Doubt if a specific answer is forthcoming on that one! But shortage may not be the right word. Congress clearly thinks there is extra capacity available. Dish is not about to reveal this kind of information. The recently activated Echostar 14 has added spotbeam capacity. Some of that will go to meeting the earlier FCC formula that requires 30 percent of markets in HD (all stations in a market, not just noncoms) by early next year. That's an increase of 15% over the benchmark they reached early this year (by adding very small markets). To reach 50 percent of market for HD noncoms by the end of this year, means an additional 20 percent beyond the above requirement, or roughly 40 additional PBS locals in HD, assuming Dish can continue to target smaller markets with just one noncommercial station each. Another spotbeam satellite is due for launch next year. PBS viewers in large markets will no doubt have to wait it out to the bitter end! Another year and a half if Dish's FCC lawsuit fails.
