I finished work on a C-QUAM (AM Stereo) transmitter, and now want to add  
something similar to RDS, but not sure how to go about it. I am aware of  
AMSS, but I like my wideband audio signal, and think that using the  
subsonic frequencies could work.

Basically, I want to send maybe a call-sign, genre, and maybe song info.  
For encoding I would porbably use UTF-16.

Any ideas?
