Remove the channel knob and remove the 16 channel stop so that the knob will continue to turn up or down more than the 16.
To bypass the 16-channel limit on the Kenwood NX-5200, you must physically remove the plastic physical stopper inside the rotary channel knob and ensure your radio is correctly programmed using the Kenwood KPG-D3N software to access more than 16 channels.
Physical Knob Modification
- Remove the Knob: Use a small pin to depress the metal locking tab located in the tiny hole on the back of the channel knob, then pull the knob off.
- Remove the Stopper: Underneath the knob, you will see a small white plastic piece acting as a physical stop. Simply pull or pry this piece out, and reinstall the knob.
Software Configuration
- Connect the Radio: Connect your NX-5200 to your PC using the programming cable and open the KPG-D1N software.
- Set Zone Channel Count: Navigate to the Zone settings in the tree view and ensure your zone has the capacity to hold up to the desired number of channels (you can have up to 512 channels per zone).
- Change Selector Limits: Go to Menu > Key Assignment and ensure your channel selector is set up appropriately, then write (program) the changes to the radio.
Note: Even with the physical stopper removed, the rotary knob will physically click and cycle continuously. You can either use the knob to scroll indefinitely or program the front/side keys as [Channel Up] / [Channel Down] to navigate.
