| is it possible to incorporate a pgp type program into a packet transmission. I have never done either. |

Quoted:
I understand the legalities, I was wonwondering if it was possible. And how it could be done.. ok, so we covered the legality of this issue. for PGP to work at all, the underlying transport mechanism MUST provide message integrity –– i.e. "reliable transport". for example, PGP over the internet works because TCP/IP, specifically TCP, ensures that 1) all of the bits get to the recipient, 2) they are delivered in the right order, and 3) no extraneous bits get to the recipient. hence, in order to use PGP in an amateur radio context, you must use a reliable transport mechanism. for example, PSK31 is not suitable. packet radio (specifically TCP/IP over AX.25) will work. note that some HF digital protocols incorporate FEC (forward error correction); these will work as well. ar-jedi |
