If the sale happens can KADN move its subchannels to KLFY's 1718 foot monster and sell the channel 10 assets and their lil stick south of Church Point
no they cant move towers. If they keep KADN (again hypothetical) then they either sell KLFY as is (tower, license, programming) to someone else or they can buy the assets of KLFY but they would have to move the programming to the tower of KADN.
They can't pick and choose what they want. If they do the asset route its everything BUT the license and transmitter for that station. Plus the antenna is tuned to transmit on RF10 whereas KADN is on RF15
