The April and May issues of Radio Age contained an insert with all the RadioActivity details and an application form. The application form also contains details regarding the Old Equipment Contest, Auction and Flea Market Policies, and local hotels. To download a copy of that insert, Click Here.
For the third year 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 registration form insert in the April and May issue of Radio Age, or to download a copy of that insert, Click Here.
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. See the insert for further details in identifying local hotels.
