MMVARI was written as an Experimental program

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. Please remember that MMVARI was a beta release. That being said it is a quality program that works very well and could have been released as a final version. We are not aware of any further development of the program at this time..

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.

Installing MMVARI

A fair amount of testing is done before a new release made available on the website. In my tests, I always installed over the older versions To date I have never had any problems. That being said, one never knows for sure how an install will go on every computer.. All I can say is installing over the older version should work.. It might be a good idea to make a back up copy of Mmvari.ini and (urcall).mdt, just in case something goes wrong.


From the author, Makoto Mori, JE3HHT

I made a PC soundcard program, MMVARI, to implement the proposed scheme.
Since the objective of this project is new VARICODE experimentation, MMVARI are:

1) Implementing only basic functions for standard QSO.
2) Providing Japanese menus, but also useable in any MBCS languages.
* Non-MBCS languages, such as English, are out of scope of this project.

I would like to see the feasibility first, and after then improve the engine and cosmetics.
