It may be possible to fix a miniature microswitch to the wavechange switch in such a way that the microswitch actuating 'pip' or roller is moved when the wavechange switch is moved to the longwave position. A cam could be glued onto the switch rotor.

Another method would be to use a light source to shine a narrow light beam through a hole in the wavechange switch to a phototransistor. A FET or relay might be needed to switch power to the Bluetooth device.
