HamComm 3.1  ^pop - DOS Freeware popular program for ham radio communications, supports reception and transmission of radio teletype RTTY, AMTOR ARQ/FEC, SITOR A/B, NAVTEX and Morse code (CW) signals. A decoder for SHIP and SYNOP reports from weather stations is also included. This program is discontinued and unsupported. Originally developped by Schroeder DL5YEC

TrueTTY Priority listing - 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) and AMTOR-FEC (SITOR-B, NAVTEX). SELFEC SITOR decoding is possible also. No additional hardware required, need only a sound card. Optionally you can use simple circuit fo PTT-control. Can cooperate with RZ4AG AAlog logger.
