[Elecraft] Elecraft CW Net Report

[kevinr]

Good Evening,

    Two good nets with decent conditions.  QSB was pretty deep but slow 
enough not to chop up words.  Reports came in on the last few days of 
good weather, the gang at Pacificon, working Ducie, tuning up the snow 
blower, recovering from Michael, visiting the PNW when it's not raining, 
and just spending time on the planet. Some mention of Elecraft gear but 
that's normal.



  On 14050.5 kHz at 2200z:

K0DTJ - Brian - CA

K9ZTV - Kent - MO

K6XK - Roy - IA

W0CZ - Ken - ND

K4TO - Dave - KY

K4JPN - Steve - GA


  On 7046.5 kHz at z:

K4TO - Dave - KY

K0DTJ - Brian - CA

K6PJV - Dale - CA

W6JHB - Jim - CA

W0CZ - Ken - ND

WM5F - Dwight - ID


   The time change is another week in the future so I get more time to 
think about the transition to winter.



Stay well,

    Kevin.  KD5ONS

[Elecraft] Pacificon

[Wayne Burdick]

Another Pacificon has come and gone Seems like a great time was had by all. 
That certainly applies to those of us at the Elecraft booth, where it always 
feels like a reunion.

I’d like to thank everybody who stopped by to kick the tires, tell stories, or 
just introduce  themselves for the first (or Nth) time. Hard to keep track of 
so many great customers and acquaintances, but we try. 

I got stuck in traffic somewhere in deepest Hayward, California, and missed the 
opening hour of the exhibit hall on Friday. I understand all the AX1s we 
brought sold out within a few minutes. We’ll be better prepared in the future.

Thanks for all the great ideas for future products and for improvements to 
current ones, as usual. 

73,
Wayne

Not surprising -- trans-equatorial propagation is what's left at this 
stage of the sunspot cycle, there's not much of it, and you've got to be 
there at the right time. AND they're running 600W to very good antennas. 
The two stations I copied were from LU, also trans-equatorial.

Re: [Elecraft] K3s vs KX3 Quedtion

[John W2XS]

Here are some things that mattered to me when thinking about the KX3 vs. K3
for home use:

Features that the K3/K3S has that the KX3/KX2 does not have:

1. No messy cables on the desk. This gives a cleaner look to the operating
position (IMO).
2. Coverage of the AM broadcast band as well as full shortwave coverage.
Important to me to reduce (someday) the need for other radios.
3. Excellent roofing filters. I don't know how the KX3 roofing filter system
compares to the K3 xtal filters.  But dialing down the selectivity to under
200 Hz and having that 200 Hz xtal filter click in is an awesome experience.
4. Built-in low-noise amplifier for 12, 10, and 6 meters. 
5. Full-featured second receiver option. Diversity reception is amazing.

The KX2 vs. KX3 decision revolved mostly around size, 160 and 6 meters,
roofing filter, and 12 vs. 15 watts. The block diagrams are very similar.

I have the K3 for home use (upgraded to "almost" a K3S). Since giving my K2
to my brother, I now have a KX2 for portable/QRP work.  I am happy (but do
miss the sound and looks of the K2).

Have you listened or made QSOs on 12 or 10 recently? Occasional E-skip 
is pretty much what there is, and there's not much of that. I had my K3 
parked on 12M FT8 and a good antenna for most of a week and decoded two 
stations (days apart). Both called CQ and didn't work anyone. In another 
year, 15 will be like that.

Yes, but -- folks are selling a K3 to buy a K3S, and, IMO, a K3 with the 
new synth board and the new transverter board is as close to a K3S as I 
need to be. That's what I did with my vintage K3s. A loaded used K3 with 
those boards added is several $K less than a new K3S.

[Elecraft] K2 driving an amp

[Brian]

Quite some time back - like about 12 years - on a boring February day that to 
my memory was my birthday and I was killing time waiting for the in-laws to 
arrive for dinner I hooked up my K2 to a Technical Materiels Corporation 
milspec linear amp... PAL 350. This amp is meant to be paired with a low output 
TMC exciter (around 1 watt) and is conservatively rated at 350 watts output.

I think I used a Dow Key relay for T/R, dialled down the K2 to a low power 
level with an attenuator in line for good measure, and about 6 arms and hands 
to do all the manual switching of the Dow Key relay 110 volt wall switch device 
and turning the amp to Operate etc. The amp has an amazing number of fail-safe 
triggers (I guess for fumble fingering operators and newbie GIs, HI) so 
anything weird or more power than it liked...it just tripped off the safety.

It was a resounding amount of weird fun and I worked Hawaii on 'fone for I 
think my first and last time... on 20m.

Not for the faint hearted or something I would normally do in the regular 
operation of the shack. But I had time to burn. And definitely not QSK 
operation.

This would of course be easier with a rig like the K3 with an  key-line output. 
Heck, even my tube based Johnson Ranger has a key line output in its T/R and 
receiver mute box. I still think I need a Private to run the TMC amp's knobs, 
bobs and whistles though.
Mind you, you should have seen the TMC  kilowatt amp that partially devoured my 
basement for a while... almost as big as a PDP-11 computer frame. Long gone, 
heavy beast. Did fit into a Volvo station wagon though.

Re: [Elecraft] K3EXREF issue? K3

[Gary Smith]

Ed,

Thanks for the reply. I do need an 
oscilloscope. The only frequency counter 
at this QTH is this K3, my K3s is at the 
factory for an issue with SSB. 

That said, there does appear to be a 10MHz 
signal coming from the GPSDO. There's 
enough bleed-through that when I tune to 
10MHz I can still pick up the ticks from 
WWV, however removing power from the GPSDO 
and the signal drops considerably. I 
connected 10' of wire to the center 
conductor of the SMA and the signal in the 
K3 increased considerably and it was dead 
on top of WWV. So I'm feeling it's putting 
out a signal at 10MHV but the strength or 
condition of the signal, I have no way to 
tell.

Looking at the info on the K3EXREF, the 
Tech MD is on, REF CAL is displayed and I 
need to engage keypad #2 to switch between 
the EXREF being in or out, I have it 
switched in. No asterisk.

I have not been inside the radio since I 
started using it a week ago and the 
asterisk was flashing at that time. I 
saved the current configuration and loaded 
the configuration that was good the last 
time I used the radio and that didn't 
help. I can't imagine the cable in the 
radio failed without any mechanical 
action. I'll have to take a look and see 
if anything has become somehow dislodged 
though it's been just sitting on the 
table.

I was hoping it was something in a setting 
that might have been altered and it seems 
like that's not it. Thanks again for the 
assistance.

73,

Gary

Joel,

For "wake on LAN" to work the network adapters on each end of the LAN or 
WAN connection (wired or wireless) have to be set to send and receive 
"wake on LAN" packets.

Re: [Elecraft] K3s vs KX3 Quedtion

[Bob McGraw K4TAX]

Terry:

My first thought, KX3 over K3S, is portability.   If you have the space 
and don't usually operate portable, the K3S is the choice. As to price 
that is always way down the list and secondary with me in a much as I 
demand performance, do not operate portable, have the space for the station.


Sitting on the desk is my K3S-100 , P3, KPA500 and KAT500.   All factory 
assembled units.  I do work SSB, CW and Digital modes.  I don't think 
there is a finer radio or system on the market today .at any price.

I bought a KX2 for portable ops as a result.

I guess I’ve drunk too much Elecraft Koolaid because I keep looking at the K3s. 
 To buy a fully outfitted K3s and P3 would set me back about $6k.  I am 99 
percent a cw operator. Once I became proficient in CW several years ago, all 
digital modes ceased to be of interest, as did SSB.

So with that background,  I would like someone with both the K3s and KX3 to 
tell me what features the K3s has over the KX3 that would realistically make 
that $6,000 purchase worth doing.

Thanks so much!

[Elecraft] Function XVn RF and XVn OFS ranges

[Bjorwal]

Hi,
Regarding external Transverters, the functions XVn RF and XVn OFS have to be
used.
The XVn RF can only be set to a full MHz, and the XVn OFS can be set to
±9.99 kHz.
If You have a transverter with a not so good crystal, that will not
oscillate stable enough on the intended frequency, You have to use these two
functions. For 10.368 GHz the crystal multification will be 96 and for
24.048 GHz the factor is 192. To have a crystal that is below the ± 9.99 kHz
up on these bands, you have to pay a fortune for this, if you find a
manufacturer that can deliver these with that tight specification...and that
Your Heater / Oven is working OK.
(Just 4 info, a 100 MHz crystal is normally of a 5th overtone cut, which
means an actual multiplication factor of 96 x 5= 480, and 192 x 5= 960. A
1ppm crystal can be off by 23.9 kHz at 24GHz. At 47GHz this will be 47
kHz.). 
Normally a crystal has an accuracy of some 0.005%, which is 50ppm. 
For 10,368 MHz this will be 518 kHz ! 
Suppose the offset is +55 kHz.
How to set up the KX3 to include this figure, so the frequency readout is
the actual frequency You want to operate upon ?
This will not work, unless:
XVn RF can be set to steps in 0.1 MHz and XVn OFS can be set to ± 50.0 kHz. 
or
XVn RF in 0.2 MHz steps and XVn OFS ± 99.9 kHz.

This will give You the chance of letting the frequency display be within
100Hz of the actual output, regardless of the wanted offset.
 
Is there room for a F/W modification ?
Rgds Bjoern

Re: [Elecraft] K3EXREF issue? K3

[Edward R Cole]

Gary,

Well first thing I would check is whether 10-MHz is present at the K3 
EXREF sma jack.  If you have a freq counter check for correct 
freq.  No counter then use a radio that can tune 10-MHz for presence 
of signal on correct freq.


Check for adequate reference level (I run 10mw which is more than 
adequate; probably will run with 3mw to 5mw).  If you have no 
milliwatt meter then use an oscilloscope to measure RF voltage.  Pav 
= Vrms^2/R  or Vrms = 0.3535*Vp-p*probe multiplier.


From: http://www.ab4oj.com/test/pwrmeas.html
Pav = 10*10^-3 = 0.01 w , Vrms = sqrt(Pav*R) = 0.707v, Vp-p = 2,.828*Vrms = 2v

If you are using a 10x probe Vp-p = 0.2v; Be sure to measure voltage 
across 50-ohm load connected to the REF input.


If this is low or nonexistent try a different cable from the 
GPSDO.  Also check 10-MHz output at the GPSDO.


My guess either you have no 10-MHz ref signal or its off 
frequency.  If that is good then recheck configuration to enable 
EXREF.  Still bad: then check internal coax from EXREF connector to syn  board.

Using a K2 alone as driver for the KPA500 is the question.  There must be 
an amplifier keying line somewhere in the K2 circuitry, since it can key a 
KPA500 [should have read KPA100] in the two-box "twins" configuration; but 
there is no mechanical output for it.  Anyone done this who can help with 
ideas?  

What kind of output from the KPA500 is possible with a barefoot K2 driving 
it?  Anything else I should know before trying this out?

The band data is not a problem in either case, since the KPA500 has a 
one-dit sensing circuit which will be adequate.  (It also has band selection 
buttons, of course.)

Tnx, as always, for any advice,

Ted, KN1CBR

[Elecraft] K2 driving KPA500 / KAT500

[Dauer, Edward]

 Having used the KPA1500 long enough to be confident that mine has no obvious 
bugs, I am trying to decide whether to keep my KPA500 / KAT500 or put it up for 
sale.

One possibility would be to use the 500s with a K2.  I have a K2 with the 
integral KPA100, and two without.  The K2/100 has an RCA jack for the amp 
keying line which should make things easy - just connect one end to the KPA100 
and the other to the KPA500, yes?  

Using a K2 alone as driver for the KPA500 is the question.  There must be an 
amplifier keying line somewhere in the K2 circuitry, since it can key a KPA500 
in the two-box "twins" configuration; but there is no mechanical output for it. 
 Anyone done this who can help with ideas?

[Elecraft] K3s vs KX3 Quedtion

[Terry Brown]

My first Elecraft rig was the K2,  I then bought what has become my base 
station; a fully loaded KX3, KXPA 100 and PX3.

 I got tired of all the cable interface problems with KXPA not working and the 
cursor not showing up on the PX3 if I took the KX3 portable (always a lot of 
replugging and reseating cables to finally get it to work. )

I bought a KX2 for portable ops as a result.  

I guess I’ve drunk too much Elecraft Koolaid because I keep looking at the K3s. 
 To buy a fully outfitted K3s and P3 would set me back about $6k.  I am 99 
percent a cw operator. Once I became proficient in CW several years ago, all 
digital modes ceased to be of interest, as did SSB. 

So with that background,  I would like someone with both the K3s and KX3 to 
tell me what features the K3s has over the KX3 that would realistically make 
that $6,000 purchase worth doing. 

Thanks so much!

Terry, N7TB

Re: [Elecraft] K3 vs. KX3 with wsjt-x

[Bob McGraw K4TAX]

Make sure you are using only one PTT method.  CAT  or VOX but never both.  I 
prefer CAT as any signal or any noise on the audio line will trip the VOX and 
thus hold it in transmit.

Re: [Elecraft] K3 vs. KX3 with wsjt-x

[Bill Frantz]

I indeed had MIC BTN on, and turned it off. I the KX3 still 
didn't go into receive when I pressed the "Halt Tx" button. (MIC 
BIAS was already off.)


Another issue I didn't mention before seems to have gotten 
worse. Sometimes pressing the "XMIT" button on the KX3 doesn't 
take it out of transmit mode. When I press it it stays in 
transmit. Press it again and it still is in transmit. It finally 
goes into receive when wsjt-x gets to its receive phase.


I am still having problems developing a mental model of what is 
actually happening here. Maybe I'll have to download the wsjt-s 
source code and start reading code again. But that's what I 
retired from years ago. :-)

[Elecraft] AX1B for 10/6 meters?

[Wayne Burdick]

Hi Jim,

The 17 meter switch position allows efficient operation with an ATU on 17 and 
15 meters. While it may be possible to achieve a low SWR on higher bands, the 
losses would be higher. 

A better approach would be to build a different base unit with smaller 
inductors. For example a 10 and 6 meter version would work very well on both 
bands. Let’s call it an AX1B for discussion purposes. This might appeal to 
Technician class licensees in particular. 

If there were a lot of interest in an AX1B, we would consider it. 

73,
Wayne

Re: [Elecraft] Change history in New Web Site

[Grant Youngman]

It’s on the firmware page, just not shown explicitly as a link (something that 
should probably be changed).

Go to the firmware page (e.g., for the K3S/K3) and under the heading “current 
Production Firmware Release Notes”, there’s a link in the second bullet “See 
firmware Release Notes”.  Your cursor will find it — at “Firmware Release Notes”

Re: [Elecraft] Elecraft CW Net Announcement

[Bill Frantz]

The time changes just after halloween. It was moved to that date 
fairly recently to try to protect the small children out on the 
streets trick or treating. (The big ones have always gone out 
after dark.)

Good Evening,

A sunny, warm week kept me busy outside.  Lots of colors but the
mild weather slowed the mushrooms.  The hunters keep driving by but
between the local clear cutting and the private land they're not finding
anything.  They need to stop following the roads along the ridges and
hike into the valleys.  Good cover with lots of elk and a few bear.

A solar wind is due but it's already behind schedule. Tomorrow is
the last weekend before the time change.  I normally keep the same local
time and change the UTC  schedule.  That change moves the 40 meter net
to after dark for all of us.  20 meters is also effected because some of
the country is already getting dark which changes propagation.  With the
solar minimum almost upon us it might be better to have both nets
earlier in the day.  Further thought is necessary.


Please join us tomorrow on:

14050 kHz at 2200z Sunday (3 PM PDT Sunday)
   7047 kHz at z Monday (5 PM PDT Sunday)

73,
Kevin. KD5ONS

Re: [Elecraft] K3 vs. KX3 with wsjt-x

[Brian Waterworth]

It is not disabled automatically in Data A mode.   I have looked and if I
don’t set it purposefully it will remain at the last setting per band.  I
have macros that I use to toggle between voice operation and digital
modes.  I set the mic bias and mic btn menu items accordingly.

Happy to proven wrong as I could then shorten my macros.  But I have
experimented and what I have written is based on my observations of the
menu settings.   Also, I found nothing in the KX3 operation manual to
indicate mic bias or btn are disabled on Data A mode.

Re: [Elecraft] TX_INH input (pin 7 on ACC) behavior

[Edward R Cole]

Brian,

Page 19  of K3 manual near bottom of second column tells what you 
need to know.  Using TX INH set to HI=inh you apply about 5v to keep 
radio inhibited from transmitting.  To active TX you take line 7 = LO 
(ground).  Elecraft shows how you can wire +12V thru a 2.2k to 10K 
resistor to provide 5v to pin 7 (6.6K probably will be fine to do 
this).  You need to ground pin 7 to enable RF OUT IN TX.


Or provide 5v to pin 7 thru a 1K resistor and ground pin 7 to 
TX.  The resistor limits current when the line is grounded;

See:  http://www.kl7uw.com/TX-INHIBIT.htm

pin 7 needs to be HI=5v or LO=grounded.  Leaving pin 7 unterminated 
(floating) will result in erratic operation.

Subject: [Elecraft] TX_INH input (pin 7 on ACC) behavior


With my early K3, I'm attempting to control the TX_INH line on the 
ACC Connector, and am finding this odd (to me) behavior.
Starting with the radio off, I'm driving the pin with either 0 or 5v 
through a 6.6K resistor per the Elecraft manual. I set the TX_INH 
mode to HI in the config screen, and even with the line NOT driven, 
TX_INH is indicated by the flashing TX in the display.
If I get out my Fluke VOM, I see that there's around 0.2v measured at 
pin 7... BUT THEN THE TX INHIBIT goes off (that is, it starts working 
as described in the manual)?? Is the TX_INH line floated in the radio?
?Do I need to also "pull down" this line to ground through a suitable 
high-value resistor?


Adding a 470K ohm to ground seems to make everything happy. If this 
is expected behavior (requiring pull down as well as pull up), 
perhaps this could be mentioned in the manual in the future (maybe it 
only matters to my era of K3 radio -- #512)


What makes this a little more difficult to debug is that after the 
line has been measured with the meter, causing it to work, TX_INH 
sometimes continues to work (High=inhibit, LO=tx). Until I power 
cycle the radio.

Anyone who has done this before have any insight?thanks,-Brian N9ADG

I think the mic bias is automatically disabled in DATA A mode. But I might be

 Not that on both radios other actions which use the CAT interface, like 
 changing bands from the wsjt-x UI, work correctly.
 
 The K3 has been upgraded to the internal sound card/RS232 interface from 
 the K3S.
 
 The KX3 is being used with a USB <--> RS232 cable and a home brew audio 
 interface using a mini-dongle USB sound "card".
 
 The computer in both cases is a MacBook Pro.
 
 Has anyone else experienced this issue?
