The callsign of 103.5 was changed from WSHQ to WQBJ on 7/1/94, so I would think that that was the date of simulcast. An interesting personal note on this. WSHQ was an adult contemporary. The company I worked for at the time had WSHQ on their Music on Hold on the telephone system. The telephone system was in the same room as the plant P.A. system which I took care of and had a key to the room. When 103.5 became WQBJ, the format included Howard Stern, so we ended up with him on the Music on Hold. Right away, management though someone with access to the room might have changed the station on the radio receiver, and I got questioned about it. When reality it was the format change. Needless to say, the radio got changed to another station immediately.
