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?
