Local polka disc jockey Frank Powaski will hold his fourth-annual all-night broadcasting marathon this Friday and Saturday, according to Pat Cloonan of the McKeesport Daily News.

Cloonan reports that Powaski, who will celebrate his 40th anniversary in radio this May, will kick off the 14-hour session at 5 p.m. Friday on WKFB (770). When that daytime-only station signs off at local sunset (7:30), Powaski will go across the hall to the North Versailles studios of its sister station, WKHB (620).

Powaski usually does three hours on Sunday afternoons on WKHB, but the marathon serves to kick off his summertime-only “Friday Night Polkas” show on WKFB.

Cloonan notes that Powaski is not asking for donations. “It’s not a fund-raiser,” Powaski said. “It’s just to promote polka music.”

Take that, Bob FM.
