Question
From which of the following bands is amateur radio contesting generally excluded?
Answer Options
- A) 30 meters
- B) 6 meters
- C) 70 centimeters
- D) 33 centimeters
Correct Answer: A
Explanation
Contesting, or competitive operating, is a popular activity in amateur radio, but certain bands are internationally reserved or discouraged for routine contact, casual DXing, or emergency use. These bands have a specific purpose and are generally protected from the high-intensity, repetitive contacts common in contests.
Amateur radio contesting is generally excluded from the 30-meter band (10.100 - 10.150 MHz). This band is internationally reserved primarily for digital communications and weak-signal terrestrial contact and is recognized as a non-contesting band by the FCC and international amateur organizations to minimize QRM (man-made interference) and maximize the utility of the band for secondary uses.
