Negotiators for NBC and the striking National Association of Broadcast Employees and Technicians concluded an all-day session yesterday and agreed to meet again today ...

But a spokesman for NBC expressed little optimism that a settlement was in the offing ...

Yesterday's negotiations were the first in the dispute since June 29 ...

For the past 22 days 2,800 NABET members, about 300 of them in Washington, have been out at NBC. That includes both radio and TV employes -- producers, writers, editors, camera operators, video and audio technicians, graphic artists and desk assistants ...

Yesterday in New York, negotiators met with a member of the Federal Mediation and Conciliation Service, who had called the sides together last week ...

A major obstacle to a settlement is new work rules that the union contends erode the job security of its members, specifically by allowing the hiring of up to 6 percent of the work force on a daily, as-needed basis ...

NABET claims that work should be done by regular full-time employes. NBC says it shouldn't have to carry on the payroll workers who aren't needed except for peak periods ...

In yesterday's talks, NABET showed a willingness to compromise with NBC on the work rules, but only if the network would consider enacting a four-day work week ...

The debut of two more shows on Fox Broadcasting's Saturday night lineup on Channel 5 drew a pretty fair audience response as the Fox schedule finished second in this market, behind NBC's comedy lineup, for the hours of 8 to 10 p.m. ...

"The New Adventures of Beans Baxter" averaged a 7.8 Nielsen rating and a 19 percent audience share, "Werewolf" went up to 10.7/22, while "Karen's Song" dipped to a 7.1/14 ...

Each rating point represents 15,800 TV homes in this market ...

The Fox shows averaged an 8.3/18, compared with a 12.6/26 for NBC's lineup on WRC, a slim 4.3/9 for ABC fare on WJLA and an anorexic 3.7/8 for CBS' "Space" on WUSA ...

And a rerun Friday night of the two-hour premiere of "Werewolf" on Five also turned out to be a howling success ...

Between 11 p.m. and 1 a.m., Fangs did an 8.3/24, beating the competition for those two hours on the three network affiliates here ...

On Sunday, however, the Fox lineup finished fourth, behind WUSA, WJLA and WRC, in that order ...

ABC Sports announced yesterday it will air a rematch between Alysheba, winner of the Kentucky Derby and the Preakness, and Belmont Stakes winner Bet Twice on Saturday, Aug. 1, from Monmouth Park, N.J. The Triple Crown contenders will meet in something called the Haskell Invitational ...

ABC says that with the addition of the Haskell, it is carrying 11 major thoroughbred racing events this year, the "most ever" by any network ...

Also in the News Tracy Scoggins, who played attorney Monica Colby in "The Colbys" last season, has replaced "Hunter's" Stepfanie Kramer as cohost, with Michael Young, of tonight's "Miss Teen USA 1987" telecast on CBS ...

Kramer reportedly is suffering from an inner-ear infection ...

Sharon Metcalf, who has been director of NBC corporate media relations in Washington for the past three years, is leaving the network at the end of the month ...

The move comes as NBC in New York reportedly downsizes the office. One sign: When Beth Manderfield, currently media coordinator, replaces Metcalf, she'll have the title of manager, corporate media, in Washington ...

After a month's vacation in Vermont, Metcalf will return to Washington, where she is considering several job options ...

Talk about your lively TV hearings!: C-SPAN will air the confirmation hearings this morning of Alan Greenspan to be chairman of the Federal Reserve Board before the Senate Banking Committee, Sen. William Proxmire presiding. Starts at 10 a.m. ...

Joan Lunden has signed a new one-year contract with ABC, on the eve of her departure from "Good Morning America" this week on a maternity leave that will keep the GMA co-anchor off the air well into the fall ...

Joining anchor Charles Gibson on GMA at the end of the week will be Kathleen Sullivan, who is currently negotiating a new contract herself ...

Kathleen's work schedule over the next couple of months ought to impress network negotiators, anyway ...

In addition to those very early morning calls five days a week for GMA up in New York Mondays through Fridays, she'll be in Washington on Friday afternoons and Saturdays to do her weekly "Health Show" and anchor the Saturday night network news ...

And a belated tip of the ole rabbit ears, tastefully festooned in pink, of course, to Betty Hudson, vice president, corporate and media relations, for NBC, and "Sunday Today" co-anchor Boyd Matson, proud parents of Erica Elizabeth Matson, who arrived at a New York hospital June 21 ...

(We warned you it was a teensy belated) ...

Then there's the happy news that in a private ceremony in Maryland Saturday, Channel 4 anchor Jim Vance and WRC program director Kathy McCampbell were married. It was the second marriage for both ...

Moving Right Along If it isn't one thing, it's another ...

"Ohara" (Pat Morita) will apparently be living in a houseboat when he returns to ABC this fall; Ed Flanders, Dr. Westphall on "St. Elsewhere," will depart the show after three episodes come September; and in the new "Star Trek" syndicated series, those awful Klingons are being replaced as the bad guys by the "Ferengi" ...

In response to a petition by its national news steering committee, the national board of the American Federation of Television & Radio Artists last week voted to finance and pay for the appointment of a senior staff executive -- with the title of assistant national executive secretary -- to coordinate all activities of news and other staff broadcasters in AFTRA ...

The news and staff broadcasters, including announcers and disc jockeys, comprise a total of only 5 percent of the 67,000-member AFTRA union but contribute about 25 percent of all AFTRA revenues with their dues payments ...

The news folks want AFTRA to pay more attention to their special needs ...

The union, which met in St. Louis, backed up the news committee's petition by voting in the convention to ensure that broadcasters' concerns were being taken care of ...

The convention also authorized discussions with the Writers Guild of America about long-range plans to merge its news writers into a single union of all news people, a step toward the eventual merger of all newsroom unions in broadcasting into one unit -- that could include NABET and the Directors Guild of America ...
