Wait a few months, and you just might hear the "Morning Zooski" on WAVA-FM (105.1). Wednesday morning the station aired selections from the Tass Top 20, a Casey Kasemovich countdown of what's hot in the Soviet Union. But what started out as a summit goodwill gesture may mushroom into a full-fledged exchange.

Both ABC Radio Network and the Mutual Broadcasting System covered the hour-long show and fed it to about 3,000 member stations across the country, and a film crew from Tass, the Soviet news agency, was there to record the event for posterity and television broadcast back home. And, there's more. According to Alan Goodman, WAVA's general manager, Tass would like to export more Russian rock and may ask the musicians at home to record some of their songs in English; WAVA may take a trip to the Soviet Union next year for some (very) remote broadcasts; and Goodman hopes to meet with several Soviet broadcast officials about an internship exchange program.

"The feedback we've received on this has been awesome," Goodman said. "The potential for meaningful exchange here is tremendous."

But back to the actual show. Some might not consider the "Morning Zoo" team America's most diplomatic ambassadorial pair, but they performed admirably, sharing the mike with Michael Taratuta, deputy section head of North American service for Radio Moscow, and Andrew V. Ptashnikov, a Soviet radio and TV correspondent.

"It's one of the best things we've done," Goodman said. "You saw a serious side to Don and Mike that you don't see often. They are professionals. They recognized the importance of the thing."

A-WASH in New Ownership The sale of WASH-FM (97.1) for $29.25 million to Outlet Communications has finally been completed, giving Outlet, which already owns all-news WTOP-AM (1500), a formidable outlet in the nation's capital.

But a change in ownership does not signal a change in format for WASH, at least according to WTOP-WASH Vice President and General Manager Michael Douglass.

"There's been a lot of rumors about a change of format," Douglass said, "but we're not going to do so. They {WASH} were already doing the same thing we were doing at WMMJ {the FM station (102.3) that Outlet sold to Cathy Hughes for $7.5 million in October}. Both stations have 'adult contemporary' formats, but WASH's version was a locally programmed one, whereas WMMJ-FM used a syndicated format."

Douglass also said the stations would continue to operate as separate entities. "From a sales and programming point of view, we'll be separate." Outlet plans to move both stations sometime next year to studios currently under construction at McLean Gardens in the Tysons Corner area.

As to the almost inevitable layoffs that accompany such transactions, Douglass said that only "two, possibly three, people have been dislocated {let go}. But we had determined who would stay or go before we took over. We are going to evaluate all personnel, but at this point we plan to stay with the present staff. The need for change may surface, and you can never rule out the possibility of further change." Which is what managers are supposed to say.

Return to Normal News Just because the summit's over doesn't mean you get a break from hard news. WPFW-FM (89.3) is airing gavel-to-gavel coverage of the Senate Judiciary Committee confirmation hearings on the nomination of Judge Anthony M. Kennedy to the Supreme Court.

The coverage, which began yesterday at 9:30 a.m., is being anchored by George Wilson. Guests from the American Civil Liberties Union, the National Organization for Women and other interest groups both for and against the nomination will be interviewed, according to producer Askia Muhammad, "when the proceedings get a little dull." They may need a lot of guests.

Let the Jazz Trumpet Sound Jazz star Wynton Marsalis is in town this week, and WDCU-FM (90.1) has got him. The station, in an effort to introduce young adults to jazz, will present the trumpeter in three concerts: Thursday at Calvin Coolidge High School, next Monday at Lorton Reformatory and next Tuesday at the Oak Hill Youth Facility in Laurel. "We have pledged to expose at least 5,000 young people to this American musical art form this academic year," said WDCU General Manager Edith Smith. "America's youth must be made aware of the vivid and sumptuous riches that this music holds."
