Ya'll all over look HD radio.A few people I know have them.There's no bill.It's just like the new digital over the air TV stations.Buy an add on or buy a complete new radio.We have like 20 or 25 channels and I have my favorite local channels.You can also hold those channels for longer distance before there out of range.There's a button on the radios that retune and scan for new channels when get so far out but you don't loose your presets.They also still get standard channels that everyone with a antenee gets now.
Here is more info and there is a station guide on there.I found more channels than whats listed for my area.
