In an order effective November 15, 1963, the Federal Communications Commission has announced that broadcasting stations on the band 608–614 Mc (TV channel 37) will not be authorized anywhere in the United States before January 1, 1974. The order is intended to provide protection from interference by broadcasting stations for radio‐astronomy receivers tuned to this waveband. After ten years the question will be reconsidered and it will then be decided whether to continue protection or to begin licensing stations on channel 37.
