Even better: If NRSC filter removal is not appealing to stations already participating in HD Radio, how about a deal with Ibiquity? Maybe Ibiquity would allow trade-ins of old equipment for new HD encoders! Let's see...in the back room we must have a C-Quam stereo encoder we don't need. Do you think they'll accept a license for an expanded band allocation? How about that Sony SQ quad encoder or this great FMX box? I'm sure Ibiquity would love to corner the market on used NRSC filters!
Just leave AM radio alone! Please turn off HD Radio IBOC, pull out the NRSC filters and let a grand old medium serve its public well! No other technology can achieve direct nationwide distribution using a ten dollar hand-held receiver. And, no, I don't want to listen to all my radio via the Internet quite yet. Get back to basics and let AM radio shine again. Have you ever heard two or three IBOC beehives phase together? Oh, my poor ears! Here comes the train! Let's stop it before it's completely out of control!
