    Why is my Audiovox Radio receiving unwanted signals?

      sbarnettJul 30, 2025
      Your Audiovox Radio might be picking up unwanted signals because the CTCSS privacy mode is not activated. To resolve this, turn on the CTCSS privacy mode and set the code number to match the setting of the target transceiver. Alternatively, interference from electronic devices like computers or TVs could be the cause. Try turning off these devices or moving farther away from them.

      Linda RivasAug 6, 2025
      If your Audiovox Radio has a weak or no signal, several factors could be the cause. First, ensure that the batteries are adequately charged; if weak, charge or replace them. Second, verify that the channel and privacy code are set the same as the target transceiver and adjust the transceiver’s settings to match those settings of the target transceiver. Also, check that the volume level isn't too low and that the PTT button isn't inadvertently depressed; increase the volume level and release the PTT Button. Finally, excessive radio interference or obstructions might be present; try changing to a different channel and avoid operating in or near large buildings or vehicles.

      Michael EvansAug 22, 2025
      If your Audiovox Radio isn't transmitting when you press the PTT button, it could be due to weak batteries. In this case, charge or replace the batteries. Another possible cause is incorrect battery polarity. To fix this, install the batteries following the directions in paragraph Installing the Batteries.
