Heathkit engineer (chief engr?, I forget) wrote a letter praising kit 
and radio.? An unbeatable ad!

Congrats! Great amp!

One word of advice if buying a used amp, contact service with serial number and ensure it has latest updates. There were some updates along the way that make the amp more reliable, including additional protection for the LDMOS devices. My amp went back for updates and has been trouble free since.

I Had high reflected errors when running exciter power only which turned out to be issue on frequency detection on filter board.

Renee at Elecraft service waved his magic wand and also applied other updates and it is now running great!

Good advice. Sometimes, at least, updates can be effected with a board 
swap. In my case something failed on the LPF board, but it was easy to swap.

One thing that I've run into is that unless you have trained the 
autotuner across the full range of frequencies on each band, you can 
encounter a kind of endless hunting for a match.? I operate 98 percent 
CW, and when I got into a phone contest I discovered that this would 
happen at the far end of the phone band.? The training is relatively 
quick and easy, but don't be tempted to leave out any of the frequency 
slots when you do it.? Once it's done, it's like having a 1500-watt 
transceiver.

Double check the antenna selection for the sub-receiver. That option is 
stored per-band.

Subject: [Elecraft] K3 Auto ATU Problem
Message-ID: <CABEsYyK5ThS57UnRYT-bEvCWPBkaXH=1xqn3MAM+sMBHjMVg4A@mail.gmail.com>

I'm wondering if someone can help with a KAT3 ATU problem on my K3
S/No.01434?

When bypassed, the K3 SWR indication agrees with that on an external SWR
meter. This is also so when the KAT3 is replaced with a KANT3 board. When
in AUTO mode it goes through its relay rattling sequence for each band, but
ends up with a mis-match as indicated by the K3 meter.

For example, with a 50 ohm load, in BYPASS the K3 indicates 1.0:1 SWR on
all bands as it should. When in AUTO mode the indicated SWR is anything up
to 4.4:1.

I have tried a different KAT3 with the same results. I have also re-loaded
the firmware (version 05.67/2.88/2.88/1.26).

Thanks in advance.

I'll send this to the group before I start taking things apart:

Running KX3 with KXP100 using SignaLink on 40m.? I've been using FT8 
successfully for over a year.? Then last night something new:

When I transmit (either the TUNE button of WSJT--X or replying to a CQ) 
the signal goes out successfully.? When the TX ends, the red LED on the 
SignaLink goes out but the TX red LED on the KX3 stays on.

And --? this is the weird part -- the RX signal is gone -- absolutely 
nothing on the waterfall or from the speaker.

This does not happen when I push the TUNE button on the KX3.

Ideas?

Using CAT on the PC.

TEST CAT on PC turns green.
TEST PTT on PC turns red and turns on the KX3? TX LED.? It looks like if 
I change to VOX the problem goes away, but I've always used CAT in the past.

Signalinnk PTT LED turns on with TX.

If using CAT for PTT, make sure the PTT cable from the Signallink is NOT
connected to the radio. Having two separate PTT types active at the same
time will cause behavior like you described.

That makes a lot of sense, Dave.? Two PTT types active at the same time 
is something that never occurred to me.? Except there's no PTT cable 
from the SignaLink, as far as I can tell.
But Greg AB7R suggested that I update WSJT-X, which seems to have fixed 
the problem.? I'm still puzzled as to why it started suddenly, after 
several months with no problem.

Ken,

The K1 LCD backlight is no longer possible.? The original used half of 
the K2 backlight strip which is no longer available and the new K2 strip 
is too thick to fit under the K1 LCD.

 I did a backlight on my K1 ~20 years ago that worked out well. The key was getting a transreflective LCD panel so the light would show through. The original panel was opaque.? Here's a couple of pix:

Hi Tom,

In your initial post, you failed to state the power level of your failed 
autotune event.

Hence why my question did not ask what the tuning level needed for the 
K3 to trigger was, but at what power level you were performing your 
failed autotuning event at.

My thinking was that you might be below the auto tune trigger threshold.

73, and thanks,

The KAT3 performs well at 10 watts, lower output levels may not get 
consistent results.

Ditto the KAT500 and KPA1500 tuners.

Tom,

Does the problem you describe occur
on each of the ANT1 and ANT2 ports
on the KAT3 output when the ports
are terminated in a good 50 ohm power
load?

Have you checked the K3 ANT selection
when the KAT3 is installed to be sure that
the port to which your 50 ohm load is
attached is the one selected on the front
panel?

The fact that the anomalous behavior
occurs with a substitute KAT3 board,
and that it doesn't occur with the KANT3
board installed, indicates that the K3's SWR bridge
circuit is operating properly.

The fact that putting the KAT3 in BYPASS
mode provides a correct SWR reading
indicates that the relays in parallel with
the series-connected inductors are
properly switched as are the relays
in series with the various shunt capacitors
of the L-network (the latter group of
relays all switched off their connections
to the associated capacitors).

You could try the KAT3 tests using
manual control mode (as described
on p. 56 of the K3 Owner's Manual,
rev. D10) to verify proper operation
of each of the relays in the L-network
individually. The manual control options allow one
to read out or clear the per-band memory of the
ATU L-C settings, which might also
be useful in diagnosis.

As a follow up to Don's great advice, I had a few spare moments today while I was relaxing from some physical labour so decided to crack open the wee little K1 and take his advice.

I compressed the turns on L1 (whoa, is it ever finicky!) but after some playing around my tuning is now:

20m- - -13.0918MHz - 14.0796MHz
40m - - - 6.978MHz  - 7.0858 MHz

I seem to have a little more than the spec'd 80kHz of tuning range, but not as much as the 150kHz of some kits.  I have no history on this thing, but it's all good.
I am very happy with these results.  As long as it won't drift above the lower band edge on 40m once it's warmed up, I think I am going to just leave it be for now.

Thanks Don !

Thank you very much Don !

This is exactly the type of FB information I was looking for.

I rec'd a few emails telling me to calibrate it, however the VFO reads right smack dab on perfect, so I didn't
wish to mess with it by redoing something that may not help.

I'll probably just leave it (at least for now), but your info is very much appreciated and I'll save it for a rainy day perhaps.  
The only time I would ever make a QSO above 7068 or 14063 would be in a contest, and this would not be the rig I'd be contesting with, hi

I have a ton of other rigs (some Elecrafts too....KX3, KX2(on order) and a K3) and some Japanese rigs too.....All are much better suited to contesting.

This lil' guy will see light duty as a Motorcycle mobile (portable, really) rig for Parks or Islands on the air and the occasional Wednesday "CWT" (an activity event like a contest).  I like its simplicity and very small size.  Good for the Harley.

Thanks again Don and all.

What a great bunch !

Maybe see some of you (all of a sudden!) in CQWW CW this weekend.  I'll be 15m single band.

Mike,

The K1 must tune a bit below the low end of each band.  That is to 
compensate for the crystals on the band board not being precision 
crystals - so your K1 is behaving as normal.

You CAN tweak it by a small amount on ONE band (the 2nd band will change 
too).

In your case, I would choose 40 meters since it is only low by 20 kHz 
while 20 meters is low by 26 kHz.
You can do this in receive by looking at the frequency display because 
you have already confirmed it is showing the correct frequency.

Tune the VFO to the low end of 40 meters and then spread (or compress) 
the turns of L1 a little at a time until the display shows about 
6995kHz, then check 20 meters to make sure it is a bit below the band 
edge too.
That is the best compromise that you can do without losing a bit of the 
bottom edge of the band.

Don W3FPR

LED, sanded the plastic case to make it more diffusive, and fed it off 
the 12 volt buss with a current source made from a gate-source connected 
FET.? It wasn't difficult to do.

I don't remember which FET I used, but an LM334 (very inexpensive TO-92 
current source IC) and a 1/4 watt resistor would work even better, and 
today's LEDs are certainly much brighter than the ones I had available 
back when I did this.? Better choice of colors as well.? ;)

 Sounds pretty similar to what I did.? The white rectangle in my photo is a piece of white sticker vinyl stuck to the PCB under the area where the LCD mounts? The two LEDs were sanded down with a Dremel tool and sanding drum to get the light to diffuse and also to make them small enough to shine behind the LCD panel.? The two LEDs and a 680ohm current limiting resistor are all wired in series and draw a total of ~12ma off the 12V supply.? Parts and wires are held in place by dabs of hot glue. 

Here's a closeup of an original and modified LED.

As a follow up to Don's great advice, I had a few spare moments today while I was relaxing from some physical labour so decided to crack open the wee little K1 and take his advice.

I compressed the turns on L1 (whoa, is it ever finicky!) but after some playing around my tuning is now:

20m- - -13.918MHz - 14.0796MHz
40m - - - 6.978MHz  - 7.0858 MHz

I seem to have a little more than the spec'd 80kHz of tuning range, but not as much as the 150kHz of some kits.  I have no history on this thing, but it's all good.
I am very happy with these results.  As long as it won't drift above the lower band edge on 40m once it's warmed up, I think I am going to just leave it be for now.

Thanks Don !

Thank you very much Don !

This is exactly the type of FB information I was looking for.

I rec'd a few emails telling me to calibrate it, however the VFO reads right smack dab on perfect, so I didn't
wish to mess with it by redoing something that may not help.

I'll probably just leave it (at least for now), but your info is very much appreciated and I'll save it for a rainy day perhaps.  
The only time I would ever make a QSO above 7068 or 14063 would be in a contest, and this would not be the rig I'd be contesting with, hi

I have a ton of other rigs (some Elecrafts too....KX3, KX2(on order) and a K3) and some Japanese rigs too.....All are much better suited to contesting.

This lil' guy will see light duty as a Motorcycle mobile (portable, really) rig for Parks or Islands on the air and the occasional Wednesday "CWT" (an activity event like a contest).  I like its simplicity and very small size.  Good for the Harley.

Thanks again Don and all.

What a great bunch !

Mike,

The K1 must tune a bit below the low end of each band.  That is to 
compensate for the crystals on the band board not being precision 
crystals - so your K1 is behaving as normal.

You CAN tweak it by a small amount on ONE band (the 2nd band will change 
too).

In your case, I would choose 40 meters since it is only low by 20 kHz 
while 20 meters is low by 26 kHz.
You can do this in receive by looking at the frequency display because 
you have already confirmed it is showing the correct frequency.

Tune the VFO to the low end of 40 meters and then spread (or compress) 
the turns of L1 a little at a time until the display shows about 
6995kHz, then check 20 meters to make sure it is a bit below the band 
edge too.
That is the best compromise that you can do without losing a bit of the 
bottom edge of the band.

Don W3FPR

Hello Elecraft List

I recently got my K3 back from Elecraft. They'd upgraded it to K3s.

I used to be able to run a cable from the Rx in out area on the right-upper-rear as I face it.

That gave me antenna without the threat of RF into my SDRPlay.

I tried Rx In and Out then pressing RX on teh front, but the S-Meter drops 5 S-Units.
Yeah, signal does go to thje SDR device, but at a huge loss to the regular operations.

What am I not seeing here ?

5 S-units is way too much drop for even a simple T-connector. I see almost
the same loss whether I use a "real" splitter or a simple T-connector.

Bob, you say "right upper rear" which doesn't sound right. That's
approximately where the LINE IN-OUT phone jacks are located. Are you sure
you didn't mean "right center rear?" Your external SDR needs to be
connected to the RX ANT IN-OUT BNC connectors. They're the two left-most
BNCs as you look at the rear panel. Also, check to make sure you have a
good twist connection on both BNCs. If you're using a splitter, its common
connection should go to RX ANT OUT and its two output connections should go
to RX ANT IN and the SDR.

To use the RxAnt In/Out BNC connectors in the KXV3, you need to select the
RX Ant from the front panel RX Ant switch. This means you need a jumper
between RX Ant Out and RX Ant In to feed the RX in the K3, with a tee or
splitter to feed signal to the SDR. If you do not select RX Ant, the only
signal that appears at the RX Ant Out connector is due to imperfect
isolation in the RX Ant relay.

Good Evening,

 ?? A warm and wet week has changed into a cold and wet week. There were 
a few hours of sun around sunrise, sunset, and when the clouds dropped 
into the valleys.? The FedEx driver had to chat for a while to enjoy the 
sun.? It was his first trip up through the clouds.

 ? The sun itself has been mildly active.? Current active zones are 
behind the limb.? Maybe in two weeks the solar flux will break 100 
again.? It is at 88 sfu right now.? The auroral oval is active; 
something must be flowing our way.? Solar wind is due to hit some time

It is the classic first text book in circuit analysis.? This edition has 
many SPICE examples.

Before making an active 4 port splitter, I used one made from a pair of
ferrite rings, the circuit and measured performance details are on my web
pages.

If anyone wants the circuit and construction details of my 4 port active
splitter, contact me off list.

Hello Richard Ferch:

Saturday, December 4, 2021, 8:38:26 PM, you chiseled out:

>?To use the RxAnt In/Out BNC connectors in the KXV3, you need to select the

> RX Ant from the front panel RX Ant switch. 

I have a Mini-Circuits splitter.
It comes off the Rx-Out of the K3s. The other two of the splitter go to SDRC and K3s Rx-In

first off, it seems the SDR device is only getting decent output, vis-a-vis Band, from whatever Band I have the K3 set to.

Secondly, it seems that the K3 then is about 6 S-Units down on the same band than it was without the "Rx Ant" being pushed on the K3.

Through off-reflector correspondence, it appears Bob has a point.? On my 
K-3 (un-updated), I have a Mini-circuits splitter between the RX Out and 
RX In jacks, feeding an Airspy HF+ to support the N1MM spectrum display 
window.? Using an XG-3, I see about a 3 S-unit drop in signal level when 
routing through the splitter, instead of the 3-4 dB I'd expect.? I've 
tried another splitter, with identical results, so I have no idea what's 
going on.

Pete (N4ZR), what do you see with a straight cable linking in/out?

I have no idea about Minicircuits splitters, but my home made one had a
measured 3.1 dB loss at 29.7 MHz.

Only 0.1 dB is "loss" - an unamplified two way splitter will show at 3 dB
reduction in signal level from input to either of the output ports just
due to the split.

Bob (and others),

The SDRPlay is capable of decoding and using the RF out directly.

There is no need for a splitter and it's resulting loss. There MAY be a 
need for an inline ATT on the IF out to the SDRPlay but YMMV.

I have run mine this way for over a year now with no issues. Mine is the 
RSPDuo, and I use the second receiver for the software Spectrum Analyzer 
function and the first with HDSDR and the EXTio Interface. (Get from 
SDRPlay website)

No soundcard, no splitters, no problems, and adds second receiver fully 
controlled by the HDSDR. Also, using omnirig-v2 gives control of your K3 
to HDSDR and allows click in the panadapter to change frequencies on the 
radio etc.

As a bonus, it acts like a crude transmit monitor as well.

Just wanted to share this in case folks don't know about it.

I use a pair of BNC to BNC cables, about 4" long, from the RX OUT and RX 
IN to a "T" connector.? The 3rd port of the "T" goes to the SDR.? I find 
that the SDR input impedance, is nowhere close to 50 ohms,? is high 
enough that it doesn't load the signal on the main RX.?? Again, no 
splitter required.?? No loss encountered.

Yes, one does have to select RX ANT on the front panel for this to be 
active.

I don't know why I didn't think of that.? Just tried it, and there is no 
difference in S-meter reading , so it may/must be a splitter problem.? I 
tried it with another spltter, with and and without the SDR, and, again, 
large drop. WTF???

Mini-Circuits makes a wide range of lab-quality devices. A study of 
their catalog is informative. One type is a hybrid that provides about 
20 dB of isolation between four outputs with about 6.6 dB of insertion 
loss to each. In my professional life, I regularly specified them for RX 
antenna systems for wireless mics in performance spaces for which I 
designed sound systems. If one of these were improperly connected by 
confusing outputs with input, it would show that 20 dB of loss.

I've measured the input Z of one of my K3s -- it's 50 ohms behind a 
bandpass filter that's switched in for each band.

Are you hooking up the splitter correctly?? RX ANT OUT from the radio 
goes to the common terminal of the splitter, and one of the two 
independent splitter outputs goes to RX ANT IN on the radio.? The other 
independent splitter output goes to the SDR.? Sorry to bring up such a 
simple possibility, but sometimes it's the simple stuff that trips us up.

Just a word of caution when doing this. If the SDR input Z is high 
enough, then one needs to be mindful of the length of the cable running 
from the "T" to the SDR antenna input. When the length of that cable 
gets close to 1/4 wavelength (this is 3.2 to 4.4 ft at 50 MHz depending 
on velocity factor of the cable), it will transform the high Z of the 
SDR antenna input into a low Z at the "T" which could load down the K3 
receive path (e.g. 500 ohms -> 5 ohms). If the SDR is close to the K3, 
then it won't be a problem, but if the SDR is placed a significant 
distance from the K3, then it would be better to use two longer cables 
from the two K3 ports to bring the "T" close to the SDR antenna input.

I'm afraid you're right, Dave.? I had the RX output into terminal 1 and 
the line back in on terminal 2, because I figured the "common" terminal 
should be the one going to the SDR.? Great to get this straight, finally.

This only works 1) if the SDR impedance is consistently high from
100 KHz to 54 MHz and 2) the SDR has excess gain to compensate for
the loading from the K3 receiver.

However without a splitter, there is no protection for the K3 receiver
against spurious signals generated by the SDR!

Another option, which I've used, is to connect the SDR to the IF OUT, using the splitter in the P3, or directly to the IF OUT on the K3.

The available bandwidth is the 200 kHz (I think) at the IF, of course.  N1MM and DXLab have an option to specify the IF input instead of using the signal from the antenna.

YES! And that, along with the stub-aspect of the loop to an unterminated 
load, are the reasons for using one of the MiniCircuits hybrid 
splitters. Note, however, that they are passive devices, and like all 
passive devices, depend on all ins and outs be properly terminated to 
meet isolation specs.

Hey guys, replying to my own comments here: the SDRPlay can connect 
directly to the "IF" output not the RF as I misstated in the original post.

Probably a "KPA Jumper Block" ... it is installed for low power

Yeah, unless the splitter is active, the isolation is only going to be 
as good as the source match (i.e. VSWR looking back toward the RF out 
port of the K3). The devil is always in the details.

Interesting.
How would you measure the impedance the sdr rx or even the K3, for that
matter adds to the circuit?
I often wondered this when tuning a bandpass filter, to work with a
receiver, using a return loss bridge, how can you be sure the rx is
50ohm...?

A vector impedance analyzer (VIA) or vector network analyzer (VNA) can 
easily do that when properly calibrated. I used my VNWA-3E.

The K3 is a QRP rig with a KPA3 100W option.  Without the KPA3, the K3's low-power amplifier becomes its final amplifier instead of being the KPA3's driver.

I have the board you describe in front of me.  Mine is 41 mm by 9mm.  The board is intended to pass the output of the low-power amplifier to the antenna in case the KPA3 is not part of the K3.  It is not used in a K3 that has the KPA3.

The 12V Sense Mod 1N4148 is a mod to the KPA3 and is unrelated to the bypass module.  I installed that mod 12 years ago; your K3S/KPA3(A) probably doesn't need it.

Hi Bob,

It has it's limits, but if you can live with them it works FB and is as 
simple as pluging it into the IF port on the back of the radio and 
loading a driver.

Not sure on MAP65....

Subject: [Elecraft] XV222 For Sale
Message-ID: <01ac01d7eacc$ff575360$fe05fa20$@gmail.com>

Greetings,

 

I have an XV222 for sale. 

 

Set up to work with 1mW drive from a K3.  Testing on the bench, it meets
factory specs, but in operation it's a little flaky.  It works OK most of
the time on CW and SSB, but is not really stable enough for digi mode
operation. Whoever built it had no business ever picking up a soldering
iron.  It has the crystal oven and I have both the assembly and operating
manuals.  Pictures in a Google Drive folder here:

https://photos.app.goo.gl/p7mZY6fgMRf5FgFA6 

 

Asking $200 or best offer.  Free shipping in the US via Priority Mail.
Overseas shipping (well.international shipping, nobody "overseas" has 222
MHz except Somalia) available at buyer's expense.

 

Thank you.

  Wow.? I'd like to have an XV222, but that one looks like it needs  
some TLC.? That's about the most atrocious soldering job I've seen in  
a while.

It's a miracle it works at all.

I have both the 2M and 70cm versions, so an XV222 would fill out the  
triumphirate.

 From the 3rd port of the T I use a BNC male to BNC male direct to the 
input on the SDR.? Thus my "cable length" on the input of the SDR is 
about 1".

Good point however.

Message-ID: <CABEsYy+srecdhmRrgFST6oJba+hdQE9_yjULtjW=7MOW=tMpug@mail.gmail.com>

Thanks NK7Z, NK7I and K8CN for responses.

Dave and Rick indicated that running the K3 at a higher power level during
the ATU Tune sequence might solve the problem however, as far as I can see,
the power level is fixed at 5 watts during auto tune and cannot be altered.

Mike, there is no problem with the Ant 1 and Ant 2 ports and manual
selection of L & C works OK. The ATU just won't end up with the right
settings for lowest SWR. The problem has not always existed.

Tom

I've found that pressing tune again, immediately after a tune sequence sets it off to do "fine tuning" which might help.

You can set TUN PWR in the K3 Config Menu to something other than 5 watts.

Thanks David - yes I've tried that, but it still ends up with a poor
indicated SWR. Also cleaned up and tightened the screwed pillar in the KAT3
corner, tightened up the 3 LPA screws underneath. It's very strange!

I need advice for getting N1MM+ to play well with a K2.  I have tried it
with two different K2 rigs:  a K2 with a KIO2, and a different K2-100 with
the built in IO.  Same problem.  The K2 Port parameter is set to ON and N1MM
tracks the RX frequency, so I know the rig and the computer are
communicating.  But a keyboard command from N1MM to the rig returns the
error message --  "Unable to send this CW because there is no CW Port set in
Config."

But the CW box in the N1MM configuration screen IS checked, and "set," and
config is: 4800 N 8 1 DTR and RTS Always On (and every other possible
combination thereof); Radio on Nr 1, and PTT via radio command mode CW.  I
have also tried every possible permutation of KIO2 and KUSB cables, on both
rigs, in case of a badness there.  No change.  Same problem every time. 

I know that when using my K3 with N1MM it's necessary to have the K3's menu
settings for DTR and RTS set properly to CW to match the settings in N1MM .
. . but I have found no such option in the K2 menus.  I have also read that
it can be done using a W1EL keyer, but having outboard dongles sort of

Can it be done with just the K2/KIO2, a KUSB cable, and an ordinary

Message-ID: <0E0E66BF-DC07-4588-AF4D-A1FA9B2A007B@dremy.com>

I am in the process of getting familiar with my newly acquired KX3 purchased for POTA and am enjoying it immensely.

I am powering it with a 14.8V, high quality, Yamaha walwart - very little internal noise. Settings indicated in the  VFO B display area using DISP are normal.

When I set the PWR level to 10 watts and then key the xmtr, the power immediately drops to 5 watts.  With the key down, I am monitoring the VFO B display which indicates a drop from 14.8V to 10+V and 1+A.  That makes it 10W.  If so, why does the reading when I push in PWR drop to 5W?  Is that ?input? power vs ?output? power, ie, 50% efficiency?  

If that is true, how does one achieve and maintain 10W of output power?

Any help would be most appreciated. Feel free to RSVP here or call if you like - or send me your number and I?ll call you!

Hi David,
My guess is that the walwart is unregulated or has very optimistic 
specs. You could also be getting RF back into it. I never power serious 
radio gear with walwarts, even HTs. There's too much junk out there.

I have a Bioenno 12V 4.5A battery due any day now.  If what you say is true, that should solve the problem.  Alternatively, I need to complete my PowerPole rewiring of my main 30A P/S and then tap into that. 

Thanks so much for the advice.

Looks like the wall wart cannot provide the 2.5 A needed for transmit. The drop to 10 V automatically triggers dropping to 5 W.

If you want a small supply, the KX-33 can provide 4 A at 14 V.

Message-ID: <CAOmq0YbUBnpEuJa+5M6hUXnVznvYtF3zquCTHY_yjhwRP91wAw@mail.gmail.com>

Ted -

Ultimately, N1MM+ needs to talk to a keying circuit which will then drive
the KEY IN jack
on the K2.  I've had very good results, for example, with K1EL's
WKUSB-SMT.  I got that when
I no longer had a PC with serial or parallel ports on it.  In an earlier
incarnation, I had N1MM
drive a one-transistor keying circuit that was, if memory serves (it was a
while ago), connected
to a serial port on my PC ... and defined as such in N1MM.

Good luck -

Remember that the DB9 connector on a K2 is NOT a standard RS232 
connector. Study the manual. To send CW via the computer serial port, a 
"level shifter" is needed. It's been a while, but I think I remember DTR 
driving a generic PNP with 5K in series with the base, and the collector 
to the K2 key input, emitter to keying return. Someone will correct me 
if I'm wrong.

Ted,

You should be using the special cable from the PC (or USB to Serial 
adapter).
That cable has no RTS or DTR wires in it, so it will not work for 
sending CW from N1MM.? In other words, DTR and RTS are not implemented 
in the K2.

Do NOT try to "fix" it by plugging the USB to serial adapter directly 
into the K2 - if it does not damage the K2, it will cause "strange 
happenings" in the K2 operation.

Either a 'one transistor' keying interface, or a K1EL Winkeyer will have 
to be used between the USB to serial adapter and the K2 key jack to make 
N1MM send CW in the K2.

Don W3FPR

The KAT500 will enter a fine-tune mode if you re-initiate a tune cycle 
right after the first one has finished.? I don't know if the KAT3 will 
do that, and I can't test it because mine always finds the primary match 
the first time, but Elecraft would have a lot of incentive to reuse KAT3 
algorithms and code in the KAT500.? I believe the Elecraft tuners use 
some variant of the steepest descent algorithm which can hang up on a 
less than optimal solution

Aye, Tom - you've given us a good puzzle
to solve!

Back to looking at the schematics, possibly
opening up my K3 to do direct visual inspection.

What, if any, options do you have installed
in your K3 (including KPA3 100 watt PA)?

The KAT3, KAT500, KPA1500 tuners, all have the same feature.? I have all 
three.

If you want a finer (lower SWR) value, within a few seconds of the first 
tuning cycle stopping, start the sequence a second time and the tuner 
will cycle through ALL possible settings to attempt a lower match.? It 
may/not make a difference.

I would also, at this point, seek out an antenna analyzer to see what 
data could be gleaned from that; perhaps a cable, connector or other 
antenna system element (anything beyond the tuner, even IN the radio) is 
no longer valid.? Tuning into a KNOWN 50 ohm dummy load may show 
something interesting as well.

Again, setting CONFIG | TUN to 10 (watts), should help resolve your 
issue, 5 watts is a touch low.? If it does not, you may have a failed 
component (or relay) in the tuner.

If you can, try to eliminate the possibilities (antenna, feed, 
connectors) to find out what failed/changed; narrow the search.? (Does 
another radio tune the antenna easily, EVERY time?)

Yes, and even more than that.  Phil and I corresponded off-list more than

Tom,

I'm going to go out on a limb here, but hey,
it's only a virtual limb!

I am going to withdraw my previous statement
that the K3 SWR bridge is operating correctly.
Given what you've said, the ATU control algorithm
is receiving bad information from the SWR bridge.

Here's how to test this hypothesis:

-- use a different resistive load than 50 ohms, e.g. two
50 ohm loads in parallel using a tee-junction,
or build a higher resistance load using
several non-inductive power resistors, or
use a 4:1 balun reversed to present a 200 ohm
load to the ATU when balun terminated in 50 ohms.

-- put the KAT3 ATU in 'bypass' mode

-- measure SWR at low TX power (whatever
power the ATU uses automatically is fine
as long as your loads can tolerate the dissipation
briefly).

Schottky diodes D36 and D37 in the K3
SWR bridge detector circuit are known
to be sensitive to high voltage transients,
e.g. ESD or lightning-induced voltages.
Failure of either or both diodes produces
bad SWR estimates, which may not
be observed when using a good 50 ohm
termination.

If you have a good high impedance DC
voltmeter (DMM), you might check
the voltages VFWD and VREFL at the
outputs of the LM358 op amp unity
gain buffers (U16 on the K3 RF board)
to observe how each behaves with
different load resistances at the ANT
port(s).  If the VREFL voltage doesn't
change predictably with mismatched
loads, it could be that diode D37 has
failed.

A search of the old Elecraft reflector
and the separate K3 groups.io forum
reveals lots of discussion about anomalous
behavior of the ATU, frequently associated
with SWR bridge component failure.

The K2 serial interface does NOT support DTR or RTS. It only supports three wires - TxD, RxD and Ground.

One CAN run a K2 with KIO2 or KPA100 on a single serial port and key CW. But you have to build your own adapter to take the DTR signal and key the rig through the KEY connector. The adapter consists of a transistor and resistor, so it can be easily built into a connector housing.

Jim,

Since the K2 has a positive key voltage, an NPN transistor is necessary. (eg 2N2222, 2N3904, etc) Alternatively, one could use an enhancement-mode N-channel FET (eg 2N7000, etc).

I made a simple modification to allow this. I don't use ALC, so I 
repurposed the ALC pin in the interface connector. On the control board 
I added two 1n4148 diodes, cathodes to the former ALC pin of the 
connector and anodes to the dit and dah lines that go to the paddle.
Then I connected that wire in the plug that goes to the computer serial 
port to the DTR pin.

At this point all you have to do is activate the K2 feature that allows 
simultaneous closing of the dit and dah lines to be treated as a 
straight key, and set up N1MM for DTR keying.

On my K3, (Tech Mode on, just for clarity):

Config | TUN PWR? is set at 10.0 watts.? If I want it set at another 
level, I turn the main VFO knob to set that level.

I just tested that into a dummy load after setting the output per above

HI,

After a bit of button pressing I have noticed the following:

When doing a first tune using the internal ATU the tuning power is a set 
5W. Immediately doing an extended tune the tuning power toggles to 10W. 
It does indeed flash up in the VFO B window whilst tuning is in progress.

This is in no way controlled by any power level set by CONFIG>TUN PWR. 
My CONFIG>TUN power setting is 18W which I use to preset my Acom 1000 
amp tuning.

Regards,

Mike VP8NO

Good afternoon,

My P3 was just returned from Elecraft, where I sent it for repair
(lightning).  The SVGA card was in the box with paperwork saying the U502
voltage regulator was replaced, but the unit was unrepairable.

Is there anyone on the list who would be willing to try and repair it?  I
know there was a discussion recently and I saved it (somewhere).  Wish I
could find it.

KAT500 has an input attenuator that may, under certain conditions, be activated during a full search tune.   Page 1 rev C of the KAT500 schematic shows the attenuator is a divider consisting of R6 and R7 which are both 39 ohm.  My KAT500 serial number 2609 does not have R7 fitted and R7 is shown as not populated in Figure 17 of KAT500 User's Manual Rev C6.

The removal of R7 changes the potential divider into a simple series resistor and my measurements show my KAT500 presents a very poor match to my TS-590 exciter when the attenuator is active.  In this example the KAT500 was in bypass and connected to a nominal 50 ohm dummy load.  The impedance presented to my TS-590 by KAT500 was measured with an LP-100A:

Att Out:  R 48.1, X 2.4, Pwr 4.48, SWR 1.06
Att In:      R 22.3, X 162.6, Pwr 0.55,  SWR 9.98

Do other KAT500 owners see similar results? (Attenuator can be switched in/out with KAT500 utility)

Can someone please explain why the attenuator was changed.

Andy -

My KAT500 (s/n 2916) behaves pretty much the same way.  I don't know if R7
is present, but tuning into my normal antenna produces these results:

Man/Auto (doesn't matter): Att Out = SWR 1.00
     "    "           "           "         Att IN = SWR 99.99

My guess is that the KAT500 cannot get a strong enough signal to tune
properly with the Attenuator IN.  Interestingly, when it was new, it did not
have that problem.  Perhaps R7 has failed.

73
Lyn, W0LEN

PS - Where did you find KAT500 rev C schematics?
Thx.

Hi Lyn,

Thanks for your report.  Your KAT500 is a later serial than mine so I doubt R7 is fitted. (Mine was a kit build and I don't know if factory units are in the same serial number series)

I don't know the source of my Rev C schematics.  I received some of my KAT500/KPA500 from Elecraft support and some by an internet search.  I assume there must be a later version that documents the elimination of R7.

73,

Guys,

I'm not about to remove all of the cables to look but using my iPhone camera it 
looks like I have S/N 1418, which I kit-built.

My R7 is AWOL and R6 measures about 228 Ohm.

Looks like Elecraft needs to explain.

Elecraft K1 modifications
Searching for K1 modifications, I found JL3AMK and his website
for Power increased on an Elecraft K1.
Refers to page 79 in the Elecraft manual, DRIVER Q6, 2SC2166.
Resistor 30 is attached to Q6.

Is this a safe or recommended mod?
Did you perform the modification?

Power Increased

The output power of my K1 was four watts on 15 meters, so I added a
 0.001uF capacitor (as a bypass) in parallel with R30 on the RF board.

160m: 10W (not changed)
80m: 10W (not changed)
17m: 7W (from 6W)
15m: 7W (from 4W)

Mike (K8CN) and others - thanks for your inputs. I'm talking to Paul at
Elecraft Tech Support who, by the way, is being most helpful.

He reckons I have a problem with the Low Power Amplifier which takes a few
seconds to come up to full output power. I'm not at all sure how that
affects the SWR measurement and ATU setting, but I'm going to follow along
with his advice and see where it gets me!

Then perhaps I'll start looking in detail at the SWR bridge components.

The rig has a 100 W pa and second Rx Mike.

*Tom,*

*I'm going to go out on a limb here, but hey,*
*it's only a virtual limb!*

*I am going to withdraw my previous statement*
*that the K3 SWR bridge is operating correctly.*
*Given what you've said, the ATU control algorithm*
*is receiving bad information from the SWR bridge.*

*Here's how to test this hypothesis:*

*-- use a different resistive load than 50 ohms, e.g. two*
*50 ohm loads in parallel using a tee-junction,*
*or build a higher resistance load using*
*several non-inductive power resistors, or*
*use a 4:1 balun reversed to present a 200 ohm*
*load to the ATU when balun terminated in 50 ohms.*

*-- put the KAT3 ATU in 'bypass' mode*

*-- measure SWR at low TX power (whatever*
*power the ATU uses automatically is fine*
*as long as your loads can tolerate the dissipation*
*briefly).*

*Schottky diodes D36 and D37 in the K3*
*SWR bridge detector circuit are known*
*to be sensitive to high voltage transients,*
*e.g. ESD or lightning-induced voltages.*
*Failure of either or both diodes produces*
*bad SWR estimates, which may not*
*be observed when using a good 50 ohm*
*termination.*

*If you have a good high impedance DC*
*voltmeter (DMM), you might check*
*the voltages VFWD and VREFL at the*
*outputs of the LM358 op amp unity*
*gain buffers (U16 on the K3 RF board)*
*to observe how each behaves with*
*different load resistances at the ANT*
*port(s).  If the VREFL voltage doesn't*
*change predictably with mismatched*
*loads, it could be that diode D37 has*
*failed.*

*A search of the old Elecraft reflector*
*and the separate K3 *groups.io* forum*
*reveals lots of discussion about anomalous*
behavior* of the ATU, frequently associated*
*with SWR bridge component failure.*

Message-ID: <170f938392397f25db7bbb4712190493bd591e23@webmail>

When using the tuner only (amp on standby), ATU tune works fine, but
observing the PWR it ramps up slowly from 0 watts. For example K3 set
to 100 watts, amp on standby, press ATU tune and it takes about 15
seconds for the amp PWR indicator to reach 100 watts. Is this normal?
There is no noise from the tuner during this time.

I don't know anything about the KPA-1500, but I have seen similar power 
ramping if I have K3/config/TX DLY set too short for my AL-1500 amps.? 
With that amp, I have to set TX DLY to 14 msec.? What happens is that 
the K3 sees a momentary high swr before the amp relay closes, and 
throttles back power.? Sometimes you can even see "high swr" flash on 
the K3 display.? The power then slowly ramps up as the K3 recovers.

Dave, changed the K3 Tx Delay from normal setting of 8ms to 14ms and
K3 puts out full power as soon as amp tuner completes. I'm using a
non-resonant antenna on 60m, so just wanted to use the tuner in the
amp.Thanks for the tip.Bill K4MWB

I don't know if this is useful, but I have noticed that my KXPA100 with 
ATU takes a few seconds to ramp up, or at least to light all the LED's 
up to 100W.? This happens only on the first transmit after sitting 
awhile and I just assumed that it takes a few seconds for the coils, 
etc. to warm up.? After the first TX the jump to 100W is immediate.

 I am offering for sale my factory built Elecraft K3S-F and my P3-F.

These units were purchased new by me and used exclusively in my temperature
controlled, pet and smoke free ham shack.  Both units have seen very little
use, especially the last three plus years as I have spent virtually all of
my radio time on my KX2 and KX3 operating QRP.  Listed below are the
details & original purchase prices:

Elecraft K3S-F serial #10609   $2,300
KPA3A-F  100 W UPGRADE $600
KAT3A-F   ATU   $370
2X 2.7KHZ FILTERS  $0
KBPF3A-F  K3 general coverage RX module $180
KBVR3-F  K3 Digital Voice Recorder  $150
2X KFL3A-1 1.8-IR-F  1.8KHZ 8 pole roofing filter @$140/ea  $280
2X KFL3A-400-IR-F  K3 300HZ, 8 pole filter @$170/ea  $340
KFL3B-FM-IR-F  FM bandwidth 8 pole roofing filter $140
KRX3A-F  K3 2nd RX  $680
KFL3A-2.7-F  2.7KHZ 5 pole filter  $0

Total cost: $5,040

P3 Panadapter Factory built   $800

So, the K3S plus the P3 cost me $5,840

K3S-F sale price: $3,150
P3 sale price: $550

If purchased together, $3,500

Shipping and insurance extra.  Shipment to the U.S. and Canadian addresses
only, please.  Payment by PayPal or Zelle preferred

These units are boxed in the original Elecraft factory boxes and include
all manuals and the cables they were shipped with originally.

Looking for the simplest way to remote an SDR to the other end of the lot
to use as a local receiver. I live in an apartment and that is no place to
put a receiver. I have a constant S9 noise level on most bands. I am
thinking of hanging my SDR in my garage half a block away where there is
almost no noise on most bands. It would be nice to have it listen to my
frequency automatically. Any ideas for a simple, inexpensive way to try
that out. Thinking of a wifi link through my network to my shack computer.

Hello fellow Elecrafters,
I'm getting ready to sell my rarely used K3 and am having a tough time 
figuring out a fair price to ask for it. It is an unmodified original 
K3/100, with the KSYN3 original synth, with the KFL3B-FM, KFL3A-6K, 
KF3A-2.7K, KFL-500Hz and KFL3A-200Hz roofing filters installed. It also 
has the KBP3 Rev A general coverage receive board, the KIO3 and the KXV3 
IF in/out board. I also have an uninstalled KRX3, with the KFL3B-FM, 
KFL3A-2.7K, and KFL3A-500Hz roofing filters installed, and the original 
KSYN3 synth. Everything works fine and is in great shape, but I have no 
idea how to price it. Any advice would be appreciated.

Message-ID: <ED16E371-9F9B-4CD7-84C2-D6CA00DAAE08@gmail.com>

The Sunday December 12, 2021 edition of the Elecraft 20 Meter SSB Net saw horrible solar numbers but a respectable 31 stations joining the net.  As always a big shout out goes the the relay stations.  Without the relay stations checkin numbers would be considerably lower.  Thanks to relay stations Eric WB9JNZ, Roger N4NRW, Bill AE6JV, Steve WM6P, John N6JW, Brian K1NW, Phil NS7P and all that stations that take time on Sundays to join us.

Of particular note was Peter ZL1PWD from New Zealand with a good signal to the Western states and copyable in Colorado.  Thanks Phil NS7P for your efforts with Peter each week and of course thanks to Peter for making time to join us on Sunday.

And it was also fun to hear John?s KX3 bicycle mobile near his California QTH.  John had a great foot print with good signal reports from SC and RI.  John?s bicycle mobile KX3 install could  hear Peter from New Zealand.  John was even able to assist with relays before pedaling home.

Eric WB9JNZ, primary NCS, is in the process of moving from his old QTH in the urban Chicago area to his new more rural location northwest of Chicago near Woodstock.  Eric promises to have his K3/KPA1500 online with his new antenna farm soon.

And the number of K4?s joining us continues to grow.

The Sunday Elecraft SSB Nets begin with the 20 Meter Net at 1800 UTC on or about 14.3035 MHz with Eric WB9JNZ as NCS in Chicago. The 40 Meter SSB net follows at 1900 UTC with Steve WM6P in Georgia serving as net control on 7.280 MHz.  At 0200 UTC the 80 Meter SSB Net meets on 3.775 MHz with rotating net control stations.  We employ several relay stations located around the continental USA to assist with check ins.  As conditions permit we take questions and comments after check ins

Tom,

Glad that the MotherShip is helping out directly!

It wouldn't have occurred to me to look at
the LPA stage as a source of trouble, but if
the TX power is ramping up slowly, then I can
see where the ATU control algorithm is
confused by the change in power levels both
forward and reflected.  My ATU seems to
change relay settings very fast, and the control
algorithm is looking at change direction (maybe
change magnitude as well) in SWR to decide
which relays to flip next.  The relative adaptation
speed of the control algorithm and the TX power
ramp-up could certainly cause interactions that
might slow the ATU convergence, but I would
think that once the TX output power stabilized,
the ATU control algorithm would be receiving
valid SWR readings as it flips relays.

When you say it takes seconds to ramp up
to full (TUNE) output power, does this happen
on every TUNE button press?  Does it also occur
when you send CW from the paddle/key? Can
you watch the RF envelope on a scope to time
the power ramp-up?

Note that this net is on December 12 in north america.

I was a bit confused, misreading the clock on my computer, so I 
started the net at 0115z, when the previous net, which has been 
running for 35 years ended, instead of 0200z. Thanks to Jan K1ND 
who acted as a relay station.

Note that the numbers of K3s and K4s were tied.

Just went through different antenna configurations and bands. Using the 
KAT500 Utility, selecting the ATTENUATOR and then TUNE on my K3S shows a 
SWR of 1.5:1 and when the ATTENUATOR is not selected the SWR shows 
1.1:1. ? An external SWR/PWR meter in the line between the radio and 
KAT500 shows the same values.

In receive mode, I hear a relay click when selecting the ATTENUATOR and 
again when de-selecting the ATTENUATOR.? Also noted the RX signal drop 
about ~3 dB {maybe less} when the ATTENUATOR is selected.

I did notice initially when selecting the ATTENUATOR it seemed to be 
inconsistent in results for a few times.? I figure this is some issue 
with relay contacts.?? Once exercised 3 or 4 times,? no further strange 
operation was observed.

Don't have a clue if the resistors in question are installed or not.

I recall that certain ICOM tuners insert an attenuator on the input when 
running the tune routine.? This is said to provide a constant 
impedance/load to the transmitter while the tuner runs through its range 
of L and C values.?? This of course is for a radio that folds back power 
when the SWR is >3:1 or so.

--------------------
I sold my K3 a few weeks ago for 1600 GBP (around $2000) plus carriage or
collection, it was serial #80 from late 2007, with updated synths, second
RX, 1 x 6K, 2 x 400 Hz, 1 x 250 Hz and the 2 x 2800 Hz 8 pole filters that
are normally fitted as standard in each RX, general coverage board in main
RX, KIO3 and DVR board. The package also included a basic P3 pan adapter.
It was advertised on here and a UK flea market page.

I had an email from a well known K6 who seemed keen to buy, but not sure he
wanted to pay the asking price, he has a lot of Elecraft gear listed on
eBay and eHam. I was not willing to ship to California.

There were two UK hams interested, one was a time waster the other
brilliant, he paid the asking price and arranged collection by DHL. I had
tried dealers for a trade-in, but not one was interested in an old K3.

I'm not sure UK prices equate to what you might obtain in the USA, but few
seemed to be interested in buying an elderly K3.

Bill,

Oops!  I've not upgraded to a K4 (yet)!

Please correct to a K3s, with a KPA500 afterburner.

And Tim is running a Yaesu FT-450D exciter.  He does, though have a

Mike,

I searched the Elecraft Support pages for mods
on the K3 and K3s, but found nothing about
"protection diodes" for the LPA (low power
amplifier module).  I did a search of the
archives on the official reflector and again
found only your mention of "protection
diodes" for the LPA.  I have not yet checked
the K3 groups.io forum - perhaps there is
discussion of the need for such diodes there?

Rich,

I wrote to Elecraft in late October 2021 to inquire
about the status of options and upgrades.  I don't
think Madelyn reviews the many emails on the
official reflector, but she kindly answered my query
via direct email.

As of early November, the estimate is 4-6 months
for most K3/K3S options and upgrades, but Elecraft
intended to publish to the Shipping Status pages updated
delivery dates on individual items as their availability
becomes more certain.  Long lead time parts and
board vendor capacity is the bugaboo here........
pretty much the bane of the entire electronics industry.

I took the cover off mine and verified that the shunt resistor was missing and 
the series one measured 228 ohm.? Clearly, if this is dynamically switched while 
seeking a match the poor exciter is going to be totally confused.? The 
attenuator should have been implemented with two 30 ohm resistors in the first 
place.? What motivated them to remove one is a mystery.

The fact that mine appears to have changed value says to me, that while clever, 
the use of the bottom panel for a heat sink is problematic.? I suspect this is 
also the case in the K3/K3S LPA where there are a lot of FET failures.

"I took the cover off mine and verified that the shunt resistor was missing and the series one measured 228 ohm.  Clearly, if this is dynamically switched while seeking a match the poor exciter is going to be totally confused. "

The list and private replies I have seen seem to show the attenuator with both resistors presents a reasonable match to the exciter.  The attenuator with R7 removed presents a horrible match to the exciter.

With the single resistor attenuator active my TS-590S load is so bad that it folds back to very lower power output, far too low for the tuner to continue the tune cycle, so it would then switch out the attenuator.  However, I don't see any sign that the attenuator is ever switched in circuit on my KAT500.  I have only recently added ATTN to my monitoring and recording so I have no data from firmware 1.75 or earlier.  If I get bored I may load 1.75 to see if I can detect attenuator activation.

Subject: [Elecraft] Elecraft K3 with uninstalled KRX3 for sale
Message-ID: <a2427362-9fc2-2b0a-9a29-9a3a15e7fddd@gmail.com>

I have an Elecraft K3, SN3019, and a uninstalled KRX3 that I'd like to 
sell. I'm offering it here first, as this is where I originally picked 
it up.


K3/100 with original synth board, works as it should.
The configuration:
KAT3 internal tuner
KBPF3 general coverage board
KIO3A I/O board
KXV3 RX antenna/transverter board
KFL3B-FM 13kHz filter
KFL3A-6K AM filter
KFL3A-2.7K SSB filter
KFL3A-500 CW filter
KFL3A-200 CW narrow filter
With all manuals and a Cady K3 book.
Pics available on request.

KRX3 with original synth board, not installed in K3:
KFL3B-FM
KFL3A-2.7K
KFL3A-500
with manuals.

I'd like $2300 for both the K3 and the KRX3. I'd prefer not to split 
them up, unless I get strong offers for both.

I also have a PR6-10 that I'll include for an extra $145, or I can sell 
it separately after the rig sells. If these prices are out of line, let 
me know.

I can't help with that error but you can download the firmware directly from here:

https://ftp.elecraft.com/KAT500/firmware/

Put it in a local directory then point the utility to that directory and it should show it is available for loading.

Last weekend during the 10 meter contest I was experiencing very loud 
line-noise-like interference when my antenna was pointing south.? I 
tried both my K3's Noise Reduction and Noise Blanker functions, and was 
unable to find any setting that gave useful relief.? With the noise 
blanker, in particular, I noticed that when it was on, not only was the 
buzz still very strong, but it seemed as if all CW signals on the band 
were being hum-modulated.? As soon as I turned off the noise blanker, 
the CW signals cleaned up.? Is there something wrong with my radio, or 
an adjustment issue, or is this interference simply too strong?? 
Obviously, I'll be trying to track it down, but it's not there all the 
time, so that could be tough.

I have that same issue...
I have some very dirty grow lights about two blocks from me.  They are 
dirty as they come...  Splattering across 80-20 meters.  The K3 has 
never been able to adequately clean up the crud from them.

In defense of the NB/NR on the K3, the signals are on the order of S7 to 
S9, so my expectations may be too high for the K3.  I just hope the K4 
NB/NR work better in my environment.

For 12 years I've tried to get any enhancement of s/n from the K3 IF/RF 
NB and NR.? I haven't seen one case where there is any improvement under 
contest conditions.? When the s/n just starts to improve, the desired 
signal is modulated and degraded by nearby signals to the point where 
reception is better with NB/NR turned off.? As far as I can see, both of 
these features are useless on the K3 under contest conditions.

I too was skeptical about finding ANY improvement to s/n ratio under
contest conditions.

A couple of years ago, I was confronted with some S-7 broadband
digital-like RFI while using my K3 in an extremely urban environment.  But,
using BOTH NB and NR and fiddling with settings eventually allowed me to
operate and to make a whole bunch of contest QSO?s in CQWW CW.

It is possible - but still unpleasant.

The problem of all signals distorted can be cleared up by adjustment. I 
don't know which blanker you are using (RF or DSP), but try reducing the 
blanker level until signals sound normal. Then strong noise pulses will 
still be supressed.
The RF blanker also has three choices of pulse width in addition to 
various levels, which can help with different types of noise. The DSP 
blanker can cause distortion when its level is adjusted to the higher 
levels.
The NR will not help with this kind of noise. It just reduces band noise 
in the background.

The approach I use for the Noise Blanker is this.

I first activate the NB and then the Level.?? I start with the DSP OFF 
and the IF OFF.? I then adjust the DSP value for optimum results without 
it destroying the quality of the signal.? DO MAKE A NOTE OF THIS VALUE.? 
Then set the DSP back to OFF.? Then move to the IF and scroll through 
the settings in an effort to find optimum results.? Once this is done, 
leave the IF value as determined and return to the DSP and set it to the 
value previously determined.

This works for a given band and given type of noise.? Change bands or 
noise and do it all again.? There is no ONE setting correct for every 
condition. ? Right now my 6M noise buzz is S-7 with the NB off.? Then 
turning it ON and adjusted as above the 6M noise is S-3.? That's 4 S 
units or 24 dB improvement.? I doubt you will get much better than this.

As to Noise Reduction, I find it best performs for CW mode. Again it 
takes careful adjustment to obtain optimum results.?? I don't use NR for 
SSB signals. I prefer to adjust the Attenuation value and the RF Gain to 
produce optimum results when operating SSB.?? I find optimum results 
occur when the no signal band noise is about 10 dB above the receiver 
noise floor.?? In order to accomplish this operating point, one will 
need to use ATTENUATION and RF Gain reduction.?? More gain won't aid in 
receiving weak signals, but just the opposite, as the signal will pop 
out of the noise.

I generally find using either NB or NR, but not both, is the better way 
to operate.? I doubt there is anything wrong with your radio.? Most 
likely the result is more related to receiver setting parameters.

I have a similar issue with what is possibly the filthiest wall-wart in the country. Unfortunately, our equivalent of the FCC failed miserably to do anything to get it stopped, despite my offer to simply buy a new one and the dear lady who owns it wouldn?t let anyone in to check.

I am now using a directional LZ1AQ mag-loop setup, with one of the MFJ NR boxes and a BHI audio DSP and signals are bearable but not great.

When things are really bad, I resort to cheating and listen on one or other SDR via the Internet, where antennas are good and local noise is minimum. What surprises me is how good the NR is on them, particularly Hack Green. There may not be nearly as much noise as I hear on the K3S, but there must always be some and with very little ?fiddling? it will sound like a quality FM broadcast (as long as the audio itself is clean.

Lots of good advice here. A major problem with the K3 NB is the way it 
is described on screen and in the manual. There are two blankers, one 
ahead of the crystal roofing filters, one after them. Each has multiple 
tweaks. In contest conditions, I've found good noise reduction from 
using the one AFTER the roofing filter, and set for the greatest depth 
and shortest time. I THINK it's called the DSP Blanker.

Yes, by their nature, NBs will modulate signals by the noise.

Let's hope the NB in the K4 is better.

Mike,
Thanks for that and I do understand what you say about the possibilty of
the control algorithm getting confused by the slow ramp up of power. Last
week Rob at Elecraft Support had me using a 50 ohm dummy load with the KAT3
bypassed. Set PWR to 5.0 W and hold down XMIT to TUNE, this performs a Tx
gain calibration. Then set to 11.9 W and TUNE again. My results were 5W
immediately but rising from 8.4 to 9.8 W in about 6 seconds

Rob then had me checking WMTR LP setting in CONFIG menu (TECH MD ON). This
was set to the default value of 70 which he suggested I increase . (I'm not
at all sure what this is doing). Increasing this value to the maximum of
180 gave me 10 W increasing to 12.0 W in 2 seconds, faster but still quite
a delay.

This does happen on every TUNE button press but I don't have any problem
during my daily use of the rig on CW. I have not fired up my old Tektronix
scope yet to look at the keying envelope.

Elecraft Support have gone quiet this week so no further progress.

73 and thanks for your help,
Tom G3OLB

I find both the NB and NR on my K3 to be moderately underwhelming, not 
sure why.? Ignition noise used to predominate in urban and suburban 
areas and blankers like the one in the 75A4 were very effective.? I 
don't know what Detroit did, but I haven't heard ignition noise in 
years.? A general rule of thumb has always been to use blanking in wider 
bandwidths which sort of makes sense I guess ... the blanking pulses 
consume a smaller fraction of the overall signal passband.? My 
understanding of the K3 NR is that the DSP processor tries to build a 
matched filter around the signal on the fly.? It may be a bit too much 
for the algorithms, I've never had much success with it on broader noise 
such as power mains hash.? Backing off the RF gain seems to be more 
effective.

The best noise reduction I've ever encountered was on the receivers in 
the transportable AN/TRC-96 2.5 KW HF ISB system back in the 60's.? 3 
voice channels and 16 TTY channels on the 4th.? Don't remember the mfr 
and don't know how they did it but you could literally make noise 
disappear with minimal effects on the signals.

If you know what you're doing, it can be done in a minute or two. I 
managed to change my settings from optimized for 6M to optimized for the

Sadly, I must agree and this is probably the most glaring deficiency in
an otherwise stellar radio.  Fortunately, where I live now I am able to
control the noise for the most part unless the electric fence gets an
arc and then that needs to be tracked down anyway.

I had hopes that work on improving the NR would continue but it is
apparent the K3 is now an abandoned radio in league with many others.

On the K3 I use AFX BIN mode (stereo speakers) which really cuts the 
background noise to my perception.

Whatever other NR the K4 will have I hope there is an AFX binaural mode 
also.

 Have we, in fact, established that this attenuator is enabled at any point of the tune cycle? Because if not, then we're all spun up for nothing.
Is it reasonable to believe that the attenuator was one of those design elements that might have been deemed necessary at one time but then the designers changed their mind for the finished product?? I think so. The mysterious R7 may have been left off of the final circuit board precisely to cause such a bad mismatch that it would be obvious to operator, software, or both, and so that corrective action could be taken.

I have contested from several locations with noise issues and I have also
not been able to find a NB/NR setting on my K3S that offers any improvement.

For 12 years I've tried to get any enhancement of s/n from the K3 IF/RF

signal is modulated and degraded by nearby signals to the point where 
reception is better with NB/NR turned off.  As far as I can see, both of 
these features are useless on the K3 under contest conditions.

" Have we, in fact, established that this attenuator is enabled at any point of the tune cycle? Because if not, then we're all spun up for nothing."

KAT500 Serial Command Reference Revised 8/18/2021 firmware version 02.00 says:

"ATTN Enable Attenuator GET format: ATTN; SET/RESPONSE format: ATTN0; (disabled) or ATTN1; (enabled). Selects relay K22, which switches in an attenuator resistor. It may take a few milliseconds after issuing an ATTNx; setter before the relay changes. Firmware releases the attenuator if it detects power high enough to damage to the attenuator. Firmware normally inserts the attenuator during ?full search tune? to present a more consistent load to a transceiver during tune operations. The attenuator is disabled if the tune power is too low with the attenuator in place."

This version was released so the document was compatible with firmware 2.05 changes.

As I have said earlier in this thread I see no evidence that ATTN changes state during a "full search tune".

We are left with an attenuator design change that no one seems to understand and documentation that may not be correct.  Whether that is "spun up for nothing" probably depends on one's perspective.

I agree. I once suggested to Wayne that Elecraft charge something for
feature upgrades after a certain point in order to provide a revenue stream
to justify them. I received a chewing out unmatched since I got caught
driving a jeep without a helmet. This is not part of the Elecraft
philosophy.
As a result, like all the other manufacturers, there comes a time when the
answer has to be "buy a K4."

I've been wondering for some time if my 10-year-old K3's frequency 
calibration was off, because it seemed like most spots of me were well 
off when I clicked on them, usually in one direction.? Not having a 
frequency counter, I went to the alternative method outlined in page 49 
of the manual.? I thought I did it all "by the book", but found that 
when I was done 15-MHz WWV's carrier frequency (determined by 
zero-beating the carrier) was almost 400 Hz low. Since I wasn't looking 
for FMT-level accuracy, I went back to WWV and adjusted the REF CAL 
setting by ear until 15.000 on my RX dial was as close to zero-beat with 
WWV as I could tell. We'll see how it worked out, but I wonder if I 
simply have some fundamental misunderstanding of what's involved.? 
Wouldn't be the first time...

Hi Pete,

The WWV method worked for me until it didn?t.  On the advice of one of the K3 gurus, I am now using a Leo Bodnar frequency source.  Works great.

Snowy,

It sounds as though you have the proper BFO crystals installed at X3 and X4.

Do check the values of C173 and C174 first
Then check L33 to make certain it is well soldered and the leads are 
attached to the 1/8 watt resistor leads.
Check D37 and D38 to be certain they are oriented properly and well 
soldered.

Lastly, lift one side of L33 (and its resistor and remove the rubber pad 
- check the resistance of the pad itself - there were a few (a while 
ago) that were found to be conductive causing problems such as yours.? 
Since you did not state the vintage (or serial number of the K2), do 
that check if those items above do not correct the problem.

While you have the rubber pad out, make certain that about 1/2 of the 
stem has been cut away.? That is to allow the 1/8 watt resistor to be 
pushed down into the center of L33 to tighten the leads and hold L33 
securely in place.

If the rubber pad under L33 is found to be conductive, get a new one 
from Elecraft, or -- If you have an unassembled KAT2, you will find 
several of the rubber bumpers in that kit - a conductive one will work 
fine in the KAT2, but not in the BFO circuit.

Don W3FPR

Pete,

When using WWV to set the K3 reference, make certain you are listening 
to the carrier.? WWV is an AM signal that is modulated by a 500 or 600 
Hz tone on alternate minutes (440 Hz 2 minutes after the hour).? That 
produces tones that are both above and below the carrier.
So be certain you are hearing the carrier and not one of the modulating 
tones.

You had it fixed, but then you broke it again. After doing the 
alternative method on page 49, when you tune in to 10.0000 MHz in CW 
mode, you should hear a CW note at the same frequency as your PITCH 
selection.? I presume that is 400 Hz.

I got an extremely good score on last year's Frequency Measuring Test 
using only that alternative calibration method.

This is just a suggestion and forgive me if I?m not aware of something that
already exists. What if there was the annual event called the The Elecraft
NVIS field day?

As we all know Elecraft plays well with others, and along that theme
everybody would be welcome to participate  in such a field day event. I?m
guessing there would be a lot of KX twos and KX3 Yahoo Group all along with
several other QRP radios and some 100 watt ones. Who knows Wayne might put
a battery in a K4 and climb a hill.

I have never made it in VIS contact but for emergency preparedness and just
knowledge I would love to learn a lot about it and having others to
participate would make it even easier to perhaps relay a message to across
America

My understanding brief as it is is it 80 meters is one of the better bands
for NVIS

Perhaps designate different segments of the band for the 0-9 groups
depending on where you?re from that way you could listen in for your
neighboring groups

No stress, just good clean fun and an opportunity to learn.

Comments and suggestions welcome

Greg,

You might want to consider doing this within the Winter Field Day event.
There are 'indoor', 'outdoor' and 'home' categories.  The next event is Jan
29-30, 2022.  See www.winterfieldday.com for details.

I had fun operating the event in Jan 2021 from a portable beach house site
using a K3/100.  Due to a logging mistake on my part, my score did not get
reported.

There is a major myth regarding NVIS that antennas must be low. This is 
totally false. The facts are that vertical antennas are terrible for 
NVIS, and that horizontal antennas work better up to nearly one-half 
wavelength above ground. This study ran in National Contest Journal 
several years ago.

Wait, why would people think verticals are good for NVIS? Isn't a
vertical's radiation pattern pretty much "sideways but not up", and NVIS'
desired radiation pattern "up but not sideways"?

Message-ID: <B3FCB90C-6AFD-40F5-A79D-2081CC48EFFC@dremy.com>

When I key the mike, my friends hear a hum on my signal that is not there when I use the Heil Proset K2/K3.  I hear the same thing when I monitor my signal on the KX3.

I?ve checked the connections at both ends and do not see anything amiss.  At the mike end, the ground wire is ?floating? and not attached to any terminal like it is at the plug end.  I do not see any severed wire/s anywhere.

Any ideas would be most appreciated.

Thanks so much,

I find that trying to match two beat notes when I can only hear one at a 
time to be hard, best I can do is maybe 10 - 15 Hz Hz depending on the 
frequency.

FWIW:? The Burdick Calibration Method [BCM] for the K3 is actually much 
easier to perform than has been suggested in this thread,it is 
incredibly accurate, and it works for me every time. A couple of 
possibly helpful hints:

1.? The WWV signal is somewhat complex.? In addition to the carrier and 
AM voice announcements, it transmits tones, 500 Hz and 600 Hz on some 
but not all alternate minutes, and 440 Hz as an hour marker.? 
Additionally, a continuous time code in a slightly modified IRIG-H 
format is transmitted on a 100 Hz sub-carrier using both PWM and PM 
modulation.? The 500 and 600 Hz tones produce sidebands and it is very 
easy to attempt to zero beat one of those instead of the carrier, so 
choose the period :43 to :52 in each hour when there are no tones.

2.? Put the K3 into USB [or LSB], either will work fine.? Choose a time 
when at least one of the WWV frequencies is strong at your QTH.? Any WWV 
freq will work ... if you are OCD, 20 MHz may result in tiny 
improvements in calibration accuracy which you'll never notice in normal 
operation.

3.? Generally, wider DSP bandwidths will make the true zero beat more 
discernible so long as other adjacent signals are not present but it 
does depend on your hearing.

4.? Not all WWV frequencies are created equal.? If you have a P3, you 
can look at the spectrum of each of the signals.? For the 5, 10, and 15 
frequencies:? It appears these use 10 KW plate-modulated, transmitters, 
likely with Class C PA's and there is more distortion present than I 
expected from NIST/WWV. You can see the 100 Hz sub-carrier and the very 
close in sidebands from the IRIG-H time code, and the first sidebands of 
the 500/600 Hz tones.? Because of the distortion, the two 1st sidebands 
will be modulated by the 100 Hz sub-carrier and its sidebands.? You will 
also see the two sidebands from the 2nd harmonic of the tones at reduced 
level too, also modulated by the 100 Hz sub-carrier.? On 10 MHz, I can 
also see the 3rd harmonics of the tones clearly, and can sometimes make 
out the 4th.? It's a great demo of how to annoy your fellow hams with 
distortion in your transmitter. ?

The 2.5 and 20 MHz signals use 2.5 KW transmitters that are apparently 
much more linear.? They exhibit the carrier, sub-carrier and its 
sidebands, and only the fundamental sideband of the tones.? This will 
help a little in finding exact zero-beat, however a strong overall WWV 
signal with minimal QSB is way more important.

5. Set your K3 for 1 Hz display resolution.? You may want to experiment 
between high and low counts/revolution of the knob, I find lower 
counts/rev works better but YMMV.? Don your headphones, AF gain up 
almost to the point of uncomfortable, set the freq display to exactly 
the WWV freq.? Then, tap MENU->CONFIG and tune VFO B to select the REF 
CAL menu entry.? The display will show a long number. Mine is 49.379682

6.? Now the fun part.? Carefully adjust VFO A to achieve zero beat.? V e 
r y? s l o w l y rock VFO A through zero beat. The tone will get too low 
to hear, and as you go thru ZB, the background noise will begin to 
"pulse", fast at first and then slower, until you can count the 
amplitude pulses, and then begin to speed back up as you move to the 
other side of ZB.? You want the point where the pulses are the furthest 
apart.? In my K3, I can get down to about 1 pulse/2 sec and then 
continuing one encoder step, it goes up to 1 pulse/sec.? True ZB is 
between those two encoder steps, I set mine to 1 pulse every 2 sec. Tap 
MENU, and call CQ on exactly the frequency of your choice.

You can switch between USB and LSB after you've found your ZB spot, it 
just inverts the process.? The whole BCM takes way longer to describe 
than to do.? I've run it a few times over the years and my K3 [S/N 642] 
has never varied more than about 4 Hz in that long Ref Cal number.

It is absolutely true that antennas intended for NVIS use do not have to be hung low.  But they CAN be.  And there are instances where doing so can be desirable.

When I lived in Hawaii, we used NVIS for reliable statewide HF communications to very good effect.  When I hung my dipole up about 30 feet or so, I would frequently get calls from hams in Japan, Oceana, mainland US, Canada and elsewhere. Ordinarily that would be nice, but when one is specifically focused on local comms, that can get to be a problem. When I hung my NVIS dipole down around 10 feet, I still got excellent statewide communications but no longer got calls from afar.

So I kept my dipole low for local, and erected a vertical for DX.  Both worked perfectly for their intended use.

In Hawaii, 40 meters worked great for NVIS probably 11 out of 12 months a year. Someone else who knows can comment, but I got the impression that 40 meters almost never works for NVIS in the mainland US.  If this is true, an Elecraft NVIS field day might be limited to those who either have room for an 80 meter dipole, or who can devise some other kind of 80 meter antenna that can radiate up.

--- "In Hawaii, 40 meters worked great for NVIS probably 11 out of 12
months a year. Someone else who knows can comment, but I got the impression
that 40 meters almost never works for NVIS in the mainland US.  If this is
true, an Elecraft NVIS field day might be limited to those who either have
room for an 80 meter dipole, or who can devise some other kind of 80 meter
antenna that can radiate up."


I think it depends on time of day, time of year, and what part of the
sunspot cycle.  40m is pretty much the top limit for NVIS though.  But
sometimes 40 works for NVIS.  That's one of the reasons for our 60m
allocation, NVIS when 40 is too  long and 80m is dead.   OTOH  I've seen
160 too long for statewide coverage at times.

FWIW, I agree a vertical is not an NVIS antenna.  Some people may be
confusing groundwave (usually up to 25 miles) with NVIS.  They are totally
different propagation modes.

Yes, AND groundwave weakens drastically with increasing frequency. With 
average soil, a station operating on 550 kHz will be 21 dB stronger at 
100 miles than a station running the same power than one operating on 
1600 kHz, assuming both are using a single quarter wave tower.

I put up an NVIS antenna for 80m a number of years ago.? It works great 
for local 80m nets.
It is a full wave length loop (more square) mounted about 10' above the 
ground.
It is feed with 450 ohm ladderline from a 1:1 current balun at the ATU.
EZNEC shows the radiation is UP.
It also shows gain and not as much UP on 40m and 20m.
I have worked DX on all bands.

For 80M NVIS I put up a 'improved' extended double Zepp (315' long 
designed by N6LF) at 30' with a wire reflector 5% longer buried an inch 
in the ground. There is a 4:1 balun at the center with a coax feedline 
to the shack. Covers entire band under 2:1 SWR. Email for more details 
if desired.

Subject: [Elecraft] TX EQ issue
Message-ID: <0B.D2.09316.5831EB16@smtp03.aqua.bos.sync.lan>

Having trouble setting TX-EQ for FM and SSB.  Changing TX EQ when setting TX EQ in FM mode,  the TX EQ setting for SSB changes to what was set when in the FM mode.  This feature appears to not be working.

Manual says two separate EQ settins are available ,, one for SSB, a second for AM/FM modes.

Filter TX set-up.

FL1  - 13KHz -- set for FM TX
FL2  - 6KHz  set for AM TX
FL3 ? 2.8KHz ? set for SSB / CW-DATA  TX

Has anyone else observed this issue?

Solution?

>You might want to consider doing this within the Winter Field Day event.

That's a great suggestion.

Those are correct who say that an antenna (dipole) doesn't have to be low
to the ground to make use of NVIS - but having a low antenna goes a long
way toward limiting the contacts you make to NVIS propagation.

I suspect you could accomplish the same result simply by reducing 
transmitter power.

A dipole 1/4 wavelength high has a nearly identical radiation pattern to 
one close to the ground.? It just has less loss.

My K2 PLL problems all originated in one inadequately tinned toroid wire. I have successfully built a fair number of kits with toroids, but it is pretty easy to end up with a lead that is not actually connected. Even though it looks good.

So that is where I would start, check for continuity on every single toroid.

I'm about 25 km LOS from W7RN.? W7RN is 30 over S9 here on 160, 10 over 
on 80, about S7 on 40 anytime.? I can barely see it on the P3 [and it's 
QRK2 in the noise on the headphones] on 20, and missing above 20.? K2RD 
in SW Reno is a bit closer, but the same prevails for the ground wave 
for Ira.

NVIS information is almost always anecdotal and a myth, more than science!
As I have told many participants in many presentations, "If you think
lowering your antenna will make your signal stronger, expect your QSL cards
to arrive on a unicorn."  How many of you looked at Jim's, K9YC,
explanation?  Probably too few.

40m is near the upper limit of NVIS and currently, it is often below the
NVIS frequency.  At this point in Cycle 25, I frequently can't copy
stations within 150-250 miles away on 40m here in NM.  The ones I copy best
have the highest, NOT lowest, antennas.

Note, as shown in Jim's paper, an 80m dipole at 60 ft. provides the maximum
NVIS signal while at one at 90 ft. is just 1 dB down.  Having operated with
an 80m dipole at 75 ft. on an Air Force RADAR site, my 100 Watt signal was
almost always stronger than those with lower antennas around MI.  Yes, that
is anecdotal, but it agrees with the science as modeled in Jim's paper.

I have yet to read of anyone's scientific data showing their 10 ft. high
dipole worked better than their 30 ft. high dipole on 40m, to say nothing
of similar 80m dipoles.  If you have two WSPR transmitters and have
antennas at these heights, gather some data.  Both transmitters must
transmit the same level signals at the same time over time to collect
meaningful data, assuming everything is equal.

I once worked a station in Italy on 20m SSB with my KX3 using my mobile
antenna.  I did not replace much better antennas at home based on that
anecdote.  Neither have I received any QSL cards on unicorns although I do
have a unicorn graphic in some of my antenna presentations.

The method I use seems to work great and be easy enough to do. No zero 
beating required and no external measurements required.

Put the radio in CW mode, tune to a WWV frequency and press and release 
SPOT.? The radio will automatically zero to the carrier with a tone that 
matches your preferred CW note.? Then via the CONFIG MENU go to REF CAL 
and adjust up or down with the VFO A knob,? the number of Hz error the 
previous SPOT routine disclosed. ? A 10 Hz change on the REF CAL will 
equate to about 2 Hz at 10 MHz.? ? I find that checking several 
different WWV frequencies is even better using this method.?? To make 
sure it is optimum, tune to 5 or 10 Hz above and below each of the WWV 
frequencies.? Press SPOT from both above and below and see how it 
resolves.?? Usually I can get within 2 Hz or better on all of them.? You 
may need to do this several times.? Be sure the radio has been on for at 
least 1/2 hour to allow things to stabilize.

Just a comment on low dipoles:

On the Iditarod Dog Sled Race (Alaska) we had ham stations located in 
remote located checkpoints (total bush-no telephone or other utilities). 
  We used 80m and 40m to communicate with race HQ in Anchorage over 
paths of a couple hundred miles to 600 miles, or so.

80m worked well at night and 40m during the daytime.

Since one packed their station in a couple boxes to be hauled in small 
airplanes to these remote locations, antenna was a simple 80m wire 
dipole with clip-out sections to convert to 40m.

Usually antennas got strung from trees or buildings only high as one 
could reach or maybe using a stepladder.  They were NVIS by definition.

I recall some hung only 8 to 12 foot high, yet they worked fine with 
100w.  Not every station could reach HQ so quite a bit of relaying race 
traffic was done (reporting times in/out of checkpoints).  The race 
extends 1100 miles over a 8 to 20-day period as the dog teams varied in 
speed.

Ham radio is no longer used as the officials went to using sat-phones. 
But I was lucky to go out eight years on the trail as ham operator in 
the 1980's.  Used barefoot TS-180S and dipole (plus 600w Honda Gen).

You never lived until you slept in a wall tent at -60F outside (and -15F 
inside the tent).  Radio worked but LCD display took a little time to 
start when cold.

I?ve scanned back through this thread and I don?t see where anyone said that their signal got stronger by lowering their antenna.  Maybe I missed it somewhere?

To be clear, in my specific case, I was crafting a purpose-driven antenna. I wanted an antenna that would provide reliable, continuous coverage over about a 400+ mile radius. I did not want to hear, or be heard by, anything or anyone outside of that area. I didn?t care about efficiency, QSL cards or anything else, mythical or otherwise.  Putting a dipole at about 10 feet (plus or minus, I don?t recall the exact height) accomplished everything I wanted. I worked, on a daily basis, hams at all points along the length of the State of Hawaii, I experienced reduced band noise, and I did not have to contend with stations outside of this area. Problems solved. I don?t think any of this contradicts science.

Believing that the antenna MUST be low for NVIS DOES contradict science. 
As my extensive study, which has been peer reviewed, shows, all that 
having an antenna very low does is increase loss, making your signal 
weaker, and make distant signals weaker in your receiver.

I agree. I never said, believed or thought an NVIS antenna HAD to be low, I just said it COULD be low.  

In fact I was banking on the fact that making it low would make distant signals weaker.  ;-)

Hi Wayne,

After searching I found info in the programmers manual that helped me understand how it works.  It is a little hard to follow using the K3 / K3S owners manual, and / or Cady?s book.

I have written a couple of macros, not yet checked out, that may work(?).  


Turn ESSB ON, SET TX EQ:
	ES1;TE-03+00+00+00+00+00+03+03;	Mode must be SSB to turn ESSB ON, SET TX EQ Bins, 
						Sets EQ for ESSB (USB, LSB), AM, and FM
						A ?+? sign will appear in lower RH corner of display
Turn ESSB OFF, SET TX EQ:
	ES0;TE-03+00+00+00+00+00-03-06;	Turn ESSB OFF, SET TX EQ Bins for current mode Two 
       Separate TX EQ, 1,(USB, LSB) or 2,(AM FM)

Also I was able to effect the settings via the Main/Config menus?. Setting ESSB ON a single TX EQ is used for all voice modes.  Setting ESSB OFF, the two TX EQ settings will be be available as described in the macro notes.  I haven?t verified this with testing yet as to the actual effect?

Also, not sure about the CW/DATA Modes?.. I don?t see a macro command for that, but it is stated that CW/DATA TX-EQ is set ?0?.

Separate TX EQ for different voice modes has not yet been implemented. I'll make sure it's on the list.

Not sure why nobody has mentioned using WSJT in frequency calibration mode. It?s the bottom selection in the Mode menu. Shows  your offset in Hz to about 5 decimal places. Just pick from the list of standard freqs and away it goes. Then adjust the K3 ref frequency to walk it in. There are even guys doing long-term observations on Allen variance this way.?

After exchanging emails with N4ZR, who started this thread, we think 
this is the easiest procedure:

Tune the rig to 10.000 MHz in CW mode.? Listen to the tone of the WWV 
carrier, which should be close to your CW PITCH setting.
Switch back and forth between reverse cw and normal cw, adjusting REF 
CAL until the tones are equal in pitch on normal and reverse.

This procedure should get you calibrated well within 1 Hz, much better 
than required for any amateur radio application that I can think of.

Message-ID: <1BBC7D1A-DE3D-4F34-89F2-606EEE5834F1@elecraft.com>

We traced this (on Saturday, because it's not just a job, it's a lifestyle :) to incorrect AF gain scaling with some combinations of AGC threshold and slope. The fix should be in the next beta release, possibly as early as this coming week.

Prior to this fix, as some K4 users observed, the max AF you could get into a 4 ohm speaker with AGC threshold = 4 and slope = 15 with an S9 signal was about 150 mW. Now it's in excess of 1.5 W with any combination of AGC settings. Into an 8 ohm speaker it's about 1 W, meeting the proposed criteria. 

The upshot is that even with the lowest threshold setting--the one that levels the audio most aggressively--you won't be lacking for AF output at the speaker, phones, or line out.

We'll be updating the spec as well. It should have used 1 W as the reference level rather than 2 W.

A quick update on another request: we're adding new narrow CW filters with much steeper skirts. This will apply to filter settings of 200 Hz and narrower. You be able to select the original narrow filter shape using a menu entry, if desired.

Take a look at Dean Straws NVIS article (with color graphics) in the
December 2005 issue of QST for a discussion of optimizing antenna height
for NVIS based on signal to noise ratio and region you wish to cover.  Most
if not all of that article appears in the 23rd and 24th editions of the

Thanks Jim.

I was glad that Dean deviated from the usual zero dB reference style of
many ARRL antenna patterns and addressed NVIS propagation for the EmComm
(Emergency Communications) audience with signal levels over geographic
regions and graphs with your style of everything plotted on the same graph
such as in fig. 3 for easy comparison.

He provided frequency choice guidance for both high and low solar activity
periods for nighttime and daytime propagation, as well as clear portable
and home / base station antenna height recommendations. It was a basic HF
NVIS cookbook for field EmComm operations antennas.

In addition, I installed the "Keuwlsoft Audio Frequency Counter" app on
my Android phone and set it next to the speaker.  Its display in Hertz
makes dialing in the reference calibration value quick and easy.  On my
K3 it shows about .5 Hz difference between Norm and Rev.  I certainly
cannot hear that!

I use WSJTX but not in its CAL mode.  Simply set the VFO for x.000 on
the highest frequency you can reliably hear WWV (10, 15, 20 or 25 MHz)
and "dial in" the audio tone (SSB or DATA A) to the proper 500/600 Hz
frequency using REF CAL.

I've stopped using the "toggle between USB/LSB or CW/CW_R" and match
the tone as it's far easier to set the trace on the waterfall -
particularly if one sets "bins per pixel" to 1.

Thanks to Bill Parsons-AF6AE for the tip on the QST December-2005 
article.  Pulled it out and scanned it over (will read more thoroughly 
later) but interestingly showed how 80/40m coverage varied by time of 
day (which was demonstrated real-time in the 1980's on the Iditarod 
trail working into Anchorage).

At home I only use those bands infrequently and mostly to talk out a few 
hundred miles in Alaska.  Somewhere I read that a 40-foot high 
inverted-V would work well.  I have a 50-foot tower mounted to end of my 
house with Hygain TH3mk4 tribander at tower top so hung my 80/40m fan 
dipole at the 40-foot level with end tapering down to 20-foot on one end 
and 15-foot on the other.  Its hung on a line NW to SE but that seems to 
work out 400 miles just fine.

I am going to re-hang that antenna next summer with 80m wire at right 
angle to 40m wire as the fan-style 40m tuning was affected by proximity 
of the 80m wire.  As I have written previously, I will also run this as 
a top-hat loaded vertical on 160m/630m by shorting the 40-foot high 
feedline.

I check into a weekly net on Saturdays (11am local time) on 3920 KHz. 
NC is about 70 miles south in Homer, AK (KL7PM) and consistently comes 
in at 30-40 dB over S9.  He does run about 400w.  I get at least S9 
reports from him with my 100w and I hear other stations out as far north 
as Fairbanks (400 miles) pretty well.  Band noise runs S7 (K3 PRE Off).

3920 is designated emergency channel for AK and often activated after an 
earthquake for tsunami watch.

Exactly....

When I was first licensed in 1971, a guy up the street waxed poetic about 1957, when he used an 11 meter AM walkie-talkie to work VK while standing in his front yard in San Diego. This was the vision that eventually led to the KX3, and later the KX2, which is half the size/weight, more like the all-band HT I couldn't quite build in high school :)

Good Evening Don
Sorry for the late reply, not used to the format of the reflector and stumbled onto your suggestions to solve my BFO problem.
I am please to say that I have now got it working correctly.
Getting nowhere with the test I decided to dismantle the radio down to just the RF board, removed a surplus of solder from the D36/37 area, re-flowed the pins of U10, lifted the leg of the 5.1meg resistor and L33, didn?t know about the rubber bung being conductive however once again removed a surplus of solder from that area, I also added a small cut of insulation tape to form a bed for the resistor on L33, thinking that turns may be shorted, at this point I ought to explain I purchased this as a built but non worker, it is an early radio as it has a Rev A mother-board with a small pot for R60 and an early control board with the 12v switch rather than the berg connectors, I have built 5 or 6 of these for people and never had a problem certainly not as many faults as this one appears to have had, there is no serial number on the radio, but it has had the PLL thermistor conversion as well as the D36 done.
Have to thank Dave for sticking with me on this one, without his guidance I would still be trying to sort the PLL problem.

Have a good Christmas and New Year 2022

That Keuwlsoft Audio Frequency Counter is pretty cool!? Thanks for 
pointing it out.

I found the easiest way to use it is to put the K3 in reverse CW, tune 
to 10.000000 MHz, and set REF CAL to a setting that "eyeball averages" 
best to your PITCH setting.? Even with the eyeball averaging, it is 
pretty obvious which REF CAL setting is best. Use reverse CW, because if 
you rotate REF CAL to the right, the pitch will increase, so it is more 
intuitive than normal CW.

I will use this as my go-to cal procedure.

style end fed random wire thrown over a tree.? Using AWG 14 but need a 
smaller wire.? Anyone have a favorite wire you use for the Ant and

One of these messages talked about 20+ years ago at the peak of cycle 25.
I remember 64 years ago with a DX100B, 4 el yagi at 70 feet and BC348 with
a Gonset 10M converter for receive.  I was king of the bands, working the
world and every TV set in the county.  I'm not sure my parents even
mentioned it to me.  Only many years later did they tell me.  Obviously,
they were very supportive of their budding engineer. I am grateful.

It is super slick.  I typically have it on a winder with a strap or hair tie to keep it together.

Stranded?26 awg PFTE or other slick coated wire has worked very well for both antennas & ground plane(s). I bought a military?surplus spool of PFTE years ago off Ebay. Great stuff.?

Supportive parents are great but?tolerant XYLs are better. Back in the heyday running a linear on 40m, I would flash lights, open the garage, screw up the stereo and Tv in the house. Wife would smile and say to back off a bit! Now that?s awesome? Now if I can?t get it done QRP,?100w is the?max for me!

Message-ID: <6cae192a-16ca-401d-c09e-215d3fa33a37@gmail.com>


Due to some HOA C&R, I am confined to attic and gutter antennas for the 
time being.

I am getting a bit of RFI on occasion into my PC; it manifests itself 
mainly by apparently disconnecting the com port from Commander.? When 
this happens, I can restore functionality by selecting a different com 
port, and then re-selecting the original correct com port.

I am grounded to a 10' ground rod about 8 ft. from the station via 2" 
copper strap. I did install ferrite beads on the USB cables at the back 
of the PC as well as on the power cord, and this has reduced the 
frequency of occurrence, but I would like to eliminate it altogether.

Any other ideas and suggestions would be most appreciated!

Thanks & 73 de Dave, W5SV

Bond the computer case and radio with strap.? That provides an alternate 
path for RF reducing the amount on the USB cable.

The fact that clamp-ons reduced but didn't cure is a good sign.? A few 
turns thru ferrite toroids are ever so much more effective than the 
clamp-ons which I think is what you mean by "beads."? Mix 31 is best for 
HF, but 43 will also work well.? USB cables with an A-connector on one 
end and a B on the other will support 3 or 4 turns on a 1 1/2" toroid if 
you wind it using the B-end.? The finally wound toroid should be placed 
at the end of the cable connected to the device experiencing the RFI.? 
Larger clamp-ons will often let you get two passes thru the ferrite for 
thicker power cords.? Common mode chokes are usually placed at the feed 
point of the antenna, but there are times when one on the coax at the 
rig will reduce RFI also.? And, don't forget any audio, keyboard, or 
mouse cables.? Visit k9yc.com for more exact, specific research on every 
choke known to humankind. ?

Yea, back in 1959 as a novice, I worked all over EU with a DX-20 and a
single wire antenna. Yes, I could also hear the TV two doors down and the
little old lady screaming at the screen. I don't think she really
understood the source (her unshielded TV tuner) and maybe a little harmonic
RF from me.

I third the selection of ?The Wireman? products.  Excellent quality.  I use the 26-ga myself.

When we moved to this QTH about 20 years ago my wife (SWMBO) remarked on how the location was perfect for ham radio as we are on top of a smallish hill.   So. Much. Win.  Or so I thought. 

Years later when I had the temerity to launch an OCF dipole across two trees, the first words out of her mouth were ?What is THAT POS??   

Obviously she didn?t have the same mental
Image as I did.   I quietly filed the tower plans and am now QRP mobile.

   I have a similar situation. Our CC&R's prohibit any and all antennas.  
Period.

   Here's how I dealt with it.  I ran for the Board.  Have been serving
for 10 years.  Last year I got my 6BTV approved by the Board - in 
WRITING.

   Every two weeks I host a town hall on zoom for the entire HOA 
membership.
For those meetings, I change the location of the webcam, so my station 
is
not visible.  :)

   A tower & beam are probably not politically feasible;  but I'm happy 
with my
vertical.  I even tossed the ancient flea-market one and installed a 
brand new
one from DX Engineering, along with their tilt base.

The 24ga speaker wire is tougher, inexpensive and available locally.  Postage for long distance orders would be more than the wire itself.

I?m just sayin??

Good Evening,

 ?? Each day the rain melts the snow.? Each night the snow returns.? 
This has continued for about two weeks.? Last night the cycling ate my 
doublet.? It must have broken early because when I saw it this morning 
the hanging wire was coated with an inch of snow.? The snow loads the 
fir tree's branches, which causes them to droop, sometimes from 
horizontal to a few degrees from the axis of the tree.? 14 gauge THHN is 
pretty sturdy, it can last for a few winters.? Now it will become radial 
stock.? This antenna must be around five years old, some kind of record :)

 ? Signals were good to great on both bands.? Twenty meters was very 
quiet.? Then I received my first response and turned down the gain.? 
Some slow QSB on folks east of the Mississippi.? The QSB on Roy's signal 
from Iowa was strange.? It sounded like chirp but that affects each 
element of each character.? This "chirped" parts of words.? The QSB was 
not chopping up the characters, it was slower than that rate.? But it 
modulated the tone of characters over the span of a word.? Very odd.? 
The sun is definitely giving our ionosphere a deep massage.

 ?? I would like the present propagation conditions to continue :)

Snowy,

I am glad to hear that it is now working for you.? It sounds like you 
had a soldering problem somewhere.
A surplus of solder usually means that the lead and solder pad were not 
heated sufficiently.
If you have other areas where you find excess solder, just reheat and if 
necessary, wick away the excess - you may have a fully functional K2 
sooner than you think.

It sounds as though some (or perhaps all) of the K2 A to B mods were 
installed in an attempt to get it working.
Which of the group of mods is installed is important to keeping track of 
the level of the K2.
You may want to download the K2ATOB instructions and all the other mod 
instructions to do a physical check of the installed components.? 
Knowing the level of mods installed is important when chasing problems.? 
Make a log of the A to B mods installed for future reference.? The? 
level of the IF crystals? on the RF board and the KSB2 option is also 
important to having a good filter response - those crystals should be 
marked with a "-S" suffix.K2s above SN 2560 have the new crystals.

If the wiring mod for the sidetone source with firmware 2.04 has not 
been installed, do it.? It is required for the
KIO2 or the KPA100 (see the instructions for those options) .? If you 
have MCU 2.04r firmware it is mandatory? - you will not have sidetone 
without it.? If your firmware is 2.04P or earlier set the menu sidetone 
to U4-8.

73 - Merry Christmas and Happy New Year,
Don W3FPR

Same issue here - our CC&Rs specifically say no outdoor antennas

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

of your issues at the following web addresses:

Very good coverage of antenna and transmission line optimization to

Beat me to it. This is the 26 AWG. Breaking strength is 25 pounds, though I?ve never broken it.

For my 53 foot wire, I use the 18 AWG, also light, but with a breaking strength of 125 pounds.

Well Rich,

Guess you are a late comer.

I got my ham license at age 14 and I am now 77.  I've been married 18 
years.  She was married to ham before me, so had been "broke-in" before 
getting "saddled" with me (western sayin).  That was the good news and 
the bad news.

When she arrived north to live with me, I already had a 50-foot tower up 
and 8-foot dish inside a "golfball" radome.  She wanted a nicer home but 
knew there were two requirements: room for my 13 sled dogs and room for 
my antennas (and ham shack).  Now I have four towers and a 16-foot dish. 
  All the sled dogs have passed onto "dog heaven" and only have one 
house dog which is hers.

She knows the money goes into ham stuff and not beers at the local pub 
(plus skirt chasing).

And she is even the NA sales rep for Dubus Magazine (which she gets a 
little 'pin' money from).  Dubus is published in Germany and is VHF/mw 
ham technical magazine + European VHF activity news.  She even has 
accompanied me to ham conferences.

She is not a ham.  But she is a good one and I'm keeping her!

Elecraft K3/100 160-6m Transceiver Serial #2502 with the standard 2.7 kHz
filter, the KAT3 Internal Auto Antenna Tuner, KPA100W Amplifier and XRX3
Subreceiver.  The subreceiver is identical to the main receiver and has its
own 400Hz filter. It can tune the same range of frequencies as the main
receiver and is terrific at busting DX pileups.

   - This K3 also comes with lots of extras including:
   - Three (3) additional CW Filters: 700Hz, 400Hz and 250Hz for the utmost
   in selectivity.
   - KXV3A Interface Option which provides a separate receive antenna input
   and output, an input and output for use with an external transverter, and a
   buffered i.f. output. (Handy for adding an external Panadapter or SDR).
   - The K3 has been upgraded with the KSYN3A synthesizers in both the Main
   and Subreceiver. The synthesizer produces cleaner synthesized signals
   leading to better transmitter and receiver performance and has a better
   switch time to improve TX/RX switching for high speed CW.
   - There is no internal sound card in this K3, but included in this
   bundle is the TigerTronics Signal Link USB interface which adds an external
   sound card and comes with the Elecraft connection cable and complete
   documentation. Just what you need to work the new digital modes such as FT8.
   - You can connect a PC that has a serial port to download firmware and
   software upgrades as well as to allow computer control of the K3 with your
   favorite contest and general loggers. No serial port? No problem?I include
   the original Elecraft KUSB Universal Serial Bus Adapter cable which allows
   you to simply plug the K3 into an available USB port.
   - This K3 was upgraded, calibrated and aligned by the Elecraft Factory
   in 2015 to meet or exceed all factory specifications.
   - The installation and operation manuals are included as well as all
   upgrade and repair documentation.
   - This unit is sold *AS IS *and subject to the following *caveat* which
   may or may not be of concern to you: I am unable to get my Begali Single
   Lever Paddle to work properly with the Elecraft Internal Keyer. I can only
   send dits or dahs (depending on the menu option) but not both. In other
   words one side of the paddle does not work. There may be a problem with the
   paddle jack connection. I have always preferred to use either a straight
   key or my external Winkeyer USB as it performs well with the software
   programs that I use and it plugs directly into the Key Jack which works
   fine.


I am asking $1,695 for this package + Shipping via Priority US Mail to
CONUS.

I have been using a couple of "things"...

First see: 
https://www.amazon.com/Coghlans-Camp-Laundry-Reel-21-Foot/dp/B001QBZM4Q/ref=sr_1_29?crid=3GJ5K4I006OGB&keywords=camping+clothesline&qid=1640011049&sprefix=camping+clothesline%2Caps%2C109&sr=8-29 
as a wire winder.

I use 24ga Teflon wire.? The copper strands are silver plated, with a 
banana plug attached.? I have been using the winder + Teflon wire for 
many years.? Works great.

For my 135' ladderline fed dipole, I use 24ga silver plated wire that is 
(I think) nylon coated.? I picked it out of the "junk box" (trash) at 
work YEARS ago.? The closest replacement would be Teflon wire.? The 
silver plating makes for GREAT conduction.

Otherwise, I would use Wireman stealth wire either 26ga or 18ga.

Here's another, utterly impractical, solution:

When my wife and I built our weekend home in the Colorado mountains we chose
the site for its natural beauty.  Antennas are unnatural.  I was content
with having only dipoles and Vees, but even they spoiled the view.  So,
every time we were at the house and I wanted to operate, I would raise them
up.  When done, I lowered them, leaving the supporting ropes dangling
against their trees with a snap-bolt on each rope's end.  The dipoles
themselves -- including a multi-band for 10-15-20 and, at the time, Vees for
40 and 80 -- were rolled up, the coax feed lines were disconnected from the
sockets under the deck of the house, and it was all put away out of sight.

I no longer do that, and haven't in recent years given age and a bad
shoulder.  But during the first few years I learned how to deploy and store
my farm in minutes.

Hi All
Update on the K2 and its problems or now lack of them.
Finished setting up the filters and other than getting ?low Batt? indication now and again all appears to be well.
Fitted the KAF2 and set up the clock, that taxed my grey cell but managed it in the end.
Just need to give it an on air test and that?s it, sorted. 
Just want to thank Dave and Don for their help in getting me to this point.
 Thanks very much

*** After having a few projects borked because of this exact issue, I 
broke
down and bought a magnet wire stripper on Amazon.

https://www.amazon.com/gp/product/B09695CHTH

   Basically a Chinese copy of a really expensive German tool.  It has 
blades that
close down on the wire with centripetal force.  Works great for thicker 
wires,
but is not reliable with really thin ones - it can just chop the wire 
off.  I seem
to remember the cutoff being around 24AWG.

    The tool paid for itself on one KW Low Pass Filter project.

Hi,

Purchase some FT240-31 ferrite cores, 
(https://www.farnell.com/datasheets/1912768.pdf), and wind at least 5 
turns of each cable going to, or from, the computer through the ferrite.

I have several of these, and they stopped ALL of my RFI issues with my 
computer, and with a weather station I have as well.

Shop around looking for the best price, some folks are asking 10 bucks 
for one of these, others are asking 5 bucks...  I use Newark, and 
Digikey as my goto places.

Also look to K9YC's site, for more information on how to make the chokes...

Hello Elecraft List

Some guys were sending .jpeg's back and forth on 80m this morning and I asked them what program they used.

All were using EasyPal from EasyPal.org (free)  .

So I received several pix from the group but was never able to transmit.

The Setup mernu has a few rigs to chose from but not a single Elecraft.

Anyone ever used a K3 with that program?

Years ago...about 30, I had 2 ele 40, th7 and th5 and Higain Hightower and
double extended zepp ladder line fed cut for 40 which I used for 160-40.
Jobs change and that really changes one's life. I started traveling and as
such could no longer maintain the 3 towers so down it came all the radios
antennas and towers were sold. 23 years later, only being home for 1 month
a year, I finally retired. In the meantime, we sold the 2 story house on
the highest point in the city, and bought a ranch about 300 feet lower
surrounded by trees and hills with no view of the horizon in any direction
from the ground. Well a man has got to have something to do. My wife spent
disposable income on remodeling the house room to room. New kitchen, 3 new
bathrooms, walls were moved or taken down and space opened up. Everytime I
came home for a weekend, something had changed. And of course, each room
needed new furniture. Upon retiring, I told her I was putting up a tower. I
bought a Tashian 52 footer with a motor, and the arguments began...which
later changed to many heated discussions. Finally, a compromise was made. I
told her, I was perfectly content with not having ham radio with towers and
that I was going to buy a new $18,000 motorcycle and I would come home
maybe 6 months a year. I started getting my bike ready for trade in and she
started softening up after a few road trips when I was gone for a few days.
Then I went to Alaska for 21 days and 10,000 miles solo on my bike. I did
not miss the radio at all. It was a great time. When I got back she agreed
to compromise, especially when she saw me maping out 4 corners, Nova
Scotia, PEI, Iceland and Europe. A compromise was quickly made. I put up a
tower and bracketed it to the house. All approved by the city engineer and
building permits were obtained. I have a 38 foot Rohn 45G tower with
Navassa 5 antenna and an inverted L/vertical in the backyard for 160/80/40.
The entire antenna farm is 68 linear feet. As I have gotten older that is
all that I want and want to maintain. It is a pretty bombproof setup and is
easy to climb. During contests I put up other antennas for experimentation
in the front yard. I take them down after the contest. If I get complaints,
I just go out to the garage and start the motorcycle for a few minutes and
that pretty much ends the conversation.

I wish you well in your antenna endeavors. LOL!

I'm partial to the Kev-Flex kevlar core wire sold by Dave Cripe Nm0s. It's
small in diameter, wicked strong, and the PVC jacket is slick as snot on a
doorknob.  I but mine from him on eBay. He usually sells it in 75 foot
lengths, but if you want a longer piece, just drop a note in the order and
he'll leave multiple lengths in one piece.

I was using the Coghlan?s laundy reels, but it took a long time to wind up the wire, they would bind (not smooth turning), and would pop open when dropped. 

Now I use the Midi Winders from SOTAbeams. Wind the wire on in a figue-8, no kinks and quck to get on and off. SOTAbeams makes three sizes. The Midi Winders are the same length as my KX3.

It should be noted that the SSB 80M net has had some issues 
fitting in. We share a frequency with a net that's been active 
for over 35 years which runs on local (daylight savings) time. 
So we are at 0100z during the summer and 0200z during the 
winter. Yesterday, we had a lot of interference from stations on 
3.774 and moved to 3.783 which was open. If you want to check 
into that gabfest, look around. Or let any of the net controls 
know you are planning to checkin by Sunday morning and we will 
try to find you, either on-air or on-line, to get you to the net.

Hello Gwen Patton:

>?Sounds like a slow-scan TV program, but it's not. You upload the picture to

Well, it seems it does both ,,,,, sends (Hybrid) to a server; and sends OTA

This morning they were sending; I was rx'ing. I could hear the transmission over the K3.
Yet they guided me to a setting to put in the free, and original one, server over the internet.

And just now, I tested the length of time it took to send a pict of my 80m NVIS DP at ten feet above ground.

Took about 70 seconds. And I know I was sending over the air as the watt-meter was telling me so.

So that's weird!. why the program was designed to to both I dunno. But it surely does.

I have Yoniq too.



many thanks for the reply and help.

Snowy,

Make sure the switch on the Control Board is in the INT position.
If using a battery, it may have a low voltage - it must be higher than 
10.5 volts.

They're not very similar, they're identical! There's literally a website
address on the SOTAbeams winder I got from DX Engineering that goes to a
place that sells kite winders.

Sounds like a slow-scan TV program, but it's not. You upload the picture to
a server, then send the URL over the air for the other person to click on.
It has been around for a while, and there were claims it violated the
"pecuniary interest" clause in the regulations, but the hams don't get
money for it, so I don't think that's strictly so. I don't see any reason
why you couldn't use it, but I think it's more fun to use actual Slow-Scan
TV programs.

You can get MMSSTV, a venerable and last I heard, functional program.
https://hamsoft.ca/pages/mmsstv.php for free.

You can also get an SSTV program that ARRL links to, called Yoniq, a new
version of MMSSTV, which is also free.
http://www.arrl.org/news/new-sstv-software-now-available

This is yet another Internet/Amateur Radio fusion thing. I probably
wouldn't use it, though I do use a ThumbDV to access DMR, DStar, and Fusion
via my home computer and network. So I can't say anything bad about it
without hanging the "hypocrite" sign around my neck. hi hi

Hi,
	Having difficulty loading latest version of the Kat500 utility.  The version I have is 01.75, the utility indicates that 2.05 is available.  However the new version does not load but the message ? Input hex file is corrupt, check sum is not zero?

I have the same issue attempting to load a Mac and Linux.

Perhaps 2.05 is not available?  Or is there a fix I am not aware of, or perhaps it is not necessary to upgrade?

Thank you for your interest. Help would be appreciated.

For those using the clamp-on ferrite devices, when installing them, be 
sure part A closes completely and solidly contacts part B.?? Otherwise, 
there is no flux path and the device is ineffective.? If it is closed 
and loose on the cable, then that's good.?? If it is closed or difficult 
to close, it isn't large enough for the cable and will likely not be 
effective.?? Any gap between the halves renders it worthless for the 
application.

Just checked my KAT500 and it had V1.75 installed.? Then with the KAT500 
Utility, version 1.21.9.15, I did download the firmware from the 
Elecraft site and install V2.05 into my KAT500.?? I saw no issues.? 
Running a Windows 10 Pro 64 bit computer.

Even when properly sized, as an added insurance policy, I run a zip tie around the perimeter of the clamp-on and cinch it down tight to ensure that the two halves are in solid contact with each other. It may not be a problem, but just in case there is any play or give in the plastic snap and enclosure, this added step would address that.

Others can speak more authoritatively about this, but I thought those 
clamp-on cores, where they go right on the existing run of coax, offered 
too little inductance to be of much use below VHF.? Experts?

Pete,

Yes. You either have to have lots of them, or you need to get bigger ones and run multiple turns through them. Also get the right ?mix? for the frequency range in question. Type 31 is pretty good for HF.

Not an expert, but studied http://k9yc.com/RFI-Ham.pdf <http://k9yc.com/RFI-Ham.pdf>, http://k9yc.com/RXChokesTransformers.pdf <http://k9yc.com/RXChokesTransformers.pdf>, http://k9yc.com/GroundingAndAudio.pdf <http://k9yc.com/GroundingAndAudio.pdf> and others at http://k9yc.com/publish.htm <http://k9yc.com/publish.htm>.  There is a wealth of information there, available for free.

The impedance increases with the square of the turns.? 2 turns = 4 times 
the impedance.? It would take 4 chokes in series to equal one choke with 
2 turns.? A "turn" is one pass through the middle.? More turns is better 
until we get to very large chokes where the inter-coil capacitance 
lowers the impedance.

The KAT500 Utility software is v1.21.9.15.  Use it to download and install the KAT500 v02.05 firmware.

Have you tried under Windows?

It's always worked perfectly for me.

Subject: [Elecraft] Kat500 Firmware

Hi,
	Having difficulty loading latest version of the Kat500 utility.  The version I have is 01.75, the utility indicates that 2.05 is available.  However the new version does not load but the message ? Input hex file is corrupt, check sum is not zero?

I have the same issue attempting to load a Mac and Linux.

Perhaps 2.05 is not available?  Or is there a fix I am not aware of, or perhaps it is not necessary to upgrade?

Thank you for your interest. Help would be appreciated.

Best

That's right, sort of. But it misses the principle of how ferrite chokes 
work. It's NOT the inductance, it's the resonance formed by the parallel 
resonant circuit of series inductance and resistance coupled from the 
core with stray (parasitic) capacitance of the winding. Choking action 
is provided by the resistance associated with that parallel resonance. 
The most useful chokes are those with a broad, low Q resonance. THAT'S 
what is so special about the #31 mix, which combines the resonance of 
the winding with a dimensional resonance within the core. OTs among us 
will remember stagger-tuned IFs. Same principle.

k9yc.com/RFI-Ham.pdf  includes a tutorial discussion of this, so I won't 
repeat it here.

No. See my post in this thread about resonance.

BTW -- I strongly agree that clamp-ons should be secured with a ty-wrap. 
And something I missed the first time around, but corrected in the 
latest version of RFI-Ham is that turns must go though the core in 
sequence. Out of sequence turns cancel in-sequence turns. Learned this 
from some measurements.

Hi
As I use WinXP I had to use an older version to load 2.05? (new version of utility gave me the checksum error).

The version that loaded 2.05 correctly is 1.18.8.6

It loaded ok and works.

Rich,

If I remember correctly, there is also an updated version of the KAT500
utility, that is needed to install the new firmware version. Did you make
sure you installed that update prior to attempting the firmware update?

I am sure Don may be able to answer when the KSB2 came out with a wider 
crystal filter response, but the early on versions of the KSB2 came 
standard with a 2.1kHz filter. Today it is 2.4kHz. If you look at your 
KSB2 module and take a look at the lettered capacitors around the 
crystals and you have caps installed in the B and N positions, then it 
has a 2.1kHz filter (I think all of those caps were mostly blue in color 
as well).

Elecraft sells a capacitor kit to convert the KSB2 to a 2.4kHz or 2.6kHz 
filter by changing those lettered caps with different values to increase 
the width. It is called the SSBCAPKT and found on the site here: 
https://elecraft.com/products/ssbcapkt_ksb2-wider-bandwidth-capacitor-kit. 
As I mentioned, 2.4kHz has been the standard width sold with the KSB2 
for a number of years now.

Another thing to keep in mind is that there was also a crystal type 
change applied as well to provide a flatter response and improve audio 
quality. Again, looking at your KSB2 module, if the crystals have a "-S' 
suffix on them, then you already have the newer crystals. If not, you 
can upgrade them (and you may want to upgrade your CW crystals at the 
same time if they do not have the "-S" suffix). There is a crystal kit 
called K2KSB2XTLS that contains 14 crystals to replace both the KSB2 and 
K2 CW crystals.

It is preferred to replace the caps and crystals at the same time as it 
is easier to replace those tiny caps while the old crystals are removed 
from the KSB2 board. Replace the caps first for your desired width and 
then the crystals. It does make quite a bit of difference in audio 
response.

Jim,
When you said ?turns must go through the core in sequence?, does that mean
that each turn must rest next to the last one, rather than overlapping one
or more previous turns? I suspect that?s what ?in sequence ? means- just
want to make sure.

A very good K3 with 2nd receiver setup with roofing filters for CW operation. Std 2.7K in both rcvrs, 500 and 200 5 pole filters in main and 500 5 pole in sub. No upgraded synthesizer boards as I felt they were a bit over priced. KPA100, ATU, KXV3 Interface option for rx antennas and transverters, and hand mic. The radio was back to Elecraft in 2020 to incorporate mods including gold pins and stainless cabinet screws. Over $600 to get her up-to-date and to meet or exceed original specs. Will include invoice from Elecraft. Dust Cover also included. I believe I still have the original shipping box. I am the original owner. Asking price is $1800, shipped and insured.

Dave,

Yes. In other words, just as we would wind in sequence around a toroid. 
It limits the number of useful turns that can be wound to one side of 
the clamp. Once I realized that, I no longer recommend the clamp-on for 
TX chokes, only for RFI suppression.

Edward and Terry,

The SSBCAPKT was released November 2004.??? KSB2 kits built before that 
had a 2.1 khz filter.
Look at? your KSB2 board.? If CB and CN positions are populated, you 
have the narrow 2.1 khz filter width.

Download the instructions for the SSBCAPKT 
(https://ftp.elecraft.com/K2/Manuals%20Downloads/SSBCAPKT.pdf) and pay 
close attention to the 2nd page to see if? your BFO range will support 
the 2.6 khz width.? If not you will have to use the 2.4 kHz width.
You will want to use Spectrogram for alignment - but the link in that 
document will no longer work.? You can find a good download on my 
website www.w3fpr.com - scroll the homepage to near the bottom to find 
the links to the files resident on my website.
Position the 'knee' of the low frequency slope of the passband.
See http://www.mmccs.com/mmarc/n0ss/k2_filters_using_gram_v5r17.pdf if 
you are not familiar with setup and use of Spectrogram.

73,
Don W3FPR

On my Rev-A K2, I've changed crystals, changed the filter capacitors for 
2.6kHz, and made the drive modifications from KI6WX (I'm driving 
transverters on 10m).

People complain that the audio doesn't sound right, and the Spectrogram 
grapth is far from flat. I'm OK with RX audio but people complain about 
my TX audio.
Is there any way to make the passband flatter, or to make the audio 
"fuller"?

I am aware that TX and RX can use different filters and adjusted for 
that. I just worry about the TX reports I am getting.

If you have the K2/100, remove the KI6WX mod - without the KPA100, it 
makes no difference.
Make certain the SSB FL1 filter is set to OP1.
Check the position of the OP1 filter passband with Spectrogram? . The 
low frequency 'knee' of the passband should be close to 300 Hz.

If you are wondering what I mean about the 'knee' of the passband, look 
at the top of the passband shape and then look to the left (low 
frequency end).? Find the place where the passband response is about 3 
dB less than the flat of the passband - that point is the 'knee' that 
you need to place close to 300 Hz.

Be aware that many VHFers want to hear very wideband audio but the K2 
cannot produce that. You should have good communications quality audio - 
test on HF.

With a basic K4 how many antenna connections are there? (SO-239s) Do you get 2 RX antenna BNCs regardless of the K4 model? I'm wondering what antenna options you have between the main and sub if you don't buy the ATU?

Tnx es 73,

1.

Yes.

Main and sub always share the same antenna on a basic K4 because there's one A-to-D converter.

Thank you for your response.

Looks like I can down load 1.21.10.9, after download and Extraction I have the message Extraction completed successfully but the header still has 1.19..9.6.

I do have access to the KAT, so will leave it at that for now, too much time waisted.

Thank you again and to all those that responded

During tx, after a minute or so, the side tone level decreases until it drops out.
Great on phones. Any ideas?

Hi Gerry,

The Virtual K4 software ("VK4") is coming along. Now that we have the digital voice recorder up and running, we're turning our attention to streaming audio over ethernet, which is required for VK4.

I have been using CommCAT (by Howard, W6HN) for at least  15 years.  I have
been a beta tester.  It has one feature that really set it apart.  Every
time a DX spot  appeared that I needed for a new bend, mode, both, grid,
etc., CommCAT could send a text message or an email to my iPhone.  W6HN has
stopped supporting the program, and the text alert function is gone.

Can anyone recommend a good logger that includes some kind of alert via
text or email when a spot appears for one I need?

Thanks.  Happy New Year to all.

Excellent!? Solve the latency issue and we all hit the jackpot! 

Curious Wayne, do you have a stand alone hardware solution on the opposite end of the remoted K4 station planned? It would be great to have something like the old K3/0 but for the K4 complete w/ Paddle plug in and headphone outputs.

We can't "solve" the latency issue, we can only minimize it. Latency in 
any system is the sum of the latencies of all parts of the path. The 
parts of it under Elecraft's control are those associated with their 
hardware, signal processing, and control software, and how much 
information must be transmitted to accomplish remote operation. Most of 
the latency in most systems is the signal path outside our electronics. 
In pro sound reinforcement, it's the path of sound waves through the air 
from loudspeakers to performers and the audience. In our RC systems, 
it's the path through "the cloud."

I too am looking for different logging software. I want to control a K3S, IC9700 and IC7100 plus one other.

DXLab Suite sounds like it could work for me, but I need to know if it also has a good Net Control facility. Do you happen to know?

Hi Jim,

I've been doing remote ham radio in serious contest stations for about 10
years now...

Though is wasn't me, the guys at ZF1A achieved a 433-QSO-per hour CW rate
on remote, using a K3 and Microbit RRC boxes.  On non-ideal Internet paths,
I typically reach 175+ hour rates on CW.  This is not to brag -- it is to
illusttate that overall latency in Internet remote operation is really not
a factor in well-designed systems.  Like you say, Jim, there are many
things that contribute to overall latency.

In a previous life, i worked in broadcast TV video and audio systems, on
the Windows platform.  Audio latency was there, but mitigated by proper
techniques.


The so-called, self-proclaimed "leader" in remote amateur radiio systems
has serious problems with latency   -- so bad that I've had to resort to
using third-party, open source audio software with very low latency to
overcome issues.

As of today, the combo of the K3s + Mirobit RRC boxes rocks the remote
world.  That's not just my humble opinion, its a proven fact via results.
In fact, many bypass the audio built into other systems and use RRC boxes
to mitigate these issues.

I'm just hoping the excellent Elecraft engineering team can approach the
same level of performance in the V4 remote.

Gerry W1VE

Bob,

You said it's "great on phones."  Is that to say
you experience the sidetone volume decay
only on the internal or external speaker?

What is your headphone impedance?

The sidetone volume is controlled by
MOSFET Q5 on the Control Board.

Are you able to manually vary the
sidetone volume STL and pitch STP
using the Menu?

If you alter the sidetone level STL, does
the sidetone level remain
constant over time at the new volume
setting?

The slow decay of sidetone volume
suggests drift in the Q5 gate voltage (which
controls the MOSFET channel resistance)
or a problem downstream of Q5, including
the op amp filter which smooths the DAC
sidetone waveform.

Mike, K8CN

Works great, Fred, if you have very low latency to W7RN.  Sending winkey
over the wire and generating the CW @ the station
has always been flawless for me...  but that works for you, and that's
awesome.  There is no one solution: it's always a systems
problem.

We considered offering a faster-than-light option for the virtual-K4 software:  the EleWarp(tm). But it turned out that, thanks to supply chain issues, we can?t get dilithium crystals until 2023. Until then our CW ops will have to be content with full-impulse.

I imagine there are many who have the PR6 or PR6-10 for their K3.

Recently I had to replace the PGA-103 in mine so took the time to 
measure NF and gain at 50-MHz.

NF = 0.78 dB
Gain = 21.15 dB
Voltage at input leg=0.6v
Voltage at output leg=2.5v
80ma at 13.5vdc

That's pretty good with switching relays in-line (typ. 0.7 dBNF, 20 dB gain)

HP8970B NF meter with Maury MT7618L noise diode.

Using a new WA2ODO 2m preamp as calibration source the NF measurement 
was within 0.01 dB of that measured by WA2ODO with laboratory calibrated 
equipment.

I tried to install the new firmware this morning with the following error:

 

When the KAT500 utility connects to the port, it says unexpected device.  

 

Then I go to the main screen in the utility, and it is not reading any information from the KAT 500.  There is obviously no communication with the KAT 500 in spite of the port being confirmed open.  No installed version info and Send Firmware is grayed out.

 

I tried the force firmware mode, but my manual led does not stop blinking until I remove power.

"When the KAT500 utility connects to the port, it says unexpected device."

All the indications you have reported are consistent with the utility attempting to connect to a port that is receiving data but the data is not correctly identifying the source as a KAT500.  

What version of the utility are you using?  Have you confirmed that the KAT500 serial data cable is connected to the port you are attempting to use?

In any event this does not appear to be a KAT500 firmware issue.

I don?t know if the same exact procedure works on the K4, but this is a way to
use the digital voice recorder to compare compression levels. The procedure
is for the K3 and KX3.

Wayne, perhaps you could just offer a transverter for Subspace Radio as a
future option?

Hello Bob,

I had this happen a while back and it turned out the Q! and Q2 (transistors
that control the send and receive lines on the com port) were in operatable.
When I replaced them, then KAT500 could send and receive from the utility. I
will tell you that it is a tight fit and the transistors are SMD.


This is found on page 5 of the KAT500 schematic .

Just my experience and thoughts on what might be wrong.

Best regards and the best of the holidays,

Jerry, W1IE

I tried to install the new firmware this morning with the following error:

 

When the KAT500 utility connects to the port, it says unexpected device.  

 

Then I go to the main screen in the utility, and it is not reading any
information from the KAT 500.  There is obviously no communication with the
KAT 500 in spite of the port being confirmed open.  No installed version
info and Send Firmware is grayed out.

 

I tried the force firmware mode, but my manual led does not stop blinking
until I remove power.

"I had this happen a while back and it turned out the Q! and Q2 (transistors that control the send and receive lines on the com port) were in operatable."

I would expect that fault to result in the utility not seeing any data at all.   In that condition the utility does not report that the connected device is not a KAT500 because it can't connect at all.

Please confirm that you saw the message "Unexpected Device - Connected device does not appear to be an Elecraft KAT500" when the TX and RX data lines had both failed.  In my experience this fault can only result if the utility is connected to a port that is receiving data but it's not the data the utility was requesting.

Message-ID: <CABMvsCQ=uEVxBXLtOLaAR79zgAz90vmV67Ok2754qp=pwNg0vg@mail.gmail.com>

i have hit the wall with my knowledge of FT8.  I have my K3 configured with
a stationmaster that feeds the CAT control to/from the computer.  I can
test the CAT using the WSJT SW and it is GREEN. I can receive and decode
but TX output is not working and cannot figure out why.
The K3 goes into xmit mode when Tune is selected on the WSJT SW program.  I
can hear sidetone but there is no RF output. I can select TX enable and the
K3 goes into TX mode but again there is NO RF output nor does the bargraph
on the program indicate any TX audio.  It acts like there is no audio
getting from the computer to the rig but I have no clue why.  Audio
connections have been checked from two different computers, (MacPro amd
Optiplex 780 runnin Win 10), and both setups give the same result. Audio
cables from each computer have been verified to be good.  So I think it has
to do with the radio setup but i thinik it is correct. I am using TX Data
mode, and split shows up.  (BTW-that is what WSJT SW also says.) What am I
missing?

How is audio connected from your computer to the K3?  Are you connected
to the mic jack or the "Line In" jack?

What mode are you using USB or DATA_A (preferred)?

What are your MENU:MIC SEL and MENU:MIC+LINE  settings?

Also check your sound setting on the computer. On the sound settings window
there is an advanced tab that will allow you to select the input and output
sound devices for wsjt-x (which must be running at the time) and if you are
running win10 you may need to reset thiscafter win10 updates.

Jerry,
Years ago when I built my K2, somewhere I learned a Hakko 808 desolating tool was also an excellent enameled wire stripper and tinning device.   The 808 has been replaced by the FR-301 but I would expect similar results from this newer tool.  Either are stand-alone desoldering guns with heated hollow tip and built in vacuum.  

Here?s how to use? 
- Prop the tool upright - I wedge mine in a partially opened drawer of my work desk.
- Melt a blob of fresh solder on the hollow tip.
- Slowly insert an inch of enameled wire into the hollow tip and observe the insulation melt/burn away.
- In a second or two, activate the trigger turning on the vacuum.  Instantly the solder blob is whisked away along with the melted enamel insulation leaving a beautiful tinned wire ready for soldering into your project.

When I discovered this ?secret? all my problems and fears of preparing toroid leads vanished.  Strangely, I actually look forward to winding toroids!  I probably use the tool more for stripping enameled wire than desoldering.  This was a game changer for me.  After building the K2, I went on to construct a K1 and KX1.

And, the tool conveniently doubles as a desoldering tool!!

Steve

The tool also tins litz wire effectively, not to mention making 
non-destructive removal of components child's play. It was very 
expensive in Israel (you can only buy it through their local 
representative, who doubles the price), but I have no regrets about 
buying it.

I installed an eyebolt in a convenient place in the back of the housing 
so I can hang it up, and I just clamp the eyebolt in a vise when I want 
to use it for tinning enameled or litz wire.

Dear OMs and YL,

     Can someone please tell me what the % sign with Status message of say
67% indicates.     I think it is the efficiency of the amplifier at a given
point.    The same Status screen displays: forward power, Voltage, Current
and temperature as well as the % figure.     I looked through the manual but
can not find the answer to my question.  A quick calculation seems to
indicate it indicates power out to power input.     Thank you.

I heard that one of the major competitors is working on TSFoldDX mode.

They fold space and time so that you can just talk to the DX face to
face and hand the QSL card over in person.? Sadly, that was put on hold
due to Covid concerns.

They had it working briefly about 10 years ago, but the development of
the pocket Nuclear power pack is a bit of an issue since the Fukushima
problem.? Caused incidentally by another unexpected aspect of folding
time and space from a planet based point of view!? (But you didn't hear
that from me!...)

Seasons Greetings, Happy New Year etc, and GD DX to All.? (Though we
might be swiped by another solar event today, wrecking the ionosphere
for some, but causing some nice lights in the sky for others perhaps.)

PS:??? As I believe the K4 uses a Linux based embedded computer.? The
options for remote control are many and vast.? Some even will work with
a Windows based client.

I've not even seen a K4 let alone got hands on one, but if not already
present (I could not see reference of such in the preliminary user or
remote software control manuals) it should not be beyond possible to
have a small web server built into it's system with proper security
features (certificate based authentication and encryption) that you
could connect to with any existing web browser to gain a full and secure
virtual front panel remotely.

Or, a "K4Remote" tool, written in Java (or other cross platform
environment) that would run on Windows, Mac or other Linux machines, to
connect to your K4, and provide a full remote front panel and audio etc.

The difficulty with all of them is not the remote control, or front
panel updates, but passing audio and other time critical data (CW key
etc) with minimum latency.

Subject: [Elecraft] Simulated stereo
Message-ID: <0d8a4d25-da0b-f978-035e-1fd2d4e7cd67@gmail.com>

The K3 (and I think the KX3 and K4) has a simulated stereo function 
which allows you delay the audio to one channel slightly, which makes 
signals seem to stand out from the noise. I believe that the radios 
newer than the K3 also have the ability to create stereo separation by 
pitch, which helps in picking out CW signals in QRM.

My question is: is there some kind of device that you can get that will 
take the monaural audio from a non-Elecraft radio or a K2 and produce 
similar effects?

Dale,

This works by dividing the audio spectrum into several segments and 
sending alternate segments to different channels! It wouldn't be much 
good for CW. Interesting, though.

The spinning stripper tool works great for wire thicker than 24AWG or 
so.  But for
thin "receiver" wires it just breaks them off.

How hot does the solder need to be to burn off magnet wire insulation? I have my soldering station set to 710 degrees, and that does not seem to be enough when I try the ?blob on end of iron? method.

It depends on the wire.  I have a roll of "high temperature" 16AWG that 
laughs
at my attempts.  I generally keep my station at 750, that seems to work 
OK for
the low temperature stuff.  But even with the lo-temp stuff, you have to 
be patient.

I'd love to have one of those vacuum desoldering tools. I feel in
techno-lust with them watching Mr. Carlson's Lab on YouTube. I might try
that trick you discovered, but I found that my electronic plasma arc
lighter burns off enamel on anything but the thickest of magnet wire. Hold
the wire with pliers, though, the inductance heats the wire very fast, and
the enamel burns off in a twinkling.

I'd avoid using the plasma arc trick on a toroid already soldered to the
board at the other end. That might let out more than a little bit of magic
smoke.

If you can find one, an Orban 245 stereo synthesizer would work 
perfectly for this application.

Doug,

I use 800 deg F and a wide tip to get the job done.
Of course my Hakko 808 is a lot easier.? Clean the inside of the Hakkko 
tip after a few toroids.

The trick is to get a small blob of fresh melted solder on/in the tip of the desoldering tool.  It will stay there as you slowly insert the enameled wire through the blob and into the tip of the tool an inch or so, melting off the insulation as you go before activating the vacuum.  Practice a couple of times on scrap wire to get the non-critical timing right and build your confidence.  

I?ve only tried fine (22 - 30) gauge or so wire typical of QRP or receiver designs.  For a high-current heavy gauge wire used in power applications, I suspect some combination of the usual sanding, burning, and scraping would be appropriate.

It really is brilliant!  I wish I could remember who I got the idea from years ago, but I thought it such a good ?secret? that I promised (mentally) to pass it along periodically - particularly when the subject comes up.  Like most, until that point I struggled sanding, burning, scraping? to get enameled wire clean enough for soldering, never confident the job was well done.  No longer with this method.

Merry Christmas,
Steve

Logger32 does this very nicely.?? Have used this for years.? Can ring an 
audio alert on the PC speaker when it sees one you need and have set 
filters for.?? I suspect N1MM might do this also via the telnet window 
but have not tried that part exactly.?? T
he logger needs to access a online cluster like the VE7CC Telnet via 
internet so it takes a bit of integration config to get it all working 
but it is stable and faultless for me over many years now.

Hi Gwen,

I love my Hakko FR301 de-soldering gun but, while I've used a variety of melt/burn techniques for enamel wire insulation, I had not thought of using the de-soldering tool.  I haven't noticed anyone mention wire stripping tweezers, which I've found to be a really handy tool when making inductors with a variety of wire sizes. I settled on a single size tweezer:

https://au.element14.com/knipex/15-11-120/wire-stripper-0-6mm/dp/875958?gclid=EAIaIQobChMI6Ongl-b99AIVwg5yCh3cgwwJEAQYASABEgLFsPD_BwE&mckv=_dc|pcrid|501152839127|pkw||pmt||slid||product|875958|pgrid|123988903131|ptaid|pla-293946777986|&CMP=KNC-GAU-GEN-SMART-SHOPPING

Purists would probably have a few different sizes but the one referenced deals with my requirements for small receiving toroids, up to (e.g.) the LPF inductors in the 2200 m PA I've just finished (about 16 AWG, as I recall).  These tweezers are very sharp and quite compact, so they can be angled to optimize the tinned lengths on e.g. partially-mounted toroids.  It's a slightly longer and calmer process than the melt/burn approach.

73, Peter (VK6HP).

Subject: [Elecraft] KX1 RX and TX Problem
Message-ID: <96B97C79-23B7-4DFE-A364-ECD407A5688C@icloud.com>

I had the pleasure of recently assembling a KX1 and KXAT1 kit. I had the KX1 working on both 20m and 40m, which last worked on Sunday. Unfortunately I now have the misfortune of debugging an issue with it.

Today I found the RX and TX no longer work. The KX1 powers on, the menus behave as I expect, the AF gain changes the audio and Filter knob changes the audio, tuning results in the ATU relays clicking but without any power out the tuner doesn?t find a solution and displays 0 W and 9.9 SWR. The RF Gain knob doesn?t have any noticeable affect. 

I?ve done the following:
* Inspected the KX1 for poor solder joints and shorts, found none
* Verified R4 is fully clockwise
* Verified Q6 collector is isolated from ground
* Removed the KXAT1 and jumped J7 pin 1 to pin 3
* Verified TX is 0 W with an external wattmeter
* Completed the voltage tables

The voltage tables indicated the following issues:
* U1 pin 14, expected 0V measured 5V
* Most U2 pins do not measure expected. I attribute this to U7 2.7V power output measuring 1V.
* U7 pin 4, expected 1.17V measured 0V
* U7 pin 5, expected 2.69V measured 1.0V
* Q5 Emitter on Tune expected 2.24V measured 1.48V
* All other measurements were in family with the expected values

The issue that sticks out to me the most is the U7 pin 5 output is too low. This results in the DDS U2 not receiving the power it needs to operate, hence most of the U2 voltage measurements do not match predicts. Is there any reason this 2.7V output could be low besides U7 failure? Are there other areas I should probe not included in the voltage table? The U7 input voltage is good, 5V. Do I need to replace U7?

To make matters worse, while I was measuring the Q6 collector voltage, I briefly shorted the base to the collector with the DMM probe. I have not noticed any new issues with the KX1. The KX1 still turns on, the buttons work, etc. Are there parts I should check to make sure I didn?t break or stress anything? 

Thanks and Happy Holidays everyone!

Some of the various Heil headphones, including the one on the Elecraft site, have a switch that passively selects between mono and simulated stereo by changing the phase between the two sides. It basically seems to widen the perceived space of the sound source, possibly helpful.

Any *Stereo* headphones can accomplish the same thing by simply adding
a DPDT switch wired to reverse the connections (invert polarity) to
one of the two ears.

Merry Christmas,

 ?? Snow has been falling for the last few days; sometimes heavily.? It 
is no longer melting each day.? The trees look like folded beach 
umbrellas.? Very few of them have shed any of their load.? I expect that 
to happen overnight so it could get loud :)

 ? The sun has been active all week.? The noise level could be higher 
due to some flare activity.? But with stronger signals the noise is 
easier to control.? The snow fall has limited me to one antenna.? 
Hopefully, it will be good enough to collect quite a few of you.

I second these tweezers. They're great.

While Elecraft supplies heat strippable wire, everything else I have
isn't and the tweezers make easy work of it.

These tweezers are very sharp and quite compact, so they can be angled to optimize the tinned lengths on e.g. partially-mounted toroids.  It's a slightly longer and calmer process than the melt/burn approach.

I'll try that. I was also thinking some kind of reverb device could be 
used to insert a variable delay on one side.

So how about a stereo effect where the position of the signal depends on 
its frequency?
Low frequencies on the left, high to the right.  A linear progression 
across
your head?

I thought this was one of the stereo effects the KX3 did already.

Yes, that would be great. The K3 doesn't do that, unfortunately.
The K2 and my other non-Elecraft rigs don't have the 'presence' that the 
K3 gets from the ability to insert a slight delay on one side.

I had a KAT500 fail to xmit back to the PC, but it could receive, so  
only one of the transistors was out.

To determine this, use Putty or other terminal program to send test  
commands to the serial port that shows up when you plug in the USB  
cable.  If you can command the KAT500 to switch antennas, for example,  
but you see no return message when you ask for the firmware version,  
then you will only need to replace the transistor that drives the  
KAT500 to PC line.

Good Evening,

 ?? Conditions were so-so to OK.? Rapid QSB was on everyone, it chopped 
up weaker stations, the stronger ones were better.? More than one 
operator mentioned I was the only station on the band.? I did not hear 
anything except check ins on either band.? I don't think it was due to 
lack of focus.? However, an hour with a chainsaw followed by working 
with cold hands did affect my sending.? It took a word or too for my 
fingers to lubricate.

 ?? During the second check in on the second net I watched a large tree 
bend over and then fall over.? It rotated around its root ball like it 
was a ball socket.? It fell in one of my antenna paths.? If the antenna 
had not already been broken it would have fallen today.? I was also 
taking each second as it came because the power kept blinking.? If there 
is any wind tonight there will be a power outage.? For some reason this 
layer of snow is not sloughing off of the trees.? Power lines don't like 
it either.

The K3 does have several stereo functions, including something called 
"binaural" and a few delay settings. But it does NOT have the capability 
of spreading signals out by frequency like the KX3 can.

Message-ID: <c541a97d-1183-ded1-119b-5b14c257dc77@gmail.com>

Greetings,

 ? Has anyone using Win4K3 Suite with a KX3 and KXPA100 been able to get 
the KXPA100 to show up in the Controller menu ?? Is another KXUSB cable 
required?? How is your system all connected?? Is this even necessary or 
even possible ?? I have my KXPA100 and KX3 connected as diagrammed in 
the manual(s) and I see no way to create another KXUSB connection at 
all.? If you have this config working, I'd appreciate some direction.

 ? Looking for guidance - thanks in advance,
 ? John - N0HJ

John,

Only one KXUSB is needed.? The other is just a TRS to TRS cable.
The KXUSB cable must connect first between the KXPA100 and the PC.? The 
second cable between the KXPA100 and the KX3.
If connected that way, everything should work.
See if both the KXPA100 Utility and the KX3 Utility will connect properly.
I don't know what Win4K3 suite does in its routing.

73,
Don W3FPR

Matt,

You likely have a problem with U7.? At least, that is the thing that you 
need to resolve first.

Sorry about U6, it usually makes a loud pop when the base and collector 
are shorted.? You will have to replace it before you get any power out.

Don W3FPR

The KX1 powers on, the menus behave as I expect, the AF gain changes the audio and Filter knob changes the audio, tuning results in the ATU relays clicking but without any power out the tuner doesn?t find a solution and displays 0 W and 9.9 SWR.

I didn't have a good night in the K1USN Slow Speed Test. I started
more-or-less on time and tried to answer CQs. None of the 
stations I tried
could hear me. My SPE 1.3K amp said I was putting out about a kilowatt,
although the antenna tuning on my normally low SWR 40M dipole 
needed to be
redone. I was receiving many stations, at normal levels.

After a few minutes, I started searching for causes, since 
operators calling CQ weren't hearing me and sending CQ again. 
Some of these operators had worked other stations, so I knew 
their radios were basically working. I tried maybe a half a 
dozen stations.

Finally, in desperation, I raised the tune power in my K3 
exciter to 15W
and retuned the dipole yet again. Things started working and I 
managed to
check into the Elecraft 40M CW net via KD5ONS in OR at 0050z. 
With only 5
minutes in the contest left, I managed QSOs with W6SX and VE5MX. 
Thanks to
both of them.

My current theory about what was happening is that ice on the 
antenna was
eating transmit power, although receive seemed normal. Does ice 
seem a
reasonable explanation? What else could be the cause? I'd love 
to come up
with a believable answer. Even more so, avoid the situation in 
the future.

Hi Don,

 ? Thanks for the recommendations and comments.? Both the KXPA utility 
and the KX3 utility communicate fine with my hardware setup.? I'm 
guessing the WIn4K3 Suite does not properly communicate with both 
devices through one com port.? I'll see if I can post on their groups.io 
forum and see what they may have to say.

Thanks es 73 - john - n0hj

I doubt that pogonip or even solid ice on your antenna would have major 
effects [well, except for weight].? Ice forming from water directly from 
the sky is a pretty good insulator.? We had a very large Log-Periodic on 
the roof of the hangar at my first USAF assignment in the remote 
northern interior of KL7.? Lots of ice fog creating rime ice on the 
elements in the dead of winter, much of which was -35 C or below.? In 
the so-called spring, solid ice would form on them, and there was 
essentially no perceptible change in the antenna performance.? If your 
ATU wasn't getting enough power to tune, it was probably "eating your 
power" rather than the ice on the antenna.

At home, I have an HOA "WOOF" antenna [Wire On Organic Fence] at about 2 
m AGL.? We've been having a series of snowstorms, the top of the fence, 
including the wire, was encased in snow yesterday for the 40 m ECN, and 
it worked as good as it ever does.

Yuck!? As a retired recording studio engineer, CBS Records, having the 
same signal out of phase by 180 degrees to one ear, is much like 
sticking and ice pick in ones ears.

Most systems will have a variable phase shift depending on frequency, 
usually not to exceed 30 degrees.?? In this case, the leading phase 
signal will appear from that direction.?? In others, bandpass filtering 
moves the higher frequency to one side and the lower to the other.? From 
an audio perspective, this still sounds like "fake stereo".??? It is 
just messed up monaural.? There's lots of that today.

The K3S has the AFX function that does an excellent job of signal 
spatialization and sounds quite nice on SSB signals.

I doubt that ice on the antenna would have any effect in terms of 
increased loss.?? However, I would expect the resonant frequency to 
change and thus the need to adjust the tuner.?? If it is and ATU / 
automated tuner, then perhaps a bit too low power may cause the SWR 
bridge to read incorrectly.

I use a KAT500 and my TUNE power is 20 watts.? This assures the ATU and 
SWR circuits have adequate signal to perform the desired function.?? As 
to the SPE 1.3K amp, as fussy as they are, I'm surprised it didn't trip 
off line.

My experience with antenna's changing due to moisture is with my 
balanced center fed wire which uses window line for the feed.? It 
accumulates moisture, frost, rain, snow, and ice.? The change I do see 
is due to the velocity change of the balanced feed.? My measurements of 
a couple of years back indicated the length of the line changed 
electrically thus a velocity factor change.? Any loss, wet or dry, under 
matched conditions was not measurable over a length of 100 ft on 20M.?? 
Therefore, I would expect the mis-matched loss to be about as the book 
say.? Again, either wet or dry.

Message-ID: <d945cf51-2260-791e-c860-3a191e986141@acsalaska.net>

Operation of the the KXPA100 with its tuner works great with my KX3 
using the KXUSB cable (particularly nice when KX3 is mounted on my truck 
dash and amp is under the back seat.

But I also use the amp/tuner with my K3/10 (low power version) which has 
no KXUSB jack.  I just connect PTT to the amp.  Works great and tuner 
tunes well.  But when I change bands the amp/tuner seems confused. 
Doesn't change antenna connections or tuner settings when I transmit 
using the XMIT/TUNE button on the K3.

I've found thru trial-n-error that cycling the amp power off/on seems to 
then do the changes needed and it tunes well (remembers pre-tuned freqs.)

I'm guessing the KXAT100 detects frequency change but does not activate 
the tuner settings until I reset it with the power cycling.

Just curious if this is normal behavior?

My setup:
ANT1: connects to 6m antenna (BYP) or triband HF yagi (MAN)
ANT2: connects to 80m dipole (BYP)
K3-->KXPA100 ANT1-->ant switch-->6m yagi or HF tribander
              ANT2-->80m dipole

If switching from 6m to tribander I switch the ant switch before 
transmitting.  Usually I manually change ANT1 to ANT2 by Press/hold TUNE 
on the amp if switching to 80m.

"This is the best rig I've ever used"

That's a bit vague.? Which other rigs are you comparing it to, and what 
specifically makes the K4 so much better?? I assume you like the 
ergonomics, but have you also found any performance advantages, and if 
so what are they?

Thanks and 73,
Dave?? AB7E

Message-ID: <21768530-C107-428E-9672-FA6D802D94EB@me.com>

Santa Claus brought me a cheap 14 volt wall wart style power supply. The purpose of this is to charge the K2 built-in battery.
 
https://smile.amazon.com/PERFEIDY-Switching-Regulated-Transformer-Interchangeable/dp/B09DSCD62C/ref=sr_1_8?keywords=14+volt+wall+wart&qid=1638756395&sr=8-8 <https://smile.amazon.com/PERFEIDY-Switching-Regulated-Transformer-Interchangeable/dp/B09DSCD62C/ref=sr_1_8?keywords=14+volt+wall+wart&qid=1638756395&sr=8-8> 

The unit is made in China, and the cost is $16. The nameplate rating is:
Input: 100 - 240 V AC 50/60 Hz 1A
Output: 14.0 V DC  1.0 A 14.0 W

The unit comes with a selection of connector adapters of various sizes, but the connector that is wired onto it is the right size for the K2 power socket.

Recall that the K2 receive current requirement is in the neighborhood of 120 - 250 mA, while the transmit current is 2.0 A or more, or potentially somewhat less if current limit is set. So this power supply is adequate for charging the battery, adequate for receiving, and inadequate for transmitting. 

After the battery has been fully charged (overnight) with the 14.0 volt power supply, the radio shows 13.8 V when the PS is connected, and 12.9 V with the PS is disconnected.

With the battery discharged so that it shows 10.0 volts with the PS disconnected, then when the PS is connected it shows 13.7 volts. This suggests that the PS is barely able to maintain its rated voltage output under a heavy charging load.

With the 14.0 V PS connected, I am not noticing any new noise when receiving with an antenna mounted outside my house. I have not tried transmitting.

A concern might be if the battery is fully charged using the 14 volt supply, and then a conventional 13.8 volt supply is accidentally connected with the battery turned on in the radio, then the voltage regulator of the conventional power supply might get confused.

This power supply seems to solve two problems:

1.) Cheap, small portable power for battery charging when traveling.
2.) Higher voltage than conventional ham power supplies, which should help battery life.

All,

   Ebay is crawling with Netgear wall warts that are rated 12V 3.5A.
They are ideal for a K2.  The connector fits, too.  I got a couple of
them at the ham swap a few years ago.  Sold to me by Mark, the CTO
of Netgear.  He would show up at every flea market in his ancient
VW bus, selling detritus from the Netgear labs.

I was under the impression that we set the K2 for 3.5Amps under the initialization, so maybe a 4amp supply like the one made by Pro Audio Engineering??

The ice should not have a significant effect on your signal strength. With a
KW, everyone should hear you fine unless there is a water/ice issue with
your center insulator. Ice is a poor dielectric, it will make your dipole
wire electrically longer so a tuner will likely be needed to make your
radio/amp happy. Good coax will reduce your feedline SWR losses.

Bob -

Should you ever feel the need to replace your feedline, open wire line will solve that problem.

I doubt that ice on the antenna would have any effect in terms of 
increased loss.   However, I would expect the resonant frequency to 
change and thus the need to adjust the tuner.   If it is and ATU / 
automated tuner, then perhaps a bit too low power may cause the SWR 
bridge to read incorrectly.

I use a KAT500 and my TUNE power is 20 watts.  This assures the ATU and 
SWR circuits have adequate signal to perform the desired function.   As 
to the SPE 1.3K amp, as fussy as they are, I'm surprised it didn't trip 
off line.

My experience with antenna's changing due to moisture is with my 
balanced center fed wire which uses window line for the feed.  It 
accumulates moisture, frost, rain, snow, and ice.  The change I do see 
is due to the velocity change of the balanced feed.  My measurements of 
a couple of years back indicated the length of the line changed 
electrically thus a velocity factor change.  Any loss, wet or dry, under 
matched conditions was not measurable over a length of 100 ft on 20M.   
Therefore, I would expect the mis-matched loss to be about as the book 
say.  Again, either wet or dry.

Subject: [Elecraft] KX1 RX and TX Problem
Message-ID: <AC69197A-1AF9-4FBB-B703-70DECF39BA01@icloud.com>

??Thank you Don,

I ordered a TPS76427 and a couple spares from Digi-Key and will replace U7. 

Any thoughts on what may have caused U7 to fail? ESD comes to mind, though I used an ESD mat and wrist strap anytime I worked on the KX1. Part infant mortality also comes to mind. My primary concern is the U7 failure is a symptom of some other failure I have yet to discover. My worst fear is I put a new U7 in and it fails the same way. Have you seen U7 fail in other KX1s?

I ordered a replacement 2SC2166 MOSFET for Q6 from RFParts. I?ll replace it once I repair the U7 issue.

73!

Yes, I agree that true open wire line does not have that issue. However, 
in as much as I have the feed-line from the antenna, standing off of the 
tower some 18", entering through an eve vent, then through the attic 
supported under the wood roof rafters, and dropping down through the 
ceiling to my operating position, using true open wire line would be a 
challenge.? In my installation, I add 10 twists per 10 ft so as to 
minimize any adjacent item causing unbalance plus minimize any wind 
loading.? With true open wire line, this would be a challenge.

I've used this system for more than 25 years with a great deal of 
success and very little to zero issues.? It is just ones understanding 
the need for a slight adjustment of the ATU values to compensate for 
weather changes.? No different than frequency changes.? The KPA500 or 
the KAT in the radio handles any needed changes 100%.? The currents in 
each side of the line are balanced to 5% or better and there is no 
measurable common mode current.

I wish more hams understood this and they would likely have better 
antenna systems, as opposed to some of the haywire crap I've see at some 
QTH locations.

Thanks

Bob -

I don't have the tower issue, but my OWL comes into the house thru soffit vent spaces (the metal vent has been replaced by a plywood panel), runs over ceiling joists (wood) to the balun and short coax to the KAT500.  I bought a 300 foot piece, and used about half.

Lyn:

Can you comment on the balun you are using between OWL and the KAT500 -
Specs, etc?

Only needs to done once per band unless the noise source really 
changes.?? Of course the contest guys are changing bands every 3 
milliseconds, so that might be a chore.

That should not be the case unless your K2 circuit is modified. D10 on 
the RF board prevents voltage from the battery to reach the DC power 
connector on the back. So there is no voltage from the battery to the 
power connector and the power supply does not get confused.

It is the same D10 that makes power supply selection for charging 
difficult, BTW. In order to get 13.8V on the battery for charging, one 
must pass D10 *and* the resistor in the KBT2 kit. Note that D10 got 
changed to a schottky diode as part of the K2 A-to-B kit. Still, I have 
my K2 power supply set to 14.2V for this reason.

Note that "hey, I found a power supply that doesn't generate noise" for 
me is just one selection criteria for power supplies. Other 
considerations are safety and protection: correct fusing and the like. I 
had a cheap charger explode within 8ft distance in a shack a few years 
ago. The explosion ripped the casing out of the wall socket, ripped the 
casing apart and left the electronics smoldering on the hotel carpet. 
The thing sounded like a pistol shot but didn't even trigger the mains fuse.

My question, then: would you mind if something like this were to happen, 
in your shack, at night, and the resulting situation starting a fire? 
There is a reason that "brandname" power supplies have more protection 
circuitry: if there would be a fire in your shack, then with a brandname 
power supply this is a liability case.
With an Amazon Special, whom would you make responsible?

That is why I either use brandname power supplies or only charge when I 
can attend the charge process. I don't want to badmouth your purchasing 
decision, but perhaps this gives something to ponder.

Hi Bob,

>> Yuck!

Indeed that's what I would say also.
I for one can't stand anti-phased headphones. I once discussed that over 
using stereo-headphones being fed at tip and ring and left the common 
open. The comment was: No one hears that. Well I do! Splitting mono into 
high and low pitched sound seems fine at start but fatigues just as much 
as anti-phase. Only the spacial setting on the KX3 is very useful but 
even then I like to switch back to mono at times.

Just my ?0,01

My awe and excitement hierarchy report varies with age and experience, the
older I get, the more muted my global response. My new K4 gets a 10/10. K3
gets an 8. Icom 775  gets a 9 initially in 1996 but downgraded to a 7 when
K3 replaced it in 2008. Most exciting was Signal One CX7A in 1971.
Breakthru technology then. RF clipping and 1.5 shape factor. Youthful
excitement was overflowing. Other rigs nIce but not special. K4 will
possibly be my last supreme rig, especially when pure signal arrives. K4 is
beautiful to behold and use. My spec chasing days are over. Now it it is
simple experience and dazzle. Bravo Elecraft!!

Can you explain which performance differences differentiate the K4 from 
the K3 to make you rate one a 10 and the other an 8?

Thanks es 73,

did you check at the Elecraft page directly
(https://elecraft.com/pages/manuals-downloads)?

There is a dropdown for "K4 Manuals" -> "K4 High Performance Direct
Sampling SDR Manuals and Other Materials" and the 4th entry should be
the manual you're looking for as PDF.

Hope that helps es vy 73 de Thorsten, DH4FT

I think the only thing that is for sure is that this is very poorly documented.? 
The schematic shows two resistors, the assembly manual shows one, and the 
correct value of the one (by my measurement) is unknown.? Whether or not it is, 
or isn't, used is another unknown.? It seems to me that Elecraft could comment 
on this and clear this up, but that hasn't been forthcoming.? Silence isn't 
always golden.

I think so. The mysterious R7 may have been left off of the final circuit board precisely to cause such a bad mismatch that it would be obvious to operator, software, or both, and so that corrective action could be taken.

Hi Joachim , How are you adjusting the power in each of the three power settings.  Do you have the coax and dummy load connected directly to the K3?  Trade out the short jumper to the dummy load to assure yourself it is good.  After that, I would measure power with an external calibrated wattmeter.  The K3 utility is obviously not seeing the power it is looking for, low by .5 to 12 watts depending on the power setting.

I am looking for a source (besides Elecraft) of the E620021 connector and pins that is used in the K1. It is the 2 pin female connector that plugs into the speaker connector on the RF board.

Does anyone have a source (Digikey, Mouser, Allied, Newark, etc.) and the correct part numbers for both the connector housing and the connector pins? I'd like to have a spare connector and several pins in the event I break a wire or want to add a Cumbria Designs X-lock board to my K1.

Message-ID: <a5bc3fd4-bf3d-a9f0-9678-6deac848f365@bell.net>

After putting up a new antenna for the WARC bands, I noticed that the 
signals on the 12M band
on the KX3 seemed kind of muted and decided to check the sensitivity 
with the signal generator.

Pre-amp on the KX3 was set to 20 dB for S9 with a signal of -73 dBm on 
all bands. All bands seem
to be OK except 12M where a signal of -63 dBm was needed to get S9 on 
the S-meter.

Any ideas or suggestions? Thanks!

Iforgot about the attenuator and that it's set per band!? Time to get

Subject: [Elecraft] Cleaning Solder Flux, Redux
Message-ID: <000f01d7fe88$5d4c0730$17e41590$@aya.yale.edu>

 

Is there a consensus among builders of the traditional kits (K1, K2, etc)
about the best way to remove solder flux from a completed circuit board?
Some Internet sites recommend acetone, others say isopropyl alcohol. A few
tout their own product without saying exactly what it is.  I remember
reading someplace that one or the other of those will clean the flux but
could also cause damage by being absorbed into components.  Yes, I know this
is all purely cosmetic but if it can be done safely I'd like to try it on
the next kit.  Suggestions?

 

Thanks,

 

Ted, KN1CBR

Professionals use 91% Isopropanol.  You can get it at CVS cheap.

Is there a consensus among builders of the traditional kits (K1, K2, etc)
about the best way to remove solder flux from a completed circuit board?
Some Internet sites recommend acetone, others say isopropyl alcohol. A few
tout their own product without saying exactly what it is.  I remember
reading someplace that one or the other of those will clean the flux but
could also cause damage by being absorbed into components.  Yes, I know this
is all purely cosmetic but if it can be done safely I'd like to try it on
the next kit.  Suggestions?

 

Thanks,

Happy New Year,

I think N7WS has shown that when that window transmission line gets wet, its loss goes way up. So some of the change you are seeing in rain/snow conditions could be due to this higher loss.

Yes. Excellent lab-quality experimental work done many years ago. It's 
in one of the ARRL Compendiums of technical papers. He set up runs, got 
them wet, and measured loss.

I supervised a Metrology lab at a commercial nuclear power plant for 34 years. We also performed component level repair to ?safety related? equipment. We used isopropanol applied with a stiff ?acid? brush (cut the bristles short). Never had a problem with NRC audits. 
That being said, if you ever work on a board that is humidity sealed (plastic type coating on solder side), be very careful as the alcohol will loosen the coating and it will do a number on unsealed potentiometers and switches!

I am aging out of making a radio work by making many settings on the K3.

I am considering to buy a Genovation Keypad for CW, RTTY, FT8 mode 
settings and others such a band? and other settings on the K3.

I need a mentor who is willing to guide me.

In return,I will sponsor you as a member of the BIG Radio Club, upstairs. :)

Depends on what flux was used. The current crop of "no clean" fluxes does
not come off well with isopropyl alcohol and leaves a white film on the
board. Other fluxes dont have this problem.

I use the same stuff we use at work for light rework which is the heavy
duty flux remover from MG Chemical.

 Acetone will eat some types of plastic and should be avoided.

After reading all the comments on this thread, I think that 
Skip, K6DWG and Bob, K4TAX have the best theory of what 
happened. Careful reading of the SPE 1.3K manual indicates that 
the power output of the amp is sampled between the amp and the 
internal tuner and that the recommended tune power is 30W.

So the idea that the tuner could have gotten into a state where 
it ate the output power is at least credible. I would expect a 
KW dissipated in the tuner to have damaged it, but fortunately 
that does not seem to have happened.

The manual strongly recommends setting the exciter radio (my K3) 
to maximum power output and trusting the ALC to set the correct 
drive power. Many here, including me, will disagree. However, as 
a result of this recommendation, the manuel doesn't really 
address the drive power issue.

Please note that the antenna is driven through coax and not open 
wire or ladder line, so theories based on those feed lines don't apply.

Thanks to everyone who replied. This list is a wonderful resource.
