- Page 19 ③ ④ Effect of listening to shortwave programs at different times of the day What language programs can be received by shortwave radios? Shortwave signal propagation is subject to the influence of many factors, such as sunspot If in China, in shortwave radio programs, the Mandarin, activity, atmosphere and earth-ionosphere change.
- Page 20 ○ ⑩ How to test the effect of an Must the external antenna be very high and long? external antenna? In a general listening environment, In short, shortwave external antenna will get better effect if it is high and long. But, higher and longer antenna doesn’t turn the radio to a relatively weak imply better effect.
- Page 21 ○ ○ How to reduce the interference of Shortwave radio Shortwave is transmitted mainly relying on the reflection Shorten the lever, change the direction of the and refraction between ionosphere and the ground, antenna, change the listening position, and keep regardless of day and night.
- Page 22 ○ ○ Why more radio stations received at night than that of the daytime? What factor will affect broadcasting reception effect? Medium wave propagation mainly relies on the ground wave. Only a small amount of medium wave is transmitted The reception environment is the main factor that affects by relying on sky wave.
