I was playing around with a method for simulating ssb with Goldwave's mechanize feature, and I tuned it in here just to see if I could. http://freesound.org/people/kb7clx/sounds/275613/ If anyone has scanner recordings of taxicabs from the 90s that were using inverted audio on their fm transceivers, you could decode them this way.
Thanks for this sample. It really inspired this track for me. I have been meaning to re-record it and possibly use your cleaner versions so the words are not so garbled with the existing effects plus my additional effects.
