Re: [Elecraft] K3 FIRMWARE UPDATE: MCU 1.87, DSP 1.69 (Finally!)

[Bob Cunnings]

Does the advice for setting up soundcard digital modes given here:

http://www.mail-archive.com/elecraft@mailman.qth.net/msg53656.html

become effective when using this new version? Specifically:

"If you try and trick the system and run with *zero* ALC bars in
PSK31, the ALC has to work hard to give you your requested power - or
maybe it will think there is insufficient signal to work with - and
your Tx S/N may suffer. So, *please* set it to 4 bars in soundcard
"digital" modes."

This sounds right given the description of the ALC changes.

Great stuff Wayne, thanks!
One point and a question.  Firstly, the RPT OFS menu entry is not in the
config menu, it is in the main one :-)

Secondly, what is the deviation set to in FM mode?  For example, I would
dearly love to use the rig on 2m for our local repeater via my XV-144
but in the UK, that means narrow deviation.  Could that be made
adjustable if needed?

Many thanks

Ian


*** NOTE ***  You must use the latest version of our firmware loader 
(K3 Utility rev 1.1.4.1) or else you won't be able to load all 
components of the upgrade. It's available on our K3 software page, 
along with release notes:


http://www.elecraft.com/K3/k3_software.htm

As usual, if you have any difficulty with the firmware upgrade, send 
email to [EMAIL PROTECTED] Both Lyle, KK7P (DSP firmware) and 
myself (MCU firmware) will be closely monitoring your results in case 
further tweaking is required.


I'd also like to thank all of our K3 customers for their patience. 
This firmware release was delayed several times due to testing, 
engineering staff vacations, etc. Our field testers have been pounding 
on interim releases for weeks (thanks, guys). I hope you'll find it 
worth the wait!

MCU 1.87 / DSP 1.69, 5-3-08

  This release includes improvements in all areas. Changes are 
categorized below.


  NEW FEATURES:

  * CW KEYING IN SSB MODES:  While in SSB modes, you can now send CW 
without
changing modes or using an offset. The other station will hear the 
signal at your CW pitch.
This is especially useful on VHF bands when SSB signals can’t be 
copied.
To enable this feature, go into CONFIG:CW WGHT and tap ‘1’ until 
you see SSB +CW.


  * FM MODE ADDED: Requires FM filter installed in slot FL1. Those not 
needing
FM mode can set CONFIG:FM MODE to OFF. To set up a repeater 
offset: Use the
CONFIG:RPT OFS menu entry, then hold ALT to select -/+/simplex 
(-/+ appear under
the FM mode icon). To set up tone encode: hold PITCH, then rotate 
VFO B to select
PL TONE or PL OFF, and rotate VFO A to select the desired CTCSS 
tone. (When
PL TONE is on, a letter ‘T’ will appear near the FM mode icon.) 
Repeater offsets and

PL tones are stored per-band/per-memory.

  * VARIABLE AMP KEYING DELAY: Added CONFIG:TX DLY menu entry, which
sets the time from KEY OUT jack (active low) to first RF in 1-ms 
steps, from 8 to 20 ms.
To minimize loss of QSK speed, use the shortest delay that works 
with your amp.

Most will work with the default (minimum) setting of 8 ms.

  * LINE OUT ALLOWS RX/TX AUDIO RECORDING: Normally, CONFIG:LIN OUT 
sets a
fixed-level, receive-only output for main/sub (L/R), compatible 
with digital modes. Tapping
'1' switches LIN OUT to =PHONES, where the line outputs match 
headphone audio,
audio level controlled by AF/SUB gain controls, and both RX and TX 
audio available.


  * SIMULTANEOUS USE OF MIC AND LINE IN:  If the MAIN:MIC+LIN menu 
entry is set to
ON, and MIC SEL = FP or RP, the present mic OR line in can be used 
for transmit audio.
NOTE: Setting MIC SEL to LINE overrides the MIC+LIN menu entry 
(its parameter
becomes "N-A").  When MIC+LIN is in effect, rotating the MIC 
control shows MIC GAIN.

The op has to set MIC SEL to LINE temporarily to set LINE IN gain.

  * S-METER ABSOLUTE MODE: Use the CONFIG:SMTR MD menu entry. Set to ABS
(absolute) to have S-meter stay constant with preamp/atten 
settings. Default is NOR (where
PRE/ATTN affect the S-meter). ABS mode requires recalibration 
(SMTR OF & SMTR SC).


  RECEIVE:

  * SSB RECEIVE PASSBAND EXTENDED AT LOW END (now 100 Hz; was 200 Hz).

  * AM RECEIVE WIDTH RANGE INCREASED:  The WIDTH control in AM mode 
now has
a range of 2.8 to 10.0 kHz. Wider settings provide outstanding 
fidelity for hi-fi speech
and other wide-band signals. This is the *IF* filter bandwidth -- 
the traditional way to show
bandwidth for AM, because the required IF bandwidth is twice the 
modulation bandwidth.
NORM selects an IF bandwidth of 6.0 kHz in this mode. WIDTH 
settings above 6.0 kHz
will not be useful unless you have an FM-bandwidth crystal filter 
installed (at FL1).


  * IF A 2.8 KHZ FILTER IS INSTALLED, SSB "NORM" BW is 2.8 kHz (was 
fixed at 2.7 kHz).


  * AUTO-SPOT (SPOT with CWT ON) now works with both very weak and 
very strong signals.


  * PSK AUTOTUNE ACCURACY improved. You may still need to use RIT 
(FINE steps) to
tune in signals for best built-in text decode. (Also see 
CW-to-DATA in the Owner’s Manual.)


  TRANSMIT:

  * TRANSVERTER POWER CONTROL: The value set in CONFIG:XVn PWR now 
correctly
sets a fixed power level on the associated transverter band 
(0-1.50 mW or 0-12W).


  * POWER ROLLBACK BASED ON REFLECTED POWER:  Power rollback begins at 
about
2.5:1 at 100 W (and of cour

For the last few weeks and with the APP discussion, I was concerned that 
the DISPLAY on my K2/100 was showing 10.44 volts in receive mode whereas 
the DVM on my power distribution panel was showing a good 13.1 volts.


I was just about ready to tear this complex 12V power distribution 
system designed to commercial communications facility standards apart 
when I noticed that the LEFT side of the display was indicating 12.4! 
YupI was reading the divider and the current (0.44 A) as if it was 
10.44 volts !

wspr is a very low power beconing mode ... see k1jt .. it is a
derivitive of wsjt ..
I wonder if it is conceiveable that the k3 could incoporate wspr
decoding in its firmware ...
I should not imaging becon transmitting would be a problem ..

rational .. wspr beacons may become very common given the growth curve
on the wspr database ...
it could conceivably provide real time all band propogation

[Elecraft] K2/100 and Paclink Setup

[Phil Kane]

I am attempting to set up my K2/100 to send Pactor messages with the 
Paclink program via a Pactor-capable TNC.  In using my other digital 
data program, MixW, for BPSK31, I set a COM port to communicate with the 
K2/100's I/O port and the program controls the PTT line in the K2 very 
nicely.


I have attempted to do this with the Pactor program with no success. 
The K2 does not go into Transmit mode when set for PTT, and it pulses 
almost uncontrollably when set for VOX.


Has anyone succeeded in interfacing these two, or is a different Pactor 
program indicated?


With thanks for constructive advice.

Re: [Elecraft] K3 FIRMWARE UPDATE: MCU 1.87, DSP 1.69 (Finally!)

[Craig]

The SSB transmit chain has  had a major rework. The
results are very impressive. 

1. The ALC is vastly improved. In fact you could say
that the K3's ALC is perfect because it does not
contribute any measurable levels of IMD to the SSB
signal.

2. The increase in IMD levels when  you turn on the
speech processor is  non existent.

3. Excessive IMD levels under  heavy dynamic voice
testing is almost non existent.

4. IMD levels as measured at 5, 10, 15 and 20khz are
very impressive under dynamic voice conditions. If we
use the  measured data as per SM5BSZ's results, you
could conclude that the K3 has one of the best levels
of IMD suppression under dynamic voice testing
conditions. 

5. Under all levels of voice conditions, mic gain  and
speech processing settings it is just about impossible
to make the K3 splatter.

I did not do any 2 tone IMD measurements because i
don't have much faith in 2 tone numbers as a reliable
indicator of IMD performance under voice conditions.

6. In short, the K3's SSB transmitter performance is
close to  being  PERFECT.. 

Equipment used: Bird Attenuators, Tektronix 2467B,
Crystal Notch, Agilent 8594E, AOR7030+, SDR-IQ and a
Anritsu ML422C level meter. All tests were done on 14
mhz SSB.

[Elecraft] K3--Keying suddenly stopped

[Robert Tellefsen]

I was working the 7th District QSO Party, and doing fairly well
at 5w on both cw and ssb.  Then, just after I logged my 103rd QSO,
the keying stopped.

Neither the paddles nor the computer coming through the key jack
will cause a signal to go out in cw mode.  Keying the paddles does
give cw sidetone and the red TX light over the headset jack lights in
time to the keying.  I've cycled through the TEST mode several times,
but to no effect.

Holding the XMIT/TUNE button does cause a carrier at normal power.
Using
either VOX or PTT on ssb generates a normal signal

Either something has suddenly quit on me, or I've accidentally bumped
some adjustment that now inhibits keying.  No smell of leaking magic
smoke, so I expect it is some adjustment that isn't obvious or
documented.
I've dug through the manual and both the MAIN and CONFIG menus, but
nothing obvious.  There is a TX INH menu selection, but it is in OFF
status,
as it was before the keying quit.

I've tried cycling the power, but no change there.  I'm stumped.
Has this happened to anyone else?  Any ideas or suggestions where I
might look for something that is inhibiting cw TX?

Thanks and 73

[Elecraft] Re: Perfect K3 Speaker

[wayne burdick]

Hi Bruce,

For communications bandwidths, a sturdy 4-ohm, 3 or 4" diameter mobile 
speaker (non-powered) does a great job. For a bit more fidelity and to 
take advantage of the K3's stereo speaker outputs, I use a pair of good 
quality bookshelf-style speakers (again, non-powered).


Right now I'm using Best Buy's "Insignia, 4-inch, 3-way surround 
speakers," which sound quite good, although they're 8 ohms rather than 
4 so the available per-channel peak power will be lower. They're about 
4"W x 8"H.


I had been using just a single speaker, but having two allows me to get 
L/R separation of the main and subreceivers, as well as take advantage 
of the K3's "AFX" simulated stereo mode.

[Elecraft] Elecraft CW Net Announcement

[Kevin Rock]

Good Evening,
   It was a wonderful day today in a string of them.  I am getting wood cut, 
split, and stacked.  In a few days I will cease being so stiff and just bask in 
the pleasant glow of my labors.  I'll also have a nice stack of wood for next 
winter.  I think I can safely say spring is here.  It has only snowed a little 
this week!  The flowers are going crazy and I saw my first hummingbird of the 
season.  I know where one feeder is but Pat put the other somewhere I have not 
found yet.  Pat?  
   Just took a break from 7QP to write this announcement.  Forty is getting 
fluttery for the locals but the AZ and GA folks are coming in nicely.  I'll 
drop to 80 m soon to see how that is working.  Not a real contesting effort 
just a little practice.  Karl taught me not to use the headphones and to keep 
moving.  I have not called CQ yet just searching and pouncing.  There are 
plenty of stations out there though.  I know there are a few other contests but 
I have only worked the 7QP folks so far.  Did not get back in the house in time 
to test 20 meters but it was weak this week for my cross country skeds.  One of 
these days the sunspot cycle will start upward again.  Currently it in is the 
longest low in quite a few cycles.

modem or a bluetooth device.  The KUSB will appear as
"usbserial" in the Port menu. Be sure you are
selecting  "usbserial" as your port.

The Filter Configuration is still under development
and not yet functional in the Mac and Linux versions.

[Elecraft] K3 Firmware Update for Mac OSX won't talk to K3 --?

[KM5Q]

System: Mac OSX 10.5.2.
I have the KUSB adapter cable.
I downloaded AND installed the appropriate Prolific driver for my OS,  
as instructed (PL2303 driver). Installation looked normal. I  
restarted, etc.




I have K3 Utility v. 1.1.4.1
K3 is turned on, connected to USB port.
Port -- after Refresh Port List, I hit Test Communications. It says  
"MCU boot loader is ready for MCU firmware load RS232 39400 bps."


Firmware --
I GOT the download of new files from Elecraft OK -- Utility shows MCU  
Available:  01.87, etc.


I hit Send All New Firmware to K3

This is as far as I can get:
20:50:09 New firmware is available for your K3
20:51:29 K3 boot loader is waiting for MCU firmware load.
20:51:44 K3 boot loader is waiting for MCU firmware load.

This is the same message I was getting BEFORE I installed the Prolific  
driver.

I don't think computer is talking to K3:
Crystal Filter Configuration shows all zeros

K3 Config still shows 1.78
I turned K3 off, then back on. No help. Am I supposed to do something  
at K3 other than turn it on?


Frustrated!

We've just completed the most extensive K3 firmware
update ever. The 
full list of changes is provided below.


*** NOTE ***  You must use the latest version of our
firmware loader 
(K3 Utility rev 1.1.4.1) or else you won't be able to
load all 
components of the upgrade. It's available on our K3
software page, 
along with release notes:


 http://www.elecraft.com/K3/k3_software.htm

As usual, if you have any difficulty with the firmware
upgrade, send 
email to [EMAIL PROTECTED] Both Lyle, KK7P (DSP
firmware) and 
myself (MCU firmware) will be closely monitoring your
results in case 
further tweaking is required.


I'd also like to thank all of our K3 customers for
their patience. This 
firmware release was delayed several times due to testing,
engineering 
staff vacations, etc. Our field testers have been pounding
on interim 
releases for weeks (thanks, guys). I hope you'll find
it worth the 
wait!

Wayne, N6KR

* * *

MCU 1.87 / DSP 1.69, 5-3-08

   This release includes improvements in all areas. Changes
are 
categorized below.


   NEW FEATURES:

   * CW KEYING IN SSB MODES:  While in SSB modes, you can
now send CW 
without

 changing modes or using an offset. The other station
will hear the 
signal at your CW pitch.

 This is especially useful on VHF bands when SSB
signals can’t be 
copied.

 To enable this feature, go into CONFIG:CW WGHT and tap
‘1’ until 
you see SSB +CW.


   * FM MODE ADDED: Requires FM filter installed in slot
FL1. Those not 
needing

 FM mode can set CONFIG:FM MODE to OFF. To set up a
repeater offset: 
Use the

 CONFIG:RPT OFS menu entry, then hold ALT to select
-/+/simplex (-/+ 
appear under

 the FM mode icon). To set up tone encode: hold PITCH,
then rotate 
VFO B to select

 PL TONE or PL OFF, and rotate VFO A to select the
desired CTCSS 
tone. (When

 PL TONE is on, a letter ‘T’ will appear near the
FM mode icon.) 
Repeater offsets and

 PL tones are stored per-band/per-memory.

   * VARIABLE AMP KEYING DELAY: Added CONFIG:TX DLY menu
entry, which
 sets the time from KEY OUT jack (active low) to first
RF in 1-ms 
steps, from 8 to 20 ms.

 To minimize loss of QSK speed, use the shortest delay
that works 
with your amp.

 Most will work with the default (minimum) setting of 8
ms.

   * LINE OUT ALLOWS RX/TX AUDIO RECORDING: Normally,
CONFIG:LIN OUT 
sets a

 fixed-level, receive-only output for main/sub (L/R),
compatible 
with digital modes. Tapping

 '1' switches LIN OUT to =PHONES, where the
line outputs match 
headphone audio,

 audio level controlled by AF/SUB gain controls, and
both RX and TX 
audio available.


   * SIMULTANEOUS USE OF MIC AND LINE IN:  If the
MAIN:MIC+LIN menu 
entry is set to

 ON, and MIC SEL = FP or RP, the present mic OR line in
can be used 
for transmit audio.

 NOTE: Setting MIC SEL to LINE overrides the MIC+LIN
menu entry (its 
parameter

 becomes "N-A").  When MIC+LIN is in effect,
rotating the MIC 
control shows MIC GAIN.

 The op has to set MIC SEL to LINE temporarily to set
LINE IN gain.

   * S-METER ABSOLUTE MODE: Use the CONFIG:SMTR MD menu
entry. Set to ABS
 (absolute) to have S-meter stay constant with
preamp/atten 
settings. Default is NOR (where

 PRE/ATTN affect the S-meter). ABS mode requires
recalibration (SMTR 
OF & SMTR SC).


   RECEIVE:

   * SSB RECEIVE PASSBAND EXTENDED AT LOW END (now 100 Hz;
was 200 Hz).

   * AM RECEIVE WIDTH RANGE INCREASED:  The WIDTH control
in AM mode now 
has

 a range of 2.8 to 10.0 kHz. Wider settings provide
outstanding 
fidelity for hi-fi speech

 and other wide-band signals. This is the *IF* filter
bandwidth -- 
the traditional way to show

 bandwidth for AM, because the required IF bandwidth is
twice the 
modulation bandwidth.

 NORM selects an IF bandwidth of 6.0 kHz in this mode.
WIDTH 
settings above 6.0 kHz

 will not be useful unless you have an FM-bandwidth
crystal filter 
installed (at FL1).


   * IF A 2.8 KHZ FILTER IS INSTALLED, SSB "NORM"
BW is 2.8 kHz (was 
fixed at 2.7 kHz).


   * AUTO-SPOT (SPOT with CWT ON) now works with both very
weak and very 
strong signals.


   * PSK AUTOTUNE ACCURACY improved. You may still need to
use RIT (FINE 
steps) to

 tune in signals for best built-in text decode. (Also
see CW-to-DATA 
in the Owner’s Manual.)


   TRANSMIT:

   * TRANSVERTER POWER CONTROL: The value set in CONFIG:XVn
PWR now 
correctly

 sets a fixed power level on the associated transverter
band (0-1.50 
mW or 0-12W).


   * POWER ROLLBACK BASED ON REFLECTED POWER:  Power
rollback begins at

Re: [Elecraft] Perfect K3 Speaker

[Don Wilhelm]

Bruce,

The K3 offers 'stereo' with the subreceiver, and the AFX effects when 
selected (without the subreceiver too).  So I think the best external 
speakers are moderate to good quality computer stereo speakers.  I 
bought a pair for about $25 at Staples and they serve me adequately.


For mono only external speakers, the Motorola communications speakers 
are a good choice.

Re: [Elecraft] from John K3JK

[Don Wilhelm]

John,

I seriously doubt that plugging a mono plug in the K2 key jack would 
cause any damage - although the K2 would do strange things while the 
mono plug was inserted.


To check it out, plug a bare (no wires attached) stereo plug into the 
key jack.  If you then get a constant carrier, look for a problem with 
the K2, but if the K2 behaves normally (no keying), look for a problem 
between your external keyer and the K2 - I would start by checking the 
wiring for your new stereo plug.


73,
Don W3FPR

keyed the rig once.  Could I have blown shorted something in the keying circuit?

  NEW FEATURES:

  * CW KEYING IN SSB MODES:  While in SSB modes, you can now send CW
without

signal at your CW pitch.
This is especially useful on VHF bands when SSB signals can’t be

MCU 1.87 / DSP 1.69, 5-3-08

  This release includes improvements in all areas. Changes are
categorized below.

  NEW FEATURES:

  * CW KEYING IN SSB MODES:  While in SSB modes, you can now send CW
without
changing modes or using an offset. The other station will hear the
signal at your CW pitch.
This is especially useful on VHF bands when SSB signals can’t be
copied.
To enable this feature, go into CONFIG:CW WGHT and tap ‘1’ until
you see SSB +CW.

  * FM MODE ADDED: Requires FM filter installed in slot FL1. Those not
needing
FM mode can set CONFIG:FM MODE to OFF. To set up a repeater
offset: Use the
CONFIG:RPT OFS menu entry, then hold ALT to select -/+/simplex
(-/+ appear under
the FM mode icon). To set up tone encode: hold PITCH, then rotate
VFO B to select
PL TONE or PL OFF, and rotate VFO A to select the desired CTCSS
tone. (When
PL TONE is on, a letter ‘T’ will appear near the FM mode icon.)
Repeater offsets and
PL tones are stored per-band/per-memory.

  * VARIABLE AMP KEYING DELAY: Added CONFIG:TX DLY menu entry, which
sets the time from KEY OUT jack (active low) to first RF in 1-ms
steps, from 8 to 20 ms.
To minimize loss of QSK speed, use the shortest delay that works
with your amp.
Most will work with the default (minimum) setting of 8 ms.

  * LINE OUT ALLOWS RX/TX AUDIO RECORDING: Normally, CONFIG:LIN OUT
sets a
fixed-level, receive-only output for main/sub (L/R), compatible
with digital modes. Tapping
'1' switches LIN OUT to =PHONES, where the line outputs match
headphone audio,
audio level controlled by AF/SUB gain controls, and both RX and TX
audio available.

  * SIMULTANEOUS USE OF MIC AND LINE IN:  If the MAIN:MIC+LIN menu
entry is set to
ON, and MIC SEL = FP or RP, the present mic OR line in can be used
for transmit audio.
NOTE: Setting MIC SEL to LINE overrides the MIC+LIN menu entry
(its parameter
becomes "N-A").  When MIC+LIN is in effect, rotating the MIC
control shows MIC GAIN.
The op has to set MIC SEL to LINE temporarily to set LINE IN gain.

  * S-METER ABSOLUTE MODE: Use the CONFIG:SMTR MD menu entry. Set to
ABS (absolute) to have S-meter stay constant with preamp/atten
settings. Default is NOR (where
PRE/ATTN affect the S-meter). ABS mode requires recalibration
(SMTR OF & SMTR SC).

  RECEIVE:

  * SSB RECEIVE PASSBAND EXTENDED AT LOW END (now 100 Hz; was 200 Hz).

  * AM RECEIVE WIDTH RANGE INCREASED:  The WIDTH control in AM mode
now has
a range of 2.8 to 10.0 kHz. Wider settings provide outstanding
fidelity for hi-fi speech
and other wide-band signals. This is the *IF* filter bandwidth --
the traditional way to show
bandwidth for AM, because the required IF bandwidth is twice the
modulation bandwidth.
NORM selects an IF bandwidth of 6.0 kHz in this mode. WIDTH
settings above 6.0 kHz
will not be useful unless you have an FM-bandwidth crystal filter
installed (at FL1).

  * IF A 2.8 KHZ FILTER IS INSTALLED, SSB "NORM" BW is 2.8 kHz (was
fixed at 2.7 kHz).

  * AUTO-SPOT (SPOT with CWT ON) now works with both very weak and
very strong signals.

  * PSK AUTOTUNE ACCURACY improved. You may still need to use RIT
(FINE steps) to
tune in signals for best built-in text decode. (Also see
CW-to-DATA in the Owner’s Manual.)

  TRANSMIT:

  * TRANSVERTER POWER CONTROL: The value set in CONFIG:XVn PWR now
correctly
sets a fixed power level on the associated transverter band
(0-1.50 mW or 0-12W).

  * POWER ROLLBACK BASED ON REFLECTED POWER:  Power rollback begins at
about
2.5:1 at 100 W (and of course much higher SWRs are tolerated at
lower power settings).
Recovers to original target power level after mismatch is
corrected.
  * CW QSK further refined, with smoother mute/unmute in the presence
of QRN and QRM.

  * SSB TRANSMIT BANDPASS EXTENDED A

[Elecraft] from John K3JK

[John Klokis]

John K3JK here, Would someone give me some feedback on my K2?   I plugged a 
mono plug into my keyer jack when I was using an external keyer.  I might have 
shorted a resistor or diode.  now as soon as i plug the keyer in with a stereo 
plug, i get a constant carrier.  When I had the mono plug in the keyer jack, i 
keyed the rig once.  Could I have blown shorted something in the keying circuit?

Start them with a Heathkit nut starter! It's a little plastic tube  
just soft enough to stretch over the two main sizes of nuts. Makes it  
SO much easier to start those little buggers.

You'll need to find an Old Master who saved them from the good old  
days. Get on his good side, and MAYBE he'll give you a nut starter he  
saved from the good old days.

Then, promise to save it for the next generation.

Chris,

Yes, use TUNE - set the power level to somewhere between 1.5 and 2 watts 
and adjust for peak output.  Be certain to follow the band order 
indicated.  The bands are arranged in pairs, and the inductors for that 
pair must be adjusted before the capacitors.

The second column on page 80 starts stepping through the bands after

conjunction with the procedure like the tx adjustment for 40m done

[Elecraft] K2 data port integration rev. 2.0

[J-F VA2SS]

Hi,

I updated my data port schematic integration. I made several changes.

Here a few

* power external device from K2 12VDC AUX instead of own power source to
avoid ground loops
* remove audio transfo... not needed anymore... save space and less wires
* add the ALC mod on the SSB board... a must for all, espacially for digital
mode !!!

Schematic can be found at :

Re: [Elecraft] K2/KPA100 40M SSB ALC Problem?

[J-F VA2SS]

Thanks to Don Wilhem again ,and again !!! Youuhou !!

I got this behavior when testing my DATA port on my K2 trying PSK31 and
Pactor-2. The power output on 40m and 20m was way off between the two bands
using the digital mode. BUT, with this mod, it solved all my problems !!!

First of all, I think this mod should apply to all of you doing or not
digital mode with their K2.

AND.. I really hope I will meet Don Wilhem face to face one time in my
life to shake hands and telling him « Don, really thanks to you for all
your contributions to this discussion group  »

BTW, I will be at Dayton this year, just in case... my first time. :-)

J-F VA2SS (formerly VA2VYZ)



The conditions you describe are almost identical to the behavior 
experienced when the KI6WX SSB Increased RF Gain mod is added to the 
KSB2 board, *and* the KPA100 is also in-line.  The result of that 
combination is that there is more overall RF gain than the KSB2 ALC 
circuits can handle.  Your K2/100 may have a bit more available RF gain 
on 40 meters than the average K2.

The fix for the above is to change the KSB2 board ALC.  1) Cut the trace 
on the top of the board between P1 pin 6 and the base of Q1.  2) Install 
a 1k resistor over the previous cut (between P1 pin 6 and the base of 
Q1).  3) Change the value of R9 to 1.5k.  These changes were first 
suggested by Gary Surrency of Elecraft support.

You gentlemen may wish to try this even if you do not have the KI6WX mod 
installed.  I do not believe it will cause any other difficulties.

It is a mystery to me why the situation is not present with the display 
in ALC mode, but then I am not familiar with all the internal workings 
of the KSB2 firmware.  My guess is that the slight additional load 
provided when monitoring the ALC level is sufficient to control the 
overdrive.

73,
Don W3FPR

frequently used on the SSB frequencies when signals become too weak for voice

the other guy will hear it more or less centered in his SSB receive passband. 
No retuning. When you stop sending (or in between code elements, if you are

This feature was my favorite thing about the FT-897, which otherwise was a 
rather forgettable entry-level rig in terms of its close-in strong signal 
performance. Once again, the K3 is evolving into a stellar radio for both the 
HF and VHF/UHF worlds, where high-end performance requirements are really very 
different.

Re: [Elecraft] K3 VFO A tuning knob set screw

[John H Gibson]

Earlier I wrote:

I currently am assembling my new K3 #820 and have reached the step where I 
need to mount the VFO A tuning knob. I am unable to advance the knob's set 
screw far enough to clamp the knob to the shaft and am considering running a 
tap in and out of the hole to clean up the thread.

Does anyone know the diameter and thread pitch of this set screw? If I hold the 
screw against an 8-32 tap, it seems to fit, but I am worried that it might be a 
metric thread instead.
---
I now can report that I took the bull by the horns and used my 8-32 tap to 
clean up the set-screw threads in the VFO A knob. The 8-32 set screw then 
went in smoothly, and the VFO A knob now is mounted on the VFO A shaft 
encoder.

I ran intro a different problem with the VFO knob. The knob would not fit on 
the 
shaft, and I also could not insert a 1/4" drill bit shank into the knob. I then 
used 
a 1/4" drill bit to gently ream out  the knob, and it now is mounted on the VFO 
B 
shaft encoder.

Thanks to Thomas, Vic, and Windy who were kind enough to respond to my 
request for help.

RE: [Elecraft] K3 VFO A tuning knob set screw

[Windy Dankoff KM5Q]

John,

If the threads of your tap mesh the screw, then the screw is NOT metric.
Metric size is noticeably different. If your tap's diameter also matches,
I'd go for it.

There is an identical set screw in the VFO B knob. Either set screw will thread 
easily into the VFO B knob, but either set screw will go just so far and then bind 
in the VFO A knob.


Just get a long screw that you know to be 8-32 and run it into the hole 
in the knob. If it goes easily (at least up to where the thread ends) 
then it is probably 8-32.

Re: [Elecraft] K3 - Linking the VFOs for CW - SSB switching

Ken and All,

I haven't followed this thread very closely, so now I'm a bit confused about 
the subject line.  If I understand it right, the question is can the K3 be 
set up so that you can just hit the paddle and be on CW, even though you 
have currently selected SSB.  Is that right?  If so, I'm not sure why the 
thread subject line says "Linking the VFO's...".  I would think it would 
just be a matter of automatically changing the mode temporarily for 
transmit.


I would assume that  Elecraft can do this, and if they do, the offset will 
be whatever you set it for.  Your CW sidetone is fully adjustable, and that 
would be the process.  My FT-897 (I assume the FT-857 has it too) has this 
feature, and it is pretty handy at times.  Via the menu you can set this 
feature to be active (menu #22), and you can even choose whether the offset 
is up, down, or automatically selected for you (menu #23).  But the amount 
of the offset is based on whatever you have set previously for CW operation, 
which is what you would want.  You can be talking on SSB, then just hit the

Re: [Elecraft] K2: Hi Cur problem solved

[Don Wilhelm]

Daniel,

It is not common to find a bad capacitor, but indeed it does happen.
In situations where something like that is expected, I usually do a 
sweep of the LPF to reveal the approximate filter cutoff frequency.   A 
bad component in the LPF will show up readily using that technique (but 
you still have to figure out which component, usually by trial and error).


It is possible to sweep the K2 LPF with an antenna analyzer connected to 
the BNC jack, but you must isolate the input of the LPF and connect a 51 
ohm resistor (easy to do if the K160RX is installed, but requires 
removing the W1 jumper if it is not.


73,
Don W3FPR.

Daniel Schlieper wrote:

Hi,

my K2 (#4271) had a HI CUR problem. While all other bands were fine, I

I checked and rewound the coils of the low pass filter (L16, L17) and 
touched up the solder joints of the capacitors C190, C191, C192. No joy.


But the problem was cured when the capacitors were replaced with new 
ones. How frequent is is to come across broken capacitors?

[Elecraft] K3 and contest logging programs

[hank k8dd]

Has anyone tried using Writelog or N1MM with the K3 on SSB using the 
program as a voice keyer, feeding the Line In jack in the back?
Did it work? If it did, how did you do it?
It appears to me that you have to switch MIC SEL from front or rear panel 
mic input to Line In.

[Elecraft] OT: K3 in a Pelican Case

[Dave Van Wallaghen]

For anyone interested, I wanted to take my K3 #338 with me on vacation in
northwest Alabama after Dayton this year. I wound up purchasing a new
Pelican case #1610 to house it for carrying it around for portable
operation. I'll admit the case is pretty expensive for something used
occasionally, but I've had nice success in the past with these cases, so for
me, it was worth it.

Here is a link to my website with pics:

[Elecraft] K2: Hi Cur problem solved

[Daniel Schlieper]

Hi,

my K2 (#4271) had a HI CUR problem. While all other bands were fine, I got 
a HI CUR error message on 80m, and output was down to 5 W.


I checked and rewound the coils of the low pass filter (L16, L17) and 
touched up the solder joints of the capacitors C190, C191, C192. No 
joy.


But the problem was cured when the capacitors were replaced with 
new ones. How frequent is is to come across broken capacitors?

[Elecraft] OT: FS: Tektronix 7854 Oscilloscope System (mainframe, plug-ins, manuals, cart)

[Howard Ashcraft]

I am trying to regain shop space and will be selling my very nice Tek 7854 
Mainframe Oscilloscope with a complete set of plug-ins. The mainframe was 
calibrated a couple of years ago by a lab in Silicon Valley and the 7B92A, 7A26 
and 7A24 plug-ins were calibrated within a few years, too.  Although they are 
not "current", this is not one of the cases where the last calibration was 20 
years ago  Before I advertise on eBay, I thought I would post it here in 
case someone is interested in this type of unit.  I am actually quite 
conflicted about selling this, because it is a wonderful scope, but since I 
have 3 1/2 scopes already...

If you aren't acquainted with the 7854, it is a 400 Mhz Bandwidth analog 
mainframe with digital storage and wave processing capabilities and is probably 
the Queen of the 7000 family of lab scopes. It is programmable from an attached 
keyboard and can perform a wide variety of waveform measurements (frequency, 
period, energy, etc.) and analysis on the digitally stored signal.  This 
mainframe has the 2D extended memory option.  It is in very nice physical and 
electrical condition.  The display is sharp (better than my 2465b) with no 
burn-in.  I have original Tek users and service manuals for this unit and for 
the 7A26 plug-ins.

The plug ins that I am including are:

(2) 7A26 2 channel, 200 Mhz, 1Mohm impedance
(2) 7A24 2 channel, 400 Mhz, 50 ohm impedance
(1) 7A29 1 channel, 1 Ghz, 50 ohm impedance with Option 4
(1) 7A19 1 channel, 600 Mhz, 50 ohm impedance with Option 4
(1) 7A13 150 Mhz Differential Comparator
(2) 7B92A 500Mhz  Dual Delaying Time Base
(1) 7B87 Timebase with preacquisition  (this is the only 7000 series, and one 
of the few analog scopes that can look at events BEFORE the trigger.

(Note, the bandwidth of the oscilloscope system is limited by the 7854 
bandwidth, i.e., 400Mhz, although some of the plugins are rated higher.


7854 Service Manual Original in excellent condition
7854 User ManualOriginal in fair condition
7A26 Instruction Manual   (Has schematics and service information) Original in 
excellent condition
7A24 Instruction Manual(Has schematics and service information) Original in 
excellent condition
7B92A Manual, .pdf copy

Model 3 Scope cart in good condition.

This is only for pick-up in Alameda, CA as I do not want to ship this scope.  

I spent a lot of time and effort accumulating and vetting the bits and pieces 
and do not want to sell it except as a complete unit.  Price for everything, 
$850. If you need probes, I have a pair of virtually unused 250 Mhz Tek probes 
P6109a in original plastic cases with standard accessories for $45 a piece.

[Elecraft] K3 VFO A tuning knob set screw

[John H Gibson]

I currently am assembling my new K3 #820 and have reached the step where I 
need to mount the VFO A tuning knob. I am unable to advance the knob's set 
screw far enough to clamp the knob to the shaft and am considering running a 
tap 
in and out of the hole to clean up the thread.

Does anyone know the diameter and thread pitch of this set screw? If I hold the 
screw against an 8-32 tap, it seems to fit, but I am worried that it might be a 
metric thread instead.

Tnx Doug!

So it's a non-volatile *analog* memory! That's what wasn't clear in the
short article.  

Finally a memory that can store Morse from a hand fist. Maybe in a future

Now all we need to do is to figure out how to put that in breakfast cereal

[Elecraft] K2 Mic Gain parameter SSB vs Digital mode

[J-F VA2SS]

Hi,

Is there a way to modify the K2 that have 2 different parameters for mic
gain when using SSB or digital mode (RTTY ON) !?!!?

I know that we are able to set different parameter for compression if used
in SSB or RTTY mode... but for mic gain it is not possible. It would be
more useful to have different mic gain setting than compression !?!?!? We
never use compression in digital mode anyway !?!?!? I'm wrong ?!?

Thanks.

[Elecraft] KDSP2 center frequency increment value

[J-F VA2SS]

Is it possible to have the KDSP2 filters, by example for CW mode, to have the
center frequency increment by 25 Hz or less instead of 50 Hz. I see possible
optimization on my spectrum analyzer if I could have at least 25 Hz
increment. OK it would be around 1 dBV or less, but a lower increment
value could be more precise when aligning everything. And when using a 100
Hz DSP filter width... 50 Hz increment is too high. The DSP filters are very
effective compared to the crystal filters when used on narrow width like 100
Hz

Fred,
The front panel ground patch has fixed all of the problems associated 
with using biased element microphones that I am aware of.  The 
original three K3s affected were SN 690, 728 and 729.  Since then 
several others have complained about the same problems, although I 
haven't heard if the patch worked for them.  
The symptoms on my K3 were exactly the same as on yours when I used 
the Elecraft Proset.  Additional problems surfaced when using the 
Elecraft MH2 hand mike.  All of these abnormalities vanished when I 
grounded (with one small wire) the two capacitors that have the 
missing ground trace on the front panel board.  These are bypass 
capacitors by the way, not blocking.  An official field repair notice 
is expected soon from Elecraft.

[Elecraft] Re: 80 M (and more) on KX-1

[Albers]

When I travel with my KX-1 I have an antenna that works quite well on all 4 
bands.

I bought a 50 ft roll of speaker wire (a.k.a. zip cord) from Radio Shack - it 
turned out to be 51 1/2 ft long, but I don't think the length is very critical. 
I un-zipped all but about a foot of the wire, and I use one leg as a 
counterpoise, lying on the ground or sometimes hanging out a hotel room window 
and then draped along the ground. The other leg, I get as high in the air as I 
can. Depending on where I am, sometimes it's a sloper going up to a tree, 
sometimes it's a reverse sloper going from a 3rd floor hotel room window to a 
bush in the parking lot, sometimes it's sort of an inverted L, etc. Most 
recently in a campground in Chaco Canyon, NM it was an inverted U going over a 
big boulder near my tent. The KX-1 ATU loads it to an indicated 1.3:1 SWR or 
better on all 4 bands, and I've made lots of contacts with it.

RE: [Elecraft] Firmware uploads

[Dick Dievendorff]

I tried to address this with the K3 Utility Help text for the Firmware page:

DSP2

The sub receiver's Digital Signal Processor, present only if the KRX3 Second
Receiver Option is installed and enabled through the K3 CONFIG menu.

Installed in K3

Indicates the firmware versions installed in the K3 for each of these
processors. N/A indicates that the hardware option is not installed or has
not been enabled through the K3 CONFIG menu.

In this case, the KRX3 second receiver option has not been enabled in your
K3.  The related firmware file is "available" in that it's in the firmware
folder on your PC.  But your K3 has no second receiver to receive the file.

The "Send all new firmware to K3" button is disabled because MCU and DSP1
have the "available" version already installed, and there are no processors
in the K3 that have back-level firmware (comparing what's installed versus
what's available in the PC's firmware folder).

When your KRX3 is installed and enabled (via a CONFIG menu option), the K3
Utility will load the corresponding DSP file.  I have the DSP board part of
the KRX3 installed in my K3 for testing (I don't have the rest of the 2nd
receiver) and the K3 Utility is able to load that DSP2.  The firmware
authors that have the rest of the 2nd receiver have loaded their DSP2 many,
many times.

A blob of Coax Seal at the end of a shaft (dowel, screwdriver, pen
casing, etc.) will also do the job.

Re: [Elecraft] 80M on KX1

[Paul Huff]

Hi Tom,

I assume that you are talking about an easily deployable field antenna.  For 
convenience it's hard to beat a simple length of wire with a few radials on 
the ground.  I don't have 80-meters on my KX1 but I use a 42-ft wire for 40, 
30, and 20.  Of course that length won't help you, but here's the idea... 
Sometimes, because of the specific setup situation (angle of the antenna, a 
dog-leg in the wire, nearby structures, etc.) I am not able to get a good 
match with the ATU on all of the bands.  So I used some hookup wire to wind 
a coil on a plastic film canister and made taps about every-other turn.  If 
the ATU can't find a good match by itself I add in my coil between the rig 
and the antenna wire.  It doesn't take very long to find a tap that keeps 
the rig happy.  Something similar with a longer piece of wire might work for 
you.


Good luck and 73,
Paul - N8XMS

Can anyone tell me what length of end-fed line works best on 80M using a 
KX1
with ATU? I'm having a heck of a time trying to find a length that will 
work

with 80M and 40, 30 and 20. I know the ATU is not really designed to tune
80M effectively. It would be nice to have one antenna to do all bands, but
if not a separate wire for 80M is okay too.

Heh, heh getting a little itchy? Me too. I ordered at the end of
Dec. Anyway, here is the only December order I've seen reported here.
It was posted on May 1st:

I would certain find the feature an advantage when I use my K2 with my

Re: [Elecraft] KAT3

[Blachura]

Hi Gary,
I just used my KX1 on a mini trip. Used a endfedz dipole for 80/40/20.
Worked great with the kx1. Used a small coax from the rig and ran the dipole
up into a low tree using my shoe as a weight to get it up there HI HI. (got
the shoe back ). the dipole is about 80ft long. and I had a very low swr
with the rig.
You can check it out on web.

My comment about the K2 referred to the use of the mode switch (on the 
K2 PTT and one of the key lines are physically the same, so a mode 
switch is essential).  Where PTT and key lines are distinct, I would 
still see it beneficial to implement with the mode switch, even if it 
was also implemented as a, transmit only, feature with the key.


Unfortunately, K2 firmware changes are much more costly, although it 
might be worth stocking up on blank parts, in case the source is ever 
opened.

[Elecraft] KAT3

[Gary Gregory]

I have been carefully reading the instructions on the configuration and use
of the KAT3 and I am a little puzzled by what I have found.

I was surprised to find that the KAT3 does not track the VFO on receive. I
wonder if there is a reason for this?

Has there been any thought on perhaps an upgrade of the KAT3 in the future?

I have mono band antennas but the band edges are sometimes a little higher
than say the band centre and CW portions. Tracking on receive is something I
have become used to with previous radios.

Still learning how this radio works, all reports so far have been
exceptionally good. i just had a QSO with a station who asked me if I would
like to swap it for his SteppIR beam and an FT1000...been there, done that,
the K3 stays.

Cheers all,
Gary

The expression "end fed line" makes me confused as to what you are 
actually talking about.  The other replies have ignored the "end fed" 
and read the "line" as "transmission line" (transmission lines in 
amateur radio are generally always end fed (although that's not true of 
Ethernet and Thinwire Ethernet).


I wondered if the "line" was the wrong term here and that you actually 
meant antenna wire, in which case, if the transmitter is directly 
connected to ground (no appreciable length of ground wire, the answer is 
going to be an electrical quarter wave, which is of the order of 20.5 
metres or slightly less.



with ATU? I'm having a heck of a time trying to find a length that will work
with 80M and 40, 30 and 20. I know the ATU is not really designed to tune
80M effectively. It would be nice to have one antenna to do all bands, but
if not a separate wire for 80M is okay too.
