Re: [Elecraft] OT James Clerk Maxwell

[jrquark via Elecraft]

I have often recommended Daniel Fleisch’s book, A Student’s Guide to Maxwell’s 
Equations, to my students.  In it he credits G. F. FitzGerald, Oliver 
Heaviside, Oliver Lodge, and Heinrich Hertz for simplifying Maxwell’s equations 
to the few that we often see today.

Good Evening,

   I could not find an open space to run the twenty meter net. The forty meter 
net started when the CQWW contest faded away. There was QSB on everyone I 
worked.  Those farther east had slow waves.  KG7V is just across the Columbia 
River from me (and a little up the coast) had a fast flutter from S2 to S5.  
K1SW was able to check in again with his KX2 running 12 watts.  S0 to S3 but 
with repeats I got more information.  W0CZ had a strong signal but could not 
hear me.  His S5 to S7 signal was easy copy.


  On 7047.5 kHz at z:

K0DTJ - Brian - CA

K6PJV - Dale - CA

W6JHB - Jim - CA

KG7V - Marv - WA

W0CZ - Ken - ND

K1SW - Dick - CT


   I lost the use of my keyboard a little earlier today.  After two keyboard 
changes and a few reboots I determined the hardware was most likely not the 
culprit.  As I was switching keyboards I held down a key and a few characters 
appeared.  Very slowly.  So I queried the Ubuntu site and found 'slow keys'.  I 
dove into the settings and turned it off.  Seems you can turn on this feature 
if you hold the shift key down too long.  You learn something new each day.  
But for a while it was like Bach's "Rage Over the Lost Penny".


   Until next week stay well,

   Kevin.  KD5ONS

Great Image, Walter, et al.  I processed it a bit for clarity and placed it at 
the top of my Ham Radio Gallery… link is below.  Click on the image for a full

Re: [Elecraft] Suggested enhancements for K3

[jrquark via Elecraft]

Great Ideas!  May I suggest, in the name of ‘feature creep’, a suggestion?  So, 
have the K3 or K3s dial up your cell phone where you can program specialty ring 
tones for all sorts of “mission critical” events.  This will surely get our 
attention while in the heat of battle for another 59 contact.  Or not!

Re: [Elecraft] Purpose of this group

[jrquark via Elecraft]

Yes and yes, plus many of us are quite practiced in using the delete key.

I own a K3s and I have no difficulty in skimming through the comments that are 
beyond my interests.  But, I have found interesting, informative and 
instructive topics, often not related to my K3s.

Your milage may differ…

Re: [Elecraft] Can anyone share a picture K3 with KPA1500

[jrquark via Elecraft]

Hi Martin;

When I received the requested photo of a K3 and a KPA1500 from Elecraft, I 
realized too late that the amplifier was a KPA500, sorry.  Margaret and Madelyn 
from Elecraft noticed the error and sent me a photo that is correct, whew!  
But, this reflector would not publish it, since it was a bit too large, so I 
uploaded it to my SmugMug photo account.

Here is a link to that photo –> 
https://jrquark.smugmug.com/Amateur-Radio-Stuff/n-gj25kF/i-RXwvZmb/A 


This link should you allow you to download it, if you require.
