i tracked down the emails of radio stations, sent them all a message.
out of 40-50 stations 10 responded with info on how to submit to them.
they gave me names of programs directors and address to send my demo.
this were all college or small stations, I didnt waist my time with commercial radio. Theres some nice people out there and its better to give them a call or email then to just send your cd to them. Plus they give you a referal wich might be the difference between the cd player and the trash can.
