AMTOR SOFTWARE

MultiPSK	This is the only freeware AMTOR program I've found.  The author is French, and has approached things somewhat different from what you may be used to.  CPU usage seems less efficient than some others and requires a Pentium 166 or better computer.  If your computer is slower, this program probably will not work for you.  But it is free, and it does copy AMTOR quite well. MultiPSK also does many other digital modes.  Step by step instructions to get started with MultiPSK are HERE.
TruTTY www.dxsoft.com/en/products/truetty/	''A program for amateur radio digital communications via a sound card. Supported modes are RTTY (Baudot code), ASCII (7 or 8 bits), PSK31 (BPSK and QPSK), AMTOR-FEC (SITOR-B, NAVTEX), MultiFSK-16. HF-PACKET and UHF-PACKET (AX25) are supported in KISS-TNC emulation mode. SELFEC SITOR and DTMF-code decoding is also possible.'' (From the Author's web page)
