At least 1 "texoma station" DID try to buy it! Cumulus instead chose to turn in the license so they could immediately operate another FM in the DFW market instead of take a bonafide legitimate offer and keep it on the air with original programming. Their decision was even challenged but the FCC finally ruled they could not MAKE Cumulus retain ownership if they chose not to, which would have then made it possible to effect the sale.
They threw away a great deal of money by making that choice and put 104.1 off the air indefinitely and perhaps forever. It could possibly be available again in a future allocation, or it might be given to other stations for upgrades piece by piece etc. It just as likely could never resurface. Any station that used 104.1 for a translator would be forced off the frequency if it is ever re-allocated, which is why no one wants to put a translator or LPFM on that frequency.
As for KGAF, it is now a Class B and not eligible for a translator in the last filing window which was for Class C stations. If they open a filing window for Class B AM's, that can then be a possibility.
Also the signal upgrade on KGAF AM 1580 last year had nothing to with the AM revitalization effort on the part of the FCC. That was a simple minor change in license that we filed and were granted.
