Questions and answers
Is it possible for a radio channel to change back to the home setting when the power is cut off to the radio, and then restored? As an example : if the locomotive shuts down, and then restarts, temporarily cutting the power to the radio unit while it restarts. Once it restarts , power is restored to the radio unit .
