Hello Dave, I have got all the possible documentation about these two modes (Pactor 2 and 3). But in fact, I did not find the detailed specifications, only general specifications which gives several ideas about these modes but nothing more. However, I found the Pactor 1 detailed specifications (English translation of the German original specifications), which allowed me to implement it (FEC mode only).
Note: there are not the only modes without documentation... 73 Patrick ----- Original Message ----- From: Dave Bernstein To: digitalradio@yahoogroups.com Sent: Saturday, September 16, 2006 10:29 PM Subject: [digitalradio] Re: ARQ Soundcard Modes A question for you, Patrick: in your opinion, is the public documentation for Pactor 2 and Pactor 3 sufficient to allow you to build your own implementations? 73, Dave, AA6YQ --- In digitalradio@yahoogroups.com, "Patrick Lindecker" <[EMAIL PROTECTED]> wrote: > > Hello, > > >Is it just that the Pactor mode allows only a very short time > >for the ACK/NAK, or is there some synchronization from packet > >to packet that must be maintained? > The second proposal is the good one. > > >Is it possible that one could write a sound card program that could monitor Pactor II/III > >transmissions even if it can't interoperate with the SCS TNC? > If the (detailed) specifications of Pactor II and III were public, it would be possible to monitor these transmissions (but not work them, for the same problem as for Pactor 1). > > 73 > Patrick > > > [Non-text portions of this message have been removed] > [Non-text portions of this message have been removed] Need a Digital mode QSO?
