[Elecraft] SOTA

[Dan Presley]

After reading Wayne’s great post I couldn’t help but send this. A group of us 
(4 hams) hiked up to a forest service lookout tower in the Oregon cascades and 
operated. It’s brief but you get the idea. I’m running the KX2 and AX1 on 20. 
Long steep uphill hike-Clear Lake Butte near Timothy Lake,if you know the area. 
About 4500’ actually going down was harder on the 68 year old knees than up!

Re: [Elecraft] Peaks, parks, and prayers: CW & SSB islands in a digital sea

[Gwen Patton]

I use an older Chromebook, Dave. I removed Chrome OS and replaced it with
GalliumOS, a Linux distro for Chromebooks. You can get an older model
Chromebook for really cheap these days, and that gives you a display,
battery, keyboard, trackpad, processor, and multiple digital mode apps, all
nicely self-contained. And you can use it for other things, too. The only
thing you'll have to add is a soundcard dongle, because the incredibly
stupid audio system in most Chromebooks is too braindead to work on digital
ham apps. Even a really fancy one will cost you only around $30, and there
are far cheaper ones that will do. That's the dongle, not the Chromebook. I
paid about $120 for this one about 5 years ago. I replaced the Chromebook
with a better, faster one with more RAM, a microSD slot that doesn't stick
half an inch out of the side of the machine, and USB-C.

I've got WSJT-X and JS8Call on it already, some logging programs, and
things like Echolink. The MDS Phaser I use it with is set up for 40m FT8
and JS8, but I can switch the JS8 to any frequency I want and run other
modes if I feel like it. Perhaps some Slow-Scan images, who knows?

I've seen some very fancy Raspberry Pi builds for it, though, if you want
to go that route. You'd have to add a display, keyboard, mouse, and power.
OR you can set it up headless and run it with a tablet or even your phone
over a remote access program like VNC. But that adds even more expense
unless you already have the tablet or phone. I'd still recommend a wireless
keyboard, though. Typing on a phone or tablet can be a pain, and there's
some really nice Bluetooth keyboards out there now, even folding ones you
can stow really easily.

I really like the Phaser. It's more challenging on FT8 than a full QRO
station, of course, and it's VERY packable. It makes a fantastic field rig
for working from parks, or probably for summit operation, though I don't do
that. There's few summits you can take a wheelchair to. hi hi

[Elecraft] Elecraft CW Net Report

[kevinr]

Good Evening,

The chilly, wet weather caused my hands to stiffen up.  I kept wishing 
for zerk fittings on each knuckle.  Spring changes to summer very slowly 
in Oregon; sometimes we have to get out and push.  The hot temperatures 
reports from the Midwest helped a little.


Conditions were much like last week and the week before.  We do have a 
sunspot which is moving into a good position.  It is also unstable.  A 
CME would be nice.  More sunspots for Field Day would be even better.

Re: [Elecraft] Zero-beating a KX1

[lmarion]

I installed a N0SS (much missed silent key)
zero beat indicator, works excellent. I put one in my K1 and K2 also.

Subject: [Elecraft] Zero-beating a KX1

I recently obtained a KX1, which I am delighted with it. However, I haven’t 
found a way to zero-beat a signal other than to go to the menu to listen to 
the sidetone, memorize it and then return to the VFO. I found a faster way 
to to that, but it is still just memorizing and going back and forth. Is 
there a better way to zero-beat? For those of us who don’t have perfect 
pitch? :-)

Re: [Elecraft] Peaks, parks, and prayers: CW & SSB islands in a digital sea

[David Gilbert]

Thanks to Ray and Gwen for the tip, and that indeed looks like a really
nice low cost way to go.  But I already have a KX2 and I would still need
to bring along a notebook or small laptop computer.  I could certainly
homebrew a combined unit consisting of the MDS Phasor, a Raspberry Pi, and
a 12 volt display ... total cost would probably be less than $200.  I just
think that a self-contained unit would be inherently smaller, and probably
a good seller if Elecraft ever was inclined to offer one, especially if it
provided multiple bands.

Thank you.  I'd be really disappointed if the keying waveform for the K4
was made adjustable.  I consider the fact that it is not adjustable on my
K3 to be one of its best features.

Hi Pete,

Probably not. We've always been very careful to ensure our rigs have an 
exceptional clean, click-free CW signal. (Third-party testing bears this out.) 
Minimizing the bandwidth requires a very specific rise/fall time and a 
hand-crafted sigmoidal shaping function in DSP.

Colonel Sanders closely guards his fried chick recipe, Mrs. Fields won't reveal 
what's in her chocolate-chip cookies, and only selected firmware monks--sworn 
to secrecy--are privy to Elecraft's keying envelope coefficients :)

Re: [Elecraft] OT Bluetooth Serial adapters

If it's one of the Logitech "Unifying" dongles, you can get them on Amazon
from various sources:
https://www.amazon.com/logitech-dongle-replacement/s?k=logitech+dongle+replacement
One dongle can support up to 6 Logitech devices on a single computer using
these.

Microsoft dongles, however, are keyed specifically to the keyboard and/or
mouse they were sold with, and you pretty much have to buy a new set if the
dongle goes missing. They can't recode a new dongle.

I really hope the answer is "No."  Rise/Fall times and waveshape of the

[Elecraft] Using a SDRPlay RSPduo as a K3 Panadapter for Remote Operations

[Barry Baines via Elecraft]

My Elecraft K3-KPA500-KAT500-P3 is remotely operated through the K3/IO-mini and 
Remote Rig from my station in Southeast Georgia,  The system works well but I 
don’t have remote access to the P3.  

It finally dawned on me recently that I could potentially use a SDRPlay RSPduo 
SDR receiver that I currently own as a panadapter and then use VNC Viewer to 
connect to the shack PC to view the panadapter.

As the P3  has an IF output,  I plan to connect that output to one of the 
RSPduo’s SMA inputs.  The PC that is at the shack is already setup for remote 
access, so I could simply install SDRuno and run the software to see the 
Panadapter display. That leaves the issue of how to obtain K3 frequency and 
mode information (presumably using OmniRig to feed data to SDRuno) for managing 
the SDRduo’s  display of the K3’s frequency as the center frequency.  I presume 
that the SDR software would be set to the IF frequency from the K3 (8.215 MHz).

Currently, the K3 serial port is connected to the Remote Rig for remote 
control.  However, it is possible to run a serial cable from a PC ComPort to 
the back of the P3.  So if that connection is made, will it be connected 
serially to the K3 as well as to the P3?  If not:

1.  Is a serial port y-adapter between the K3 serial connection and the Remote 
Rig connection to add a PC serial port connection acceptable under the 
presumption that the PC won’t be sending commands to the K3 but only receiving 
data from the K3?

2.  Do I use a PC program to provide data from the K3 to both the Remote Rig 
Com Port and to SDRuno?  In this case, presumably OmnRig would be accessing a 
virtual serial port (VSPE) rather than a physical serial port.  I understand 
that LP-Bridge is not compatible with SDRuno so is there a similar ‘repeater’ 
software for distributing serial information to various destinations?

3. Am I better off to use something like Win4KSuite as the interface between 
the K3 and RSPduo?  This apparently eliminates the need for OmniRig and 
provides integration with SDRduo.  It also appears that this software supports 
the K3/IO-mini, so does that mean the “Mini” is connected to a PC ComPort and 
the interconnection is made through Win4KSuite?  One issue that I see with this 
approach is that if there is an issue with the PC, I will lose my K3-K3/IO 
connection as well.

4.  Are there other software packages that I should consider?

If anyone is using a K3/IO remote connection as well as using a PC in the shack 
as a Panadapter display through a SDR receiver, I’d appreciate your thoughts on 
this.  I’m  planning to head back to SE Georgia at the end of this week 
(Thursday/Friday) and would like to set this up while I’m there before 
returning to Texas later in the month.


Thanks,

Barry Baines, WD4ASW
Keller, TX

[Elecraft] Zero-beating a KX1

[Andy Durbin]

Ref the linked article - "you slowly tune the received signal until it reaches 
the magic tone that means "zero-beat". Usually, this is the same tone as your 
CW sidetone, 500-800 Hz, depending on your rig. You need a good ear for pitch."

Has everyone forgotten what to "zero beat" means or is it simply that the term 
has become so abused that it means something different now.   Zero beat used to 
mean to shift the frequency of one signal relative to the frequency of another 
signal until the audible beat frequency reduced to zero.   In those olden days, 
using an AM receiver to receive CW, the technique I remember was to set the BFO 
(Beat frequency Oscillator) to zero offset, tune the signal for zero beat, then 
adjust the BFO offset for desired pitch.

How can tuning a single frequency to desired pitch be zero beating.  There is 
no beat frequency to zero.

Andy, k3wyc

Here in Maine we have many opportunities for mountain trekking but you can

Maybe you can answer my question, then.

A while ago I came into possession of a Dell "wireless" mouse and
keyboard set (Logitec ?) for a desktop computer where I elected to use
wired accessories.  The mouse and the dongle are now being used with a
Surface.  That leaves the keyboard "stranded".  Are "replacement"

is the keyboard usable only with that dongle?

Re: [Elecraft] K3S dead after attempted firmware update - Fixed

[K8TE]

Having worked in IT, I can tell you professional IT organizations test
patches before deploying them.

Regarding Windows 10 Home use, you can delay patches now (a recent update).

Finally, for a long time, you have been able to prevent Windows 10 from
updating drivers which can lead to COM port number changes: 
https://www.minitool.com/news/disable-automatic-driver-updates-win-10-009.html.

Windows and our computers are just like any tool or even a piece of radio
gear.  it behooves us to learn how to use those tools and to stay current
with updates to them.  These tools are more complex than hammers and just as
dangerous in un-trained/educated hands.

There is plenty of information (much of it correct) available with a quick
Google search.  Before I spend a weekend or just a day contesting, I always
check for Windows Updates.  If one is available, I download and install it
on ONE computer, test it, and if acceptable, do the same on my other
computers.  I also check all of my antennas and the rest of my station's
systems.  They are all tools of the "trade."

You captured the essence and feeling of mountain top radio. I love it and never 
cease to get a kick out of what you describe around the moment of the first 
contact (which includes a mountain of anticipation as to whether there will be 
a first contact).

Of my almost 250 mountain top activations and 40 or 50 NPOTA activations, I had 
either my KX3 or KX2 and neither have ever let me down. My antennas have 
failed, my coax has failed and my ability to spot (I’m SSB so not RBN for me) 
has in a hollowing gale atop a cold mountain had be retreat and fail but never 
the radio.

Thanks Wayne (and your team) for all you have done for the /P brigade.

Re: [Elecraft] [OT] Birds and DX

[RICHARD Martin]

You can purchase light weight telescoping fiberglass poles (about 25') with
a kite that looks like a bird of prey.  The kite bobs, swirls and dives.
Quite an entertaining display.

They work quite well keeping the birds and squirrels away from our fruit
trees.  They are also popular along Sunset Drive in Pacific Grove to deal
with the seagulls.

Re: [Elecraft] Zero-beating a KX1

[Fred Jensen]

I believe the only way is to match the pitch to the sidetone pitch, 
Kelly.  At least I never found another way during all the time I had my 
KX1.  The KX1 is a really nifty little package, no?  I finally sold mine 
when injuries from adventures in my 20's coupled with the accumulated 
birthdays began to limit what I could do in the field.  I use my K2, 
battery, and solar charger now since I never get very far from the 
truck.  I also found that zero beat was overrated.  "Close enough" seems 
to be "good enough."

[Elecraft] K3 loses transmit power

[Charles]

I was using the K3 at low power on PSK, and suddenly had no transmit power.  
Zip.  Receive worked fine.  All modes/bands/attempted power levels gave no 
power out.  The rig was not in test mode, Config showed Tx inh=off, and 
KXV3=nor.  Unfortunately the K3 is remote--about 250 miles, so an in person 
look will take a drive.  Power output is monitored by an Alpha 9500 at the 
remote site.  The lack of power was confirmed by a second user with his K3/0 
mini/Remote Rig set.  I saw one posting where a diode on the Rf  board had 
blown:  this would be nice!  Does anyone have any further ideas??

Thanks, Chuck, N8CL

Re: [Elecraft] Zero-beating a KX1

Kelly,

If you do not have perfect pitch, then what you are doing is one way. 
Another way would be to build a tone generator for your preferred 
sidetone pitch and use that.

Re: [Elecraft] Peaks, parks, and prayers: CW & SSB islands in a digital sea

[David Gilbert]

I suggested this about a year ago and got mostly dismissive replies from
the group, but I still think that a small, dedicated FT8 rig (and similar
modes) would be an attractive offering.  Something the size of a KX2 or
maybe just a little larger, with a modest display and separate
processors/memory for the rig and the digital modes.  It's entirely
possible to run FT8 from a Raspberry Pi and an inexpensive display, but an
all-in-one rig would be so much more practical.  The rig portion itself
could be MUCH simpler (and therefore less expensive) than a KX2.

Re: [Elecraft] K3S dead after attempted firmware update - Fixed

[Ian Kahn, NV4C]

Actually, this is one of the worst ways Microsoft could handle updates. 
I work in information security for a hospital. I shudder to think what 
would happen if patching reset our life-saving critical clinical systems 
to all the default settings every month. Our infrastructure team would 
spend all their time putting out fires.


While the impact for end-users isn't as life-or-death, it is still 
unreasonable to think that every time our systems get patched/updated, 
we have to reconfigure them. This is amplified by the fact that 
Microsoft no longer gives the home user any advance notice of when their 
system will be patched, nor way to disable automated patching.

To my surprise the K3S then started normally & with the new PC I was

download a new copy of the Utility program & the latest firmware. This

So, what was wrong & why did it not work before?

[Elecraft] KX3 For Sale

[David Kuechenmeister]

I've decided to part with my Kx3, in favor of the Kx1 for portable 
operations. Before I put this up on QRZ, I thought I'd offer it for sale 
here.


It works very well. It's just that I usually find myself on 30 or 40 
meter CW and it's far to capable a rig to just use 10% of the features. 
Besides, I want a new antenna and this will get me there. Yes, it's an 
expensive antenna!


Elecraft KX3 with all the built in options,
- KXFL3 Roofing Filter
- KXAT3 Antenna Tuner
- KXBC3 NiMH Charger/RT Clock
- KX3-2M Transverter

And these accessories,
- MH3 Hand Mic
- KXPD3 Paddle
- KX3-PCKT Cable Kit

Plus the KE7X book, "The Elecraft KX3-Portable", as well as printed 
owner's and assembly manuals.


Excellent condition.
Price is $1400.00, includes ground shipping within CONUS
Pictures available on request.

Payment by PayPal or USPS money order.

Thanks for your interest,

vy 73,

Dave, N4KD

[Elecraft] Zero-beating a KX1

[Kelly Breed]

I recently obtained a KX1, which I am delighted with it. However, I haven’t 
found a way to zero-beat a signal other than to go to the menu to listen to the 
sidetone, memorize it and then return to the VFO. I found a faster way to to 
that, but it is still just memorizing and going back and forth. Is there a 
better way to zero-beat? For those of us who don’t have perfect pitch? :-)

Re: [Elecraft] K3S dead after attempted firmware update - Fixed

[Bob McGraw K4TAX]

Since Microsoft does not know of every piece of software, on every 
Windows computer in the world, for simplicity, very often a Windows 
update will set values to DEFAULT values.  Therefore, it is necessary 
for the user to set certain parameters to their preferred values after 
an update.    I view that this is no fault of Windows, it is just the 
way they handle updates.    Unless one is very familiar with the 
in-depth operation of Windows,  it is wise for anyone to make notes of 
values, locations and they way one access certain application settings.

Hi Buck

What did I do to fix it?

Well I left the K3S disconnected for an hour or so while I read the

supply & use a different PC & a different USB cable.

To my surprise the K3S then started normally & with the new PC I was

download a new copy of the Utility program & the latest firmware. This
connected immediately to the K3S.

So, what was wrong & why did it not work before?

I have absolutely no idea!

Re: [Elecraft] OT Bluetooth Serial adapters

[Gwen Patton]

Dang, I misread your post, and didn't see the "serial" part.

I don't use BLUETOOTH serial with my KX3, because there's no way to get the
pairing code. I DO use a 2.4GHz dedicated RF dongle to a wireless keyboard,
that I plug into my PX3. Since it's dedicated, it doesn't need to "pair" to
the device, it's just always connected when active. I tried using wired
keyboards to use the CW/PSK/RTTY feature of the PX3, but I always got stray
RF in the cable, causing unpredictable results, including extra characters
in the keyboard buffer that kept the transmit going past when I'd stopped,
sometimes indefinitely, since the new output stuffed more garbage into the
keyboard buffer. The dedicated wireless doesn't suffer from this, so I can
use the keyboard without problems. (And YES, I did try toroids, chokes,
etc. No help.)

Re: [Elecraft] OT Bluetooth Serial adapters

[Gwen Patton]

I have a small Bluetooth adapter that I sometimes use. It's about the size
of a silver dollar, with a short wire with a 3.5mm TRS plug on it. Since I
routinely wear a Bluetooth headset, I can plug the adapter into any 3.5mm
TRS output and pair to the transmitter with my headphones, and don't have
to deal with yet more wires just for my headphones. The only reason I don't
do it more often is that my headphones will only reliably pair with one
device at a time. There IS a way to pair it to two devices, but I've found
it unreliable and don't use it.

It's a help when I have want to connect to a bluetooth speaker, but don't
want to use the AUX cable. If I change devices, I can move the transmitter
to the new device. The only issue is that it's just as easy to use a jumper
cable to the AUX socket on the speaker, and the wire doesn't really cause
that much of a problem.. So it's almost more trouble than it's worth. But
it DOES work, and works just as well on my KX3 as on anything else.

Oh, please, please bring back the CW note of the Drake 4-line!

Bob McGraw K4TAX wrote on 6/6/2020 10:59 PM:
There are actually 2 time elements involved.  First is the time 
between key closure and the amp key command.  This is approximately 
3ms of processing time inside the radio.  The second is amp key 
command to RF generation out of the radio.  This is the 5ms between 
amp key command and RF generation.    These are summed together to get 
the total time from Key closure to  RF generation of about 8ms.


One other company to which I'm very familiar,  specs their radio as 15 
ms RF delay.  What is not disclosed is a breakdown of this 15ms,  that 
7 ms of the total time occurs from key closure to amp key command, 
thus leaving 8ms from amp key command to RF generation.  This requires 
the amp to switch in 7ms or less.   A mechanical relay is really being 
pushed to accomplish this fact. This 15ms delay is not user 
adjustable. And the CW rise and fall time is 5ms.  A bit fast for a 
really clean signal.    Another model of the brand offers and 
adjustable CW rise and fall time adjustable between 3 - 10 ms.  The 
longer time makes for a much cleaner CW signal.  Again the delay from 
key closure to RF generation is in the order of 15ms.


Older amp designs, typically those that do not clearly provide QSK 
identification or mode, are typically not suitable for QSK operation. 
Thus switching one of these amps at the faster speeds will most likely 
cause hot switching, resulting in key clicks and eventually relay 
failure.


I've found the K3S and KPA500 to produce some of the cleanest CW 
signals on the bands.   Timing is the secret and the design team at 
Elecraft have focused heavily on this aspect of these products.

If you think hams are fanatics about ham radio things like DX or
contesting, birders exhibit the same reaction about messing with their
birds.  The wife of one of my ham colleagues is very much a birder and
that leads to do some interesting interaction.  He put all of his

I had a "fake owl" (from the HRO catalog)  mounted on the peak of the
A-frame roof over the doorway of my former "House of 13 Antennas".  The
crows loved to dive-bomb and perch on it while ignoring all the other
places provided by the antennas and left us plenty of "souvenirs" as a
token of their affection..

The best way I've found to calibrate the K3 reference oscillator is to use the 
500 Hz and 600 Hz audio tones transmitted by WWV. I put the line out audio 
through a sound card and look at it with SpectrumLab. Tune in WWV in USB or 
LSB mode and tweak the reference trim until the tones are correct when you 
switch sidebands with the dial at precisely XX.000 000 MHz. I've found that 
you can't get precise agreement between sidebands, probably because of 
quantization limits in the synthesizer, but it will certainly be less than a 
couple of Hertz. This is plenty accurate for amateur (or probably any other 
kind) of service.

I use WWV with the radio in CW mode and CWT on, tune close to WWV and press 
SPOT.    If it settles on the WWV frequency that's good.  If it is off a few 
Hz, then I tweak the REF CAL up or down a few Hz until I get the accuracy I 
wish by repeating the process several times.  Still I find +/- 1 Hz is about 
it, even with the high stability TXCO and very adequate warm-up time of about 
2 hrs.


If one needs something more accurate, then Don is correct, test equipment is 
the way to go.  And expect to spend big bucks for good quality equipment that 
IS traceable to NIST.   If the NIST document or calibration is more than 1 
year old, the results will be questionable.


I wrote an article which was published in QST, Sept 2015.   It deals with 
"Transmit and Receive On Frequency".  It shows that digital readouts are just 
that, readouts,  and they are not frequency determining or measuring 
circuits.    And when it is accurate on one band it may not have the same 
accuracy on another band.

My frequency counter is good to 10 exp-9 which equates to +/-0.1 Hz at the 
TCXO frequency, so the WWV method provides as good or better accuracy, even 
considering the doppler shift possibility.


The main problem is chasing the beat note down to a stable solid note. You 
usually can't truly get there, but you can get close enough that you hear 
about 10 or 20 seconds between peaks. Close enough for me.


It can be quite expensive to obtain stability better than the K3S in an 
analog oscillator.  My HP8640B signal generator will do that, but it takes 
at least a 3 hour warmup before it becomes stable.  Yes, all the internal 
enclosures in my '8640 have covers with all the screws installed - that 
helps.  OK, that is 'old iron', but I am not going to spend several $10,000 
for something better.  I have better things to do with my money, and no 
longer have access to modern lab quality equipment to achieve that kind of 
stability.


We have a ham band transceiver - not a precision lab instrument. As long as 
we can stay inside our ham bands, that is all that matters to me.  I would 
not put a carrier exactly on 7,000.00 kHz with any transceiver.

[Elecraft] Peaks, parks, and prayers: CW & SSB islands in a digital sea

[Wayne Burdick]

Every day, hams worldwide, young and old, summit mountains and hills carrying 
the lightest possible load. They earn every calorie burned, and are rewarded 
with vistas most people never see. Like all adventurers, they proudly display 
nature's merit badges: scrapes, bruises, and stings. 

And then they go back for more. The number of peaks "bagged" by some operators 
is staggering, as is their level of fitness and endurance.

In addition to those formally pursuing peaks (via SOTA, or Summits on the Air), 
there are many others who operate casually from hiking trails and parks. Some 
operate while they walk (pedestrian mobile, HT-style or HFpack). Some operate 
bicycle-mobile.

I'm writing this out of admiration for, and in solidarity with, all of those 
who commune equally with nature and the ionosphere.

* * *

There's one thing these hams have in common.

Upon arriving at their destination -- tired, sweaty, hungry, elated, or some 
combination of these -- they hope to make a few QSOs. To experience a synthesis 
of the outdoors and the radio art.

But it isn't always easy.

While many hams have transitioned to computer-based digital modes such as FT8, 
others have not. This includes ultralight travelers, as well as those who seek 
the satisfaction of home-building simple gear and putting it on the air. 

For portable operators in particular, simplicity and pragmatics often dictate 
the use of CW and SSB. It may not be desirable or even possible to lug a laptop 
in your pack, find a place to set it up, and attach its myriad cables. You 
might struggle to see a washed-out LCD screen in direct sunlight. High winds 
might capture an open laptop and sweep your gear away. 

Many, instead, choose traditional modes. These allow for small, integrated gear 
that can often be hand-held. And there's the bonus of immediacy such modes 
offer, without mediation, without constraints on duration or content.

To put yourself in their shoes, imagine that you just trekked several miles, 
much of it uphill. To accommodate the need for food, water, clothing, and 
safety gear, you've brought a minimum amount of radio equipment. It might be a 
3-ounce CW QRP radio; an HF-VHF-UHF portable, an all-band/all-mode HF HT (like 
a KX2), or your latest home-brew transceiver.

When you arrive at your peak, you survey the spot for a suitable operating 
position. It might be a large, flat rock; a patch of ground not infested with 
ants and spiders; or a shady spot with a downslope in a favored direction. You 
might climb a tree. Shelter beneath a ridge. Or dangle your legs and antenna 
from a cliff.

Speaking of which, deployment of antennas presents another challenge. You could 
spin-cast or toss a wire, hoping for a good landing, without snags. You might 
wedge the feet of a tripod into rocks, then attach a small magnetic loop. Or 
you might use a simple telescoping whip. 

All that effort. Now it's time to turn on the radio. 

Virtually every time I've gone on such an outing, I've made contacts. At times 
I've been lucky. Maybe it's operating experience: knowing who to call.  

But sometimes there's no one around on CW or SSB. Is it propagation? Or is 
everyone swimming in the digital sea, not paying attention to you, on your 
remote island? 

You can spot yourself on RBN (reverse beacon network), or prearrange skeds. But 
what many of us hope for is that burst of contacts. Feeling like a rare DX 
station. Feeling that slap-on-the-back-at-a-distance that says: 

"We hear you."

* * *

You can, of course, partake of this experience yourself.

Whether you do or not, though: Please consider listening for those who do. 
Formal activations are announced in advance. See for example:

   https://www.sota.org.uk/

The band segments used are very small, or even a single frequency, making it 
easy to monitor them while you engage in other activity around the shack or on 
the air. You can use SOTA spotting websites, or just keep a receiver on one of 
the watering holes. (The Elecraft K3/K3S/KX2/KX3 make this easy, with built-in 
scanning. You can set the rig up for either muted or live audio scans, the 
latter making it easier to hear weak signals when they pop up.)

One final thought. In this pandemic era, some of us have had more time to get 
on the air, and some of us have had more chance to get outside.

Let's do both. At the same time.

73,
Wayne

Chris,

Remove the red ones from C21 and C23, and put the yellow ones in those
positions.  The red ones go at C44 and C46.
That is indicated in the errata pages.  You should read the errata and
mark the changes in the manual.
Yes, I realize that the manual states that C21 and C23 have a red
marking, but that was long ago before the trimmers were changed. Now the
errata is the only correct source of the latest information.

Do you have the correct inductors at L12 and L13 - they should have a

Are the capacitors C43 and C47 actually 33 pF (marked either "33" or

Are capacitors C42 and C48 actually 330 pF (marked "331").

Are you able to tune 12 meters?  The trimmers at C44 and C46 should have

By any chance did your first computer receive any updates from Microsoft

To my surprise the K3S then started normally & with the new PC I was able to

So, what was wrong & why did it not work before?

Chris,

The LoP message indicates that there is not enough power to tune the KAT2.

As your first troubleshooting test, unplug the KAT2 (both cables) and
try again - connect a dummy load to the lower BNC jack on the base K2.

See if you get power output on 10 meters.  If not, look carefully at the
bandpass filter for 10/12 meters.

If the bandpass filter is OK, then you will have to do Transmit Signal
Tracing.  Build the RF Probe if you have not already done that and turn

Re: [Elecraft] K2 showing Lo P on 10 meters, and no transmit power.

[Christophe GIBERT]

Hi Don, I've made some troubleshooting today.

Without the KAT2, I've got no power on 10 meters.

Visually all is good at bandpass filter for 10/12 meters. I've remade some 
joints but the problem remains.

With the troubleshooting of page 14, here are the values :

U10 pin 4 : 0.012 Vrms
U9 pin 6 : 0.293 Vrms
W6 : 0 or near 0 V
So in S1 anode : 0 V or near... It seems to incriminate the bandpass filter or 
am I wrong ?

Please tell ...

Thanks a lot.

Objet : Re: [Elecraft] K2 showing Lo P on 10 meters, and no transmit power.

Chris,

The LoP message indicates that there is not enough power to tune the KAT2.

As your first troubleshooting test, unplug the KAT2 (both cables) and
try again - connect a dummy load to the lower BNC jack on the base K2.

See if you get power output on 10 meters.  If not, look carefully at the
bandpass filter for 10/12 meters.

If the bandpass filter is OK, then you will have to do Transmit Signal
Tracing.  Build the RF Probe if you have not already done that and turn
to the Troubleshooting appendix in the manual.  Do the troubleshooting
on page 14.  Use 10 meters instead of 40 meters, and tell me at which
point the RF voltage is significantly (more than 10%) less than the
expected voltage.

Contact the Audobon Society to see if you can have a nest for a bird of
prey (falcon perhaps).  Hopefully, it is one that will like crows as
well...

Some things to consider:

1.  From what I can tell, most of these devices are designed to be plugged into 
a computer.
a.  Presumably you’d attach the adapter to the RS232 port of the D710.  So the 
first question is how you’d power it.  Power would likely have to come from a 
USB charger.
b.  How do you configure it?  Would you attach it to a computer, configure the 
settings and would the settings be retained by the device (not the computer) 
when the device is powered down and removed to be reconnected to the D710?

2.  The next question is configuring the Android:
a.  What software are you intending to use on the Android?  Does it use a com 
port?
b.  Is there a way to configure a bluetooth connection as being a com port?
c.  Would the software recognize a bluetooth input as  a comport?

I don’t have experience with these devices. My suggestion is to first look at 
the Android and the software you intend to use with the D710 to determine 
whether it has the capability to recognize a CompPort connection via Bluetooth. 
 Second, when looking at these devices, look at their compatibility in terms of 
being connected to a non-PC.


Hope this helps,

I had a similar problem with one of my early mag loop attempts about 20 
years ago. If your loop is a single turn type you could arrange for the 
tuning cap to be at the bottom with the coupling loop at the top. That 
puts the voltage-neutral point where the birds will perch, and they will 
have no effect on the tuning.


The birds don't bother my two-turn mag loop (pix on my QRZ page) at all 
these days because they prefer to perch on the LPDA on the main tower.

I see there are many implementations but I'm not sure if it is worthy of

[Elecraft] K3S dead after attempted firmware update - Fixed

[Ray Spreadbury via Elecraft]

Hi Buck

What did I do to fix it?

Well I left the K3S disconnected for an hour or so while I read the "trouble
shooting" sections in the owners manuals. I decided to change the power
supply & use a different PC & a different USB cable.

To my surprise the K3S then started normally & with the new PC I was able to
download a new copy of the Utility program & the latest firmware. This
connected immediately to the K3S.

So, what was wrong & why did it not work before?

I have absolutely no idea!

Owls don't work unless (maybe) you can mechanize it so that the wings 
flap and it hoots.


I have a roof with pigeon issues, and the only thing that works is to 
make the surface unattractive to them. If there is some way you could 
attach spikes to the top surfaces... maybe superglue broken glass to it? 
Or wrap it with fiberglass insulation, or use that plastic stuff used to 
protect kids from the supports of a swing set to make it too fat for 
them to want to sit on.


The only thing that works (other than birdshot) is to make the surface 
unattractive.

airport.  There seems to be just as much bird excrement on these aircraft and 
on those with no owls.

[Elecraft] [OT] Birds and DX

[Andy Durbin]

I use a home brew mag loop on 30 m band and work into Asia most mornings with 
it.  The loop tunes to a near perfect match (1.00:1 SWR) but becomes instantly 
detuned when a dove perches on top of it.  SWR jumps instantly to > 3.0:1 and 
trips my High SWR monitor.The birds look stupid but they are smart enough 
not to straddle the loop opening.   I imagine full loop voltage between their 
legs would de-tune them a bit but they just perch one side or the other.

Damn dove nearly cost me a QSO with JD1 this morning and that was new DX for 30 
m.   I tail ended with FT8, he came back, I started to send my report, High SWR 
trip, run to back door to chase the dove away, and got back before JD1 had 
given up on me.

So how to keep birds of a mag loop without lowing the Q?

[Elecraft] KX3 KXPA100 problem

[Mike Kasrich]

For some reason the combo seems to be stuck in "tune" mode. I've tried 
restarting everything. Hitting tune on the rig and amp to get it to 
cycle but nothing seems to be working. What am I overlooking?

Re: [Elecraft] K3(s) main oscillator calibration

[Randy Farmer]

The best way I've found to calibrate the K3 reference oscillator is to 
use the 500 Hz and 600 Hz audio tones transmitted by WWV. I put the line 
out audio through a sound card and look at it with SpectrumLab. Tune in 
WWV in USB or LSB mode and tweak the reference trim until the tones are 
correct when you switch sidebands with the dial at precisely XX.000 000 
MHz. I've found that you can't get precise agreement between sidebands, 
probably because of quantization limits in the synthesizer, but it will 
certainly be less than a couple of Hertz. This is plenty accurate for 
amateur (or probably any other kind) of service.

From my take, it is "ham radio" therefore +/-1 Hz. should be good

+/-1 count as I see it.   I can keep mine +/-2 or 3 Hz on most bands.


I use WWV with the radio in CW mode and CWT on, tune close to WWV and 
press SPOT.    If it settles on the WWV frequency that's good.  If it 
is off a few Hz, then I tweak the REF CAL up or down a few Hz until I 
get the accuracy I wish by repeating the process several times.  Still 
I find +/- 1 Hz is about it, even with the high stability TXCO and 
very adequate warm-up time of about 2 hrs.


If one needs something more accurate, then Don is correct, test 
equipment is the way to go.  And expect to spend big bucks for good 
quality equipment that IS traceable to NIST.   If the NIST document or 
calibration is more than 1 year old, the results will be questionable.


I wrote an article which was published in QST, Sept 2015.   It deals 
with "Transmit and Receive On Frequency".  It shows that digital 
readouts are just that, readouts,  and they are not frequency 
determining or measuring circuits.    And when it is accurate on one 
band it may not have the same accuracy on another band.

With the main K3 fine tuning at 1 Hz steps, I don't know that 0.1Hz 
or even 0.25Hz doppler shift will matter much in the final result.


My frequency counter is good to 10 exp-9 which equates to +/-0.1 Hz 
at the TCXO frequency, so the WWV method provides as good or better 
accuracy, even considering the doppler shift possibility.


The main problem is chasing the beat note down to a stable solid 
note. You usually can't truly get there, but you can get close enough 
that you hear about 10 or 20 seconds between peaks. Close enough for me.


It can be quite expensive to obtain stability better than the K3S in 
an analog oscillator.  My HP8640B signal generator will do that, but 
it takes at least a 3 hour warmup before it becomes stable.  Yes, all 
the internal enclosures in my '8640 have covers with all the screws 
installed - that helps.  OK, that is 'old iron', but I am not going 
to spend several $10,000 for something better.  I have better things 
to do with my money, and no longer have access to modern lab quality 
equipment to achieve that kind of stability.


We have a ham band transceiver - not a precision lab instrument. As 
long as we can stay inside our ham bands, that is all that matters to 
me.  I would not put a carrier exactly on 7,000.00 kHz with any 
transceiver.

Re: [Elecraft] K3 with 2m internal transverter

[Kjeld Holm]

Hi Jim,

You are right I believe. The effective receiver performance is determined by 
the transverter. But especially for EME you would like to have a preamp with 
the best possible noise factor at the antenna to compensate for feedline loss.

Subject: [Elecraft] K3 with 2m internal transverter

Helping a friend to try to get the most out of his 2m equipped K3
especially for EME.

Is it recommended to use the internal preamp when the internal
transverter is in use? I'm guessing "no" due to to 20db transverter RX
gain.

On page 21 of the P3 Owners Manual it describes the integration of the
K3/P3 wrt attenuator and preamp settings. Does the K3 and P3 similarly
communicate the additional 20db gain of the transverter and reflect
that in a downward push of the P3 noise display?

Thanks

I have seen a lot of answers.
These are all true, but what is the exact way of working.

The various reference calibration methods, including direct measurement of the 
TCXO that I do, just determine what the actual reference frequency is, but 
don't change it.

This value is then used internally to compute the correct frequencies.
