SLSRC’s Meeting & Program August 24, 2018 – Presenter, George Schindler (WBØIIS) on Amateur Digital – D-Star, DMR, Fusion and More

Digital Group will answer those questions and more in a survey of the amateur digital technologies.

George is retired from Ameren after 41 years as an Engineer, Consulting Engineer and Supervising
Engineer in the areas of Telecommunications and IT. He implemented several firsts in Missouri,
including the first Digital Land Mobile radio system and the first statewide Trunked Radio system. He
