Adding FSK modes. #5

Closed kg4sgp closed 9 years ago

kg4sgp commented 9 years ago

I was wondering what kind of process would be needed to add a FSK mode. We are looking to use minimodem to communicate using DominoEX as apart of our high altitude balloon telemetry. (We already use minimodem in our RTTY telemetry recieve station for our current flights :D ). Any pointers would be greatly appreciated!

Thanks! KG4SGP - Jim

Minimodem's core FSK algorithms handle only binary FSK (two frequencies) -- so adding additional binary-FSK-based modes is feasible.

DominoEX, however, is a multi FSK (more than two frequencies) mode. Extending minimodem to support MFSK modes would require a new implementation of the core FSK decoder algorithms (and I have no plans to do such, sorry!).

Not a problem and thanks! :)
