[Elecraft] K3 filters

[Benny Aumala]

Nobody seems to talk about Group Delay Time.
The steeper the LC or Xtal filter is, the higher are Group Delay variations.
One filter side up, the other side down.
In narrow filters these are very close.
This is at least one reason for "ringing".
8 Xtal filters are clearly steeper than 5 Xtal types, and have higher
variation of Group Delay.

DSP makes very steep  filters WIHOUT group delays.
K3 concentrates best selectivity here. Correct!

Roofing filters just protect the rest of RX from too big signals.
We tend to think that roofing means final selectivity. Wrong!

It would be interseting to measure Group Delays between different
Xtal roofing filters with and without DSP.

Let us imagine an ideal 9MHz SSB-filter plus/minus 1,5kHz. 10 Xtal 
filter has

shape factor of 1,33. Now  -60dB points are plus/minus 2kHz.
Now, the Group Delay difficulties are on both side from 1,3 to 2,2kHz.
Now the best way of using DSP is to delete these variations by
choosing (IF) DSP bandpass of plus/minus 1,2kHz. Still OK for contest,
but you do not agree. A 3kHz good Xtal filter became only 2,2kHz final 
selectivity.

I would rather use 5 xtal roofing and all bandpass DSP.

Group Delay was importand in analog TV-transmitters (ancient times).
It was found the hard way. Once understood, it was controlled
and measured every time.  Final solution was to use transmitters with
normalized IF signal processing. Centralized block for pass-band filtering
with standard Group Delay was the answer.

Re: [Elecraft] K3 filters

[Simon Brown (HB9DRV)]

It's a 16-bit mono recording taken via the line-out using a high-quality 
soundcard (USInterface.com Navigator). The K3 operator isn't all that 
skilled but he's got half a clue as to what's going on (on a good day at 
least).


The antennas was a sloping 20m dipole, radio tuned to 40m with preamp on.

After tidying up the pigsty I'll see if 20m is alive and make another 
recording before getting on with mode coding.

Re: [Elecraft] K3 ease of use

[Simon Brown (HB9DRV)]

I have a TS-2000 next to the K3, IMO the K3 is easier to use but the TS-2000 
does offer more - 2m/70cms, satellites, memory scanning etc.


Given all that it does it's maybe cruel to berate the TS-2000. I am very 
interested in UI work and find the K3's layout to be very good. The only 
thing I would like is a button I can press in CW mode to toggle between 
current bandwidth and 1kHz, this can probably be done by programming PF1 or 
PF2, a 'tap' button such as M1 would be preferable.


I admit to only having read the manual while assembling the beast, other 
than that I just wind the filter width down, set a pleasant AGC and listen. 
And write code, lots and lots of code!

Ladies & Gentlemen, may I present Dave - someone who reads manuals :-)

When pressing Width I notice that if I accidentally rotate then the width is 
changed - I would prefer it to ignore turning when pressed, but this is 
exactly what I was after.


Must take the manual with me next time I take the spaniels out for an 
Erdinger or three.

this is representative of the K3.  At times it sounds distorted (noise
modulated?, AGC?) and also, the cw tone often doesn't sound great to
my ears.  Additional recordings would be great - from you or any other
K3 owners out there with a soundcard.

I have now tried a Delta-44 soundcard - and have concluded that there's some

find and have got nowhere so will take this up with K3 support.


The speaker audio is great, the audio from lineout is hollow!

[Elecraft] [K3] Dual audio input

[Toby Deinhardt]

Hi,

coming soon is the 10m ARRL "Pray for Sun Spots" Contest, which will be 
my K3's first contest.


Currently, AFAIK, it is not possible to use a microphone input and line 
in at the same time, due to firmware restrictions. I would like to be 
able to use my laptop as a DVK but because the laptop does not offer a 
bias voltage, I need to connect the microphone directly to the K3.


Is there any chance that the next firmware update will address this?

By next friday??


I'm only asking so that I can plan on what I need to take with me, when 
I go to our club's contest QTH, about 120kM from home. If dual audio 
input does not work by then, my BVK (biological voice keyer) will do 
just fine.

[Elecraft] K3 display for contesters

[DOUGLAS ZWIEBEL]

Hi Dick and other contesters who might be potential buyers but who are
now concerned by Dick's post:

You said, "but there are many parameters that need to be available
at-a-glance: both VFO frequencies, bandwidth, shift/PBT, RIT/XIT
power, vox, AGC, RF Gain, preamp, notch, NB, receive antenna status,
power, etc. "

Well, I think that I'm a pretty serious contester and completely
disagree (except for the QRG of both VFO's).I am able to hear the
different characteristics you mention.  Narrow BW sounds a lot
different than wide.  I'll adjust it (not that I do that much) based
on what sounds right; not by looking at a display or "the numbers."
Who cares what those are...it has to sound right.  Same with
shift/pbt.  As for RIT/XIT, for me, the only thing that matters is if
it is ON or OFF.  If I twiddle either, it will be for a specific QSO.
And as soon as I'm done with that Q, I zero it by tapping the clear
button.  If I feel that I need to twiddle it again for another Q, well
then the offset does automatically show up (as I understand it...I
don't have my K3's yet).  Power?  Why do you want to monitor that.
Isn't it "set it and forget it?"  Vox?  Are you turning vox on and off
during a contest?  Why?  Basically, I just do not see why these are
important to you unless it's just a matter of that is what you are
used to now.

You also said, "I can't afford to spend time twiddling knobs to
determine the current state of the transceiver."  I agree!  In fact, I
would say that during a contest, you can't afford to be twiddling
knobs period.  If you are adjusting AGC, Shift, Bandwidth RF gain,
Preamp, Notch, etc during a contest, sounds like DXing more than
contesting to me.  Time spent twiddling knobs is time not making Q's.

I won't dispute that these may be (seem?) "important" to you now, but
I know tons of contesters who simply "do it by ear" and usually don't
twiddle knobs at all.  Like K3ZO, on cw I like to select one BW
(usually fairly wide) and that's how I operate the entire contest.  If
I have to narrow it for one situation, I immediately "put it back" as
soon as that Q is done.

So that's MY style of contesting.  The purpose of this post is simply
to present another POV (mine).

[Elecraft] roofing filter confusion

[Bill Tippett]

WC1M:

>The Orion has a
famous flaw where it switches in an amplifier to compensate for losses in
the 500 Hz and 250 Hz roofing filters, but the gain is too high and the
dynamic range goes all to heck.

Dick I believe the flaw in Orion was actually routing the
signal first through the 20 kHz roofing filter plus following
12 dB amplifier before the 500/250 Hz filter and the second 12
dB amplifier.  IMD products were generated prior to reaching
the narrow filter stage...similar to the problems up-conversion
rigs have using 15-20 kHz roofing filters.

>Hopefully, variable gain will compensate for losses with no other distorting
effects. But even if it does, what's to be gained by using an 8-pole filter
in the first place? Can it be demonstrated that the 8-pole filters improve
selectivity beyond what the IF DSP does? Have tests been run to determine
specific gain settings for each filter offered by Elecraft so dynamic range
won't be compromised?

As can be seen in the following IMD performance, the 8 and 5-pole
filters have similar performance (at similar bandwidths):

Filter20kHz  10kHz  5kHz  2kHz
200 Hz, 5 pole100+   100+   100+   95
250 Hz, 8 pole100+   100+   100+   95
400 Hz, 8 pole100+   100+   100+   95
500 Hz, 5 pole100+   100+   100+   94
1 kHz, 8 pole 100+   100+   10094
2.7 kHz, 5 pole   100+   98  92n/a
2.8 kHz, 8 pole   100+   100 93n/a

http://www.zerobeat.net/mediawiki/index.php/K3_Roofing_Filters

Gain compensation for the K3's 8-pole filters is set in the DSP stage
according to individual insertion loss measurements supplied with each
filter, per the filter installation procedure.  Orion's gain compensation
for the 250/500 Hz filters was set much earlier in the IF chain which led
to the problems with those filters.  There were no corresponding problems
with the 1.8 kHz 8-pole in Orion because its insertion loss was low enough
not to need additional compensation.

Regarding possible advantages of 8-poles versus 5-poles,
Elecraft claims the 8-pole may have better BDR performance, but I
suspect any such theoretical advantage would be overridden by
transmitted signal issues such as key clicks, phase noise, etc.

73,  Bill  W4ZV

P.S.  Been in 6Y5 this week and *hoping* I have a big box waiting at my

RE: [Elecraft] LOW RESALE VALUE OF LOW SERIAL NUMBERS

[Steve Sacco NN4X]

Let's use a bit of logic here: It's not possible to pass judgement on 
the future resale value of low SN units, except in retrospect.  Who 
knows what the future will bring?  Perhaps, for whatever reason, 
there will be hardware revisions which make the K3 mark II, mark III, 
etcetera more desirable.


Even if that doesn't occur, a lower SN would denote an older unit, 
and would therefore be considered less desirable, except perhaps for 
the very lowest SN's.


Analagous with this, IMO, folks need to recalibrate their thinking 
with respect to radios.  The days of buying a Collins S-Line, and 
having a top-line rig for 30 years, are OVER.


Nowadays, radios are essential computers with enough RF hardware to 
let them RX and TX.  We all know what the PC/computer/semiconductor 
markets looks like: they get better/faster/cheaper every month.  A 
ten year old PC?   No thanks!  It'll be the same with 
radios.  Imagine what'll be possible in DSP technology ten years 
hence!  Same with display technology, and networking interfaces.  Who 
would want a 10 year old K3?  Not me!


Awhile ago, there was an angst-ridden thread here about the 
firmware.  The general concern was: "What if Elecraft went out of 
business in five [or some other number well into the future]?  What 
would happen to the firmware code?"  I nearly fell out of my chair, 
laughing.  Who cares?!  In five years, there will be even 
cooler/higher performing/less expensive radios available.  Folks were 
getting their panties in a knot based on 50 year old assumptions 
(that the radio will be viable for a long, long time), and it was an 
unfortunate waste of perfectly good energy.


I'd also hope that we're able to drag ourselves away from our 1950's, 
analog-based technology, and move to digital modes.  People are 
asking about AM?  Why not spark gap?  Let's move FORWARD.  We're 
supposed to be on the cutting edge of technology, and we're not there 
anymore.  Not even close.


All IMO.

Re: [Elecraft] K3 filters

[Geoffrey Mackenzie-Kennedy]

Benny,

Group Delay is I agree a very important consideration, but I would suggest 
that another very important factor which determines how well a receiver will 
perform when the DSP is used as the main 'selectivity block', is the odd 
order dynamic range of the first IF filter and *everything* else which 
follows it, which includes the DSP. If you widen up the first IF filter or 
its skirts and do NOT have a 'strong' system, in a strong or busy signal 
environment there is a real possibility that some of the IMD products 
generated within the IF filter and / or following stages will appear within 
the DSP's passband. An AGC loop after the filter can help if its component 
parts or action do not worsen IMD, but if activated will cause weak signals 
just above the noise floor to become 'weaker', or even disappear - i.e. the 
DX you are chasing.


These comments are not only about the K3 but receivers in general.

I suppose that another problem is the cost of a 'strong' system, which 
includes that of high performance Crystal filters.

Fw: [Elecraft] K3 display for contesters

along with a totally different display set of functions ?

On the one hand, I've done a lot of contesting with the K3 since July and
have survived without these displays.  Bandwidth is indicated in two ways,
both the crystal filter setting and the filter bandwidth icon giving
relative width.  I quickly adapted to this UI and feel pretty comfortable
with it.  One worry is if I've adjusted the DSP bandwidth to an 
intermediate

value between crystal filters ... what is it?  But in contesting, I mostly
just want to be sure I'm at a known bandwidth and for that I can hit the
XFIL button or use the two PRESETs.

OTOH, I agree that the parameter displays you describe below are very 
useful

in contesting where you don't want to take time to turn controls back and
forth to activate their display momentarily.  This input is already in the
K3 firmware hopper and Wayne will deal with some of them in a future
release.  For example, there might be a configuration parameter to
constantly display RIT offset in the VFO-B display area.  Or, functions 
for
each of the controls you mention, e.g., POWER, that can be assigned to a 
PF

button for instant display in the VFO-B area.

Subject: [Elecraft] K3 display for contesters

N1EU recently posted a query about the lack of a full-time
bandwidth display. Many replied that all you have to do is
turn a knob to see the current bandwidth. Evidently, this
also applies to a number of other operating parameters,
including output power(!)



This is all well-and-good for casual operating and DXing, but
it's a real liability for serious contesters. In a contest,
the last thing I want to do is take my hands off the
keyboard. I need to be able to see certain important
transceiver setting with a quick glance in order to make a
decision whether or not to move my hands. Bandwidth is one of
the settings I need to know, and the roofing filter selection
isn't sufficient -- I need to know the ultimate selectivity
provided by the DSP. I haven't had time to study the K3
manual in depth, but there are many parameters that need to
be available at-a-glance: both VFO frequencies, bandwidth,
shift/PBT, RIT/XIT power, vox, AGC, RF Gain, preamp, notch,
NB, receive antenna status, power, etc.



Basically, you need to be able to see any setting that might
affect transmission or reception. For example, if the
bandwidth is too narrow, and you don't realize it, you may
not hear stations calling slightly off frequency, or they'll
be significantly attenuated. You could have a similar effect
if the notch was inadvertently left on. I can't be required
to remember the last change I made to the settings, which
might have been hours ago. Also, I use two radios and it's
impossible to memorize the settings for both of them. I can't
afford to spend time twiddling knobs to determine the current
state of the transceiver.



Are the LCD display fields fixed, like on older displays, or
are all the pixels under firmware control? If the display is
fixed, the lack of status displays could be a real problem.

Ditto that Doug,

When I'm contesting with my K2 the only knob that gets "twiddled" is the
VFO with an occasional push of XFIL. I can't imagine a big gun station
holding sway on 20 meters moving anything on the rig. They sure don't
have to S+P like we little pistols do.

I've also noticed a disturbing trend on the reflector. That being most
of the negative posts, what few there have been, and none from actual
owners or buyers of the K3, have come from people well known on the
Ten-Tec list and are Orion owners/users.

Kinda makes you go "Hu".
Maybe the boys in Sevierville are getting a little nervous.

RE: [Elecraft] [K3] Which version of K3 Utility ???

[Dick Dievendorff]

1.0.11.21 is the most recent firmware utility that has been published on
Elecraft's web site.

1.0.11.29 is under evaluation by field testers.  One of its new capabilities
to inform you whether or not the version of the K3 Utility you have
installed is the most recent one, or whether it's recent enough to load the
most recent firmware.  

I asked that the version information file be placed onto the Elecraft file
server in order that I and other testers could verify the FTP and
level-check functionality of the new version.

All the K3 versions (and firmware) are tested by a small Field Test team
before being published to the web site.

1.0.11.29 includes changes based on your feedback; it's much less chatty
when there is no K3 connected, and setup allows you to choose a different
installation directory.  

It will be there soon, unless I've made a mistake that requires me to create
another version prior to publishing on the web site.  

After you get to 1.0.11.29 or later, the utility will itself check (with
every "Copy Files from Elecraft") and let you know when it's no longer
current.  This was an idea we got from N6TQS, as I recall.

[Elecraft] K3 display for contesters

[Barry N1EU]

The notion that some/many serious cw contesters don't adjust
selectivity occasionally/often during a contest is absurd.  When
you're keeping a run going in tough crowded conditions, with offending
stations moving in on you from either side, you tighten the receiver
up.  When the offenders move away, you open the receiver back up to
hear off-freq callers.  It's nice to see where it's set.  S&P on
40/20M might require much tighter selectivity than S&P on 80/15/10
etc.  I'm not saying everybody does this, but consider that many do.

There's plenty of room for all kinds of comments, laudatory and
critical.  Everybody's motivation is making the K3 the best radio out
there, and it's off to a great start.

That's true only within the limits of the original hardware. Look at a PC - 
upgradeable in theory, but in practice it's often not long before it's cheaper 
and easier just to buy a new computer.

That said, note that there are plenty of 20+ year old rigs whose performance 
and features are very good and whose price can be very reasonable.

This was a selling point Collins used a half-century ago: their gear was 
expensive to buy, but its resale value was also high.

Here's another way to look at it:

If it costs you $1200 to own your K3 for 5 years, that's 66 cents a day.

[Elecraft] K3 filters

I saved that file (quite a good one and long too),
hastily, being eager to hear it.

Very nice AGC, good hearty audio on the cw note, and
low noise. 

My next reaction was "holy cow, an opening to Europe,
and strong signals too". 

I must have missed that opening on 20m. :-|

Europeans are great DX here in So Cal.

Now I realize his QTH is favorable to EU. ;-)

It's a 16-bit mono recording taken via the line-out
using a high-quality 
soundcard (USInterface.com Navigator). The K3 operator
isn't all that 
skilled but he's got half a clue as to what's going on
(on a good day at 
least).

The antennas was a sloping 20m dipole, radio tuned to
40m with preamp on.

After tidying up the pigsty I'll see if 20m is alive
and make another 
recording before getting on with mode coding.

[Elecraft] K3 filters

[Don Rasmussen]

Barry, I don't know if one can ever be sure if they
are hearing a representative account, the recording
sounded great to me. However, Tree put out a recording
a couple months ago where the signals were just on the
margin and I copied Q5 - every character on my
workstation at work using headphones, while some
others complained they copied "nothing".

I felt pretty special for a while, until I took the
same recording home, played it on my system (through
amplified speakers and copied only noise, maybe 3 or 4
characters. 

So right on the recording being important, but also
the setup on playback.

Simon, I've listened to the clip on a couple of
computers and headphones, and I appreciate your
efforts but I also have to wonder if this is
representative of the K3.

Couldn't the band limits be user programmable, a function of the
firmware utility? Then when you are off to Thailand you can just
program in their limits, and when you come back you can remove them
again.

[Elecraft] Crushproof KX1

[n9jxy]

Since the KX1's controls stick out the top, it's been pretty much imperative 
that it be carried in a hard padded case. It will fit in a smaller, soft 
camera case though, so a couple years ago, I decided to make a protective 
cover using one of those fiberglass repair kits you can buy just about 
anywhere for about $10 and it's worked real well. Although it's fairly cheap 
& easy to do, it's not for the faint of heart or someone who's careless!




First, I made a round sleeve to protect the tuning knob and a U-shaped piece 
for over the other knobs out of thin cardboard, taping them into place with 
that blue tape that painters use. Then I cut holes for the switches in a 
thicker piece and taped it over them. Next, I carefully, but not tightly, 
wrapped two layers of plastic wrap around the rig & taped it together on the 
bottom. I applied a paper towel over that, taping it on the bottom, and 
snuggly wrapped the whole thing in aluminum foil with the seams at the 
bottom.




Next, following the kit's directions, I applied two layers of fiberglass to 
the top & down the sides, holding it tight, especially in the corners, with 
about a dozen rubber bands. I let it hang straight down from the antenna 
connector, though. After it dried, I carefully removed everything, pulling 
excess foil from inside the cover (I actually used etchant to remove all the 
foil, but it's not necessary), and trimmed it so it would extend about ¾ way 
down the sides. I trimmed it up around where the earphone plug would be 
though, so I could leave the phones plugged in, if desired. The trimming 
left some rough edges, so I mixed up another small amount of epoxy and 
sealed everything.




After the cover was completely dry, I cut out & applied pieces of stick-on 
felt to the inside corners & several other spots, which keeps the rig from 
being scratched & creates a snug fit. The end result - I'm able to carry my 
KX1 in about anything it will fit in, and the only abuse the controls get is 
from me using them.

Re: [Elecraft] LOW RESALE VALUE OF LOW SERIAL NUMBERS

I prefer to think that my low serial number K3 will increase in value

Regarding computers obsolence, even hams are adding to the problem.
There's a well-known USB interface for radios that's not supported on

Re: [Elecraft] LOW RESALE VALUE OF LOW SERIAL NUMBERS

[wolfmanjack]

NN4X has some valid points and I like his spirit. However, the funny thing 
about the K3, it was a remark attributed to W0YK that piqued my interest in the 
radio. Basically, I read an article that said Eric and Wayne had captured that 
'Drake/Collins' receiver sound...

That's EXACTLY what's been missing from all the modern radios I've gone 
through! Collins and Drake, state of the art? Nope. But what they have is 
something I've missed for a long time...

[Elecraft] K3 Calibration Problem

[Sanger, Joseph]

Up to the point where I am trying to do the 'TX Gain Calibration'.
(Everything to this point in time has gone exactly as expected; I have
calibrated the Synthesizer successfully, and set up (and rechecked) the
filter settings to match the actual crystal filters instllaed).

 

Here is the problem.

 

When I follow the TX Gain instructions on Page 46 of the owner's manual,
I find a few problems:

 

1)   when I press the ANT button, VFO B says 'NO ATU' .. probably
not an error, since I am in ATU Bypass error.  I guess I was a little
confused by the wording: Switch to ANT1 by tapping ANT.  since I never
see the K3 talking to ANT2 ... 

2)   The real problem is that after setting the power to "exactly
5.0 watts" and holidng TUNE, the power reading on 160 meters only goes
to 1.2 watts; when I tap TUNE to exit, VFO B says: ERR TXG.  Similar
problems on other banads, to wit:  1.8 Watts on 80m, 1.4 Watts on 40m,
1.9 Watts on 20m, etc.

 

I am stuck!  Help!

 

Thanks.

[Elecraft] K3 Calibration Problem

[Dave G4AON]

*Joseph

1. In order to use the ATU and the PA, you need to firstly enable them 
in the menu, then turn the power switch off and on again. The rig reads 
in the accessories and will recognise them (I fell for that one with the 
PA).


2. I also tried too hard to set the power levels... Basically once you 
have calibrated the Wattmeter (and then only if you have an accurate 
external Wattmeter), you then ignore the menu and external power meters. 
Just follow the instructions in the manual, it's easy to fall into the 
trap of trying to set levels manually, this is not how you calibrate the 
power settings the K3 will automatically set the power for you when you 
select 5 Watts (or 50W on high power) and press the "TUNE" button, this 
needs to be done on all bands... If you have really fouled up, reset the 
K3 to the initial start-up conditions by pressing and holding the 
SHIFT/LO knob while powering up. Don't forget to calibrate the VCO 
before going on to the power setting.

[Elecraft] KUSB Universal Serial Bus Adapter?

[Dave G4AON]

You pay your money and you take your chances! I don't need one for my K3 
as I use the shack computer with 8 real serial ports. For portable use 
(with other gear), I have a couple of USB to serial adapters on a 
Toshiba laptop that work well, they were about the equivalent of $30 US. 
I bought two of the same brand as it drives me mad trying to cope with 
Windoze trying to install drivers all the time when you plug an adapter 
into a different USB port to the one it was set-up to use initially.


The "other gear" mentioned above is a Nokia 3210i phone used as a GPRS 
modem and a TS-480, for our UK readers the USB to serial adapters were 
from Maplin.

Make sure you've selected a filter that is at least 1 khz wide for CW
transmit. Otherwise you'll get the ERR TXG message.

Thanks for the tip, Craig.  

But I am using the standard 2.7KHz filter for these calibrations.
(Indeed, the problem seems to be essentially independent of the filter
or mode chosen.)

Re: [Elecraft] KUSB Universal Serial Bus Adapter?

[Don Wilhelm]

Bob,

No you do not have to buy the adapter from Elecraft.

You can buy the one from Elecraft that is known to work, or you can buy 
the $2 one and see if it works - some may, some may not, it is a gamble.


That ine from Ebay likely has some shipping charges with it too, so it 
will cost you perhaps $7 by the time you are done.  One can buy only 6 
of the inexpensive adapters to try before expending more than the cost 
of the Elecraft 'known to work' model.


The choice is entirely yours.

I would suggest a better solution for those who are using a standard PC 
(one that will accept adapter cards), the you purchase an add-on serial 
card.  That is a more reliable (and less hassle) solution than depending 
on USB to serial adapters.  A PCI card with 2 serial ports can be found 
in the $25 price range.

Re: [Elecraft] KUSB Universal Serial Bus Adapter?

[Ed K1EP]

It depends on the adapter and what you want to use it for.  If you 
are just looking for data transfer, I would think just about any 
aftermarket adapter will work.  Some do not implement the full st of 
control lines.  So if you want to use PTT or CW, there *may* be a 
problem.  I am not saying there will be one.  I use a somewhat 
generic adapter when I need the USB port and it works fine for data, 
CW, and PTT.

[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.
73, andy, ae6y, p49y

[Elecraft] DSP NR reduction mode on K3

[Simon Lewis]

Hmm maybe I am not doing something right

When trying to activate NR mode I press NR right ?

And then hold if I want to adjust the level???

Just if I do this as per the manual it says N/A

In tech speak that would say not available to me??

Any ideas.
?

Probably me - it too me long enough to put my glasses on and check that the
PA and PAIO are different entries too!

Re: [Elecraft] K3 Display LCD - Cover?

[Gary Bartlett VE1RGB]

Tnx, Joe.  I seem to remember from my K2s that there was such a film, but
looking under a magnifying glass it the K3 LCD, I see no evidence of any
protective material.  And of course the absence of any instructions to that
effect should be a clue!

   Only problem I have encountered so far was inserting the chassis ground
thumbscrew through the back panel into the mating connector on the RF board.
I had to loosen the rear lower screw on the left -hand side panel
temporarily to get that thumbwheel in without cross-threading, and even at
that it's a very tight fit when you re-do the side panel screw.  The
suggestion to use that technique was removed from the instructions by Errata
B8 of Rev B1 of the Assembly Manual, and I have sent a note to Elecraft
suggesting they put it back in.  Cross-threading of the chassis ground screw
in the RF board would seem to be rather bad news and to be avoided.

   73,
   Gary, VE1RGB

Depends

I put mine in the PC and it worked first time .

These are very difficult beasts sometimes ... It was easier to throw in the
box with the rest of the K3 bits for me!

Less hassle too!

Up to the point where I am trying to do the 'TX Gain Calibration'.
(Everything to this point in time has gone exactly as expected; I have
calibrated the Synthesizer successfully, and set up (and rechecked) the

Here is the problem.

 

When I follow the TX Gain instructions on Page 46 of the owner's manual, I
find a few problems:

 

1)   when I press the ANT button, VFO B says 'NO ATU' .. probably
not an error, since I am in ATU Bypass error.  I guess I was a little
confused by the wording: Switch to ANT1 by tapping ANT.  since I never see
the K3 talking to ANT2 ... 

2)   The real problem is that after setting the power to "exactly
5.0 watts" and holidng TUNE, the power reading on 160 meters only goes to
1.2 watts; when I tap TUNE to exit, VFO B says: ERR TXG.  Similar problems
on other banads, to wit:  1.8 Watts on 80m, 1.4 Watts on 40m, 1.9 Watts on
20m, etc.

 

I am stuck!  Help!

Couldn't the band limits be user programmable, a function of the
firmware utility? Then when you are off to Thailand you can just
program in their limits, and when you come back you can remove them
again.

[Elecraft] 122 arrived and works

[Eric]

Hi all,


My parts K3 arrived in Holland last Friday, spent the afternoon 
building and it works.


Had a problem calibrating TX, one filter position on the main board 
isn't working correctly, so I placed my 2,8 kHz 8 pole in another slot.


Only thing I didn't grasp until now is the fact that I have no idea 
how to put the RX in AM or FM mode?? Just tapping "mode" changes 
between LSB, USB, DATA and CW.



Any help?

[Elecraft] K2 Bargraph

I've reached stage 1 alignment & test on K2 (#6257)and have no 
bargraph display.
Borrowed another K2, put my front panel board in - Perfect. Put my 
control panel in his K2 - no bargraph. Changed MCUs (dangerous 
business)- IC is Fine.
What line on the control panel "enables" the bargraph. What do I check next?
Incidentally Gary AB7MY at elecraft has patience that other 
businesses could use, but even he needs a weekend off.

Re: [Elecraft] K3 display for contesters

[Jon Robert Pellant]

Not in this venue-- maybe on the yahoo group perhaps, we should start a 
discussion of what a K3 HUD (head's up display) might look like. I am sure 
there are a bunch of us that could contribute "gadgets" if we could come up 
with an architecture to support it (e.g., Adobe AIR, Flex, Flash, Java, 
JSR-168, etc. all of which supported on linux, win, and osx).


With a browser-based portal, one could easily design a portal that would 
allow people to do define a 'gadget' layout that would display whatever 
information you wanted from the K3 (via K3's data comm).

Re: [Elecraft] Elecraft K3 Support on the Weekends?

[k4tmc]

Simon, et al,

Thanks for the quick responses.  I thought that with all of us building 
these over the weekend, there would be someone answering support 
questions.  But, I know they have been busy, and maybe need some time 
off to deal with other issues.


I do have the KPA3 100 watt amp to install.

The assembly manual that came with the kit indicates that it is not 
necessary if you are going to install the KPA3.  However, the picture 
in the manual does show it already installed from Elecraft.


The latest assembly manual, from the web site, indicates that you will 
still need the PA Jumper Block to do some initial testing before 
installing the KPA3.


So, I am trying to get clarification as to whether I really need it.  
And, if I do, I need to get someone to ship me one.


As an aside, it sure would be nice to know what changed from manual 
revision to revision.  That way I could just update the manual that 
came with the kit originally.  In my full-time job, when a procedure is 
changed, there is always a sheet describing what 
paragraphs/sentences/pages were changed.  That makes it easy to see 
where the differences exist.

RE: [Elecraft] K3 Calibration Problem

[Sanger, Joseph]

I am trying to perform the Ref Oscillator Calibration for my 1 ppm
device:


Method 3 (1 ppm TCXO Option):

* Locate the CONFIG:REF CAL menu entry.  Tap 1 to change the name to REF
xxC.

* Locate the calibration data sheet, which shows frequency vs.
temperature over a wide range.

* For each data point, tap 2 or 3 to select the calibration temperature,
then use VFO A to set the specified oscillator frequency in Hz.

 
and am getting nowhere fast.  In step 1, I see the 'REF CAL' menu
displayed by VFO B, but tapping '1' doesn't change the name off the
menu; it merely performs the usual 'tap' function of that switch:  A/B.


Thanks for any help from anyone!

RE: [Elecraft] Elecraft K3 Support on the Weekends?

[Ed Muns]

Install the KPAIO3.  Either it or the simple jumper that is usually there
will allow you to run the K3 without the KPA3 installed for the initial
tests.  With the KPAIO3 (only), set CONFIG:KPA3 to 'PAio nor'.  During
installation of the KPA3, you will change this CONFIG:KPA3 setting a few
times, eventually ending up with it at 'KPA3 nor'.

I found that I did not really miss this at all, firstly the K3 has a
nice bright LED that comes on as soon as you are no longer listening on
the TX frequency, this is much more useful than a simple Split
indicator.

Secondly my logging software (N1MM logger) displays the RIT offset for
me at all times, I do most of my looking at the Computer not the rig
when contesting. 

I do find that split is implemented very nicely on the K3 and recently I
have been using that where in the past i might have used RIT.
I can however see how under some situations where a full time RIT
display will be useful.

I was quiet happy with the K3 in this area as it currently stands, My
ears are the final judge on any filter setting however the K3 roofing
filter / graphic combination is quite intuitive. To me the actual
numbers don't matter, it's hearing the other guy that counts. However I
never looked at the actual numbers on the icoms either.

I am not sure why this would be important to have on display? The only
thing that matters is the power going to the antenna, for this I have an
LP-100. 
However My amp requires roughly the same amount of drive on all bands
and the primary reason for tweaking power is to stay within our 400W
limit
Nudging the power control only moves the power by a small fraction of
1dB so this is as easy a way as any to check what the radio is set to.
there is no way that the other end will ever be able to tell that you
have gone from 70 to 69 watts to check your current setting. 
The 7800 gives no real indication of output power either, just a %
indicator, the K3 does the same on the SMeter in any case.


I suppose what I am really saying here is that I am not finding issues
with the User interface choices that have been made by elecraft with the
K3 to make everything fit on the front panel.There is not a single thing
I miss about the user interface on the 7800. 
(some may say the bandscope on the 7800 is lovely! however I am using
the SDR14 on the IF out of the K3 and it's by far the best bandscope
solution I have ever used.)

RE: [Elecraft] Elecraft K3 Support on the Weekends?

[Simon Lewis]

Henry

I would install the PAIO board that's in the 100w pa kit and use that by
setting the right setting in the menu PAIO normal setting under the KPA
config item - That should work as intended but with no PA installed and
allow your basic tests

The PA jumper is only needed if the 100w pa is not installed and no PAIO
board is available as far as I can see.

I think you should not have any issue doing that and it would work fine

Re: [Elecraft] K2 Bargraph

[Don Wilhelm]

Robert,

Looking at the schematic, the only signal that seems to be unique to the 
bargraph is SR WRT.
It starts on Control Board U6 pin 34 and goes to P2 pin 15.  If it goes 
anywhere else, I did not spot it on the schematic.  Check the U6 socket 
pin and the connector pin for proper soldering. 
Since your control board in the working K2 produced the same symptoms, 
then yes, the problem is likely on your control board.


Check also for solder bridges caused by too much solder.

Re: [Elecraft] roofing filter confusion

[Bill W5WVO]

Speaking of roofing filters and DR3... I was browsing through the spec sheet 
of the relatively new Hilberling PT-8000 "super-rig" yesterday, just to see 
how it compares. This very impressive transceiver sells right now for around 
15,000 USD. It uses conventional up-conversion to a 1st IF frequency of ~70 
MHz, but splurges for a 2.7 kHz roofing filter at that frequency -- not an 
easy (or inexpensive) thing to do. As a result, its claimed numbers are about 
as good as it gets for this kind of receiver design.


But compare with the K3, with its ~8 MHz 1st IF, at a cost (fully loaded) of 
about 3,000 USD:


IMD3 dynamic range
at 2 kHz spacing: PT-8000 86 dB, K3 95 dB
at 5 kHz spacing: PT-8000 97 dB, K3 100+ dB

Because of its 70 MHz 1st IF, a 500 kHz or 200 kHz roofing filter (as in the 
K3) is out of the question. And that 9 dB difference is significant. Suppose a 
guy a couple kHz up from you running 100W is S9+40 on his own frequency, but 
is causing no problems for your K3 copying a very weak signal 2 kHz down from 
him. That same guy, if you were using the PT-8000 receiver, might have to QRP 
down to as little as 12 watts in order not to cause IMD problems for you, all 
other parameters being equal, or QSY up the band another 3 kHz or so --  
neither of which is very likely.


I don't expect my K3 until some time in February or March, but I'm sure 
looking forward to it.  :-)  It will be a long wait. I'm really enjoying the 
reports you guys are sending in as you receive yours and put them through 
their paces.


And you 6M guys, don't forget the winter Es season should be starting any day 
now! Check the band out often, especially during early evenings, when winter 
Es is more likely to occur.

The Orion has a

famous flaw where it switches in an amplifier to compensate for
losses in the 500 Hz and 250 Hz roofing filters, but the gain is too

Dick I believe the flaw in Orion was actually routing the
signal first through the 20 kHz roofing filter plus following
12 dB amplifier before the 500/250 Hz filter and the second 12
dB amplifier.  IMD products were generated prior to reaching
the narrow filter stage...similar to the problems up-conversion
rigs have using 15-20 kHz roofing filters.


Hopefully, variable gain will compensate for losses with no other
distorting

effects. But even if it does, what's to be gained by using an 8-pole
filter in the first place? Can it be demonstrated that the 8-pole
filters improve selectivity beyond what the IF DSP does? Have tests
been run to determine specific gain settings for each filter offered
by Elecraft so dynamic range won't be compromised?

As can be seen in the following IMD performance, the 8 and
5-pole filters have similar performance (at similar bandwidths):

Filter20kHz  10kHz  5kHz  2kHz

Gain compensation for the K3's 8-pole filters is set in the DSP stage
according to individual insertion loss measurements supplied with each
filter, per the filter installation procedure.  Orion's gain
compensation for the 250/500 Hz filters was set much earlier in the
IF chain which led to the problems with those filters.  There were no
corresponding problems with the 1.8 kHz 8-pole in Orion because its
insertion loss was low enough not to need additional compensation.

Regarding possible advantages of 8-poles versus 5-poles,
Elecraft claims the 8-pole may have better BDR performance, but I
suspect any such theoretical advantage would be overridden by
transmitted signal issues such as key clicks, phase noise, etc.

Any filter will produce "ringing" when the bandwidth is too small.

Ringing is a function of the bandwidth and only affected by the type
of filter. In some filter designs it's possible for some elements of
the filter to have such a high Q they ring even though the overall
filter bandpass is not that small, but that's a aberration in the
filter design.

Ringing typically occurs when the bandwidth at either the transmitter
or receiver is restricted too much to allow the CW sidebands to pass
through.

Of course, the sidebands on a CW signal are the frequencies
represented by the rise and fall of each CW element. If the bandwidth
isn't sufficient to pass them, the element is stretched out in time
as the amplitude decays, just like the amplitude of a bell decays
after the bell was stuck. That's what we call "ringing".

For the same passband ripple and bandwidth I think more poles pretty
much invariably means more ringing.

By the way, many people think that DSP-based filters don't ring.
Actually, a digital filter's impulse response, measured at say the
half-power point, is pretty comparable to an analog (e.g. cyrstal)
filter with the same ripple and bandwidth.  However, the ringing from
a digital FIR (finite impulse response) filter eventually drops all
the way to zero, while an IIR (e.g. analog) filter theoretically
rings forever.  Since human sound perception tends to be logarithmic,
the ringing _sounds_ longer with the analog filter.

[Elecraft] resale value and low serial numbers

[Eric]

Hi all,


Why did I plunk down money for a low serial number? For a better 
resale value? No way, I did this because I wanted to be able to use 
the new K3 as soon as possible. Also  I trust those guys to develop 
the latest and greatest radio in ham radio today and prepayment 
enabled Elecraft to start production and to do a huge investment in 
hardware and software development  which might otherwise never happen.


Resale value  never came up to my mind.

BTW I owned a mint high SN Collins 75S3C,   collector's item, but I 
sold it. This Collins may have the market monetary value of a 
standard K3, but the K3 is radio wise way ahead in every imaginable spec.

And there you have it. The thread has finally looped back to the funny point
I was making when I originally brought this up. :-)

I wasn't complaining about the low resale value of my low s/n K3. I was
answering a question about why I LIKED having a low s/n K3 and felt I needed
some negatives to throw in there. So I made the same joke Thom just did;
that my low s/n K3 will eventually have less resale value than a more recent
K3, but it won't matter as I'll be dead -- implying, of course, that I don't
intend to ever sell the radio, so even my contrived "negative" is not a
negative at all.

Ah, these things are always so much funnier after they've been taken off in
another direction and you get a chance to explain the joke line by line. :-)

RE: [Elecraft] Elecraft K3 Support on the Weekends?

[Ron D'Eau Claire]

Ed and Simon have it right. You can continue on, as they said, installing
the KPIO3 and selecting KPAio nor in CONFIG:KPA.

There *should* have been a jumper block pre-installed in case you were
building a low power K3. It's required in a low-power K3 to complete the RF
circuit when there's no KPA3 module. 

Even with the KPA3 option Wayne wants you to do the tests and calibration
procedures shown before putting the KPA3 itself into the K3. That's why the
manual says to leave the jumper block in until those procedures are done.

The KPIO3 board that mounts in place of the KPA3 (and the KPA3 100 watt
module plugs into it) has a relay than handles bypassing the KPA3 for low
power operation or routing RF through the KPA3 for high power operation. It
will function as the "jumper block" when KPAio nor is selected.

Ron AC7AC

  
-Original Message-

I would install the PAIO board that's in the 100w pa kit and use that by
setting the right setting in the menu PAIO normal setting under the KPA
config item - That should work as intended but with no PA installed and
allow your basic tests

The PA jumper is only needed if the 100w pa is not installed and no PAIO
board is available as far as I can see.

I think you should not have any issue doing that and it would work fine

That was about the time it was decided to remove the covers in Aptos to

Likely yours had one corner "dog-eared" so it was obvious and easy to
remove. At least that was the plan at one point. Then it was decided nothing
was gained by leaving them in place and it was just as easy to remove the
cover completely as it was to make sure it was obvious to the builder.

[Elecraft] K3: PSK31 use case

[Matt Zilmer]

All,

I have reached the conclusion that the K3 may be the best data radio
I've ever owned or operated.  Got plenty of compliments on the audio
quality (no IMD or wide-bandwidth products).  The folks I worked -
most of them had heard of or seen the K3 [hamfests], and two of the
guys wanted their own after hearing this one.

My set up here is pretty plain so far, but I had a whale of a good
time operating low power PSK on 20m today.  

Did some experimentation before going live, and set up things as
follows.  The MON and TEST functions really help with getting levels
right.

Data MD:  Data A

TX line in setting:  20% of full scale.  The output is a laptop's
speaker jack and the setting reflects the playback volume set on the
laptop.

RX line out setting:  55% of full scale.  The input is the mic jack of
the laptop.

RX Filter:  shift it to 1 KHz Fc, and 200 to 400 Hz bandwidth.

K3 Line In Gain:  set at 5 to 10.  This range seems fine, but it won't
help to go any higher than 8 or so.

K3 Line Out Gain:  leave this at the default 30 setting.  It works
fine.

K3 Mic Source:  Select Line In.  Don't forget to put it back when you
return to voice modes.

PTT-Key:  I ran it DTR-Off, but you could also use RTS for keying.

Set up at the home QTH is as follows-
K3/10
MFJ-941 tuner
Long wire antenna - 130' long at 35' above ground.
Two stereo cables - 3.5mm to 3.5mm, both male
USB:  Keyspan USA-19HS serial port adapter @ 38400 bps.
SW:  Digipan 2.0 running on XP Pro, SP2.

I had a power setting of between 3 and 5 Watts.  With PSK31, that's
enough.

73,

RE: [Elecraft] Elecraft K3 Support on the Weekends?

[Ron D'Eau Claire]

While most revisions to a new letter involve incorporating the items shown
in the errata, there was an additional major change made between Rev B and
Rev C of the K3 Kit Assembly Manual. 

The procedure was reorganized to allow builders with the KPA3 100 watt
amplifier module to install the KPA3 shield assembly during the initial
build. That avoids removing the bottom covers and KNB3 module and standoff
later to install the shield. New steps were added to actually install the
shield, a number of existing steps were moved to put them in the most
convenient order. 

Almost every page in the assembly procedure was changed in order to
accomplish that.

Re: [Elecraft] Elecraft K3 Support on the Weekends?

[k4tmc]

So... I am wasting my time trying to build my K3 with the Assembly 
Manual (Rev B-1) that came in the box!


I really did not want to throw away the manual that came in the box, 
but it apparently is of little value now.


I am now stopping work and printing a new manual.

73,
Henry - K4TMC
(while its printing I think I'll go kick the dog)

While most revisions to a new letter involve incorporating the items 
shown
in the errata, there was an additional major change made between Rev B 
and

Rev C of the K3 Kit Assembly Manual.

The procedure was reorganized to allow builders with the KPA3 100 watt
amplifier module to install the KPA3 shield assembly during the initial
build. That avoids removing the bottom covers and KNB3 module and 
standoff
later to install the shield. New steps were added to actually install 
the

shield, a number of existing steps were moved to put them in the most
convenient order.

Almost every page in the assembly procedure was changed in order to
accomplish that.

As an aside, it sure would be nice to know what changed from manual
revision to revision.  That way I could just update the manual that
came with the kit originally.  In my full-time job, when a procedure 

is

changed, there is always a sheet describing what
paragraphs/sentences/pages were changed.  That makes it easy to see
where the differences exist.

Go to the web site and download the errata for the manuals in question 
is

how I would find out.

Re: [Elecraft] K3 filters

DSP makes very steep  filters WIHOUT group delays.
K3 concentrates best selectivity here. Correct!

I think you meant that they don't have group delay variations.  They 
certainly have group delays; they work by adding together delayed 
versions of the signal.


Actually I have a feeling that constant group delay is only true of 
finite impulse response filters.

[Elecraft] K2: Very low output on 160m

[Ken Alexander]

Hi All,

As usual, I decide to do something new with my K2
during a contest!  I'll never learn!

Tonight, I'm trying 160m for the first time.  Before I
go any further, I should mention that my K2 receives
extremely well on 160.  However, when I hit the Tune
button to send some RF to my autotuner and get it
tuning, the indicated output is 0.3 Watts even though
the Power knob is set to 10 Watts.  An external
wattmeter confirms this.

I replaced the antenna with a dummy load and got the
same result.  RANT is set to OFF in case you're
wondering.

There doesn't seem to be a Troubleshooting section in
the K160RX manual so I'm at a loss to know what to
look at.  Any help would be appreciated.

Thanks and 73,

Ken Alexander

[Elecraft] K3 performance excels

[K4IA]

I've been listening in the 160 contest to see  how the K3 does in some really 
horrific conditions.  Lots of very loud  stations with awful key clicks 
crowded in a small area would crush the front end  of most receivers.

I have the 500 hz roofing filter.  I can easily  get within 200 hz of a very 
loud and clicky signal and still copy a weak  station.  There is no pumping of 
the AGC to cover the little  guy.   A station 500 hz away simply disappears.

On SSB, I have  found I can cut the bandwidth down to 1.5 khz  or below and 
by moving the  passband 1.30 khz, I can copy the signal.  It is pinched but 
very easy to  understand.

The K3 is very impressive.
