I can't find where I read it, but I believe EMF got the license and transmitter equipment but not the studio or property. I could be wrong though, so take that with a grain of salt.
More than likely we will hear EMF at midnight fed through the WABB studio via web stream until someone can go out to the TX site and throw up a dish. Or it's possible someone from EMF came down and did that already since they were just in Jackson not too long ago.
EMF already has their rack on site I am guessing. When EMF launches a new station they ship in a preconfigured rack of equipment (ipump receiver, processing, remote control gear, automation etc.) basically it's plug and play for the most part.
Now since the sale has not been finalized by the FCC yet.. I am guessing main control will remain at the current studios for now until FCC approves the sale, the conversion to non commercial and the MSW to broadcast direct from the tower site.
