>I agree with most of the comments expressed by Ekki, except one:
>Pactor is a commercial, non-public protocol and though it was admissible to
>experiment it in ham-bands at an early stage, I think it has nothing to do
>anymore in our bands, for several reasons, like the fact that it is very
>difficult to know the origin and the content of a transmission once two
>stations are connected. IMHO only the FEC mode (unproto) may be admitted in
>ham-bands (but in practice this mode is only used for CQ'ing...). Btw this
>explains why a certain number of Pactor-users do not really care about making
>interferences to other narrow-band users, like it happens almost every evening
>in the 3580/3583 segment...

>Now on PactorIII , I would say that even SCS agree that it is not an amateur
