I was inspired by this:-

Sorry!
Syms. 

Syms,

Thanks!  Wonderful.

In all seriousness, I would suggest we treat the newbies with a little
more patience.  It isn't easy starting out in this field.  I know these
folks will not become your customers, but they might someday be mine.

Your code says newsgrouop. I always thought that
we spelled things the same in morse and in english.

I got my license fifty years ago next month but it
has been a long time since I received code.

None,

I can proficiently miss-spell at close to 18 WPM!

My wife and I got our licenses not long after October 17, 1989...

The Loma Prieta earthquake fault line is ~ 1.5 miles due south of my house.

I didn't get home for 12 hours, and then once home, the secondary
faulting and collapse of roads and bridges left us alone for five days.

No electricity (no water, no heat, no A/C).

I just told the kids it was an extended camping trip (kerosene lanterns,
picnic table in the garage, along with the white gas camp stove).  My
wife's parents sent by UPS bottled water, tp, and some other incidentals
(remember UPS and FedEx are allowed through to deliver in a disaster
zone, and they will deliver if they can!).

1 in 5 of my neighbors lost their homes.

We just lost all the dishes.

My wife's description was "first the wall hit me, then the floor hit me,
and then the wall hit me again."

So, a ham license had been on my list since I was 14, and I finally
learned the code, and got it.  My wife got the "tech Plus" no-code
license (now code is not required for any license class).

Where we live, we get 'Biblical' proportion disasters: fire, flood
(mud-slide), windstorm (127 MPH this last January), snow (since it
hardly ever snows, this can be a disaster), earthquake, ... let's see,
so far no plague, and no pestilence.  Maybe next year?

Just remember:  the first thing to go out in ANY emergency, is the cell
phone system.  The Department of Homeland Defense strongly recommends a
ham license, for anyone serious about being ready for a disaster (or
working with disaster response professionals).  The DHS has provided
funds for local repeaters, training, etc.  They certainly recognize a
good thing when they see it.

Hams aren't stupid, we know we get our many MHz of spectrum at the
pleasure of our country, so many of us actively give back by
volunteering for emergencies, and supporting our local agencies.

In my "ham life" I have trained people to be professional communicators
in the event of an emergency for Santa Cruz ARES, and I have volunteered
for the County Sheriff's Department since I was licensed as a "Net
Command" (what they call their radio dispatch for an "incident").

I encourage everyone to think about a ham license, anywhere you are in
the world, as when all else fails, we get through.

(typical of what hams do every time the lights and phones go out)

Austin,

It's great the things that you do outside Xilinx (also).  I just feel
for anyone trying to understand your dots and dashes since you
corrected your "neusgrouop" to "neusgruop."  :-)

Your wife's description of that quake was hysterical!
