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), BPSK63, QPSK63, BPSK125, AMTOR-FEC (SITOR-B, NAVTEX), MFSK16, MFSK8. HF-PACKET and UHF-PACKET (AX25) are supported in KISS-TNC emulation mode. SELFEC SITOR, AMTOR-ARQ (SITOR-A) and DTMF-code decoding is also possible. No additional hardware required - you need only transceiver and computer (Pentium-100 or better) with a sound card. Optionally you can use simple circuit fo PTT-control. It make fast and convenient frequence control, has a lot macros for tramsmitting. Can cooperate with RZ4AG AAlog logger.

Recent Changes: The "Narrow" option was added into "Filters" menu in RTTY and ASCII modes.
Narrow filters can be useful to eliminate interference from strong near frequency stations.
