QO-100-modem
From Signal Identification Wiki
The purpose of this project is to transfer data (pictures...) via a 2,7kHz SSBSingle-sideband modulation channel on the narrow band transponder as fast as possible. Now also including RTTYRadio TeleTYpe mode.
A characteristic feature of the signal is the presence of a 100 hertz carrier for fine tuning(not visible on the websdr waterfall).
