______________________________________________________________Mike, as well as George, have helped me many times with glitches regarding WSJT-X. I knew Mike had ALS but didn't realize it was this far along. He was always willing to lend a hand to other amateurs having issues with WSJT-X. He will be missed.

You may not know, but Mike was instrumental in keeping the "hamlib" database, that is used in many digital communications programs, up to date - literally sometimes daily.

Sad to report that Mike, W9MDB has passed. Mike helped countless hams (including myself) by writing software, contributing to WSJT and taking time to individually help others on their setup. Information below is from Eric, WA1SXK.
Obituary for Michael (Mike) Black, W9MDB, of Quincy, Illinois
It is with deep sadness that we announce the passing of Michael (Mike) Black, W9MDB (1955–2025). A dedicated and experienced ham operator, Mike made a lasting impact on countless fellow enthusiasts through his boundless enthusiasm, technical expertise, and willingness to help anyone in need.
Mike served in the United States Air Force for 20 years, retiring as an E-7 Scientific Measurements Supervisor. After his military career, he earned a bachelor’s degree in computer science and mathematics, followed by a master’s degree in information assurance.
In 2013, while working on high-powered rocket projects with his grandson, Mike realized he needed an FCC license to operate a GPS transmitter on the rocket. Determined to move forward, he quickly obtained his amateur radio license—passing all three exams in just a few months. The hobby proved to be an excellent fit, combining his background in hardware, software, and geophysical sciences with a newly sparked passion for radio.
Mike made his first contribution to the Hamlib project in 2014 and took over its leadership in 2015. Hamlib, which provides radio control libraries used by over 20 different amateur radio programs—including WSJTX, JTDX, FLDigi, and GPredict—benefited greatly from his meticulous dedication and technical skill. He also contributed extensively to these programs themselves, as well as FLRig.
One of Mike’s notable achievements in the FT8 community was addressing the issue of unwanted audio harmonics when FT8 was first introduced. Working closely with Eric (WA1SXK), Mike co-developed a procedure that worked with virtually any radio to properly set up the audio chain and eliminate harmonic interference. Over the course of three years, they reached out personally to many operators causing these harmonics, sharing their document and guiding them to a cleaner signal. Today, harmonic issues in FT8 have been reduced to near non-existence—an enduring testament to Mike’s commitment and expertise.
In 1997, Mike married his high school sweetheart, Toni, 25 years after they first met. They enjoyed a loving life together until ALS slowly took its toll. Despite this challenge, Mike continued to show unwavering determination, love, and kindness to the very end.
Mike leaves behind a legacy of service, innovation, and friendship in the amateur radio community—his silent key, W9MDB, will be sorely missed.
Condolences may be sent to:
