Things this week:  

1.        Hamvention - what did you see or get?

Come tell stories

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

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.  

With the excitement of the Dayton HamventionR just over, the quiz looks to
operating practices for this week's questions.  Let's welcome the radio
community to the region with exemplary operating practice!

T4B14 Which of the following is a use for the scanning function of an FM
transceiver?

A. To check incoming signal deviation

B. To prevent interference to nearby repeaters

C. To scan through a range of frequencies to check for activity

D. To check for messages left on a digital bulletin board

G4D10 How close to the lower edge of the 40-meter General Class phone
segment should your displayed carrier

frequency be when using 3 kHz wide LSB?

A. At least 3 kHz above the edge of the segment

B. At least 3 kHz below the edge of the segment

C. Your displayed carrier frequency may be set at the edge of the segment

D. At least 1 kHz above the edge of the segment

E4D03 How can intermodulation interference between two repeaters occur?

A. When the repeaters are in close proximity and the signals cause feedback
in the final amplifier of one or both transmitters

B. When the repeaters are in close proximity and the signals mix in the
final amplifier of one or both transmitters

C. When the signals from the transmitters are reflected out of phase from
airplanes passing overhead

D. When the signals from the transmitters are reflected in phase from
airplanes passing overhead
