RadioTXT is the only in-studio Text Messaging System that complements all the elements of your broadcast from one simple, easy to use interface. In addition to the standard WebTXT functionality of Competitions/Sweepstakes, Votes and Comments RadioTXT includes:  

Track Requests
Listeners are able to Text in while a track is playing to find out what the name of the track, band and album is. If there is a ringtone or graphic available for the track, listeners can order it by SMS and have it delivered to their phone immediately.

Dedications
Tired of going through endless telephone calls to see what tracks your listeners really want to dedicate to their friends? RadioTXT does it all for you with a comprehensive system that lists all the dedications in order.
