If I remember right,when the dtv switch occurred, vhf was to go 100% off the air. I thought I heard this was so they could improve communication during emergencies. Since when 911 happen they had so many communication problems. But really that is going to happen when you have so many people trying to use cell phones. Now it seems Vhf high band 7-13 is making a come back. Is this true. Also I've noticed the max power allocated to tv signals is waaaay less with digital now. I was hoping before the switch it would be so if you where getting the analog signal you will get the digital signal, but that seems to be far from true.
