Most ATSC STBs have signal meters that are used for antenna tuning. In my area, all but PBS transmits at 10% of their analog ERP, PBS transmits at 20% of their analog ERP. And yes, the whole reason for this switch is so the FCC can auction off the unused $pectrum. But, even though our government is money hungry, we all can benefit from digital TV if the transmitter power is high enough. Clear picture, EPG, show title, description, and sub channels. All of the modern digital features we got used to with satellite TV. But, TV DXing will be gone, unfortunately.
