[Elecraft] Elecraft CW Announcement

[kevinr]

Good Evening,

   Christmas day was white and it remained so for a few days.  Then ice 
and back to rain.  Today was surprisingly sunny and the moon is shining 
brightly.  The coyotes are making a lot of noise as the pack moves 
past.  They enjoy the break in the cold and wet but I think the moon is 
effecting them too.  It had been pretty silent during the cold, it is 
nice to have the birds and beasts back again.


   The sun has been spotless with flux slowing too.  Since the storms 
aren't creating much lightning the noise should be low. Maybe the quiet 
conditions will allow us to work the weakened signals.  We can test them 
tomorrow with our last nets of 2017.


Please join us tomorrow on:

   14050 kHz at 2300z Sunday (3 PM PST Sunday)
    7045 kHz at 0100z Monday (5 PM PST Sunday)

    73,
    Kevin. KD5ONS

Happy New Year!

Re: [Elecraft] 80 meters

[Brian Hunt]

I had a similar problem on the low bands. I did three things:  1- Replaced the 
stock power cord with ~4 ft of #10 twisted pair cable; 2- Turned up the no-load 
voltage on the Actron linear supply to 14.2 v which gives me better than 13.5v 
@ 100w key down on the K3 display and 3- reran the K3 Power Cal procedure with 
the K3 Utility. It's been fine ever since.  GL+HNY

Re: [Elecraft] 80 meters

[Barthold Lichtenbelt via Elecraft]

Make sure your power supply provides enough voltage and can handle the power 
draw (300 watts is probably a good number). This happened to me too when I 
accidentally adjusted the voltage of my PSU too low. I now have it at 13.6V.

Re: [Elecraft] KX2 CW tx decode for code practicing using external straight key

[Joan]

Fine business, Bjorn ^_^

One my fav ways to elmer the Morse code as practiced is, in fact, to set folx 
around a table and pass the ‘transmitting station’ around the table and have a 
real roundtable QSO (albeit only acoustically)

You can use your KX2 as the code practice oscillator by turning VOX off (or 
even just dialing the power down to 0.0, although the finals will still draw 
some power even at zero final output).  You could just set the rig in the 
middle and then pass the key around.  I’ve used this method for decades

tnx fer the chat  es c u dn the log = 73 all  de KX2CW Joan  sk  . .

PS: Left Hand is a brewery in Colorado (I believe), and their’s is my favourite 
American-brewed stout ^_^

[Elecraft] Y-BOX New Years Day Sale + Announcing New Version for KAT500 / KPA500 / KPA1500 / SteppIR Owners

[Bob Wilson, N6TV]

In honor of the New Year, all Y-BOX orders received before midnight Pacific
Time New Years Day (by 2018-01-02 08:00 UTC) will get $10 off each unit,
while supplies last.  This applies to the original model only, with all 15
pins of the K3 ACC connector wired in parallel to all five DE-15
connectors.  I only have about a dozen of these original units left, and
this will be the end of the production run.  However, a new version is
being developed (see below), and I'm starting a waiting list for that now.

(The Y-BOX is a 4-way passive splitter and breakout box for the 15-pin
Elecraft K3 and K3S ACC / AUX port.  See https://bit.ly/Y-BOX .)

The original Y-BOX requires a KPAK3AUX cable (P/N E850463) between the
Y-BOX and a KAT500, KPA500, or KPA1500.  This cable has one male and one
female (M/F) DE-15 connector, with no connection on five of the pins, as
required by the amp.  The original Elecraft cables were bulky monitor
cables that had five pins cut. That was much improved more recently.

The NEW Y-BOX will provide the same function as the Elecraft AUX cable.
ONE of the DE-15 connectors marked "AMP AUX" will have no connection on
those 5 pins.  This means you can use a stock $10 M/F DE-15 cable with all
15 lines wired (NOT a VGA cable) between the Y-BOX and a KAT500 or KPA500,
and you can also use the same cable between the KAT500 and the KPA500.  Of
course you may still use the $24.95 Elecraft AUX cables on any of the DE-15
connectors if you already have them.

*Attention SteppIR owners*:

The Elecraft manuals recommend using a "Key Line Interrupter" to open the
KEY OUT line in the AUX cable (pin 10).  Then the SteppIR SDA100 controller
with the Tuning relay option
,
or the N8LP SteppIR Tuning Relay  is
placed in between the K3's KEY OUT phono connector, and the KPA500 KEY IN
phono connector, opening the KEY line while the SteppIR is tuning, to
prevent high power from damaging the SteppIR.

The NEW Y-BOX will have a Key Line Interrupt jumper built-in, optionally
splitting the amp KEY line (pin 10 of the AUX cable) into two RCA
connectors labeled KEY IN and KEY OUT.  Then you can conveniently connect
your "normally closed" SteppIR Tuning Relay to those RCA jacks.  With this
arrangement, you just need ONE DE-15 cable between the Y-BOX and the KAT500
/ KPA500 / KPA1500, and ONE stereo phono cable from the tuning relay to the
Y-BOX.  You no longer need to connect RCA cables from K3 KEY OUT and AMP
KEY IN.

*Attention K3-REMOTE users (K3/0-Mini and K3/0*):

"But there's one more thing ..." -- Steve Jobs

The NEW Y-BOX with a $10 cable can do one more thing that the stock
Elecraft AUX cable cannot:  it provides an internal jumper connection to
the amplifier's Pin 8 (PWR ON), a pin which has no connection in the
Elecraft cable.  You can then use a simple K3 macro to power up the KPA500
or KPA1500 remotely.  No PC required, no relay required.   The macro is
described on Page 21 of the K3 Remote Owner's Manual
.
 It generates a pulse on DIGOUT1 (Pin 11) to power up the amp.  This will
not work with the stock Elecraft AUX cable, but works fine with a M/F DE-15
cable from the Y-BOX to the amp. if the internal jumper is connected.

To review, *order the original Y-BOX any time before midnight PT this
Monday* to receive the one-time $10 discount on each unit, while supplies
last, or indicate in the notes if you prefer to be put on the waiting list
for one of the *new* units with the dedicated connections for Elecraft
Remote, SteppIR, KAT500 / KPA500 / KPA1500.  M/F Amphenol DE-15 cables in
both 2.5 ft and 5 ft lengths are now available to order too, but these only
work with the new Y-BOX, or between KAT500 and KPA500.  Cables are not sold
separately unless you have previously purchased a Y-BOX from me.

https://goo.gl/forms/Guu6OC6NinTlasY93

Thanks for all your support of my little project over the last year, and
Happy New Year to all!

73,
Bob, N6TV

Re: [Elecraft] P3 showing sigs on Aux antenna in diversity mode?

[Dale Boresz]

Hello Bill,

It *seems* to me that the following would achieve your goal, but the
gazillion cables behind the radios at this wireless station discourages me
from attempting to pull the K3 out away from the wall far enough to
actually try it.

-- Disconnect your low-noise rx antenna from the K3 'AUX RF' input, and
connect it instead to the K3 RX ANT 'IN'.
-- Then, engage the "RX ANT" button on your K3. You will then be listening
to your low-noise rx antenna on the main receiver, and that is what will be
displayed on the P3.
-- Then, use a BNC-to-BNC jumper cable to connect the K3 RX ANT 'OUT' to
the K3 'AUX RF' input. That will let you listen to your noisy TX antenna on
the 2nd receiver, the output of which will not be displayed on the P3.

73,

Dale - WA8SRA

[Elecraft] P3 showing sigs on Aux antenna in diversity mode?

[Bill Conwell]

For 160, I've got a noisy TX antenna, and a quiet RX antenna.  I sometimes
run them in diversity mode, with TX antenna connected to K3's ANT1 port,
and RX antenna connected to AUX port.

Diversity works fine.

But the P3 shows the IF from the noisy TX antenna - in which many weak
stations are obscured by noise.

Is there any configuration by which I can get P3 to show, instead, the
signals from the quiet RX antenna (connected to AUX input)?

Tnx,

Agent in decoding unless your sending is
closer to perfect, but it does tell you the speed in wpm as it decodes

if you have trouble.  With this one, it's really important to put the

[Elecraft] KXPA100 160 ATU Issue

[Dave Sublette]

I'm helping my son, K4TOO do some antenna work.  The antenna is up and
tunes on all bands with the KX3 on QRP.  When we put the amp in line, the
amp ATU tunes all bands, except 160.  When we hit the ATU tune button on
160, there are no clicking sounds.  The SWR remains High and the power out
is low, I suppose because the SWR is high and the SWR protection is
shutting down the finals.

The Amp is a year old and has worked well until July.  It hasn't tuned 160
since then. What I am trying to say is I think it is a problem with the
amp, not the antenna.

I'm not sure how to proceed.  I'm away from all my tools, so I am somewhat
limited in troubleshooting options.

Anyone have any suggestions?  Thanks.

Dave, K4TO

Re: [Elecraft] KX2 CW tx decode for code practicing using external straight key

[Bjorn Pehrson]

Jim, Joan, Ray, Ron, Wayne,

Thanks a lot for broadening my perspectives on cw code practicing, 
including prompting me to learn some Tamarian language and find out what 
a Left Hand Milk Stout is.


I am currently somewhere between 13-15 wpm receiving but know little 
about what I sound like when transmitting, and I feel I should explore 
that a bit before going on the air.


I could try recording/playback but a more interactive way would be nice. 
And if there is a tool available, I might as well use it rather than 
reinventing the wheel.


However, Jim, I  cannot find an app called "Morse Code Agent" in the 
Google Play Store. Do you have a pointer? I have gone through some of 
the many Morse code apps in there but have not yet found anyone offering 
the functionality that you mention.


Anyway, I wish you all a Happy New Year 2018.

Bjorn/sa0bxi

[Elecraft] Cady Books

[Rich Arland]

I'm looking at picking up the Cady book on the KX2. Is there any difference 
(other than price) between the LULU PDF version and the hard copy version from 
Elecraft?
