Hi band vhf/low band vhf&fcc dumping big money involved.
 

Why is the 2-6 back in to play is the new equipment better than the old technology? Hf QSL 73.

I am certainly not (even close to being) an expert in low-VHF television broadcasting, but what I can say is that
- low-VHF signals can travel further than high-VHF and UHF signals of the same power;
- low-VHF signals, like high-VHF signals, are likely "safe" regarding spectrum repurposing (i.e. they aren't likely going to be seized for mobile broadband use);
- they could reduce confusion among viewers regarding virtual vs R.F. channel numbers since many stations have virtual channels that correspond to their old analogue low-VHF channels.

I think the "back in to play" is largely due to the opportunity to win large monetary payments during spectrum auctions and the ability of stations to have the same or larger coverage areas with less power, thereby saving money.

As for interference, I think this issue will largely be eliminated over time as TV broadcasting technology and error-correcting methodologies improve.

Hope this helps.

I think that is where white space come's in to play virtual and Rf.
ATSC keep the old technology box.like cm-70001.ATSC 03.
New OLD technologies ?
