it sounded like.

The situation in the areas near and around the fires in California is
dreadful, although apparently improving some in the past days. My
daughter-in-law is a grad student at UC Davis (long way from Watsonville,
but threatened by a different fire); her apartment complex was on
evacuation alert for two weeks. The air was so full of smoke that they
couldn't run the AC, with daytime temperatures of 104 degrees. And they
were relatively fortunate, because the eastern edge of the fire that was
threatening them eventually was controlled, and the fire moved northward.
The smoke from that fire reportedly streamed east as far as Indiana. There
are fires in spots all the way from Bakersfield to Mendocino, an area as
big as some states. Much of California is a huge patch of dry tinder, for
the reasons Wayne pointed out in his post, and any lighting strike, any
sparking power line, any cigarette butt can set off a blaze that threatens
life and property on a mass scale. Viewed in perspective, the delivery
schedule of the K4 is a minor issue compared to the widespread havoc that
these fires have engendered.

Ha ha, yep. I worked DXCC as a Novice in 1957-58, all on 15 CW. It's true
that signals were popping in from all over the world at the time. But the
level and type of activity were completely different, of course. I worked
many countries still deemed to be rare via QSOs with local hams (e.g.
Johnston Island) or visiting scientists (e.g. Amsterdam Island), but only a
couple via DXpeditions (e.g. Navassa). Often you'd have an exchange of name
and qth, even with rare DX when others were waiting. You found DX by tuning
and listening, and most QSLing was via direct mail. A different world.
Now with clusters and micro-QSOs (5nn tu) you can knock off DXCC within 24
hours during a contest. Which is more fun? I dunno. Either way, hearing
your call come back from the other edge of the world can give a little jolt
of adrenaline, no matter how many times you've done it. I don't get any
jolt seeing my call on the FT8 scroll.

Yep. Well, we all have a life history with radio. Mine began with a
real-life crystal set, the kind with a chunk of galena and a whisker and a
coil wound over an oatmeal box. Later, a Meissner regen receiver. Still
later, my first transmitter was all home-brew, 6146 final -- worked the
world with it and a Hallicrafters SX-96.
I've tried FT8 and even WiresX, but neither one seems much like radio. The
digital qso via an internet gateway seems particularly pointless, sorta
like a zoom call with a completely random person. I guess I'm just old.

That is so true. As I've posted here before, the 99 bucks you spend for
EZNEC can be the best ham money you ever spent. Its educational value is
really outstanding. No matter what piece of wire you propose to put up, you
can model its radiation pattern and find out so much more than you can from
the rich folklore surrounding antennas. Try it and see!

Yeah, it's pretty obvious that sending a call faster and more times isn't
an automatic way to improve end-to-end communication -- you could send it a
lot of times at 100 wpm and work nobody. There's a tradeoff between the
time it takes to send your call, and the probability that the other guy
gets it correct. There's an optimal point on this curve.

Most of the players in DX pileups send at a speed under 30 wpm; the DX
station tends to set the pace. After you participate in thousands of
pileups you recognize that the consistently successful DXers have a lot of
skillful strategies for getting their call through, and sending faster is
not one of them. Neither is sending your call more than twice, max.

DXpeditioners who have been on the other end will attest that there's very
little likelihood of a guy sending at 40 or above having his call copied
among the screaming, howling pile.

 For those who care about the relative communications efficacy of various

and analysis, which provides theoretical confirmation of the comments made
above by Jim and earlier by Joe W4TV.
http://physics.princeton.edu/pulsar/K1JT/EME_Florence_2008.pdf
As a side note, we all seen many occasions when FT8 or WSPR could decode

[Elecraft] Why not a KX4?

[Tony Estep]

Actually the KX3 is pretty hard to improve, but the one obvious
consideration is that the internal batteries should be LiPo. Another
possibility would be a different way to generate the oscillator freq to
ensure super-stability; even after the refrigerator procedure mine drifts
-3 or -4 Hz in a WSPR interval, which is right at the ragged edge. I can't
think of any other changes but others may.

I have some LiPo batteries (3S, 11.1V, 3200 mAH) used in electric RC

to a connector that mates with the battery's RC connecton. They start out

Re: [Elecraft] KX3 No meter indication when transmitting digital

[Tony Estep]

Well, I've tracked it down. I don't have a fix yet but at least I have
found out something

For whatever reason, the WSJT software stops putting out audio
unexpectedly. It works for a while, then it doesn't. I don't think it's RF
getting back into the computer, because it happens even when transmitting
to a dummy load at a very low power level of 0.1 watt. Perhaps it's some
problem between the software and my audio driver.  I'm pretty sure I'll get
it fixed.

Thanks again to everyone who responded.

Don, thanks for your comments and the info on your website. Thanks also to
the others who replied.

I am not using AFSK A mode. I never should have said anything about AFSK --
I only mentioned it to explain that the WSPR signal comes from the audio
tone generated by the software.

I have verified that I'm getting audio out of the computer and into the KX3
mic jack. The mic bias is set to off. I'm transmitting into a dummy load,
swr = 1. The meter seems to show the right display (SWR 1 bar, power 2
bars), but when I touch the mic gain knob the display goes blank. I can no
longer get the display showing the ALC, no matter what I do.

Despite all this the KX3 does seem to be transmitting correctly at least
part of the time -- but at other times it does not. If I could figure out
what is happening with the ALC display I think I could get everything going
properly. Any more thoughts?

[Elecraft] KX3 No meter indication when transmitting digital

[Tony Estep]

I have been operating with FT8 and WSPR lately. Both use an audio-generated
digital signal just like any AFSK mode. I tune up my transmitter to show
4-5 bars on ALC. Everything seems to work at first, but after one or two
transmissions the display shows only one bar on the left and one on the
right -- and if I move the Mic Gain, all bars disappear leaving a blank
display. The transmit light stays on but I can't tell if I'm transmitting
any audio or not. What's going on??

thanks,
Tony KT0NY

Yep, gotta have those too, although I use the ones from Muzychenko. To have
a full-house setup you might need VACs, virtual serial ports, and a fan-out
hub. If you use Nap3 with a K3, the LP-bridge is a neat fan-out because it
has a lot of dedicated functionality that Nap3 needs. A few years ago,
having all that stuff running could choke your machine, but nowadays
everything runs smoothly.

It's interesting to note that much of this software hasn't been updated for
years. The Muzychenko VAC is up to date through year-end 2018, but VSPE,
Com0Com, LPB, and VB-Audio are all years old. Luckily it all still works as
far as I know.

That location is where I found all the source files but no matter how much

However, further digging turned up a version of Hub4Com.exe in GitHub.

[Elecraft] Hub4Com

[Tony Estep]

Hi folks,

I'm trying to configure my setup so that one serial port out can talk to
two serial ports in. I downloaded Com0Com, which works fine, but needs
Hub4Com to fan out the output as desired. Fine, I downloaded the Hub4Com
files from SourceForge -- but lo and behold, they are only source files,
along with instructions for building the .exe. But no .exe. What am
I missing?

Thanks to all who know the answer!

Re: [Elecraft] [KX3] QSO of the week (and a re-learned QRP SSB tip)

[Tony Estep]

Well, when I started working QRP I decided never to sign /qrp, but at least
once I wished that I had.

Martti, OH2BH, was on 20 phone and there was a gigantic pile. Finally he
started working by call areas, and when he came to the Zeroes, I finally
got my call through. So far, so good -- but he couldn't quite get my call
right. There were dozens of guys standing by, and Martti stuck with me over
and over, many many tries, until he finally got it. I was too stubborn to
explain that I was running 5 watts, but I could just feel all the guys
wondering why the weak guy was making everyone miserable. I guess that most
QRP ops have a similar story.

I've tried to teach English to students from 19 different countries,

No, that's not right. The radiation pattern and gain of an end-fed halfwave
are little different from a center-fed dipole. The efficiency of an antenna
is not affected by feedpoint location. The end-fed antenna may be harder to
match than a center-fed, but that's a different question. If you have a
proper matching arrangement between the antenna's high impedance and your
feedline, you'll get results that are essentially identical to a standard
doublet. As I mentioned in an earlier post, two minutes with EZNEC will
clarify this.

"Efficiency" refers to the quotient of the antenna's radiation resistance,
divided by ohmic losses. If you have a short piece of wire, its radiation
resistance will be low, but for a half-wave wire it's 73 ohms, no matter
where it's fed.

As a side-note, I worked over 300 countries with a 100-foot wire strung out
my bedroom window (16 feet above the driveway) and running to a tree at the
end of the yard, 40 feet high at the far end. There's a picture of it on my
qrz.com page.

This is 100% correct. Two minutes spent with EZ-NEC will verify that the
radiation pattern of a dipole antenna is more or less independent of the
feedpoint location.The idea that an end-fed antenna is "less efficient" is
wrong. Antenna efficiency is a function of radiation resistance and ohmic
losses, not of feedpoint location.

The power has to go somewhere, and where it goes is into radiation. In the
days before most hams had an antenna simulator program, Cebik was a big
proponent of EFHW and had a nice analysis on his website. He made the
qualitative point that since the impedance at the end is high, there is
little current flowing in the unbalanced feedline at that point; if the
antenna is fed with open-wire line, the return current in the unterminated
leg is small and it's not hard to match. He followed this up with some
actual calculations. Although Mr. Cebik is no longer with us, nowadays
serious hams have antenna programs, so they can do their own analysis. The
role of folklore in antenna design has diminished considerably.

As many have posted here,  it's not hard to do. But even though it's easy

It's true that some find Skimmer advantageous. Bill, W4ZV is a super-op who

clever ideas about how to get the most out of it. But to tell the truth,

useful in a contest but it was of no value in a pileup. If you have a
two-receiver radio and a panadaptor, you can succeed in any pileup.

As all the others have pointed out, the problem here has nothing to do with
LP-Pan. Using NaP3, for example, you can have a birdie-free display of
96Khz on either side, if your sound card is up to it and you set up the
software properly. Having tried both setups extensively, I can assure you
that you will get far superior performance from the combo of LP-Pan and
NaP3 than you will get from a Flex. It also is perfectly possible if you
know what you're doing to run NaP3 and Skimmer simultaneously.

Correct. There are various automated schemes for making sure that the
computer clock is accurate; some have been discussed on this forum in the
past. With Windows 8 and later you can sync manually with government time
standards by clicking on the time in the lower right of the taskbar and
working through the menus.

Yep, those were legendary days. I too made Novice DXCC, shortly after Bill.
He was KN4RID in those days. I worked my 100th right after he got his, but
I stuck my cards in a drawer and didn't send them in for over a decade.
Finally I dug 'em out and got my DXCC certificate, issued under my novice
call, KN0LTB. It's still up on the wall.There was one other novice who did
it, but I can't remember who it was. The bands were open practically 24
hours and 15 meter CW, which was where you had to be as a novice, was
hopping all the time. You could hear scientists from all over using calls
ending in -IGY, standing for international geophysical year. They traveled
to far-flung places to take readings on propagation, weather patterns,
aurora, and anything else they expected to be affected by the record levels
of solar activity. Those were the days of phone patches (no Skype), and 15
phone had a constant flow of patched conversations from scientist phoning
back to the home folks. Even in those days there was SSB activity, mostly
coming from 10 watt phasing exciters. Other popular rigs included the
Viking Ranger and the Heath DX-100. The tube of the day was the 6146. The
older hams who mentored me had home-brew rack-mounted monstrosities,
plug-in coils, something like a pair of 250TH tubes modulated by another
pair of 250THs, power transformer as big as a wastebasket.

That's the truth! A couple of years ago, my K3 would start, everything
seemed to work FB, but when I would turn on my computer the K3 would shut
off. Of course I thought something was wrong in the computer-radio
connection. But what had actually happened is that my power supply had
failed. It worked enough to start the K3 but would shut itself off if the
radio tried to draw significant current. When the computer connected, it
keyed the transmitter just for a few milliseconds, and that was enough to
make the PS click off. I went around in circles for a full day before the
light dawned.

Re: [Elecraft] kt0ny

[Tony Estep]

Hi Bill,

Sorry, I did not notice that your original email referred to the K3 until I
had already sent a reply. I'll be darned if I know why the database isn't
reflecting your transmissions with the K3, since drift is essentially zero
(at least with mine). I assume you're xmting on the right frequency, which
of course you will be if you are decoding signals okay. The only way I know
to check for such a close freq tolerance is to run a WSPR listening program
on another rig. A no-drift signal will be a perfect horizontal line, while
a drifty one will show up as a curve. Maybe you can check with a nearby
ham...?

Do you have the transmit audio gain set right? When WSPR is transmitting,
you should show 4 dots, with the 5th just flickering. Here's a word from
the expert. It refers to PSK, but the same applies to WSPR:

Re: [Elecraft] KX2 on JT65 & JT9 ??

[Tony Estep]

>
>
> Issues with not being able to communicate with JT65 have nothing to do with
> frequency stability

===
Actually, frequency stability is the key issue with JT65. The transmit
frequency can not drift more than about 8 hz during transmission, or the
receiving station will probably not be able to copy. It was this exact
issue that led to the development of the temp compensation scheme for the
KX3. The point of the original question was to determine whether or not the
KX2 needs such a compensation routine, or is stable enough as shipped.

If you run a KX3 without the compensation you may think they can't hear you
when actually the problem is in the small drift in your transmit frequency.
I first discovered this when running WSPR on the KX3 and listening to
myself on a nearby K3. The graphic display of carrier frequency offered by
WSPR made it clear what was happening. My stock KX3 drifted by about 14 Hz
in the first half-minute or so of transmission. Contacts on JT65 were not
impossible, but they were rare, as were WSPR reports.

You can search the archives for many, many posts on this subject, and look
on the Elecraft website for the recommended fix, which involves putting
your KX3 in the fridge, then running a compensation routine while you warm
it up with a heat gun.

Meanwhile, I would be interested to know the answer to the original
question, as I am sure many others would be as well.

A few years ago I bought and tried a Bonito program. At that time the
decoding of nearly every mode was so error-filled as to be useless. I spent
some time comparing it to other digital programs available at the time,
especially that vintage of MixW. Finally I gave up.

Hopefully, things have changed. Commercial-quality software is not as easy
to develop as many enterpreneurially-minded programmers think it is. Bonito
needed to have a lot of turnover in its senior development team. And to be
fair, perhaps it has. Some of the other ham software providers have
upgraded their capabilities with new and more skilled developers, and maybe
the same is true of Bonito. But they left a bad impression with me.

Re: [Elecraft] Sherwood's receiver performance table updated

H. By one estimate, there were more than 2.5 billion smartphones in use
last year (and more today, of course), all with touchscreens. If each
screen is used just for a few minutes a day, the total usage-years is in
the hundreds of millions.

Touchscreen-equipped devices, including phones and tablets, are among the
most widely-used consumer electronic devices of all time. If there is some
undiscovered flaw in the concept of a touchscreen, it hasn't shown up so
far.

True, but even with a high-Q coil a typical base-loaded antenna inevitably

all other system losses. ON4UN's excellent book Low-band DXing has a

I have a terrific wire-beam antenna that rolls up into a package that
weighs only a couple of pounds. However, it requires one rope into a tree
or other type of sky-hook.

It is good for 20, 17, 15, 12 and 10 and is bi-directional. It's a form of
W8JK, but is fed at the end and has series capacitors in each radiator to
make it work over a 2:1 frequency range. I designed it with EZNEC and I'll
send the model to anybody who wants it.

It's fed with window line and requires a balun at the transmitter. It takes
a good tuner to match it, but the Elecraft tuners can do the job.

Anyway, it doesn't meet Wayne's request for a free-standing antenna, but
it's a cool field-day antenna, especially here in the middle of the country
where a bi-directional antenna is a good thing.

Very good, Ed, thanks. I'm sure they use some sort of FEC encoding like
that of the JT software. If I understand that correctly, such a signal can
be decoded if it's a couple of s-units, say 10 db, below the noise level.
So with their ultra-low-noise gadgetry they should be able to hear it for
several million more miles.?

Re: [Elecraft] OT setting your computer to NIST

I think the main point is that for the last several versions of Windows you
haven't needed to, and probably shouldn't, use a 3rd party program to sync
time. You can set up a regular sync with a few clicks from the home screen.
If your machine's clock needs more frequent sync, one way to set the
interval is described in the instructions found here:

 Today I set about to get my new sound card/K3/LP-Pan 2/NAp3/new shack

 I've got the levels set correctly (thanks to Larry) and signals are
apparent
 on the band.  What is perplexing is what I have named The Blob (see
attached
 screen shot).  It is:  on all bands; moves in Free Mode  NaP3) and is
 centered around VFO A marker with about 1/3 of the Blob lower in frequency
 and 2/3 higher than VFO A.  It makes me wonder if there is something in
the
 IF signal from the K3 to LP-Pan. The S-meter on the K3 says it is S3-4 in
 the Blob.  I've searched for a setting in the K3 that I've overlooked but
 nothing.  It is so strange to see a symmetrical shape to the Blog--like it
 is being shaped by a filter. If this is true picture of the spectrum at my
 QTH, then I've got huge problems outside.

 The sound card is a U5 set to 192 Khz.  Computer is a W7 64-bit.  Turning
 the LP-Pan attenuator ON does reduce the amplitude but but does not
 eliminate the Blob.

 I had just completed a noise audit of the QTH  and found some switching
 power supplies that have been fixed with cores. This picture, however, is
 much worse than previously so something has changed.  Just want to rule
out
 a K3/LP-Pan 2 problem.

 I'm going to cross post this on the Elecraft and LP-Pan reflectors.

 Any thoughts and suggestions would be greatly appreciated.

Seems to me that a new design would only be justified if it added some

everything I would want it to do. The only additional feature that would

It used to be that radios were judged on sensitivity and selectivity. Those
measures topped out decades ago, and everyone started looking at dynamic
range, and then close-in dynamic range. At this point, further improvements
in that spec probably aren't going to be noticed in most practical
situations. Maybe the next frontier is in noise reduction, I dunno.

But really, when you talk about the next Elecraft transceiver, the K4 or
whatever, you have to ask what it's gonna have that you haven't already
got. And then after you come up with something (e.g. simultaneous two-band
receive  panadaptor) you have to ask if it really justifies a new design,
or it's just gilding the lily.

So maybe the same thing happened in your case -- you had a combination of

Re: [Elecraft] How Accurate of 50-Ohm Dummy Load for 50 Watt TX Gain Calibration?

[Tony Estep]

Phil,

Your 20-watt dummy load will work with the automated procedure, and it is
the best one because if the SWR is over some threshold you'll get a SWR
too high, calibration failed message.

The 20-watt load is very unlikely to overheat; my 10-watt load did not
overheat, because the 50-watt transmissions are short. However, the sure
way to make it work is to cool it with a sandwich bag filled with crushed
ice.

The automated version only takes a minute or so to do and it only has to be
done once.

If you are unsure, you can follow Wayne's advice and do it manually,
allowing some time to cool in between each band.

[Elecraft] Power supply fan

[Tony Estep]

I run my K3 from a Pyramid ps21kx power supply, a linear supply which has
done a great job for a couple of years. But it has a fan, and when there is
nothing going on in the shack, the fan is audible. So I got a temp control
gadget on eBay for 15 bucks shipped from the U.S. I opened up the power
supply. I opened up the supply, cut the hot lead to the fan and brought out
a little twisted pair to an R/C connector so I could control the fan with
the temp gizmo. I stuck the sensor next to one of the power transistors
with some picture-mounting gum. Now all is quiet until I transmit. Then it
kicks on and stays on (you can set both in and out temperatures), so
everything stays nice and cool as well as nice and quiet. If you're looking
for a good power source for your K3, I recommend the Pyramid, and I also
recommend this simple mod.

Re: [Elecraft] AUTOINF Auto 1 Anomaly

[Tony Estep]

Rick, obviously if it worked before, and it's working now, your hookup can
not be the problem and never could have been.

One possible cause: The communication chips that send and receive this sort
of message have a little bit of on-board memory, which is used as a ring
buffer. Sometimes, due to a static blip or an accident of timing or
whatever, these buffers can get hosed. A hardware reboot will fix it. This
might have been what happened in your case; the computer and the steppir
chips were working okay and could talk to each other, but the k3 had gotten
into a frozen state. This sort of thing can also be caused by rf in the
shack. Anyway, you're up and going, so all is well.

  It does come down to the fact that RS-232 buss definitions do not allow

 Check your settings for the SteppIR application.

across a long-winded qso at about 85 wpm and I couldn't copy a doggone

enough, the CW reader started revealing words and then sentences and
paragraphs. It missed words, but there was plenty enough copy to follow the
whole conversation. I also tried my software CW reader; it got nothing.

If you think about it you can see that a CW reader has lots of challenges,
way more than an FSK reader. So it looks to me as if that little processor
inside the K3 is doing pretty well. Maybe it could be better, but it seems
usable as is. And really, the average qso takes place at more like 25,
which shouldn't present a problem for plain old ear copy.

Yeah, actually I have been working on an Artificial Intelligence add-on
that checks the band and the cluster to see if the guy you are calling is
working split. Then if you try to call him on his frequency, your
transmitter does not send anything, but your side-tone starts sending UP
U-P UPUP UP UP. This cannot be turned off until the dx has
completed 2 QSOs, so the penalty for messing up serves as a disincentive to
do it again. I am planning to seek Kickstarter funding.

My question is this: should I sell 'em at cost as an open-source project,
or sell it as a commercial product? Or how about this -- I could make a
package price by the dozen, so that disgusted DXers could buy them in bulk
and send them as gifts to the nitwits they hear in the piles.

 There are a few K3's here too :-)

Re: [Elecraft] Flex VS K3

 ...investing the serious amount of money a Flex gets and then running it

One of the various things that conspired to kill the previous version of
the Flex software was the proliferation of cloud-related software on newer
machines. A Microsoft Skydrive, or a Google update program, or one of a
large number of other stuff, would periodically issue an interrupt that
would take the CPU's attention away from the Flex data stream, introducing
latency and/or crashes.  The first design was a recipe for obsolescence.

Besides, if you wanted PSDR, a K3 with LP-Pan and NaP3 has a superset of
the capabilities of a Flex 5000, and none of the endless series of  bugs
that plagued the Flex version of PSDR.

The new Flex stuff brings the data path inside the radio, so that the
dependency on the OS is reduced, and it probably works okay if you want to
try to operate your station with the mouse. But at least IMHO, a DXer
working split in a big CW pile without knobs is at an overwhelming
disadvantage.

 Unfortunately, so-called neutrality means that one company, Netflix, can
corner it without paying for it. Netflix accounts for up to 35% of internet
traffic, and is really the one and only beneficiary of this ruling.
Everybody else is subsidizing them. In any event, I'm just glad I'm not a
regulator.

I realize this discussion is kinda pointless and not worth prolonging, but
nonetheless... it seems that if both speakers go in and out at the same
time, the resulting sound waves would be in phase; whereas if one speaker
goes out when the other goes in, the sound waves would be considered to be
out of phase (i.e. the compressions and the rarefactions would cancel). So
at least in the case of a pair of speakers sitting side-by-side and fed
with the same audio, switching the so-called polarity of one would indeed
change its phase relative to the other by 180 deg.
