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

TNG – Thursday, August 22, 2024

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

No special presentation this week.

DARA/TNG is offering a two to three Saturday afternoon hands-on class on 3D modeling: September 21 and 28 (and October 5, if needed), 2:00pm at the clubhouse. Bring your computer and learn (by practicing) how to design your own 3D models. This focus is on utility prints, such as enclosures and antenna supports, not art style models. More details to come.

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!!!

de Steve, AE8AT

The Repeater Quiz was born at a Thursday Night Group back in 2018 in the later half of August. It was probably August 16th, with the first quiz going out in the Repeater that weekend. That means our little quiz has turned 6!!! To celebrate, in the tradition of Thursday Night Group’s Chaos Night, it seems fitting to allow random chance to determine this week’s questions. What do the fates have in store for us?

A. At the 12 volt battery chassis ground
B. At the antenna mount
C. To any metal part of the vehicle
D. Through the transceiver’s mounting bracket


G7C12 What is the frequency above which a low-pass filter’s output power is less than half the input power?
A. Notch frequency
B. Neper frequency
C. Cutoff frequency
D. Rolloff frequency


E9G01 Which of the following can be calculated using a Smith chart?
A. Impedance along transmission lines
B. Radiation resistance
C. Antenna radiation pattern
D. Radio propagation



Answers:
T4A11 = A

E9G01 = A
