Things this week:  

1.        Missing power cable

A few weeks ago Mike, KE8BGJ, brought in a Kenwood HF transceiver to check
out in and left behind the power cable. It is red with a 6 pin molex
connector. If you see it or know where it is please give it to Tom or
George.

 

2.        Upcoming Activities 

Fort Wayne Hamfest November 17-18

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,
subelement 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.  

 

This is quiz 13 for those keeping count.  That's a full quarter! To
celebrate this mini-anniversary we have a special topic near and dear to all
our hearts, vacuum tubes.  The vacuum tube, or thermionic valve, was
patented on 16 November 1904 by John Ambrose.

 

T6B01 What class of electronic components uses a voltage or current signal
to control current flow?

A. Capacitors

B. Inductors

C. Resistors

D. Transistors

 

G6A12 What is the primary purpose of a screen grid in a vacuum tube?

A. To reduce grid-to-plate capacitance

B. To increase efficiency

C. To increase the control grid resistance

D. To decrease plate resistance

 

E7B09 Which of the following describes how the loading and tuning capacitors
are to be adjusted when tuning a vacuum tube RF power amplifier that employs
a Pi-network output circuit?

A. The loading capacitor is set to maximum capacitance and the tuning
capacitor is adjusted for minimum allowable plate current

B. The tuning capacitor is set to maximum capacitance and the loading
capacitor is adjusted for minimum plate permissible current

C. The loading capacitor is adjusted to minimum plate current while
alternately adjusting the tuning capacitor for maximum allowable plate
current

D. The tuning capacitor is adjusted for minimum plate current, and the
loading capacitor is adjusted for maximum permissible plate current

4.        Projects

Bring something to work on.   What you building?
