You can save configurations for "his" and "her" right now with the K3
Utility.


I'm aware of that option, but would only regard it as a temporary 
workaround. Connecting a computer and reconfiguring the whole rig is not 
the right way to handle a routine change of operators.

[Elecraft] K2 noise blanker

[Stephen Prior]

Many thanks for all the suggestions!  Since it is easier and quicker to take
the radio to a dimmer switch than it is to remove the covers and scratch the
top of a transistor, I shall do that first!

I am beginning to think that I was expecting too much from the circuit, and
that being elecraft it would somehow squeeze the laws of physics a bit!

Re: [Elecraft] how does the fan work in the KPA100

[Don Wilhelm]

Werner,

As far as I know, there is only one temperature trigger point for the 
fan operation.

For most CW/SSB operation, the Fan Normal will do just great.
If one is operating digital modes or in intense contest situations, the 
Fan Hi/Lo setting may be best so that the fan normally runs at low speed 
and increases when the temperature reaches the trigger point.
For really intense operation in high ambient temperatures and/or 
situations where the noise of the small fan is objectionable, an 
external muffin fan mounted above the heat sink can provide extra 
cooling and in most cases will keep the internal fan from coming on.  
Take a look at www.n0ss.net for some pictures of Tom's external fan 
implementation.

Like this it is off when I switch the amplifier on. 
It goes to fast when I operate for a certain time with high power and the 
heatsink gets hot.

But I did not see a low speed operation of the fan in this mode.

When I switch to low/high, it always runs at low speed and probably switches 
to high when necessary.


Is it correct that there is only one temperature trigger point?

[Elecraft] Re: K3 - qsk keying loop

[Don Rasmussen]

[Elecraft] Re: K3 - qsk keying loop
Dick Green WC1M wc1m at msn.com 

Hi Dick,

Happily, the K3 is modular. Would I be incorrect to
assume that a hardware solution could be engineered to
perform this specific purpose, and reasonably
inexpensively?

All it would really take would be for Eric and Wayne
to buy into the idea of it's importance. I don't see
them sticking their jaw out about this issue simply
out of principle (like some others made a mistake of
doing in the past?) 

Part of Elecraft's larger difficulty at this time
involves the fact that they have created a transceiver
that will appeal to a wide variety of interests.

Contesters, CW ragchewers (me), AM, FM, Digital, ESSB,
SWL, even transverter fanatics. 

They have released a very fine base model K3, which I
feel will be accepted very well, however they still
have to get the subreceiver integrated into the
firmware and release that bit of hardware and I expect
that is bigger on the list of to do's than the keying
loop - just my guess.

There are also other larger issues behind that like AM
and FM support (advertised), maybe some transverter
issues, and variable roofing filters.

There is a lot in competition for these guys attention
and it will be interesting to find out how the voting
is done with respect to everyone that wants everything
in their own diverse interest.

As a part time contester, given the fact that there
are acceptable methods of getting the switching done,
I'd like to see some features that are not there at
all added, before making something that is already
there a little better.

And I understand that a true contester would fight me
to the grave over this one issue, but we both pay our
money and take the best we can get. 

As a general operator, I've been pushing hard to get
some kind of single press band switching in the
firmware, which is pretty meaningless to a contester
that is allowing the program in his computer program
to do all that. 

Anyway, I know the radio was primarily focused towards
contesting from the beginning and maybe it would have
been icing on the cake to have the switching done a
backwards compatible way on top of all the other good
stuff, but most likely at the expense of some other
things that would not have made it into the radio.
Some things are still waiting (like ESSB or AM) to be
fully implemented.

Darn I wish I had an amp to be concerned about, and it
won't ever happen at this QTH, but the guys still have
a transceiver that you have your eyes on and I have on
order already so I suppose that's fair enough for now.

I understand that there's a software utility that allows you to save/load
configurations to/from a computer. But it would be handy if it were possible
to save and restore a small number (somewhere from 1 to 4) of configurations
in the radio itself. You could accommodate different operator preferences at

Having the ability to quickly and easily get a complicated system back to a

Re: [Elecraft] K2 Noise blanker- is it working?

[Don Wilhelm]

Stephen,

Turn the preamp on and scratch/tap the Q21 case with a metallic object 
(screwdriver) while turning the NB on and off.  If the NB is working, 
you will hear the sharp impulse clicks substantially reduced.


Many types of power line noise are not handled by the KNB2, it is great 
on impulse noise, such as that from an automobile engine (not diesel).  
The KDSP2 does a good job on many other types of noise.

It is said that it works against the sort of pulse noise I get here from

is that you can usually hear some change when it is switched in, but I
don't.

Am I expecting too much?  Or could there possibly be a fault which would

had I not made it myself, I probably would not be asking the question!

Re: [Elecraft] K3 2nd run priority via-a-vis deposit

[Mike B]

This had always been my understanding of the system.  I'm in the 2nd run, and
didn't put in a deposit at that time because, 1) I knew I wouldn't get the rig
any faster, and 2) I just wanted to hang onto my money for a little longer ;-)

I think a lot of the problem has been too many posters early on stating their
misimpressions as facts about the ordering process.  These fallacies just
continued to grow over time, taking on a life of their own.

Last week, we just saw how one email was misinterpreted by several here as
showing a rig had been shipped out of order.  Tempers & emails flew, when there
was no need for it.  I trust Wayne, Eric & the crew to make the finest rigs for
 the money, and in nearly 10 years, I've come to trust their business practices
as well.  They & their crew will do their best to get the rigs out the door as
quickly as possible, as close to order priority as possible.

While everyone would like the K3s to be moving out the door faster (including
everyone at Elecraft, I'm sure), continued public complaining about the
unchangeable process does no one any good.

Re: [Elecraft] K3 2nd run priority via-a-vis deposit

[Eric Swartz - WA6HHQ, Elecraft]

Hi Doug,

We were taking great pains -not- to give this impression at Dayton, 
since we were already into the 2nd run. I apologize if there was 
confusion on this issue.


I am very clear on this and made sure we kept everyone informed of what 
we were doing. Prior to Dayton we had already changed the web order form 
to reflect this change and we had also noted from the first day of 
orders that deposit priority for low serial numbers -only- applied to 
the first run numerous times on the reflector.


We absolutely did not want to penalize those who ordered during the 
first run without deposits. If we had continued moving later orders with 
deposits (received after the first run was full around May 14th) ahead 
of the earlier orders received -without- deposits, those early 
deposit-less orders would have been bumped well into next year. Not a 
fair thing for those people. Basically we took orders, both with and 
without deposits, until we filled the first production run. At that 
point we set up that groups to ship first from the deposit group and 
then from the non-deposit group. After that, all orders will be shipped 
in order received.


A side note - All deposits are always refundable (though we take a 3% 
hit from the CC company on each one.) We will gladly refund a deposit to 
anyone who asks.

Yes, it does seem that the rules changed somewhere in mid-stream (an
unannounced change).  I know that I am not the only one who felt this
way because others who ordered at Dayton and did not place a deposit
felt that having to wait until the "end of the run" was fine with
them.

I suppose that this entire concept never made a whole lot of sense to
me because "why should Run #1 guys w/o a deposit receive priority over
Run #2 guys who did include a desposit?"  Now I know why I was
confused about that "logic"because those of us ordered at Dayton
were operating under an incorrect pretense.

[Elecraft] Re: K3 - qsk keying loop

[Dick Green WC1M]

Pardon me for jumping in here. I don't have a K3 and don't have one on
order. I'm trying to make that decision. I've read a lot of good things
about the K3. Absence of a keying loop isn't one of them.

 

Although it's true that some modern QSK amps may appear to work fine without
a keying loop, bear in mind that both Acom and Ten-Tec recommend using them.
Elecraft should consider the recommendations of the amp manufacturers, not
what they *think* will work correctly. Even if Elecraft is right, why force
the owner of a $6,000+ amplifier to go against the manufacturer's stated
recommendation? If something goes wrong with the amp's T/R relay, causing an
expensive ship/repair/ship drama, will Elecraft indemnify the owner?
Probably not. I sure wouldn't want to get in the middle of that
finger-pointing exercise.

 

Alpha 87A owners can relax: Alpha specifically discourages use of the 87A
keying loop. That's not surprising, because the keying loop logic in that
amp doesn't work correctly. It's not a problem because the PIN diodes switch
almost instantaneously and there are no mechanical contacts to burn. You can
drive that amp all day with the PTT output line. And that's what Alpha tells
you to do.

 

Let's look a little closer. The typical Jennings and Kilovac type vacuum
relays used in QSK amps have rated switching times in the  6-8ms range. In
some designs, the relay is triggered with a burst of high voltage which
reduces the switching time to as little as 2ms. So, theoretically, there's
no danger of hot switching if the transceiver has a delay between PTT and
the start of the RF envelope of, say, 15 ms. But the problem is that you may
not know what else the amp is doing besides closing its vacuum relay. For
example, the Acom 2000a has a rather complex T/R switching sequence that
involves several relays, and the timing may be longer if the amp has to
retune. My point is that you can never be sure exactly what timing
constraints a QSK amp may impose, so it's best to follow the manufacturer's
recommendation and let the amp decide when it's safe to apply RF. In other
words, use a keying loop if the manufacturer says to.

 

In theory, relying on the transceiver to delay RF can reduce the maximum QSK
speed (i.e., compromise the ability to hear between code elements.) But
that's only true if the transceiver's delay can be reduced to less than the
amp's switching time. If the delay isn't adjustable, then the excess delay
will be present whether a keying loop is used or not. The best setup is a
keying loop with a fully configurable PTT delay. At any rate, I can't attest
to the effect of an extra 10ms or so of receiver muting at high speeds. The
QSK experts will have to comment on that.

 

A keying loop is also very desirable for preventing hot switching of antenna
relays. A TX ENA or TX INH port can be used to suppress RF before and during
any switching. It's possible to use PTT to prevent switching from taking
place, but it's not as foolproof as suppressing RF -- there are timing
windows where hot switching can occur. Also, if you use PC-based software to
do your switching, it's a heck of a lot more difficult to detect when PTT
has been closed than it is to raise TX INH. My point  is that many contest
stations, including mine, have switching systems based on the
commonly-available keying loops found on popular rigs. Why force us to give
up or modify those hard-won systems?

 

This leads me to the key question: Why not implement a standard feature that
the amateur community has come to rely on? After all, you wouldn't want to
get a reputation of ignoring such things, like a certain other US-based
manufacturer of amateur transceivers :-)

 

I think it's unfortunate that Elecraft has made the decision to omit a
keying loop. They may not have realized that the K3 is going to appeal to a
whole different breed of users than the K2, including contesters who have a
wide variety of equipment, station configurations and very demanding
requirements. Lack of this feature is going to complicate my buying
decision, for sure. But I'm always willing to resort to a mod if I have to
(Warranty? What warranty?) Is there a point in the circuit where it would be
possible to safely implement a TX INH or TX ENA function? If so, my
soldering iron is heating up. ? If not, I hope K3 will reconsider a keying
loop for the next major rev.

Re: [Elecraft] K3 SSB Bandwidth at this Time?

[Greg - AB7R]

Hi Dave,

Right now the TX BW is limited by the 2.7 or 2.8 kHz roofing filter and 
firmware.  This IS 
on the list and moving up rapidly.  While I cannot say for sure when it will be 
available 
with certainty, I would still go ahead with the 6.0 kHz filter.  There's a 
reasonable 
chance it may be available by the time you get your radio or shortly after.

Sorry, I'm a Pascal man.

Lazarus is based on Free Pascal. It can create code for a lot of
current platforms, the main issue is the UI libraries which have not
been fully implemented on most of them. The best supported are Windows
and Linux. Mac OS and Pocket PCs (ARM processors) are also usable,
apparently

My UI would need some redesign to fit on a pocket PC screen. But
potentially it's possible. You could communicate with the K3 via a
Bluetooth serial adapter and have a pocket sized Morse and PSK
terminal...

[Elecraft] K3 SSB Bandwidth at this Time?

[David and Dianne on Comcast]

Hi Everyone,

As I wait for my K3 order to be filled in the next few weeks I have a 
question concerning the currently available SSB bandwidth in the K3.


I have initially ordered a 6.0 roofing filter thinking that it will be 
required for a somewhat wider SSB bandwidth in the range of 3.0-3.2 that 
I prefer.


Not really ESSB but wider than most stock SSB bandwidths in most 
transceivers.


I see in the owner's manual errata sheet that ESSB is a feature for the 
future.  So I need to decide if it make sense to order the 6.0 filter if 
TX SSB bandwidth is not available above 2.8 at this time.


Does any one know what the maximum transmitted bandwidth of SSB 
currently is in the K3?


Does anyone know how far away ESSB TX is as an added feature?

No big deal but I am curious.

Tnx and 73 de N1LQ-Dave

[Elecraft] K3 - qsk keying loop

[Phil & Debbie Salas]

"Over the past decade I've used a slew of Ten-Tec and Yaesu xcvrs interfaced
to Ten-Tec, Alpha, and Acom amplifiers via plug 'n play keying loops with
uniformly excellent performance.  The lack of QRO QSK with the K3 may be a
big issue with some prospective K3 contesters."

I disagree that this is a problem.  The new TenTec Orion and Omni VII
transceivers have a minimum "amp-key to RF out" delay of 15ms.  The Kenwood
TS480 and TS2000 have a minimum delay of 10ms.  My Yaesu MKV has an
adjustable delay of 0-30ms (5ms default).  I measured the delay on my
IC-706MKIIG at 15ms, and on a IC-7000 at 10ms.  If you have a QSK amp, it
will switch at least within 10ms if it uses high speed signal relays,
probably around 3-6ms with vacuum relays, and maybe 1-2ms if it uses PIN
diodes.  Both the THP and SPE solid-state amps switch in 7-10ms using high
speed relays.  So all you have to do is to adjust your K3 delay to something
longer than the amplifier relay switching time. If you have any doubts, set
it to 10ms and you should be fine. 

You can hear where the delay needs to be set by listening to your signal on
a second receiver.  I experimented with this using my Yaesu MKV and my
QSK-modified Ameritron ALS-600.  The relays in my modified ALS-600 switch in
3ms (measured with a 'scope).  But just for the heck of it, I listened to my
signal on a second receiver while I shortened the delay time on my MKV, and
I started hearing key clicks in the receiver right around 3ms (just like my
measurements had predicted).  So I just re-set my MKV to 5ms delay and
everything worked fine.  I had to set the delay on my MKV to 10ms when I was
testing the THP and SPE amps to stop the clicks.

[Elecraft] how does the fan work in the KPA100

[Dr. Werner Furlan]

here I am again with my next question. 

I don't understand how the fan should work in my KPA100.
I have set the fan to normal in the K2 PA menue. 
Like this it is off when I switch the amplifier on. 
It goes to fast when I operate for a certain time with high power and the 
heatsink gets hot.
But I did not see a low speed operation of the fan in this mode.

When I switch to low/high, it always runs at low speed and probably switches 
to high when necessary.

Is it correct that there is only one temperature trigger point?
>From reading the bias setting part of the manual, I thought the fan should 
run at low speed also when I switch the PA into high power mode.

Is it correct how it works here?

thank you for the very clear explanation. In the moment (and I think it is 
usually like this) the only band where the noise floor with the antenna is not 
higher than without antenna is 10m. Without knowing much or thinking about 
it I did the same as you, I only used the preamp when the band is very quiet.

[Elecraft] K2 Noise blanker- is it working?

[Stephen Prior]

I built the noise blanker kit for my K2 s/no. 4905 (I think) a few weeks
back, and I am beginning to wonder if it is working.  I can not tell any
difference between NB1, NB2, whether hi or lo threshold.

It is said that it works against the sort of pulse noise I get here from
power lines occasionally, yet it makes no difference.  Since all the cars in
the family are diesel powered and I am some distance from a quiet country
road, I have not had the opportunity to see whether it works on petrol
engined ignition noise.  My experience with noise blankers in other radios
is that you can usually hear some change when it is switched in, but I
don't.

Am I expecting too much?  Or could there possibly be a fault which would
still pass the rx signal through the noise blanker board and yet stop the
noise blanker working?  Had I not read how good it is supposed to be, and
had I not made it myself, I probably would not be asking the question!

Thanks

[Elecraft] K3/100 #095 Kit

[Gary Bartlett VE1RGB]

Kit K3/100 #095 is now here in Halifax, for those who are tracking this kind 
of info.  Almost certainly the first in NS, maybe in all of the Maritime 
Provinces.  This is a fully-loaded unit (second RX to come) that was ordered 
on 30 Apr, shipped from Elecraft circa 20 November, then captured and held 
for ransom by Canada Border Services Agency (not Elecraft's fault) who 
thought I  was some kind of commercial outfit and sent me the most 
intimidating and difficult-to-read piece of paper [Form B3-(04) - two 
copies, please] that I can remember in all my 63 years.  That cost me a week 
or so delay while I sorted out the bureaucracy.


Now, with trembling hands, on to the kit inventory...

There are good fundamental technical reasons why the KX1 doesn't cover 17m and 
15m.

The DDS frequency generating chip in the KX1 is the AD9834.  When the KX1 was 
introduced several years ago, the AD9834 had a maximum rated clock frequency of 
50 MHz, which is used in the KX1.  The maximum usable clean frequency generated 
by any DDS is one-third the DDS clock.  Thus, the highest usable frequency from 
the KX1 DDS is 16.67 MHz.  That doesn't support operation on 17m, much less 
15m.  The highest frequency required for the receiver local oscillator to 
support both USB and LSB reception is the operating frequency plus the IF 
frequency (4.915 MHz).  For 21.45 MHz operation, a DDS output of 21.45 plus 
4.915 MHz (26.365 MHz) is required.

Late versions of the AD9834 are rated for a 75 MHz clock, but even that doesn't 
support generation of DDS output frequencies higher than 25 MHz.

A non-trivial re-work of KX1 hardware to change the clock and the DDS type 
would be necessary to support operation on the 15m and 17m bands, in addition 
to various firmware and RF circuit revisions and additions.  A new little RF 
circuit board similar to a KB3080 that could be added to existing KX1 units 
wouldn't be sufficient.

Availability of 15m operation is one of the several reasons the good old K1 is 
my favorite QRP rig of all time.

Re: [Elecraft] Online Orders: both international USPS options, were not valid

[Larry Phipps]

Depending on country, you can purchase more insurance than the USPS 
internet store allows by going to the Post Office. For some reason, they 
need to see the package if it has high insurance. Probably because 
someone ran a scam somewhere, sometime. Priority Mail is more limited in 
its insurance options unless you live near a major city. Express Mail is 
generally a good bet. Express Mail Guaranteed is actually handled by 
Fedex and is much more expensive. FWIW, I send lots of packages to 
Europe and have never had to file a claim... but I always buy insurance

From what I understand from discussions that may have been off-list,

USPS options are not allowed for international K3 orders because the
maximum insured value is not great enough.

Re: [Elecraft] K2 / 100 - SSB Filters

[Don Wilhelm]

David,

It may help for you to re-visit the FL2 and FL3 filters with 
Spectrogram.  Instead of believing the filter widths that are indicated 
on the display, you may want to actually measure the width in the 
Spectrogram display.  When the K2 variable filter is set substantially 
away from its design point, the filter width does not track very well - 
the design point of the K2 variable filter is in the 400 to 600 Hz 
range, and a width of 2kHz is very far away indeed.  Usually the actual 
width is wider than that indicated.


If you need additional information about setting the SSB filters, take a 
look at my website www.qsl.net/w3fpr - look at part 3 of the article on 
K2 dial calibration.

Re: [Elecraft] K3 - qsk keying loop

[Brendan Minish]

Folks,

For what it's worth, My QSK amp is an Acom 1000, With the K2 and now
with the K3 I have never ever had it hot key or clip Dits. 
With My old Icom pro2 I had hot keying issues until I started using the
solid state keying output (it's faster than the relay driven output)   

None of my Icoms ever had a QSK keying loop as far as I am aware either,
perhaps it's a Ten-Tec thing

With the K3 I simply plugged it in and got on air. Full QSK with the
Acom 1000 in line is every bit as wonderful as the K3's full QSK
barefoot.
The K3 also has a PTT line, which with the footswich in my setup works
perfectly for overriding QSK when required 

I would have thought that with any amp design, no matter how fast or
slow, each amp will have it's time constant.For slower 'qsk' Amps Surely
it's simply a matter of measuring this time constant and applying it as
the time delay?

If you absolutely have to have a QSK keying loop the presence of the
separate PTT line makes it possible to engineer a simple external
solution

Could be, although I've used Alpha 87As with each of my K3s in SS CW and
many other CW contests, full bore QSK, for four months now.  KEY OUT from
the K3 to the 87A has worked great, as far as I can tell.

There is a delay built into the K3's amplifier keying output, both 
before RF is produced and after it stops. Perhaps all Elecraft needs to 
do is publish this specification and it will be possible for you to feel 
more comfortable. I have used the K2, which has about 15 ms pre-RF delay 
 and adjustable after-RF hold with homebrew and modified amplifiers 
that use vacuum relays as well as an Alpha with PIN diodes, and in all 
cases there has been no hot switching (checked with a scope).


The K3's "semi-QSK" setting allows you to adjust the hold time from the 
same as "full QSK" to a much longer delay than you will need. So as long 
as the pre-RF delay is long enough, you should have no problems.


In my opinion, keying loops add unnecessary complication.

Re: [Elecraft] K3 - qsk keying loop

[Eric Swartz - WA6HHQ Elecraft]

Hi Barry,

There is a lot of confusion and mis-information about the need for CW 
keying loop feedback from the amplifier to the rig in the amateur 
community. While certainly it was necessary on some older rig and amp 
combinations, it is not necessary with a properly designed rig today 
that has sequenced amplifier key-out to RF output. As an example, I run 
both my K2 and K3 in full break-in with my Alpha 87a amplifier with no 
timing problems or reduction in break-in performance.  A large number of 
our customers run full break-in with our rigs in this manner using a 
wide range of full break-in amplifiers. There is no degradation of rig 
break-in performance when using the K2 or K3 in this manner. A large 
number of our K3 Field Testers are break-in CW ops with amplifiers and 
none have had any issues with running our rigs with their amps.


I think that since some are used to using a keying feedback loop on 
other rigs and amps that it is necessary on all. I guess I disagree :-) 
. RF sensing in the AMP is absolutely not needed with proper key-out to 
RF sequencing from the rig. And excessive delays are -not- needed.


But, if it can be shown that we actually can increase K3 break-in 
performance with an amp by doing something like this, we'll certainly 
look at doing it.

at some point I am relying on the RF sensing circuitry in my QSK amps to hold
the relays closed until RF is really gone from the input. That may work but I
would really prefer the sure-fire solution of a keying loop. This allows a QSK
amp to be set up optimally by just plugging in and does not require a scope
and a bunch of fuss. The QSK of my Tentec transceivers coupled with

never go above 50 wpm anyway.

[Elecraft] 10 (?) Programmable Function Switches

[Alan Bloom]

This isn't meant to be a complaint or anything, but just to make sure I
am reading the manual correctly, do I have this right?

The "10" programmable function switches are actually only 6 physical
switches:  M1-M4 (tap or hold) and PF1-PF2 (hold).  And if you reassign
any of M1-M4 (either tap or hold) you lose the message play function for
that switch.

So in reality, there are only two switches dedicated to programmable
function.  Or more accurately, half of two switches since only the hold
function is available for re-assignment, not tap.

Did I get that right?

Re: [Elecraft] K3 - qsk keying loop

[Allan Taylor]

Don and K3 fans,

I have a few comments on interfacing Elecraft transceivers with QSK amps.

When the K2 was first announced publicly (Oct 1999, Pacificon QRP forum)
Wayne and Eric invited those attending to give input and comments
regarding desired features. As I have been a Tentec fan for many years and own
two Tentec QSK amps, I requested of Wayne that a QSK keying loop be
provided in the K2 design. As you know, my request was not implemented.
This fall, again at Pacificon, I asked Eric I asked if there would be a QSK
keying loop provided, this time in the K3. His response was in the negative.

Don, in the email below, says that the time delay in the K3 will accommodate
a QSK amp. That is only partially true. The problem is in setting it
up. I could,
of course, put in a LONG delay but then QSK is gone. If I crank the delay down,
at some point I am relying on the RF sensing circuitry in my QSK amps to hold
the relays closed until RF is really gone from the input. That may work but I
would really prefer the sure-fire solution of a keying loop. This allows a QSK
amp to be set up optimally by just plugging in and does not require a scope
and a bunch of fuss. The QSK of my Tentec transceivers coupled with
either the Titan or Hercules II QSK amps is plenty fast for me as I
never go above 50 wpm anyway.

For what it is worth, the Yaesu transceivers and their Quadra QSK amp use a
keying loop. It works great also. We used it in SS this year and had a ball.

I am sure that the K3 will key perfectly with the yet-to-be-available Elecraft
amps, but it would be nice if interfacing with existing QSK amps could be
done in the obvious way.

BTW: I am purchasing a used K2/100 (updated, of course #755) from a
K3 buyer and am on the 3rd run for a K3.

I've already got MixW for that. The ham community probably doesn't

Do you also plan to have a command that would allow software to poll
for packets of decoded text, instead of having it come out the serial
port as an unstructured stream as the TT command now does?

Re: [Elecraft] Thoughts on additional K3 feature

Eric,
Thanks for explaining that. I think being able to send text directly 
will be a very worthwhile feature.  It would be an interesting project 
then to create a simple keyboard-to-serial controller to allow PSK 
operation without the need for a pc.

I thought this was possible using the KY command. You can send CW
using this command, via the serial port even with the K2. Of course,
it would not be very convenient having to type KY commands from the
keyboard instead of just plain text, so a terminal program might not
be the best way to do it.

The KIO3 Programmers Reference manual isn't clear, but it looks as if
you should be able to generate PSK31 or RTTY using the same KY
command, with the radio set to that mode.

In fact, that is really the point of my new program KCommunicate which
I have literally just this minute made available for the first public
upload at http://www.g4ilo.com/kcommunicate.html . With the K3
supporting this facility you could send and receive CW, RTTY or PSK
using nothing but a three wire serial cable between the computer and
the K3. No sound card needed.

For the time being it works with the K2 using the PSK Core DLL to do
sound card PSK31 encoding/decoding. It's also quite good for logging
and CW as well. I made 175 contacts over the weekend in the CQ WW
contest with it. So I will be interested to hear what anyone who tries
it thinks. Especially anyone who tries it with a K3, which is supposed
to use the same K2 commands.

Re: [Elecraft] Thoughts on additional K3 feature

[Greg - AB7R]

Please do NOT attempt to connect a keyboard directly to the K3.  Right now that 
port is ONLY for the boot loader.  

This port may be available for a keyboard in the future, but not now.

I just worked 4U1UN, with only 100 watts and a delta loop antenna, on 14.285

Re: [Elecraft] K3 Curious behavior

[David Ferrington, M0XDF]

I second the vote to move it - I think its something you probably might do
(when I've got my K3 I'll know) once or twice a session - but not enough to
use up one of the prog function keys (I'm waiting for KDVR3), I expect I'll
run out of keys, in which case I may be asking for a multiplier key :-)

I'd prefer not to use the CONFIG menu except for config and to avoid it as
much as possible in everyday use. I personal think the config menu should be
kept for that - configuration as opposed to operation.

Re: [Elecraft] K3 - qsk keying loop

[Don Wilhelm]

Barry,

For amplifier keying, the K3 has an adjustable T-R delay that is very 
much longer than that provided by the K2.  It may be easier to use that 
than fooling around with the external TX inhibit function.
The TX inhibit is more useful to folks who operate VHF/UHF with a 
sequencer to switch a chain of preamps and antenna mounted gear between 
TX and RX - it can also used to steer the keyer input to one of 2 
transceivers in SO2R setups.

I believe there's an omission in the manual - TX INH is not listed in
the CONFIG menu section and I believe it should be.

I'll ask Wayne about moving SPKR+PH to main menu.  But accessing CONFIG is just 
as 
easy as accessing MAIN.  Its just a hold instead of a TAP.  Remember though we 
don't want many items in MAIN.

You can also program that item to one of the 10 programable buttons.

An UNDO function is something on the list already, but not a very high priority 
right now.

Re: [Elecraft] K3 - qsk keying loop

Barry,

Something was added to provide a "TX inhibit until PTT" function.  That 
discussion was late in the Field Test cycle.  I was involved on the 
sidelines of the discussion even though I was not a field tester.


The bottom line is that it is "in there", but I have not combed the 
latest documents to determine where it is.  Look through all the menu 
items related to keying.

Hmm, for 30 bux you might be better off ordering the 8 pole as an
extra and keeping the 5-pole for use in a home-brew project or to sell
to some home-brewer. It's got to be worth more than the credit you're

set "bias" ON for Front and OFF for rear (or visa versa) and as I switch
from front to rear mic, the bias stays where I set it for the mic selected.

This does not seem to be true for the "H" and "L" parameter.  Set Front to
"H" and rear is automatically set to "H" - set rear to "L" and front is
automatically set to "L" - this parameter (Boost) does not currently seem to
be independent.

1.  Can this parameter setting be made to follow the selected mic input?

TX Equalizer:

Currently, when one sets the TX EQ for either the Front or Rear mic input,
that setting automatically applies to the other input.  So if you have very
different microphones you may not only have to switch the "Boost" (that's
what the built-in "help" banner calls "H" and "L") but you also have to
readjust EQ settings.

As an example, my K2 Proset requires very different EQ settings than my
Shure 444.  One is on the front and one is on the back.  It sure would be
nice to not have to readjust the EQ each time I switch mics.  BTW: the 444
works extremely well on the K3!

2.  Can the TX EQ setting be made to follow the selected mic input?

LOW Power Tuning:

Having to use the rotary Power Control to reduce power for the purpose of
initially tuning up an external manual tune amplifier and pressing the
"Tune" button is cumbersome - not to mention remembering to do it!

Some sort of scheme (menu item?) that allows one to select a "Tune" level
(set to the user's choice) would facilitate this.  Maybe something like -
Push and hold Tune for 2 seconds to apply 20 watts (or the users choice),
tap to exit - or - push and hold Tune for 2 seconds to apply 20 watts, then
push and hold again for full power (what ever you actually have the Power
control set to), tap to exit.  I'm sure someone creative can come up with
something better than this but you get the idea.

3.  Can a "low power tune" function be implemented?

Admittedly, these are "convenience" requests that simply would facilitate
what I do how I operate.  I'm guessing that there may be others that would
find these options of value.

What a great rig! Thanks!  73 es gud dxing -- Don N4HH K3 #83

One would think that folks who laid out money, as an insurance for delivery,
as a way to have their units sooner, or heavens forbid, actually feel that they
supported the manufacturer by sending money first, would receive some priority

[Elecraft] K3 2nd run priority via-a-vis deposit

[DOUGLAS ZWIEBEL]

I ordered my first K3 at Dayton 2007 and I was certainly under the
very clear impression that those who placed a deposit would be given
priority over those who did not.  I happened to pay in full.

Yes, it does seem that the rules changed somewhere in mid-stream (an
unannounced change).  I know that I am not the only one who felt this
way because others who ordered at Dayton and did not place a deposit
felt that having to wait until the "end of the run" was fine with
them.

I suppose that this entire concept never made a whole lot of sense to
me because "why should Run #1 guys w/o a deposit receive priority over

[Elecraft] K3 - qsk keying loop

[Barry N1EU]

I'm surprised to notice no provision for tx enable/inhibit signals
(qsk keying loop) on the K3.  I'd appreciate hearing comments on why
this wasn't part of the design and what the timing safeguards are in
the existing "key out" signal to prevent hot switching on make/break.

Re: [Elecraft] Online Orders: both international USPS options were not

[MARK HAMPTON]

Chris,
 When I made my K3 order back in August, I was able to select either US 
P.O. option.   It seems since then that the order form has been changed and 
from others comments, it seems the UPS, even though more expensive, may be the 
better option - for here in England anyway.

Re: [Elecraft] S-Meter calibration (K2)

[Don Wilhelm]

Werner,

There is no 'correct' answer, each operator can make his own choice on that.
I usually set the S-meter on 40 meters with a 50 uV signal and the 
preamp off.  Other bands may vary somewhat, but this seems to give me 
the most consistent behavior.  Note that I usually operate with the 
preamp on for 20 meters and higher bands.  Whether I use the preamp or 
not on 30 meters depends on the state of atmospheric noise at the time.  
If atmospheric noise is evident on any band without the preamp, using 
the preamp will not be a benefit.  Switch the antenna on and off to tell 
how much atmospheric noise is present - if the receiver noise level 
increases when the antenna is connected, then the atmospheric noise is 
higher than the receiver noise floor and more preamp gain will not be of 
benefit for hearing signals.

[Elecraft] Frequency Shift

[David Robertson]

I would like to thank all who responded to my question about frequency shift 
during filter bandwidth changes on my K2 (see below).

It appears that the shift is no larger then 20 HZ so I guess everything is 
normal.

Thanks again and happy holidays to all.

Dave KD1NA

I am the owner of 2 K2s, one a K2-100 and the other a qrp model. I built one of 
the rigs myself but completely aligned both rigs.

My question.
What can I do to prevent slight frequency shifts when changing filter settings?
Both rigs exhibit this problem. The shift is only about 100 hz at the most but 
I don't think this should happen.

Other then the small shifting problem the rigs work perfectly.

I know there has been solutions posted on this forum in the past but I seem to 
not have the ability to search for them.

I am using the spectrograph program and following the procedure that 
accompanied it when downloaded.

Re: [Elecraft] K3 Curious behavior

[Tom Hammond]

Al:



A)  It's too easy to bump the VFO A dial while in the Menu Modes and  change
an off to an on. It took Microsoft 20 years to build a half way  functional
'UNDO' into their O/S and Apps. I'd at least like to have a glimps at  what
changed when I went back to normal op after accessing the 
menus  -  maybe a quick

list of config items with a * indicating recent changes. Even if  it's a
download to printer it would be good to get a list that shows recent or  last
settings on one page - something that could be scanned when things 
don't  look

right.  I know this may be a reach, but you gotta ask.


When in ANY MENU selection, if you press [DISP] you'll get a terse HELP
discussion of the current functions and it's default setting. Won't take you
back to where you were, BUT it WILL at least allow you to easily find the
starting point again.


B) It'd be nice to have the speaker selects on the 'tap once'  menu list
instead of buried down in the CONFIG list. Can a toggle 
between  headphone only
and headphone +spkr be created? I haven't started into the 
macro  creation phase

yet, and I have discovered some buttons which can do a hot change  without
going into menu, so maybe it's just something I missed earlier. For that  I
would apologize.


You could place that function on one of the (2, if I recall) available PFx
(programmable functions) keys.

[Elecraft] 5 pole/8 pole price delta

[Thom LaCosta]

A day or so ago I had the opportunity to talk to Eric at Elecraft and 
asked him about the 5 pole versus 8 pole
filtersduring the course of the conversation he told me that if 
one wanted to substitute the standard 5 pole
filer with an 8 pole, one would receive a 30 dollar credit, and thus 
the 8 pole filter would cost $90.00 (120-30).


The '"exchange" price is only valid for units that haven't left the 
corral at Aptos.


I expect that when the variable filters are actually available, we'll 
see a market for some of the fixed ones.

[Elecraft] speech accessibility.

[Shaun Oliver]

one of the things I look for in a prospective amateur rig is it's speech 
capabilities. I've seen some talk on the FaQ page regarding speech 
accessibility. what I'm curious about is, how far is elecraft preparred 
to go with it, and how cost effective/prohibitive does elecraft think it 
would be to implement near full speech access? alot of the rigs out 
there these days need initial menu setup and there's no way a white 
stick operator can do this unassisted. I'd like to know how far the 
elecraft team have come in allowing for speech access to the k3.

if I can offer up any suggestions, please let me know

Not yet an amateur.
