The reason you hear WSB on 166.25 is due to the fact that many commerical stations use VHF frequencies to "cue" newsmen in the field and for linking of remote signals back to the station. Around here, during the evening news, the local TV stations tie up similar frequencies to "cue" their reporters as to when they are ready for their "live" reports from the field. They will simply transmit their "on-air" signal on their link frequency to the remote crew, who is monitoring it, waiting for their cue to report. If you listen around 950 mHz in many cities, you will hear STL's or Studio Transmitter Links which relay the broadcast from the station's studio location to their transmitter site, often miles away from the studio location. These 950 mHz signals are very directional, so you will have to be right in the path of the signal to hear it.
