Re: [Elecraft] CQ Contest

[Richard Davis]

My AF knob was 'funny' earlier in the week.  Scott at Elecraft talked to 
me Friday on the phone and patiently waited for me to stop sobbing. 
Later in the day the knob 'crumbled' just before the contest started.  A 
panic run to the hardware store provided a 'jury rig' solution that I 
will probably use as a permanent knob.   ...or until Elecraft offer 
knobs with brass sleeve inserts to absorb the stress caused by the set 
screws.

Echoing others on this thread, the DSP at 250Hz with the 250Hz 8 pole 
filter was used most of the time.  Sweet!  ...I also did notice many 
signals had monstrous sidebands due to 'key clicks'.

As for the RIT comments...  My special needs placed an entirely 
different cast on the fine tuning issue.  Being in the "golden" years, 
and being confronted with the on-rush of "Mad Cow's" malady (ask Denny 
Crane if you need any elaboration) I am  hopelessly challenged in 
contests by the vast majority of 3-letter stations who operate at 30+ 
wpm, who send everything once-especially serial numbers, who use those 
clever non-numeric codes for numbers to spare their electronic keyers 
the extra heat overload, and by the time I get the call sign written 
down I have forgotten the serial number..   sigh

TO the RESCUE!!!  The CW decoder on the K3 is my sweet savior!  I can 
work the high speed guys whose dot streams sound like amplitude 
modulated dashes.   100% accurate copy.  With CW decode the K3 puts me 
in the contest.

And when you use CWT centering maximizing the decoding accuracy, you get 
spot-on, consistently repeatable tuning.  No RIT needed.  Of course that 
assumes search and pounce is the preferred style of operation.

If you park on a frequency and call CQ you surrender tuning control to 
the other guy.  You choose the fight the pile ups you hope will come to 
you.  ...me, I am a 'control freak', I will pounce, thank you very much.

I will probably never be highly competitive in CW contests, but the K3 
puts me in the hunt.   ...and that is enough to satisfy me.

now if the K3 could only send CW using electrical sensors inside my 
green eye-shade visor  How about that Wayne?

...this contest was the most fun I have ever had in 55 years of ham 
radio.  Thank you very much Elecraft!!!

73's and 88's to the gang there,

Richard

Hi, Wayne.

Well, I knew about the Dual Passband capability but to tell the truth, I didn't 
really know how narrow the "focus"filter was ... I can't find any spec on in 
the manual.  It's nice to know that it is nominally 150 Hz, though.

The more relevant issue for me, though, is that I only have one CW roofing 
filter ... the 8-pole 250Hz.  As soon as I activate Dual Passband filtering 
(which works nicely, by the way) I jump into my next roofing filter, which in 
my case is an 8-pole 1.5 KHz filter.  That's pretty wide for a contest 
environment with lots of loud stations like CQ WPX.  I previously couldn't see 
the need for a wider CW filter, but I guess that would be a good reason to have 
one.

For the time being, I think I prefer the knife edge filtering even if I have to 
use the RIT.  In my opinion, it's a real competitive advantage to be able to 
make use of those cracks in the wall to operate.

73,
Dave   AB7E




Dave,

Sounds like you may be a candidate for the dual-passband CW feature of 
the K3. It gives you a 150-Hz "focus" filter, but allows you to hear 
signals either side of this at about -20 dB (the "context"). The 
context width is adjustable with the WIDTH control. See the manual for 
further details.

You do not need the buffer for any Ameritron amplifier. In particular the

[Elecraft] K3 Ground Loop Issues using Ameritron ARB-704

[Alfred Frugoli]

I've just gotten my K3 built and integrated into the shack about a week
ago.  Operated WPX CW this weekend with GREAT success.  Was very happy.

Tonight in setting up FSK, I was getting a lot of "AGN?" after my cq's.
Listening to my signal on a 2nd receiver, I realized that my signal had a
hum on it - basically sounded terrible. Tested in CW mode as well, and the
hum was also there (haven't dug out the mic yet for the dreaded SSB mode to
know if the hum was there as well, but I would suspect it would have been).
Tried changing a bunch of menu settings to no avail.  Then I disconnected
everything from the back of the K3 except for the antenna, power and FSK
input.  Beautiful clean signal.  The hum reappeared when I connected the amp
keying line.

  I've been using the Ameritron ARB-704 Amp Keying buffer, and even though
the K3 can handle the relay voltage on my AL-80 (the key voltage is not in
the AL-80 manual, but I believe it's 125v), I've kept in in line.  However
this seems to be the item causing the hum.  When I take it out of the line,
and connect the rig directly to the amp, no hum.

My shack is NOT well RF grounded, and things are not bonded together at this
point (that's a needed project - but the ARB-704 doesn't have a ground post
to connect to - I'd have to go directly under one of the case screws to
ground it).

Anybody else experience this?  Am I correct in my deduction that the K3 key
out relay will handle the relay voltage on the AL-80?  If so, I'll just
ditch the ARB-704 for now.

Thanks.

Re: [Elecraft] K3 voltage under load

[Grant Youngman]

Maybe there's too much concern to do all the hand wringing?

It all depends on what's between the PS and the radio.  In my case,  
for example,  my 13.8v supply feeds a West Mountain Radio battery  
charger (200AH of battery), and there's a drop there (.4V).  then to a  
WMR distribution box and on to the radio.  I have 13.5v no load and  
12.5v transmit at 100W.  All of the wiring is #10 as short as  
possible.  The APP's are 45A and are properly terminated.  And the  
radio just keeps on chugging.

I've chosen not to be concerned about it.  I  may try to increase the  
RS-70M output to as close to 15v as I can, but my motivation is  
lacking to open up the box and try to adjust the unreachable output  
adjust since nothing is broken.

There are a number of reasons to worry.  If there is a defective 
connection, it could (and will) heat up and melt (or self destruct), 
causing other problems.  I have seen the plastic on power poles melt 
due to incorrect installation and high  resistance.   Typically, the 
voltage to the PA is not regulated, in the sense that it uses the 
voltage supplied to the radio which it assumes is regulated.  It does 
that because there is no room to supply a 20A regulator in the

correct the description of the roofing filter offered for sale a few days
age.

KFL3A-2.1K - This is an 8-pole filter, not a 5-pole as I listed.

I had a lot of contacts all made using search and pounce. The button getting

perfectly even on weak signals. This is a big help for me as I am zero beat

Re: [Elecraft] CQ Contest

[xdavid]

Actually, I discovered that you CAN adjust the RIT while in transmit.  You just 
can't see the frequency offset on the display while you turn the knob, but it 
does change and the display accurately updates when you finish transmitting.  I 
found I was able to rather easily estimate how far the RIT would move as I 
turned the knob, and I often adjusted the RIT to better pick up the calling 
station even as I was sending him my report, or asking for a repeat on his 
callsign, etc.  When running a pile it is usually better to keep the activity 
going to keep other callers from jumping in, so I would often do that on the 
fly as I was adjusting the RIT.

And of course if you have to go very far afield to pick up someone, you can 
jump back quickly to center while you stand by for the next caller (or call CQ) 
by just pressing the RIT/XIT CLR button.

Re: [Elecraft] CQ Contest

[Julius Fazekas n2wn]

Hi Dave,

You do present an interesting point on receiver disparity. I think this has
always been an issue, not just due to radios, but also antennas and
propagation. It is an interesting question that will most likely be a factor
this coming Fall. The winner will still be who has the best signal or maybe
who's rarest and the majority can hear and work. 

Those who will be hurt the most will be the ones who were able to control
large chunks of spectrum.

At what point does it become rude? Hard to say... Generally a really weak
station under a power house won't be there very long anyway, because it is
unproductive, maybe they will last a bit longer now... If the guy who is
running say EU and you're working Asia just off his run frequency, it may be
a minor problem. 20 and 160 could be very different animals if they are
really open...

Ahhh, the RIT/XIT, my only beef with the K3... still can't adjust them while
in transmit. That was a sweet feature on the K2!

73,
Julius

"The other very impressive thing was the narrow filter.  I used a 250 Hz
8-pole filter with the DSP set to 250 Hz, and it was like a knife edge.  I
could operate within a couple hundred Hz of most S9+20 stations and never
hear them --- unmodified Yaesu rigs being the exception (there are still
some HORRIBLE sounding clicks out there).  Whether those stations heard me
was probably a function of whether they were using a K3 or not ;)  The
downside was that I had to ride the RIT most of the time ... I had a LOT of
people call me pretty far off frequency and the only way I could tell they
were there was by the rhythm of their key clicks unless I swept back and
forth with the RIT.

Which brings up a side observation ... there is so much disparity now
between the performance of various rigs that it seems possible to generate
some misconceptions regarding operating skill and courtesy.  I wonder how
many times other stations thought I was deaf or couldn't copy their CW
merely because they couldn't zero beat my signal within 150 Hz or so?  And I
wonder how many people thought I was a LID for calling CQ too close to them
on what was for me a clear frequency because they didn't have as tight a
filtering as I did?  To minimize the latter, I usually opened up the
bandpass a bit when looking for a clear frequency, but the folks with 500 Hz
filters and no roofing filters would have still had trouble."

We've corrected the knob material problem, and will send you 
replacement knobs on request (no charge). Most of the defective ones 
have already been replaced. Sorry you had to deal with it during the

Hi Willis,

I always enjoy reading the post contest comments. They can be fun, informative 
and downright funny. The knob comment was made because his cracked during the 
contest, irritating, but not the worst that could happen and he pointed that 
out in a later comment. It was done in good humor I think...

Glad you did well, and sorry we didn't work. Unexpected circumstances kept me 
from putting in the effort I had hoped, but had a lot of fun working DX on 10 
for a change. Had hoped to add something new, but no luck, need seven states 
for WAS and six countries for DXCC (worked 112 but can't get the QSLs from any 
of the outstanding ones).

Hats off to the Top Band folks, just got card 102 for DXCC LP and all 26 zones 
worked confirmed... A few K2s and K3s in that lot!

See ya in IARU!

Re: [Elecraft] CQ Contest

[xdavid]

I operated SOSB20 in CQ WPX this past weekend and gave the K3 a pretty good 
workout.  I made 1300+ contacts but that pales in comparison to the zillions of 
times I repetitively hit the F1 key.  My wife and I have been building our own 
home the past few years and we still don't have the air conditioning 
functional, so the ambient temperature in the shack was right at 80 deg F much 
of the day.  I set the K3 to continuously monitor PA temp, and even with the 
relatively large duty cycle I was giving the rig I never saw it go above 47 deg 
C.

The other very impressive thing was the narrow filter.  I used a 250 Hz 8-pole 
filter with the DSP set to 250 Hz, and it was like a knife edge.  I could 
operate within a couple hundred Hz of most S9+20 stations and never hear them 
--- unmodified Yaesu rigs being the exception (there are still some HORRIBLE 
sounding clicks out there).  Whether those stations heard me was probably a 
function of whether they were using a K3 or not ;)  The downside was that I had 
to ride the RIT most of the time ... I had a LOT of people call me pretty far 
off frequency and the only way I could tell they were there was by the rhythm 
of their key clicks unless I swept back and forth with the RIT.

Which brings up a side observation ... there is so much disparity now between 
the performance of various rigs that it seems possible to generate some 
misconceptions regarding operating skill and courtesy.  I wonder how many times 
other stations thought I was deaf or couldn't copy their CW merely because they 
couldn't zero beat my signal within 150 Hz or so?  And I wonder how many people 
thought I was a LID for calling CQ too close to them on what was for me a clear 
frequency because they didn't have as tight a filtering as I did?  To minimize 
the latter, I usually opened up the bandpass a bit when looking for a clear 
frequency, but the folks with 500 Hz filters and no roofing filters would have 
still had trouble.

I did have the AF knob for the main receiver crack on me 20 minutes before the 
contest started, though, and the knob just spun on the shaft.  Luckily one of 
the set screws still had enough grip to do the job after snugging it up a bit 
and it held up through the contest.  I've had my K3 since January and had been 
very careful tightening the screws initially.

73,
Dave   AB7E

Many brand new K3 users, some of the "big guns" in contesting are now

Watch for a K2 or K3 in the WVQP, we'll be signing N8Q mobile from a few of

Re: [Elecraft] CQ Contest

[WILLIS COOKE]

I was one of the participants with a K3, but not the one that complained about 
the knob.  I agree with him, but reserve my few complaints for this forum where 
they will be received in the spirit they were made.  The K3 was a delight to 
use, I had a blast and I hope to score well in the Single Operator, All Band, 
Low Power, Tribander category.  Whether I score well or not, it was great fun.  
I made 605 Qs and about 493,000 points.  I hope I have most of those left after 
they remove the busted Qs (G).  I am one more happy contester.

Re: [Elecraft] CW Type

[wayne burdick]

Hi Greg,

Make sure you're not in TX TEST mode, and that the PWR control is set 
to the desired level.

If CW Type is using the "KY" (CW/data keying) ASCII control command, 
note that sending a '<' character puts the rig into TX TEST, and '>' 
restores normal TX operation. You can test this using K3 Utility's 
Command Tester screen, e.g.:

KY NORM;

The above line should send "TEST" in CW with no power output, then 
"NORM" at the PWR knob setting.

Re: [Elecraft] K3 voltage under load

[Guy Olinger, K2AV]

It only takes about ** a tenth of an ohm ** between K3 and power supply to 
drop 1.7 volts at 18 amps.  Size of wire, bad crimp in a connector, tiny bit 
of corrosion, etc., etc.

AND, the tenth of an ohm may be spread out in different places.

I have three feet of #10 to the K3, and I drop from 14.2 to 13.8 at 100 
watts using an Astron RS 35A I adjusted up just a teeny.

This is likely due to "I squared * R" losses in your DC cable; the voltage
is being reduced by the resistance of the cable.   I had the same problem.

How long is it?  What gauge is it?  Are there any fuses or other items

No, not necessarily.  He stated that the 12.3V was measured inside of 
the radio.  That reflects any IR loss to that point and not 
necessarily poor regulation on the supply.  More data is necessary to 
come to that conclusion.

I own an Astron analog power supply, and there is NO fluctuation of voltage

Re: [Elecraft] K3 voltage under load

[Ed K1EP]

I don't think that this is normal.  It depends upon the voltage drop 
on cable between the radio and power supply, as well as any voltage 
drop inside of the radio.  I actually was measuring this 
yesterday.  My supply reads between 13.7 and 13.8 on the K3 meter 
under receive.  With 100W keydown, it was reading 13.2.  This was a 
quick measurement and I didn't verify that the supply maintained 
constant voltage (it should have as it is a 25A supply).  I have 
about 12" of 10AWG cable from the supply to the radio.  I think that 
this drop is typical or maybe even slightly high.  Your drop of 1.7V 
is way too high.  I would inspect your DC cabling to the radio, 
correct installation of your powerpoles on that cable, and the 
connector pins on the KPA3 and KPAIO3.

Re: [Elecraft] HRD shuts down-Prolific drivers

[OE5CSP-Chris]

Here is Simon´s answer to my problem. Does anybody know where to get
prolific drivers which will work with Ham Radio Deluxe?
73, Chris-OE5CSP

Hi,

If you get a BSOD (Blue Screen Of Death) then it's the driver for the 
Prolific cable which must be updated, only drivers can cause a BSOD and with 
VISTA there are new / special drivers.
