Well, since CBS already has 6 stations in the market, they won't be able to purchase KRBE. That is, unless they sell off one of their AM's, which i don't think would happen.
I can picture KRBE going to Cox though, if Cumulus decides to really sell that too.
They (Cox) can sell off 106.9 and 107.5 and buy 104.1 and make it the home to the second incarenation of the point, but they should rename it to KRAP-FM if they do.
The AM let's see they own 610, and 650, some non profit, and/or religious could buy 106.9 after all it was once owned by Jimmy Swaggert. The same with 107.5 well not exactly it was 107.3 that was KJOJ before 106.9
Lakewood could acquire 106.9, to attract North Houston listeners. 107.5 having Lake Jackson COL could be spun off to Liberman, in return to cancel the 107.9 station.
