I don't think its "normal" for any radio. Lets see what others with this set have to say. Sounds to me like something heat sensitive. Maybe even a bad solder joint. Since it starts when the set is cold perhaps freeze mist after warm up would find it. Turning a can of canned air upside down works pretty well as freeze mist. For a bad solder joint or cracked resistor poking the circuit with an insulated stick might find it. Not normal.
