Question E2C03:
From which of the following bands is amateur radio contesting generally excluded?  

Choices:  
A: 30 meters  
B: 6 meters  
C: 70 centimeters  
D: 33 centimeters    

Correct Answer is  A: 30 meters  

Correct answer: 30 meters

Why 30 meters is correct:
- The 30-meter band ($10.100$–$10.150$ MHz) is a WARC band. By IARU band plans and most contest sponsors’ rules, WARC bands are generally contest-free. This keeps 30 m available for non-contest operation and narrowband modes.
- In the U.S., 30 m also has additional restrictions: maximum $200$ W PEP and only CW/RTTY/data (no phone/image), reinforcing its non-contest character.

Why the other choices are incorrect:
- 6 meters (50 MHz): Actively used in VHF contests; no general contest exclusion.
- 70 centimeters (420–450 MHz): Commonly included in VHF/UHF contests.
- 33 centimeters (902–928 MHz): Also used in VHF/UHF contests; no general exclusion.

Useful rules of thumb:
- WARC bands (contest-free by convention): 30 m, 17 m, 12 m.
- 30 m (U.S. specifics): max $200$ W PEP; modes limited to CW and data (RTTY/data); no phone.
