radioguy39nj said:WTOP in Washington, DC, the Capital's long-time all-news outlet, was on 1500 AM with a drectional 50 kW signal. It could be received at night up the I-95 corridor, but not in many DC suburbs. Bonneville purchased the station, moved it to 103.5 FM and WTOP has had a dramatic increase in both ratings and ad revenue. WTOP is the highest billing station not in NY, Chicago or LA. I'd call that a successful migration from AM to FM!![]()
Ok, but you're saying the AM signal was poor in many DC suburbs. So it's not necessarily the AM to FM move that caused the ratings jump, it's that it moved from a bad signal to a good signal. Without knowing what would have happened if they moved to a better AM signal, we can't just assume the ratings jump is because more people like FM.
