Re: [Elecraft] K3s Quick Memories

[Dave Cole]

I use a Genovation Keypad to fire macros at the rig, and one of them is 
a power setting macro.  I would imagine you could use a FN key on the 
P3/SVGA if you have one.

I use Quick Memories 1 through 9 to set the band I want to work, then for each 
band I use M1 and M2 to select either the CW area or the SSB area. Works great.

My question concerns  Power Settings. It seems M1 and M2 do NOT save power 
settings . . . or am I doing something wrong?

Re: [Elecraft] Microphone Jack Cover

Why not use a metal cap from American Radio Supply?  See:

fits the mic connector on the front of the rig.

For those like myself who operate 99 percent CW and don't even keep a 
microphone connected to their K2, K3, K3S, K4, etc, this is a useful item to 
protect both the outer threads of the jack and keep crud from entering the pin

With the proliferation of 3D printers in many ham workshops these days, if you 
don't have one, it should be relatively easy to find someone who has.

Re: [Elecraft] [OT] Ham Radio near high voltage power lines?

[Dave Cole]

Or use a tinySA, and take a look at entire bands at one time...  I have 
found that the tinySA is a real assist in correlating RFI sources.  See:


https://www.nk7z.net/

to get to my base page, or

https://www.nk7z.net/tinysa/

to go directly to the article.

At the end of the tinySA article is a photo of my 80 Meter RFI, as 
viewed by a tinySA, and a 6BTV with 40 radials, ground mounted.  The 
source is 4 blocks from the antenna.  This will give you an idea of what 
you will be able to do with the tinySA RFI wise.


...and to keep it Elecraft related, I will be connecting my tinySA to 
the RX out jack on the K3.

Jerry,

I'm sure you can make something work.  I used to have HV power lines about
150 yards from my house.
It was only a problem during rain/snow/fog with conduction across the
insulators.
I had a cubical quad and could identify the offending pole and could
likewise null out the noise.
Oddly, I don't recall there being a problem on the 80m or 40m dipoles.
You could always do a quick noise check with a mobile HF rig or a handheld
AM shortwave receiver.

Subject: [Elecraft] [OT] Ham Radio near high voltage power lines?

Just moved to a new QTH and there are high voltage power lines cutting
across the corner of our property running NW direction. The house is on the
East side of the lines.

Is it reasonable to expect good operability or is it a wash? I don't want to
go through the troubles if I'll just be frustrated.

Was looking to do a 60' tower for the high bands (I'll still be below the
lines height wise), multiband vertical (low bands 80/40/30) , and
dipole(80/40).

Vertical is planned to have 60 or more radials.

  


Thanks in advance.

I had a similar problem.

I purchased a P3 kit in 2015, assembled, and it worked well.  The firmware as 
received, was a rev behind.  Trying to upgrade via the normal method, was 
unable to accomplish.  Trying to force an upgrade, was unsuccessful.  Had to 
return for warranty repair.  The EEPROM was corrupted.

All was OK until about 4 years ago, the P3, occasionally, would not boot up. I 
received some guidance from one of the engineers, to check a capacitor in the 
P3 power supply.  If it was a tantalum  (10 uF I believe), it was the incorrect 
value, and to change to 0.1uf (1206 sized).  After the capacitor change, no 
more powerup issues.  I believe there was a supply sequencing issue.

I am looking for the details, and when found, I will post.

  Likewise; on power up:

Shutdown the items in reverse order. NEVER just dump the power as there is a

that did not solve the problem. I sent it to Elecraft and it turned out that 
the I/O board was faulty. The repair cost was approximately $200 for a new 
board and labor.

Re: [Elecraft] P3 Failure, and question

[Dave Cole]

Hi Dave New,

It does help, and thank you... Mine has come back to life as well, 
(power cycling it), and I am worried about turning it off now as well...


I will get an RSA from Elecraft and send it in...  I'll report back to 
the list what they find, and how long it took to get repaired.


If you discover the issue, please let me know if you would!  I won't be 
sending mine back tomorrow, but sooner than later.  Also, THANK YOU 
again for the information.

  I've been experiencing intermittent failures of the internal display, 
as well as loss of at least one setting (Track/Fix).


I've been leaving the K3s/P3 powered on continuously, but recently 
started turning them off, to save some 'always on' energy while trying 
to figure out why our house is running about 1200 watts continuously.


So, when powering on the combination (the P3 is set to power on with the 
K3s power), very nearly always now, the internal display fails to come 
on, but the SVGA display always works.  Normally, cycling the power 
switch on the P3 recovers the internal display, but just yesterday, I 
had to cycle the power several times before it came up.


I'm now leaving things powered on, until I can troubleshoot what the 
issue is.  I did go as far as looking in the P3 manual to see if there 
is a coin cell battery in it, that might need replacing, but that is 
apparently not so.


I'm concerned about the loss of settings, which may point to a corrupted 
EEPROM.  Reflashing the P3 hasn't fixed this, and so far, I've not tried 
a 'factory reset' on the P3, which would lose all my settings.


Hope that helps,

-- Dave, N8SBE

Quoting Dave Cole :


Rick,
A further thought on this...  Next time your P3 fails, can you try and 
grab an image from it using the utility?  I just thought of that, mine 
will not grab an image, when it is failed, so it is probably not the 
backlight on mine.

Re: [Elecraft] P3 Failure, and question

A bit more data:

1.  The (3 utility can talk to it.
2.  If I try and capture an image, it goes through the motions, but no 
image is captured.

3.  It accepts commands via a keyboard.
4.  A load from the last config file did not correct things.
5.  A full power off and on did not correct things.

Anybody know, or have experience using an Elecraft PA (a 500 watt in my

We've done that a LOT (at least 6 years) with two KPA500s on Honday 
2000i generators for CQP and 7QP expeditions. Two can run on a single 
Honda, but with some voltage sag between the gen and the unregulated PSU 
in the KPA500. You have to set the "right" tap in the KPA500's primary 
(low, med, high) that hits the "just right" HV so that the KPA doesn't 
protect because it's too high key up and too low key down. With two KPAs 
on a single 2000i, both can be running CW at the same time at about 
300W. Maybe both full power if one CW, one SSB.


W6GJB's contesting trailer is set up for two K3/P3/SVGA/KPA500/KAT500 
stations, which we mostly run on CW. Several years ago, he bought the 
paralleling kit, so we run two in parallel, both in economode, running 
our entire station.


A single 2000i will run an entire single-TX station in economode.

Glen (GJB) has done propane conversions for his 2000i, and recently for 
my new 2200i. There's a company that sells the kit. Much safer and more 
convenient than gasoline.

Hi Brian,

Thank you for the suggestions, and the tidbits of the additional steps for add

I have sent Elecraft three seperate email requests across three weeks, and 
gotten precisely zero replies from supp...@elecraft.com address...

Very dissapointing, not even an acknoledgment they got the mail...  It is like 
firing email into a black hole...

I just resent the 4th request, this time to sales, support, and webmaster in 
hopes I can get in touch with someone at the Elecraft!

I understand things are busy, and I understadn things are diffucult to to 
COVID, etc., but three weeks, and three requests later I am getting very 
frustrated.

Dave,
There have also been numerous component adds/mods over the years. Three that I 
did a couple years ago are 1. Increase the 12vdc accessory power from 500 ma to 
1 A. Evidence is a 1A sticker on the rear of the K3. 2. Add a capacitor to the 
KPA3 to eliminate fan noise pickup evident after the new synthesizers are 
installed. 3. Addition of a capacitor to the KBPF3 general coverage BPFs to 
extend coverage down to the 630 meter band. I’m sure there are others. See the 
mod instructions available on the Elecraft site if you go sleuthing inside the 
box. These are a bit inconsequential but add value to the K3.

Have you thought about asking Elecraft for the work orders for the K3’s S/N?

Good luck and thank you for helping out the family. Sorry you lost a friend.

Hi,

First off, sorry for your loss.


As to options, and especially modifications, I very much would like 
Elecraft to give each modification a number so there can be a sticker in 
a radio that says:


This radio has the following modifications: 01, 02, 03, 04, 06, 08, 12.

That would make these things much easier.

For K2, K3, and the KX-en too late, but perhaps for the K4 this can and 
should be done?

First off, thank you very much for the reply!  I do appreciate it greatly!

That is the info I needed!  I now know the menus will give me most of

anyone been in it!  That makes things a lot simpler!  I do thank you 
sir!  Take care, and and stay safe!  Again, thank you.

Hi Dave;
Since it was here less than a year ago, no need to send it for updates.
If it hasn't been altered, you can get all the options/filters from the 
menus.
If it has been reset for some reason, we can send you the configuration 
file to re-load that was saved at last service.


We don't inventory every radio, but you could load that file into the 
radio and then go thru the menus.
This would be a fairly accurate list unless you believe he 
removed/changed any filters or options, in which case you will have to 
open it up and take out the Sub receiver and open the sub receiver to 
inventory all items.


Someone could also load that file into another radio (I believe it is 
advanced mode of the K3 Utility lets you skip past the serial # 
mismatch) then look thru the menus. Don't forget to save the host 
radio's config file before doing this so you can restore it!

Re: [Elecraft] Inventorying a K3/P3

[Dave Cole]

Hi Brian,

Thank you for the suggestions, and the tidbits of the additional steps 
for add on items like new synths, etc.  I have saved your email.


I have sent Elecraft three seperate email requests across three weeks, 
and gotten precisely zero replies from supp...@elecraft.com address...


Very dissapointing, not even an acknoledgment they got the mail...  It 
is like firing email into a black hole...


I just resent the 4th request, this time to sales, support, and 
webmaster in hopes I can get in touch with someone at the Elecraft!


I understand things are busy, and I understadn things are diffucult to 
to COVID, etc., but three weeks, and three requests later I am getting 
very frustrated.

Dave,
There have also been numerous component adds/mods over the years. Three that I 
did a couple years ago are 1. Increase the 12vdc accessory power from 500 ma to 
1 A. Evidence is a 1A sticker on the rear of the K3. 2. Add a capacitor to the 
KPA3 to eliminate fan noise pickup evident after the new synthesizers are 
installed. 3. Addition of a capacitor to the KBPF3 general coverage BPFs to 
extend coverage down to the 630 meter band. I’m sure there are others. See the 
mod instructions available on the Elecraft site if you go sleuthing inside the 
box. These are a bit inconsequential but add value to the K3.

Have you thought about asking Elecraft for the work orders for the K3’s S/N?

Good luck and thank you for helping out the family. Sorry you lost a friend.

The menu settings would be a good place to start, confirmed by taking 
the cover off.  One receiver is covered by the other, so some 
disassembly is required for the visual of the filters.  Then tuner, 
which i/o board etc.


For the P3, the options are the SVGA board and the TX board.

O.k. I'll bite.   I started in amateur radio long enough ago to know how to use 
a BFO and to know how to zero beat an AM or CW signal.  How does one zero beat 
a suppressed carrier single sideband phone signal?  I just tune until the voice 
sounds like I think the voice should sound like.  It is very subjective and I 
certainly can't tune to less than 12 Hz error.

What technique are others using that enables them to "zero beat" SSB phone to 
better than 12 Hz accuracy?  I seldom use phone but I'd like to have this technique in my 
bag of tricks.

Re: [Elecraft] Copying CW and Pitch

Jim,
Here is an interesting story:

I had a hearing test many years ago, and asked to see the results. 
Turns out I had a null at some frequency I don't remember right now, but 
it was exactly where I had selected my sidetone to be...  My guess is 
because I heard less noise there...  Anyway--


I re-selected a new sidetone, lower in frequency, and on a small peak... 
 My CW speed for copy increased probably 10-15%.


Now whenever I get a hearing test, I ask for a copy, and put the 
sidetone where my highest peak is, within the range Elecraft allows for 
sidetone.

better able to separate signals from each other with RX pitch set to

few folks I had not, and good to get a few answers I needed.  The K4

Navagate to:

Put your call sign in on the top, and see if anyone is listening and 
hearing you...


Go to a band that you are hearing a lot of stations on, and if within 
your class of your license, transmit there by calling a CQ.  After a few 
minutes, hit "Go" on the map.  That will show you who is hearing you.


I just looked, and in the last 12 hours, you were heard all over the

Re: [Elecraft] Big Knob Fail

[Dave Cole]

I think the issue is in shipping...  When, (not if), the shipper drops 
your K3 to the ground from 4 or 5 feet up, and the rig stops with a 20G 
or 30G, (or more), pulse at end to motion, the weighted knob then 
becomes a rather good looking hammer hitting the encoder shaft...  Never 
a good idea...


If someone has a definitive answer to this, I would love to see it...

I fully agree.  I would NOT put a weighted knob on any electronic tuning

Lots of Collins guys like to install those weighted tuning * knobs on their
S-Lines, which were NOT made to take excessive extra wear caused by the
very
heavy knob.

* The "weighted" Collins knob actually has the outer skirt replaced with
one
made of solid brass which is painted satin black to match the standard
Bakelite knobs.
It was never intended to be used on the regular 200 kHz tuning via pinch
roller, S-Line but was designed to smooth-out the klunky tuning in their
51S-1 receiver.
It does great for that.

Subject: Re: [Elecraft] Big Knob Fail

One of the problems with the knobs is that sometimes, people change the
injected molded knob out for a HEAVY machined knob. The mechanism inside
the
radio is not built for this type of installation. A rapid spin with the
angular momentum and torque of the heavy knob will wear out the device.
This will require taking the front panel off and replacing the component.
This has been discussed many times in the past on this forum. It sounds
like
his main frequency control device is worn out/damaged and will need
replacement. I would continue to call Elecraft until I get through to a
technician and most likely have it sent in and fixed.

I wish your friend well in getting his rig fixed. Withdrawal is a bummer.

My buddy Kurt, W6PH, who is not on the list, has a K3S. Recently the
VFO knob has been intermittent and it is now total fail. Does not
change frequency. When he goes to CONFIG or MENU, VFO knob does not
change anything. All other knobs and buttons work including VFO B.

Kurt called Elecraft support and was directed to voice mail.

Any ideas?

Re: [Elecraft] Another Elecraft K4 question

[Dave Cole]

Does the K4 do temp compensation like the K3 does, in very small steps? 
If so, is the step size the same as the K3?


I used to do dopplergrams using my old 756 PRO III, but with the K3 the 
frequency corrections are in steps and mess up the dopplergrams...

The K4 receives on these bands. Transmit output can be taken from the XVTR OUT

Re: [Elecraft] Difference between a K3 and a K3S

[Dave Cole]

Hi,

Remember those filters are Roofing Filters, not the normal filters you 
see in a rig, and use to isolate a CW signal...


The digital filter, (you just dial the bandwidth you want from the front 
panel), in the K3 far surpasses anything I have used in the past, I get 
to very narrow bandwidths, and not a sign of ringing...

There are some options that I don't care about, like the extended receive

Not sure about the transverter but if I find a K3 that has it, fine.  Is the
main reason for getting the transverter option is so you can use the 144
option?

I'm using the recommendation from the Elecraft website to determine the best
choice of filters - 2.8, 2.1, 400, 250 & 200.  99% of what I do is CW and
contests.

I will sell/trade my K2/100 setup to help me make a deal!

tuning capacitor.  Each consists of a 3 foot (91 cm) diameter loop made 
of aluminum tubing and a plastic housing that contains the tuning 
capacitor, motor, and coupling loop.  No control cable is required since 
the control voltage is sent from the control box in the shack to the 
motor in the antenna via the coaxial cable.


Before I purchase one of these I wanted to get an idea of the efficiency 
of such a small loop.  MFJ is silent on the subject so I did my own 
calculations.  The calculations and results are on a 1-page document 
that I uploaded to Dropbox and can be downloaded here:


https://www.dropbox.com/s/l8mv67cjrck2ssn/MFJ-1786-1788.pdf?dl=0

My calculations are based on the assumption that the efficiency of the 
MFJ antennas is similar to the (no longer manufactured) AEA Isoloop (my 
reasoning for that is in the document) and that AEA's specification of 
72% efficiency at 14 MHz is correct.  From that number I can calculate 
the efficiency and gain on all the other bands.


If you don't want to download the document, here is a summary of the 
results:


Freq    Eff    Gain with respect to a half-wave dipole
MHz    dB    dBd
7.0    -7.3    -7.7
10.1    -3.5    -3.9
14.0    -1.4    -1.8
18.068    -0.6    -1.0
21.0    -0.4    -0.8
24.89    -0.2    -0.6
28.0    -0.15    -0.5

I'd be interested in any comments people may have on the accuracy of
my assumptions and calculations in the document.

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

[Dave Cole]

Grant,

All of this topic drift into areas non-Elecraft, (and there is a massive 
amount of it), is a direct result of the moderation efforts Elecraft 
puts into this group.


If the group owners, (Elecraft), wanted things tighter, they would 
moderate more tightly.  If they don't have staff to moderate, then they 
should not worry when things get off topic, which for the most part they 
don't, or close the group.


This style of moderation allows folks to push the limits for short 
periods of time, between moderation events, which is why we get posts 
about everything else.  The longer the time period between moderation 
events, the further topics drift.


This method of moderation almost guarantees topic drift.  I would LOVE 
to see just Elecraft information here, and nothing else...  But not my 
group, so I just delete most non-Elecraft posts.


73, and thanks,
Dave (NK7Z)

Anyone who has ever had a good chuckle or eye-roll over the “interesting QRM”

bleeds over into other places it doesn’t belong, like what should be apolitical

Re: [Elecraft] OT: Thoughts on MFJ-1026 or any other phasing box

[Dave Cole]

Hi,
I have used one of those, and they seem to work great on a single 
specular source...  If you have more than one source of RFI, not so 
good...  If the source is distributed, not so good...  Needs to be 
specular in nature for best results.  I have had better luck with an 
ANC-4, as opposed to the MFJ-1026.


I have a set of articles on RFI location and suppression here:

https://www.nk7z.net/category/info/rfi-mitigation/

That will give you the list of all RFI related articles on my site.

Subject: [Elecraft] KE7X Website Expired

Maybe this isn't new news but the KE7X.com website that is a treasure
trove of Elecraft information seems to be expired and "parked" -- not
accessible. Being new to Elecraft, I just learned Fred became an SK in
May of 2019.

I just received a Lulu.com printed copy of "The Elecraft K3 and P3 -
Third Edition" book for my new-to-me K3 that I bought recently, it's an
awesome reference.

Would there be any interest in re-hydrating his website if we have a way
to get the files/data? I would certainly be willing to sponsor it and
buy the domain/host in the cloud to keep it going since it is well known
and in various print references.


Thanks,

This highly portable SDR rig will have a 6 inch touch-screen/display, offer 
160M-70cm range at 10W output, full QSK, internal tuner and battery.

Additionally, it will have WI-FI, Bluetooth and Ethernet capability.

Full duplex for Satellite ops, naturally, and all of the typical goodies you 
would expect in a portable Elecraft transceiver.

Believe the above is enough to start a lively discussion of what we would want 
to see in the new KX4 (grin).

I’m sure Wayne and Eric are already in the prototype stage of this new rig

One reason we added support for this command is that Joe, VE3VXO, has built a hardware

pattern proportional to the current VSWR." Feel free to contact Joe if you have

Hello Elecrafters,
while we are all waiting for the arrvial of the next beauty, I started
to think what's to improve on my K3 meanwhile. I realized I have always
missed a means to adjust knob friction while tuning. So I sat down and
did the construction and printing (and some iterations of that) and I
got one sample working for me now. It really makes a difference now to
tuning.
Here is my idea:
https://www.thingiverse.com/thing:4694133


Let's see if anybody else likes to have that, too. Please send me a PM
if you do so. If there is enough interest I'm willing to put in the
effort to make it available via a printing service. The price range
might be around $20-30, depending on the material and quality.

Seasons greetings

This is not correct.

For technical reasons, we've been using a somewhat outdated Kernel during the 
past year's development. (This simplified some logistics for the team, while 
having virtually no impact on K4 users.) All current users are getting updated 
along with our development team, and it was completely painless. It'll all be 
history by the end of next week. A one-time reckoning.

Now that we've gotten this task out of the way, all future upgrades should go 
very smoothly. In the vast majority of cases only the application code will be 
updated.

And don't worry: as a user of the K4, you won't have to even think about linux 
OS issues, linux commands, and other arch-nerdly stuff. Updates are essentially 
one-click (maybe two).

Re: [Elecraft] K4 Radio Update

[Dave Cole]

Hi Bill,

Hopefully Elecraft will be speedy with updates, I am sure they will be, 
as they have a superb history of support,


The security aspect was my concern-- freezing the OS is bad, and I doubt 
they will do that.


This however now brings up the question of what happens if Elecraft goes 
out of business.  Hopefully not, but it has to be looked at...


They could then Open Source the code for the rig at that point...  Maybe 
put the source in escrow now, against that eventuality, and keep the 
escrow updated with current code...

I have a problem with my K3s 100w PA: No power above 12w, and receive
signals are down 20 dB. I sent an email to "K3support" a week ago and
haven't received a reply. Is that email address still valid? So, I
resent the email to "support" yesterday -- no response. Has Elecraft
stopped supporting the K3?

To make matters worst, I downloaded the K3s Schematics, and the KPA3A
schematics (Rev C4?) do not match my Rev E PCB. This sure make
troubleshooting a challenge.

I have a fairly large investment in Elecraft equipment, in large part
due to their past excellent support. Do I need to rethink this?

Dave,

I have done many RTTY contests and regular qso's using the 
KPA500/KAT500/K3 over the last few years. I run full 500 watts with no 
problems, the temp gets up to the 60 to 65 range a lot when calling CQ 
in a contest, or during a 10 minute tx.  If the temp gets to 70 then the 
fan kicks into high gear and is very noisy, but still within specs.

Doug,

I lived through cycle 19 of the sunspot signals, and did not find any 
problem with receiver overloading at that time.  We did not have the 
Elecraft gear at that time, but what we had was not up to the 
performance/protection that is typical for Elecraft.  Receivers have 
gotten much better in dynamic range and lowered MDS in general and 
Elecraft rates near the top of the heap.


The AGC in the K2 and K1 (and K3/K3S) can handle the strong signals with 
no problem.  It is not much different than reports of performance during 
a contest where there are strong signals and weaker signals.


If we have a strong sunspot cycle, the weak signals will get stronger 
along with the more powerful stations.

If, by some miracle, the sunspot count were to eventually jump up to a

1959, how would the various Elecraft receivers work? I’m specifically 
interested in the K1 and K2, but in general, is there a realistic 
problem with overloading of the front end? Or, assuming that you can 
hear signals from all over, will the selectivity, etc., be sufficient?

Hi Don,

Good idea, thanks.  I will do just that.  My station is due for a total 
rebuild in the next month, and I will be implementing a patch panel for 
all connections...  That should take care if the issue if that is it...

Dave,

In that case (no relay clicks), I would examine all connections in the 
feedline carefully.
My thinking is that there is something that changes conduction quickly 
(slightly bad connection) when power is applied.


If it starts again, see if it continues when running into a dummy load.

Are you running with the KAT500 in MAN or TUN?
After you have trained the KAT500 to the antenna (see the manual for 
the bin sizes for each band), you should switch it to MANual.  That 
will keep it from trying to TUNe when you first transmit.

Good afternoon K3 folks,

I am new to this list and honored to be accepted.

Recently my K3 has experienced a couple of issues. I have been unable to get
a response from Elecraft e-mail or telephone service regarding the
situation. It's been almost two weeks now so thought I'd ask here if anyone
has some suggestions for me to try myself.

Here is the main concern:

When getting ready for CQWWDX SSB a few weeks ago, I went through setting
the transmit power on each band to drive an amplifier properly. The power
display seemed a bit sluggish and had a delay in indicating the SWR. Worse
yet, when I got to 40M, I could not crank the power up past about 30 watts;
it would momentarily display a higher number but then fall back to 30w. All
other bands cold be set higher.

First I reloaded all the current firmware in the main and subreceiver. No
change to 40M.

So next I went to the K3 Utility ver 1.20.1.15 to do a transmitter gain
calibration. Starting with the 5W calibration, it stepped thru the first few
bands OK but then stopped (I think on 40M) and displayed "ERR TXG" and the
message "calibration settled at 3.6W, TX gain failed because transmit power
did not reach the expected value".

In anticipation of having to send the radio to Elecraft where it might be
totally reset, I manually started recording all the configuration settings.
When I looked at my filter settings, I was shocked to see that filter 1 in
the subreceiver was set to 1.35. Huh? It should have been 2.80 !! Was my
config info corrupted? I reset that to 2.80 and then for the heck of it
tried again to set the power on 40M. That now  worked "OK"  and the swr and
pwr display during "tune" showed instantly on all bands. Something had
changed.

Next, I decided to rerun the TX calibration gain routine. This time if
successfully completed the 5w and 50w routines. However, with a good dummy
load, 40M displays an swr of 1.4, while the other bands are 1.0 or 1.1, so
something is still a little funny on 40M. What might that be?

I have now been considering doing a total reset of the radio using the EE
INIT function and then the self calibrations. Is this wise?

Any experiences or suggestions appreciated.

73,
Chet, N8RA

I was using Winlink Winmore, and it does drive the radio to different

I was not aware there was a Red Cross drill was coming up.  I keep
Winlink around in the event of an emergency, it would be nice to be able

My Winlink setup is based on my desktop machine, (not mobile in any

across multiple updates...

All used to work, and all of a sudden PTT fails.  All else works, the

Re: [Elecraft] [Elecraft-K3] Winlink

[Dave Cole]

Hi Lyn,

First off, THANK YOU for the help!!  I must have been unclear in my 
first post...


I was using Winlink Winmore, and it does drive the radio to different 
frequencies, the radio control is partially working...  It also used to 
work 100%...


I am presented with a COM port, not a USB selection, (Winmore, or Vara), 
when in the RADIO SETTINGS within the program, nothing to do with USB...


I was not aware there was a Red Cross drill was coming up.  I keep 
Winlink around in the event of an emergency, it would be nice to be able 
to get out an email or two in that event.


My Winlink setup is based on my desktop machine, (not mobile in any 
way), which is Windows 10.  It has worked in the past with zero issues 
across multiple updates...


73, and thanks,

Dave -

Windows 10 attempts to lock down USB port assignments as a security measure,
and does so again with each update.  Some apps are smart enough to deal with
this, but Winlink is basically a 1990s era Email application and is
susceptible to issues like this.

There are numerous articles on how to deal with it.  Some that want to sell
you an app to fix it, some that tell you how to fix it yourself (i.e.: The
Windows Club website).  Select the one that best matches your comfort level.
Worst case scenario, you fix it manually after every Windows update.  But at
least you are aware of what needs fixing, and how to do it.

In most cases, you need to go into the Soundcard settings for the Mode you
have selected (i.e.: Vara HF Winlink) and change the input and output
devices to USB Audio Codec.

Are you participating in the Red Cross drill next Saturday?

Hi,

Is anyone using Winlink, (latest), with Windows 10, (latest), and a K3?
All used to work, and all of a sudden PTT fails.  All else works, the
radio is driven to the best frequency, etc...  I have made no known
changes.  There was a windows update...  I would like to verify it still
works, and if so, to get some settings from you...

Silly issue I know, but while I am pleased about and have just about

Re: [Elecraft] KAT500: Fails to tune, and shows 3:1 on good antenna on 18 MHz.

[Dave Cole]

Hi ken,
Added the dummy, no problems, so it is the antenna...  Also, given it is 
a 6BTV with the 18 meter add on, and all other bands work, it is not the 
feedline...


This makes it simple to fix!  It is either a break with the laws of 
physics as we understand them today-- or a connection has come loose. 
Given there are only two connections...  I suspect it will be a simple fix.

Re: [Elecraft] KAT500: Fails to tune, and shows 3:1 on good antenna on 18 MHz.

[Dave Cole]

That helps triage the issue...  Something in my antenna must have gone 
wonky...  I am using a 6BTV, with the 18 Meter add on kit, so the same 
feedpoint is used for all bands, and they are fine...  I was worried it 
was the tuner.  I'll go check the antenna out tonight, and in the 
morning as well...  THANK YOU!  Knowing the tuner is bypassed in Bypass, 
helps...  Next is to put a dummy load on the tuner...

[Elecraft] KAT500: Fails to tune, and shows 3:1 on good antenna on 18 MHz.

[Dave Cole]

Hello,
My KAT500 which worked yesterday, now shows a 3:1 on 18 MHz., only. 
Antenna is a single feedline to a 6BTV, and an analyzer says all is good 
at low power.  At 100 watts, all seems good.


All other bands seem OK at high power.

Question:  When in bypass, is the entire tuner bypassed?
Question:  When turned off is the tuner bypassed?  Which antenna is default?

Very Great to hear you were awarded the ARRL Tech Services Award.. 
you certainly earned it.

It's fun to see you and a few other brains here keep some of the "myths" 
quiet.  Especially the audio related .


As Jim moved to California from Chicago he scooped up my TenTec Titan to 
start his "Titan" collection. Jim & I go back to the audio business in 
Chicago 1980s/90s...   glad I can say this smart cookie is a friend.

Have you been able to get home yet? What's the status of your home and 
antennas?


Got back a few days ago, only damage is to floor under refrigerator 
that had been without power for 3 wks. House, shack, antennas all 
fine. No power, water, or internet, so we're in a rental townhouse for 
a while.

We are getting ready to move...  One of the processes I intend on 
performing on any new site is described at:


https://www.nk7z.net/sdr-rfi-survey-p1/

using an SDR as a site survey tool...  I will have a quiet location...

I used to travel to Malaysia quite often on business, and one of the 
guys who worked for me there as an ex-pat in Kuala Lumpur had gotten a 
9M2 license.  So I went over to his apartment one evening with the 
intention of working some 40m CW as a guest op, but the background noise 
was a horrendous scratchy buzz that ran at least S9+30.  When I went 
outside to look around I could see why.  Malaysia gets a lot of rain, 
things are wet much of the time, and back then (at least 30 years ago) 
many of the electrical insulators on the overhead power lines were dirty 
with pollution.  I could see constant arcing across dozens of insulators.


I'm retired now and live on a reasonably quiet semi-rural hillside, and 
!sometimes! on a quiet evening my QRN level on 160m is down below S2 
even on my Inverted-L.  Counting my blessings ...

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.

I have a 22 db noise floor change here when power fails...  If the pot 
grower has his lights on the noise floor drops almost 40 db during a 
power fail.

Power was shut off to my noisy urban neighborhood yesterday while crews 
replaced a power pole. For a long time, I have wanted to check my HF noise 
floor when the power is out, and yesterday was my chance.  For days like this 
is why my station is solar-powered!

I expected to be surprised but I was absolutely blown away by what I heard. The 
40 meter noise floor was at least *17 dB* lower than normal. I could hear 
layers and layers of signals that I never knew were there. Nets I never knew 
existed… I mean, have you heard of the Montana Sheepherders net, for pity’s 
sake? A midday 40 m pileup on a SOTA QRP CW station in Texas that I never would 
have had a prayer of hearing normally. The noise was so low that I could hear 
way, way down into the intermod of SSB signals—and most of them were quite 
yucky. I heard birdies and crud from washing machines from what must have been 
three blocks away. I heard the 7150 kHz 5th harmonic of a local AM station. By 
measurement on the P3, I confirmed that all of these signals would have been 
completely under my usual noise floor.

On 20, it was so quiet I almost believed that the K3’s receiver had failed. WWV 
was coming in at a 56 dB signal-to-noise ratio.

Interestingly, 80 meters was also quieter, but not by as much. I’m not 
complaining about nearly 10 dB less noise, but it’s too bad that power was 
turned on before dark, before I could really evaluate the conditions.

When it gets this quiet, there are no ticks, crashes or noise transients of any 
kind... just a gentle rushing sound, so it ‘feels’ even quieter than it is. It 
was every bit as quiet as a forest Field Day a hundred miles from civilization. 
Yes, radio was amazing yesterday for six glorious hours.

Ahh.  Well then, I'd bet quite a lot of money that 95+% of that

your trash bin.  You'll never even see it.
