Stanford did some tests with Amplitude Compandored Sideband, but I don't think moto made any? I could be wrong. I know they hacked away at some motorolas to do this. An Amateur Radio BBS would get you more replies. try a search at the QSL.net -- Look for a Jim Eagleson.
do a search for his call ..... good luck Jim

Motorola never made ACSB, they were too busy pushing their 800 mhz trunking systems as the cure all for crowded channels. With the trunking systems using a propriatary protocol once into a market they would own it, since no one could build a radio other than Motorola to work on it. ( A footnote on that is in 1981 Motorola tried to force APCO to use their trunking protocol as the nationwide standard (APCO 11 or 12), fortunatly APCO told them to take a hike). In addition their market was mainly public safety, which is very leary of an unproven technology.
