Occasionally I get a whine / hum from dab radio .. Anybody else ? Gets quite loud at times
 
No reception .. Sounds like heater fan kicking in but turn down volume and noise goes away

Does it also seem to kick in when you turn the ignition off?

Could be a cooling fan for the amplifier?

Low volume = less power = less heat, so no fan noise?

Maybe, think the CD player in the glovebox keeps spinning for a while even after switching off.
