KRQQ is an FM radio station in Tucson, Arizona, which is licensed to broadcast on the frequency of 93.7 MH. It has a power of 93,000 watts effective radiated power and is owned by iHeartMedia, Inc.. Its transmitter is on Tower Peak in the Tucson Mountains and the signal is mildly directional to avoid overlap KDKB in Phoenix, Arizona, under FCC rules that were in effect when the antenna was erected. Oddly enough, this is not vice versa.
