Hello John,
I don't think it would be technically very difficult to do something equivalent
to P3 with sound cards. I think that it would even possible to do much better
with, for example, multi-users protocol.
The problem is the time necessary to do this. An amateur can work (with

First, I would not dismiss sound card modes. I think there is much more
that can be done with them. One of the main issues IMO is that they
don't (1) adapt to changing band conditions, and (2) don't utilize FEC
as much as is possible. (We also might need much better sound cards. The

John,
You have confirmed what others already know about P3.
I sold my PTC IIex last year, when the Winmor protocol was announced to
be in development.
It should introduce an ARQ mode to compete with P3, but will not replace
it.
I had the SCS in a go kit with either a Yaesu FT-897D or and
Hi John
I have had the same experience . I have also been testing the SCS PTC2
usb modem with a pactor3. Although I love Patrick's ale400 mode , I

Hi John,
Let's reserve judgment just a bit longer. Maybe the performance of Winmor will
be good enough so that we won't need to buy the expensive modems. Maybe it
will listen before transmitting.
Now if they would modify the Winlink system so that it listened before
transmitting and there
