Equity was based in Arkansas and ran pretty much all their stations out of Little Rock (that is why most of them were on free to air. The signals were so weak that the only way cable companies got the signal was from the satellite)
Luken is in Chattanooga
They both probably sued each other. When Equity and Luken couldnt reach an agreement on RTN Equity pulled RTN and put up a slate for a day (known as the red screen of death) before Equity did the "wheel of affiliates" where they had some public domain movies that were shown before they switched to TuffTV or ThisTV (this was early 09 and they ended up going bankrupt before the DTV transition that year. They sold off most of the stations)
Ironically, Soul of the South bought the equipment that Equity had in Little Rock to run their stations.
