Public media just sucks in the RGV. They don't have NPR anymore, PBS is on .2 and with this sale, Entravision is more likely expected to convert KMBH to a commercial station and drop PBS entirely. This would leave no public media station left in the area once it happens.
In fact, the nearest PBS and NPR member outlet to the RGV will be KEDT/TV-FM Corpus Christi (Laredo doesn't have its own PBS or NPR outlets either).
