Re: [Elecraft] K3 Transverter drive problem

[Alexandr Kobranov]

Hi Mike,

your problem is in SSB or also in CW mode or in both?

There are no visible spikes on DB6NT 144MHz transverter/25W out.
Firmware 2.10 now implemented.

73!
Lexa, ok1dst

AD6XY - Mike napsal(a):
Thanks for the Email suggestions. 


Setting tune power back to normal did not fix it. It fixed it for one cycle.
I also had my K3 lockup in the config menu. I suspect some problem with the
new beta firmware to be the cause, possibly corrupted memory or something
like that. I have gone back to the old firmware and the system is working.
The overshoots are still there as you adjust the power control but they are
much smaller.

The K3 low level output from the KXV3 produces high power spikes before
settling to the correct level - which it then holds until you change mode,
or power setting. It also produces spikes at full power ( a few mW) as you
turn the power knob. When I originally tested the transverter interface, I
used an analogue power meter, so I would not see these spikes. I can see
them clearly on my oscilloscope for a few fractions of a second before the
ALC acts.

The effect is of course for the transverter to over drive and then settle
back. Obviously I am doing something wrong here but I am not sure what it
is. The K2 does not do this but it is making transverter operation
impossible with my K3 until I can find out how to fix it.

The curious thing is the way the spikes appear as you adjust power. It is
like the CPU is forgetting the ALC setting, reading the op-amp output,
thinking for a bit and then setting the correct gain. I must have some
setting set incorrectly.

Mike

PS

The K3 also suffers from the same transverter failure mode as the K2 - if
you power off the radio in a transverter band, the transverter stays on in
transmit mode because of the way the PTT works and because the K3 does not
send an "off" command on the auxbus before shutting down. The result is a
very hot transverter power amplifier module the next morning. Perhaps we
could fix this using one of the digital outputs?

Re: [Elecraft] [K3] Software suggestion: a more prominent TEST indicator

[Brett Howard]

HAHA...  At FD one of the operators said... "Man I really love the way
the receiver sounds but NOBODY will come back to me".  On his next
transmission I noticed that there was no RF showing up on the bar graph.
Then I noticed the flashing TX...  I mentioned to him that he was in
test mode.  Poof one button press and miraculously he was getting call
backs! :)

It's just too easy to miss the little blinking TX annunciator if you've left
your K3 in test mode. How about once in a while doing something more
dramatic like scrolling TX TEST across the VFO A display, or flashing the
display, or making the SWR and power meter displays flicker in some
obnoxious way, or ...

The challenge is to think of something that doesn't impair any useful aspect
of test mode.

RE: [Elecraft] [K3] CW feature: Swing?

[Ron D'Eau Claire]

Well, Arni, this is a case where mileages *do* vary. I, for one, find a
reasonable amount of "swing" improves copy and reduces fatigue. But, then,
I've been listening to it from both commercial and amateur operators for
over half a century now...

An awful to of good traffic was handled long before "keyers" came on the
scene. 

I recognize that a lot of today's Hams, experienced only with
machine-perfect code with a pure sine wave sidetone, have trouble copying
anything else. I was much the same back about the time I took my code test.
One doesn't progress beyond that point without the same effort it took to
learn CW in the first place: practice. With keyers and keyboards so common
today, that's not as easy to find as we did. That's why I strive to hold the
best spacing I can on my bug when working someone using a keyer, but I have
no illusions that I'll ever match the machine perfect timing of a keyer. 

The "music" argument makes sense to me but I'm no musician, just a
commercial and amateur CW operator with a *lot* of CW traffic behind me sent
by ops on bugs that were a joy to copy, and some who weren't. (Some things
never change ;-)

That is correct.  A Dash has three times the length of three dots, no more,

Depends on if you are talking K3/10 or K3/100 either way you'd probably
do just fine with a 25A.  If you want a little more room you'd be just
fine with a 30A in there too.  Being that is what your connectors are

Re: [Elecraft] Lightness of the K3

[Fern Rivard]

Hey you guys, better put a brick on top of it or a chunk of lead to nail it 
down to your desk. Most people complain that their rig is too heavy and now we 
have the supper light K3 which don't weigh a lot but performs better than any 
other rig on the market. This kind of reminds me that years ago the land mobile 
import radios had a habit of putting some weights inside their hand mic as most 
radio users thought that if the mic was very lite that it then must have been 
poor quality. They were simply trying to make them feel heavy like the Motorola 
hand mics. I just don't get it with always someone bitchin' and nit pickin' 
this awsome performing radio. Please give it a rest and let the folks at 
Elecraft do their stuff.
You all have a good day from Fern with K3 #412

My K3 is fully loaded with all currently available options including the 
100 watt PA. It sits on a shelf just above the laptop computer used for 
logging and other functions. I haven't polished the shelf, but it is 
quite smooth.

Aren't you the lucky one? I ran additional tests the K3's susceptibility 
to sliding by placing it on top of several other rigs and pushing as in 
my earlier "shelf" test. It was unmovable in all of the tests, 
apparently without regard to the cost of the subordinate radio. The 
relative roughness of the painted surfaces gives the feet on the K3 
greater grip than the smooth shelf offers. I'll continue to use the 
plastic shelf liner as it is only 1/32 inch thick and a lot cheaper than 
an FT1K. Other alternatives, such as roughing up the shelf surface with 
sandpaper, don't appeal to me.

You didn't have to stay within the circle. W0SAA was a different FD entry 
than W0SA, and could be separated by any distance since the scores were 
separate.

I'm not sure what your definition of "competent contester" is, but IMHO, if 
you gave out 154 QSOs and had a good time, that's a core competency!

--
IMHO, it should be possible to have multiple power levels on FD. Here's one 
way it could be done:

FD considers each "band/mode" a separate entity. IOW 40 CW is separate from 
40 phone, 20 phone is separate from 40 phone, etc. When you fill out the 
summary sheet, you enter the number of QSOs per band/mode.

Why couldn't each band/mode have its own power level, and all QSOs *of that 
band/mode* would be scored at the highest power level of that band/mode? A club 
could then run a mixture of the three power levels if desired. Only a minor 
change to the summary sheet would be needed. That way, a club might decide to 
run QRO on 75 'phone, low power on 20 digital, QRP on 40 CW, etc., and each 
band/mode would get its own power multiplier. That would maximize interest and 
avoid the need for things like the W0SA/W0SAA split described above.

IIRC, one of the purposes of FD is exposure to new and different things. So 
the QRO folks could see QRP in action, and the reverse. 

It used to be done that way. Before 1971, the same FD group could have 
multiple power levels by band/mode. (I wuz there!)

The change was made for FD 1971 "to simplify scoring". But that was long ago, 
back in the days before computer logging and online log submittals, when 
everything was done by hand. That's ancient history now; why not a better 
system 
that rewards diversity?

The way to get it is for lots of us to write the Contest Advisory Committee. 
I would not be surprised if none of them knew that, at one time, multiple 
power levels were allowed in the same FD group.

Just IMHO

1. Transceivers with low phase noise and broadband transmit noise.
2. Narrow-band filters between transceivers and antennas.
3. Antennas placed as far apart as possible.
4. Antennas oriented for minimum coupling.

Murphys' Maurauders used to (still does?) run that kind of operation. 
One "secret weapon" they had was a set of helical resonators for the HF
bands.   As I recall, the 20 meter version was about a foot in
diameter.  They were narrow-band enough to allow simultaneous CW and
phone operation on the same band while maintaining reasonably low
insertion loss.

The problem is that, even if one transceiver is "perfect" (for example,
a K3 :=), if the other transceiver has excessive phase noise, then BOTH
stations will experience interference.  The only cure is to use a
narrow-band filter on the "dirty" transceiver.

For FD stations located near the east or west coast, one effective
technique is to locate all CW antennas on the north end of the site and
all phone on the south end (or vice versa).  Since the main interference
problem is between phone and CW stations on the same band, that gets the
antennas as far apart as possible and orients them so the interference
is off the side of the antenna, where most antennas have minimum pickup.

Re: [Elecraft] Lightness of the K3

[Don Wilhelm]

Lee,

You must really have a strong button pushing finger - mine takes an 
estimated 10 pounds of force to move it.  The rear feet and the bail 
pads grip tightly to my desktop.  It takes less force if the front bail 
is retracted.


You might try cleaning the rear feet and your desktop surface (dust will 
keep the feet from sticking).  If you are operating with the bail 
retracted, you could put some small (thin) rubber stick-on pads under 
the plastic front feet.

I am thinking of putting a "stop" behind the rig of some sort.  Anyone dealt

Re: [Elecraft] Lightness of the K3

[K9ZTV]

For the life of me I can't figure out why you guys are having this 
problem unless you are using stripped-down versions of the K3 sans 
amplifier, ATU, etc. which would mean a lighter rig, I suppose.  Or else 
the surface your K3s are sitting on have been waxed or polished.


I can push and hold any button on the front panel, including those on 
the left side, and the rig simply doesn't move.  It's sitting smack dab 
on top of an FT-1000D with all four K3 feet in contact with the painted 
top, no bail being used, and it is completely rock-squat-dead-immovable 
with ANY button activation.


But again, check out my earlier post today about a substance called 
HOLD-IT (or derivations therefrom).  It would definitely solve your 
problem with no adverse side-effects.

I use a rectangle of clear, ribbed plastic shelf liner as a mat under

Bruce and Dick,

Thank you for your suggestions. Turns out the problem was a defective
USB/Serial Converter. All if fine now.

I guess all the dirty power, even though I had a UPS in line, got to the
converter some how. Or maybe it just quit.

I am rather large guy...with big hands.  I have mine sitting on the bail on a

Thanks to all of you who replied with great words or wisdom

I'd try a different cable and also try accessing your K3 with the K3 Utility
from a different computer.

The K3 Utility tries all the baud rates in its attempt to communicate with a
K3.  Just click "Test Communications" under the Port tab.

You might want to buy the more expensive form of this material at a 
woodworking store.  It is used for routing and sanding wood 
pieces.  I would think, given the application, that it would not harm 
that surface.  But, as they say, YMMV.

[Elecraft] Get Well Quick Tom!!

[Kevin Rock]

This is probably the least off topic subject which has ever appeared on the 
Elecraft Reflector!

I was unsure how many knew of Tom's impending surgery but now that the subject 
as been broached I wish to add my best wishes to the lengthening list.  

Please get well quick Tom.  We miss you on the Elecraft Net very much.  While 
you are recovering I am sure we can get a set of paddles in your hand and a rig 
in front of you.  I wish to take you up on your promise for more 'OUCH' on my 
road to CW proficiency.  With your help I may be able to become worthy of Net 
Control Operator 5th Class.  

Until we meet again on the air I wish you an easy surgery and a quick and pain 
free recovery.  
   Good luck Tom,
  Your friend, 
 Kevin.

P.S.  All the best to the angel you live with named Jeri!
   K.

RE: [Elecraft] K3 Mic Connection

[Bruce McLaughlin]

If you have a regular Kenwood cable it probably won't work with the PR40 and 
K3.  The PR40 is a balanced mike with a 3 pin XLR connector.  You need a 
special Kenwood cable for the PR 40 to accommodate the 3 pin plug and also to 
allow it to interface with a unbalanced mike input.  Heil does make such a 
cable.  Of course, you may already know that.

Does anyone know of an adapter that some one sells to adapt an 8-pin mic

wasn't connected.  The VOX works so well its not needed.  I'd not want
to use the button on the mic anyway.  I'll just wire up a foot pedal.
Perhaps if I end up having to make a connector I'll just buy some extra
connectors and see if anyone else is interested in buying the extras off

Any thoughts?

Re: [Elecraft] Lightness of the K3

[Mike Harris]

G'day,

Astonished by all this.  I've never moved my K3 merely by pressing the 
front panel buttons.  Anyone hitting them that hard won't be doing them 
any favours.

Regards,

Re: [Elecraft] Lightness of the K3

[Deni]

Yes,  but beware, there seems to be various flavours of this rubber mesh 
material.


I used a black material which has now permanently left it's mesh 
fingerprint on top of a rather expensive rig.


Impossible to remove the fingerprint!

I'm now very wary of using this stuff and wouldn't dream of letting it 
near my K3, well maybe underneath is OK.


But do not... put certain brands of this rubbery mesh on top of a 
surface you really care about,  without testing it out!


I have no idea of the chemical composition of this stuff, but you have 
been warned...

Re: [Elecraft] K3 Huge Hit on CW During Field Day

[Ed K1EP]

I don't have the numbers, but I think my K3 did about 1200 CW Qs at 
our FD site, NS1RA.  We operated 4A.  For a very short time, I got a 
chance to operate another radio, which was of the variety of the one 
I sold after I got my K3.  Sure was glad I got the K3!  And like 
Mack, I would like to know where I can collect my commissions.  (I 
left the LP-PAN at home, didn't feel like lugging another computer to 
the site and the one they had couldn't handle it.)

Re: [Elecraft] K3 "operating scripts" vs. "operating tips"

[W7TEA]

I have gotten used to the rather small K3 front panel or tell myself that I
will someday.
It was this "feature" which kept me from ordering one for several
months. But after putting my hands on one, I figured I wasn't too old to
adapt.

My other rig is a TT Omni VII which I find to be the perfect size with
adequate space
between the controls. Now the hardware NB and second receiver are missing
from this 
rig (I am assuming my KRX3 arrives soon) and the DSP filtering is not as
tight, but
otherwise it is a joy to operate.

[Elecraft] K3 Transverter drive problem

[AD6XY - Mike]

I have come across a problem with my K3 driving an XV50 converted to 70MHz. 

The K3 low level output from the KXV3 produces high power spikes before
settling to the correct level - which it then holds until you change mode,
or power setting. It also produces spikes at full power ( a few mW) as you
turn the power knob. When I originally tested the transverter interface, I
used an analogue power meter, so I would not see these spikes. I can see
them clearly on my oscilloscope for a few fractions of a second before the
ALC acts.

The effect is of course for the transverter to over drive and then settle
back. Obviously I am doing something wrong here but I am not sure what it
is. The K2 does not do this but it is making transverter operation
impossible with my K3 until I can find out how to fix it.

The curious thing is the way the spikes appear as you adjust power. It is
like the CPU is forgetting the ALC setting, reading the op-amp output,
thinking for a bit and then setting the correct gain. I must have some
setting set incorrectly.

Mike

PS

The K3 also suffers from the same transverter failure mode as the K2 - if
you power off the radio in a transverter band, the transverter stays on in
transmit mode because of the way the PTT works and because the K3 does not
send an "off" command on the auxbus before shutting down. The result is a
very hot transverter power amplifier module the next morning. Perhaps we
could fix this using one of the digital outputs?

The third station, running SSB, was a Pro III. We did hear a little of the
"CQ Field Day" voice rhythym in our noise floor at one point, but it was
far, far better than previous years when we totally obliterated each other
if we tried to run on the same band with our low-end ICOMs and Yaesus. We
didn't hear the digital station at all. Everyone who knew enough to be
impressed was _very_ impressed. We may have sold a few K3's this weekend.

Ahem. That was me who did that. I put it in TEST so as not to accidentally
key it up while we were moving the keys around. I should have just turned it

I've been reading on the FD comments and would like to make a couple 
of points and post some opinion.


FD is not a contestit is an operating event.  True!  ARRL has 
said this for years.  I don't think the League even likes to rank 
station that participate as to who made how many points.  If FD 
allowed multipliers (rather than mode points) then we would have a 
contest.  (I would like to see it run like NAQP...now that would be 
a fun contest!)


**
ARRL lists FD in the contest section and publish the scores in QST. 
As Worf the mighty Klingon warrior says, if winning does not matter 
why keep score?


Oddly, even though the event does not have multipliers, many of our 
contacts were very grateful our giving them the somewhat hard to work 
state of Maine.


With the GOTA, public information, extra points for training class, 
visiting politicians and so on, it is primarily an educational 
activity. I do note that you mention that below.


**



FD rules are so loose you can change your class at anytime.



Only in the sense of increasing the number of rigs. If you ever had 
three (non GOTA non extra VHF) rigs transmitting simultaneously, you 
cannot later shut one down and go from a class 3 to a class 2 event. 
(Well, I suppose you could if you do not report the QSOs you make 
with the rig that got shut down.)




FD is to test equipment is rather harsh conditions.  I am sorry to 
hear that at least one K3 died.  It would be interesting to know why.


***
Certainly
***



FD is to show off your new rig (read here K3).

FD is about (for the most part) modest antennas and weak 
signals.  (Unless you are me and decided that air conditioning and 
the lack of bugs were more important this year)  It would be 
interesting to see how many vertical and dipole antennas were used 
this year.  I know some clubs put up beams and towers, but in a 
"real" world situation, I found that a dipole hung on the local 
school's flag pole is about all you can do in the dark and it works fine.



Wire antennas are fully adequate



FD is about how to put several transmitters in a 1000 foot circle 
and making it all work.  I've never been to a 22A, but I bet that is 
interesting on HF.


*
How do they do that?
*



FD is about bad or poor power.

FD is about cooperation with other hams and learning from mistakes 
in  the event of a "real" disaster.


*
Amen! This is the third year in a row that we've run a 2F operation 
from the local Red Cross Chapter House. It is amazing how much more 
cohesive the team is now than it was 2 years ago. As many things go 
wrong as ever, but we deal with them much more efficiently now.

*



FD is about training (both in technical and operating) skills.


***
and enlightening the public, politicians and served agency officials.
***


FD is about bad or good food depending on who is catering the 
event.  I've had both, and the K3 can't improve that at all.  Hey 
Wayne and Eric, put a good MENU in the K3...would you?  KC Strip 
Steak, baked potatoes, green beans, a nice slice of pie, and a "cold 
one" in the menus.  That would be CONFIG>KC S>BP>GrnB>IR2>807


*
Our club President is an outstanding BBQ chef.
*



FD operation tests the "metal" of both rigs and operators.

Final Thought:  The hardest part of FD is unloading the vehicle when 
you get home and putting all the equipment away when your bone 
weary, bug bitten, sun burnt to a crisp, heartily hungry, and ticked 
off at all the operators who failed to learn anything.  Then you 
realize you got to go to work tomorrow!

I noticed much the same except that all our ops learned something.

RE: [Elecraft] K3 "operating scripts" vs. "operating tips"

[Ron D'Eau Claire]

Ian wrote:

To be fair to Elecraft, that is how 21st-century radios behave.

The rigs we grew up with had "stay-put" controls because there was no 
other choice. Going back to the same frequency, mode, antennas and PA 
tuning that we had previously been using on a given band was a complex 
ritual involving several different controls - some of which could cause 
damage if incorrectly adjusted.

The K3 obviously *could* be programmed to emulate that behavior, so if 
anyone really wants to go back there, by all means petition Wayne to 
include it as a CONFIG option. We could call it "Century= mid20th".

But *please* leave the K3's default setting as "21st"!

-

In spite of your thinly-veiled sarcasm, Ian, I agree with you completely.

I hope Elecraft succeeds in providing the features most people will want.
That will produce the most sales and most success for them. 

But what's popular doesn't mean it's what everyone should or needs to do.
Not everyone wants to play the same game. Not everyone wants to follow the
same crowd. 

There can be a real sophistication and elegance to a simple user interface,
particularly for those of us whose primary interest isn't busting DX pileups
or racking up the largest contest scores.

My observation was that if we have a truly sophisticated radio capable of
complex behavior, it'd be nice if that behavior included the ability to
provide a simple, elegant and intuitive user interface for non-competitive
operating as well.

Elecraft has shown great success as a company by not copying everyone else.
I hope they continue that tradition of innovation.

[Elecraft] K3: 400 hz & 50 hz

[Joseph M. Durnal]

Other radios get quite a ring when using narrow filters.  Why is this
not as bad on the K3?   With the 400 hz roofing filter and the DSP
filter turned down to 50 hz, there is hardly any ring compared to
other rigs I've used.  Just curious.

Re: [Elecraft] Lightness of the K3

[K9ZTV]

I don't have the lightness problem.  But . . .

HOLD-IT, a tacky substance sold through office supply stores (probably 
under various names) to stick pictures onto walls, works like a charm on 
the bottom of paddles.  I have had the same hunk of that stuff since 
college (1960s).  Lasts forever and can be re-kneaded when it gets dusty 
and dirty.  Allows paddles (and K3s) to stay put regardless of how much 
force you apply, but still permits re-positioning.  Leaves no residue on 
the substrate.  Great stuff.

[Elecraft] K2 Field Day

[David N.]

Well this was my first contest with the K2 at field day with the 100 watt 
module. I was really surpised at how cool it ran.
we ran 990 q's on CW only and the heatsink never even got warm. And that was 
with us calling the whole time. Got lots of complements on Reciever 
performance. And of course my response was it is a K2 what do you expect.

[Elecraft] FD: QRO + QRP with pwr multiplier

[Peter Wollan]

For this year and last year, I've added a QRP station to our club's  
QRO FD setup, but I submit it as a separate entry.  As far as I can  
tell, this is within both the rules and spirit of Field Day -- it  
provides another station, another example of radio use for anyone to  
check out, try, or just talk about, while I share in the social  
aspect of the club event instead of being off on my own.  And it lets  
me keep the 5x power multiplier, though without being able to add it  
in as a contribution to the club score.


I ran 1A-Battery (solar), using the call W0SAA, while the rest were  
5A using W0SA (having those two calls available was a coincidence,  
but cute).  The QRP station was my K2, with two wire antennas, a bit  
away from the main stations, which this year consisted of four  
kilowatt stations, plus a 100-watt digital station and a VHF  
station.  I was off to the side a bit, but still within the 1000-foot  
circle of the main group.  Our club is dominated by high-power  
people, but the QRP station got some interest.  Several people came  
by to talk about kits and backpack radios, and one person tried CW  
contesting for the first time -- less threatening without an amp, maybe?


Interference was an issue, but mostly ignorable.  But then, the QRO  
stations had problems with each other, too.  One of the four was a  
K3, and it, too, had some problems, particularly with one specific  
transmitter.  I haven't heard a good account of that yet.  Someone  
here mentioned using a K1 near other stations -- I tried that a few  
years ago, and found that I couldn't hear anything when any other  
transmitter was operating, even a band away.  I haven't tried my K1  
again in this kind of shared space, but I'm surprised anything less  
robust than a K2 could handle it.


I'm not a competent contester yet -- I got 154 contacts, all CW S&P  
-- but I had a darn good time.

[Elecraft] First K3 and Field Day Comments

[Karl Anderson]

This was my first year ever participating in Field Day as a club member and 
operating a K3. What a great event and what a great radio. 

The K3 performed flawlessly, I especially liked the DSP shift and width 
capability, and the NR ability to reduce noise to hear weaker signals. Loved 
the versatility of the K3 and its ability to adapt to the preferences of all 
our club operators. At all times our K3 had three paddles including a bug, a 
WinKey and at least two sets of headphones  connected. During the daytime the 
external speaker and a portable speaker were going for the public. Great to see 
the shift change and a new set of operators get right into the action without 
having to change any of the setup.

My two cents on Field Day:

Even though the intent may be to help prepare for emergency operations and 
showcase amateur radio to the public you have to provide something for everone 
in order to get the most participation by club members.

Our club provided breakfast, lunch, dinner and plenty of snacks and water and 
all the coffee one could ever drink for all it's members. A tent between our 
two operating locations was set up with food and plenty of tables and chairs 
for folks to socialize and enjoy each other. We has two SSB stations, a CW 
station, a digital station, a VHF/UHF station, a GOTA station and a MARS 
station going. County and State officials were invited, a few actually showed 
up. One member lead visitors on tours throughout the day and provided 
educational events. Other members took care of logistics during the day, such 
as getting rid of accumulating trash and keeping an eye on the general well 
being of people in 96+ degree weather. Our public information booth was setup 
to greet visitors and  ready to sign-up and welcome new members into the club 
as well. We had unlicensed folks behind microphones for hours, had an 
unlicensed teenager stay up all night logging for our CW ops. 

Our CW operations were close to 800 feet away from our other setups to help 
with antenna separation but only 50 feet or so from where the public parked 
their vehicles. Had lots of time between my CW shifts to visit and get to know 
other members and watch them participating in their favorite modes.

Don't forget the few who volunteer as your club Field Day Committee to make the 
event happen. They give many hours of their precious time behind the scenes to 
plan, set-up, take-down, clean-up after the event when others are long gone, 
all for the benefit of the members, guests and public.

Sorry to say this was my first Field Day and not my 34th. Doubt I would have 
been there if not for the club and those members interested in contesting. 
Doubt I'll be there next year unless there is an interest in helping the club 
and members who are interested in contesting.

The difference between +/- 30 KHz and +/-26 or 27 KHz is probably 
not enough to notice.  The FM filter should still have a shape 
factor no worse that 2 ... a realistic 8-pole filter should be 
in the 1.6 to 1.8 range at that bandwidth.

Unbalance would effect all modes - even with a narrow filter.  I 
have not checked but would expected the circuit to use a balanced 
mixer specifically to maintain a wider spurious free passband.

Everybody wants something - You guys remind me of a comparison I saw of what

portion of it:

higher ground clearance
tighter turning radius
more maneuverable
lighter weight
less expensive tires
larger windshield
greater visibility
more air circulation
convertible top
sun roof
and many, many more

The model "T" had all of this, but NO, you all elected to give it up for the

In my view, the so called "bug swing" is anything but "nice"!  Why
anyone would try to send anything but correctly formed code characters
is beyond me!

Dave W7AQK



Imagine a world where nobody spoke into the mic.  Instead, rigs had
computer voice generation inside.  What came out were your words, but
spoken by a robotic artificial voice with perfect pronunciation at just
the right speed with just the right tone to cut through and improve
communications.

Keyers have served to make CW nice & uniform but have also taken much of
the life out of the mode for me.  I much prefer to work someone who is
using a straight key or bug and is sending good code that still has a
bit of human flavor to it.

Having said that, I agree with you regarding intentional bug swing.  If
the OP is trying to swing, intentionally messing up the code because it
sounds "cool" then that is a bad thing.

NNMA instead of CQ is a sign of a poor operator who hasn't mastered the
bug.

[Elecraft] K3:Max 'G' & Crash Protection

[Mike McLendon]

I do not recall any specs for the K3 in regards to G force but I can share
the results of an uncontrolled acceleration/deceleration event. FD 2008 for
SCARS (Smith Chart Amateur Radio Society) lime many others is usually an
expedition to a mountaintop cow pasture in VA and always with the best HF
transceivers possible. SCARS operated class 2A this year with K3s. The high
elevation has RF advantages but some minor weather disadvantages as ~40 head
of cattle were killed simultaneously by a lightning strike a little over 30
years ago. There is no protection from strong storms and we often retreat to
vehicles to wait out electrical storms and avoid death etc.

This year, the operating tent had a K3 and other equipment but no people
inside and prior to the start of the event, when the straight line winds of
a thunderstorm uprooted the tent stakes and rolled the tent and its contents
over.  Of course the K3 went flying, smashing into other equipment and
coming to rest upside down underneath the table. All this after being
carefully transported 180 miles in a padded computer bag.

An external inspection revealed scuff marks and a deep dent 6-7 mm deep on
the right side panel between the voltage regulator (VR) mounting screws.
Shaking the radio revealed no rattling and the top cover was removed for a
further look. The look inside revealed that fortunately, the point of
deepest impact penetrated  above the RF board and missed the VRs! A
subsequent smoke test passed as did RX & TX field checks.

The banged up rig performed continuous duty with excellent FD performance in
CW & SSB modes as did the undamaged unit. There were no further un-managed
weather problems as we moved operations to a high-wind resistant tent. There
were mostly first time K3 operators on duty, experience levels varied but
all ops reported that they really - really liked the rig. The learning curve
for basic FD operation was very short.

I guess I'll order a new panel from customer service today and maybe a
couple of VR parts in case they suffered micro-fractures or there is
mischief down the road. In any event, I have to hose the K3 down a bit and
get the rib grease off the front panel. Very impressive integrity - nice job
Elecraft Mechanical Engineering!

Re: [Elecraft] FD - Some Comments about the Event

[Dan Romanchik KB6NU]

Well, my daddy always told me, "Son, if it walks like a duck and  
quacks like a duck, it's probably a duck." That being the case, if  
it's not a contest, then why award points. FD is a slightly different  
kind of duck than most contests, but if points are involved, then it's  
a contest.


I pretty much agree with all your other points and would add one of my  
own. Field Day is about camaraderie. Events like this help hams who  
already know one another to get to know one another better and to meet  
new hams (and potential hams) who may come to visit.


73!

I've been reading on the FD comments and would like to make a couple  
of points and post some opinion.


FD is not a contestit is an operating event.  True!  ARRL has  
said this for years.  I don't think the League even likes to rank  
station that participate as to who made how many points.  If FD  
allowed multipliers (rather than mode points) then we would have a  
contest.  (I would like to see it run like NAQP...now that would be  
a fun contest!)


FD rules are so loose you can change your class at anytime.

FD is to test equipment is rather harsh conditions.  I am sorry to  
hear that at least one K3 died.  It would be interesting to know why.


FD is to show off your new rig (read here K3).

FD is about (for the most part) modest antennas and weak signals.   
(Unless you are me and decided that air conditioning and the lack of  
bugs were more important this year)  It would be interesting to see  
how many vertical and dipole antennas were used this year.  I know  
some clubs put up beams and towers, but in a "real" world situation,  
I found that a dipole hung on the local school's flag pole is about  
all you can do in the dark and it works fine.


FD is about how to put several transmitters in a 1000 foot circle  
and making it all work.  I've never been to a 22A, but I bet that is  
interesting on HF.


FD is about bad or poor power.

FD is about cooperation with other hams and learning from mistakes  
in  the event of a "real" disaster.


FD is about training (both in technical and operating) skills.

FD is about bad or good food depending on who is catering the  
event.  I've had both, and the K3 can't improve that at all.  Hey  
Wayne and Eric, put a good MENU in the K3...would you?  KC Strip  
Steak, baked potatoes, green beans, a nice slice of pie, and a "cold  
one" in the menus.  That would be CONFIG>KC S>BP>GrnB>IR2>807


FD operation tests the "metal" of both rigs and operators.

Final Thought:  The hardest part of FD is unloading the vehicle when  
you get home and putting all the equipment away when your bone  
weary, bug bitten, sun burnt to a crisp, heartily hungry, and ticked  
off at all the operators who failed to learn anything.  Then you  
realize you got to go to work tomorrow!

Re: [Elecraft] Big print buttons?

[K3KO]

Hi Tom,

I agree with turning on the lights.

As for the big print.  Please get back to me on that when your in your 60 or
70's.
I really envy those who can actually read the characters on their cell phone
keys too.

[Elecraft] FD Blues?

[Gary Gregory]

Well Lee?...you did it mate, I laughed so darn hard I fell of my chair.
(Sure glad I reached for and grabbed the chair and not my K3...Hm)

Hope ALL folks enjoyed the FD, I took part in a couple 2000 and 2001. I was
in Abaquackee, NM.

Cheers,
Gary

Re: [Elecraft] K3 "operating scripts" vs. "operating tips"

[Simon Brown (HB9DRV)]

At the Friedrichshafen show I was talking to a few fellow members of the 
terminally bewildered radio operators club (Last of the Summer Wine 
candidates). Their input was:


1) Radios should have a simple and *large* interface.
2) Assuming good performance, usability is more important than price (all 
children have left home, wives are radio-friendly, bank balances are 
healthy).
3) None bought the K3 despite my recommendations, instead the IC-7700 was 
purchased due to 1) above. The size of the radio was the deal killer.
4) Despite price all were drooling over the Hilberling PT-8000, I seriously 
expect those who did not yet buy the IC-7700 to buy the Hilberling.


My opinion - radios should be big, mobile phones and tax demands should be 
small.

To be fair to Elecraft, that is how 21st-century radios behave.

The rigs we grew up with had "stay-put" controls because there was no 
other choice. Going back to the same frequency, mode, antennas and PA 
tuning that we had previously been using on a given band was a complex 
ritual involving several different controls - some of which could cause 
damage if incorrectly adjusted.


The K3 obviously *could* be programmed to emulate that behavior, so if 
anyone really wants to go back there, by all means petition Wayne to 
include it as a CONFIG option. We could call it "Century= mid20th".


But *please* leave the K3's default setting as "21st"!

I'd love to see the K3 controls do ONE thing. That is, when I select
MODE:CW, I'd like the radio to be in CW mode and not change if I switch VFOs
or bands. If I select ANT1, the radio should remain on ANT1 no matter which
band I choose, etc.

I realize that the complex interconnected functions that have been evolved
are invaluable to serious DX chasers and contesters. And to learn them, the
scripts and  tips sound like a great idea.

But for myself, I'd rather not have the radio "second-guess" me using some
complex logic that I'm obligated to learn in order to operate it ;-)

I'm with you.  I'm not used to using a radio where all the controls 
change state whenever I change bands - I find that feature mainly 
confusing/annoying.  Perhaps after I've put in more hours flying my K3 
it will become more second-nature.

Re: [K3] [Elecraft] Transmit AM through FM Filter?

I think the main concern is for transmit, where another operator may be

reserved band segments, where interference is handled by the capture 
effect.  FM transmissions also have infinite sidebands, and a normal 
transmitter only filters these with the main LC filter.


filter, even if the K3 were driving a 1500 W PEP amplifier the  
transmitted image would be less than .0005 milliwatts of carrier! 


There is also any unbalanced first local oscillator at 15kHz offset. 
Again, it may be far enough down the skirts not to be too much of a 
problem.  (However the suppression requirements are much higher than for 
an SSB carrier.)
