So we use these radios to provide audio to powered speakers. it's a stand alone radio that's really loud for playing 98.1 The Hawk across a large venue. We broke one of them at The Worlds Largest Yard Sale a couple of weekends ago. So... I figured you would like to see how to make one of these little radios not use batteries! We can't go through tons of batteries at an all day event so we needed to plug them in. One of the pre-soldered connections got yanked apart. so I fixed it all shoddy like. We aren't going for looks here, just functionality. So enjoy jacking up your battery powered radios in the future by learning how to do it above!
