[DARARepeater] TNG Thursday September 26

[Mark Erbaugh]

*PLEASE if you are having any COVID, RSV or FLU symptoms DO NOT come to the
clubhouse.*

*TNG – Thursday, September 26, 2024*

DARA Clubhouse, 6619 Bellefontaine Rd. Dayton, OH 45424.  The meeting
begins around 7pm.

No special presentation this week.

DARA/TNG is offering a three Saturday afternoon hands-on class on 3D
modeling starting this Saturday, September 21, 2:00pm at the clubhouse.
Bring your computer and learn hands-on how to use popular 3D modeling
software:

   - OpenSCAD (9/21)
   - FreeCAD (9/28)
   - Fusion 360 (10/5)

The 9/21 class was well attended. Each class is relatively stand-alone, so
even if you missed last Saturday feel free to attend either or both of the
remaining two.

If you are planning on attending this 3D modelling class and would like to
install the software before the class, feel free to bring your computer to
TNG and someone will be available to help you.

*Advance Notice*
There will be a special TNG presentation on *Wednesday*, October 30 at
7:30pm. Joe Eisenberg, K0NEB, will give an in-person presentation on kit
building. FWIW, the first forum I ever attended at Hamvention almost three
decades ago was Joe's Kit Building, but I'm sure he has updated the
presentation since then. This is in addition to the regular TNG on 10/31. *Note
to the Zoom masters: we would like to Zoom Joe's presentation.*

If anyone wants to or knows someone who might want to give a presentation
at a future TNG or if you have a topic that you would like to see, please
let me know.

Everyone is invited!!!

*License Exam Quiz #287*

I will apologize in advance for the circuitous route to the quiz topic this
week. I like to read historic documents around the date they made their
mark on American history. As it happens, I am reading George Washington’s
Farewell Address, which was not delivered but appeared in print on 19
September 1796. Technology then being fairly primitive by today’s
standards, print was the mass communication of the day. Printing of course
meant having to manually arrange individual letters in the press, manually
load single sheets of paper, etc. all to “mass produce” the newspaper. This
was Gutenberg’s technology of circa 1450 still the state of the art some
350 years later (and beyond)! Perhaps some of you have realized the
connection to radio here is Morse Code. The way we got the letter E to be a
single dit, and the letter T to be a dah, was by how many individual
letters it took to print newspapers. The most common letters at the
printing press were given the shortest combination of dits and dahs in
Morse code. There was no better way of counting which letters were most
frequent. In James Gleick’s book “The Information: A History, a Theory, a
Flood” it is stated the Morse Code was about 85% efficient, although they
did not say if they used as the denominator: modern American English; 1838
American English (when Morse invented the code); spoken vs. printed vs.
transmitted...in any case this has gone on long enough. To the quiz!


T1B07 Which of the following VHF/UHF band segments are limited to CW only?
A. 50.0 MHz to 50.1 MHz and 144.0 MHz to 144.1 MHz
B. 219 MHz to 220 MHz and 420.0 MHz to 420.1 MHz
C. 902.0 MHz to 902.1 MHz
D. All these choices are correct


G2C05 What is the best speed to use when answering a CQ in Morse code?
A. The fastest speed at which you are comfortable copying, but no slower
than the CQ
B. The fastest speed at which you are comfortable copying, but no faster
than the CQ
C. At the standard calling speed of 10 wpm
D. At the standard calling speed of 5 wpm


E8C05 What is the approximate bandwidth of a 13-WPM International Morse
Code transmission?
A. 13 Hz
B. 26 Hz
C. 52 Hz
D. 104 Hz



Answers:
T1B07 = A [FCC Part 97.305(a), (c)]
G2C05 = B
E8C05 = C
