The station in Norfolk runs America's Best Music from Westwood One around the clock. That format was Adult Standards some years ago, with prerecorded DJs most of the day. But in recent years, it is a mostly-Soft Oldies outlet with no DJs. Carpenters, Beatles, Neil Diamond, Dionne Warwick.
WJYI promotes itself more as an HD 2 subchannel on co-owned WNOR 98.7, than as an AM station on 1230 kHz. Unlike most Class C (formerly Class IV) AM stations, WJYI runs with 627 watts, not 1,000. Through most of its history, it had been 1,000 watts, so I don't know why it dropped the power. I suppose if the AM transmitter becomes too expensive to justify, Joy-FM 98.7 will exist as an HD and Internet station.
