Things this week:  

 

1.        Clean-up

This week we will continue cleaning up and deciding what to get rid of at
the DARA Auction.  Please come help

2.        HF - UHF Antenna Analyzer UPDATE  

Phil is working on the software to match the new board

3.        ** 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.  

 

The quiz this week has an interesting topic, errors.  No, not the error
correction in digital communication.  All the questions this week are in the
errata, although you are receiving the corrected versions - only the best
for the DARA Repeater audience!  Interesting side note for those considering
upgrading to General, the question pool changes on July 1.  The new
questions were published on January 4 at www.ncvec.org, and then revised on
January 6.
