MMVARI is a multi-Mode SoundCard Ham (Amateur) Radio program for receiving and transmitting the RTTY-PSK-FSK-MFSK modes. The program was written to experiment with the efficiency of transmitting Japanese and East Asian languages (HL/BV/BY) using the VARICODE. Eastern Asia languages, such as Japanese, Hangul, and Chinese, have many characters.

This is also used within N1MM to decode PSK31 and can also be used as a stand alone program. It is quite easy to swap from MMTTY to MMVARI and vice versa within N1MM making it quite simple to use both modes in a contest.
