100.3 The Beat St. Louis Becomes The Sound

A site dedicated to format changes? Why not; what's more historic than when something begins or ends? The Format Change Archive is your home for airchecks of the beginnings and endings of some of the most historic radio stations (and some you may never have heard).

If you have an aircheck that you'd like to donate for exhibition here, send us an email with the details! We'll respond with detailed instructions on how to proceed.
