In an analogue radio that would be explained by a volume control with an
open in the resistive element. No audio until the gap is reached, then a
rapid jump to full audio because as soon as the wiper doesn't bridge the
break there's no shunt part of the control to load the series part for
low output voltage. If that's a digital radio function, it could be an
encoder problem, I guess.
