You don't need clear QAM to pick up the channels that a converter will tune. The entire point is to provide OTA support to those who have no other means. At this point, clear QAM brings only HD local support which is outside the scope of a lifeline SDTV project. In many cases, unless you subscribe to basic cable ($40-60/month), the clear QAM channels are tanked out.My point is - these boxes sure would be more useful if they did have Clear QAM, so that I could also use cable as an alternative to an antenna.
The idea is not to build a dependency on these converters. Further, it is not designed to add life to your outdated television (or one that you bought at clearance for a "real sweet deal"). If you want to keep using it, just buy a box that does what you want. I'm guessing that there will be a market for outboard digital tuners like there is now that just aren't coupon compliant.
