KQLC in Sealy has a Spanish language religious format, but would be unusual to hear it that far to the east. I only get extremely weak and spotty reception of it in Cy-Fair.
Radio-locator lists LPFM KGBV in Hardin (near Dayton) on 90.7, but unknown format. I was unaware of it until now, as it is not listed on the lpfmdatabase website. Extremely unlikely.
The English programming could be from KVRT in Victoria, which is Public Radio. Can often be heard in Houston when tropo kicks up.
