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

Amateur radio contesting is generally excluded from the WARC bands, which comprise the 30-meter, 17-meter, and 12-meter bands. These bands were established with a gentlemen's agreement that they would remain free from contest activity to provide a quiet refuge for casual operators during busy contest weekends. The 30-meter band (10.1 to 10.15 MHz) in particular is quite narrow and is exclusively restricted to CW and data operations in many regions. The rapid, high-volume exchanges of a contest would cause excessive congestion and disrupt normal communications there. The other bands listed (6 meters, 70 centimeters, and 33 centimeters) are VHF/UHF bands that actively host various domestic and international contests.
