Things this week:  

1.        Were you prepared for the tornadoes?  + HARA

Were you ready?  If not, lets discuss what you should have ready if the need
arises in the future.

Here are some video & photos of the damage to HARA

2.        YAGI Antenna workshop part 5 - returns June 6 - NEXT WEEK!!

Join us for a Build-It: Yagi Antenna Workshop. This multi-session series
will focus on yagi antennas the vhf/uhf frequency bands, including designs
for ATV and EME. But HFers will also gain by attending.

This series will start with a good overview on antennas. The next session
will look at the function of a balun, the different types, and actually do
some testing of baluns. We'll look at how to select your build-it yagi, and
present some easy-to-assemble options for the driven element. For the
hands-on building, you can build your own, build with a group, or be an
observer.

The final sessions will include tuning and testing the yagi antennas, and if
there is interest, could include an antenna gain measurement event to verify
how well the antennas perform.

This 7 session course is planned to run every other week and will run for 7
sessions.  

Here is the proposed schedule:

Many thanks to Joe Burke, WA8OGS, and Mike Suhar, W8RKO, who have put this
together.

3.        Projects

Bring something to work on.   What you building?

4.        License Exam Questions of the week

One question is drawn from each of the three question pools. Steve, AE8AT,
is providing these questions.  Thanks Steve

Answers are at the end of this email.

We received a question regarding the strange mix of letters and numbers that
begin each question.  Every exam question has a unique combination of
letter-number-letter-number.  The first letter is a T, G, or E to identify
the question pool: Technician, General, or Extra.  Next is a single number
representing the category, for example, category zero is safety in all three
exam pools.  The first letter-number pair is called the "sub-element".   The
second letter is a "group" containing related questions.  Example,
sub-element G8 is Signals and Emissions, with group C of that sub-element
being Digital Emission Modes.  The questions are numbered sequentially:
G8C01, G8C02, and so forth always with a 2-digit number at the end.  The
question identity is included in case of a typo or some "help" from
autocorrect obscures either the question or the answer.  

Since we had a little gathering of our ham friends in town recently, there's
a chance some of you might have come home with new electronic components.
(And if you didn't, congratulations!  You have less to explain.)
"Electrical components" is a subelement of the question pools and the topic
