The software Packet-Radio TNC

I am developing a software dual-port Packet-Radio TNC that uses a soundcard as a modem and supports AX.25 protocol. It has been tested on Windows XP, Vista, 7, 8, 10 and has proved stable in operation. The Soundmodem has two TCP/IP interfaces to link with client application: AGW PE and (X)KISS. In case of AGW PE interface, this modem is a direct replacement of original AGW Packet Engine and emulates AGW PE API. The Soundmodem may be used to build EMCOMM, APRS, BBS, Node station, for satellites etc. It supports such modes:

Soundmodem AFSK 300, 600, 1200, 2400 baud. (D)BPSK 300, 600, 1200, 2400 baud. (D)QPSK 2400, 3600, 4800 baud.

High-Speed Soundmodem G3RUH 9600, 19200 baud. Manchester 1200, 2400, 3600, 7200 baud. HAPN 4800 baud. GOMX-1/3, Mobitex-NX (BeeSAT-2/4), AAUSAT-4, LilacSat-2 decoders
