I think it's a push by both Entercom and iHeart to get their respective LGBT services in all the big markets, especially during June, Pride Month. iHeart's Pride Radio is all music from what I understand. I'm not even sure it has DJs, just liners?
Channel Q has weekday talk shows. It runs dance music nights, weekends and whenever a talk show has gone off the air. (Channel Q used to have a two-woman show in middays but apparently that's gone, replaced at least for now with music.) Channel Q is also heard on a Class A FM station in Palm Springs, a resort city that has many LGBT visitors. It's also on an FM translator in Seattle and on an AM station in San Francisco. Meanwhile iHeart's Pride Radio is only on HD stations. And of course, both are on their respective on-line platforms, iHeartRadio and Radio.com.
