What I am attempting to do is build a transmitter and receiver unit for what the BBC is using for sending broadcast information in association with their AM broadcasts. This is called Amplitude Modulation System Signalling (AMSS). I would like to be a bit more generic than the BBC standards (allow for dynamic bit rates, allowing unmodulated an carrier, etc.). Does anybody know if this has been done using GNURadio? Is there any potential for the community to want a module to perform this task if I implement one?
Thank you very much,
Michael Berman
