A program for amateur radio digital communications via a sound card. Supported modes are RTTY (Baudot code), ASCII (7 or 8 bits), PSK31, BPSK63, 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 is required. You only need a transceiver and computer with a sound card.

A program to communicate with phone TTY/TDD devices (Telecommunications Devices for the Deaf) via a sound card, without TTY modem.

A program to receive weather reports, navigational warnings and weather charts transmitted on longwave and shortwave bands in RTTY, NAVTEX and HF-FAX (WEFAX) modes. It can decode GMDSS DSC (HF and VHF) messages. Software also can automatically save NOAA Weather Radio SAME voice messages (NWR SAME) and them digital headers. None additional hardware is required - your need only receiver and computer with a sound card.

Program to decode Morse code (CW) via sound card to text. It can work as narrow-band sound DSP-filter also.

The terminal program for CW-operators (amateur radio). You can transmit both from the keyboard and from the paddle connected to a joystick or LPT connector. While operating in paddle iambic mode sending (the memory of a unit of the symbol) is possible. The handle of the transceiver (PTT and CW keying) is made through one of the COM, LPT or USB ports. Can cooperate with RZ4AG AALog logger.
