Re: [Elecraft] K3 Receiver frequency adjustment

[Fred Jensen]

All good advice BUT ... before you do anything, look up Wayne's RefCal 
procedure on the Elecraft site. I think Don, W3FPR, may also have it.  
It's not hard, you just have to go slowly and be very meticulous at each 
step.  I have my K3 #642 within 1 Hz of WWV, and it stays there.  It's a 
fun adjustment too because there are very few things we can adjust to 
within 1 part per 10 million and no test equipment. [:=)

Why don't you check an actual known frequency???  Relying on packet

If the USB cable is disconnected from the K3S, the USB Sound Card (USB
Audio CODEC) will no longer be available.

You have to switch WJST-X to use the sound card in your PC.  And you
have to run two cables:

K3S LINE OUT to PC LINE IN (or MIC)
K3S LINE IN to PC LINE OUT (or SPKR/Headphones)

Adjust levels using the Windows level controls and CONFIG:LIN OUT and the
MIC GAIN knob (which adjust LINE IN level when MAIN:MIC SEL is set to LINE).

Re: [Elecraft] K3 Audio from RS232 connection?

[Bill Frantz]

You can use the line in/out connectors in the back of the radio 
and a "sound card" for your computer. USB sound cards are 
available inexpensively from Amazon. I have one for my KX3 which 
I think cost about $5.00. You may need to install a pad to lower 
the signal level between the line out on the radio and the Mic 
in on the sound card.


In an ideal world, you will get the the RJ-45 connector 
repaired, either locally with someone who can re-solder the 
surface mount connector or by getting it repaired by Elecraft.

Re: [Elecraft] K3: KIO3 dgital board failed (I think)

[David Gilbert]

I had exactly that same problem, Ed, and I also first thought it was the 
USB/RS232 cable (which it wasn't).  I also do not need the direct USB 
connectivity, or the associated internal sound card. Luckily, I was able 
to buy replacement boards from someone who had done the upgrade to the 
KIO3B for another ham and still had the old boards, one of which ... the 
audio board ... was itself bad but at least the RS232 board was good.  
Problem fixed.


In my case, the KIO3A apparently was damaged by a line transient that 
came in via the laptop that was connected to the USB/RS232 line.  Most 
everything was disconnected at the time, but that line wasn't.


I had sent an email to Elecraft technical support when I first had the 
problem, asking whether or not they had replacement boards or whether 
they could fix the KIO3A.  The tech didn't bother to answer either of 
those questions and simply replied with a rather curt "just upgrade to 
the KIO3B ... you'll be happier".


Somebody could probably make a small business gathering various older 
K3/K3s boards from folks who had done various upgrades in order to 
service users like us who can't get help anymore from Elecraft.

Re: [Elecraft] [K3] KAT3 not functioning on 6m

[Bill Coleman]

No, that’s not it. The right is ALREADY in split mode when i attempt to use the 
auto-tune. 

You get the N/A flash if VFO A and B aren’t set to the same mode, other than 
SSB/CW. 

WSJT-X sets it up correctly, with both VFOs in DATA mode.

Re: [Elecraft] [K3] KAT3 not functioning on 6m

[Richard Ferch]

The K3 allows split in data modes, but only provided both VFOs are already
in data mode. The K3 will not allow cross-mode split between Data and
CW/SSB.

If you are seeing "SPL N/A" when you try to enable split with VFO A in a
Data mode, what that tells me is that VFO B is in CW or SSB, not in Data
mode. When VFO B is not already in the same mode as VFO A, tap A>B twice to
transfer the VFO A mode into VFO B before pressing Split.

Re: [Elecraft] [K3] KAT3 not functioning on 6m

[Bill Coleman]

This is a feature of WSJT-X. If you have the Split Operation selection set to 
“Rig”, WSJT-X will always use Split mode.

It sets the transmit frequency higher or lower in 500 Hz increments. The main 
reason for this is to keep the generated audio in the middle of the SSB 
passband, but high enough to allow harmonics to be outside the passband.

So, for example, if you select 400 Hz as your transmit frequency, WSJT-X will 
set the TX frequency 1.5 kHz lower, and then generate transmission tones around 
1900 Hz. If you set the frequency to 2000 Hz, it will set the TX frequency 500 
Hz higher, but the tone generated is about 1500 Hz.

The net result is the same — the transmitted tones are always between 1500-1999 
Hz.

And even if you select a transmit frequency between 1500-1999 Hz, WSJT-X will

Re: [Elecraft] [K3] KAT3 not functioning on 6m

[exbpi]

Bill,

Why are you running split in WSJT? The only time you actually need split is 
when operating 2 different frequencies like working JA's on 160 when they used 
to be required to transmit on 1908 KHz and we transmitted on 1840 kHZ (they now 
can operate on 1840). Unless you are actually needing to receive on one 
frequency and transmit on another, set the radio configuration to "Fake It" 
instead of "split". That will keep your transmit frequency in the middle of 
your transmit bandpass. There is no actual frequency change in WSJT including 
DX expedition mode.

OK, I figured this out, sort of.

Every time I’ve had trouble with the KAT3 not tuning, the K3 has been in split 
mode.

By taking the K3 out of split mode, I’m able to turn on 6m correctly.

Oddly, though, when I return to split mode, it still works. 

I’m not sure why I see this issue, but I’m glad I can work around it.

Split mode is often configured due to the WSJT-X settings, depending on the 
frequencies used.

Re: [Elecraft] [K3] KAT3 not functioning on 6m

[w4sc]

Bill,

I had an issue very similar.  The “Automatic TXGain” procedure is performed at 
52 MHz.  I was using a 50 ohm load attached, and at 50.125 the KAT3 have 
trouble matching the load.  Also it appears there is not enough power out in 
the lower part of the band for the SWR bridge to function. 

Part of the problem is I believe, the f/w switches the KPA3 ON at 8  watts 
instead of the usual 12………..

Performing a MANUAL TX Gain procedure on 6M may help. 

Here is link to post I made several weeks ago.

Re: [Elecraft] [K3] KAT3 not functioning on 6m

Update on this - this problem with the KAT3 ATU not working on 6m appears to be 
intermittent. Sometimes it will tune, sometimes it won’t. Weird.

Re: [Elecraft] [K3] Issue with HI CUR on 12m

I checked this. Voltage was 13.8 volts no load, dropped about a volt under load.

I cranked it up to 14.4 volts no load, and it’s better, but still getting HI

Re: [Elecraft] K3 vs Icom UI (was: KPA-1500 SWR fault above 700-800 watts on 160m)

[Josh Fiden]

I have a 9700 and since it looks nearly identical to 7300 assume the UI is 
similar. Intuitive? Not at all. K3 has lots of buried items but they are easy 
to find and mostly set once & forget. Only gripe would be all the 
abbreviations, but that was obviously limited by a practical display choice for 
it’s vintage. 

Improved UI with the big display is near the top of items that interest me 
about K4.

Re: [Elecraft] K3 Transmit Timeout for Remote Operation

[Dana Roode K6NR]

I didn't get any response to my query below, but I have a solution in place
finally.  I'm no electronics wiz but I found some circuits and constructed
something based on a 555 that works nicely.  If any else is interested in
this, let me know.Dana

Re: [Elecraft] K3 on 2 meters

[Charlie T]

I never bought any extra stuff for my internal 2M transverter and I've used it 
on quite a few VHF contests etc.
So, as far as I'm concerned, the REFLOCK option is definitely NOT required for 
normal 2M CW/SSB contacts.
The regular calibration routine gets me close enough for anything I'd be doing.

Ronnie, it's a REFLOCK board that is installed INSIDE the 2M module It is 
"highly recommended" (was), so that IMPLIES that the 2M module can be used 
without it, but at some sort of reduced accuracy in frequency I would guess.

My 2M module install turned into the need to ship it in and fix several issues,

Re: [Elecraft] K3 going expeditionary

[K8TE]

As is often the case, connecting directly to the battery for the negative
lead is misunderstood.  In today's world, it depends.  The Battery
Monitoring System (BMS) is a big deal in most of today's vehicles.  To
function properly, we should NOT CONNECT to the battery's negative terminal. 
That used to be good advice and may be bad today.  See:  
http://www.k0bg.com/wiring.html.

As Alan, K0BG, states, "It WORKs." often means "WithOut Real Knowledge.  Not
all advice on this reflector is current or correct.  Caveat emptor.

BTW, using vehicle wiring for a 100 Watt radio can lead to losing the
vehicle due to fire!  I have seen the pictures.

I worked in the Gulf of Mexico oil fields.  I swatted down with gusto the
idea of "It's only temporary." and "I can do it quickly."  Do it right, even
if it's for an hour or a weekend.

73, Bill, K8TE

Re: [Elecraft] K3 on 2 meters

[w4sc]

The   K144RFLK  is showing as available on this page.  However, clicking the 
item takes you to a page suggesting to “signup” on an interest list. 

https://elecraft.com/pages/k-line-transceiver-k3-k3s

Also, to use an external 10MHz reference,  K3EXREF is required.

My K3S is currently in Watsonville for “final upgrading”, and two items to be 
installed are the K144XV and K144RFLK.

If your K3 has been upgraded to KSYN3A, there is an additional mod that the 
KREF3 Reference Oscillator should undergo.

Re: [Elecraft] K3 on 2 meters

[Phil Hystad via Elecraft]

OK, I am curious…

Why was not this reference clock board not built into the 2-m option board in 
the first place.  Overall I can’t imagine that the net cost would be as much as 
designing and separating out an optional PCB and all that goes along with that 
as the combined cost of the 2-m option and reference clock now.

After all, it was recommended for SSB and CW use.  Now, I suppose that there 
are possibly people in this world that would buy the 2-m option only for FM 
comms but given that a nice separate 2-m FM rig would be cheaper it doesn’t 
make sense to me to add something like that to the K3/K3S.

Important fundamental concept, Clay, that I learned in an IEEE EMC 
workshop. DC follows the path of least RESISTANCE. AC follows the path 
of least IMPEDANCE. If there is a transmission line with, for example, a 
chassis in parallel with the transmission line return, above about 1 
kHz, all the return current will be in the transmission line, NOT in the 
lower resistance chassis.


That's because the return patch through the chassis includes a lot of 
INDUCTIVE REACTANCE, which increases in proportion to frequency, while 
the path through the transmission line, if matched, never rises about Zo 
of the line. The whole point of using the transmission line is to reduce 
noise and crosstalk. It's only effect on DC (as compared to the chassis 
path) is to slightly reduce the DCR of the return path by adding the 
transmission line return in parallel. With coax, of course, the shield 
is the return. Wtih 2-wire line, one conductor is the "hot" lead, the 
other the return. AND -- 2-wire line and coax are no different in this 
regard! The KPA500, for example, uses twisted pair for wiring from the 
input coax to the amp input stage.

Re: [Elecraft] K3 going expeditionary

[Clay Autery]

Yup  When I did my alternator and battery upgrade (including a 
complete replacement of the power/ground cables with much heavier 
cable), for my stereo install, I discovered that very thing  even in 
a TRUCK with a frame.
I mapped out and installed massive ground continuity cables from every 
metal body part to the frame, and finished up by MEASURING the 
resistance from point to point all over the body, bed, cab, frame, and 
engine to insure that the entire ground plane was continuous and super 
low resistance.


Maybe overkill, but it works great, and it gives me comfort to know that 
vibration dampening and oxidation aren't compromising the counterpoise.


Side bonus, was that the 12VDC ground plane was so good afterwards, that 
I have been able to take out a lot of the home run grounds from a bunch 
of lights, et al... ofsetting weight gain by some bit.

My thanks to everybody.
It is rather overwhelming for just a Sunday afternoon of portable operation
in remote counties powered by the car.
I will really want to keep simple in those terms.

Reading through all this several times.  Thanks to all who contributed.

Re: [Elecraft] K3 going expeditionary

[Jim Brown]

Of course it applies. Mother nature does not pay attention to what we 
CALL things. It is quite common for DC and mains power to carry AF and 
RF currents. That's how most noise is radiated -- as a common mode 
signal on cables connected to equipment that includes noise sources.


BTW -- as Vice-Chair of AES Standards Committee for 20 years, I HAVE 
studied this stuff extensively, along with colleagues around the world 
with excellent engineering chops.

Re: [Elecraft] K3 going expeditionary

RFI on audio, agreed. Noise on DC, not so much. Routing is the most
important factor for DC power. It is hard to get enough turns on the proper
size wire to make a difference.

Re: [Elecraft] K3 going expeditionary

[Clay Autery]

IF it were me, I would run two NEW, 10GA or better high strand count 
wires (twisted by hand or drill) from the battery to the cabin with 
appropriate fuses in BOTH POS and NEG lines, and the Anderson PP 
connector on the end.
Ideally, I would also put a SPST switch in the POS (my pref), or a DPST 
switch across both leads so that I could turn the power off there for 
connection purposes (optional).


This gives you the ability to 1) power the K3 with Key off, engine off 
if desired, and 2) gives you a big, shortest run dedicated to the radio.
Additionally, it gives you a twisted pair, AND the ability to put chokes 
wherever you might need them to quiet down the power source from 
possible noise from the vehicle.

Re: [Elecraft] K3 going expeditionary

[Rick NK7I]

Not only is the accessory circuit shared with others, it is often loaded 
with noises from the electronics in the vehicle.  They can harm both 
your RX and TX signals.


It takes a little time to run #12 ROMEX (with 40 or 50 A mobile, 
self-resetting circuit breakers at the battery to protect the wire, 
fuses for radios AT the radios; both positive and negative) but the 
returns are worth it.  You'll have to remember to turn the K3 OFF each 
time you start the engine; the wandering voltage could cause harm or 
scramble the settings.  Also bond to chassis AT the K3 to keep some RFI 
down...


*IF* you have a newer vehicle that measures current draw and charging 
rate at the battery (sometimes via the negative pole), you'll want to 
use that sensor point for negative connection; not at the battery.


That's the super quick description, to start a foundation of proper set up.

Re: [Elecraft] K3 going expeditionary

[George Thornton]

Concur.  

The K3 can in my experience be vulnerable to voltage drop which can happen with 
a questionable power source.  

For a rig like the K3 you should draw straight from the battery.  You can add 
some additional protection in a mobile setup by incorporating a voltage 
regulator In the circuit just before the K3.

You could do that. I wouldn't advise it for other reasons. Why don't you

This used to work, back in the K3/0 non-mini days. You'd connect the
two using a null-modem cable, and invoke "terminal mode" with a long
press (~5 seconds) of the MENU button. The manual for the "mini" is a
bit vague, but it looks like its connection to the RRC box is TTL, not
RS232, so to connect that to a K3 directly might require a level
converter interface.

The issue is how to get all of the connections from the K3/0-Mini to the K3.  
The “Elecraft K3-Remote Owner’s Manual” (Revision D, April 3, 2014) discusses 
two methods of installing the K3-Remote variants:

1. Via the RemoteRig 1258MKII approach that connects to your personal K3 at the 
ham shack and a second RemoteRig to the K3-Remote.  This is what I’ve done.

2.  Using the K3-Remote via a PC through a USB connection.  This is meant to 
provide access to on-line remote Ham rig services such as “Remote Hams’.  I 
have no idea what interface(s) are installed at these sites to their K3s.

I don’t know whether the two Remote Rigs would work directly connected through 
a reverse cable, you’d probably have to connect both to a LAN where both 
devices would be assigned a local IP address (either static or dynamic).

Re: [Elecraft] K3 boards

[NE9U - Scott Jasper]

Ok greatgood to know.

I am thinking of replacing my OBSOLETE FT1000D second radio so2r for another k3.

If anyone knows of a well filtered one at a reasonable price, I'm in the 
market.  Have one hot lead locally I'm waiting on.

Re: [Elecraft] K3 Diversity RX question

[Dale Boresz]

Jim,

With BOTH 'Split' and 'Diversity' engaged, you will only be able to listen
to VFO-A, although VBO-B WILL be your transmit frequency. In other words,
you will be listening to the DX on VFO-A with full benefits of Diversity.
However, you can press and hold the "REV" button on the K3 which will swap
the VFO A/B frequencies, at which point you will be hearing the pileup in
full diversity and your VFO-A cursor will change to your XMIT frequency.
You will tune through the pileup with your main VFO (VFO-A) to figure out
where you want to transmit, and when you release the "REV" button you will
again be listening to the DX station on VFO-A but you'll notice that your
P3 VFO-B cursor (and TX frequency) will be wherever you placed it using the
VFO-A knob while depressing the "REV" button.

I don't claim that this is the ONLY way to accomplish this, but it is the
way I have been doing it for years. A downside is that you will not be able
to simultaneously hear the DX in one ear while hearing the pileup in the
other. This makes sense though since diversity allows you to listen via two
different antennas, with one antenna per ear. It takes a bit of practice,
but it works well.

73,
Dale - WA8SRA

Re: [Elecraft] K3 Diversity RX question

[Victor Rosenthal 4X6GP]

Yes. When you use diversity you are actually not using the VFO B 
synthesizer for the second rx. They are both fed from synth A. VFO B 
remains available for transmitting.

I do this all the time.

When using diversity what happens to the ability to do Split on the K3?

Can I still listen to the pileup on VFO B and transmit on the VFO B
frequency?

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

[Grant Youngman]

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

The K3 can get antennas in a bewildering collection of ways. If the
RX antenna switch is on -- and this was my way of getting on reception 
-- it might be your problem. The K3 can also send received

signals out on one of the BNC connectors and expect to get them back
on another.

I recommend a careful reading of the manual, perhaps in PDF form with
a search for "antenna". The manual is downloadable from the Elecraft
web site.

Re: [Elecraft] K3 Issue

[Steef PA2A]

Ronnie,

a few months ago I had the same problem when my K3 #1184 was on for 
about an hour. No RX, and no TX output. The KSYN3A synthesizer seemed to 
have lost contact with the rest of the K3 and it gave different error 
codes. The problem has finally been solved by disassembling the complete 
K3 and SUBRX with all of its TMP cables, and I suspect one of these 
cables caused the problem. An intermittent contact of the KREF3 
reference oscillator could also be the cause.


73s Steef PA2A


From: Ronnie W5SUM 
To: "Elecraft Reflector" 
Subject: [Elecraft] K3 Issue

Good Morning

I purchased a used K3 a couple of weeks ago and received it last 
thursday. I
hooked it up and it worked GREAT.  Used it for SSB and CW contacts on 
80M

and ssb on 10M.  Shut it down about 8pm last night. Turned it on this
morning, and it has white noise audio but receives no signals at all.
Nothing showing on the S meter either not even noise.   NO POWER OUTPUT
either.

Has anyone every seen a sudden failure like this?  I'm heartbroken as I 
am

fearful of a astronomical repair charge from Elecraft and the person I
bought it from is offering no warranty at all and since it was used I
totally understand that part.

Thanks in advance

The K3 can get antennas in a bewildering collection of ways. If
the RX antenna switch is on -- and this was my way of getting on
reception -- it might be your problem. The K3 can also send
received signals out on one of the BNC connectors and expect to
get them back on another.

I recommend a careful reading of the manual, perhaps in PDF form
with a search for "antenna". The manual is downloadable from the
Elecraft web site.

  Good Morning

Re: [Elecraft] K3 / MH2 PTT problem

[Don Wilhelm]

If you are getting an ERR PTT when you power on, then either the key 
(Paddle) is closed or the PTT in the microphone is stuck in the active 
position.


Remove the hand key, paddles, any PTT switch or footswitch and 
microphone to see if the Error goes away.


If things are then OK, plug each one in one at a time and do a power 
cycle - when the Error message occurs, you will know that the last thing 
you plugged in is causing the problem.

I am trying to figure out if there is anything to check besides taking 
the microphone apart and cleaning/de-oxing it.

3 "bars" on the rf meter.  That looks to be 20 to 25 watts.

If I readjust the level, up or down, it takes another 30+

seconds and it will not go over 3 "bars".

Anyone offer any suggestions?

Re: [Elecraft] K3 SSB Quality in Transmit

That's been my experience as well on the few times I get on SSB.  
Completely unsolicited reports, with both a CM500 and a Heil Proset with 
the iC electret mic.

I wanted to pass along to you Elecraft engineers my experience during 
this event.  I am a CW-only op for the most part and really never hear

reluctantly to SSB and swinging down that odd foam thing which usually 
resides over my head I received numerous comments like: "Best signal 
of the day here, very clean audio!" and "Wow! It sounds like you are 
in the room here, excellent audio"  and "Your signal is audible above 
the pileup because it is so clear!" and a few others which really 
surprised me.  Who knew you could actually send your voice through a 
ham radio!


I take no credit for any of this other than turning the rig on. I 
heard many crappy sounding SSB signals during this event, some even 
difficult to understand despite good signal strength and I appreciate 
Elecraft making the K3 operate so well, I believe it was a real 
advantage.  I can only hope the K4 will build on this quality!

No. At field it’s batteries. At home an Astron 35m linear or any or several

The field setup may be one or two AGM batteries. Nominal voltage 12-12.8 volts.

Re: [Elecraft] K3 DATA setting

[James Bennett via Elecraft]

When you press the mode button on the K3, it should cycle through: 
USB—>CW—>DATA—>AM—>FM—> and then back to CW. What does your do?

If it indeed displays DATA and you leave it there, then push and hold the 
AFX/Data MD button, turning the VFO-B knob should cycle you through: Data 
A—>AFSK A—FSK D—>PSK D—> and then back to DATA A. Your result?

Re: [Elecraft] K3 DATA setting

[John McBride]

Thanks for the replies. I am not using split mode, and am trying to make the 
change from USB to DATA A in the individual bands of 20 and 15 meters. Yes, the 
change was made successfully for 40 meters from LSB to DATA A. Any thing else I 
should check? Knowing me there is probably an easy answer.

John,

Mode is a per band setting.  So do not expect it to be 'sticky' from
band to band.
Once you go to the band for operation, you should be able to change the
mode.

Re: [Elecraft] K3 Utility Restore config error

[gt-i]

Thanks for the idea, unfortunately the problem persists. This makes me a 
bit more nervous than before as I have done quite a bit of upgrading 
lately (144MHz, Reflock, TCXO) and I had a fault in the tuner (capacitor 
blown), and now the refclock is off by 220Hz.


Did anybody else had the problem before and knows the fix?

tnx for sharing

Re: [Elecraft] K3 Audio Peaking Filter

[John Gibson]

Hi Bill,

Thank you for your query. My K3 has the 400 Hz CW roofing filter. Because of 
currently challenging conditions, I usually set my K3’s width control to 25 Hz. 
My preferred audio frequency is 600 Hz. 

Those were my K3’s settings when I tried to check into the Elecraft CW net last 
evening.

I engaged the APF after nothing else worked. Following N6KR’s recommendation, I 
used fine tuning (1-Hz steps). I tuned around slowly near the expected net 
frequency of 14.050 MHz and suddenly heard net control Kevin KD5ONS calling at 
14.05045 MHz. 

I recognized Kevin, as I often do, by the rhythm of his sending. He was loud! 
When I turned off the APF, he vanished.

I believe that tuning slowly in 1-Hz steps is the secret to making the APF 
work. 

I hope this helps.

73,

John, no8v

Hi John, that is fantastic!!  I have never experienced anything near what you 
describe with a K3s or my original updated K3 SN 00069.  I find that a very 
narrow 200 hz CW filter works best for me in those conditions you so apply 
described.  Tell me more, do you open up the filters to kHz?  Please describe 
how you set this please.  I have tried all prescriptions I have read on this 
reflector and had no joy with any of them..perhaps I need some schooling?

We just added dual-passband APF to the K4. It's very effective at higher code

Unfortunately, the APF is too narrow for 160m with all the lightning noise.
As I recall, we've been promised wider selectivity choice(s) but nothing ever
