The older converters use a low (audible) switching frequency. If the output was 
not filtered with a large enough capacitor the voltage ripple from the 
converter could be heard through the radio. With the advent of high speed 
electronic switching DC-DC converters the switching frequency is up to 300 Khz. 
Normal hearing is 20 Hz to 20 kHz.
