The April and May issues of Radio Age will contain an insert with all the RadioActivity details and an application form. To download a copy of that insert, Click Here.

For the first time ever, we will have RadioActivity vendor spaces inside, with air conditioning! Vendors may register for spaces in the parking lot ($20 for two spaces) on the covered patio ($25 for one space and table), or inside the gymnasium ($30 for space and one table). Additional tables can be rented. Only venue tables maybe used in gym and patio. One advance notice: The Byzantium does not allow food or drink in the gym at any time. The number of inside spaces is limited, so register early. Use the form coming in the April issue of Radio Age.

The indoor auctions feature some of the best items of the year. Our auctioneer will take the Saturday morning walkaround auction to all the vendor spaces.

There are several hotels within five minutes of the Byzantium venue. We expect to have a reduced group rate for at least one hotel near the venue. We will update you with another email.

Some of the vintage electronics manufacturers from theDelMarVa/DC area include: Watkins-Johnson (Gaithersburg), Westinghouse (Baltimore), Astron Corp. (Herndon), Sperry Marine (Charlottesville), T-Com (Columbia, MD), Adams-Russell (Herndon), Melpar (Falls Church), Litton (College Park), Racal (Rockville), NEMS-Clark (Rockville), Frederick Electronics (Frederick, MD), Weinschel Engineering, (Silver Spring), DOFL (Diamond Ordnance Fuse Labs, Silver Spring), Bendix (Baltimore), ERCO (Riverdale, MD), AM (Aircraft Armaments, Inc) (Hunt Valley, MD), just to name a few. Thanks to Ed Lyon for this partial list. Ed will give the banquet talk “Electronics from Washington’s Own Silicon Valley.” Do you have something for the Old Equipment Contest related to this theme?
