The Corporation for Public Broadcasting board yesterday named Ron Hull to succeed Lewis Freedman as head of the programming fund . . .

The board also voted to add $2 million to the current $19 million in the fund for next year . . .

Hull is program manager for the Nebraska educational television network, assistant general manager for programs at KVON, the University of Nebraska station at Lincoln . . . and teaches TV at Nebraska . . .

The board also reelected Sharon Percy Rockefeller as chairman, but New York media consultant Sonia Landau replaced civil rights attorney Jose Rivera as vice-chairman . . .

Former president Jimmy Carter was put on hold for "three or four minutes" by somebody in the ABC newsroom in Washington yesterday morning and he didn't like it . . .

Carter, calling from Plains, Ga., had been trying to contact his former security adviser, Zbigniew Brzezinski, before the latter went on "Good Morning America" to comment on President Reagan's plan for the Mideast . . .

After they finished chatting, news anchor Steve Bell got on the phone and asked Carter if he'd be interested in doing a phone interview on the subject later in the broadcast . . .

Carter told Bell to call him back . . . but after his interviews with Brzezinski and Secretary of State George P. Shultz, Bell went back to the phone and discovered the 39th president had been on hold for a while . . .

Carter, who finally talked on the program for about seven minutes, told Bell when he first picked up the phone, "I don't mind talking to you, but I don't have time to be put on hold" . . .

Bell said nobody in the newsroom could be found later who would admit putting the former president on hold . . .

The CBS Inc. board of directors meets in New York on Wednesday and yes, CBS chairman William S. Paley will be there . . .

Sure to be on the agenda, according to CBS sources: those reports of Paley's retirement . . .

Channel 26 said yesterday that its official final tabulation for the 12-day fund-raiser that ended Wednesday night . . . shows that the station raised a total of $301,382 from 7,577 new memberships . . .

A figure flashed on the scoreboard at the completion of the White House concert program that night had showed $303,000-plus . . .

Biggest money-raiser: the Saturday night performance of "La Boheme" with Signor Pavarotti . . . worth a total of $41,406 . . .

Second best for WETA: Wednesday night's reprise of the White House concerts, which yielded $34,305 . . .

Incidentally, WETA interrupted that 2 1/2-hour telecast of "La Boheme" a total of 40 minutes for money-raising pleas . . .

We mention that because up in Philadelphia Lee Winfrey, a respected TV columnist for The Inquirer . . . has created a stir by complaining that WHYY there took 50 minutes during its telecast of "La Boheme" to make sales pitches . . .

Not so, says WHYY vice president and general manager Jim Karayn . . . "We took only 31 minutes" . . .

Karayn also pointed out that the regular PBS feed of the opera (which WHYY did not use) included three 12-minute fund-raising breaks . . .

Karayn said yesterday that he'd heard that up at WGBH in Boston, that station interrupted "La Boheme" with one 14-minute fund break plus a 13-minute and three 12-minute pauses . . . which, a hasty run through the abacus reveals, would add up to an hour and three minutes . . .

(WGBH yesterday said they took "only" 49 1/2 minutes and raised $41,451) . . .

Karayn says WHYY's 31 minutes yielded around $25,000 that night .
