Drfeelgood,
1. Is this transmit only, receive only or both? I assume it is receive only.
Check your speaker connections and the extension speaker jack. A wire may have come loose or the jack has lost the spring tension that keeps two of the contacts closed. If using the internal speaker it needs these contacts to be closed in order for the speaker to receive audio.
If you are using internal speaker trying plugging an extension speaker in and see if this fixes the problem. If it does then the problem is either the jack or the speaker has died. If not, the problem is then a tad more serious and may warrant a trip to the radio doctors. |
