I'm sorry to hear about what has happened to my former co-workers at Entercom Buffalo. But the idea that decent production that garners advertiser success must be done in house due to the nuances of a given local area are simply not the case anymore. While I am now a TV engineer on a full time basis, I also keep my hand in radio in my role as chief engineer for a standalone regional FM signal in my area on a part-time basis. This station serves many small rural cities and relies on small advertisers. The station used to employ an Operations Manager who doubled as a production director and provided most of the voices for the spots. When he left in 2012 the owner decided to try not replacing him and going with free lance voices instead. The results have been extremely positive. The different voices on the station tend to make the advertisers stand out from one another while the station owner doesn't have a full time salary to pay. In return the owner has put a good deal of money into the technical facilities to maintain the audio quality and reliability of the that aspect of his business. It's been a winner for him.
I always hate to see positions eliminated but in this case I understand his reasoning. Plus, when I see a hands on station owner who cares enough to buy all new digital studio gear, new and uncompressed music library, a transmitter and to purchase a $13k audio processor just to make sure his audio quality is as good as it can be it makes the engineer/audiophile in me appreciate them.
