    Mako JE3HHT, the author of MMTTY, MMVARI, and MMSSTV, has released these applications to open source development under the LGPL license. This license enables developers and companies to use and integrate MMTTY, MMSSTV, and MMVARI, while ensuring that all improvements to source code are made publicly available.

    The MM-Open organization has been established to encourage and facilitate open source development. Anyone may create public or private branches of these applications. A set of Committers will maintain a master branch for each application; the initial Committers are Bob N4HY, Eric KE5DTO, Oba JA7UDE, and Steve N5AC. Packaged versions of MMTTY, MMVARI, and MMSSTV assembled from the master branches will continue to be available via web pages administered by Ken VE5KC:

    Source code for these applications is available via GitHub, courtesy of FlexRadio.

    Existing Yahoo Groups will continue to be used to convey defect reports and enhancement requests.

    For additional information about the LGPL license, MM-Open governance model, and development process, see

    The MM group of data programs are really nice.

    Is there a chance that MMSSTV can be integrated into a future release of Ham Radio Deluxe to replace the present poor implementation?

    Yup, we'll even GPL the source.

    We'll have to convert it from Borland style C++ to MSFT C++, but once that is done.. we can do it easy.

    This will fit well with our new snap-in DLL interface. The interface allows end users to write their own modem DLL's and we handle the rest.

    Joe Taylor is using that for the JT-65 and JT-9 modes.

    That is GREAT news to come upon! Thank you for freeing this code. Would love to see an OS agnostic version for my all Linux shack!

    Again, THANK YOU for this kind license!

    Well looks like the price of HRD will be going up , add in some free software and increase the price .

    I think if it going to be used in HRD V6... it should also be used in V5... de wb9iiv

    We've put about 200 development hours into the new snap in DLL's in 6.1. We have to retrofit that to 6.0.. which will take about 40 man hours. At $125 an hour that's $5000 of development costs just to retrofit to 6.

    We stopped development on 5 back in Feb 2013, when we released 6, but if some hams want to pay for the retrofit to 5, then we would be open to it.
