There's really nothing new on that frequency, except for a CP for an EMF translator in Millington. I hadn't heard about that coming on yet, but, here in Germantown, I may not hear it.
I tend to get Water Valley most of the time, and occasionally, Selmer. So, I can't say what you heard without some format information. But here's the list of what's out there:
KBOA 105.5 FM 84.3 mi. 354° Piggott, AR Nostalgia
KWAK 105.5 FM 95.8 mi. 241° Stuttgart, AR Oldies
WAKQ 105.5 FM 121.8 mi. 048° Paris, TN Top-40
WNLA 105.5 FM 119.7 mi. 199° Indianola, MS Adult Contemporary
WTNM 105.5 FM 63.9 mi. 168° Water Valley, MS Talk
WVNA 105.5 FM 131.7 mi. 103° Muscle Shoals, AL Classic Rock
WXOQ 105.5 FM 73.7 mi. 084° Selmer, TN Country
Hope this helps.
