FM Translators - Inproving Reception/Sound Quality

[kfbkfb]

AFAIK, it's still legal to use Dolby FM on (USA) FM broadcasts.

Listening while driving around my Metro Suburb, KCMO 710
suffers from interference (more at night), I usually listen on
103.7 (even at Home).

Maybe use Dolby FM or develop a new FM NR system modeled
after the old CBS CX (LP records and Laser Videodiscs) NR.

(Both Dolby FM and CX are said to be "listenable" even
without decoding)

A new FM specific NR system could extend the reach of
FM Translators without needing a transmitter power increase.

broadcasting in mono will also help it sound cleaner. especially on the flea powered translaters

As I understand it, Dolby FM is just another example where companding is involved. Whether it digital or analog companding in the effort to reduce or eliminate what could be a lot of white noise, the effect is annoying because white noise is so broad spectrum. For a while, Dolby used to license/produce a Studio To Transmitter Link. It was an early version of a true digital STL that utilized Dolby FM encoding/decoding. At the time it seemed to work well, until stations started using exclusively digital audio processing where audio artifacts were being created from dueling algorithms. That, and Dolby didn't sell enough of the STL's so production ended fairly soon.

Remember too..radio broadcasters are inherently cheap. I doubt one would want to pay Dolby license fees for a translator.
