[Elecraft] K2 menu issue

2017-09-16 Thread IZ0DIO via Elecraft 
I've a problem using my K2/100 with KAT100: every time I switch off K2 the
ATU menu selection is not stored and switching on again the ATU selection is
always on CAL, so I've to change it to AUTO in order to use KAT100. 

This is a very annoying situation: any suggestion?

Thank you in advance

IZ0DIO - Giorgio

[Elecraft] Elecraft CW Net Announcement

2017-09-16 Thread kev...@coho.net 

Good Evening,

The weather has turned.  It may be the start of the rainy season 
tomorrow.  At least the forecast has no breaks in the showers for the 
'known' future.  The sun has gone back to a more quiet state; at least 
until that big sunspot rolls around again.


Please join us tomorrow on:
   14050 kHz at 2200z Sunday (3 PM PDT Sunday)
    7045 kHz at z Monday (5 PM PDT Sunday)

    73,
    Kevin. KD5ONS

Re: [Elecraft] P3: Something I find handy

2017-09-16 Thread MaverickNH 
Very interesting! What information might this add to a K3S/P3 setup that has
a remote ATU at antenna base?

Re: [Elecraft] P3: Something I find handy

2017-09-16 Thread Richard Fjeld 
FWIW,
I have posted something about this before, and this will be my last, but I want 
to pass the word again.
I have the MFJ-212, but other similar devices should work also. It makes having 
a P3 even better.

Before I bought my P3, I had been using a MFJ-212 MatchMaker to help me adjust 
my external tuner/matchbox.   It applies a pulsing white noise across the 
spectrum. I have my P3 display the K3 frequency in the center of the screen.  I 
was pleased to see that when the P3 is set to 200 Khz bandwidth, and as the 
tuner reaches a good match at the frequency of  the K3,  the pulsing white 
noise forms the shape of a ‘V’ on the screen or monitor.  In a way, it  becomes 
 a piece of test gear.

The shape of the Vee can be adjusted by moving the controls on the manual tuner 
until the best match is achieved. Ideally, the base of the Vee will bottom at 
the center of the screen.  The shape or ‘Q’ of the Vee  can reveal problems. 
Also from one day to the next, without touching the tuner, the Vee may be as 
far away as 40 KHz or more  from the K3 freq due to changes in the antenna 
system (rain, frost, trouble, etc.) It gives a visual glance at the condition 
of my antenna system.

After making a change to the antenna or open wire feedline, and I need to find 
the new tuner settings,  I can watch as the color of the waterfall changes to 
help me see progress toward finding a match until the Vee begins to form.  If I 
get a proper looking Vee, I don’t need to check the SWR because experience has 
shown it will always be a 1.0:1. I do glance at the SWR indicator on the K3 to 
verify it as I transmit.

It can also  show the behavior of my external ATU after it has tuned. (Keyword 
is external to the radio). I have only had one ATU to look at so far, and I 
hope others tune better.

The best part is, I can tune without transmitting and while listening. No 
hurry, no worry.  I can even  ‘tune up’ on a QSO while listening to what is 
being said.  Once again, FWIW.

Rich, n0ce

Possibly Fred. I didn't specify because by the 1980's there were several newer 
types with the same features - some even solid state! They all went away when 
the 500 kHz distress frequency was abandoned in the 1990's.

Re: [Elecraft] P3: Vertical Lines for display question

2017-09-16 Thread Dave Cole 
As always Jim, you have something that helps!  THANKS...  Let me absorb 
your presentation on using the P3.  You are using it for almost exactly 
what I am planning...


I have been hoping to avoid adding vertical grid lines, but maybe it is 
time to start that using GIMP...  If only the P3 did that...


Thanks again Jim!

Hi Dave,

Take a look at the screen grabs in 
http://k9yc.com/P3_Spectrum_Measurements.pdf


These were done two ways. The ones without the SVGA were saved from the 
P3 Utility. Those with the SVGA were saved to a USB thumb drive via the 
SVGA menu.  These data were all obtained by accumulating peaks on the 
signal. Before saving the screens, I used the cursor to points along the 
curve on both sides to document the frequencies and levels and wrote 
them down. Then I saved the screens.


Note also that there are small calibrations along the top of the screen, 
and that these are sub-divisions of the scan width. Using graphics 
editing software, it's possible (not easy) to turn the screen grab 
negative so that the background is white and the traces are some color 
dark enough to print. When using these calibrations, it helps to set the 
scan width to a the smallest value that contains all the data and that 
makes these calibrations a convenient scale. When printing the graphics, 
it helps to scale the image so that the spacing between calibrations is 
the same or close to whatever ruler is available. Also, decimal rulers 
help.


The edited graphics can be printed, vertical lines drawn, and points 
picked off with an architect's or engineer's scale. I've done this with 
some P3 data, and also ARRL Lab data for which data files were not 
available. Older engineers (those of us trained 50 or more years ago) 
learned these techniques (and a lot more) in our freshman year.  Data 
for Fig 2 in k9yc.com/TXNoise.pdf was obtained by applying these methods 
to the plots on Pages 1 and 2.


If this sounds like a lot of work, you're right. Which gives you an idea 
how much time I put into producing those reports. :)

It is true that a little bit CAN go a long way. Back in the 1990s when I was
working on ships with MF CW gear I had the opportunity to share coffee with
a radio operator and his captain who had spent hours circling in the Pacific
looking for the source of an SOS on 500 kHz. It turned out to be a
hand-cranked lifeboat transmitter in the Med.! They were chasing a phantom
signal at the antinode half way around the world. The emergency transmitter
ran a couple of watts at best into a very limited antenna hung by a kite or
balloon over the raft.

Hello Don,
Thank you for the answer.  I am looking to impress a grid structure on 
the P3, as opposed to some lines I need to move.  I want to be able to 
document exactly how wide something is signal wise, by taking a snap of 
the signal, then looking at it with my computer.  I had not thought 
about the markers, thanks for that.  That will do if I can't locate a 
way to actually impress a grid on the output of the P3.

There are 2 thin Markers that can be moved about on the spectrum display

I think the vertical lines you are asking for can mask those markers.

We've had these bands in Europe for years and AFAIK nobody uses voice
modes. The IARU R1 bandplan suggests a maximum bandwidth of 500 Hz.
