LICENSE QUIZ #258

de Steve, AE8AT

On 12 December 1901, Guglielmo Marconi and George Kemp heard the letter "s" transmitted without wires across the Atlantic Ocean. While no amateur can claim a QSO for receiving a single letter, I guess that’s good enough for the professionals. This achievement led to Arthur Kennelly and Oliver Heaviside to suggest that a layer of ionized air exists in the upper atmosphere, which we now call the ionosphere. To commemorate the upcoming anniversary of 3 dits, the quiz topic is the ionosphere.

A. 6 and 10 meters
B. 23 centimeters
C. 70 centimeters and 1.25 meters
D. All these choices are correct

G3B05 How does the ionosphere affect radio waves with frequencies below the MUF and above the LUF?
A. They are refracted back to Earth
B. They pass through the ionosphere
C. They are amplified by interaction with the ionosphere

E3B07 What happens to linearly polarized radio waves that split into ordinary and extraordinary waves in the ionosphere?
A. They are bent toward the magnetic poles
B. They become depolarized
