Many English language operators are now using the program and find it works fine for them.
Some have reported that the RTTY function performs better than MMTTY.
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.
