I agree.
On AM, HD Radio is a disaster.
On FM, expensive, complex, proprietary HD radio is unnecessary. You can get better performance, extra programming channels, digital performance, and better compatibility without using adjacent channels.
See FMeXtra, the truly In Band On Channel FM digital transmission system that got final FCC approval
before HD radio:
www.dreinc.comSince we are into repeating ourselves here:
"On AM, HD Radio is a disaster."Am radio is a disaster. Ancient demos, declining listener base, it's remaining viable format slowly migrating to FM. Once-great AM facilities now in the hands of churches and other hucksters.
AM iboc may be grasping at straws but the stations that
can implement it are atleast trying to survive.
FM Extra: Nice idea I like the concept of non-proprietary software, however it kills the use of subcarriers and if you want full digital bandwidth (which is still half the iboc maximum) you have to kill the baseband stereo. Mono FM, is that your idea of progress?
Stations broadcasting in FM Extra - USA= 4
" " FM Iboc - USA = 1200+ and counting.
Receivers?
