Assuming you know this and didn't mean otherwise, but just to make sure: the db on here is not the "FCC db", it is the RadioReference database which is manually entered based on submitted info from users (such as yourself).
Vilonia (and no agency in Faulkner Co) is not licensed for 155.115, per a search of the FCC ULS.
A few other cities in Arkansas are licensed for it:
-Van Buren
-Mountain View
-Arkadelphia
-Trumann
-Wheatley
-as well as "Holiday Island Suburban Improvement District"
155.115 is kind of close to 155.1225, though.
The FCC is sometimes a little slow at getting things posted and listening is definitely an important way of determining what a frequency actually is so it could be the FCC hasn't caught up with licenses. (?)
milf, what do you think?
