Look. all I was trying to say is, that when a classical piece goes to a softer or "quieter" section, then I really prefer --not-- to hear any FM static, which happens when listening to WRR in Dallas . . .
Yes, the defective iBiquity HD digital radio system adds digital noise that sounds similar to fm noise to the analog stereo signal. That is the noise that "goes away" when an HD radio switches to digital. What they don't tell you is that the extra digital noise is an artifact of adding the problematic HD digital carriers to the analog stereo signal.
This is extra HD noise that a non-HD station does not have.
You can plainly hear the digital noise by taking an analog FM radio (even mono) and tuning just above or below the HD FM station. It sounds similar to FM noise, but with a slightly different character.
jim 8230 is probably correct when he said his analog FM station has no such noise problems.
For WRR-FM to get rid of the annoying digital noise, all they have to do is switch off the noise generating HD signal. Then they will have pristine, full fidelity, long range, analog stereo FM again.
HD radio claims to fix what was not broken, until HD radio came along to create added digital interference.
