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

Explicación

Contests are kept off 30 meters, along with the other narrow bands gained at the 1979 conference. The band is only 50 kHz wide, is shared on a secondary basis with fixed-service stations, and carries no phone at all, so contest activity there is barred by band plan and by contest rules rather than by the FCC. Contests are commonplace on 6 meters, 70 centimeters and 33 centimeters.
