I picked up a yellow tagged KT76A a long while back from a South East avionics shop and just got it all wired and powered up this weekend..
My question for the many that have used one of these: Is it normal to hear the high frequency whine of the oscillator inside the unit when you power it up in a quiet environment?
I do not hear it within the headsets on or across the intercom or radio...but I do hear it in the area around the plane in my quiet garage. It is not really loud, but you can tell when the unit is on. (only in stby)
