Opinion PER CURIAM.

The only substantial issue is whether the Commission’s decision to refuse renewal to petitioner was a proper one. The Commission’s Order, United Television Co., Inc., 55 F.C.C.2d 416, 422, 423, 425 (1975), states that each of several independent reasons called for appellant’s disqualification, including breach of the Commission’s rules of technical operation. In our view, the long history of persistent violations of those rules was a sufficient reason for disqualification. The Commission’s decision is therefore affirmed on the basis of its discussion of this issue, and we reach no other question tendered by this appeal.
