NEW YORK (AP) _ Ex-President Richard Nixon will appear April 10 on the NBC-TV show ''Meet The Press'' for an hour-long interview - his first extended television appearance in eight years, the network said Wednesday.

''There are no set conditions for the interview,'' said NBC News Vice President Tim Russert, who had tried to get Nixon on the weekly program for three years.

Following the appearance on ''Meet The Press,'' Nixon will appear in a three-part interview with Bryant Gumbel on NBC's ''Today'' show. Nixon's last long television interview was in 1980 on the ABC-TV program ''20-20.''

The ''Meet The Press'' taping will be April 9 in Washington, said NBC spokesman Bill McAndrew. The program will be broadcast unedited, he said.

''Meet The Press'' moderator Chris Wallace will be joined by anchorman Tom Brokaw and commentator John Chancellor in quizzing Nixon, who resigned under threat of impeachment in August 1974.

Nixon will appear live on the April 11 ''Today'' show, with the following two days featuring taped highlights of his interview with Gumbel.
