[Elecraft] Why ESSB and AM?

2012-09-23 Thread Bill Frantz
When Don wrote the paragraph quoted below, I started to think 
why I would want to use one of these modes. AM doesn't seem very 
likely except as a demo.

But ESSB might be useful to transmit a wide-band, high bit rate 
digital mode via a computer sound card. Those sound cards have 
at least 15KHz bandwidth, which would need to be reflected in 
the transmitter (and receiver) bandwidths. That amount of 
spectrum would be reasonable in bands where FM is commonly used.

I find the regulations for 160M-10M confusing as to the maximum 
bit rate* and bandwidth permitted, but on 6 meters, the 
authorized bandwidth is up to 20 kHz with a maximum baud rate of 
19.2K baud/second.

Cheers - Bill, AE6JV

* The regulations speak in terms of maximum baud rate, but you 
can send more than one bit/baud, if you have enough bandwidth.

Re: [Elecraft] KPA500 Problem

2012-09-23 Thread Richard Squire - HB9ANM
That's right, Fred and Mike - This is exactly what I have been mentioning
ever since I got my KPA500 a year ago. It only occurs when BND CHG is set to
STBY, which I think is safer. Elecraft was able to reproduce it and said it
would be corrected in a future release. The bug is supposed to be on the K3
side.
IMHO, this is important to all, rather than AM (seldom used) and ESSB (I'd
never do that!)

So if this is a known issue that's been present for a year in the life of a

Don't worry, John, you can still use the K3 buttons as usual to change bands,
but I would still recommend setting BND CHG to STBY on the KPA500 for safety
if you are using a manual tuner.
Glad to see the issue is now receiving so much feedback!

Greetings to everyone that helped with suggestions on my issue.

 

The problem has been found the - mic has gone bad.  The rig transmitted in
digital modes, and CW with a keyer.  

 

I took my rig over to a buddy that has a K3 and we hooked it up in his shack
and narrowed it down to the handheld mic.  Rig transmitted fine when we
hooked up another mic.

Re: [Elecraft] Why ESSB and AM?

2012-09-23 Thread Joe Subich, W4TV

  ESSB might be useful to transmit a wide-band, high bit rate
  digital mode via a computer sound card. Those sound cards have
  at least 15KHz bandwidth,

ESSB is limited to 4.0 KHz but is not available in digital modes
(DATA A or AFSK A).  While ESSB might be useful for those modes in
which panoramic (click in a 2.5 to 3 KHz wide waterfall) operation
is the norm, nearly every transmitter has an in band noise pedestal
(broadband noise) the width of the transmit filter that is only 60
to 80 dB below the transmitter's PEP output.

By the way, in the K3 when the ALC is adjusted for 4-5 bars and the
PWR control reduced to 25 watts or so for PSK31, that noise pedestal
is 80 dB relative to 25 watts  In the conventional rigs where the
power control is run wide open and the audio drive (mic gain) set
for no ALC, that noise pedestal is 60 to 80 dB below the *FULL POWER*
level as the IF stages run wide open providing maximum amplification
of the broadband noise.

[Elecraft] Elecraft CW Net Announcement

2012-09-23 Thread kevinr
Good Morning,
It is easy to tell we have entered autumn.  When the week began it 
was in the mid 70s.  Now it is in the mid 50s.  Trees are changing color 
and a few have begun to lose their leaves.  Spiders are everywhere.  As 
I am cutting wood I try to avoid the largest webs but inevitably I get 
one square in the face.  I have been hearing the elk and coyotes most 
nights.  They and the deer are exploring the areas I have opened up with 
my logging.  They like the easier access to water and to a cozy spot to 
sleep.  Propagation was up and down this week.  Let's see how it goes today.

Please join us this afternoon and evening.

1) Hail signs  (first letter or two of the suffix of your call)
2) NCS help  (as well as QSP/QNP relay help)

Sunday 2200z (Sunday 3 PM PDT) 14050 kHz
Monday 0200z (Sunday 7 PM PDT)  7045 kHz

Stay well,
   Kevin.  KD5ONS

Re: [Elecraft] K3 power output problems (partially fixed!)

2012-09-23 Thread Mark n2qt
As an update, (for all those following this thread with bated breath)

It looks like the problem of being unable to get full power out on the bands
below 17M, and the inability to do a TXGain calibration, was due to some
issue with the configuration of the ATU.  I set ATU to not installed and 
then
back to installed and power output came back up.  In addition when the
ATU is enabled and used to tune the 50 ohm load, the SWR after tuning
is 1:1.  (those who are following this will remember that originally tuning
made the SWR worse).  My idea of a loose connection appears to be wrong.

Now, the remaining problem is that the Current Display does not indicate the
current actually drawn.  The display 'saturates' somewhere around 3 amps or
so. (It appears to read sensibly up to that level, and then flattens out as 
power
is turned up).

I'll ask Elecraft Tech support for guidance on this one

I'm hoping to use the rig in the upcoming CQWW, so if there anything amiss,
it's sure to show up then.

 Emne: [Elecraft] K3 and MicroHam USB 3 issue
 
 I am going to send this out to both reflectors, Elecraft and MicroHam because 
 I am not sure where I have set up the system incorrectly. The system does 
 work intermittently and I have had successful QSOs with it on both CW and 
 digital modes.
 
 Setup;  K3, MicroHam USB 3, Y cable to ACC to USB 3 and Yaesu Quadra amp, new 
 Asus PC running 64 bit win 7 O/S with 12 gigs of RAM.
 
 Issue: I have intermittent performance with the USB 3 and my k3. At times 
 when using the device with FLDigi software the transceiver ends up locking up 
 on transmit and I usually have to exit out of FLDigi to stop the transmit 
 cycle as none of the buttons will work. This has happened in all fldigi 
 digital modes but is most prevalent during CW.
 
 I am also very uncertain about the knob position on the front of the USB 3. 
 Sorry but I can't find where the position should be in the manual. Plus I 
 cannot seem to get five bars on the ALC meter of my K3 no matter what I try.
 
 I am not sure if this is a K3 or USB 3 setup issue. I need a little help. It 
 does work about 50% of the time.
 
 Thanks,
 
 Keith

Re: [Elecraft] Why ESSB and AM?

2012-09-23 Thread Bill Frantz
I am digging to the bottom of the barrel for reasons to have a 
broad transmit bandwidth.

I don't think the high speed digital mode I'm thinking about has 
yet been invented, but one of the purposes of amateur radio is 
to expriment with new modes. I see such a mode as being useful 
for meteor trail scatter propagation. I think you could send an 
entire exchange segment (called station, signal report, and 
transmitting station) in under 10 milliseconds. That speed would 
allow several QSOs during the 1-3 second lifespan of the ionization.

With forward error correction in the protocol, the software 
could calculate the signal report based on the number of wrong 
bits received and the signal strength, the 5 and the 9 of a 
conventional SSB report.

With the mode filling the whole bandwidth ala PSK31 filling the 
31 Hz bandwidth, I don't think the 80 dB noise pedestal is a 
significant factor. But I certainly could be wrong. (It wouldn't 
be the first time.)

As a rag chewer at heart, that kind of QSO isn't quite my cup of 
tea, but it might appeal to the people who enjoy WSJT moon 
bounce. Amateur radio is a very big tent.

Cheers - Bill, AE6JV

ESSB might be useful to transmit a wide-band, high bit rate

ESSB is limited to 4.0 KHz but is not available in digital modes
(DATA A or AFSK A).  While ESSB might be useful for those modes in
which panoramic (click in a 2.5 to 3 KHz wide waterfall) operation
is the norm, nearly every transmitter has an in band noise pedestal
(broadband noise) the width of the transmit filter that is only 60
to 80 dB below the transmitter's PEP output.

Easy fix.
It just takes discipline.

Don't click on anything in an email, even if it says it's a picture of 
puppy's and butterflies from your daughter/grand-daughter. IT Security 
types have been saying this for years, but some people think it doesn't 
apply to them or their anti-virus/anti-malware/anti-phishing software 
will keep them safe... to click with impunity.

All of these programs run on virus/malware definitions you receive from 
the provider.
They are ALWAYS at least 12 hours behind on new virii/exploits, and 
that's the companies who're paying attention.

Re: [Elecraft] HELLO

2012-09-23 Thread Phil Hystad
Actually, either Google Chrome or Opera is superior to Firefox as a browser.  
Firefox has not kept up with changing times and performance.

On my Mac, the fastest browser is Apple Safari but Chrome comes in as a 
reasonably close second and then Opera.  And, all of these blow the doors off 
of Firefox.  And, obviously there is no IE on my Mac so that is a non-issue.

But, at work, corporate policy (which I violate every day) is to use IE and it 
is incredibly slow despite the fact that I have a very fast PC.

Both Chrome and Opera are available on a Windows PC too and they are much 
better then IE or Firefox.  My favorite for my at work computer is Opera.  
Since we do a lot of HTML5 based web application development, IE is not even in 
the running as a test platform and we rely on Opera and Chrome.  Just go to the 
site:  html5test.com and measure your favorite browser's HTML5 support.

Oh, Safari is available on Windows but that is not a good choice.  Safari 
screams on a Mac but it is stuck in the slush on a Windows box.  Safari is a 
web-kit based browser and so is Chrome and I think possibly Opera and just 
about every other browser on the planet.  Firefox is of course based on Mozilla 
Gecko and IE is based on IE junk.

[Elecraft] CW QRP

2012-09-23 Thread Tony Castellano
I just worked V73NS, Marshall Islands, on 15 meters using my K2 running 4.7 
Watts to a OCF dipole. My QTH is in ENY, near Poughkeepsie, NY. There were 
quite a few stations on the frequency, but the K2 got through.
This makes CW QRP country number 160 with my K2 since I first joined the 
Elecraft family one year and 3 months ago.
My best DX was Hawaii running 100 mW to the OCF dipole for 50,000 miles per 
Watt.
My country number 159 was Swains Island on 12 meters.
A good friend who owns a KX1, K1, K2, K3 and KX3 got me interested in Elecraft. 
Since I built my K2, I built a K1 and another
K2 for my wife W1ALI.
I also own a KX3 which is a great rig, but I still like to operate the K2. I 
might add that I don't own a mike and work only CW.
So don't count out the K2.

Thank you Elecraft for great products.

[Elecraft] Balun Ground Connection

2012-09-23 Thread Jim Harris
Several days ago I responded to someone about a situation with their antenna 
and balun.  I basically said my experience with an antenna at my station was 
that by connecting the ground on the balun to my station ground the SWR were to 
25 and I had operated with the ground disconnected.  I received several 
unsolicited remarks about my antenna system implying there were serious 
problems and that I should solicit help.  I had said I would do some more 
checking.
I connected my SWR meter through a one foot RG-8X coax to the SO-239 connector 
on the balun.  Thereby eliminating all the station with it's coaxes and grounds 
leaving only the antenna, 400 ohm ladder line and balun connected.  At 14.080 
Mhz I measured SWR of 5.1:1.  I connected the ground lung on the balun directly 
to the outside ground with four feet of wire and measured an SWR of 9.6:1.  In 
relative terms of SWRs that is near the 25 that I had mentioned earlier.
I disassembled the balun and checked it and all wiring and connections and 
found no problem.  I reassembled the balun and retested with the same results.  
My opinion is the ground and associated wiring, when connected, is forming part 
of the antenna system thereby changing the SWR as would any metal object 
attached to the antenna system.  Seems simple enough in a practical world.
Therefore, it is my conclusion there was and remains no issue with my earlier 
statement concerning my experience.  Yes, I would like to see a lower working 
SWR with the antenna system and the ground disconnected and I am working on 
that issue..having a different antenna to install this week.  But that is a 
different issue from the original.
I realize people are seriously trying to help.  It would also seem that when 
help is not specifically solicited none should be offered.  That will be my 
position in the future on this reflector.  The Kool-Aid is too strong for me.

Take pride in the USA. 73

Re: [Elecraft] CW QRP

2012-09-23 Thread stan levandowski
Tony, congratulations on your consistent success with QRP operations. 
One thing you did not mention is the infinite patience and self control 
you apply to your QRP operations.  You realize the signals *are there* 
and you stalk the bands and wait out the gods of propagation, when the 
less hardy ops might abandon the shack for the family room, a bag of 
chips and a cold brew..which is exactly where I'm headed right now.

(P.S. to the Elecraft family -- the 4.7 watts is because this guy has an 
incredible hangup with  not violating the 5 watt limit for true QRP 
ops.  He keeps it well below to account for measurement error.  When he 
says he's QRP.he really means it!).

I seem to be having an interesting situation here. When I have the KPA500
plugged into the ACC port my K3 won't stay on 2 meters. It will flash the
frequency and then drop down to 6 meters. Is this a known problem, or have
I turned up something new? Oh, this is with the KPA500 powered down. Didn't
think to try turning it on, just unplugged the ACC line.

[Elecraft] [K1] Filter question..

2012-09-23 Thread Gil G.
Hello,

Please have a look:

http://radiopreppers.com/images/K1_FL3.png

This is my K1 on FL3. Looks similar on FL2, better on FL1.
How do I bring it to center on 600Hz?

Thanks,

Gil.

Gil,

You adjust the RX BFO trimmer C20.  Check that RFC1 is actually 33 uHy, 
it is frequently exchanged with RFC2 while is 22 uHy.  If your color 
acuity is not sufficient to clearly determine the difference between the 
red bands and the orange, ask a female for assistance.

I would suggest that you will do better using an audio spectrum analyzer 
in a line display mode rather than a waterfall.  You can more easily 
determine the center of the passband

Once you have set the center of the passband to your desired center 
frequency (also set the ST P menu to agree), turn thee TEST/OPER switch 
on the bottom of the RF board to TEST.  You will find a spike at your 
transmit pitch.  Adjust C13 to place that spike at the same frequency as 
your ST P setting.

Ummm ... not always helpful.  I have no color vision, I've showed 
resistors to my wife who tells me, Well that first one is sort of 
salmon-ey maybe closer to peach.  Salmon is a fish, peach is a fruit. 
Colors are red, blue, green, orange, yellow, violet ... you know, like 
in preschool.

Fred,

That hits right at home base.  Yes, these women have lots of names for 
those in between colors, and paint manufacturers amplify that by a 
factor of 10.

My wife tells me that I only had 8 crayons in my box when I was a kid, 
but that is sufficient for reading resistor values.

I have compared resistor color bands on some older carbon resistors that 
I still have in my junkbox, and I can say for certainty that the colors 
are not as saturated as they used to be, so it is not all my eyes (which 
admittedly are not as great as they used to be).
RF Choke bands are about the same as the resistor bands.
