Re: [Elecraft] New to Elecraft - help with audio settings

2017-04-09 Thread Walter Underwood
If the K3 manual is anything like the KX3 manual, it has steps for voice setup. 
Set everything to zero, set mic level, then the next step. I did this all wrong 
several times with my KX3, then finally read the manual carefully. Before that, 
it was random twiddling and no joy.

I collected the received wisdom from the Elecraft list and put together a blog 
post. Read the manual, then check this out for TX EQ settings. For the K3, you 
might need the DVR option to do to voice A/B (KDVR3).

[Elecraft] New to Elecraft - help with audio settings

2017-04-09 Thread Rob Monsipapa via Elecraft
Hello,
I just set up my K3, KPA500, KAT500 and P3.  Couldn't get any audio out until I 
changed the mic setting of the front mic connection to high output and no bias. 
 CMP settings is 11, MIC gain is 9 and power on the K3 is set at 28watts...  
It's now driving the amp up to around 500watts but I get NO readings on the CMP 
and ALC meters, none.  So I feel like I am missing something.  I'm using the 
Heil PR781 mic and need to make some EQ settings.  

If anyone can offer some suggestions I'd appreciate it.

[Elecraft] KX3: Trouble downloading new firmware

2017-04-09 Thread len
I thought I might update the firmware in my KX3 this afternoon.  I'm
currently running 2.38

 

I have my KX3 connected to my computer and running the KX3 utility.  The
communication is working fine with the radio.  When I click on the "Copy New
Files from Elecraft" button I get this:

 

Opening connection to ftp.elecraft.com

Opening connection to ftp.elecraft.com

Connected to Elecraft server

Please be patient, this takes a few seconds

Connected to Elecraft server

Please be patient, this takes a few seconds

InternetFindNextFile completed with error 0x0006: The handle is invalid.

 

I closed the KX3 Utility and retried, same result.  I've updated the
firmware several times before without issue.  I can get to the web Elecraft
site, as well as the ftp site, so it is not a connectivity issue.
Suggestions?

Re: [Elecraft] K3S SSB TX monitor - feature request

2017-04-09 Thread Wes Stewart
On morning (probably about 1980) I was beamed west at setting moon looking for 
Asia on 2M.  I heard a station calling CQ and said to myself, that's Dave's 
(W5UN) frequency.  Sure enough, it was Dave calling CQ.  So I tuned off him and 
heard another station calling CQ.  I listened and was surprised to hear Dave 
again.  I tuned back to the other frequency and Dave was still there, albeit 
with a different delay.  It finally dawned on me I was hearing him off the back 
of the antenna on tropo and off the moon from the front side.  Doppler and the 
time delay made it sound like two different stations.

I worked W5UN on two-way SSB on 2M EME.

A local friend, John, W7BBM, has a homebrew(!) 30 foot dish on 1296, and up, and 
routinely says, "Hello moon" and receives speaker-quality returns.

[Elecraft] NAQCC April Sprint this Tuesday Evening

2017-04-09 Thread Larry W2LJ
On Tuesday evening, April 11 (4/12 UTC), we will have our landmark 150th 
regular monthly sprint. 
 We want to celebrate this event by giving away a prize worth $150 to one 
member-participant! 
 But there is a catch, we will only have a prize drawing if we get at least 150 
submitted logs.  
You don’t have to be an experienced contester or a high speed CW operator to 
participate.  
Just get on the air, make at least 1 sprint QSO, and submit your log, and you 
will be eligible for the prize drawing.  
So mark your calendar and get ready!

EDT - 8:30-10:30PM, CDT - 7:30-9:30PM, MDT - 6:30-8:30PM, PDT - 5:30-7:30PM),
which translates as Wednesday, April 12th, 0030 to 0230Z in all cases.

For all the "official" information, please go to:

http://naqcc.info/sprint/sprint201704.html

There you will find all the details as to time, frequencies and other important
information.

This is a monthly event that caters to the CW veteran, the CW newcomer, straight
key and bug fans. All are welcome to participate (this includes QRO); but you
must use QRP power levels to compete for awards.

If you've been hesitant to join in our sprints because you hear other sprints
running at breakneck speeds, have no fear. Our sprints are geared to the
newcomer to CW and/or contesting. Virtually everyone including the many veteran
contesters who regularly enter our sprints will slow down to YOUR speed to help
you make your contacts.

If you are not already a member of NAQCC... membership is FREE! Now is your
chance to join the largest QRP CW Club in the world!! We currently have 7100+
members in: All 50 States - 9 VE Provinces - 100 Countries. Sign up on the
NAQCC website today (http://naqcc.info/) and receive a handsome certificate,
with your membership number on it, which is good for life.

Come join us and have a real good time!

Mel,

Guess you are unaware, but I am on 6m-eme, 2m-eme, and 23cm-eme. The RTLT is 
approx 2.5 seconds.  But voice is rarely used and emestations rarely operate in 
Duplex.  Of course one can receive yourown reflected signal for a short 
duration; that is called receiving yourecho.

Just supplemental comments to what Joe has written:

Having monitor of speech is certainly important for speaking properly
(or singing).  Note that speech able people who lose their hearing
slowly also loose the ability to talk properly.  If you are hard of
hearing you might talk too loud; happens to me on occasion; its just
your neural feedback loop doing "human ALC", as itwere.

For those who operate voice modes on satellites the time delay 
produced on monitoring your transmission with a full duplex station 
can get madding.  The delay is caused mainly by RTLT (round trip
light time) which is the time delay for the signal to travel round 
trip from the satellite.  For HEO (high Earth orbiting) satellites
the range gets to a point to experience significant delay in your 
voice monitored in the downlink Rx.  On AO-10/13/40 it could be
challenging to talk properly hearing your own voice delayed.  Iwould 
sound like: hello-ello, how-ow, are-re, you-ou.  Say that at anormal 
speaking rate and you will get the idea what it sounded like.

Full duplex operation is quite useful in satellite operating:
1.  Avoid talking on top of another station
2.  Making frequency adjustment for Doppler
3.  Verifying you have an adequate uplink into the system to beheard.

Many learned to compensate (mentally disregarding their own voice - 
which is difficult), or turning down the Monitored audio level when 
transmitting.

There we agree ... where the monitor level is set to be usable inthe
headphones, it does not cause a feedback issue even if the speakers
are turned on.  However, if one is using low sensitivityheadphones
with the speakers turned up high *and* high mic gain, one can cause
feedback or echo.  Rather than insisting on a change in the waythe
K3/K3S operates, one would be better served to repair the issues in
his own configuration!

Re: [Elecraft] K3 slightly off frequency

2017-04-09 Thread John Dolan
Also, Check to see that you are not on COARSE tuning.  In SSB mode, you can
easily be off frequency when the COARSE setting is chosen.  I have
experienced this recently and when I turned off coarse, I was able to tune
the rig onto frequency.   It seems that COARSE  had me in the "ball park"
but not quite on the correct frequency. The more I am using my k3S, the
more I am finding out about these things.

Re: [Elecraft] K3 slightly off frequency

2017-04-09 Thread Don Wilhelm

Mel,

The answer depends on whether or not you define "zero beat" correctly - 
which is to tune in the signal to the same pitch as your SPOT tone.


In other words, your statement "match my K3 frequency to his" is not 
sufficiently informative.  It all depends on how you match his 
frequency.  What the dial says on his transceiver is not relevant, the 
only thing important is what you are hearing.


Would it not be better (and easier) for you to change the PITCH of your 
SPOT tone to the pitch you like to hear?
That means there is no need to use RIT most of the time - if you tune 
the incoming signal to that same tone, you will be on the same 
frequency.  The K3 then uses that pitch as the center of the filter 
passband (unless SHIFT is set somewhere other than default) and is the 
pitch used for zero beating.


The normal use of RIT is when you have called CQ and a station comes 
back to you not exactly on your transmit frequency - RIT can then be 
used to tune that station in and not create a situation where the QSO 
"walks up the band" with each transmission - your TX frequency stays put 
and the other station's TX frequency also stays put.

Mel and all,

If you are talking about CW, then using RIT is a sure way to get the 
actual received frequency different than the transmitted frequency.  In 
fact, that is one easy way to define RIT.
During RX, the K3 will show the actual frequency (at your chosen

But if you have RIT or XIT turned on, the transmit frequency will be 
different than the receive frequency.

Hopefully your perception of "zerobeat" means that you have tuned the

attempt to tune to zero frequency (which is incorrect and will produce 
'strange' frequency readings).

Back in the day, Elecraft informed us about that cyclical error problem
with the old synthesizer. It would now be good to have a definitive
statement about the frequency setting accuracy in the new synthesizer. 

The same applies to the TCXO error correction by the KREF3 module. Since
corrections are applied by rewriting the declared value of the 48MHz
reference frequency, presumably this can still only be changed in 1Hz
increments.

A related question (raised by Don's post, just in) is the magnitude of
any difference between the displayed sidetone pitch and the actual value
within the synthesizer?

Re: [Elecraft] K3 slightly off frequency

2017-04-09 Thread Don Wilhelm

Dick,

It is easy to check your K3 or K3S (or any other radio).  I suggest you 
do so before concluding that your radio is off frequency.


Tune to WWV at the highest frequency you can receive in CW mode and zero 
beat the carrier - you can use CWT if you are not good at zero-beating.
Make sure you are zero-beating the carrier and not one of the 
transmitted tones.  The tones come and go minute by minute, but the 
carrier is always present.


Stations that cannot receive WWV can use of of the other standard 
stations around the world.


If your K3 is off frequency, do the Reference Oscillator calibration and 
check again.

Could it be that  many/most K3's are "slightly off frequency"?

[Elecraft] OT: FS Raspberry Zero W and accessories

2017-04-09 Thread Mike Markowski
I bought a Raspberry Pi Zero W a few days ago for a project and then 
realized I need a Raspberry Pi 3.  I can return the purchase but since 
the Zero W's are tough to find and often out of stock, thought I'd offer 
up the set here if any are interested.  I'm selling as a set for exactly 
the price I paid.  I bought them last week and they have not been 
removed from bags/boxes.  Luckily I read more on the project before 
doing that.  If only I read that much -before- purchasing!  :-)


Raspberry Pi Zero W: $10.60
Mini-HDMI / HDMI cable [QVS]: $26.49
USB 3.0 hub + SD card reader + OTG adapter [inland iH3048A]: $15.80
USPS Priority Shipping: $7.15

You pay: $60.00

Thanks!

Re: [Elecraft] New KX2 firmware with 4 programmable functions; need testers

2017-04-09 Thread Irma & Linas(LY2H)
Good news and thanks!
Looking fwd for this great improvement to be download-redy for the rest of
us.
I am a new (up to 2 months) KX2 user so the first things I found myself
missing is more Pfn buttons, at least 2. Now there going to be 4 of them!
So my first set would be PF1 =VOX, PF2= XIT, PF3=BKLIGHT, PF4=PS. Using the
radio car mobile a lot I already use the existing Pfn for the VOX in CW
mode, and the XIT is the second mostly needed. I will finaly decide on the
last two after some more time of variety usage.

Re: [Elecraft] Future KX3/KX2 accessories?

2017-04-09 Thread Charles Plunk
Sorry for the late replay. My bride had quadruple bypass on 3/20. I 
don't know if this would be considered an accessory, but really would 
like to see the clock/date be able to retain memory so would not have to 
set it every time. KX2 really is a great radio though, just about 
everything I thought it would be and more.


Staying with her during her recovery when not working but looking 
forward to her full recovery and my qrp KX2 outings to resume ;-). I 
hope she will be going with me more often to get out and do hikes/walks. 
I like the KX2 so well that if I can ever get the power co. to fix the 
line noise near the house, may very well get a 2nd KX2 for the house.

I have an AH-4 that I have been considering interfacing with my K3s.  This
website has lots of good information regarding the signalling to/from it:

I have used my AH-4 pretty hard for 8-years (with an IC-7000).  It seems to

[Elecraft] New KX2 firmware with 4 programmable functions; need testers

2017-04-09 Thread Chuck Guenther

Beta firmware v. 2.75 works very nicely, Wayne.  Thanks for this!

My choices for Pfn are:
PF1 = SUB on/off
PF2 = RF Gain
PF3 = AGC THR
PF4 = Amp Hrs

73,  Chuck Guenther  NI0C


Quote from Monday, April 3:

"Hi all,

The latest KX2 field-test firmware provides four programmable functions, 
PF1-PF4, accessed using the PFn switch. This feature was inspired by both the 
original KX2 field testers and responses to our recent question about additions 
to the KX line.

Having four programmable functions rather than one really helps. The KX2 has 
fewer switches than the KX3, making it a bit more dependent on the menu for 
often-used functions.

If you’d like to give this new release a try, let me know. (Which menu entries 
would you assign to PF1 through PF4?)

Re: [Elecraft] K3 slightly off frequency

2017-04-09 Thread brian
All true.  Note that the standard oscillator takes two hours to stop 
drifting instead of four.  Also the TCXO isn't.  There is no temperature 
feedback implemented.  One is essentially seeing the stability of the 
native oscillator.  Too bad feedback isn't implemented, I'd bet a lot of 
drift noted would disappear.


Not discussed is the "last digit" syndrome.  Only believe the last digit 
displayed if you can check that it is accurate.


With the standard synthesizers, as one tunes up the band the true 
frequency deviates from the displayed by up to +/-4 Hz.  There are times 
when one tunes up and the RX actually goes to a lower frequency.  Same 
problem when tuning downwards. In other words, there is electronic 
"backlash".  One has no way of knowing which point of this sawtooth 
error curve you are when choosing to calibrate to WWV.  This is 
essentially fixed with the new synthesizers.

My K3 has the new synths (2), K144XV with REF Lock option and all is

With respect to the post about off frequency, not a simple answer.

Firstly accuracy and resolution or precision are not to be confused, one
doesn't imply the other. The K3 display may read to 1Hz but that doesn't
mean it is accurate to 1Hz. If folks in a net all set their various
digital displays to the same frequency it doesn't mean they are all on
the same frequency.

As has been mentioned there is a perfectly good method of adjusting
calibration detailed in the handbook using WWV. It doesn't directly tune
or otherwise adjust the reference oscillator (TCXO) but lets whatever is
involved with controlling the synths what the reference frequency really
is so that the error can compensated for mathematically. That is my
understanding. I have been using this WWV method for the past nine years
and was convinced that the TXCO was probably drifting with age and have
often said that the CONFIG: REF CAL is not a one off adjustment. This
unfortunately turns out not to be the whole story.

Now it has to be said, the TXCO does drift, shock, horror. The high
stability option is described as being +/-1ppm but actually seems to
achieve 0.5ppm, at least mine does. How do I know this? I don't have a
frequency counter, or at least I didn't and in fact you don't need one
as will be discovered later. What I do have is the K3 external reference
frequency lock option fitted and recently purchased a Leo Bodnar GPS
disciplined reference clock which provides the necessary 10MHz drive for
the ext ref option. With a new toy you have go to play and what I
discovered follows.

With the GPS source up and running, turning on the K3 and enabling the
external ref feature the REF CAL measured TXCO frequency will be
displayed, counted by the ref lock module. This frequency will be seen
to change with warm up. My TXCO has a positive drift of approx 26Hz+/- a
couple in the first three minutes, for the next 30 minutes it drifts a
further 6Hz. Thereafter it slowly drifts until after four hours it tops
out at +57Hz or so and by this measurement method stops drifting.

However, there is more. At the same time as noting the REF CAL frequency
every minute, for the first hour, I also recorded the front panel (FP)
temperature. This started at 23C and over the measurement period
increased to 38C. It was observed that the rise in FP temp and the drift
follow a similar trajectory. As would be expected.

I have monitored the REF CAL frequency for a couple of months now and
note that the TXCO drift on my unit always maxes out at more or less the
same reading.

I have reached the conclusion that if at least two hours of warm up are
allowed and a WWV cal operation is then performed you will be in a
pretty good place with respect to total drift and subsequent overall
frequency (dial) accuracy.

It is easy to discover the pattern and extent of the drift of the TXCO
in your K3 without any external measuring equipment, external ref locks
or such.

1. From cold tune to a WWV frequency you will be able to receive
reliably for a few hours. Higher the better.
2. Wait 5 minutes or you will be chasing a moving target.
3. Perform a REF CAL and note the reading.
4. Perform a REF CAL every half hour, less if you feel like it and note
the readings.
5. Eventually the reading will really slow down and more or less stop
changing.
6. Choose a reading that indicates that the bulk of the drift has
happened, (1-2 hours)
7. Set REF CAL to that reading and sleep well. Good enough for HF.

Given the highest and lowest frequency readings a further experiment can
be performed to discover the consequences of the TXCO drift on dial
accuracy. It only takes a few minutes.

1. Set REF CALL to the lowest recorded frequency and tune the K3 to a
stable test frequency, I used my XG3, note the "dial"

external ref feature the REF CAL measured TXCO frequency will be 
displayed, counted by the ref lock module. This frequency will be seen 
to change with warm up. My TXCO has a positive drift of approx 26Hz+/- a 
couple in the first three minutes, for the next 30 minutes it drifts a 
further 6Hz. Thereafter it slowly drifts until after four hours it tops 
out at +57Hz or so and by this measurement method stops drifting.


However, there is more. At the same time as noting the REF CAL frequency 
every minute, for the first hour, I also recorded the front panel (FP) 
temperature. This started at 23C and over the measurement period 
increased to 38C. It was observed that the rise in FP temp and the drift 
follow a similar trajectory. As would be expected.


I have monitored the REF CAL frequency for a couple of months now and 
note that the TXCO drift on my unit always maxes out at more or less the 
same reading.


I have reached the conclusion that if at least two hours of warm up are 
allowed and a WWV cal operation is then performed you will be in a 
pretty good place with respect to total drift and subsequent overall 
frequency (dial) accuracy.


It is easy to discover the pattern and extent of the drift of the TXCO 
in your K3 without any external measuring equipment, external ref locks 
or such.


1. From cold tune to a WWV frequency you will be able to receive 
reliably for a few hours. Higher the better.

2. Wait 5 minutes or you will be chasing a moving target.
3. Perform a REF CAL and note the reading.
4. Perform a REF CAL every half hour, less if you feel like it and note 
the readings.
5. Eventually the reading will really slow down and more or less stop 
changing.
6. Choose a reading that indicates that the bulk of the drift has 
happened, (1-2 hours)

7. Set REF CAL to that reading and sleep well. Good enough for HF.

Given the highest and lowest frequency readings a further experiment can 
be performed to discover the consequences of the TXCO drift on dial 
accuracy. It only takes a few minutes.


1. Set REF CALL to the lowest recorded frequency and tune the K3 to a 
stable test frequency, I used my XG3, note the "dial" reading in fine 
frequency display, 3 digits after the decimal point. I used the CW auto 
spot feature to do the final tune.
2. Set REF CAL to the highest recorded frequency and retune the K3 as 
above noting the "dial" frequency.


The lowest to highest REF CAL frequency is the total TXCO drift in Hz. 
The lowest to highest "dial" frequency will indicate the consequence of 
that TXCO drift in Hz. You will be pleased to note that the two do not 
match. The K3 tuned frequency change is rather less than the TXCO drift.


Reset the REF CAL reading to that you previously chose to be your K3's 
sweat spot.


The above shows why I was wrong in relating the REF CAL frequency 
changes to TXCO ageing. In reality it all comes down to warm up time.


I hope this was worth the read.

Mike VP8NO

Re: [Elecraft] Icom Remote Antenna Tuner

2017-04-09 Thread Michael Walker
It is all automatic.  AM, RTTY or CW.  Any constant carrier mode.  It will
also tune on SSB voice if you wish, but that isn't the best.  The processor
does a frequency analysis and tunes accordingly.

It is well outlined here on SGC's web site.

http://www.sgcworld.com/SideAd06.html and
http://www.sgcworld.com/generalsmartFAQ.html

These are not hobby grade tuners like ham ones we use (Icom, Kenwood, Yaesu
or even LDG).  These are commercial and military grade tuners.

I have used 4 of them on and off over the years when I need a tuner.
However, today, I only use resonant antennas and eliminate the need for a
tuner.

I have 1 SGC259 as a spare in case I need it for an emergency.  It is on my
2nd antenna port on my flex radio at my remote base.
http://www.eham.net/reviews/detail/1509

There is an SGC user group you can join.  Most of the Marine guys use them
as well.

[Elecraft] KX3 macro for swapping VFOb control when working split.

2017-04-09 Thread OE6FEG / M0FEU
Hi,
does anybody have any advice for writing a macro that will allow VFOb to
be controlled with the main VFOa tuning dial when operating in split mode.
It gets a bit annoying having to continually tune with the small OFS/B knob,
and whilst swapping frequencies from A to B works, that too can be a
nuisance in certain situations. I have the programmers reference guide and
have been looking through it, but I do not recognise then commands that
allow you to reassign control of specific parameters (in this case the VFOb
TX frequency) to different buttons or encoders (in this case the main VFOa
rotary encoder). Any help or advice would be greatly appreciated.

Re: [Elecraft] K3 slightly off frequency

2017-04-09 Thread Don Wilhelm

Steve,

The K3 is not 'known' for being off frequency.
Turn to page 50 and do the Reference Oscillator calibration.  If you do 
not have a frequency counter that is accurate enough +/-1Hz or better at 
49 MHz, you should use Method 2.

Is the K3 known, in general, for being slightly off frequency?

You may want to also look at the SGC Tuners.  Far superior to the Icom.
You can just send it an low power AM signal and it will tune.

I have used them in cars and many temporary installations and they 'just

The Linux source for the KX2 utility could probably be compiled on a
