In a filing to the FCC, the Association for Public Television Stations is asking that pubTV stations wishing to do so be allowed to transition to digital this month or next. Numerous stations want to switch to digital as soon as possible for technical and financial reasons. But the commission last week proposed no more analog shutdowns until April 16. Also in an FCC filing, Wisconsin Public TV asked that it be permitted to transition on April 5. The FCC has proposed various deadlines and requirements for the new June 12 deadline.
