Logger 32  ^pop - 32-bit Amateur Radio logging program written by Bob Furzer, K4CY the author of Zakanaka. Logger32 runs under Windows 95/98, Windows 2000, Windows ME, Windows NT and Windows XP Logger32 has been developed to be a highly user configurable general purpose Amateur Radio logbook with computer control support for many radios and antenna rotators.

59+ CW  ^pop - Freeware Win32 application can be used for sending CW signal to the transceiver over a COM port or simply listening to Morse code on the speaker. The application is very easy to configure and will allow you to you to add new Morse characters set speed, tone, dash, dot, PTT line delay and other parameters. It is also possible to set shortcuts for call, QTH, name, RST and ANY other QSO field.

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.
