- We can always use net controlers, which means that you can try your hand at running a LEARA net! Give it a try, it's not that hard. Learn the voices and call signs of your fellow radio members. We presently have 7 active net controlers to bring you the net each week. Why not join up and give us a hand.
You can even do a part time shift - say 4 times a year! Give it a try!

The county EMA does not expect any emergencies, however they would like to have eyes at these locations to monitor the situation. This will be condidered as an emergency activation.

Past Trivia / Discussion Questions
- 01/18/24 Question: When was the first voice moon radio bounce?
Choices: A: 1928, B: 1938, C: 1946, D: 1954
ANSWER C: 1954
On July 24, 1954, the Naval Research Laboratory (NRL) at Stump Neck, Maryland (now the Naval Surface Warfare Center in Indian Head, Maryland) sent and received the first human voice transmission to be bounced back to Earth from the Moon.
Moon bounce, also known as Earth-Moon-Earth (EME) communication, is a technique that sends radio wave transmissions from Earth to the Moon. The transmission is then reflected, or bounced, off the surface of the Moon and captured by an Earth-based receiver. The technology held promise for secure communications with Navy ships.
By January 1956, the U.S. Navy could transmit teletype signals to and from Stump Neck and Wahiawa on the island of Oahu, Hawaii. By January 1960, the Navy’s Communication Moon Relay System began transmitting two-way radio communications. - 1/25/24 Question: What is the maximum propagation distance of 2-meter signals to stations lying beyond the horizon?
A: 115 miles / 185 km
B: 25 miles / 40 km
C: Well over 500 miles
D: 10 miles / 16 km
Answer: Well over 500 miles
(Meteor Scatter can propagate signals well over 500 miles on the two-meter band, as can tropospheric and even ionospheric conditions.)
Discussion: What is the farthest 2M distance you worked, or heard? - 2/01/24 Question: A BC 454 radio was a...
a) Command Set, b) Hallicrafters, c) Air Line Radio, d) Broadcast Carrier Set.
Answer: a- Command Set.
The BC 454 receiver was used in aircraft during WW 2 and covered 3-6 Mhz. After the war they were often converted for amateur radio use.

A) 12.5 hours, B) 17.5 hours, C) 22.5 hours, D) 27.5 hours, E) None of the above, it still took 5 hours
Answer: b) 17.5 hours - 2/15/24 Question: When was the last total solar eclipse that was visible from Cleveland?
A. 1796, B. 1806, C. 1817, D. 1822
Answer: B. 1806

A. worked alongside Samuel Morse
B. First astronaut to take a ham radio into space.
C. Worked on the original ARRL Handbook.
Answer is B - 2/29/24 Queston: Which power change below represents the FEWEST dB of difference?
A: 1 watt to 125 watts (21 dB)
B: 1 milliwatt to 3 watts (33 dB)
C: 125 watts to 2 kilowatts (12 dB)
D: 1 milliwatt to 1 watt (30 dB)
Answer: 125 watts to 2 kilowatts
How it works
Power gain (dB) = 10×log (RF output power / RF input power). Used in RF.
Power gain is defined as the ratio of the output power to the input power in dB.
Assume that the input power is 10 mW (+10 dBm) and the output power is 1 W (1000 mW, +30 dBm).
The ratio will be 1000/10 = 100, and the power gain will be 10×log 100 = 20 dB.
Reference power P0 = 1 Watt.
More info available at: https://sengpielaudio.com/calculatorVoltagePower.htm#:~:text=Power%20gain%20(dB)%20%3D%2010,power%20%2F%20RF%20input%20power
Simple way to use doubling to determine change in dB. Every double of power is 3dBChange 125W - 2000W
power 125W 250W 500W 1000W 2000W dB 0dB 3dB 6dB 9dB 12dB - 3/07/24 Question: Before WW II, how many US States were in W0 (zero) land?
a) 6, b) 8, c) 4, d) 0 - none
Answer: d)None
The tenth call district was implemented in 1947, during the post WW II boom in amateur radio. The creation of this new district was basically to equalize ham populations among the districts. - 3/14/24:
- 3/21/24: When were the first call signs beginning with “K” issued in the Continental United States?
A. 1939, B. 1942, C. 1945, D. 1947
Answer: D. 1947

Trivia Question Etiquette
- The Trivia Question is supposed to be a fun and learning experience for everyone checking in. Most of the time the answer is a multiple guess, and for many literally a guess. It makes the people sit and ponder the possible answers. If you don't know the answer, you may say so and acknowlege that you are taking a guess, and then give your answer. If you KNOW the correct answer, please just give give the letter or text of your choice only. Don't spoil the question for others by giving a complete dissertation on the principals, theories and biographies of the author or scientist. Giving that information early in the net spoils the fun for the people who have yet to play. Factoids and anecdotal information regarding history or even personal experience relating to the question is a most welcome additive to the discussion AFTER the answer has been given. Let the Net Control KNOW you have additional info for the end of the net.
Thanks for checking in and enjoy learning new facts, or basking in the knowlege that you have.
