Andrew Young is planning to put his show on the air.

The U.S. ambassador to the United Nations has authorized a private television producer in New York to negotiate for a weekly TV talk show.

The producer, independent film-maker David Garth, said yesterday that prospects appear favorable for launching Young's program "at the end of September" through groups of independent commercial stations or no public television. He said specific negotiations are "at a very preliminary stage," but added. "I don't have any doubt about it going."

The news that Young, whose off-the-cuff comments have produced a series of controversies, was planning a debut as a television performer came as a surprise to officials at the White House and the State Department, including Secretary of State Cyrus R. Vance.

White House press secretary Jody Powell said. "I handn't beard about that, but it might not be a bad idea. Andy would probably go over pretty good in that situation."

Powell said Young's "problems" with the press and public - including a recent flap over "racism" resulting from a Playboy interview - "have been when people have not heard or read everything he said. It may be better for him just to have people hear what he said, rather than reading a headline."

Hodding Carter III, the State Department: spokesman, said that "if it works out to Andy's satisfaction. I'm sure it would be useful. We try to get everybody to participate in any kind of media exposure he or she can get."

Efforts to reach Young in Geneva, where he is attending a U.N. conference, were unsuccessful.

Garth, who is well-known in political circles for his campaign spots and has a campaign strategist for such candidates as former New York City Mayor John V. Lindsay, said he and his partner, Arnold Michaelis, had approached Young with the idea last March.

He said that he and Michaelis had produced a similar program for the late Adlai E. Stevenson when he was U.S. ambassador to the United Nations in the early 1960s. And ABC sopkesman said that network had carried the Adlai Stevenson Reports program on alternate Sundays from October, 1961, to May, 1963.

Garth and Tom Offenburger, Young's press secretary, said that the format calls for Young to discuss foreign policy issues with his guest of the week, who may be another nation's U.N. ambassador, an official of the Carter administration or a member Congress.

Industry sources said Garth had promised to produce such guests as Vance and the President's national security affairs adviser, Zbigneiw Brzezinski.

Offenburger said that when Young cannot host the program himself, one of the other five ambassadorial-rank members of the U.S. mission to the United Nations would sit in for him.

Both Garth and Offenburger said Young would receive no payment for his part in the program. Garth, declining to specify the offering price for the show, said. "We hope to make some profit off it after meeting the production costs."

Garth also siad he has approached various companies for possible sponsorship of the program, adding that if there were commercial sponsorship it sould be "of an institutional nature, very low key."
