Until its cancellation in November 2013, his program The War Room with Quinn and Rose was aired on 12 stations across the U.S. and was also heard on XM Satellite Radio Channel 244 from 6 a.m. to 9 a.m. Eastern Time, Monday through Friday.

Quinn is best remembered in the Pittsburgh area as the vociferous nighttime host on KQV radio in the 1960s, during the station's peak as a Top 40 power.

[3] Quinn's final hour included a trivia game called "Stump The Audience", where the answers had been kept "in a sealed envelope on Funk and Wagnalls' doorstep since noon today".

In 1979 Quinn moved to the midday slot at WTAE radio, an adult contemporary station in Pittsburgh, under the aegis of General Manager Ted Atkins ("Captain Showbiz").

After a course of conduct wherein they implied that News Director Liz Randolph was promiscuous, she sued the station and Quinn and Banana for defamation and sexual harassment.

Quinn largely credits this lawsuit with inducing his conversion to political conservatism, saying "my formerly liberal eyes were opened to the agenda of the feminists, their friends and supporters in the media.

"[6] The Pittsburgh Post-Gazette reported that as of November 18, 2013, Quinn and his radio partner, Rose Somma Tennent, had been removed from the WPGB lineup.
