In Durham, North Carolina, 99.1 FM these days is Morrisville-licensed W256AX, a translator of Franklinton-licensed WRTP 88.5 FM (contemporary Christian-formatted His Radio). There was once a WRTP translator in Creedmoor on 99.1, W256AH, but I think that is silent now since a city of license move and signal improvements to WRTP made it redundant. If we hear anything else here on 99.1, it's usually either Whiteville, NC hip hop station WZFX Foxy 99 or Roanoke, VA AC WSLQ Q-99.
Other 99.1's I've logged include:
WVOD, Manteo, NC
KRYS, Corpus Christi, TX
KODA, Houston, TX
KEEZ, Mankato, MN
WIKB, Iron River, MI
WKFX, Rice Lake, WI
KXKC, New Iberia, LA
