The former HBC markets had rights of prior usage. EMF has made agreements there. Houston is one of those.
So it would appear that EMF could launch K-Love in the Houston market should it choose to do so. 92.1 would be the perfect place should Urban One decide to dump its ratings turkey. However EMF may keep K-Love out of the market in deference to similarly formatted KSBJ. The closest K-Love stations are a pair of translators in Beaumont-Port Arthur.
