Under the pseudonym YONIQ, a new version of the popular MMSSTV software for communication via slow TV sweep or SSTV was born. The idea is to provide the popular software with certain functionalities, to a greater or lesser extent, demanded by many of its users over time. (MMSSTV -; YONIQ)

YONIQ maintains the charm and most functions of the original software, but also provides you with other functions that manage to place you within the segment of utilities intended for 21st century radio amateurs. A necessary and powerful update since the release of version 1.13 10 years ago. This has been created from the implementation of new code and modification of some of the source code provided through GITHUB under GNU license, as indicated in .

YONIQ is not a new program, it is a continuation and update of the wonderful work done by JE3HHT which it named MMSSTV. It is simply a version of the original software, sharing its GNU license as is the wish of its original creator Makoto Mori.

Some of its novelties include:

  • Implementation of the Omni-Rig system for transceiver control.
  • Spanish and English languages.
  • Download data from
  • Storing frequencies as a memory.
  • Compatible with different logbooks.
  • Indication of the percentage of image sent and received.
  • Improved image reception settings.
  • Modern visual interface.

The project has worked from different situations and conditions, starting with the modification and programming. The code was tested by a volunteer team that has dedicated their time altruistically, for several months, so that the project saw the light in the best possible way. Thanks to this, a more effective configuration has been achieved for the reception of image. This means that more PC resources need to be used. However, if you are using a low-resource or perhaps an old computer, you can always reconfigure the options to run like previous versions.

Both the YONIQ version of the MMSSTV program and the official original versions are available downloads here:

Most operators who are familiar with the original MMSSTV, should not have any difficulty using this new version.

For support and consultation on the new functionalities of this version in English, it is recommended that you use the MMSSTV forum on -

It should be noted that YONIQ is still a prototype and, therefore, its creators are responsible for the use of this software or for any damage it may cause, let alone the creator of the original software. It is the sole responsibility is the user for all aspects of using this program.

· Note that YONIQ -MMSSTV was not originally written for English users and will install using the Spanish language.
The provision for using English was added later but requires changing language after the program is installed.
To simplify this, I have made the English instructions below. Following the instructions and pictures will help you with
selecting the correct buttons. After you finish the install and change the language to English you will no longer have a problem

(This will bring back memories to some early users when the MM project started, MMTTY & MMSSTV were only in Japanese)
