Some prefireworks skirmishes over the advertising parameters for the Fourth of July concert on the Mall -- the city's largest free entertainment event and the most prestigious promotional event undertaken by a local station -- seem to have died down with WAVA-FM's (105.1) rights firmly established.

WAVA won the exclusive contract over longtime cosponsor WRQX-FM (107.3) because the Love Foundation, the concert's sponsor, liked WAVA's audience, its business approach and its quick response to the foundation's requirements. "I was anxious to work out a deal before we went into production. WAVA was handling itself like businessmen in response to our needs," said Joseph Strauss, president of the foundation. "It further became apparent in the radio world it might be better for us to go with WAVA. Its audience isn't as targeted as some of the other bidders. Also, Q-107 waffled at the additional cost, and I couldn't wait."

A spokesman for Q-107 would not comment on the controversy over its advertisement for the concert, which WAVA and Strauss objected to and which was eventually pulled, or any other aspect of the bidding process.

Costs increased significantly this year for the local cosponsors, Strauss said, because of cleanup and protection fees to the National Park Service. When asked if the cosponsors were paying $40,000 each, he said the amount "was not far off," and WAVA would not confirm the price. Profits go to the Statue of Liberty restoration.

WAVA will originate live from the Mall beginning at 10 a.m., where its on-air people will be helping emcee and interviewing performers such as the Beach Boys, Katrina and the Waves, Joan Jett and the Blackhearts, the Four Tops, Christopher Cross, the Oak Ridge Boys and Mr. T. The station kicks off its Fourth mania with a remote from the Hyatt Regency on Capitol Hill July 3 with Charlie and Harrigan. Patriotic Notes
