You can forget 94.7. Back in the 60's, before the FCC came out with it's spacing requirements, the station on 94.7 WDSD Dover, as well as 94.7 in Bethesda, Md. and Newark New Jersey, along with to other stations I thing WDAC was one of them were allowed to upgrade to full power Class B. At the time WDSD (then WDOV-FM) was running 10,000 watts. Anyting over 3,000 was a Class B. All the stations had to agree, and they did so they are Grandfathered in. By the way Bethesda and Dover are closer togehter than currently allowed for Class A's. There are several stations in the Mid-Atlantic with this issue, example 100.3 in Washington, Media and New York. The same thing happened with TV in the early days, when WDEL-TV was on channel 7, and got interference from New York and Washington.
