This is an old thread and and I didn't scroll through all of it, so I'm. sorry if I'm repeating anything. Nomination for worst station of all time WERM, Wapakoneta, Ohio. Located between Wapakoneta and St Marys, this FM was family operated----the epitome of mom and pop. The audio was bad from beginning to end, distorted and off LPs. It was Beautiful Music by day, then the kids took over for the 6 to 10 club, which was sort of top 40. They did carry Wolfman Jack's show for the US Air Force, as well as some of the others geared to other formats, including Al Gee's soul show. Eventually the station was left to the sons, who turned it into.....a hobby with screeching rock, and vinyl records worn beyond ability to play. I worked at this station when the next ownership took over. It was a technical mess.....safety interlock disabled on the transmitter, other disasters. The station became A/C WAXC, and eventually top 40 WZOQ. I believe it's sports now.
Also, from way back, WPGW, a daytime on 1440 in Portland, IN. Owned by founder Glenn West and his wife, the two ran the station until it was sold around 1974. An FM CP was built out after that. Under the Wests, the format was album sides and 3 of the 4 ABC networks. You'd often hear Mrs. West talking between the Contemporary and Information feeds in a sing-songy voice "your ABC Network News Station, WPGW in Portland, Indiana.".
More recently, I'm going to nominate WSEV (AM930/now with translator at 104.1). (WSEV-FM, "MIXX 105.5 is under separate ownership). For many years, AM 930 was the voice of tourism in Sevier County....and, unlike others who have contributed to this board, I never had a problem with that, including the constant repetition. It wasn't there to be your go-to listen at work station; it was supposed to be tuned in when the visitor saw the billboard on I-40, and the station would provide enough enticement to get one to stop at the designated welcome center, and hopefully, sign up for a time share tour. Nothing wrong with that EXCEPT when the recording got so far out of date that it was talking about closed shows and attractions. The problem was, no one, apparently even the FCC, knew where the control point was. Once the decision was made to suspend operations, somehow the transmitter kicked back on and ran dead air for a couple of months. Bringing things to present day, the station was purchased by Bristol Broadcasting which ran a 3 song rotation for awhile, built out a translator, loaded music into the automation and forgot about it. It sounds like it's being fed by a cheap internet feed, or a cassette that's sat in a hot car all summer.
