For SVRC's Thursday, March 2 meeting, we're tapping into the expertise of techno expert Michael Walker, VA3MW, for a live, two-way on-screen conversation to learn more about how and why Software Defined Radio (SDR) technology is the hottest new must-have for ham radio operators. Walker is the Customer and Training Manager for Texas-based FlexRadio, a pioneer in the design and development of SDR. As in recent months, the meeting will be held in one of the spacious and technology-equipped meeting rooms on the main floor of South Side Christian Church, 2600 S. MacArthur Blvd, Springfield, just north of Wabash Avenue. Doors open at 6:30 p.m. (park in the lot at the rear of the building and use the back entrance), providing time to mix and mingle until the program begins at 7 p.m. It's free.
