A switching system comprises a three-way radio switch for an onboard radio system. The radio switch includes a manual standby frequency switch that receives and displays a standby frequency input by a user; an automated standby frequency switch that receives and displays a standby frequency automatically input by the system; and an active frequency switch that shows a currently selected frequency. The active frequency switch receives and displays the frequency from the manual standby frequency switch, or receives and displays the frequency from the automated standby frequency switch. A processor is operative to monitor frequencies of the radio system in real-time; compare the frequencies of the radio system with frequencies from a database containing regional radio frequencies; trigger an alert when the frequencies of the radio system do not match the frequencies from the database; and send an updated standby radio frequency to the automated standby frequency switch.
