Re: Elecraft Digest, Vol 167, Issue 9

[Elecraft mailing list]

Alan,


I have the KX3, KXPA and KPA500, but not the KAT.  Instead, I am using the LDG AT-1000ProII.  


With the KPA off or in standby mode, I put the KX3 into XMIT and auto-tune the LDG.  Then, I hit ATU TUNE on the KX3.  The power indication on the KX3 will not include the KPA output, but it does indicate the drive power.  So, I set the KXPA for the proper amount of drive for the KPA, typically between 30 and 40 watts for 500-600 watts output.



The KX3 can also drive the KPA directly, without using the KXPA.  With 12-15 watts drive from the KX3, the KPA will put out 200-250 watts (typical).

I really appreciate the wide variety of questions and topics that arise on this reflector about the K3 which includes problems encountered while using a K3. ?Recently, I learned some valuable information about how to setup my K3 so it receives FT8 signals better, and on how to setup my K3 transmitter so it keys faster. ?(turn the VOX off and use PTT) ?Though I'm mainly a contester, and then a DX'er, FT8 is quickly becoming a great tool for working DX. ?Since I'm mainly a contester, I'm looking forward to the day when I can operate a FT8 contest. ?But for now, I'm very happy to use FT8 on my K3 as another tool for working DX.

Thank You Elecraft for allowing a wide variety of topics relating to the K3 on this Reflector.

Phil,

Questions about your K3 and any other Elecraft product are quite
welcome. This reflector covers all Elecraft products as well as
problems owners encounter when using them.
FT8 is causing some confusion for owners new to digital modes, and that
is why it is currently producing a lot of questions - we are trying to help.

Stick around and you can glean a lot of information from this group, not
only about your K3, but a lot more too.

I believe at least some of the DSP filters in the K3 are FIR (Finite
Impulse Response) ones, which should be phase linear.  The roofing
filters will not be phase linear, so I would think you could get away
with using a narrow DSP filter, as long as you used a relatively wide
roofing filter.

This will still leave the ADC, and the analogue circuitry between the
roofing filter and it, open to overloads, but will protect the sound card.

I teach modern jive which is now far more popular than ballroom dancing
which I trained in in my 20's.  Now in my 70's this has a very healthy

Thanks Don.

The amp ALC line uses an audio oscillator and diode to generate the negative
voltage, so I can leave it out or add an extra gate for 5V or GND.

Alan,

I would strongly recommend you use the Transmit Inhibit in the ACC
connector instead (pin 7).  See page 21 of the K3S manual and page 66
for the menu (note it is a Tech mode entry).

If you do not have a contact to either ground or +5v in that amplifier,
You may have to devise an intervening circuit to provide either ground
or +5v to ACC pin 7.  You should not apply a negative voltage to that pin.

Hi Peter.

I would have used the K3S power control anyway, but I'll modify the
circuitry to accommodate the K3S TX Inhibit.

A QSO should be possible on 2M (even without the linear). My take-off to the
West is good and the slightest lift in conditions seems to get me to West
Wales etc.,

Hi Alan,

I would strongly recommend that you do NOT use ALC for any form of
control signal or drive limiting.  For control use the inhibit on the
acc connector and for power output use the K3 pwr control.

Look forward to hearing you on 2m.

They arrived Thursday.  Between Thursday night and Friday morning I built
the amplifier.  Thursday afternoon I built the tuner.  No issues with
either except the tuner was missing a silicone thermal pad.  An exchange of
emails quickly determined I could use one I had on hand.  Nice to get quick
responses from people who know the product!

The amp was used for the entire contest weekend without a hint of trouble.
I tried to watch the power out and keep it out of the red.  Even when I was
on a small run the temp never got above 52 C.

The tuner worked great as well, only a couple of times it refused to find a
match when I was using low band antennas well outside their sweet spots.
Nothing a button push wouldn't cure.

Many thanks to the whole Elecraft gang for the great products!

Thanks for your help Graziano,
I'm using a cable made by Dan Tassel/SPE and I think it is the same wiring as your diagram shows.? ?
I did finally get it working? this morning.? ?After comparing your diagram with my wiring I was looking at software port configuration more closely and I noticed that N1MM+ recommended having stop bit set to 1...... I had it set to 2.? ?I changed it and everything started working.? Also started working when I changed it in the dxlab commander software.
My takeaway is that at the faster baud rates stop bit setting is not so fussy.? ?At the slower baud rates it IS fussy.??

Message-ID:

Content-Type: text/plain; charset="UTF-8"

A little help / guidance please.

I have a Kx3 w/ Kxpa100 and soon I will be adding a Kpa500 / Kat500 to this mix.

When you add a Kxpa100 to a Kx3 you set the power on the Kx3 from
0-110w.  If you click tune on the Kx3 it tunes the tuner in the
kpa100. Full integration

How does all this work once you add the 500?

Once you add the 500 to the mix does the Kx3 now show 0-500? Does the
Kx3 "control" the 500? What is the wiring path for this?

Some of its obvious; the tuners in the KX3 and the KXpa100 will need
to be disabled, RF out of kpa100 to RF in on the 500.


Thanks in advance,
Alan

Alan,

Yes, set the KXPA100 tuner to bypass - switch on the front.

You will be using cabling as shown in Figure 4 page 11 of the KAT500
Owner's manual.  The "output on transceiver that provides closure to
ground on transmit"  is the RCA jack on the rectangular box in the cable
between the KX3 and the KXPA100.

Note that the RCA cables which provide keying for the amplifier MUST be
routed first through the KAT500 and then to the amplifier - that allows
the KAT500 to disable keying the KPA500 when it is tuning.

Don W3FPR

They recommend turning agc off and manually adjusting RF gain.

There is more to the mode than pushing a button and waiting for your

Subject: [Elecraft] ERR AT3 on K3
Message-ID:
        <[hidden email]>
Content-Type: text/plain; charset="UTF-8"

Hello all:

Over the weekend I was getting an ERR AT3 on my K3 when I first turn on the
radio. I did read in the manual about removing the KAT3, but decided just
to try setting the Config to "not inst" and the message no longer appears
during power up. The radio seems to work just fine without the tuner
"installed".

Is it likely the KAT3 is the problem or could it be something else? Also
wondering it is possible to have the KAT3 repaired.

Thanks,

Jed

I misread the title and thought it was hobbies for us men over 75 until
I saw parkour listed (which I couldn't have done even when I was younger
without falling on my face.? I have done over half of those activities
however.

Jed,

I would suggest unplugging the KAT3 and re-inserting it.  Sometimes that
will wipe the contact pins of any oxidation and correct the problem.
Consult the K3 Assembly manual to see how to install the KAT3, reverse
the steps to remove it.

Repair is possible if you are capable of troubleshooting to the
component level.  The schematics are available for download from the
Elecraft website.

If that does not resolve the problem, then contact [hidden email]
for further actions.

If your K3 does not have gold pins on the front panel, and they
are getting oxidized, strange error messages may occur on
power-up.  Either do the gold pin mod, or hit the old tinned pins
with DeoxIT.

It very well could be the pin connections.

This weekend I started intermittently losing TX audio and when holding
TUNE, it would go into TX, display 0 watts, and put out no power.?
Shutting the K3 and power supply off and turning everything back on
seemed to correct the problem once but then it started doing it again.?
I removed the top cover and started checking connections of the 'TMP'
cable connections. Pushing on some of the ones on the KREF3 board made
the problem come and go.? It didn't seem to be any particular one
though.? I ended up removing the KREF3, cleaned the (tin) pins, put
everything back together and it has been working fine so far.

Subject: [Elecraft] Elecraft K3s and FT-8 in an evening
Message-ID: <[hidden email]>
Content-Type: text/plain; charset=utf-8; format=flowed

I had a goal to take a shot at Digital modes after the 2017-2018 Major
Contest Season, which ended Sunday with the close of ARRL DX SSB.? So,
Monday I was determined to make as much progress as I could with
something digital.

My first effort was to try MMTTY, since it was already somehow
integrated into my current logging software, but I'm probably a little
more impatient than the program designer expects and I shortly began
looking for alternatives.

I have heard a lot about FT-8 so I did extensive research for two
minutes on the Internet and downloaded the WSJT software.? This includes
the mode everyone is talking about, FT-8.? And the interface was a
little less intimidating, so? I thought I'd give it a try.

First I needed to interface my PC with my K3S audio.? I never worried
about this, but I wanted to have this for next contest season to use
with N1MM+ Logger, so it was an acceptable priority.? What surprised me
was how easy this was to accomplish.? The same cable that provides CAT
Control also support bi-directional sound, so there are no analog audio
cable to attach.? I simply select USB CODEC both ways and did some test
recordings in Audacity to see if I could hear the radio. Yes, main
receiver on left channel and sub-receiver on the right channel, so all
is well.? Heading the other way, I needed to adjust things a bit.

I added two important pieces of hardware to the interface between the
K3s and my computer.? The first was the N6TV Y-Box, which permitted me
to have more than one item connected to the K3s ACC connection on the
rear panel.? The second is the W1AN TTL-Serial adapter, which is
designed to mate to the ACC jack, as well.? I leveraged the W1AN adapter
for PTT control and used the Keyspan USB-to-serial adapter to connect
back to the PC.? That could probably be cleaner, but it works flawlessly.

So, I had the radio listening and keying, but not making any noise.?
What I missed is the LEVEL control that you get in DATA mode when you
fiddle with the MIC level knob.? I moved it up until I had three or four
bars on the ALC meter, and it seems fine.? In order to test the settings
I decided to make a few contacts and after my first 50 QSOs I thought it
might be good to post something here for those who, like me, are just
starting out in digital.

One obvious thing after making these contacts: it's different.? First,
it felt disconnected from "real" radio. I'm listening to the audio in
the headset hanging under the desk, but I don't have to interpret
anything - the WSJT-X software does all that.? I just pushed a couple of
buttons and I had a contact (most of the time, except for that 5T2 that
I didn't get).? But gradually, the actual signal reports coming back and
forth got very interesting.? "Why the 10db difference here?" and "Hey, I
was 1db better than that guy." and so on.? And that's how it came about
I couldn't stop until 50 QSOs. Each one a new WAS Digital or a new DXCC
Digital.? Neat stuff.

I will try other digital modes, but I want to dive a bit deeper into
this software, try more bands, see the singnal reports under different
conditions and understand things a little better.? This is educational,
and fun.? And, I met my goal of going digital in one day.? Many thanks
to N6TV and W1AN and others for their support and encouragement, and to
Elecraft for making this so easy.

Enjoy your day!? 73, Byron NZ3O K3s #10072 NZ30/qrp KX3 #4816 FT-8 Fan

Hi all,

No, the major contest season has not ended. The WPX contest is still to go
at the end of this month.

Curious what others are using for a USB interface from the KX3 to the
MacBook Pro with all USB-C ports.

Don... I removed the KAT3, cleaned the contacts as you suggested. Seems to
be working fine for now. Thanks for the tip.

Dave... I previously had problems with the front panel pins. They have
since been replaced with gold pins. Haven't had further issues.

Mike... thanks for your reply as well. Sounds like it may be a good idea to
check all the pins in the rig at some point.
