5. 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.  

 

Hope everyone was able to enjoy Field Day this year.  The bands were crammed
with traffic!  The weekend also kicks off Lightning Safety Awareness Week.
(Held off on this topic so as to not jinx the weather for Field Day!)

lightning protection in a coaxial cable feed line?
