I have my opinion on the Houston Classical demise. The price paid for the signal was substantial. They moved classical to the new frequency and within about 3 months ran a pledge drive that missed the mark by, I think about 20%. Then they let the entire staff go, went Classical 24 and the FM signal put up for sale. The loss on the sale was $432,000.
Folks in public radio say you don't have successful pledge drives until about the 2 years in period. Since the classical programming simply moved from 88.7, I suppose that did not apply. I have seen commercial stations promote a frequency swap heavily and pay for it in the first ratings period. My point, Classical was never given the chance to succeed at 91.7. It seemed more like UofH wanted out of classical radio. In essence they turned it into a computer in a closet.
