How to install echo board in a Galaxy 2517 - Galaxy Radios DX-2517 CB Radio. Created by james-weckerly. Radio Communications - Galaxy Radios - DX-2517 CB Radio

This radio already has an echo board installed in it from the factory. On the bottom set of knobs, left side, over three knobs. That knob is your echo/delay knob. No need to install one. Just turn it on.Hope this helps.
