An update from Michele Muller, Director of Technology at KCSM:
Thank you for mentioning KCSM and JazzTV on your blog. We are still broadcasting JazzTV on digital TV channel 43-2. The scheduled programming runs from 8pm to 10pm nightly with a simulcast of KCSM FM with the JazzTV bulletin board the other 22 hours of the day. The monthly program guide received by KCSM members has a listing of the specific programs scheduled each night on JazzTV. I don't know why the website listings haven't been updated since September of 2004, but I will ask.
I know I have that program guide around here somewhere. Thanks Michele. See my previous story here.
