Re: [Elecraft] K4 eHam Review Updated

[Andrew Faber via Elecraft]

 Rick, and Bob, Thanks for the reviews.  I note that Rick started his off with 
a clever limerick. Here's another limerick in honor of both reviews: The K4 has 
been a long wait,
There's been lots of talk and debate.
  But its finally here,
  And the verdict is clear;
Reviewers say:"It's really great!"

Re: [Elecraft] Elecraft contact- K3 power problem

[Andrew Faber via Elecraft]

I had a similar problem with our K3/Astron PS atP40L-P49Y.  Removing the power 
cable from the back of the Astron and sanding the wires ends lightly (though no 
corrosion could be seen) solved the problem.

Gordon, 


Have you verified that your power supply and DC power cable 
are delivering full voltage to your K3 when the K3 is set to deliver 
110 watts output? This is a frequent cause of low power output. 
Use the K3 internal voltmeter

Re: [Elecraft] Arecibo antenna collapses

[Andrew Faber via Elecraft]

This is certainly getting way off topic on the Elecraft reflector, but I can’t 
resist mentioning that I have visited the FAST telescope in Guizhou Province.  
Here is a brief explanation from my trip notes (we were guests because my wife 
is an astronomer with many Chinese colleagues).  It’s odd that they are 
creating a tourist destination, since normally such telescopes are located to 
minimize RFI.

“We were met by a driver from FAST in a Honda Odyssey for the two-hour drive to 
Pingtang, China’s self-proclaimed “Astronomy City.”  There is a huge amount of 
new construction, as they try to take advantage of the FAST to create a tourist 
destination. There are new shops and hotels being built, and on the sides of 
the roads they even have statues and bas reliefs of famous scientists and 
scientific instruments.  FAST stands for “Five hundred meter Aperture Spherical 
radio Telescope,” and that’s just what it is – outdoing the 300-meter radio 
telescope at Arecibo, Puerto Rico by far.  It’s in a valley that had a dozen or 
so homes before they houses were demolished.  It’s 500 meters across, and is 
partly steerable, since the panels can be somewhat deformed by 4,000 actuators 
pulling on cables that tug on the panels that comprise the reflective surface.  
The receiving “cabin” is suspended on cables attached to six huge (maybe 
350-400 feet tall) towers.  So by moving the cabin and pulling on cables, they 
can apparently track through about 20 degrees, unlike Arecibo, which is fixed 
in a spherical shape.  The actuators that deform the mirror into a parabola are 
hydraulic and need only pull about a foot and a half or so on each cable.  
Although it was late, we drove down for a quick look at the telescope, since it 
wasn’t raining.  It’s an unbelievably impressive mechanical construct.

Re: [Elecraft] OT (sort of, but they use all Elecraft gear): Baker Island

[Andrew Faber via Elecraft]

For one data point, when I got up for other reasons this morning at 2:20 
a.m., I turned on the radio, as I need KH1 on 160.  They were very solid 
copy on 1822.5, and easy to work, using my K3 and KPA500, with only an 
inverted vee for TX and RX.  I was surprised that they were solid copy, as 
that's not usually my experience on 160.

Re: [Elecraft] Linear thoughts

Eric,
Hallelujah!  First acknowledgment of such a possibility!  I vote to put a 
second amp module in the RF Deck (i.e., an RF deck that is the same as the 
total size of the KPA500) and have a separate switching supply in another 
box. 1200-1300 watts would be a sweet spot if 1.5K is a problem.  Shoot for

[Elecraft] KPA-500 fix

[Andrew Faber via Elecraft]

I thought I would share a fix to my KPA-500 with the group in case someone 
else might have the same problem.
I have an old amp (two-digit serial number), and it has performed flawlessly 
until yesterday. Suddenly the Operate-Standby button stopped working, and 
then I noticed that other buttons worked, but did strange things.  The cure 
was simply to take off the front panel and reseat the two ribbon connectors. 
Actually I could only reseat the large connector at the panel end, and the 
small one at the board it plugs into in the main body.  The other end of the 
large connector is at the back of the amp and not accessible without 
considerable disassembly.  And the panel end of the small connector was 
stuck on so tight that I was afraid I would break something in removal.  But 
reseating 2 of the 4 possible connectors did the trick.  Now it seems to be 
back to normal.

Re: [Elecraft] great article on AGC by Fred Cady

[Andrew Faber via Elecraft]

Ian,
At P49Y, I also like to use SLP=0 for pileups, because then one can "ride" 
the RF Gain control to try to differentiate signals within a pileup. On the 
other hand, for casual operation, it is easier on your ears to use higher 
values of SLP in order to make the volume of signals more constant.  This 
also works better in a contest for the second radio if it is used for S on 
another band.

Hi Ian,

Most of my operating has been contesting and dealing with pileups.  I want 
to have the most discrimination or differences between different strength 
signals in the pile up.  And it would also like the radio to be as linear as 
possible.  So I would normally use a high threshold and SLP=0 (oddly, that 
is the steepest slope) so that loud signals sound loud and weak signals 
weak.  On the other hand, for rag chewing in a you might want all signals to 
sound pretty much alike.  Then choosing a low thr and slope=15 will flatten 
out the signals.



Don has some great ideas on setting AGC in his article, especially regarding 
noise.  It is easy to hear (and see) if  you have the THR set too low and 
noise is activating the AGC.  Tune to a noisy band and then start cranking 
THR down.  When you get too low you can easily hear the noise level 
decrease.  If you set up the dBV measurement you can actually measure the 
reduction in audio level.

There is an asterisk that appears on the left side of the KPA500 display

Re: [Elecraft] K3 Power Changes When Driving My Amplifier

[Andrew Faber]

Yes, this is a very helpful menu item.  I normally keep TUN PWR set at 20 
watts, which allows amp tuneup to be started at lower power with less 
likelihood of damage due to a switching or antenna mistake.

Re: [Elecraft] Relay boards for remote control?

[Andrew Faber]

Another source is http://www.j-works.com/index.php. They have a broad 
product line. I've used one of their devices (USB to 4 SPST relays) for 
years with my logging program CQPWIN, instead of using serial or parallel 
port outputs for various rig control functions (e.g., PTT, Radio switching, 
etc.).  Never had a problem.

There are others. I use a SERDO8R purchased from EasyDAQ.com. It has an
RS232 interface and eight DPDT relays on a PC104 stackable profile. Current
price is $81, which I think is a bit much, but it is a well-constructed
board and is supported by National Instruments LabVIEW drivers (which I why
I have it). For $97 you can order it with eight programmable digital inputs
or outputs that operate in parallel with the eight relays.

I think Denkovi has a broader range of products with more interfaces and
lower prices. If I needed another relay interface I would buy the Denkovi
USB Eight Channel Relay Board ForAutomation, currently selling for $41, but
I have no experience with them.

Re: [Elecraft] Need information

Dick,
 I've had a K3 for over 5 years, and a 7600 for a few months (but before 
that a 756 Pro2 for years).  What specific questions do you have?  They 
should be very similar in CW reception, though the K3 would have an edge in 
very crowded (e.g., contest) conditions.

Hi All,

I am new to this list.  I do not at present have a K3, although I did build 
a kit several years ago.  Shortly after I built it I had to sell it. I did 
not use CW at that time.


I acquired an Icom 7600 which I still have. I have become addicted to CW 
lately.  If  you go to my QRZ page  you will see t he antenna that I have to 
use here at the retirement center where we live. I  have been using mostly 
PSK until lately and I can reach into Canada and down into Mexico (a far cry 
from the 50 foot tower I sued to have).  But it wlrks and keeps me 
interested.


My question is:  Is there anyone that used to  have a 7600 and now has a K3? 
How do they compare? I am having a problem with reception of CW.  It could 
be the antenna, but I am noticing  when I try to use reverse beacons that I 
don't get any hits.  I am TX  at about 50 watts.  Any ideas?


Thanks in advance. The more that I read about the K3 the better I like it.

Dick, N5XRD

Re: [Elecraft] K3/KX3 Operating Tip: APF (audio peaking filter) forweak-signal CW work

[Andrew Faber]

Wayne,
I was pleased to see the APF added to the K3, though I think it is not as 
useful on radios with such good basic filtering, as compared to older 
radios.  OTOH: it's a favorite feature of my old FT1000D!

Subject: [Elecraft] K3/KX3 Operating Tip: APF (audio peaking filter) 
forweak-signal CW work

Both the K3 and KX3 have an APF control (audio peaking filter). APF
can be extremely effective when you're trying to copy weak CW signals
buried in noise.

Most DSP filters have very steep skirts; they're often referred to as
brick-wall filters for this reason. This is the type of filtering
associated with the WIDTH control (K3) or PBT control (KX3).

In contrast, the APF is a filter with a very narrow peak (about 30 Hz
at the -3 dB points) and very broad skirts. The narrow peak brings up
the signal amplitude slightly, while the broad skirts prevent noise
from being amplified and delayed in such a way as to dominate the
signal. The APF function used in the K3 and KX3 is a modern DSP
reinterpretation of the hardware APF circuit found on some legacy
transceivers, which was very effective.

On the KX3, the APF switch is labeled APF (tap), while on the K3,
it's labeled DUAL PB (hold). The K3 actually provides two different
special filter functions; use the DUAL PB menu entry to set up the
switch for APF.

When you turn on APF, the DSP graphic changes to remind you of the
nature of APF, with its narrow peak and broad skirts.

I suggest setting the passband width to about 250-300 Hz when using
APF. The DSP graphic still shows an approximate representation of the
width even with APF turned on.

73,
Wayne

Hi All,
Just a short note for all regarding Fred Cady's fine K3 book which very 
nicely augments the K3 manual.   I just ordered another copy for a UK based 
friend and with shipping this book cost just €24.38.  The shipping costs by 
priority mail are only €3.46 which for a 288 page tomb is not bad at all. 
There is no VAT on books in the Land of Saints and Scholars so I do not have 
to cope with this added expense.   Normally the delivery is two or three 
weeks to EU and I think my first copy arrived within less than ten days. 
The book is informative, good value and the shipping is not dear at least 
for EI and G.

  Remember the discount code:  GIANTSHAMROCK.   I believe you need to 
use this before 12 PM today March 15; they should have kept the offer open 
till the end of the 17th.

  Happy St. Patrick's day to all.

Re: [Elecraft] Activate voice memories by computer

[Andrew Faber]

Alan,
  It's easy to activate the voice memories simply by sending a macro to tap 
the appropriate button.  It's a bit more complicated to measure the length 
of the message, if you want to set up an auto-repeat function, but that can 
also be done.  I do that in my program, CQPWIN, and also insert a variable 
delay (I usually use about half a second) to account for the fact that there 
is usually a delay from the pressing of the button to the start of the 
recorded message (depending on exactly how you record them).

Hi Allen,

You need to ask K4HAV if his software can sent commands to the rig
when you invoke hot keys. If it can, you could use the same approach
as I have documented for N1MM Logger. If not, other solutions may be
possible, but would require some engineering - e.g. an additional
program that can generate the commands, linked-to with autohotkey,
and LP-Bridge to share access to the K3.

Not real sure what you question is, but

If using n1mm logging software, it is possible to have n1mm send
message to the K3 to play one of the m1-m4 memories pre-recorded via the
DVR for call and/or contest exchange.  Works very well.

Re: [Elecraft] Flying with a rig

Mike,
  I carry my K3 in a backpack from SFO to MIA a few times a year on the way 
to Aruba.  I leave it in the backpack at TSA.  The last two times there were 
no issues at all.  Occasionally in the past they have asked me to remove it. 
They have then checked it for explosives with some kind of swab and run it 
through the scanner again, but have never asked any questions, or required 
that it be turned on (which I can't do, since I don't carry a PS). So I 
wouldn't expect any major problems at all. I always have a copy of my US and 
Aruban ham licenses with me, but have never had to show them to anyone.
  On the way back, in Aruba, I've never had any questions asked at all.

Gary, I have found that the best way to quiet the K3 is not via the audio
settings, but by simply backing off the RF gain about 60 - 90 degrees from
max. This just about always improves the perceived s/n ratio. When I first
got my K3 I was a little frustrated because my beloved but outdated MkV
sounded a lot better to my ears, but a simple twist of the RF control put
everything right. I have tried A/B with the K3 versus a few other
receivers, and it is tops as far as I can tell. I think the only rx in its
class is the FTDX5K, but there's probably no discernible performance
difference, just a matter of 35 pounds and 2500 bucks.

I had a P3, which I liked a lot, and now have LP-Pan plus NaP3 for a
bandscope. That combo plus a K3 plus a KPA500 makes for a compact,
multi-talented, elegant ham setup.

Re: [Elecraft] Best setup for DX pedition K3

[Andrew Faber]

Jim,
  At P49Y, I have found it useful on CW to use an AGC slope setting that 
reduces agc compression.That way you can use the RF gain control to help 
manage the pileup. But I recommend keeping the AGC on so that you don't get 
blasted by a very strong signal after you have been straining to pull out a 
weak one with the af gain turned up.

I am looking for suggestion on the best receiver setup for our trip to

reading about the VP6DX guys probably using no AGC and riding the RF
gain if my memory is correct.

Are there any other tweaks that might come in handy?

1. What Input SWR are you seeing? Does it vary by band?

2. Is there a lag in band switching when not using a K3 (Used with
non-Elecraft radio).

3. In normal SSB operation, how loud is the fan? I know this varies
per person, some don't hear fan noise and others do. What would you
compare it to? As an example, the Yaesu MARK-V Field is OK, but the
MARK-V 200 watt model is too loud for me.

Re: [Elecraft] KPA500 - KPA-500 and the KPAK3AUX Cable - lessons learned

[Andrew Faber]

Pete,
  In my experience, a standard extension cable does work, provided all 15 
pins are connected through. Cables marketed as VGA extender cables, however, 
often don't have all 15 pins connected.
  The Elecraft cable doesn't either, but they are a different set.  Using a 
normal extension cable with all pins connected does have the consequence 
that the KPA turns on automatically when the K3 turns on, but then cannot be 
turned off with the front panel switch unless the K3 is turned off.  That 
may or may not be thought of as desirable behavior.

If you like, I can make you up some professionally made, Molded Double 
Shielded (braid  foil) Dual Ferrite cables of almost ANY common (3', 6', 
10' 25' etc) length to suite your shack configuration.  If you've already 
resolved the problem, and are happy with where your equipment is placed, 
than I will be happy to extend (no pun intended) the opportunity to anyone

I know the instructions for the KPA-500 say not to use a standard SVGA
cable.  The special KPAK3AUX cable is the way to go.  But that cable is too
short for the arrangement I had for my station so I thought I could use a
standard SVGA expansion cable (female connector on one end, male on the
other).
What I didn't fully digest is that the wiring is incompatible!  I thought
the difference was merely the removal of a few pins from a standard SVGA
cable.
Nope, that doesn't work!  So if your station requires a longer cable than
the KPAK3AUX you can either purchase two cables and put them in series or
you can make up your own.  Don't use a standard SVGA cable at all.
In my case, I just rearranged the equipment.

Although you probably won't have big pileups on FD, I'll pass along again 
the settings that I have found effective at P49Y in CW contests.  AGC-S, AGC 
SLP=6, AGL THR=6, allow using the rf gain control to help manage pileups, 
without losing the benefits of AGC in protecting you from really strong

Re: [Elecraft] Fw: KPA500 kit

[Andrew Faber]

Dave,
  I think that actually may not be the intended behavior.  I used a 15-pin 
extender cable (non-Elecraft), and one of the pins in the AUX output is a 
PWR ON output from the K3.  I have heard that Elecraft actually cuts this 
pin in their interconnect cable, because the PWR ON  features of the K3 and 
the KPA500 don't actually correspond properly (the KPA's is is a toggle, 
while the K3's is a high or low state).  The result is that with my cable, 
the K3 will turn on the KPA500, but won't turn it off.  Furthermore, while 
the K3 is on, the front panel ON button on the KPA500 won't turn it off 
either.  So it may be better not to have this feature at all.
  I found non-Elecraft cables are quite inconsistent as to what they 
actually consist of.  Many are VGA extender cables, which actually don't use 
all 15 pins.  In addition, I have some such cables that apparently ground 
the K3 PTT input line, with the result that you can't turn the radio off 
while the cable is connected!

Re: [Elecraft] P3 on DXpeditions (was P3 and SSTV)

John,
  Thanks for sharing your experiences.  Sounds like a great trip.
  While not exactly dxpeditioning, I take my P3 to P4 for contests, and find 
it to be invaluable, both for checking band activity and for finding open 
spots for running.  Here's a picture of a prototype P3 in use in 2010 WPX CW 
a year ago:  http://arubaqth.com/Images/2010_large/2010_May_432_750.jpg
   Suggestion to Elecraft:   What would make the P3 even more useful for 
travelling would be a smaller version.  The box is mostly empty space, so a 
faceplate in a 2-3 inch deep box with appropriate fold out feet or braces 
(perhaps hinged to the back of the case) to allow the buttons to be pushed 
would be much easier to transport.

I have also been one of those who has bugged Wayne about what I thought was
 a less than adequate operating manual for the K3 (not realizing, of

 that he was the author).

 Speaking as an EE who has been a ham for more than 50 years, my background
 is systems integration in the aerospace industry and try as I might, I
 cannot keep up with the kind of technology that is contained within the
 chassis of the K3.  The manual has been written at too high a level for 
 me.
 It is adequate for me to operate the K3 as an appliance but I yearn for
 something with a bit more technical and operating detail than that.

 Wayne's response was something to the effect that perhaps someone would
 volunteer from the user's group to lead a project to add the necessary
 detail.  Given the unreasonable level of effort that Elecraft would have 
 to
 contribute to make us all happy with their documentation and given the
 awesome amount of talent represented by the K3 user community, that seemed
 to me to be a reasonable thought.

 That would represent a huge effort but the subject matter experts are all
 here and the technical writers are all here and I look at any perceived
 shortcomings in Elecraft documentation as an opportunity for all of us 
 proud
 K3 owners and Elecraft supporters to give the company back a little
 something in return for what they have done for us.

 Wouldn't it be a wonderful thing if someone stepped up to project-manage a
 supplemental re-write of the K3 documentation!  Handled properly, it need
 not reflect negatively on Elecraft and I would have to guess that it would
 represent a first within the amateur radio community.

Re: [Elecraft] An AGC story

[Andrew Faber]

I have no doubt that AGC adjustments are largely a matter of personal 
preference, and I congratulate Elecraft on making the K3 as adjustable as it 
is without overwhelming us with so many variations that we'd go crazy trying 
to figure it out.
 As an example of individual adjustments, I used the K3 as my run radio in 
CQWW CW  from P49Y in 2009.  Because I wanted help thinning out the pileup, 
I found that setting the SLP to 1, but leaving the AGC on worked well, and 
allowed me to ride the RF gain control to help distinguish signals while 
still offering some AGC protection against very strong signals.
  OTOH, in this years CQWW CW, where I was just doing some SP DXing from my 
home station, I set the SLP to 6,  to allow me to turn the gain up higher to 
detect weak signals while still having protection against very strong ones. 
Using SLP 1 in that scenario with the RF gain all the way up was just too 
close to not having AGC at all.
  So I encourage everyone to experiment within the existing framework.

 But, since AGC works on every signal in the  passband, if there are
 two signals - one S9 and the other S3 appearing at the  same time,
 the S3 signal will disappear because the AGC is knocking down the
 S9  signal to an S3 level and thereby also reducing the S3 signal to
 the  noise.

 My impression from reading what has transpired is that some people are
 more concerned that when the S9 signal is *not* there, that the S3
 appears to be too loud?

 We know that the S9+ signals have to be kept from saturating the A/D
 converter (or even kept in check so the large signal doesn't do
 naughty things to the IF amplifier and the SA612 second mixer -- I
 don't know which of these three is the wimpiest in the chain).  So
 some AGC is neccessary.

 Perhaps people will be happier if the AGC response is not as linear
 (in the log-log scale) as the one in the K3 once you have past the AGC
 threshold.  I.e., perhaps people would care less if an S7 signal sound
 as loud as an S9 signal, but they do want the S3 signal to sound less
 loud as the S7 signal.  A non-linear transfer function like that is
 certainly easy to implement (as long as I don't have to be the one
 to implement it :-), but will this make more people happy?  Who knows?

 Basically, this is what I am simple-mindedly visualizing: currently,
 there are only two parameters to control a piecewise linear curve.

 Imagine that there are three parameters, the current two, plus a
 upper threshold, after which the slope becomes 15  (i.e. flat at
 S0 to THR, then constant SLOPE until upper threshold and then flat
 from there until the front end starts to smoke),.  You then smooth out
 the piecewise linear curve using a pair of homotopy between those
 three partitions.  You will end up with (1) a smooth curve instead of
 the piecewise linear one currently, and (2) a way to say I care more
 about distinguishing an S3 from an S9 signal than I do an S7 and S9
 signal.

 Notice that if a simple homotopy is applied to smooth the AGC transfer
 function, and even if upper threshold is set to S7, you will still
 hear a difference between S7 and S9 -- just much less than between S3
 and S9.  Also, if the AGC curve is no longer piecewise linear you will
 still hear the S3 signal even if the lower threshold is set to an S3.

 I still think the only way to satisfy everybody is if everyone would
 homebrew their own rig, or sell an open commercial rig where you are
 allowed to make any mods -- hardware, firmware, or software.  See
 first option :-) :-).

  N1MM doesn't know anything about the DVK, it just sends the Mx tap

 this is true for most loggers.

Re: [Elecraft] The K3 at airports

Like Ed, I carry a K3 in a backpack to Aruba.  The last two times in SFO 
they have removed the K3 and run it through separately, but no problem (of

In Aruba, the TSA never seems to notice.
  My Begali paddle in the backpack also arouses suspicion at SFO, but again,

 clear but what got me was the quality and tone of her voice. It was very 
 easy to listen to. Good tone. Warm sounding with out being mushy. But as I 
 said, clear but not edgy at all.
 It seemed she had the perfect mike / eq / radio combo.
 Wonder what she was using?
 I have my K3 and K2 outputs driving a pair of Fostex alnico full range 
 speakers. The cabs are of a modest size but built with 3/4 plywood. It is 
 my belief that the alnico magnet is one of the reasons the tone in my 
 system is as good as it is. Today it is fairly rare to find alnico in 
 speakers. (expensive) it also helps to have speakers that are fairly 
 efficient... Over 90db per watt. With 96 db or better being a good target. 
 The more efficient the speaker the less work the amp has to do and 
 therefore lower distortion. I use simple pencil tube stereo homebuilt amp 
 to drive the Fostex speakers or headphones. Headphone are the AKG 701.
 Sometimes the ssb transmissions sound like good or even great AM 
 broadcast. Good tone for me is what it's all about.

 I have used both the K2 and K3 for some time, and as far as I can tell,
 there is nothing wrong in this department. There is more than enough
 gain to blast one out of the room or to fry one's ears using headphones,
 and the range depends in the normal way on the bandpass used in the
 receiver.

 Voice spectrum is scarce, and there is little excuse for using more of
 this resource than is necessary for effective communication. I think
 that almost all SSB operators realize the need and even the
 effectiveness and utility of band-limiting their TX. A quick look on the
 P3 or some other spectrum display will convince one of this. We should
 be thankful that people don't insist on transmitting the full range of
 audio frequencies that make up the human voice.

 Since what goes in dictates what comes out, it is unrealistic to hope

Re: [Elecraft] [K-3] RTTY for Dummies

[Andrew Faber]

Joe,
  An even simpler approach that doesn't even require a computer is to just 
use the text decode feature of the K3, which scrolls RTTY text on the VFO B 
display.  I made a number of search and pounce Qs this way in the contest. 
Memories with your callsign and the exchange can be recorded using a paddle 
plugged into the radio.  Although not elegant, it's then also possible to 
send RTTY from the paddle (if necessary) since the K3 automatically will 
convert the CW into RTTY.
  Someday I'll do RTTY properly, but this method suffices for casual help 
your friends out in the contest mode, hi.

 Tom,
I asked essentially the same question last week and received good info
 from the reflector.  After reading over 100 pages of AA5AU's excellent
 website and the MMTY pdf manual I still couldn't get things going.  I was
 still messing around with sound card settings and computer junk.  I 
 decided
 to again try the RTTY already built in the K3 and to further simplify I 
 used
 the K3 Utility program to get a bigger window for decoded text.  Here are
 the steps that worked for this Dummy:

 1. Turn on K3
 2. Launch K3 Utility and make sure it is talking to the K3
 3. Put K3 in Data mode (next mode down from CW)
 4. Press and hold the AFX key to enter Data Mode menu
 5. Turn Sub VFO knob until FSK D at 45 Baud is showing.  Press AFX key to
 exit this mode now.
 6. Turn on CWT so you have the tuning indicator showing.
 7. Tune SLOWLY so you have 2-3 bars on each side of the CWT gap.  I 
 listened
 to the audio as well to help me get a feel for tuning.  Once you have the
 tuning down you will be cooking with gas.

  You should now have RTTY printing on the K3 Utility screen.  You can use
 the memories to preload exchanges or just rag chew in the text window.  No
 additional 3.5mm cables etc. needed.

  I spent a couple hours each evening of the CQWW RTTY contest using this.
 I had 100 watts out through a wire antenna on 40 meters only.  I just
 wandered down the band each night and had 70 QSO's which accounted for 28
 countries (DXCC entities) on 40m.  Once I got going I wondered why I never
 worked RTTY before (been licensed since 1972).

  That's what worked for this Dummy, YMMV.

Re: [Elecraft] P3 suggestions

[Andrew Faber]

Al,
  Thanks for the reply.
  Regarding the reference level, the Icom always seems to simply set it 
correctly.  I assume it is not merely remembering the level when bands are 
switched, but is rather computing a new floor each time.  Is that a bad 
approach?  I like having the ability to adjust the reference level and the 
scale on the P3, but on the other hand, for a quick look at a band in a 
contest, it would be convenient not to have to make any adjustments when 
changing bands (even if the noise floor may have changed since you were last 
on that band).

 I've added a feature for the next beta release where you can assign

 As of version 00.31, the REF LVL is saved per band.  There is a bug in
 currently-released K3 firmware that prevents the P3 from getting
 upgraded band information in certain specific situations.  (I've seen it
 happen when bands are turned off in the K3 band map.)  It is fixed in
 current K3 beta firmware.

 3) The Pro has a hold feature that freezes the display to allow you to
 move the marker to a signal that may have disappeared.  I realize to some
 extent the waterfall display allows that also, but it would be nice to be

 On the list.

Re: [Elecraft] P3 and required options

[Andrew Faber]

Dick,
  Good idea, but I'm not sure it is necessary.  I used a prototype P3 in WPX 
CW in May at P49Y with my K3, serial 0076, which does not have the mod.  Now 
this was in a contest, and I wasn't particularly looking for the weakest 
signals, but it did seem to interface fine with the older K3, just using the 
IF output of the K3.
  BTW: I strongly recommend the P3.  Without it I felt blind with the K3. 
Here's what I said in my 3830 writeup about it:


The K3/P3 combo performed great.  The K3 is so good as a CW run radio with 
its excellent selectivity that you can feel that you are in a hole during 
a run with no idea of general signal levels prevalent on the band (unless 
you are saddled with someone's key clicks in the passband), but now with the 
P3, you can see the other signals and get a good picture of what's going on 
in the neighborhood.  Thanks to Wayne and Eric, the owners, to Brian, who 
built it, and most of all to Alan, N1AL, the P3 designer.  Great job guys! 
It's still a work in process; in fact, Alan even emailed me new firmware 
Friday that I saw in the dark on my iPhone, but had no way to download (and 
didn't want to mess with once the power returned).  But I have no doubt that 
it's going to be an essential accessory to all K3-owning contesters.

 You may wish to install the IF Output Gain modification,
 http://www.elecraft.com/K3/mods/IF_Output_Buffer_Gain_Mod_Rev_A.pdf. This
 mod has already been installed if your rig was built after about September
 2009.

 It isn't essential, but you'll probably want to do this if you have a P3.
 The mod replaces one resistor.

 You'll need to connect to the K3's IF output, provided by the KXV3 or 
 KXV3A
 Rx Antenna, IF out, and Transverter interface option.

 The KIO3 does not require any changes for the P3.

 You can install the KXV3A yourself, and the IF Output Gain modification is
 straightforward.  The SMD parts are quite small, and it's easy to lose 
 track
 of them.

 Of course you can send your radio in if you'd prefer to have the mod
 installed at the factory. It took me a few minutes with the SMD part, and
 you'll want some magnification.  But it's just one resistor, and you can 
 use
 the leaded resistor if you prefer. The upgrade kit includes both a leaded
 and SMD resistor.

This has never been a problem, other than causing a slight delay.  On Aruba,

can clear the RIT while transmitting, which is helpful.  The Pro2 allows you 
to adjust just about any RX parameter while transmitting, and I find that 
extremely useful. I've commented on this issue since first getting my K3 in 
2007.

 Even the FT-1000D would not let you change RX filters during XMT.

 Rob K6RB

 I agree, the K3 certainly does have more RX things locked while
 transmitting than my MP,  but the MP had some as well.

 I seem to recall that this is also true of other software defined
 radios like Flex, but others can comment on that.  All of the K3
 controls are effectively encoders, including the rf/af gain controls
 which divide off a standard voltage and are converted to digital
 before they are used for anything and must be processed to have
 effect.  In a completely analog radio, each pot is always connected to
 its own circuit.

 The shift/width/speed/cmp controls are encoders only and tell the CPU
 when they are being turned and which direction, They can only only
 have an effect when the CPU is paying attention to them.  There is no
 end of pot or physical range limits on them.  They do not retain their
 state like rf/af controls.  In order to be continuously responsive,
 the firmware program(s) would have to be constantly running a state
 function for each of them, even while creating the transmit envelope
 from digitized input.  This could be disproportionately more difficult
 code or disproportionately more use of processing resources. Using
 encoders allows multiple functions for each knob, which would not be
 possible with if they were pots.

 But someone from Elecraft would need to comment to the rationale of
 freezing a given RX setting during TX and whether any unfreezing is on
 the firmware-to-do list.

 I know they have gone through at least two phases of optimizing code
 for resource use.

 I have to be careful myself -- I tend to be irritated by anything that
 is different, and there is a LOT in a K3 different from an analog
 radio.  So far none of them are deal breakers, and me getting used to
 them has been the real issue.  I was still fussing a year later about
 my new FT1000MP.  But when it was all over, were it not for fixing the
 key clicks, the quite crushable front end, and all the IM crap it
 added to the ambient band noise, it would still be my favorite, just
 because matched INRAD 8 pole filters in both IF's for all modes and
 bandwidths really worked well for selectivity AND I was finally used
 to the menus and knobs and rarely had to look anything up in the
 manual.  My new rig angst isn't particular to the K3, it's just me.
 It's new anything angst.

 I hate changes, I hate surprises, yada, yada, but that's my problem.
 Were it not for four years non-contest operating with a K2, the K3
 analog-to-digital-disconnect change together with panel changes may
 have been a deal breaker with where-the-h*ll-are-the-band-buttons,
 etc. But I had already figured out I could hear way better on any band
 with my K2 than the MP, and my brain's anti-change barking dog was
 regularly whipped back into the corner for the privilege of hearing
 the EU 40m QRP-basement-noodle-antenna crowd on my K3, and realizing
 that the next layer was an apparently inexhaustible layer of Russians
 that points to some *RX* antenna work to get them.  So now I'm getting
 used to the K3, .

 Going to N1MM logger from the DOS-based TR logger was quite more
 irritating than any switching receivers. I was thrown in the deep end
 of the pool, do or die, at a multi-op station with all those other ops
 around me that switched years ago and were very helpful, but couldn't
 quite keep the smirk off their face

 It's quite annoying during a contest for example, where you could use
 that little time to make an adjustment eg. change bandwidth, turn on/off
 preamp etc. before the rig returns to RX.
 I've never ever seen this behavior on any other rig that I own.

 I don't use the program although I tried it a couple of times but the 
 symtoms
 you are experiencing seem typical of what happens when you install a 
 program
 under Vista or Win 7 in the Program Files folder and the program tries to
 store settings in a file in that folder. The new Windows versions don't
 allow programs to modify anything in Program Files unless installed in XP
 compatibility mode, one reason I'm sticking with XP, because many
 amateur-developed programs are not being updated or their developers don't
 understand the problem because they themselves are using XP. It's a bit 
 mean
 to get snarky about ham programmers who release a program free of charge 
 for
 others to use, just because it doesn't come up to professional satndards.

 I have always installed my ham radio software in a folder called C:\Ham,
 which has the fortuitous benefit of falling outside Windows restrictions 
 on
 keeping configuration files in the same folder. Try that with K3_EZ, it
 might help.

Re: [Elecraft] [K3] IF output

You can also try borrowing an Icom Pro series (or presumably their larger 
radios as well), and hook the if out to the antenna input on the Pro, which 
will then act as a bandscope for the K3 when tuned to 8215 kHz..  I do this

 You should hear whatever signals the K3 is tuned to.  I'm assuming you

 If you haven't done the IF output mod:
 http://www.elecraft.com/K3/mods/IF_Output_Buffer_Gain_Mod_Rev_A.pdf
 then the signal level will be lower than at the K3 antenna connector.
 But with the K3 preamp on, the difference is small.  If you can clearly

 Gang,
 Thanks for all the great e-mails and answers to my first round of K3 
 questions.  Lots of good information and advice.  I do have a few more 
 questions but I will limit these of one question at a time.
 Several people have advised to get the sub-receiver option.  Now, this 
 really puts me on the fence as I have a sub-receiver in my Icom Pro III 
 and I almost never use it.  Actually, I have never used it in an actual 
 QSO, I have merely played with it from time to time.
 So, my first question is, Why do I want a sub-receiver?...
 Maybe a little about my background helps.  I got into ham radio as a 
 novice (WN7ECQ) back in the mid-1960s.  Ham radio was very rudimentary 
 back then with CW mode only, a transmitter and a few crystals, but a 
 very good receiver (Hammarlund, HQ-170AC).  Then, after the Novice 
 one-year license expired I let the hobby go silent for 38 years.  I was 
 relicensed and back on the air in February/March 2004 with a used Icom 
 756 transceiver.
 But, my operating style reflects a lot of my Novice experience rooted in 
 the technology and practices of the 1960s.  Mostly CW, some SSB for some 
 of the evening nets and other stuff when the band is hot and a 
 periodically scheduled SSB QSO with some of my ham friends from back in 
 those 1960 days.  Not much of a contester but I very much like the 
 technology aspect, experimentation, SDR, and so on.  And, I am always 
 looking to do new things that capture my interest.
 So, I may be missing out on a huge corner of this hobby by not even 
 knowing how someone makes use of a sub-receiver.  Thus, my question.
 73,
 phil, K7PEH

 Phil,

 My operating sounds somewhat like yours.  Mostly casual ragchewing, 
 piddling around in contests, but not seriously.  I had a subreceiver in 
 my previous transceiver, but decided to save the money when I ordered the 
 K3.  I don't miss it at all.  I am able to work split without it on the 
 few occasions I need it.  The beauty of the modular system is that if you 
 decide you need it, you can always add it later.

 73,

 Dave, W8OV

Re: [Elecraft] contest

[Andrew Faber]

Dave's suggestions are good ones, but having used a K3 for over 6,000 Qs in 
ARRL Phone from P49Y, I can say that they only go so far.  You will still 
get splatter from close stations.  The K3 is excellent at not creating 
digital artifacts due to nearby signals, but unfortunately a lot of the 
splatter you hear from nearby stations in a phone contest really is in your 
radio passband, and can't be eliminated by any setting of the controls on a 
K3 or any other radio.
 Note, it's also possible to run the DSP at a width as narrow a 1.6 kHz or 
so in extreme circumstances. Also consider backing off the RF gain at times.

Re: [Elecraft] K3 - KDVR

[Andrew Faber]

As an example of use of the K3 DVR, in March I was operating ARRL Phone 
froom P49Y.  When operating split on 40m you have to change your listening 
frequency every so often.  Although I generally use prerecorded messages for 
CQs, in that case it was easy to just record a new message in M1 on the K3 
announcing the updated listening frequency, then send it from the keyboard. 
Having the K3 DVR was very useful in that context.  Also, if you are ever 
having computer audio issues, perhaps due to rf pickup, sending the messages 
directly from the radio does bypass all those problems.  So I think it's a 
good fall-back option.

 I've done all that as well (or at least most of it), but it takes a
 moderate amount of time for me to check and edit the recorded audio
 files to make sure they sound as close to my normally transmitted voice
 as possible (same volume, etc).  I've heard some truly horrible examples
 during contests where the voice file and the real-time voice sounded so
 different that you'd swear it was a different person.  I even had one
 contact with a station where the recorded voice was from a man and the
 operator was a YL!  Any confusion that sort of thing causes just slows
 the QSO rate.

 I don't own a KDVR (yet), but one of its potential advantages would seem
 to be the ability to quickly set up voice memories for a new contest
 that sounded exactly like your normal mic voice without any additional
 editing.

 Im trying to understand the need to even *consider* a KDVR
 module.

 I use N1MMLogger, and have for over 4 years now.  I can
 record, not only messages, but numbers and letters and
 phrases into the computer (pre-air processor, using my air
 mic) and off air audio, up to the limiting amount of storage
 that my computer's hard drive has (zillions and zillions of
 messages, hours and hours of QSO's!).

 The Logger software can parse the letters and numbers.  It
 sends, not only pre-canned signal reports, but dynamic
 callsigns and serial numbers live.  If I choose to, I dont
 even have to talk at all in a SSB contest (ever work Jamie,
 NS3T?  You worked a DVK!).

 Not only this, but with the Enter Sends Message feature of
 Logger, I input the callsign and hit the enter key, and the
 software sequences the correct function key for the QSO step
 automatically.  It even logs the Q when done and sends QRZ
 for the next one.

 In multioperator situations, I can have all the operators
 using the station record the messages and when they take
 their shift, they press CTRL-O, put in their callsigns, and
 the software will load the Logger's DVK with their own
 personal voice message files automatically.

 Although I use a MicroKeyer 2, K3 makes interfacing to the
 computer as simple as plugging in the soundcard line out
 into line in on the back of the radio and plugging the
 soundcard in (not really needed, but useful if I set Logger
 to record each QSO) into the line out of the K3.  So, worst
 case, you need a USB to serial adaptor for CAT and two 1/8
 inch stereo cables for audio I/O.

 If I ever want to go portable or operate at another station
 with my K3, I take my MicorKeyer 2 and the K3 interface
 cable with me.  Then, one single USB cable is all that is
 needed to interface the computer to the MicroKeyer 2 for
 full DVK, CAT and all other feature functionality in SSB,
 CW, RTTY and PSK, along with any other soundcard based mode
 I desire to use (The MicroKeyer 2 has its own built in sound
 card).

 By the way, N1MM Logger is Freeware.

 I own lots of options for my K3, but KDVR is not one of
 them.  Is there any compelling reason to even *own* this
 accessory, other than having a computer-less environment
 which, in today's contesting environment, is not going to be
 very competitive (unless your QTH is P5, Mt. Athos or
 something exotic)?

 Hi Barry,

 Yes, I was using the KDVR3 for voice keying - really I only used it
 for my CQ(s). N1MM doesn't explicitly support use of the KDVR3, but it
 does allow you to send arbitrary commands to the K3, so I use the
 commands that emulate pressing the M1-M4 buttons. I was pleasantly
 surprised yesterday when I instinctively hit the Escape key to
 interrupt my CQ when I thought I heard someone calling, and it
 actually worked! I'm really not sure why it works - there may be some
 hidden magic that sends a stop command to the K3 on hitting Escape. I
 have yet to inquire about that.

 Anyway, here are the messages I use for this... theoretically this
 should work for SO2R, but I haven't really tested that thoroughly (I
 only have one K3 at home)...

 F1 CQ,{CATA1ASC K31;SWT21;}{CATA2ASC K31;SWT21;}
 F2 Exch,{CATA1ASC K31;SWT31;}{CATA2ASC K31;SWT31;}
 F3 Thanks!,{CATA1ASC K31;SWT35;}{CATA2ASC K31;SWT35;}
 F4 {MYCALL},{CATA1ASC K31;SWT39;}{CATA2ASC K31;SWT39;}


 The main benefit of this is that it avoids all of the hassles of
 getting the audio routed through the computer working right and
 sounding decent - instead you just plug your headset (or fav mic)
 straight into the radio and go. Message recording is done with the
 buttons on the radio. Listeners should be unable to distinguish
 recorded vs live audio, other than by the repetition.

 A possible down-side is that N1MM doesn't know when the playback of a
 message ends - in fact it doesn't even know that a message is being
 played. Things like repeating (or, worse, dueling) CQs could be a bit
 tricky.

 For something quick and easy, it works quite well...

Re: [Elecraft] IF Output Buffer Gain Mod

[Andrew Faber]

Don,
By the way, this is an odd and awkward way to add a sub receiver to the 
K3.
  If you use an Icom 756 Pro to do the listening, it's also an odd and 
awkward way to add a bandscope to a K3.  I did this in CQP and it works 
fine (thanks to W0YK for the tip a few years ago).

 (mine) and it looks like about 2.5 mV (P-P).

 Does that look about the right order of magnitude???

 Ken,

 I have already made this modification to my K3. But I have not tested
 it. So your email triggered a curiosity to check it. Since the test gear
 is in the basement and the K3 is here in the shack, I thought of
 connecting my FT817 and listening to the IF output. The IF center
 frequency is 8.215 MHz more or less and so you can listen above the IF
 and below the IF to what stations are transmitting. The FT817 was chosen
 because it is highly portable and tunes to 8.215 MHz easily. You could
 do an A/B test on signal level. There were a lot of signals on 20m and
 so I had a lot to hear. If you put the K3 on say 14.350 MHz, for
 example, then a signal at 14.325 MHz is going to be 25 KHz above the
 8.215 MHz IF or 8.240 MHz out of the IF output. This is because the IF
 signal is inverted and goes up in frequency as you go down, in this case
 down from14.350 MHz. The signals are going to be LSB for the same
 reason. You could tune for WWV at 10 MHz to have a stable signal for the
 before/after test.

 By the way, this is an odd and awkward way to add a sub receiver to the 
 K3.

 As usual it seems the thread has mutated into different conceptions of

 freq moves
 faster,
 I had a FT-847 and the tuning on it was jog shuttle an extra ring
 around the
 tuning knob that would move freq very fast depending on how far the ring
 was moved.  Was a bear to get used to.   The ballistic is much
 different, there
 is no learning curve and works well,  you dont even know its there
 unless you
 spin the dial fast.
 It would be like a no hands rate button.   I for one vote for it.

 That would also drive me wild, but then I would not have to use it
 unless I selected it explicitly, so it is quite palatable to me.

Re: [Elecraft] K3 add on kit idea

[Andrew Faber]

Bill,
  We have one of these at P40L-P49Y in Aruba.  It works great for switching 
beverage receive antennas between two radios.  But it's not intended for 
transmitting, so it may not fill the bill.  For transmitting, we use band 
decoders feeding a SixPak (and, as noted, the Yaesu decoder works fine with

  What's great about this vocabulary (and Ed, W0YK, who is a master vintner

According to the list, I would suggest that those who have a problem with 
the K3 audio look up these terms:

 'bright', 'edgy', 'grainy', 'grungy', 'hard', 'harsh', 'muddy', 'piercing', 
'thin'

 to find what best describes what they hear. That may give a common ground 
for describing the effects.

Re: [Elecraft] K3 and N1MM Logger Configuration Rosetta Stone

[Andrew Faber]

Greg,
  I noticed the same problem sending CW to the K3 using my own software, 
CQPWIN, and a Winkeyer when using the Winkeyer to assert PTT.  The cure was 
adding even a small amount of Winkey keying delay (as little as 10 msec did 
the trick).  So if N1MM allows you to do that, you might investigate it. 
Also, using the Winkeyer does allow one to avoid having another line for 
PTT.  And with modern laptops there is an advantage that you can use it 
directly attached to a USB port without any serial port converters needed 
(the Winkey software generates a virtual serial port that the computer 
uses).

 Thanks, Greg. Good information. The sub-programs within N1MM and
 other logging software that sends CW is one of the weakest parts
 of those programs, and it doesn't take much to degrade the CW. In
 general, the faster the machine and the more memory it has
 available, the better the CW works. The computer in my shack is a
 five year old, 1.1 GHz Thinkpad (T22) with 512MB, and it has never
 had a problem with CW, even with a lot of other stuff running at
 the same time.

 Another point. As code for the K3 evolves, the guys who write the
 radio control elements of logging software are pedaling as fast as
 they can to keep up. There are also some differences in the way
 the K3 does things as compared to other radios, and the guys who
 are writing the code for the loggers aren't always aware of them.
 As a result, there ARE some flakinesses in that part of the
 software. All of this is gradually being worked out, as Wayne and
 Lyle implement more features that we ask for and tweak the way
 things operate.

 One example. One thing I LOVE about the K3 is that normal puts
 CW on the same sideband on all bands, whereas most radios use LSB
 on 40M and below, USB above 40M.

 Jim K9YC

Re: [Elecraft] [K3] Programmers reference for KDVR3?

Lee,
  Those commands are in the programmer's reference (i.e., you simulate 
button pushes or button holds).  You should  send a K31 command first, to 
allow the button commands to work.
  I'm planning to do this in ARRL Phone this weekend from P49Y using my 
software, CQPWIN.  I ended up having to devise a process to test the 
messages to see how long they were (to allow times repeating from software), 
and also to allow a deduction in the timing for the normal reaction time in 
pressing the buttons, since the messages stop and start with button presses, 
not with voice actuation.  But it seems to work pretty well.  Email me off

Julius,
  Though we're now drifting off topic from Elecraft, WinKey USB works fine 
on my Vista laptop keying my K3. It also has the advantage of not tying up 
any serial ports, since it runs off the USB port (the driver creates a 
virtual serial port).  You can also use it for PTT, thus avoiding using 
another serial port for that function.

Re: [Elecraft] K3: Qick Split

[Andrew Faber]

I can't recall which one, but I had a radio that worked exactly this way. 
My suggestion would be not to change existing button usage at all, but do as 
Vic suggests, and allow a programmable button to be set to a quick split, 
that would equalize frequency (or maybe put in a variable offset), turn on 
SUB and go into SPLIT mode.  Then it could be used or ignored at will.

 The most important part of quick split is not the offset. I would be happy 
 with an offset
 of zero, or an offset of don't change VFO B.

 What I want is one button that will (at least) activate SPLIT and SUB. 
 This will prevent
 me from carefully finding the station the DX is working with the 
 subreceiver and then
 calling him -- without activating SPLIT.

 Believe me, this is easy to do and very embarrassing.

 If I could have everything I want, it would do three things:

 A-B
 SUB
 SPLIT

 I would want this to be implemented as a programmable function key rather 
 than an optional
 behavior for SPLIT, because there are times when I want SPLIT to be just 
 SPLIT. One way to
 do it would be a menu entry that would let you choose an offset which 
 could be zero or 'no

Re: [Elecraft] Firmware request

[Andrew Faber]

I like this idea also.  But then we also would need some way of knowing when 
a message finishes.  For example, under computer control, if I send a TX 
command to go into TX mode, then a command to start playing a message, the 
radio has to let me know somehow when the message is finished, so that I can 
send an RX command.  This would allow some more flexibility than presently 
exists (for example I could have a repeat interval of 1.5 seconds instead of 
being restricted to whole seconds per the menu).

 I've noticed one possible issue using the KDVR3, wich I've installed 
 today.
 The PTT is controlled directly by the radio, so basically when you go
 for playback the radio goes on TX automatically.
 This is a problem for us, cause on our VHF station we deal with an
 external sequencer who manage to do the timings for relays, PA and the
 mast mounted LNA.
 We use a foot switch to drive the sequencer and the radio PTT is
 controlled via the external PTT socket.
 At the moment the radio doesn't even allow you to go playback if it is
 already on TX.  In any case, even if this was possible it would have
 been a source for possible troubles, cause you have to rely on the
 smartness of the operator who must remember to start the PTT sequence
 well before pressing the playback button.
 It would be better, in a case like this, to inibhit the playback button
 to control the PTT. This should be an option in the config menu, as if
 you are not using any external device, having the K3 going TX with a
 single pressing of a button is quite cool.
 These were my 2 Cents on the topic.

Re: [Elecraft] Beware! (Learn by doing?) :-)))

[Andrew Faber]

What's really fun is that you can adjust the AGC slope on the K3 in the 
config menu.  In fact, if you do this while listening to a very strong 
signal, you can hear exactly what the AGC does to reduce the gain while you 
are making the adjustment.For this contest, I put in the maximum degree 
of attenuation, which helped control the strong signals.

 Call me dense, but I'm not understanding why one would expect that
 turning AGC off would NOT result in a huge jump in AF output.

 AGC turns down RX gain - a lot.  The only time there should be no change
 in AF output is when the RF input is so low that it hasn't reached the
 AGC threshold.

 Maybe other manufactures have coupled AGC on/off with AF attenuation, so
 if the AGC is off, AF output is automatically reduced by 20 dB or
 something.

 For this very reason, I always run with AGC on.  Even when I want the
 rig to act like it's off, I leave it on, set to Fast and then just turn
 the RF gain down to put my signal of interest down near the point where
 AGC is doing very little.  AGC is still on to protect me in case some
 big signal QRM or QRN shows up.

 One idea from the early days of AI is the so-called blackboard model.
 Imagine a garbled sentence on a blackboard, with various experts
 offering their opinions about what each letter and word is based on
 their specialized knowledge of word morphology, letter frequency,
 syntax, semantics, etc. You weigh these opinions based on degree of
 confidence, and once there's enough evidence for a letter or word, you
 fill it in, which in turn offers additional information to the
 highest-level expert, who might be considering the actual meaning of a
 phrase. His predictions can then strengthen the evidence for lower
 level symbols, and so on. Such methods are very algorithm-intensive,
 but might be useful for some aspects of CW stream parsing.

 A neural network could handle this, too, and has the advantage of
 self-organization. This is how I'd approach it (assuming unlimited free
 time--not!). You could use any of several different types of networks
 that have been proven successful at NLP (natural language processing).

 For example, you might take the incoming CW, break it into samples (say
 a few samples per bit at the highest code speed to be processed), shift
 the serial data representing 5 to 20 letters into a serial-to-parallel
 shift register, then feed the parallel data to the network's inputs. Or
 you could use a network with internal feedback (memory), with just one
 input, which itself could be fuzzy (the analog voltage from an
 envelope detector) or digital (0 or 1 depending on the output of a
 comparator, looking at the CW stream). The output might be a parallel
 binary word, perhaps ASCII, or a single output with multiple levels,
 where the voltage itself represents a symbol.

 To make this work, you need at least three things: an input
 representation that provides adequate context (e.g., if you want to
 decode a letter, the input should contain at least a few letters on
 either side of the target); a sufficiently complex network; and a large
 corpus of clean text with which to train the network (probably
 thousands of words, drawn from actual on-air content).

 One classic method of training the network involves placing known-good
 signals at the input, then comparing the desired outputs to the actual
 outputs, and back-propagating the resulting error through the
 network--from outputs to hidden layers to inputs--so that the network's
 nodes gradually acquire the proper weights. Once the network has been
 trained to the point that it perfectly copies clean CW, you can then
 present it with a noisy signal stream. A well-designed network would be
 able to correct dropped CW elements or even letters if its internal
 representation is highly evolved. The network will have learned
 language-specific rules, and you don't have to know how it works,
 anymore than you know how your own brain does it.

 The actual implementation is left as an exercise for the reader. If you
 come up with an algorithm written in 'C', let me know and I'll try to
 port it to the K3's PIC.

Re: [Elecraft] K3 in Carry-on Luggage

[Andrew Faber]

David,
 I've taken my K3 to Aruba several times. I put it in my backpack cushioned 
with bubble wrap and maybe a towel or some clothing.  I just put the 
backpack on the conveyor belt to start with.  I sometimes have to remove it 
for separate handling (only at SFO) and sometimes not.  But no one has ever 
asked any questions about it or thought it to be suspicious.

Re: [Elecraft] Roofing Filter question

[Andrew Faber]

Joe,
 I agree with Jim's advice here.  I have used my K3 several times in CW 
contests from Aruba as P49Y, most recently on a 40m single band operation in 
CQWW, on  a very crowded band.  For that kind of usage, I think the narrow 
CW filter is advisable.  With it, I was never bothered by signals even a few 
hundred Hertz away (unless they had clicks extending into my passband, of 
course), and I think the DSP along with the 2.7 kHz filter wouldn't have 
stopped the loudest signals.
 BTW, one think that makes the K3 such a great run radio is that in those 
circumstances you also have a very clean passband, devoid of the kind of 
digital artifacts that I hear, for example, on my 756 Pro2 on a crowded 
band.

Yes. Remember that the IF in the K3 has EXTENSIVE IF filtering that
perform the function of crystal filters in older radios. Those filters
can be adjusted (front panel knob) to virtually any bandwidth between 50
Hz and 6 kHz, and are the equivalent of a selectable filter bank of 20
or more expensive filters!  The roofing filter simply sits IN FRONT OF
these IF filters. It protects them from overload, AND provides
additional skirt selectivity.

The radio works fine for routine use with nothing more than the stock
2.7 kHz roofing filter. The roofing filters simply improve performance
under difficult conditions. I own two K3s, one with 400 Hz and 1.8 kHz
filters, the other with only a 400 Hz filter. I operated from two QTHs
during the SSB weekend of Sweepstakes. At one QTH I had the 1.8 kHz
filter, at the other I did not. The 1.8 kHz filter helped, but I was
still quite happy with the radio that didn't have the 1.8 kHz filter.

[Elecraft] N6BV report on K3 in SS

[Andrew Faber]

With Dean's permission, I am posting to the Elecraft reflector the report by 
Dean Straw, N6BV, regarding his use of the K3 at K6TA in SS CW.  As you can 
see, he is a convert!

 73, andy, ae6y




[Report by N6BV]:
My primary motivation for operating SS CW for the last 10 years has been to
contribute to the NCCC effort to get/retain the gavel for the Unlimited Club
competition.

This year I also wanted to give K6TA's new Elecraft K3 a real run for its
money on CW, comparing it directly with a Yaesu FT1000MP. I had used a pair
of FT1000MPs in SO2R for seven years operating at the K6TA station.

RECEIVER SETUP

I had used a K3 at the semi-serious CQWW Phone competition at N6RO's place
at the end of October and I was very impressed with it (especially with the
1.8 kHz roofing filter -- SSB sounded very good even with this narrow
bandwidth). But I consider the CW SS as a much higher stress test for any
receiver, because of all the super-strong domestic signals crowding each and
every kHz of any band that happens to be open.

The K3 at K6TA had two roofing filters installed: a 2.8 kHz 8-pole filter
and a 400 Hz 8-pole filter. The venerable FT1000MP had 500 and 250 Hz
filters in both the 8 MHz and 455 kHz IFs.

For both radios I set the AGC decay time constant to fast. The AGC
constants available in the setup configuration menu were left at factory
defaults in the K3.

I operated the K3 with the preamp on, but on the FT1000MP I was forced to
set the IPO to off (the equivalent of preamp off) to hold down overload.

RECEIVER OVERLOAD

During the CW SS, even on a clear frequency, the FT1000MP has always showed
annoying low levels of what I call diddley boops -- more commonly referred
to as IMD products -- created somewhere in the receiver chain. (I've been
told that the IMD is better in FT1000MPs that have had the Inrad roofing
filter modification installed, but this had not been done for the FT1000MP
at K6TA.) In SSB operation and in casual CW operation, I've never been
bothered by FT1000MP IMD. But the CW SS is a different sort of animal, as I
said.

By contrast, the K3 exhibited no IMD, even when I opened up the receive
bandwidth to 2.8 kHz and discovered that I was surrounded by S9+30 dB
signals. No diddley boops at all. Furthermore, the number of signals with
objectionable key clicks was far less than I heard using the FT1000MP,
especially when the rain static on Saturday night rose to S9+20 dB and I was
forced to use the Noise Blanker on each radio to try to knock down the
noise. The K3's Noise Blanker, used with non-aggressive settings for both
hardware and DSP noise blanking, did help knock down rain static (to only S8
or so) while creating far less overload problems than did the 'MP's Noise
Blanker.

Interestingly, the K3's 400 Hz filter sounded somehow narrower than the 500
Hz filters in the 'MP, more than the nominal difference between the rated
filter bandwidths. I used the 250-Hz filters in the 'MP when I used it for
SP in SO2R on the second band, while I kept the K3 bandwidth (both roofing
and DSP) set to 400 Hz 95% of the time I used it as the CQ radio. And I didn
't find that I had to use the RIT very often with the 400 Hz filter, while I
did have to use the RIT often when I had to narrow the DSP filtering down to
250 Hz while CQing.

COPYING THE FULL EXCHANGE

The quality of the K3's audio, the lack of overload and the action of the
AGC seemed to make copying a full exchange much easier for me. I feel like I
required less fills on the K3 than on the FT1000MP. (We'll see after log
checking whether my UBN report is actually better.) Even when a QRP station
faded considerably, the K3 had enough gain reserve and sensitivity so that
the station didn't disappear altogether.

In fact, the presence of signals on the K3 reminds me of the way my old
Collins 75S3B used to work, with strong signals sounding stronger (without
blasting your ears), while weak signals sounded weaker, but still copiable.
I think Elecraft has gotten the AGC slope characteristics right in the K3.
(That refers to the curve of output audio level versus input RF signal to
the receiver.)

I also like the way the K3's RF Gain control works like a conventional AGC
system (the FT1000MP does also), with the S meter rising as the RF Gain
control is backed off, in effect setting the AGC threshold level. (I dislike
the way the RF Gain control works in my Orion I, but that's another story.)

K3 TRANSMITTER

K6TA is located relatively close to N6RO, and he was using two K3s in SO2R
this SS CW. I tuned across Ken's S9+30 dB signal numerous times and marveled
at his complete lack of key clicks. Elecraft got this right on the K3, for
sure. I still heard far too many weaker signals (only S9) with really
objectionable key clicks.

Before the contest, K6TA marveled at how the Alpha 87 enjoyed the RF
coming from the K3 -- with no leading-edge spikes in power that would
occasionally shut off the amplifier while using the FT1000MP.

Oh yes, this is the 

Re: [Elecraft] K3 SSB is it really better

[Andrew Faber]

Rich,
 I've used the K3 in both SSB and CW contests from P49Y.  SSB works great, 
in part because it retains very good intelligibility when cranked down 
pretty narrow (i.e., below 2.0 kHz).  It seems to work better to use the Hi 
and Lo mode instead of Shift and Width.
 OTOH, for CW, the rx is really great because of the ability to disregard 
strong adjacent signals.  While that performance capability exists in SSB 
also, in a contest it isn't as dramatic an improvement over other receivers 
for the simple reason that in SSB, much of the interference you are trying 
to eliminate is really in the passband.  It's splatter and distortion 
products from adjacent signals, many of which may have their processors 
turned way up.  The K3 doesn't generate the digital byproducts as my Pro2 
does, and that is helpful, but there remains the real interference caused 
by the other signals.  So the net improvement from the great rx qualities 
doesn't turn out to be as useful in SSB as in CW.  In other words, the bands 
are still a mess in a major SSB contest, and the best rx in the world can't 
eliminate all the mess.

I'm curious what others are finding with the K3 on SSB in contest 
conditions.  I've had mine for a few months and the difference between my 
mkv and the K3 is like night and day on cw.


I havn't had a chance to really test it out on SSB.  I'm getting ready to 
travel to K5NA's for CQWW and I wonder if its worth taking to replace a 
ProIII or MKV on 20 meters which will be the money band (unless 15m opens

20m will be a mess and I'd like to think the K3 will help with crowded

Re: [Elecraft] K3 - first impressions

[Andrew Faber]

Joe,
 I find the spectrum scope to be very useful in the an SO2R situation. For 
example, at home I use a K3 as my normal run radio and a 756 Pro2 as a 
second radio.  The K3 is a much better run radio mostly because of its much 
superior receiver performance.  OTOH, the spectrum scope on the Pro2 is very 
helpful in trying to find band openings, locating activity on a quiet band, 
looking for bare spots on a crowded band, etc.  The visual display is a more 
efficient way to get this information than by turning the knob and relying 
on your ears.  I'm looking forward to trying LP-Pan in the future to add 
that facility to the K3.

Re: [Elecraft] K3 SO2R in IARU

[Andrew Faber]

A quick note.  I operated casually with my K3 barefoot, CW only, for about 
two hours.  I was using full break-in.  One feature that I noticed was the 
ability to tune the subreceiver while CQing and actually find other stations 
while transmitting.  Of course, I couldn't make out fully what was being 
said, but could find a station and get little snippets of their 
transmission, then listen to them fully after my CQ stopped.  Never tried 
this with other rigs, but it was fun with the K3 and full break-in.

Those dashes sound a little long.  The formula normally used to calculate

dot length (msec) equals 1200 divided by wpm.
 Thus, at 22 wpm, the dot length should be 54.5 msec.  Dashes are normally 
three times as long, i.e., 163.5 msec.

Re: [Elecraft] K3 CW speed request

[Andrew Faber]

Drew,
 I don't think that is correct.  Normal CW has a dash that is three times 
as long as a dot. If you have dashes as short as twice as long as dots, the 
code sounds very strange.  The ratio, i.e., three to one, is purely of the 
length of the character.  Normal spacing between dots and dashes is one dot 
length, independent of the dot to dash ratio.  If the transmitted code 
sounds OK, and the dashes are truly as long as you say, then the speed 
control is mis-calibrated.
 I note that the K3 has a menu entry for what they call CW Weight, defined 
as the dot to space ratio (although often CW weight is used to mean the dot 
to dash ratio). Not sure if there is a way on the internal keyer to vary the 
dot to dash ratio. Most outboard keyers allow you to play with the dot to 
dash ratio, and some people like to vary it a bit from three to one.

Dahs are actually twice the length of dits, I think. Or technically,
the dah period is twice the dit period (i.e., a dah sound plus its
space is equal to two dit sounds and their spaces).

I measured the dahs instead of dits because I don't have a keyer; just
pluged my mono straight key plug into the paddle jack and it gives
dahs.

I measured the period by averaging over five dah periods with the K3
readout set at 22 wpm and 21 wpm, giving periods of  0.207s and
0.219s, as mentioned. I measured the sidetone at the headphone jack
using audio waveform software.

 OK, now I understand: your times are for a dash plus one space.  So, in 
effect a dot would be one quarter of that length at normal weighting. 
Sounds like the calibration may be within the error of measurement.

Ok, using your formula, and allowing for my measurement of dah periods
(not just dah sound portion of cycle), substituting equivalent dit
sound time (at assumed 3:1 ratio), I get the following conversions:

22 wpm K3 readout
measured 0.207 dah period
51.8 msec dit sound equivalent at 3:1 ratio
23.2 wpm calculated by the 1200 formula

21 wpm K3 readout

Re: [Elecraft] K3 Key-down on power-up

[Andrew Faber]

I would vote not to make Test mode persistent.  While I find it very useful, 
it can be a trap for an inexperienced K3 user, to whom it might look like 
the radio simply isn't working.  There is no indication that the radio is in 
Test mode, other than the failure to transmit.

Once it happens to you, you get gunshy about turning the rig on with

Re: [Elecraft] Measuring power output of an SSB transmitter

[Andrew Faber]

Al,
I'm  confused.  I always thought (at least before I became a lawyer and 
stopped thinking about such things) that to reconstruct a waveform you 
needed to sample at twice the highest frequency of the Fourier components 
contained in the signal waveform.  For a sine wave, that would be twice the 
frequency.  For a square wave, that would be virtually impossible to do 
accurately, since it is composed of an infinite series of sine wave 
harmonics, though you could approximate an accurate waveform to any degree 
desired by sampling ever higher in frequency.  Are you saying something 
different, or do you mean that for a narrow-band signal, you have a 
practical high-frequency cut-off, and thus a practical limit on how fast you 
need to sample?

Actually, for a narrow-band signal, you only have to sample at twice the
BANDWIDTH, not twice the frequency.  So long as there are no interfering
signals around (reasonably accurate when measuring a transmitter),
so-called undersampling works fine so long as:

1.  The sample rate is more than twice the bandwidth.
2.  None of the harmonics (sample_rate/2) fall close to the signal.

Sampling at twice the bandwidth will allow you to accurately extract
frequency information about a signal, or if all you were viewing were
sine waves. To view the actual waveform, however, you really want to
sample at at least 4x or 5x the bandwidth, or, even better, 10x the
bandwidth.

Re: [Elecraft] K3, 15 Pin Acc Cables - Commercially Made

[Andrew Faber]

Don,
 For the benefit of Bay Area locals, I also found such a cable at my local 
Fry's Computer Store.  It was necessary, because one of the band output 
signals is on pin 9, which is normally not present on the VGA cables.  I cut 
the other connector off the cable and wired up a special one to fit my 
TopTen Yaesu band decoder (which works fine, BTW, with the K3).

I've found two (2) ready made cables that may be of interest to K3 
owners

when using the ACC Socket.  The ACC socket is referred to on page 18 of my
manual as AUX I/O with the caution that this is NOT a VGA video 
connector!
Well, it sure looks like a VGA connector but alas, no video output from 
the

K3 - shucks!

For those who just don't want to fabricate a cable, most commercially
available VGA cables do not include the #9 pin and for some that do, the 
pin

is not connected to anything. Poo!

Fully connected commercial cables found!

The first is a VGA Splitter Cable (Y cable) with one male and 2 female
ends.  It is offered by Cables Unlimited (www.cablesunlimited.com) and is
their part number PCM-2250.  Search this part number on their site.  It is
listed on their site for $14.99.  All 15 pins are present and connected.

This Y cable is carried by my local Microcenter (www.microcenter.com) 
and

is their part number 028126.  I bought it for $9.95.  You can see it at:

http://www.microcenter.com/search/search_results.phtml?keyword=028126submit
.x=17submit.y=12

The second cable is a Fully-Wired  Straight Thru, HD15MM cable with all
15 pins present and connected.  The one I bought is a 3 foot Male to Male
(although it is also available in other configurations) - no snickering!

It is made by QVS (www.qvs.com) and is their part number CC388B-03.  You 
can

search this part number on their site.  I don't believe that QVS sells
directly to consumers but you can probably find their products at most
computer stores.

Again, I found it at my local Microcenter.  It is their part number 
810150.

I bought it for $14.99.  You can see it at:

http://www.microcenter.com/search/search_results.phtml?keyword=810150submit
.x=15submit.y=9

I've checked each of these cables and they do indeed have all 15 pins
connected - at least the one's I bought do (caveat filed just in case they
change their manufacturing process)!

I don't have any financial interest in any of the above and, as usual, 
YMMV.

I read Lyle's postings faithfully.  I have checked them again

certain radios that do not reach PEP even when showing normal
ALC.


You can expect the firmware release to fix it in about a week

In this case there should be no DC shift (microKEYER II is AC

This does work.  I just made 4 qsos in the contest with Field Tester Ed 
Muns, P49X, using my K3 without any special software.  What works for me is 
to record messages in memories in CW mode, then send them in Data mode (FSK 
D).  At the end of each message add the character Greg describes, all sent 
as one character.  Make sure the text decoder seems to be reading the 
message correctly, as sometimes either less or more spacing than sounds 
right on CW seems to be necessary to get the message just right.  The TX 
TEST mode is very helpful for this.

about it or not, but would be interested in solving this problem, as it
impacted my ability to use our beverages on RX.


At the Bavarian Contest Club's contest QTH we use a simple relay to 
disconnect the rigs reception antennas whenever the rig goes to a TX 
state. A simple relay, a few simple parts and the PTT/KEY signal do  the 
trick.


Many rigs do not switch the RX antenna input when transmitting, so  this 
always requires a bit of care - especially at high power levels.

Re: [Elecraft] K3/100 RF Feedback/Spurious oscillations ?

[Andrew Faber]

Stewart,
 I reported something similar after CQWW CW, and there was some discussion 
about isolation between the RX antenna input and the TX stages of the radio. 
I'm not sure if there is a plan to do anything about it or not, but would be 
interested in solving this problem, as it impacted my ability to use our 
beverages on RX.

Very strange effect noticed today when tuning up on 20m.

At power levels above 20 w on 14.175 my external Palstar SWR meter
would suddenly leap from 1:1 to above 5:1. Also the K3 SWR display
showed similar. High current was also reported. No problems with
either a TS850S or K2, both OK up to 100W.

Switching the RX Ant switch to the main antenna or removing the RX
Antenna  BNC lead cured the problem.

I use the RX antenna input for 2 x Pennant loops for the LF bands,
but find that they sometimes give a better SNR than the main
antenna on higher bands. The main antenna system is a doublet fed
with open wire feeders into a fully balanced (no toroid on output)
ATU.

My initial thoughts is that there might be some spurious output
generated by an obscure feedback path from the RX antenna input.
If this output were on a frequency well separated from the desired
then it could show up as as high SWR.

What think Ye ?

Re: [Elecraft] Band decoder and Tx Inhibit

Re: [Elecraft] Band decoder and Tx Inhibit

[Andrew Faber]

Chris,
Good luck with it.  I have the TT Decoder powered by an independent 12 volt 
source.  It has internal pull-up resistors, so there appears to be no 
connection needed other than the ones I mentioned.  It took me a bunch of 
trial and error time to figure this out.  Let us know how it works.
 I emailed N3RD a while ago to let them know.  Dave said he had a K3 on 
order, and that they did intend to offer K3 cables.  I made up a generic 
cable from my TT DX Doubler to the K3, and that seems to work well also. 
It's nice to use inputs all on the back of the K3, so there are no cables to 
the front panel.  Only issue is that the Mic and Headphone jacks on the back 
are pretty frail and don't make very positive contact sometimes.

Re: [Elecraft] Transverting - DB15 UK supplier?

[Andrew Faber]

Bob,
Also, bear in mind that some cables that are billed as VGA monitor cables 
actually only use 13 pins, not all 15.  In fact, they have Pin 9 missing, 
which is one of the pins used for the Band Data Output signals.  One of the 
pins in the third row (i.e., 11 to 15) is also missing.  So be sure that you 
get a cable that actually has all 15 pins in the jack.
 I was quite surprised to note this when I was in a computer store looking 
for cables to cut up to use to connect my K3 to a Top-Ten Yaesu band 
decoder.

You need to look for DE15, not DB15.  The letter after D designates
the shell size, so DB would be the wider type (25-pin type normally
used for parallel ports on PCs).   The type used for VGA is DE15 (15
pins in the same shell size as the DE9 used for serial ports).

Re: [Elecraft] K3 as successor

[Andrew Faber]

Dave,
 Yes, I was listening to a very weak J5C last night on 80 next to his 
pileup.  On the K3 I could factor in some noise reduction and pull him out. 
On my 756 PRO2, when I turned on the NR, I got various clicks and pops on 
his frequency due to the pileup and couldn't read him.
 I'm normally skeptical when anyone says they can hear a signal on one 
radio and not on another, but this was a case where it was true.   The K3 
passband is completely free from digital artifacts, even with the NR on.

getting long in the tooth, like me, however, so I've been reading up on 
replacement candidates.


Trying pileups on 80M and other bands with an ICOM candidate was 
disappointing.  The conditions are as follows:


DX at noise (you know, he's there, copiable at least part of the time, but 
any attenuation and he's not there) listening up 1.  Pileup: 
REALLYBIGSIG1 up 1 and REALLYBIGSIG2 up 2.  Result: artifacts all over the

Back to the yy zo to make the Q.

 A Heil Kenwood adaptor works fine.  I've used it.  You can also simply 
plug both the mic and the phones connectors from a Pro-Set into the back of

[Elecraft] K3 displays

[Andrew Faber]

Hi all,
 I'm  new to the reflector, but did use my brand new K3 (ser #76) last 
weekend in CQWW CW from P49Y, as a single band 40M HP entrant.
 I loved the K3, and never felt that I was bothered by adjacent channel 
interference.  Also, the sound was much cleaner than with our PRO2s, without 
any digital clutter or artifacts floating around in the audio field.
 One feature I would like is to be able to display certain parameters 
without having to rotate the knob and thus change them.  These include:
 --RIT.  I've been in email contact with Wayne and understand that he may 
add an option for continuous display.
 --Bandwidth.  I did change the settings frequently, depending on the size 
of the pileup. I have the 400 Hz 8-pole and 200 Hz 5-pole filters.  I 
generally used a wider setting, but did go down to 200 and 150 at times.

 -- Power.
 Not sure how this would be implemented, as the natural approach (tapping 
the control) already has another function.  Maybe two quick taps?
 I'll post more comments later and would be happy to answer any questions. 
Overall, the K3 was a delight to use.  Congratulations to all involved in 
its development.
