In the past I have spent quite a bit of time as a technical volunteer at KTEH, San Jose's public television station. I haven't had much time to be involved with it in the past few years, but for nearly five years you could find me there for virtually every pledge drive and auction.
Over the years, I have been trained to work the positions of camera, shader, audio, still store, floor director, tech director, and even director. At one point, I was also one of the station trainers for the above positions.
Keep watching (and pledging), and you may see me. From time to time I'll even break down and help answer the phones. :)
