What is transequatorial propagation?

1. Propagation between two mid-latitude points at approximately the same distance north and south of the magnetic equator
2. Propagation between points located on the magnetic equator
3. Propagation between a point on the equator and its antipodal point
4. Propagation between points at the same latitude

E3B02:

What is the approximate maximum range for signals using transequatorial propagation?

1. 1000 miles
2. 2500 miles
3. 5000 miles
4. 7500 miles

E3B03:

What is the best time of day for transequatorial propagation?

1. Morning
2. Noon
3. Afternoon or early evening
4. Late at night

E3B04:

What is meant by the terms "extraordinary" and "ordinary" waves?

1. Extraordinary waves describe rare long-skip propagation compared to ordinary waves, which travel shorter distances
2. Independent waves created in the ionosphere that are elliptically polarized
3. Long-path and short-path waves
4. Refracted rays and reflected waves

E3B05:

Which amateur bands typically support long-path propagation?

1. Only 160 meters to 40 meters
2. Only 30 meters to 10 meters
3. 160 meters to 10 meters
4. 6 meters to 2 meters

E3B06:

Which of the following amateur bands most frequently provides long-path propagation?

1. 80 meters
2. 20 meters
3. 10 meters
4. 6 meters

E3B07:

What happens to linearly polarized radio waves that split into ordinary and extraordinary waves in the ionosphere?

1. They are bent toward the magnetic poles
2. They become depolarized
3. They become elliptically polarized
4. They become phase locked

E3B08:

What is the term for the long path opening that exists between two points on the Earth which are simultaneously near sunrise and sunset?

1. Transequatorial
2. Sporadic E
3. Long-path
4. Grayline

E3B09:

At what time of year is sporadic E propagation most likely to occur?

1. Around the solstices, especially the summer solstice
2. Around the solstices, especially the winter solstice
3. Around the equinoxes, especially the spring equinox
4. Around the equinoxes, especially the fall equinox

E3B10:

Why is chordal hop propagation desirable?

1. The signal experiences less loss compared to multi-hop using Earth as a reflector
2. The MUF for chordal hop propagation is much lower than for normal skip propagation
3. Atmospheric noise is lower in the direction of chordal hop propagation
4. Signals travel faster along ionospheric chords

E3B11:

At what time of day can sporadic E propagation occur?

1. Only around sunset
2. Only around sunset and sunrise
3. Only in hours of darkness
4. Any time

E3B12:

What is the primary characteristic of chordal hop propagation?

1. Propagation away from the great circle bearing between stations
2. Successive ionospheric refractions without an intermediate reflection from the ground
3. Propagation across the geomagnetic equator
4. Signals reflected back toward the transmitting station
