Be very careful with Sorcerer, it's a cracked commercial product and not
always malware
free. It will decode callsigns of P2-3 but the message remains hidden. I
think one of the
Hoka products works on P3 but the price is more than an SCS modem. I
don't have either,
had a borrowed P3 modem when I was chasing something, caught but no
official response to
the complaint.

required to make that happen.
Winlink Express' Pactor module has the capability to identify in Pactor 1 FEC
(freely decodable) at the end of a connection, but it is a user-selectable
option. The practice is discouraged in some non-amateur uses of Winlink, and I
wouldn't be surprised if most amateur users don't bother to check the box.
I understand that there is one hobbyist program out there that claims to be
able to decode Pactor 3 (Sorcerer; haven't tried it, and don't know much more
beyond that it exists)
