OK... I still don't get this. Improve range and multipath on an FM station with an Optimod? What am I missing here?
And, while we're at it, here's this one. https://www.radioworld.com/tech-and-gear/digital-radio/what-about-audio-processing-for-hd-radio

Hey Dood,
I am also kind of lost with the information in the links.
Unless I am missing something very fundamental ( which is a distinct possibility), as I understand it a signal is limited to the old rules: path/ terrain, antenna height/ power, blah, blah.
As I have experienced, an analog signal goes through a gradual degradation from good to fair, then noisy , then gone.
Digital transmissions go from very good to maybe a brief chopped up good, then very rapidly vanish .
I am not sure how someone has suddenly developed some magical new physics that defy, what I thought, were the basic rules of a station’s range- be it analog or digital.
So by messing around with bit rates, compression and what ever else, you are suddenly going to double the range.
Maybe I am really dumb about digital
“ manipulation “ ( possible) .But digital seems to be the INFERIOR Dx mode, no matter how much you shuffle it.
I maintain an open mind, but so far,I’m not getting this either.

Stereo, and in particular, the use of "stereo wide" settings in an audio processor can affect multipath. So it's possible, I guess, that it can be improved.
Regarding being able to now hear a station at almost twice the distance after installing a new processor is nonsense.

I think I would agree.
It almost sounds like a snake oil sales pitch to me.
