All microprocessors and
microcontrollers have a clock. That crystal oscillator is
probably what you are hearing.

Can someone explain to me why the hearing aids I have put
out a carrier at 3.84 MHz
-40 dBua/m at 10 meters
These tiny things have 2 transceivers built in.
The other one is 2.4 GIG 4 dBm eirp.
I really do not need these but they were offered to me by
the girl that gave me the hearing test so I took the offer.
I searched and they sell for $2,700.00 each/
Appreciate any information.
