Questions and answers
RDR4250 radio only produces static when receiving calls from other radios
The RCA PRODIGI RDR42 Series RDR4250 radio may produce only static when receiving calls from other radios due to encryption settings. If encryption is enabled on the transmitting radio but not on the receiving RDR4250, or if the encryption keys do not match, the receiving radio may not properly decode the transmission, resulting in static. To resolve this, ensure that both radios have matching encryption settings or disable encryption if not required.
