[Elecraft] Elecraft; First CW QSO

[Martin . Evans]

Snip

Just a quick note to the list that my newly assembled KX1 serial
number 753 is alive. I made my first QSO this evening just after
2300Z to WU3L (Frank) on 40m.

This was not only the first QSO for the KX1 but was also my first
CW QSO ever (not counting fooling around with friends). The KX1
performed admirably; I was intensely nervous!

I love this stuff! 73!

Well done Scott. My first cw qso was only 12 months ago and I too was a
complete bag of nerves with my straight key. Keep on with the  CW. It's
taken me 12 months and over 500 qso's to get relaxed and confident at 15wpm
but all the practise is paying off now. Hope to work you one day.

[Elecraft] Eurasian ECN - Friday 9 2004

[DL2HRF]

Hi gang,

Condx on July 9 2004 were again not good for longer distances, so I could not 
hear Doc, YI9RVT unfortunately.
But skip was amazingly good for EU contacts, usually it is rare
to have a DL - PA QSO on 20m.
Here are the contacts I made with my K1  at 5W ant R7 vertical:
20m   G3PJT K2#2642  , PA0RBO K2#2406 ,  PA0LPE K2#4125
   F6FTB K2#644
40m   PA0NCV K2#1510  ,  PA0RBO  K2#2406

Thanks guys for joining and see you next time in the EURASIAN ECN !

[Elecraft] Re: was airports and planes -- soldeting stations

[Eric Ward]

I used the soldering station from Circuit Specialists, recommended in 
the "Summary of available soldering stations" article by Tom, N0SS.  It 
appears on the page that you get to by clicking the "How to build and 
test your kit" link, which is on the "Builder resources" page, a link 
for which is on the Elecraft website front page--2 levels down makes it 
a little harder to find ; )  The station was $39.95 as reported--came 
with a tip about 1.5 mm dia, which worked fine--they also sell a few mm 
chisel tip, which is good for the antenna jack.  I had previously built 
a Rock Mite with an unregulated Shack iron.  It worked, but was much 
more stressful--pretty easy to melt the PC board.  I figured no big 
deal for a $25 bag of parts.  But a $40 investment to avoid reducing a 
nice $279 bag of parts to junk seemed like cheap insurance.  They also 
throw in a free DMM on $50+ orders.  And they have a BNC-to-dual 
binding post adapter for a few bucks.  No interest in Circuit 
Specialists, except as a 1 time customer.

[Elecraft] Raspy CW

[Wingkeel]

Hi again everyone,

 I was getting ready for my first Elecraft net report-in with my K2 when 
I heard a buddy in Utah calling off-frequency.  I went down and caught him for 
a short to-do.  A few minutes later, he called me on the land line and said 
my CW tone was very raspy.  While he was on the phone, I shut down the power 
supply and went to internal battery.  It didn't make any difference.  The tone 
sounded awful.  

I'm going to tear into it this morning but I wanted to see if anyone might 
have suggestions first.

   Thanks

[Elecraft] K2: VFO clicks/pops in the presence of strong signals

[Linden, Mike (BRC-Hes)]

  I have just completed "Test and Alignment, Stage II" of K2 #4137.
Everything seems to have gone very well -- all Voltages were in range and it
seemed that everything worked as it should. However, I've now run across a
strange problem.

  I find that clicks/pops occur when I tune the VFO in the presence of
strong signals. For instance, if I set the XG1 for 50uV and tune the VFO up
and down from the XG1's frequency of 7040kHz, I hear clicks/pops (about
S-5/6) when the VFO transitions the following boundaries:

7015.79/80 (click/pop getting very weak here)
7020.79/80
7025.79/80
7030.79/80
7035.79/80
7040.79/80 (XG1's signal is theoretically centered at 7040.00)
7045.79/80
7050.79/80
7055.79/80 (clock/pop getting very weak here)

  The clicks/pops occur when I roll the VFO's last two digits
back-and-fourth across the .79/.80 boundary. The clicks/pops do not occur
when I turn off the XG1.

  I have also noticed that I can hear these clicks/pops when I get up around
7300 and strong broadcast stations are present.

  While I've seen a few mentions of this (or similar problems) in the
archives, I've never really seen any explanation or cure. Any ideas?

  Thanks, Michael N9BDF

Such clicks about every 5 kHz is normal and is part of the construction
of the PLL/VFO-system of the K2. Let me see if I can explain it. The
reference oscillator of the PLL is based on a 12 and something MHz
crystal, with a variable division ratio following it. However, these
steps would be way too course, and therefore the crystal is pulled by
varicaps over about 5 kHz between every change of division ratio. The
pops you hear is when you are the end of the pulling range, and the
divisor changes and the varicap voltage goes to the other end of the
pulling range.

[Elecraft] K2: receiving noise without antenna on certain qrgs

[Rolf . Schroeder]

Dr OMs,
currently, I am experiencing noise on certain frequencies while
receiveing while no antenna is connected. To receive this noise, one has
to touch the key connector. This noise can be heard on e.g. 7010 khz. We
have experienced this noise with several K2 in our local ham club. Could
this be a bad ground connection of the key connector?

Re: [Elecraft] K2: VFO clicks/pops in the presence of strong signals

[Don Wilhelm]

Mike,

You are hearing the PLL reference transitions (Sverre explained it nicely),
but they should be at a low level and not very noticable unless you listen
closely.

If you happened to run CAL PLL without the bottom cover in place, those
clicks will be louder than normal - so re-run it with the cover on.

You may be able to reduce the intensity of the clicks/pops by moving the PLL
reference voltages a bit - be certain 80/75 meters is entirely within the
specified range.  Of course, re-run CAL PLL after shifting the PLL range.

73,
Don W3FPR

Re: [Elecraft] K2: receiving noise without antenna on certain qrgs

[Donald Nesbitt]

Hello Rolf.  Yes, I have noticed the same thing (it appeared that I was
picking up noise generated by my nearby computer and that the noise was not
being internally generated in the K2) when touching the nut on key socket on
the rear of the  K2.  This nut should be "ground" but I discovered that it
was not - and - that the "sleeve" on the internal connector (key jack)
rotates within the housing (could be broken or something?).  I scraped off
some of the paint under the external nut in order to make sure that at least
the nut was making a good ground connection to the chassis.  That seems to
have "cured" the noise pick up.

Now I am hoping that it also "cured" a problem that I have noticed when I am
in the field using the internal battery - that being  that after a while,
the keyer will just start operating by itself sending a nice string of dits!
Only happens when the keyer paddle is plugged in - and - yes - I have
checked the connections on the paddle for possible shorts as well as
substituting another paddle with the same results.  As long as the cable was
not plugged in to the jack, the "self generation" did not occur.  I have not
had a chance to check out if grounding the nut has had any effect on this
"feature" yet - hi  73 es gl --don n4hh K2/100 #2028 etc, etc!

[Elecraft] General Coverage

[Bob Miller]

Hello,

I'm the builder of #4175 and have a question concerning the lower end of the 
spectrum.  I was attempting to listen for the VFO of the 2N22-40+ that I'm 
building at 2085-2185mhz.  I don't hear the VFO nor do I hear anything else 
down there.  I tuned into the AM broadcast band and couldn't hear a single 
station.  Is this normal for the K2 or do I have a problem?

Thanks,

Bob

[Elecraft] re: LoTW

[SHEAJOHNW]

I enjoy receiving paper QSLs because they are more personal, exotic, and 
interesting.  None-the-less, I must acknowlege the utility and potential of 
electronic QSLing.

I upload all my new log entries and have 1485 QSOs logged to both eqsl.cc and 
LoTW.  On LoTW, I have made 302 matches (20 %).  Most of the matches are PSK 
and RTTY contest QSOs with many repeats.  I have only 25 DXCC entities credited 
through LoTW. 

On eqsl, I have made 404 matches with 39 countries and 36 US states credited. 

LoTW appears to be most popular with NA operators, especially contest and DX 
expedition operators.  eQSL appears to be more popular with non-NA operators, 
although many non-NA operators appear to dislike any electronic QSLing.

One would think that LoTW would be ideal for high volume DX and rare DX 
operators because the high expense of paper QSLing and that the losses through 
mail theft could be avoided.  

It is much easier to periodically upload 200+ contest QSOs to LoTW and eQSL 
than to print and mail 200+ cards.  The results are also available almost 
immediately and can be printed if necessary for verification.

Negative are that while one can keep paper cards indefinately, the longevity of 
the LoTW and eQSL systems are unknown, and any future acceptance for credit 
should they stop operating.  One can also look at old cards from exotic 
locations years later.  Looking at a computer listing of the QSOs is a lot less 
satisfying.  Of course, paper cards can also become lost.  There needs to be a 
printable verification system to backup the credits now within the ARRL and 
eqsl computers.

It is unfortunate that eQSL.cc and LoTW cannot coordinate and make their logs 
available for virtually all award credit.  Currently, eqsl is not accepted for 
any ARRL awards and LoTW is accepted by ARRL only for DXCC credit.

RE: [Elecraft] K2: VFO clicks/pops in the presence of strong sign als

Sverre,

  Now that I think about it, it appears that the magnitude (strength) of the
clicks/pops is proportional to the strength of any nearby signal. Does that
make sense based upon you knowledge of the PLL/VFO system?

Re: [Elecraft] K2: receiving noise without antenna on certain qrgs

[Tom Hammond]

Hi Rolf:

I have noticed a similar thing for the past several years.

I think what I'm receiving as 'noise' really might be either AM or FM 
broadcast though... as it seems to have some small amount of modulation to it.


So far I have not been able to determine the cause OR the solution to the 
problem... but it definitely IS there.

Re: [Elecraft] K2: receiving noise without antenna on certain qrgs

[Daniel Reynolds]

I have experienced intermod of local AM broadcasters as high up as 40m. I was
using a 100 ft long wire up about ten feet. It was setup one way (E-W), and it
wasn't noticeable, but when I turned it the other way (N-S), I believe that it
may have interacted more with the power lines several hundred feet away
(parallel with the lines). This is in an urban/suburban setting.

As a side note, I believe that the local power lines are carrying quite a bit
of the local AM signals based on experiences I've had listening to AM on the
car radio and being stopped at a light immediately under power lines. I'd be
tuned into one station, and another station(s) would bleed right over it.

So - your theory might be correct based on my experiences.

Several months ago I bought and installed an ICE high pass filter (402X) 
for the AM broadcast band (it cuts off at about 1.7 MHz). I noticed a drop of 
a few dB in the overall BG noise level on 160. I didn't compare it on other 
bands. Just to make sure it wasn't loss in the filter, I ran a response on the 
filter with a calibrated generator and scope. It wasn't.

[Elecraft] KX1 Minilog Comments

[Dennis Payton]

It works better for me to flip my KX1 up to access the mini-log instead of
flipping it sideways, because flipping it up gets the paddle away from my
writing hand, where I might accidentally engage it. So, when I cut out the
sheets, instead of following the pattern, I cut the corners out of the top,
and put the slots in the bottom. You actually can't tell they're not
supposed to be that way.



Also, I prefer a scratch sheet when I'm operating, so I found some 4"x 6"
Post-It notes, and cut the tops to 3-3/4"x 1". Then I stick them on the log.
It works pretty well, only needing to be moved once while filling out each
log sheet. The action of removing them from the pad makes them want to curl,
so I bend them the other way before cutting them down, and do several at a
time.



When I put more than two log sheets (business card material) on the rig, the
knurled screws stick below the feet, so I'm considering either finding some
screws with shorter heads, or buying a couple extras and grinding their
heads down. Actually though, two sheets has been plenty for me.

Re: [Elecraft] General Coverage

[Don Wilhelm]

Bob,

It is not abnormal - the amount of out-of-hamband range may be slightly
different from one K2 to another.

You may be running out of VFO tuning even though the numbers change.  If you
want to verify, check the voltage at the left end of R30 on the RF board.
If it is less than 0.5 volts or much over 7.5 you have run out of range and
it will tune no further.

73,
Don W3FPR

RE: [Elecraft] General Coverage

[Ron D'Eau Claire]

That's normal because of the way the dial works. 

In normal operation the dial readout is not directly related to the VFO
frequency. It's what the logic *assumes* would be the frequency, assuming
the local oscillator can tune to it. There's no direct measurement of the
local oscillator. The local oscillator frequency is only measured in CAL
PLL. 

When you run the CAL PLL, you look up the internal counter to the L.O.
output and the K2 logic  measures the frequency of the L.O. at various
tuning voltage levels. It then creates a "table" of values that says "If a
tuning voltage of 'x' volts is applied to the L.O. tuning, then the receiver
ought to be tuned to 'y' kHz."  And it's that 'y' kHz frequency that is
shown on your dial in normal operation. 

Think of it as an old analog dial with numbers written on the face so you
can see what frequency it's tuned to by seeing where the pointer is on the
dial. Running CAL PLL tunes the K2 across the tuning range and "writes"
numbers on the dial at intervals so you can see what frequency you are tuned
into when you are operating.

Unlike the old analog dial, there's no "hard stop" at each end of the range
saying that you can't go farther. It'll just let you keep tuning and tuning
and tuning. 

So, if you tune outside the L.O. range, the numbers will continue to change
on the dial, even though the local oscillator can't be tuned to that
frequency.

Re: [Elecraft] Insulated Backstay

[brianb]

Don,

I did this for a time on my 34' boat. It worked with the SGC tuner (not 
too suprising) and I made contacts. It had the added advantage of 
lighting all the LED's on the boats power panel, a great indication of 
radiated power, and woke up the off watch crew that were sleeping with 
their hand against the chain plates where the standing rigging feeds 
through the deck. Oh, and the other cool phenomena was the way the 
autopilot would go offline on voice peaks leaving the boat to round up 
with the spinnaker wrapping and flayling away against the head stay.


Brian n6iz/mm  s/v redsky 



Don Melcher wrote:


Mike

The 23' feet dimension is specified because that is the shortest length
the tuners like the SGC230 and Icom AT120/130/140 AH2/3, etc., will load
on 2 MHz and 2.182 MHz is the "distress" frequency on Marine MF - though
not monitored much outside the US any more.

I have done computer modeling of a typical cruising boat - a Valiant 40
- and found that actually the BEST antenna was to only insulate the
bottom of the backstay and load the whole rig, AS DISCUSSED in the
current editions of the ARRL Antenna Book. But I got tired of arguing
with people that this would actually work - "But it is a short!" - as I
was advocating it long before the Antenna Book, and gave up. And - in
some cases it didn't work very well - on a ketch rig or with a "split"
backstay. On a sloop, with a single wire from the mast to the stern - it
is killer. In a lot of cases, we simply ran a 6 gauge wire back from the
base of the mast or the forestay to the ground of the tuner and jumpered
all the fitting toggles with wire for good continuity - forming a big
"loop". The one insulator was because without it, there would be a lot
of leakage from the chainplate at the feed point to ground after the
stern gets coated with salt spray (but some installations worked OK
without it anyway - Brian may recall Bill Parks' Islander 36 Stray Cat
Blues about 2 or 3 races ago and his effort before that - Bill
introduced the idea to me when he was interviewing me for an article in
Latitude 38. It was in a book that was published some years ago on Ham
Radio and Cruising and the author discussed not using insulators - at
first I too said it wouldn't work - then I thought about it for a
while).

For an insulated stay. a length of 45' seems to be (a stretch of the
word) "optimal" in that it is efficient on the lower frequencies yet not
too long so it maintains a decent angle of radiation on the higher
frequencies. In reality - an insulated backstay is a pretty poor antenna
when you look at the pattern as on most bands there are two pretty deep
nulls about 120 degrees off the bow. Fortunately - they are fairly
narrow. But you won't be able to achieve that length on a W32. A 23'
whip as typically used on a power boat and most multi-hulls has an
almost perfect omni pattern and a good launch angle - of course -
assuming the boat is upright in the water - which is often NOT the case
under way.

IN short - no matter what you do - it is a compromise and you would have
to work REALLY hard to screw it up so it wouldn't work as long as you
follow good engineering practices. I have never seen an Icom tuner fail
to load anything on any frequency - not the same can be said for the
SGC230 (but that seems to be a different problem where it just won't
tune sometimes without being reset) or certain SEA tuners (the 1635 will
not load a 1/4 wave on 4.146 MHz - the check-in frequency for the PacCup
race - go figure - and that is EXACTLY what they cut the backstay to on
a Santa Cruz 52 - I received panic calls from three boats just before
they were leaving on past Pacific Cups who had that tuner installed by
someone because it - with the companion SEA235 radio - was light weight
- didn't bother to check if it would work). SEA's other tuners (like the
1631) do not appear to have this problem and like the SGC, will work
with any radio. 


As far as grounding - there are many methods - but the only one I can
say WILL work is bronze plates (drag is NOT an issue on a Westsail 32) -
I recommend 2 of the 3" x 12" - and I have close to 500 installations
now with no RFI problems running 150 watts using e-mail to back that up.

I am not saying other methods WON'T work - just that it is difficult to
predict the results and it can be a tremendous amount of work and
expense with poor results. One thing that has been determined is SOME
sort of direct sea-water contact is needed.

[Elecraft] Re: Log Book of the World - LoTW

[B. Scott Andersen]

Here are my stats, consistent with what others have found:
You have 2,343 QSO records
You have 260 QSL records
That's roughly 10%.
And these represent only 28 countries.

I did the WAS and DXCC thing with regular cards. I have no
idea how long it will take to get 100 DXCC entities to QSL
via electronic means. No time soon, though.

LoTW's interface is, well, boring. No pictures, no comments,
no interaction at all. It is like reading an accountant's
ledger.

eQSL, on the other hand, lets you interact with folks. If
you've got time skew, the other fellow can say "wrong time"
or "wrong band"; on LoTW, it just silently fails to match.

I do all three but only get the thrill from the paper cards.
I QSL direct when the other fellow allows it. I pay through
the nose but get a card in good condition and, usually, a
cool stamp on the envelope.

Now that the KX1 is alive, I'm planning to do it all again
with QRP and CW. Again again!

Hope this answers your question. 73!

Roy,

Thanks for your mail. Although I am using a balanced antenna system, on some 
bands particularly 40m there is still a significant amount of RF in my shack.
Your grounding situation will be a lot worse (been there, done that, got the 
Tee 
shirt !)
It only needs a small trace of RF getting into the audio side to make your 
transmission sound "fuzzy". The RFC mod I did got rid of all the RF feedback 
problems I was getting, without affecting the TX audio frequency response one 
jot. Anyway, putting it in can do no harm.
