CLOVER-I was the first iteration of the Clover series of digital modes. Was never released for commercial use, replaced by CLOVER-II. Also known as Cloverleaf. Developed by Ray Petit, W7GHM in 1987, taking inspiration from Coherent CWContinuous Wave.
Note: The audio and visual sample provided is an estimation based on a CLOVER-II sample. It is NOT a raw CLOVER-I recording. No known recorded samples of the original CLOVER-I exist to my knowledge.
The CLOVER-I system uses a single tone Phase (PSKPhase-Shift Keying) or Phase-Amplitude (QAMQuadrature Amplitude Modulation) shift keyed signal to deliver up to 100 bpsBits per second (bps). Channel spacing was 100 HzHertz (Hz), unit of frequency, defined as one cycle per second (1 Hz)., no guard bands were required with this mode.
Decoding Software[edit]
None so far. Please add one if you know one.
