Simon,
We have so many sound card modes now, with varying abilities to get
through under difficult conditions and do it reasonably fast (> 40 wpm).
Do you see any chance of an ARQ mode? Especially using pipelining to
decoding in the background such as was used in SCAMP?
The closest thing right now seems to be PSKmail, that runs only on
Linux. Is it possible to have perhaps a higher baud rate MFSK type mode
with ARQ and ideally would be under 500 Hz bandwidth?
73,
Rick, KV9U
