And not just for the K2. It turns out that all transmitter phase noise 
plots published in QST going back for many years include a 7.5 dB error 
in favor of the rigs. The lab has identified this error and corrected 
it, so going forward we'll see more accurate numbers.


Much of the error is traceable to a decades-old HP application note 
that, apparently, had been taken for gospel.

Re: [Elecraft] Unique synthesizer LO ?

2006-08-06 Thread John, KI6WX

Peter;
I have posted on the web a detailed set of measurements of the K2 phase 
noise, both in receive and transmit.  The measurements cover a frequency 
range of 20 Hz to 45 kHz.  These measurements can be viewed at:


http://home.pacbell.net/johngreb/k2phasenoise.pdf

The ARRL composite transmit noise measurements that were published in QST 
are in errror and show less noise than reality.  The transmit phase noise 
measurements in the above document are the correct phase noise measurements, 
but they do not include any amplitude noise that might be on the transmit 
carrier.


The K2 oscillator phase noise is good for a simple low-current synthesizer, 
but there are ways to make it better.  I note some of those in the above 
document.  A re-designed K2 RF board could drop the phase noise by at least 
10 dB, which would improve the 5 kHz two-tone third-order dynamic range 6 
dB.

-John
KI6WX



Maybe not the cleverest question of the year but I cannot resolve this one
myself and I'm eager to understand.

It is said that the synthesized LO of the K2 is of a unique design.
Though, when I compare the LO phase noise specs of the K2 and the AOR7030,
the latter seems to show much better specs.

What makes the K2 synthesizer so special ?
I'd appreciate any comment.

[Elecraft] Elecraft CW Net Report for August 6th & 7th, 2006

2006-08-06 Thread Kevin Rock

Good evening,
   Twenty meters seemed weaker than usual with more QRN too.  Forty meters  
had its fair share of QRN and even weaker signals.  However, we were able  
to gather 23 check ins between the two nets.  At least one of them took  
two relays to get back to NCS.  The net has had over 2600 check ins during  
the course of its existence.  435 separate individuals have checked in  
with a variety of gear.  Some have gone so far as to check in with SEVEN  
different Elecraft rigs.  We try to have fun and I think it is contagious.
   The weather reports came in a bit cooler than last week but there were  
a couple power outages.  Mine took a few days to solve completely and now  
Ken is cleaning up after his storm in Fargo.  Hopefully the damage was  
minimal.  Most of us need rain but the folks in New Mexico may be asking  
for their normal sunshine after the flooding on the Rio Grande.  I have  
not heard from my friends from Albuquerque yet about how they fared.  Pat  
and I lived in a house with an arroyo on its back boundary.  The reports I  
read stated our section of town was hit.  Now to find out how bad.

Hello Phil,

	For home or picnic usage, you will be very happy with either one. 
Having said that, my opinion is that the barebones K-2 is a lot more 
radio and a better performer than a K-1.  I have both and enjoy both, 
but feel the K-2 is a cut above the K-1 in every respect except for the 
fact that I like the audio of the K-1 better (don't know why that is, I 
just do).


So, either way you won't go wrong.

RE: [Elecraft] K1 problem

2006-08-06 Thread Randy Moore
Thanks for suggestions from several, both on and off the list.

With an ohm-meter, I checked that K2, K4 and K6 were in the correct state
with 20 selected, and they were.  I did a triple visual check of all the
20m-specific component solder joints on the filter board and they looked
fine.  But I re-heated all those joints anyway and voila!  It works again!!
So I guess one of those joints was marginal.  We'll see if this occurs
again. 

By the way, I'm loving the K1, but not quite as much as my K2!

[Elecraft] K2 Reading AGC Voltage and U2 Failure

2006-08-06 Thread W7is
I was getting ready to verify the AGC voltage on a one year  old working 
K2 when my probe slipped while trying to read the voltage on pin 5 of  U2.   
  The K2 locked up sending continuous dots and no buttons  function
 on the front panel. 
The dispaly locked up on the last frequency it was reading and the tuning  
dial
has no effect on it.   
 
Maybe I shouldnt have done this but I decided to try a master reset just  in
case.   Which didnt solve the problem ---   but the k2  did reset.  But its 
still
hung up but this time with a dash all the time rather than continous  dots.   
 
According to the voltage readings on U2 of the control panel, 
 pin 3 has only .27 volts on it. 
While pin 6 and 7 both read 3.8V.So it would appear that  the probe 
slipping
has caused U2 to fail?I can adjust the  agc threshold voltage for the 
proper
3.8V on pin 5.
 
 I dont have a spare LM833 on hand to be able to confirm thats  what 
happened but it would appear so.   
 
 
Am I the only one who has had the probe slip on U2 while trying to read the 
AGC Threshold Voltage?

Re: [Elecraft] Band Conditions

2006-08-06 Thread Brian Murrey
I worked LU5DYV in Argentina on June 10th, on 20m.

I did it with a Anttron Hamwhip on my Taurus while driving across I-70 in
Indiana.

The rig, was the awesome KX-1 at about 2w.  A few mins later I hear N5KY in
QSO all the way from Albequrque NM...he gave me an honest to goodness 569 on
my KX1 2w mobile.  He was running 500w  and was blowing my headphones off.
GREAT fist.

I would suggest if you want to work DX on 20m, you turn on the radio and do
some listening for a bit.  Seems like when it opens, it is really open...but
it may only last 20-30 minutes.

Re: [Elecraft] Considering K-1 or K-2

2006-08-06 Thread Stephen W. Kercel

Phil:

The noise blanker and audio filters are nice, but not totally 
necessary. As a CW guy you do not the SSB option. As a QRPer you do 
not need the high power option. Unless you have a special fondness 
for 160m you do  not need that. You can get by without an external tuner.


In other words, even a bare bones K2 will run circles around any other QRP rig.

The kit will cost you $600 and is worth every penny.

Re: [Elecraft] Considering K-1 or K-2

2006-08-06 Thread Mike WA8BXN
There ought to be a FAQ! With either rig I would suggest the built in tuner
option. The K-2 definitely is a higher performance radio, and bigger and
heavier. Also don't forget the KX-1! As for those other radios, if they
break, where do you get parts? I have a K-1 that got zapped pretty good by
lightning and I got it running again having replaced about half a dozen
components. Not sure that would be possible if it had been the FT-817 that
got zapped. Good luck on picking a radio, each has its strong points. I
suppose part of it is really deciding what your requirements exactly are.

If you just turn on your radio right now you may hear nothing but 
noise. As you say if you tune around for and hour you might hear 
something. But if your looking for a friend across country your not

-

Of course you have to consider the general propagation that is pretty
independent of the sunspots. 40 meters and longer wavelengths are "local"
bands in the daytime, thanks to lower atmospheric ionization caused by solar
radiation. 

I think this last cycle was my fifth sunspot maxima on the HF bands. My
first was the mega-cycle on the 1950's when I frequently chatted with South
American Hams on 10 meter AM phone running perhaps one or two watts into a
mobile whip on my way home from school in the afternoons in Southern
California. That cycle has never been repeated - yet. 

Of course, what's different during the sunspot minimum is that the MUF runs
much lower than during the maxima. Instead of reaching 50 or 60 MHz at times
during a maxima, the MUF might not get above 15 or 20 MHz many days during
the minima; sometimes it won't reach 10 MHz. On the other hand, geomagnetic
storms are much less frequent, so "black out" periods are pretty rare during
the minima. Of course, atmospheric QRN is lower on the higher bands, so when
the MUF is high, the problem of band QRN is much reduced. That's a major
reason why so much spectacular DX on wavelengths shorter than about 20
meters turns up during the maxima: a signal that's Q5 on 15 meters might be
buried deep in the QRN on 40 or 80. 

Another point is that propagation is more stable now. When sunspots are more
active, things change more quickly. Openings open and close much more
quickly. Now the bands change much more slowly and are predictable. If you
have a weekly sked with a buddy on a given band and time of day, you'll find
the signals much more consistent week in and week out now. Of course, if
you're trying to link up over a path that requires exceptional skip
conditions, you may be out of luck until things get more chaotic again with
the rise of the next cycle.  

But that's only the propagation that has been identified well enough to
study and predict. There are other modes that appear that still confound the
scientists to identify, much less predict, and which definitely do not show
up in the computer models. 

For example, I have experience with Marine CW communications in the 600
meter band (400-500 kHz). Some years ago a ship in the middle of the Pacific
heard an SOS on 500 kHz in the middle of the night. Sparky woke the Captain
and they immediately headed for the signal using the radio direction finder
all ships  carried then. After several hours of chasing the signal and not
being able to find anything, they finally got the whole story. The signal
was real. It was a lifeboat radio with survivors aboard, but it was in the
middle of the Mediterranean Sea halfway around the world and in daylight!
There was no way a 500 kHz signal running a few watts into a miniscule
antenna should have been heard more than a few miles in daylight or perhaps
some dozens of miles at night, but there is was, rattling the automatic
alarms half a world away. 

Also, the sunspot upswing tends to happen faster than the downswing. That
is, it won't be long before hints of future chaotic propagation heralding
the rise of the next cycle start appearing more often. So enjoy this period.
It can be as interesting as the peaks, in its own way.

[Elecraft] August NAQCC Sprint

2006-08-06 Thread Larry Makoski W2LJ
This Tuesday evening (Wednesday morning UTC time) will be the NAQCC 
Sprint for August.


This month, the Sprint will be held on 80, 40 and 20 meters. Two special 
certificates will be handed out this month.  The highest number of cross 
Mississippi River QSOs will be noted for the appropriate Eastern and 
Western operators.


The Sprint will run from 8:30 to 10:30 PM EDT, 7:30 to 9:30 PM CDT, 6:30 
to 8:30 PM MDT and 5:30 to 7:30 PM PDT or from 0030 to 0230 UTC on the 
morning of August 9th.  The recommended frequencies are:


80M - 3555-3565 kHz (Be courteous to FISTS operating on 3558 kHz)
40M - 7039-7050 kHz (Avoid W1AW on 7047.5 kHz)
20M - 14059-14065 kHz.

The exchange is as follows:
RST - SPC (State Province or Country) - NAQCC Nr.
(non-Members send power level in place of NAQCC Nr., e.g. 5W, 1W, etc. 
Be sure to add the W.)


Remember to mention the type of antenna you have used when submitting 
your log as there will be two separate categories - simple wire antennas 
and gain antennas, such as yagis, quads and periodics.


Also, remember the bonus multipliers that you get for using either a 
straight key or bug during the event. All entries must be postmarked or 
email dated before 2400Z on August 15, 2006.

RE: [Elecraft] K60XV help

2006-08-06 Thread Don Wilhelm
John,

The most likely thing wrong is that the K60XV is not properly plugged into
the RF Board headers.

I have 'been there, done that' many times.  It is difficult to see under the
board while plugging it in, but get your head down close to the board and
peer under it.  If the board is tilted when inserting it, the headers can
easily end up one pin off.  The connections to the RCA jacks are a bit tight
and make it difficult to get it right - pull the board up as high as you can
and then make it parallel with the RF Board before attempting to plug it
into the headers.

I work most of my DX when the bands are 'dead'. I don't band-hop much. I'll
pick a band - may favorite DX band is 20 meters - and spend an hour
listening to static if that's what's there while tuning across the band.
That's where I find a lot of interesting contacts. Much like 6 or 2 meters
when an opening hits, suddenly there will be a signal or two standing well
above the noise, and they're often long DX - sometimes long-path DX as well.
Sometimes we chew the rag for a while because he was listening to a 'dead'
band too. Maybe that happens more now because the guys looking for a
30-second QSO before jumping off to another station are punching the
band-buttons like crazy looking for a pileup or they've given up entirely. 


I exaggerated. On 20 I don't think I've ever listened to static for a full
hour. Long before then I've scared up a QSO somewhere . 


The other night I was listening to a very quiet 40 meter CW band. I'm
currently on a temporary antenna. It's what most would call a NVIS antenna
on 40. It's an end-fed dipole less than 20 feet up. Virtually all of my
contacts are along the west coast from my QTH near the Oregon coast. I
normally don't expect to work anything east of the Rocky Mountains. 


I called a brief CQ, and there was a reply just above the noise. Cool, I
thought; I always enjoy working a weak signal. It turned out to be N9DFM,
Dave in Minnesota, running 5 watts! So I cranked down my power from 100 to 5
watts and he copied me QRP as well. Not fantastic DX, I know, but a FB QSO
and over a 1,700+ mile hop I don't normally expect to work even when the
band is very active. And all on low-slung temporary antenna.
  
   Yes that is fun and 40 meters is where you will find activity at 
night if the noise is low enough. But this is not as good as it will get 
when conditions improve. And they will. Then you will work DX with a 6 
foot mobile antenna QRP.


   If you just turn on your radio right now you may hear nothing but 
noise. As you say if you tune around for and hour you might hear 
something. But if your looking for a friend across country your not 
likely to hear him now. In a year or two it will get much better.

[Elecraft] Elecraft CW Net Announcement

2006-08-06 Thread Kevin Rock


Good Afternoon,
   Sorry for the very late announcement but the power has been  
intermittent this weekend.  A tree must have broken a line in a remote  
location since it took them so long to fix it.  I arrived home on Friday  
evening only to have the lights go out about two minutes later.  They got  
the power up and running after about six hours but yesterday evening it  
went out again.  Life in the country can be interesting!  Good thing I  
have a camp stove and some water stored.


   Forty meters was fairly good during a contact on Thursday evening.   
Hopefully the same will be true later today.


   Please join us:
Sunday 2300z (Sunday 4pm PDT) 14050 kHz
Monday 0200z (Sunday 7pm PDT)  7045 kHz

Until a bit later today,
  Kevin. KD5ONS

Re: [Elecraft] Band Conditions

2006-08-06 Thread Brian Murrey
The bands could be better, they could be worse. I think the real knowledge we
have about propagation of radio waves is that it is always changing.

In the NAQP yesterday, I worked CA, FL, and ME on 20 meters, in the late
afternoon, with a homebrew fishing pole vertical, and my KX1 at about 3w.

About an hour later, I worked CA, NY, and FL with the same antenna and my
SW20+ at about 1.5w

San Diego is about 2200 miles from meboth QSO's were with stations in San
Diego.  I also worked San Francisco.

During NAQP the 20m band was buzzing with stations from all over.  At about
5PM I tuned around 40m and there were stations everywhere.

Keep trying Karl, maybe your antenna needs adjusted?

How about it folks.
Lets hear about your fun filled experiences!

Ron, wb1hga
"CW, an esoteric experience"








Ron:


I had 21 QSOs (19 QRP) on 15 meters between 1900Z and 2000Z 
yesterday. I admit that when the flux is 70, it is rare to have 15 
meter openings like the one that happened yesterday.


On the other hand, except for 0500-1100Z, 20 meters is practically 
always open from here in Maine to somewhere interesting.


There was 5W0 was on 40 m at about 0620Z on Sunday morning. He was 
calling CQ, and had few takers although he was a solid S8 in Maine. 
He gave my 5 watt signal a 599, but I suspect that is what he had 
programmed into his keyer.


Last night, 80 meters was extremely noisy, but I did work several 
stations west of the Mississippi on QRP.


Many hams besides me have observed what might be called the "contest 
effect."  A band normally seems dead, but somehow bristles with 
signals during a contest. One problem is that everybody assumes a 
band is dead and nobody calls. I suspect that another part of the 
problem during low flux is strong and fast QSB; the band has many 
brief openings on specific paths. For example, I might hear several 
California stations on 15 or 20 meters, but not be able to hear the 
W6WX beacon at all.


Yesterday, on 15 meters I could sometimes hear west coast stations as 
if they were across the street. A few minutes later they would fade 
into the noise, and a few minutes after that, they'd be back as 
strong as ever. This might account for the "contest effect."  When 
there are lots of contesters on, one hears somebody on those paths 
that are temporarily open. Since those spot openings come and go 
quickly, one hears a pretty broad sampling over time.

Nor does one have to wait 6 years either ... SS cycles typically rise a

noticable since we compare conditions to those at the minimum.  I 
suspect we will begin seeing improvements by this time next year, and 
major improvements by winter 2008.


Some prognosticators are predicting Cycle 24 will rival Cycle 19 (I was 
a new teen ham in 53 and thought it just stayed that way all the time!). 
 Others are not so sure.  I'm with the first group since my current 
life expectancy is slowly closing in on the length of a cycle at about 
minus one year per year (I hope!), and this may be the last full cycle I 
get to see (again, I hope!).

[Elecraft] K60XV help

Hi,

I just installed the K60XV on K2 #5312.  I did not receive "INFO 080"  
when first turned on.  After changing D19 to yes on secondary menu, I  
could not find the band.  I removed the board and replaced it after  
determining that the pins were inserted correctly.  THEN, I got the  
evil "INFO 080" when turned back on.


If the K60XV board is unplugged (still connected to phono plugs), K2  
is normal.


I have checked the values of C12 and R1: both correct.  The notch on  
U1 is facing the relay.   There are no obvious solder problems.


Any and all help greatly appreciated.

It sprang into life.

 

Today I built the 30m module (bit of a tricky install that one!).did the

Re-installed the KXAT1 and it is back to the --- display.rechecked the

I should check next?

How's that again? In the NA QSO party yesterday, both 15 and 20 
meters were in fine fettle. On 15, I worked stations as far away as 
the west coast. On 20 I worked Brazil and Russia. On a very quiet 40

Overall I had about 200 QSOs in 8 hours of operating. All this was

The bands are far from broken, and QRP is readily workable.

The only thing to be concerned about is when K>2 or A>10, working DX 
on QRP can become frustrating.


Anyway, one does not need to wait for the flux to come up. There's 
plenty of activity for QRPers right now.

   Do not re-align your K2 receiver, or re-tune the transmitter for 
another 0.1 Watt of output. Leave it alone because the bands are 
broken, not your radio. It will be very seldom that you hear 
anything much on 20 meters. And 40 meters is noisy right now.


   In a couple of months we should see the K index get active (a 
little) and the Flux will zoom up to 90. When that happens get on the air :-)


   You can get the Flux and K index from listening to WWV. At 18 
minutes after the hour a muffled voice gives you these current 
numbers. WWV is on 2.5, 5, 10, 15, and 20 MHz. They run 25 KW so 
you hear them even when conditions are poor!


   In about 6 years QRP will be a lot of fun.

[Elecraft] Band Conditions

2006-08-06 Thread Karl Larsen
   This morning the Flux was 70 and the K index was 0. This is "Sunspot 
Minimum" readings of the sun. What does this mean to a QRP Operator?


   Do not re-align your K2 receiver, or re-tune the transmitter for 
another 0.1 Watt of output. Leave it alone because the bands are broken, 
not your radio. It will be very seldom that you hear anything much on 20 
meters. And 40 meters is noisy right now.


   In a couple of months we should see the K index get active (a 
little) and the Flux will zoom up to 90. When that happens get on the 
air :-)


   You can get the Flux and K index from listening to WWV. At 18 
minutes after the hour a muffled voice gives you these current numbers. 
WWV is on 2.5, 5, 10, 15, and 20 MHz. They run 25 KW so you hear them 
even when conditions are poor!


   In about 6 years QRP will be a lot of fun.

Randy, there have been a lot of reports of 20m hetrodyne crystal failures on 
the KFL1-4.  Can you hear a good strong 22 MHz (+/- 10 kHz) signal in another 
receiver (with antenna wire looped near the RF PCB) when 20m is selected on 
your K1?

See you at the Huntsville, AL, hamfest two weekends from now.

Re: [Elecraft] Re: K1 construction time

2006-08-06 Thread Larry Makoski W2LJ
No, actually, I think 30 hours is just about right.  If you're an 
electronics assembler for a living, it might take a bit less; but 30 
hours is just about what I spent on mine.  Of course, I double check 
everything before soldering; and I solder each component one at a time.  
I figure that a) I don't want to see any smoke and b) if I have to 
troubleshoot, at least let it be for something that wasn't my stupid 
mistake!


After all, the goal is to end up with a working radio; not to end up 
with a working radio in the shortest amount of time!  We can go to the 
FDIM building contest for that!

Re: [Elecraft] A Good Day With The KX1

2006-08-06 Thread David Elliott

Paul,

Using a mobile antenna like the Hamstick on a vehicle is one of the easiest 
ways to have fun portable with a QRP rig.  If you didn't do it, try using a 
few (3 or 4) relatively short (20 feet or so) radials from the base of the 
antenna.  I use insulated wire and just let them fall where they will.  You 
will be amazed at the performance enhancement.

Subject: [Elecraft] A Good Day With The KX1



The YL and I had a good day at the National Zoo
in Wash. DC  Set up the KX1 in the Parking
Lot with a 40 meter Ham Stick and made contacts
with the KX1. I was excited about that because I
have made very few contacts in the past with the
KX1.

I have not hooked any cables up to the car
battery yet but a few months ago John Harper had
told me about the 11.1 V. LiPoly battery and used
it today. The KX1 was putting out 3.5-4 watts so
that made it pretty easy to have some contacts.

We parked by an Island of grass under a shady
tree and set up our 2 folding chairs with a shelf
on the right side of the chair so that made
operating a breeze. The Antenna was in the clear
and set up in the center of the rear deck of our
Impala.

[Elecraft] Re: K1 construction time

2006-08-06 Thread Paul Huff
Hi Cathy,

I built my K1 back in 2004 and kept very careful records of my construction
time.  It took me 30 hours for my 4-band version without the ATU.  That included
everything from opening the shipping container to the final cover screw.  It
also included the set-up and clean-up times for each building session that are
required in my situation because I don't have a place where projects can just be
left out.  I do have other kit building experience but the K1 was my first "big"
project.  I'm sure that it can be built in a lot less time but I tend to go slow
and stretch it out.  I probably enjoy the building as much as I enjoy the
operating.  So it's kind of like eating a good dessert - you can eat it fast or
slow down and enjoy each bite!
