Very interesting. It would seem that MT63 would better remain a broadcast
mode like Amtor Mode B or PACTOR FEC.

Well, maybe "I am blaming the butler", as in mistery
novels,
.
Moreover the biggest channel killer is the Pactor 2/3 QRM, not QRN or noise.

Hola Jose,
I think that Paul, K9PS attempted to do this at one time, but was not
able to finish it. He has developed ARQ criteria that was the used to
help develop PSKmail. I thought that MT-63 could handle multi-path quite
well, but I still prefer MFSK16 for difficult conditions.
While I can

Hello Patrick,
The "problem" with PAX/PAX2 is that they do not have the full ASCII
character set and they are very slow.
The timing of Windows/Linux is not so bad that you could not have a
moderate sized window. After all the SCAMP mode showed this can be done
and it had a NAK/ACK time of 0.6
