[Elecraft] K3 Question on Bandwidth setting via Macro

[John Klewer]

I have a macro which, while configuring my K3S for FT8 operation, sets BW
to 4.0 kHz.the 6.0 kHz roofing filter is (apparently) automatically
selected and I do not actually realize 4-ish kHz BW until I manually select
the 13 kHz roofing filter.

It seems from the Programmer's reference that the XFIL function is a Get
not Set function.

I would appreciate anyone who would set me straight on either what I am
doing wrong or if this is a "problem" that can't actually be solved with
the firmware/hardware as constituted.

Thanks in advance

John, N6AX

Don,

I think there may have been a software utility in the past which allowed 
you to do something like you were trying, but I may be thinking of the 
KRC2 utility instead.


I am glad to hear that you are working OK now.

All better.

Don,

There is no selection of a "group of bands" - but you can select
the proper antenna for any one band.  Once you have done that,
change bands and select the desired antenna for that band.  When
you have covered all bands of interest and selected the antennas
for each, is the proper antenna selected when you switch to that
band?  If so, all should be well.

Did I misunderstand something in your question?

Re: [Elecraft] K3 Question on KXV3B

[N2TK, Tony]

Hi Ross,
Nope. Wayne got it right as to what I was asking about.
I have one external 6/10M preamp now. Will replace with the internal KXV3B
for both K3's. Makes it cleaner. And I never use both preamps at the same
time anyways.

Have a great weekend.

 Preamp 2, on the KXV3B, is in addition to the normal preamp (preamp 1).
But firmware will only let you turn on one or the other -- not both. When
preamp 2 is ON, it totally dominates the noise figure equation, so there's
no value in also turning on preamp 1. Preamp 2 has a gain of 20 dB, while
preamp 1 has a gain of 10 dB.

 To turn preamp 2 ON, you first have to enable it on one or more of the
applicable bands using the CONFIG:PREAMP2 menu entry. You can enable it on
12, 10, and 6 meters.

 Once preamp 2 is enabled, tapping PRE cycles through OFF/PRE1/PRE2 on the
applicable band. Other bands will only show OFF/PRE1.

 When PRE2 is selected, the PRE icon flashes slowly as a reminder.

[Elecraft] K3 Question: AFSK-A or DATA-A for RTTY?

[James Bennett]

I've been a PSK31 user just about ever since the mode came to be. Not a heavy 
user, but couple time a month I get on and have some nice keyboard QSO's. In 
the 50 years that I've been licensed, I have NEVER made a RTTY QSO! However, it 
does intrigue me so I started messing with it a little this week.

I recently got a new external sound card for my station - a Tascam US125. It is 
connected to my iMac via USB and the K3 via a pair of stereo cables. Works fine 
on JT65, JT9, and PSK31. I use WSJT-X for the JT-modes and cocoaModem (CM) for 
PSK31. CM also provides RTTY so I gave it a shot. After a few burps I got it 
going.

With PSK31 and the JT-modes, I've always had the K3 in DATA-A setting. RTTY 
seems to work in either DATA-A or AFSK-A. Fred Cady's K3 book states that 
AFSK-A is optimized for RTTY. How? What is the real benefit to switching to 
AFSK-A mode for RTTY? Is that what everyone is using, or is DATA-A just as good?

Thanks, Jim / W6JHB

Re: [Elecraft] K3 Question: AFSK-A or DATA-A for RTTY?

[Bill Frantz]

I find myself switching between Data A and AFSK-A quite a bit. 
The RTTY dual passband DSP filter (DUAL PB) can help a lot with 
QRM from nearby RTTY signals, and it eliminates much of the 
off-frequency noise. You can also turn on TEXT DEC to get the K3 
to decode the RTTY, giving you another chance with weak signals.


With cocoaModem I am always using the RTTY, rather than the 
Wideband RTTY or Dual RTTY options. The crossed loop tuning aid 
can't be beat. It simulates the CRT based tuning indicators used 
with hardware RTTY receivers.

Re: [Elecraft] K3 Question: AFSK-A or DATA-A for RTTY?

[Don Wilhelm]

Jim, and all,

Yes, the AFSK A data submode is optimized for RTTY operation.  The 
default sideband is LSB and the use of the dual filter is possible. 
Furthermore, the K3 dial display shows the mark frequency.
If you are using an RTTY mode with an application such as MMTTY, you 
will find the AFSK A mode useful and tuning will be done using the K3 VFO.


OTOH, if you are using an application that has a waterfall display and 
does point and click on the preferred signal (rather than tuning to the 
signal with the K3 VFO), then the use of DATA A in reverse mode will 
likely be more useful to you for RTTY - your application may switch 
sidebands when RTTY is selected - check the documentation for your 
application, it is a 'mixed bag' and some application 'do it right' 
without explicit actions by the user while others will require that LSB 
be explicitly selected.  The frequency display on the waterfall is also 
application dependent.  Refer to the application documentation to assist 
in understanding what is being displayed on both the transceiver 
frequency display and on the waterfall.


For data modes other than RTTY, yes, DATA A should be used - it all 
depends on the data mode application.

Yes, AFSK A is the way to go, and it works very well with VOX! Note also 
that in the last year or two, authorities say the dual passband and 
narrow filters are a bad idea, and recommend 400 Hz bandwidth IF. The 
problem with dual passband and narrow filters is phase shift, which 
degrades decoding. Many top RTTY contesters have taken that advice.

Hi Jim,

I read other folks responses without seeing your original post. Sorry  
about that. To use AFSK, you need a single decoder program like MMTTY 
that operates much like you would on CW and SSB, tuning up and down the 
bands with a narrow-band receiver. This is the standard for contesting 
and DXing, and it permits the RX to be very narrow, so that it is much 
less bothered by QRM. DATA-A is for multi-decoder programs like you have 
been using, and you may find it more satisfactory for general use in the 
same way you use WSJT-X and PSK31 software. Or maybe not. The major 
difference between RTTY and other digital modes is that there are no 
standard dial frequencies like there are for JT65, JT9, and PSK31. RTTY 
ops generally range all over the band, especially during contests, and 
also for DX operations.


So the best answer to your question is that DATA-A is for dial 
frequency operation like JT65 and PSK31, whereas AFSK-A is for tuning 
up and down like a CW op.

[Elecraft] K3: Question about data modes...

[David Cole]

Hi all,

What EXACTLY is the difference between AFSK A, and DATA A.  

Here is why I ask:

In AFSK A Mode:
While using MixW, and looking at the MixW screen, and in USB on the K3,
as I tune using the knob, the MixW screen shows the signal stuck to a
frequency on the top calibration marks on MixW.  The signal never moves
from the frequency indicated on the MixW software in the waterfall.

In DATA A Mode:
All settings the same with the exception of switching from AFSK A to
DATA A.  The signal moves relative to the frequency marks on MixW.  i.e.
if the signal started at 14., as I tune the knob, MixW tracks the
frequency, moving the scale above the waterfall, while the signal
appears to move independently of the waterfall calibration marks...  

I have tried REV sideband on the K3, and the same thing still
happens...  

Is there a resource I can read telling me EXACTLY what each data mode
does?  I have KE7X's book, and that does not explain why I am seeing
what I am seeing...  At least not to me...  I am putting my macros
together, and need to get my head around EXACTLY what the two modes do,
as they set up the radio.

Re: [Elecraft] K3: Question about data modes...

[Joe Subich, W4TV]

In simple terms:

AFSK A is LSB, AFSK TX filter (MENU: AFSK TX) is available and
controlled by PITCH (Mark), audio input uses data selection.
TX and RX EQ are disabled.  Receive dual tone (dual peak) filter
is available.  Frequency (VFO) display reflects *MARK*

Hi all,

Here is why I ask:

frequency on the top calibration marks on MixW.  The signal never moves
from the frequency indicated on the MixW software in the waterfall.

In DATA A Mode:
All settings the same with the exception of switching from AFSK A to

if the signal started at 14., as I tune the knob, MixW tracks the

I have tried REV sideband on the K3, and the same thing still
happens...

Re: [Elecraft] K3: Question about data modes...

[Don Wilhelm]

David,

AFSK A is optimized for use with RTTY.  It defaults to LSB and the 
frequency displayed is the frequency of the Mark tone.  The latter 
feature does not make too much sense to me when using a waterfall 
display, but it makes a lot of sense when using narrow filters and 
tuning to a RTTY station with the VFO.  If one arranges  sked with an 
RTTY station, the sked frequency will normally be given as the mark 
frequency.


Data A is the best to use for those soundcard data modes where a 
waterfall display is used.  It defaults to the usual USB used for many 
data modes.  The K3 frequency display is the frequency of the suppressed 
carrier.

Re: [Elecraft] K3: Question about data modes...

[David Cole]

Joe,
Is there something else that might explain the actions of the signal in
the waterfall of MixW?  

I have tried DATA A in REV sideband, (I thought that would fix the
issue), and the signal does not stay pinned to the same frequency under
the MixW calibration marks...  As I tune up, MixW moves the calibration
marks, but the signal moves in the opposite direction...  This happens
no matter if in REV or not, In DATA A, it never tracks correctly.  If I
reach over and switch to AFSK A, it tracks as expected...  Stays pinned
to the frequency marker, which is moved as I tune.

I would expect that only changing to REV would correct this, but it does
not.  Hence why I question my understanding...

Re: [Elecraft] K3: Question about data modes...

[David Cole]

Hi Joe,
I was thinking that as well, but MixW is using USB.  As a test I
reversed the sideband by pressing the mode until I saw REV pop up.  I
would have expected that to correct the issue if the software were on
the wrong sideband, but it just makes it fail the opposite
direction...  

My belief tells me that I should be able to reverse sideband on the
radio, and reverse sideband on the software and it should still work...
Is that a correct understanding?  What drives me nuts is that I have it
working for CW and RTTY, both use LSB...  I use DATA A for and USB on
the radio for JT65 and that works.  My only issue is with PSK...  Maybe
because PSK works in USB or LSB the software, (MixW), defaults to LSB,
no matter how it is set.

Re: [Elecraft] K3: Question about data modes...

[Richard Ferch]

It's been quite a few years since I used MixW, but here goes:

1. Last time I tried it, MixW did not understand the K3's digital 
sub-modes. Basically it acted as if they were all the same (either FSK D 
or AFSK A), i.e. on LSB. Even when I put the rig in DATA A, MixW still 
acted as though the radio was in LSB.


2. If the waterfall is in Auto mode, MixW recognizes when the rig is in 
REV, and automatically adjusts its sideband to accommodate the switch. 
In other words, if it was on the wrong sideband without REV, after 
entering REV MixW automatically changes its sideband so it will still be 
on the wrong sideband. The solution to this is to take MixW out of Auto 
mode and force the waterfall to be in USB regardless of whether the 
radio is in REV or not.


3. One other problem is the frequency offset: in FSK D and AFSK A , the 
K3's dial displays the Mark frequency, whereas in DATA A it displays the 
suppressed carrier frequency. Therefore you may need to supply a 
frequency offset to get MixW to display the correct frequency.


My recollection was that I was able to configure MixW either to work 
correctly in AFSK A/FSK D, or in DATA A, but not in both, at least not 
without making configuration changes when I changed data sub-modes. I 
have no idea whether the current version is any different, but your 
experience suggests that it may still have this problem.

[Elecraft] K3: Question on Replacing the Front Panel 28 and 5 Pin Connectors; Need the Elecraft Instructions

[David and Dianne on Comcast]

Hi All,

Last fall I replaced the PA connectors in my K3 
with the Elecraft gold plated pin connectors that 
they recommend.


Recently I have also acquired the gold replacement 
28 and 5 pin connectors for the front panel of my 
early K3.


But I have misplaced the PDF instructions that 
Elecraft sent or e-mailed me with the pins.


Can anyone e-mail that PDF instruction sheet or 
provide a URL link to it?


I cannot find it on the Elecraft site.

I would be grateful for any assistance.

[Elecraft] [K3] Question for those using a K3/100 as a transmitter and a remote station terminal

[Barry]

From what I see on the Elecraft web site, the Remoterig modem uses a serial
connection with a K3.

If you have the K3 hooked up to a P3 and/or computer for home station use,
do you use a serial A/B switch or some other method to switch it to use as a
remote station terminal?  Be interested in hearing the details of such a
setup.

Tnx,
Barry W2UP

No need for any switching... the P3 can be inserted between the K3 and
the RRC box. The computer can plug into the other serial port (COM1)
on the RRC box for local rig-control, or it can talk through a USB
connection to the RRC instead (including rig-control). You would need
to bypass the RRC box for K3 firmware upgrades, but that's infrequent
enough that you can just temporarily move the cables around

I think you mean it goes from 60M to 30M without stopping at 40.  If that's
what you meant to type, then I bet the config menu item BND MAP has 40
inadvertently included.

-Original Message-

I'm planning on running the Minnesota QSO party with one of my K3s in the  
car.  Would appreciate any and all QSO's--see   W0AA.org   for information 
on the contest--just Saturday, Feb 2, 8 a.m. CST to 6 p.m.  CST.  
 
My question is that I can't figure out why,  when I tap up band  or down
band, I can't get 40 meters!  It goes from 30 meters to 20  meters both
directions without stopping at 40!  I usually don't use these  buttons but
with my old lap top, I need to.  Of course I can key in the  frequency, and
usually can type it in to the logging program, but for some  reason that
doesn't work with my old dos laptop running NA.  
 
Any suggestions?

[Elecraft] K3 question, PSK and AM filter option from G4HUE

[ANDY NEHAN]

Happy Xmas guys and a healthy and prosperous New Year to all.

I am
a recent convert to the K3 with model 6990.
 
I am primarily a data mode operator (PSK31 etc. etc.) and my
K3 has the 2.8KHz and 250Hz 8 pole filters fitted and let me say its doing a
very fine job too. I use HRD version 5 which appears to force the sound card to
sample at 8KHz (in my case it’s the Signalink USB). My question is that I would
like to be able to simultaneously decode more than 2.8KHz (HRD is limited to 
3.9KHz) of the ham band at once.
I have thought about fitting the 6KHz AM filter (there not being a 4KHz filter
available). One part of me says that would work just fine and the other part of
me says “don’t be silly” there will be 3KHz of LSB and 3KHz of USB and it will
all go horribly wrong. I guess someone out there has tried and can tell me
which of my premonitions is correct?? As a suplementary will this be limited by 
any audio filtering in the K3, I seem to recall reading that the K3's audio is 
limited to a bandwidth of 4.2KHz but of course I can find the reference now!!

 
Thanks in advance guys.

Andy

I don't think your premonitions are correct abut things going terribly
wrong.  However, my feeling is why bother?  The K3 transmit audio in
DATA A rolls off significantly below roughly 300 Hz and above 3000 Hz
(maybe 200/2900 Hz it's been a while since I tested it) thus any RX
bandwidth above 3 KHz would be receive only.

The 2800 Hz/8 pole filter is about 2900 Hz or slightly wider at the
-6DB points in any case and will have significant response on the
filter skirts so you will certainly find response to 3.9 KHz if you
set the DSP to allow it (even though the response may be down a fair
bit).


As a suplementary will this be limited by any audio filtering in the
K3, I seem to recall reading that the K3's audio is limited to a
bandwidth of 4.2KHz but of course I can find the reference now!!


The DSP is limited to approximately 4.2 KHz output.  The DAC which
feeds the headphone and speaker outputs is followed by a lowpass
filter at 4.2 KHz to remove clock leakage and other artifacts.
Although the DAC which feeds the Line Out does not also include
a LPF, the DSP programming is the same including the 4.2 KHz
cutoff.

[Elecraft] K3 question

[k6rb]

I noticed the other night that when I was using one of my two K3s on 80 m
CW, in full QSK, there would be occasional snap-like audio sounds and I
would lose sidetone during a computer-keyed interval. The radio was still
putting out a signal but the sidetone and between-character RX signals
were muted too, until the sequence completed. I'm not sure it's related,
but occasionally that same K3 - on 80 m CW - causes repeated soft faulting
of the Alpha 87A it drives. I thought maybe something was screwy with the
antenna or feeds, but I switched to the other K3 driving a KPA-500, and
had nothing like that snapping sound and audio muting. Anyone have a clue?

Re: [Elecraft] K3 question

[Don Wilhelm]

Rob,

Too many variables to give a good answer.
Consider that the K3 plus Alpha 87A might be giving you RF Feedback 
which will createstrange happenings.  The real question is -- Does 
the same thing happen when driving a dummy load?   If the answer is 
NO, then look for the solution in your antenna system.

Note that I normally respond to conditions where the transmitter is 
driving a dummy load.  Other situations do exist, but may or may not be 
the problem - it all depends, and the input impedance of the antenna is 
a variable that can create erroneous information to be injected into the 
equation.  KISS - Keep It Simple Stupid is always a good goal, it 
reduces the number of variables.

Re: [Elecraft] K3 question

[Gary Hinson]

It is surely possible with an external RF changeover relay, switched from
the PTT line.   Don't know if it can be done within the K3 though.

Re: [Elecraft] K3 question

Write a macro in whatever rig control program you use to simulate pushing the 
ANT button when you transition from RX-TX-RX.  Of course I don't understand why 
you would receive better on one antenna and transmit better on another.

Re: [Elecraft] K3 question

[Don Wilhelm]

John,

Cannot do that, but if you have the KXV3 installed, you can use the RX 
antenna input.
There is benefit in that approach - you cannot transmit into your 
receive antenna and its preamps are safe.

Re: [Elecraft] K3 question

[Joe Subich, W4TV]

  Of course I don't understand why you would receive better on one
  antenna and transmit better on another.

Simple ... quite often my vertical is very noisy on receive and I
can hear much better on my 80/40 trap inverted V on the bands the
vertical covers.  However, I still need to transmit on the vertical.
While it would certainly be possible to move the the wire to the
RX Ant input on the KXV-3, it is quite inconvenient to do so.

Re: [Elecraft] K3 question

[David Gilbert]

There is a very simple answer for that.  All you care about for receive 
is signal-to-noise ratio on YOUR end of the path... efficiency is 
irrelevant because there is usually plenty of gain in any modern 
receiver, and if there isn't enough gain a simple low noise preamp fills 
in nicely.  That means any antenna with a good enough pattern (or the 
right polarity) to discriminate against noise will usually make a good 
receive antenna.   Beverages and various loop configurations (K9AY, 
pennants, etc) work well for that but they are very lossy and don't make 
good transmit antennas.

For transmit, you care about signal-to-noise ratio on the FAR end of the 
path, and since you have no control over the noise over there you can 
only try to optimize your signal strength.  The efficiency of your 
transmit antenna/feedline/etc is the first priority, with directional 
gain from pattern also being desirable.  For some bands, you can get 
both transmit efficiency and receive noise discrimination from the same 
antenna, but for the low bands that is pretty difficult to do without 
devoting the space and money to some sort of monster array.

For good antenna efficiency you almost always need size or height that 
is an appreciable percent of a wavelength ... for good pattern you often 
don't.

[Elecraft] [K3] Question about APF with Diversity Rx enabled

[Doug Joyce]

GA:  Perhaps someone (Wayne or Lyle or ??) could provide some further 
explanation about how the APF is implemented when Diversity RX is turned on.  
As I understand it, (at a high level) with Diversity turned on, both the MainRx 
and SubRx are turned on, use the same bandwidth roofing filters and the main 
VFO A provides the same LO signal for both receivers resulting in audio from 
the MainRx going to the left ear and the SubRx audio going to the right ear.  
If the APF is now turned on, does the DSP1 for the MainRx and DSP2 for the 
SubRx now apply that filter functionality to the two separate Main and SubRx 
audio signals so that turning the shift knob actually tunes the peak in both of 
the separate audio streams together?

I'm just trying to get a better understanding of what's going on in the radio.

Thanks and HNY to all.

Yes, but both VFOs share the VCO reference (i.e. not VFO A driving 
VFO B).  Both VFOs are always tuned together by the DSPs and MCU when 
in diversity mode.

[Elecraft] K3 question

[bill wade, sr.]

I have a K3 100 watt transceiver. The amp is a SG500. I use the power 
set per band  from the config menu to store drive settings 
independently for each band.

Is there any way to set up the K3 so that one can switch on the fly from 
barefoot operation to the amp without going through the necessary manual 
steps?

[Elecraft] k3 QUESTION AD5SX

[PEN4WWZ]

Hi Gary,
 
Just a little more feedback. For the fun of it I tried manual  tuning 
through the bands @ 50 watts and found that the tuning power on 40  meters 
through 10 meters did not fluctuate using the XMIT/Tune button. All other  
bands 
did.
 
Thanks,

[Elecraft] K3 question -- Transmitting (SSB) with power set to 0.0 watts -- any risk?

[Mitch Mitchell]

Hello,

 

I am chasing down a noise source that I hear when transmitting voice and data 
modes on my K3.   I trying some experiments to nail down the source, but while 
doing so I need to leave the K3 on transmit for a (relatively) extended period 
so I can hear any changes in the characteristics of the noise as I turn 
circuits on and off In the house.Will transmitting SSB with power set to 
zero for say 10 or 20 minutes cause any problems for the K3?

 

Thanks!

[Elecraft] K3 question to those who have upgraded their DSP board

[K2MK]

I've noted several recent postings from those that have upgraded their DSP 
board (which I assume included the LP filter board). Each has said that the 
new board sounds great. I wonder if those folks could be a bit more specific 
in order to help those of us on the fence. Has it improved CW or SSB? Has it 
improved fidelity? Reduced noise? Speaker or headphones? Any other thoughts?

Has it improved fidelity? Reduced noise? ...Speaker or headphones?

I ask as seemingly on the reflector I picked up that (LPF asisde?)
improvements to the DSP board audio affected the Headphone output.  The
improvements to Speaker and Line Out were those made on the main board.
 
If the above is the case, does the LPF affect ALL audio outputs?

[lyle johnson]

 If the above is the case, does the LPF affect ALL audio outputs?
 
 Will Elecraft or someone clarify this?

The LPF affects PHONES (fropnt and rear) and SPEAKER only.  It does not affect 
LINE OUT.

The component value changes improve headphone out (front and rear) low 
frequency response by changing the 10 uF output coupling capacitors to 100 uF. 
 LINE OUT is not affected by this change, nor is speaker out.

Tx Audio low frequency response is improved for all external Tx audio sources 
(front Mic, rear Mic, LINE IN) by several componenet value changes.

The componenet value changes for Tx audio and headphone audio were 
incorporated in production radios several months ago.

[Elecraft] K3: Question about S-Meter Calibration

[Grant Youngman]

So, the S-Meter calibration instructions in the manual indicate that  
PRE should be on.  When calibration is done,  that means that a 50uV  
signal reads S-9 with PRE on .. but about S-7 with PRE off.  And then  
if the mode is changed from Normal to Absolute, a 50uV signal reads  
S-7 with or without the preamp.

Just wondering (maybe I need to RTFM and specs again), why that would  
be the case, vs. 50uV being S-9 without the preamp.  I have always  
just ignored the instruction manual, and calibrated to S-9 with the  
preamp off.  So a 50uV signal reads S-9 (with or without preamp  
engaged if the mode is Absolute).

Am I screwing something up?  Or does it just not matter all that much  
since (1) it doesn't impact anything other than the bar graph, (2) an  
S-meter reading is not all that terribly important anyway (I don't run  
a lab),  (3) it's all relative, (4) the P3 is in my future, and (5)  
all DX or contest exchanges are 5-9 by definition  :-)

To set the record straight on a related topic -- I posted about an  
issue with gain calibration using the updated K3UtilityOSX a couple of  
days ago.  Turned out it was apparently nothing more than cockpit  
error and fat-fingers on my part, which is typical.  Dave Fleming and  
Elecraft support (Gary Surrency) were both very helpful and got me set  
on the path of truth and light ...

Anyone have any insight on the S-meter cal thing?

Thanks ... Grant/NQ5T

Yes.  In the end, you must calibrate the S Meter for how you use it. I 
operate in ABS mode, so I have PRE OFF and ATT OFF when I do the S Meter 
cal using a -73 dBm (50 uV) source.  I could leave PRE ON in thie mode, 
but I know that the DSP is adding an offset when I do that (as it does 
for ATT), so I calibrate with both OFF.

If I then go to the other S Meter mode, it is inaccurate, of course.

 Just wondering (maybe I need to RTFM and specs again), why that would  
 be the case, vs. 50uV being S-9 without the preamp.  I have always  
 just ignored the instruction manual, and calibrated to S-9 with the  
 preamp off.  So a 50uV signal reads S-9 (with or without preamp  
 engaged if the mode is Absolute).

Correct.

***

When you do the RF Gain Calibration procedure, it is important to know 
that your signal source is -73 dBm (50 uV).  If you use the S Meter to 
make this determination, you need to know how it was calibrated.

Re: [Elecraft] K3: Question about S-Meter Calibration

[Don Wilhelm]

Grant,

Mine does the same thing as yours - it appears as though the S-meter 
'abs' setting is the same as S-meter 'nor' with the preamp OFF.  So what 
I did was calibrate the S-meter with the preamp OFF and then set it to 
'abs'.
Makes sense to me, after all S-9 is supposed to be a 50 uV signal at the 
antenna.

As an additional point - I had to do a lot of 'fiddlin' to get the 
S-meter calibrated with the preamp on.  With the preamp off, my K3 
S-meter parameters are set right at the default values.

Grant, on an earlier thread on this general topic Wayne said that 
SMTR OF and SC may need further tweaking when switching to Abs 
after first aligning in Nor mode with Pre on.   My experience mimics yours. 
With a 50uv signal and the S meter at S9, Nor OF setting is 30 and Abs
setting is at 23.  So that's quite a tweak. 

I prefer Abs, having gotten used to the idea with my Omni VII.  I'm not
sure why it is recommended that the alignment first occur in Nor mode
unless what you and I are seeing is abnormal.  It is almost as if the
settings
are independent except for SC which is 14 in both cases. So, no insight,
just a similar experience.

Gary W7TEA
K3 #1001


So, the S-Meter calibration instructions in the manual indicate that  
PRE should be on.  When calibration is done,  that means that a 50uV  
signal reads S-9 with PRE on .. but about S-7 with PRE off.  And then  
if the mode is changed from Normal to Absolute, a 50uV signal reads  
S-7 with or without the preamp.

Just wondering (maybe I need to RTFM and specs again), why that would  
be the case, vs. 50uV being S-9 without the preamp.  I have always  
just ignored the instruction manual, and calibrated to S-9 with the  
preamp off.  So a 50uV signal reads S-9 (with or without preamp  
engaged if the mode is Absolute).

Am I screwing something up?  Or does it just not matter all that much  
since (1) it doesn't impact anything other than the bar graph, (2) an  
S-meter reading is not all that terribly important anyway (I don't run  
a lab),  (3) it's all relative, (4) the P3 is in my future, and (5)  
all DX or contest exchanges are 5-9 by definition  :-)

To set the record straight on a related topic -- I posted about an  
issue with gain calibration using the updated K3UtilityOSX a couple of  
days ago.  Turned out it was apparently nothing more than cockpit  
error and fat-fingers on my part, which is typical.  Dave Fleming and  
Elecraft support (Gary Surrency) were both very helpful and got me set  
on the path of truth and light ...

Anyone have any insight on the S-meter cal thing?

Thanks ... Grant/NQ5T

[Elecraft] K3: Question on ESSB TX EQ

[Grant Youngman]

The manual indicates than when ESSB is turned on, the TX EQ menu  
function becomes TX* EQ (or something along those lines).  I don't see  
that happening.

Did I miss something, or is this one of those features still to be  
implemented?

[Elecraft] K3 question: setting monitor level via serial port command?

[Dana Roode]

Hi all,

Does anyone know if there is a K3 serial port command to set the
monitor level?  I am using my K3 remotely and inadvertently set the CW
monitor level to 0 before I left my station today (it is 80 miles
away).  I have not seen a way to control this via TRX-Manager or Ham
Radio Deluxe.  I looked through the K3 Programmers Reference and
didn't spot it there either.

  Dana, K6NR

[Elecraft] K3 question--TCXO or another filter?

[Steve Ward]

Greetings all,

I'm getting pretty close to the time I'm expecting to see a Katiegram, 
and I'm thinking about adding either the TCXO or the 6KHz filter to my 
order.


I do a lot of PSK-31 and I'm wondering if most folks find the stock 
oscillator sufficiently stable for digital or if the TCXO is better to have?


Thanks for your advice,

Steve

Given that the regular oscillator in the K3 is better than many if not
most amateur radio HF transceivers, I do not believe you will see a
noticeable improvement with the higher quality TXCO. As far as I know
the typical HF user will not notice any improvement by having the TCXO
in standard (sane?) operating conditions at HF to 6 meter frequencies.
So in short, the stock K3 is more than adequate for PSK-31 operating.

The stock XO is  +/- 5 ppm (0-50 C) TCXO standard (@49.380 MHz). The
upgrade is to +/- 1ppm. The average user won't notice the +/- 4Hz
improvement. I believe many users would have issues accurately
calibrating their K3 to +/- 1ppm. As far as I know _reception_ of
WWV/CHU's HF (or WWVB LF) signals are not that accurate. A GPSDO (GPS
disciplined ovenized oscillator) would be typically used to in that
situation.

My understanding is that beside amateur metrologists (e.g. time-nuts),
and the typical users of the upgraded TCXO are microwave perhaps
mobile/rover VHF operators who use transverters to multiply the K3 HF
output to the higher operating frequency, where you want minimal error
(i.e. drift, jitter) in the K3's oscillator, because this error will
be magnified (multiplied) by transverter as well.

not while they are shipping the first batches.

 again.  If you want to try an alternate to audible zero-beat, see below 
 - there will be no confusion about whether you are zero beating a WWV 
 tone or the carrier.
 
 You might try an alternate to the Zero-Beating method by connecting the 
 K3 to a computer running Spectrogram.  Tune the receiver in LSB or USB 
 mode to 10.000.000 and listen to the WWV signal - put markers (pointers) 
 in Spectrogram at 500 Hz and 600 Hz.  WWV transmits one of these tones 
 on alternate minutes.
 
 Then enter the CONFIG menu and find REF CAL.  Tune the VFO A knob until 
 the tones from WWV line up with the markers in Spectrogram.
 
 I consider the above method more accurate than using a frequency counter 
 of unknown calibration.  Of course the audible zero-beat method works 
 fine too, but there is always the possibility of confusion about whether 
 one is zeroing the carrier or one of the transmitted tones.  The warning 
 about being certain you are zeroing the carrier goes back to the days 
 when we were calibrating our secondary frequency standards - one must 
 wait for a silent minute to be certain we zero the carrier.

I haven't had a problem with the WWV tones. I first zero on WWV, then wait
for the announcement that takes place at the end of every minute. While the
announcers are giving the id and time, I check to be sure I am zero with the
carrier (move REF OSC off frequency and make sure the beat reappears).
There's plenty of time to do that during the announcement period. Even I
need a bit longer, there's another announcement period 45 seconds later to
check again. 

Of course, virtually ANY AM broadcast station will be on frequency too.
After setting up on a BC band AM station, you can double check your zero
beat on WWV if you like. Remember, you have to be a full 400 or 600 Hz off
frequency before you're in danger of zero beating with the WWV tones by
accident and, typically, you'll be within 1 or 2 Hz after zero beating to
any AM station.

Re: [Elecraft] K3 question/problem

[Robert Brigham]

Elecrafters,
Another tool that I have used sometime to suppliment
the Spectrogram program is the waterfall display of
Digipan (or any of the similar PSK31 programs). For
example, the waterfall display shows the time
dependence of the WWV components making it easy to
identify the carrier (center band) and the modulated
components which appear symmetrically on either side.
It was also a big help setting up the RTTY filters for
PSK31.

[Elecraft] K3 question/problem

[H. Cary III]

I hesitate to put this question on the reflector but support at Elecraft is 
closed until Wednesday, Jan. 2 - understandable, they DO deserve some time off!

The assembly of K3-100 (#178) is complete and went very smoothly...all tests 
checked out flawlessly, the filters are properly aligned per the calibration 
instructions (offsets, proper mode, etc).  I have done the frequency 
synthesizer alignment using the zero beat with WWV but when I tune WWV at 10 
MHz, I have to get the dial to about 9.999.92 or so to be right on it.

I have a sked on Sundays with two friends, W5ZNN and WA6EBB, and was hoping to 
have my K3 operational so they'd be my first contacts.  Well, in a sense they 
were but apparently my signal is about 500 hertz higher than my receive 
frequency AND the audio sounds narrow and broken.  I think the problem may be

Re: [Elecraft] K3 question/problem

[Toby Deinhardt]

Hi Cary,


 I hesitate to put this question on the reflector

This what the reflector is for!


 apparently my signal is about 500 hertz higher

You ought to double check which filters you have set up for TX for each 
mode. It sounds to me as if you might have a small fubar in your filter 
settings. When in doubt, use the 2.7kHz (or the 2.8khz, as the case may 
be) for all modes apart from AM. Here you need to use the 6kHz filter, 
if you have it.


Also double check that you do not have + and - mixed up on the filter 
offsets. AFAIK no filter offsets are needed for the 8 pole filters.



Happy New Year.

[Elecraft] [K3] Question about TX gain calibration

[Toby Deinhardt]

Now that I know that my K3 will soon be here, I am rereading the manuals 
and have run into to something I'm not sure I really understand.


When doing the TX gain calibration (page 46/47 of the Owner's Manual):

1) Does TECH MD have to be on or off? I assume on.

2) Does one need to be in the TXGN menu?

3) Set Power to exactly 5/50/.001 watts somewhere in the K3 display or 
adjust power until the reading on the external (hopefully) accurate RF 
power meter is 5/50/.001 watts? And then check the reading on the VFO-B 
display?


4) Go to next band and repeat 3...

I'm sure it's really simple, but at times I can be a bit dense...

[Ed Muns]

 When doing the TX gain calibration (page 46/47 of the Owner's Manual):
 
 1) Does TECH MD have to be on or off? I assume on.

No.  All TECH MD does is allow you to view more parameters in the CONFIG
menu, but that is irrelevant to this calibration procedure.

 2) Does one need to be in the TXGN menu?

No.

 3) Set Power to exactly 5/50/.001 watts somewhere in the K3 
 display or adjust power until the reading on the external 
 (hopefully) accurate RF power meter is 5/50/.001 watts? And 
 then check the reading on the VFO-B display?

Turn the POWER control to set power at 5 or 50 watts.  Hold TUNE and let it
run for 1-2 seconds (until the power display settles).

 4) Go to next band and repeat 3...

Yes.

RE: [Elecraft] [K3] Question about TX gain calibration

[Tom Hammond]

Toby:

For what it may be worth... I saved a LOT of time running this sequence by
performing ALL of the 5W calibrations at one time... leaving the power set
to 5W and running through each band... then, resetting power to 50W and
running through each band again.

MUCH FASTER than having the jump from 5W to 50W on EACH band as you step
from band to band.

And there is no difference in the calibration.

[Elecraft] K3 Question Assembled/Kit

[Lee Buller]

As I have been reading the preliminary manual (wow!) I started to wonder about 
a couple of things

I know the Kit has no alignment to do.  How do they do that?  Do they put it 
all together and align it...and then ship itor does E just do put the 
PCBs on a test bench and tweak it?  I would think it would more cost 
effective to to the test bench.

If the test bench method is usedare there any stats on the difference in 
alignment between a Kit and and Assembled unit.  Does the Kit need to be 
tweaked to get the same alignment as the Assembled unit?


Will there be a different serial number for K3s that tell them apart from a Kit 
or an Assembled unit?  SN-134768K  or SN- 134768A? 

I bet this has already been discussed herebut I cannot keep up with the 
volume of email and all the information.  Overload!

RE: [Elecraft] K3 Question

[Brett gazdzinski]

 I plan on eventually getting the 2nd receiver, as I think
all sorts of cool things can/will eventually be done with the K3
in respect to the diversity thing.

Maybe even a noise nuller type setup where you have a noise antenna
that picks up local noise and eliminates it.

Diversity itself would be great, 2 different antennas can
act very different under QSB situations.

I have actually switched between the G5RV and the vertical
antenna manually during slow QSB situations!

 weak-signal reception using two separate antennas.

I'd order the second receiver in an instant if that option became a reality.

If you order KXV-3 transverter interface with the K3, you get antenna 
in/out jacks. This is very handy for connecting such things as bandpass 
filters or noise cancellers. It allows you to insert something in the 
receiver antenna path.


I have an MFJ noise canceller which is designed to work with a 
transceiver. It has a slow, clunky bypass relay which takes it out of 
the circuit when you transmit. Unfortunately, this relay only works (and 
poorly, at that) with semi-QSK. I stopped bothering with it as a result.


However, with the MFJ connected between the antenna in/out jacks, the K3 
takes care of the t/r switching.


The MFJ seems to work well with just its little whip for a noise antenna 
(it has a connector for a bigger antenna if you wish). Although it does 
not help with stuff like distant thunderstorms, it is effective for 
locally generated noises, like ethernet birdies, plasma TV noise, 
aquarium thermostats, power line noise, etc.


You need to diddle with the controls to null a noise. It doesn't always 
work, but sometimes it is a lifesaver.

[Elecraft] K3 Question

[Don Rasmussen]

Assume a non-contester is looking at a K3.

There would be no need for a second receiver nor the
absolute selectivity of the K3. Aside from those
points, can anyone suggest how the K3 might compare to
the Kenwood TS870?

K3 is new, '870 is at least several years old, possibly unknown history.
K3 synthesizer is quieter, and with selectivity options you're like to 
have less listening fatigue.

K3 covers 6m.
K3 is smaller/lighter/more portable.
K3 will be getting new features over the next several months/years. '870 
is what it is.
K3 makes it trivial - and fun! - to play with digital modes even if 
you're not a digital modes person.  '870 requires computer, soundcard 
interface,  etc. to even casually experience them.

K3 has manual notch in addition to autonotch/denoiser.
K3 has 8-band mic equalizer.
K3 has 8-band Rx equalizer.
K3 has better dynamic range.
K3 has lower power consumption.
K3 has excellent QSK.
If you have problems, K3 has excellent support.
K3 has...

[Elecraft] K3 Question

[Don Rasmussen]

Lyle - you are SHAMELESS. You could not find even one
thing to put in the TS870 column? ;-)

I used one for a short time at field day once, it
seemed like a nice enough radio but I preferred the
TS830 even though it was an older design. The 830 was
hybrid, which I rarely prefer in anything, but it
had a natural analog sound and no funny sounding
digital artifacts when you turned the front panel
controls. 

I'm hoping the K3 will sound more like an analog radio
while having the flexibility of a digital rig. We
already know there are fewer IF conversions so the AGC
should be better.

It may be that the larger benefits of the K3 are not
even in the superior numbers we expect. 

Still, some really enjoy the 870, I'll be interested
to see if the 870 lovers like K3 enough to change
radios.

While the second receiver would be good in
a contest, I'd think it would be more beneficial
to the DXer who wants to listen to both the
DX freq and tune around the pileup to see where
to call . without having to switch VFOs.

And, yes, the 870's front end does fold up quite
quickly under very loud adjacent stations.  But
not as bad as the 706s and 7000s!

By non-contester would you include DXer?  A second receive channel to  
monitor the pack when your calling a dx station on an offset is  essential.

[Elecraft] K3 question re dual receive

[Bill Tippett]

N6KR:
The KRX3 subreceiver can either share the main receiver's RF
path or get its signal from the unused KAT3 ATU antenna jack.

Can't we use the RX antenna port on the $79 KXV3?  This
is how I plan to use diversity.  One input being my
directional TX antenna and the other being a Beverage
on the KXV3 RX antenna input.  This is a less expensive
alternative for a second antenna input if you have no
need for the $289 KAT3, as is my case.  If I'm wrong,
I need to cancel my KXV3 and order a KAT3.

Yes, with the KXV3, you can select the RX antenna for either, or both,
receivers.
