Hi Claudio, Although there are software versions of Pactor 1 (the original FSK mode Pactor), they require using an Operating System that can control the port more directly, e.g., MS-DOS running only the one program. A friend of mine does this on an old computer and gets very good results that he claims is better than some hardware versions.
The PSK modes of Pactor (Pactor 2 and Pactor 3) have never been developed into sound card modes, because of the difficulty of exactly duplicating these commercial modes, and partly because they require fairly significant computing power and at the same time require fast switching times. The only way to buy P2 and P3 is with the commercial hardware/firmware products from SCS in Germany and that is extremely expensive, even more expensive than the cost of some rigs. In the "old days," many of us used Amtor and Pactor 1 for casual chats and even DXing, but the sound card modes have made that obsolete. Amtor is almost never used anymore as it also requires even more stringent switching, and other limitations. Pactor is still used for some e-mail connections although that will probably lessen if an ARQ sound card mode is developed that would replace it. 73, Rick, KV9U Claudio Ruben wrote: > A rookie question: What program let use Pactor 3. > > Claudio-LU2VCD >
