Stop thinking shortterm. Yes *right now* both tv and radio stations
are sending-out duplicate signals : Analog and Digital. ----- But
that's only temporary. The TV stations will shut-down their analog
and just broadcast digital at approximately 1/10th the power of
analog. Likewise, AM will eventually end, and it will just be digital
at 1/100th the power.

And fairly soon after that HD will end and all will be consolidated in
the internet. You can hate progress, but it will still seek you out.
