Ace and TJ were primarily carried by other iHeart stations when they were first carried out of Charlotte, but now they seem to have a deal with SummitMedia to carry them in every market they can, usually on a AC/Hot AC and their three “Awesome” branded classic hits station.
Down here in Greenville/Spartanburg they were first picked up by WMYI/My 102.5 about 10 years ago, then on alternative X98.5 (a bad move) after that station became adult hits. A couple of years ago, they moved up to sister station classic hits Awesome 99.5, which makes much more sense.
I wonder how big their following is here considering WNKS and WHQC both covered the market fairly well depending on the area, and they’ve been on locally for over a decade now although the two translators don’t cover the Spartanburg or Anderson portions of the market unless you listen to the originating HD signals on 107.3.
