To qualify as a class B station spe- @lal requirements are necessary. Stu- dio arrangements to eliminate rever- berations must ba made: equipment Must be such as to prevent harmon- {es; a special antenna must be erect- @ %0 as fo prevent swinging, and re- Hable equipment, with spare parts, must be used. These stations are aranted power between 500 and 1,000 watts, and in a few casex as high as 1,500 or 2,000 watts. Thev operate on Wave lengths hetween 280 metars and | 345 meters.
