W9DYV Amateur Radio Symposiums
Interested in the full spectrum of vintage HF SSB/AM radio rig restoration, electron tubes, homebrew rig construction? Looking for just a good old fashioned Hamfest and Boneyard for a renewed sense of normalcy? The brains and masterminds behind Central Electronics always deliver!
Year after year, W9DYV Amateur Radio Symposiums routinely knock the cover off the ball when it comes to technical and homebrew equipment seminars, coupled with night-time cuisine and libations -- electronic creativity requires proper hydration and nutrition, after all!
2024 Winterfest
Friday, January 26 | 8:00 AM
Reflecting the innovative spirit of Wes Schum W9DYV (SK), founder of Central Electronics and a prime mover behind the adoption of single-sideband in the 1950s, the W9DYV Technical Symposium, in conjunction with St. Louis Suburban Radio Club's Winterfest 2024, aims to inform radio enthusiasts about the hobby’s rich technological history, encourage experimentation, homebrewing and DIY, and to introduce latest-generation communications methods and technologies.
There is no charge to attend, and no registration is required – just show up! The Symposium will be held in the Gateway Center the day before Winterfest 2024, so you will not miss the large indoor flea market, major vendors, or other forums and speakers. It is a full day chock-full of radio history, information, and how-to ideas – with the goal of increasing the number of hams and hobbyists exploring today's new frontiers just as Wes did in his time.
