Answer

The call letters for Bethesda-based Progressive Rock Station WHFS originally stood for what?

ANSWER:

B: High Fidelity Stereo

In 1961, WHFS began broadcasting from Bethesda with an easy-listening format. WHFS, at 102.3 on the FM dial, was the first multiplex stereo station in the Washington, D.C., area, transmitting from a 150-foot antenna above Triangle Towers in Bethesda. Not until 1968 did it begin broadcasting progressive music at night, starting with the show Electric Brew.
