[Elecraft] [K3} [KX3] SSBT like CWT ?

[Erik Basilier]

Peter, yes, I am sure many have thought about this. For something so
relatively obvious, one has to wonder why it hasn't already been done.
Perhaps the rapid changes in typical contest speech makes it hard to get an
accurate enough fix on the spectrum, unless one asks the other party to say
a long "aah" or some such sound? Or maybe the computing speed of the
hardware is a practical obstacle for a given rig? Maybe it has already been
tried by several people, and they ran into some kind of obstacle? Does the
frequency around 85 Hz stay very constant for a given speaker, as he or she
produces a variety of sounds? 

 

73,

Erik K7TV

===

This is an algorithm I've contemplated writing many times.

 

Voice results from the vocal cords snapping together in the range around
85Hz.  The filter effect of the various cavities, throat, mouth and nasal
are quite high Q and filter the harmonic rich vocal chord excitation to
produce the voice.

 

If you watch an SSB signal on your PSK waterfall you'll clearly see the
harmonics of the vocal chords.

 

I think a DSP algorithm that calculates the location of the carrier based on
the separation between the vocal chords is a definite doable proposition.

 

It would give SSB the perfect clarity you seek.

 

Love to have a go at this (I do DSP).  Do you Elecraft guys want to have a
go or interested in using it if I do it ? (I could probably do it as a piece
of PC code that processes sound card input so you could evaluate it).

Doesn't feel like to be a difficult thing to do.

 

Cheers,

Peter VK4JD

Hi Erik,

It's R & D.  Anything could happen.

I agree it's obvious but so are many things we see around us that weren't
there a short time ago.

The fundamental (vocal cord vibration frequency) changes constantly but not
particularly fast (it is a mechanical thing we do with our muscles).  The
constant is the original carrier frequency.  The relationship between the
vocal cord harmonics have a computable relationship back to the original,

I do think it's doable.   I've done some work on speech compression that
gives me some level of confidence.

Cheers,
Peter

Re: [Elecraft] [K3} [KX3] SSBT like CWT ?

[Lyle Johnson]

Hello Peter!

An interesting algorithm for automatically tuning an SSB signal was 
described at length in the Jan 1999 issue of QEX.


73,

Lyle KK7P


This is an algorithm I've contemplated writing many times



At Field Day I have observed a number of operators operating SSB. I have
noticed that there is a great variation in skill when it comes to tuning the
RX to an SSB signal...

Re: [Elecraft] [K3} [KX3] SSBT like CWT ?

[Eduardo González]

Hello friends.
I have worked on algorithm about SSB auto-tune and is a reality. I
have tested code using PC simulation software (Matlab) and using
realtime coding using C language. Just now i have several students
implementing such algoritms on BeagleBoard xM, Raspberry-PI and
STM32F4 boards using external ADC and DAC (except Beagleboard xM, it
have ADC/DAC in-board)
Effectively, as said VK4JD using equidistant spectral components of
harmonics sounds (human  voice) is possible get mistuning (using
special version of Ceptrum or two cascade FFT), but great issue is
caused by fricative voices (T,X,P,G,K, etc) because algorithm require
using a audacious estimation algorithm (as histogram) requiring
additinal computational cost.

Several years ago, Robert Dick ("Tune SSB Automatically", Robert Dick,
QEX, January 1999, pp 9-18) worked succesfully autotunning, in fact
this work i used as start point.
I have a paper about it, but was written in Spanish, use a traductor
to get details: redalyc.uaemex.mx/pdf/707/70712302.pdf

Sorry, my english is horrorous

[Elecraft] K3 - RF Board - C238 - AGC change

[Andrew Catanzaro]

I did the mod shortly after it was described here.  The change in AGC behavior 
was not subtle.  Yes it improved copy in pileups when I was the DX.  I found it 
a bit difficult to cope with, though, because the changes in audio strength 
amongst the stations was more than my ears have an appetite for.  I had some 
trouble putting up with the loud signals challenging my ears by the time I had 
the volume up enough to discern the weak ones.  I believe subsequent firmware 
changes have obviated the need for this mod.  I plan on removing the extra cap. 
YMMV.  This is only my experience and my observations.

73,

Andy

A year or so ago there was discussion about adding additional caps to C238
to reduce IMD. I believe it was two 1-uf caps.

What was the outcome of that? Did it make a noticeable difference in pileups
or for weak signal detection?

Is it a recommended mod?

Re: [Elecraft] [K3} [KX3] SSBT like CWT ?

[C L Jonkers]

The P3's waterfall itself is an excellent visual  tuning aid for getting very 
close to the the ideal frequency.  Followed up with QRN filtering techniques, 
tuning for best reception is easy. The K3 - P3 is a great combination.

Now,  if the P3 was a touch screen (ala iPad) and all the K3 functions enabled 
on it .. oh boy.

Re: [Elecraft] [K3} [KX3] SSBT like CWT ?

[Ron D'Eau Claire]

If you have trouble deciding whether you are tuned dead on, switch
sidebands. The pitch of the voice should remain exactly the same. If not,
you were off frequency. 

Doing it automatically sounds like an interesting challenge for a DSP
programming enthusiast, but hardly necessary for good SSB reception.

You a fee you can remote into a number of sites to operate remotely.

They will send you on a lease an K3/0 (hence the elecraft connection).

But the cost is really high 


I thought I shoot this out. I am not planning to subscribe and have no

[Elecraft] Info on front panel LEDs

[Dale Huffington]

Hi - my first message, so please advise if I should address my help
request to someone else.  I was moving up the bands to look for sounds
of activity, and when I hit 18 mHz there was a "pop" from the rear and
the panel lights went out.

Receive and transmit functions seem ok for CW.  I haven't tried sideband yet.

I have not found anything in the instruction manual concerning turning
the Panel LEDs on or off.

The lights come on when the power first comes on, but when boot-up is
complete, the lamps go out. I suspect I pushed two buttons
inadvertently ("band" and "menu" perhaps?

Any suggestions will be much appreciated.

[Elecraft] RX ANT PORT

[Al Lorona]

This is a message I prepared a while ago but never sent. Now that Mike K4PI has 
brought up the subject I thought this might be of interest without increasing 
the traffic too much.
 
We don't often pay attention to SWR in a receiving situation. If you have an 
antenna analyzer you can measure the SWR looking into your receiver; I measured 
the SWR of my receiver input as 1.5 (best case) and 2.1 (worst case) in the 40 
meter band. This may surprise some of you, but I have found these to be very 
typical numbers for ham receivers.
 
That's looking into the receiver. Looking the other way, into the antenna -- or 
in my case the antenna tuner-- I find that the best SWR I can reliably get by 
adjusting the tuner is 1.05.
 
This is a classic mismatch situation. Two 'blocks'--  in this case the receiver 
input and the antenna tuner input-- that are not perfect 50 ohm impedances are 
connected together. There will be reflections between the two stages that cause 
'mismatch loss'. Mismatch loss is the loss of signal due to imperfect 
terminations.

It is easy to calculate how much loss mismatches in a system will cause. The 
equations are not difficult [ http://en.wikipedia.org/wiki/Mismatch_loss ] but 
I 
use my Hewlett-Packard Mismatch Calculator (which is two sliding pieces of 
cardboard: old school, pre-smart phone apps!) In the example above, between the 
2.1 and 1.05 SWRs, it turns out that the loss is about 0.8 dB. This means that 
the signal-to-noise ratio of the signal you're receiving will degrade by 0.8 dB.
 
Let's let the receiver get worse; let's say that it is a 2.5-to-1 mismatch, 
which means that its input impedance is 125 (or 20) rather than 50 ohms. In 
this 
case, the mismatch loss becomes 1.2 dB which in the vast majority of situations 
is undetectable.
 
Now imagine that our receiver is particularly good and has an input SWR of 1.5 
to 1. The mismatch loss is only 0.28 dB worst case, which is pretty much 
unhearable.
 
You may be asking, "What if the antenna match is worse than the 1.05-to-1 used 
in this example?", and that's a great question. In the case where the 
antenna match increases to 1.5-to-1 and the receiver is also 1.5-to-1 the 
mismatch loss is definitely worse, but still less than 0.9 dB worst case.
 
In most cases for the typical mismatches found in our HF systems a good 
rule-of-thumb is to assume the receive mismatch losses are on the order of 1 dB.
 
Nothing in electronics is perfect, but fortunately when it comes to the 
imperfect input impedances of our receivers, we don't pay too high a price for 
the imperfection.

Re: [Elecraft] P3 rubber button

[Eric Swartz - WA6HHQ, Elecraft]

That was not a correct price. He must have thought you were requesting 
something else. The rubber keypad is certainly much, much lower in price.


Note that removal of the old keypad and installation of the new one 
involves making sure all of the adhesive from the original keypad is 
removed from the pcb, and that the button surface contacts on the PC 
board are clean and free from contaminants, hand oils etc. We usually 
recommend this is done at the factory.


Please email howard(at)elecraft.com for the P3 keypad cost. I'll make 
sure I talk to him about this first.

I would like to see the index,
it looks like a good idea.
but neither of the two computers give me a good idea of what it looks like.
When I try to download the high def PDF it does not show up.
I like the idea of the high def PDF by the way.
If there is some one who can forward to me the high def PDF
I would very much appreciate it.

[Elecraft] KXAT3 Internal Antenna Tuner Question

[Fred Carvalho]

Is there any documentation on ATU which explains how it stores antenna
matching parameters in its memory, if it ever does ?
It seems to me that after actioning on the ATU and getting a good match on
a given frequency, when I get back to it again, after tuning on some other
bands, using the same antenna, it losts the antenna info and needs to be
re-tuned. Is it how it works ?

Thanks Fred

Re: [Elecraft] KXAT3 Internal Antenna Tuner Question

[Don Wilhelm]

Fred,

The KXAT3 does remember the setting on each band segment.  I cannot 
recall the width of the band segments, but I suggest you do a TUNE on 
the bottom of each band, then move up 20 kHz and do a TUNE again.
When you go back to that same band segment, the tuning combination 
should be recalled automatically with no additional operations on your part.
If you do a TUNE again (at that point in time) the KXAT3 will initiate a 
new tune cycle and throw away the previously remembered values.  In 
other words, do not do an additional TUNE unless you change antennas.

I forgot to add - when initiallly setting up the band segments - 
continue the TUNE cycles until you reach the top of the band.

After that, all is automatic when you return to that band segment.

Re: [Elecraft] KXAT3 Internal Antenna Tuner Question

[Matthew Zilmer]

Don, I have a related question.  

A lot of my HF operations are Navy-Marine Corps MARS.  All of our allocated 
frequencies are outside the ham bands, and many are not even close to a band 
edge.  How does the K3 remember ATU settings outside the bands, or does it even 
have logic to support this?  I generally run the ATU when tuning to another 
MARS frequency far outside the bands.

Yes, I have the KBPF3 gen purpose filter, and everything is working fine 
outside the ham bands.

Re: [Elecraft] KXAT3 Internal Antenna Tuner Question

[Don Wilhelm]

Matt,

I really don't have a definitive answer, but I would think it would 
behave similarly.

Wayne may have a better answer or at least a pointer.

I do know you can manually set the ATU inductance and capacitance which 
works in places where you cannot transmit, but I don't know about 
automatic.
Of course, if TUNE works, then it works (it should), but I don't know 
about the memories.

If it's an SSB signal, and I switch sidebands, won't I be trying to listen

Your advice sounds appropriate for an AM using an SSB receiver or Double

Matt --

That's something that I've wondered myself, for similar reasons.

I have noticed that the MARS frequencies closest to the amateur bands (e.g.
low 4MHz) are remembered by the KAT3, while those further outside (e.g.
high 4MHz) are not.

At this point, I know by experience which of the frequencies I regularly
use do/don't need to tuned up.   But for those times when I might need to
use other frequencies it could be handy information to have.

Re: [Elecraft] KXAT3 Internal Antenna Tuner Question

[WM3M]

Not sure I completely follow this since I think the KXAT3 is the tuner for 
the KX3, but questions seem to apply to K3.
I have both K3 and KX3 and use both on MARS freqs.  The KXAT3 in the KX3 
does remember the settings for all the MARS freqs I use.
I do not have the internal tuner for the K3 but do have the KAT500, it also 
remembers the settings for all my MARS freqs.  The K3 will not transmit 
close to its IF freq, so I normally the KX3 for those.

Hope this helps?

Re: [Elecraft] KXBC3 behavior

[Peter Lambert]

Hello Fred,

I've seen a few oddities in the battery charger also.  I think some
variables that you change don't have immediate effect for some reason I've
not bothered to investigate.

Try setting the charging parameters you want, then exit the menus and turn
the KX3 off with the 2 button salute.  Then turn it back on and start the
charge cycle.

Hi Rich

Thanks input. When it stopped charging, it is very unlikely that batteries
reached 45C. I felt no

abnormal temperature. The case was as warm as it was one hour earlier.
As I said, no error message was

issued. The charging never resumed.

I have depleted the batteries and went thru a 16hours charging cycle.
Close to 12 hours latter,

same thing happened again. Charge stopped.

I have emailed the factory couple days ago and I am waiting their input on
it.

Regards  Fred PY2XB



Fred,

Most likely the battery temperature got up to 45 degrees C and charging was
suspended until they cooled to 40 C.  Normally a message should appearwhen
that happens.

Re: [Elecraft] KXAT3 Internal Antenna Tuner Question

[Matt Zilmer]

Hi Michael,

Well, for those close-in freqs, it's not been a problem here.  I was
thinking around 11 or 12 MHz where there isn't a ham band in sight for
a considerable span.

Re: [Elecraft] P3 rubber button

[Brenton Meadows]

And a great happy ending, many thanks to the team at elecraft...
Great price for the replacement part, this would be $200 from Motorola haha.

Members of the mailing group, Pls see part number below for your reference
if you ever need one.

Cheers
Brenton
VK5BM/3
Other callsigns VK3NV, VK3JC

Hello Brenton, yes here's the info that you need:

Here is the info on the P3 buttons. 10 buttons, all one piece. Should be
around $10.

10 button Molded key pad 1 E100349
and a 2nd answer

Brenton,

Here's the P3 button information you requested:

E100349 P3 Switch Array $10.36

Please note that removal of the old keypad and installation of the new one
involves making sure all of the adhesive from the original keypad is
removed from the pcb, and that the button surface contacts on the PC board
are clean and free from contaminants, hand oils etc. If you use acetone to
remove contaminants please be very careful that it does not get on or in
the LCD display.

You can order this part or any parts you might need from the Elecraft kits
directly on our secure credit card page
< http://www.elecraft.com/newcc.**html >
Just fill in the credit card information and in the "Comments" box describe
the parts you need including the Elecraft Part Numbers (found in the Parts
List of your Elecraft Manuals) and quantities.

Re: [Elecraft] KXAT3 Internal Antenna Tuner Question

[Michael Adams]

Matt --

I'm not even sure I'd call the lack of memory on the KAT3 on those far-out
frequencies a "problem".  For me, at least, it's curiosity and potentially
useful information in the future.

The only time the lack of memory has been inconvenient is when I've joined
SHARES nets in progress (and have to remember to go aside and tune first,
since SHARES tends to be further away from the amateur bands), or when
bouncing around during the Armed Forces Day test.

Re: [Elecraft] KX3 Backpack Recommendations

[k7nhb]

Bruce, Someone mentioned a "jellyroll" it is padded and used to hold a
photography lens. But at 4 inches in diameter and 9 inches long, it provides
a nice house for the KX3 - but not much else. If you search for "jellyroll
case" on Amazon you'll find two of them, one charcoal and one brown (camel).

I started out using Pelican cases but I've really found them too big and
heavy - overkill - for the packing I do. The gear does go in a waterproof
case, but though they are waterproof, they can't be run over by a truck like
a Pelican case can.

Paul K7NHB

[Elecraft] Price Increase this Friday - Finally

[Eric Swartz - WA6HHQ, Elecraft]

Advance notice for our Elecraft list members -

We will finally be making the price increases this Friday that we 
originally planned for last September. (We were so busy with the KX3 and 
other products that we kept putting it off until now - to everyone's 
benefit :-)


The web order form at http://www.elecraft.com/elecraft_prod_list.htm 
will be updated between 6 and 9 AM CA time (PST) this Friday, Feb. 8th. 
Orders placed before the order form price increases take effect this 
Friday will be honored at the current prices, even if we have the item 
on back order. Any customer requested delayed shipping on an order must 
occur within 30 days of the order date to hold the pre-increase pricing.


We're working hard to keep the changes reasonable and they pretty much 
just cover our increases in material costs.


Please -do not- call or email sales to ask for specifics on the 
increases or products effected before then.  We are still finalizing the 
needed changes, and the sales group does not have the information yet 
and will not be able to answer questions before Friday.

Re: [Elecraft] KX3 Backpack Recommendations

[david Moes]

Have a look at Lowepro backpacks. They have a huge selection of padded 
backpacks for photo.   I have a large one for all my camera gear  it 
even has a slot for a laptop.  its one of the larger padded backpacks 
with padded dividers.   I can rearrange the padded dividers and fit key, 
headset,  laptop and K3 in it. a smaller backpack would be excellent 
for a KX3 with room for batteries, key, wire antennas, mic and a key.  
with room for lunch and a few other essentials. some even have holders 
intended for tripods  or in this case perhaps a Budipole.
