Hello I understand this ICON 802 marine radio will not receive. There are two things to check for. First check the speaker jack on the back side of the receiver also check the speaker plug and the connections. Make sure that the wires are soldered properly. If you have access to an ohm meter connect it to the plug leading to the speaker, it should measure 4-8 ohms. If the speaker checks ok then check the headphone jack on the front panel. The jack has a contact switch internality to disconnect the external speaker whenever a headset is plugged in. You can clean it by using a electronic contact cleaner spray a little into the jack and plug in a headset and turn the plug back and fourth. If this doesn't work, it would be inside the unit itself. Hope this helps Bruce
