Your post indicates you think that Digital TV will save space?? HDTV uses 6Mhz(all of it) to transmit and analog actually only uses approximately 4.75Mhz (a savings in EM space actually). The FCC allocates 6Mhz per station whether its digital or analog so I doubt that it will really matter. The savings comes in with the switchover due to many station broadcasting in only one format instead of the two different formats (one in analog and on in HD) the FCC currently allows them to transmit in both. Food for thought.....

Sorry I had the distance between main carrier and sound carrier stuck in my head but isn't it actually 5.75 for analog?
