[Elecraft] Elecraft CW Net Report

[kevinr]

Good Evening,

   High haze came in.  Better contrast would be nice because a comet 
looks like a stream of smoke.  Last night I found Neowise under the Big 
Dipper but it was noticeably fainter than two days before.  It will be 
visible in binoculars for another few weeks.


   Conditions were poor to OK.  QRN on twenty meters and a persistent 
ESP signal on forty meters.  I think I was trying to copy the noise.  
The Midwest is hot and wet.  If you have a lawn of an acre or more you 
are continuously mowing it.  There are no breaks until the first frost.  
Plus you have very healthy mosquitoes.  They always make a difference.


   Roy reported the hottest temperature at 105 while Brian was still in 
the coastal clouds at 60 degrees.  It got to 85 here on the mountain.  
Even now it has not cooled very much.  The bugs want to invade here too.



  On 14050.5 kHz at 2200z:

K0DTJ - Brian - CA

K6XK - Roy - IA

NO8V - John - MI

K4TO - Dave - KY


  On 7047.5 kHz at z:

WM5F - Dwight - ID

K6PJV - Dale - CA

K0DTJ - Brian - CA


Until next week stay cool, get on the air, and 73,

 Kevin.  KD5ONS

Re: [Elecraft] KPA1500 with K4 tracks VFOs with 1 kHz resolution

[Wayne Burdick]

The K4 defaults to K3/K3S auxbus protocol, ensuring compatibility with a 
KPA500, KAT500, or KPA1500. 

It will only use the new protocol if the amp or tuner has been configured to 
use K4 mode.

Hi Andy,

The improved resolution ensures that the correct bin is detected when you get 
within +/- 1 kHz of the target ATU LC data bin rather than +/- 8 kHz. This 
improves repeatability of selected LC values vs. VFO frequency, especially on 
160 and 80 meters where it's most likely to matter.

This also means that, in the future, we could use smaller bin width on some 
bands if desired. This could be helpful if you were using the ATU to fine-tune 
a very narrowband antenna such as a loop or electrically short vertical.

[Elecraft] KX3-2M TO-220 Retainer and Nylon Screw

[AL7CR]

Does anyone know if these parts are a recent change?  My pal is sending me his 
board and it did not have these parts.  The heat sink was attached to the case 
directly with a metal screw and the nylon screw was not present and the hole 
for it empty.

If the parts are strictly required I will try and get them from the factory 
tomorrow.

Thanks for the help.

At this point in time, it may not matter. But who knows how we will be 
using our radios 10-15 years from now? The early K3s on my operating 
desk were built in 2007, and probably designed a year or two earlier. 
There are a few things about those radios I wish were a bit better. 
Great designers (and leaders) have the intellect and imagination to 
think WAY ahead of today, and plan for tomorrow.

Re: [Elecraft] KPA1500 with K4 tracks VFOs with 1 kHz resolution

[Andy Durbin]

"How does that help anything if the tuner bin width is 8 kHz? "

I had confused the rf frequency detect counter resolution with the bin width.

For KAT 500:

Below 3 MHz the segments are 10 kHz wide.
>From 3 MHz through 26 MHz the segments are 20 kHz wide.
>From 26 MHz to 38 MHz the segments are 100 kHz wide.
>From 38 MHz to 60 MHz the segments are 200 kHz wide.

For KPA1500:

160 Meters, 10 kHz Steps
80 Meters, 10 kHz Steps
60 Meters, 20 kHz Steps
40 Meters, 20 kHz Steps
30 Meters, 20 kHz Steps
20 Meters, 20 kHz Steps
17 Meters, 20 kHz Steps
15 Meters, 20 kHz Steps
12 Meters, 20 kHz Steps
10 Meters, 100 kHz Steps
6 Meters, 200 kHz Steps

Both data sets extracted from the user guides.  They seem to be similar but I 
have not checked every frequency range.

I still don't see the advantage of AUX bus giving the KPA1500 the TX frequency 
to 1 kHz resolution.   What am I missing?

That’s not at all what it means.  K4 interfaces via AUXBUS with KPA500 and 
KAT500 as a K3.

Re: [Elecraft] KPA1500 with K4 tracks VFOs with 1 kHz resolution

[AL7CR]

Can you please confirm this means, at present, that the K4 does NOT interface 
with the KPA 500 and KTA 500 via the Auxbus.  If so, that is a major 
disappointment.  I presume operation is still possible in the frequency sensing 
mode as it is with non Elecraft amps.  Just writing that last sentence makes me 
sad.  

I would have thought the K4 would have shipped with a K3 compatibility mode.  
Surely I am not the only one considering replacing my K3 with a K4 and 
expecting not to lose capability.  It is also a bit sad that, if I understand 
correctly, you only HOPE to add compatibility in the near future.  There must 
be more KPA/KTA 500 out there than KPA 1500 by a huge margin.

[Elecraft] K2 For Sale, #03965, $735

[webri...@nc.rr.com]

I have a very good K2 for sale.  It has been to visit Don Wilhelm W3FPR twice 
before he retired from working on K2 radios.  He upgraded the radio, gave it 
the latest versions, and made everything perfect.  He also built the I/O serial 
style usb cable adapter plug and cable that attaches to the back.  I bought a 
KUSB serial cable from Elecraft to use with the cable adapter plug.

I have been considering selling this for a year or so.  I use my KX2 and 
FTDX3000 D often, and hardly ever use the K2 anymore.  I would rather sell it 
to somebody else so they could use it, than let it continue to sit here not 
being used.
The serial number is 03965.

The radio has the following options installed.
KAF2 Audio Filter and Real-Time Clock
KSB2 SSB Adapter
KNB2 High Performance Noise Blanker
K160M 160M and 2nd RX Port
KIO2 RS-232 Interface and Aux I/0
KAT2 Automatic Antenna Tuner
The KBT2 battery option was installed.  I removed it for easier access when 
adding the other options, and it will be include though it is not installed.  
There is no KBT2 battery with he radio.
There is no mic.  The plug is wired for an Elecraft mic.
The manual is included.
I most recently swapped out the speaker and speaker cloth with new ones from 
Elecraft.
Price is $735 firm.  Shipping with insurance will be an additional $30.00

Payment will be a Postal Money Order or if in person, cash.

I will ship the radio after the Postal Money Order clears the bank.  
If you are serious, and would like pictures or video, please email me.

Thank you,
73, Steve - KI4EZL

Re: [Elecraft] K4 and RTTY question

[Bob Wilson, N6TV]

Bill,

Before it can be "fixed" in the K4, the logging software has to be fixed to
send the proper KY command.  If it is sending KY*somes-string*;,
then the messages are not going to be chained.  If it is sending KYW
*some-string*;, then the messages should be properly chained, perhaps with
a very brief pause in between if 0x04 (Ctrl-D, ^D or EOT -- ASCII End of
Transmission character) is appended at the very end of a each chained
message, before the terminating semicolon.  The "W" means "wait for message
completion," as documented in the K3 Programming Manual.

However, once a message sent via KYW starts, you will not be able to
interrupt the transmission by pressing "Escape" or sending an "RX;"
command.  The RX; won't be processed until the message completes, which
isn't very helpful.

Maybe *that* will be addressed (somehow) in the K4.

In sum, if you need chaining more than you need message interrupt
capability, use KYW in your macros.  If you need message interrupt
capability more than you need chaining, use KY.  If you need both,
maybe you'll have to "wait" (sorry) to see if the K4 team comes up with
some way to interrupt chained messages already in progress via a special
"high priority" software command or key tap.

73,
Bob, N6TV

[Elecraft] KPA1500 with K4 tracks VFOs with 1 kHz resolution

[Andy Durbin]

"Those using a K4 transceiver with our KPA1500 amp will have the advantage of 
+/- 1 kHz resolution in VFO tracking. "

How does that help anything if the tuner bin width is 8 kHz?  I could provide 
any frequency update resolution I wanted with my controller but I chose to 
limit it to 8 kHz to match the KAT500.   Doesn't the KPA1500 also have 8 kHz 
wide bins?

Will the frequency priority logic of the KPA1500 change?  Doesn't RF detected 
frequency with 8 kHz resolution, and some uncertainty in detected frequency, 
override any frequency provided by Aux bus or CAT?

If these limitations have been overcome for KPA1500 will the changes be rolled 
back into the KAT500?

Re: [Elecraft] Matching resonant antennas

[Al Lorona]

Using AC6LA's Line Loss calculator, and making the following assumptions:

Line impedance: 420 ohms,  (1/4" copper pipe spaced 4 inches apart)
SWR at antenna:  14.0  (Z = 30 ohms)
Line attenuation:  0.0266 dB/100 feet  (Duffy, "RF Two Wire Transmission Line 
Loss Calculator", owenduffy.net/calc/tl/twllc.htm)
Length of line:  500 feet  (conservative estimate that probably represents a 
worst-case?)
Frequency: 10 MHz

Total Line Loss = 0.891 dB

Re: [Elecraft] KX3 - Receive Opposite Sideband and I.F. Image Nulling question

[Grant Youngman]

I think there’s a problem with the instructions.  I could not hear a signal 
when the VFO was set 16 KHz above the KX3 frequency with RIT off as you say.  
But you will hear it with RIT turned on.

[Elecraft] KX3 - Receive Opposite Sideband and I.F. Image Nulling question

[Mike Parkes]

I am trying to perform only page 5 of the RX sideband null procedure, and
and have a question. (My KX3 is a later serial number 9852 and according to
the RX sideband null A8.doc, most of this nulling procedure was performed
when the KXFL3 was installed by Elecraft, the only part not done(?) is the
2nd part of the  RX SHFT=8.0 I.F. Image (16 kHz) Nulling procedure which is
on page 5 of the PDF document.)

So, I am trying to work through this (using an XG3 with its freqs set per
the instructions to  1810, 3510, 5310, 7010, 10110, 14010, 18110, 21010,
24910, 28010, 50010) and I am at Page 5, Step 7:

  7. Optimize RX SHFT=8.0 I.F. image gain and phase settings as follows: a.
Set both the signal source and KX3 to the target band (starting with 160
m). Recall that *the VFO should be set 16 kHz higher than the signal source*.
Make sure you’re in CW mode. (Note: You can change bands and modes from
within the RXSBNUL menu entry.) *You should hear a strong signal,* and see
an S-meter reading of between S9 and S9+30 dB. If not, adjust the preamp
setting or the RF source level.

What strong signal? With the KX3 iin CW mode, set to 16 KHz higher than the
signal generator frequency, there is no signal at all heard! If I tune down
on 160 meters to the XG3 freq at 1.810 KHz then it is very strong S9. What
am I doing wrong here?
Thanks for any help!

[Elecraft] KPA1500 with K4 tracks VFOs with 1 kHz resolution

[Wayne Burdick]

Those using a K4 transceiver with our KPA1500 amp will have the advantage of 
+/- 1 kHz resolution in VFO tracking. In many stations, this finer resolution 
will result in lower SWR and improved amplifier performance, especially on the 
lower bands. (The original resolution was +/- 8 kHz.)

This is part an overall upgrade of our Auxbus control interface, taking 
advantage of the additional processing resources available in the K4. The 
revised protocol allows for more robust RFI rejection, as well as future 
enhancements to amp/tuner control. 

At present only the KPA1500 supports radio type K4, but we hope to add this 
capability to the KPA500 and KAT500 in the near future.

All amps and tuners will continue to support the original Auxbus protocol, 
remaining 100% compatible with our existing transceivers.

73,
Wayne

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 :-)

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.

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

Re: [Elecraft] Cooling Fans

[Steef PA2A]

Tom,

a few weeks ago the PA temperature of my K3 #1184 jumped between 32 and 
41 degrees Celsius during receive, and the fans went on and off. The 
problem went away after dismantling the K3 completely for another 
problem and the fan/temp problem has vanished. Maybe some loose 
connector had caused the problem. Monitoring the PA temp can be the 
first step to solve the problem.

Hi,

FWIW.

Test conditions measured under the K3 DISP menu:

14.1V
1.38A Sub RX on
PA 32C
FP 40C

PA fans off
PA fans on/off at 36C/35C

Room temp 22C

K3 FP and PA temp sensors calibrated against a laboratory thermometer 
adjacent to the K3.


Never really noticed when the PA fans come on in idle conditions due to 
PC fan noise.

Re: [Elecraft] K3 Issue

[mike stokes]

I had the same issue and it was a bad connection on the TMP cables.  I just
reseated all of them and all has been OK for me.  I hope I didn't just jinx
it.

Re: [Elecraft] K3 Issue

[Victor Rosenthal 4X6GP]

I suggest that you call Elecraft Support on Monday. I'm sure they have a 
diagnostic procedure that they can take you through on the phone. Even 
if there IS a failure somewhere, chances are that you can fix it 
yourself with their help.


Just guessing, but I suggest you open it and make sure all the small 
coax cables to the synthesizers are well seated. Since it was recently 
shipped, something could have worked loose.

The is NO noise shown on the S meter and I have a pretty constant S3

Regardless of mode selected there is no power output, the display

When I activate the tuner, regardless of band, it shows no SWR, says
5 watts out, but there is NO POWER OUT of it. It always acts like it

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

I recommend a careful reading of the manual, perhaps in PDF form with

Re: [Elecraft] Matching resonant antennas

[Lyn Norstad]

Ken -

You are absolutely right, and I totally agree that there needs to be
something to compare to in order to evaluate performance in a meaningful
way.  My mistake was in assuming that my judgment, after 50 + years of doing
this, would be accepted without laying out all the details, especially when
combined with actual on-air performance (during times of less favorable
propagation).

So let me add to my prior post that I have spent a great deal of time with
different "simple wire antennas" including inverted-V, sloper, end-fed, G5RV
and yes ... several different "true" dipoles.  Some single band, some
resonant, some not, some with traps.  And a few verticals with traps, base
loading, center loading and top loading.  And one three element tri-bander
at about 55 feet.

I am basing my opinion of this current EDZ on my experiences with those.
That being said, I do not currently have any of those in place in order to
facilitate an actual A/B test under exact same conditions.  Nor do I plan to
go to the cost or trouble to do so in order to satisfy the 5% of me that
thinks it might be meaningful.

Lyn,

How do you measure your antenna's performance?

In many cases, not necessarily yours, antenna performance seems to be based
on countries worked, achieving WAS/DXCC, "It's way better than last year's
antenna.", or "I worked Pitcarin Island last week."  None of these
"measures" are meaningful.  I am a big proponent of having a half-wave
dipole as one's "standard" antenna then using the RBN, WSPRLite, etc. to
capture same-time data on the performance of each antenna over time.

In other words, to say one's antenna works, is meaningless.  To say it works
well is also meaningless.  To say it works better than...can have some value
and perhaps even meaning.

Interesting post. I thought this was the case with my K3 also, but i 
figured out later that it was the fan in my power supply instead. Poor
