Periodically the receiver stops receiving. I will be listening to a radio station and without warning the reception simply stops.

Sometimes it is just that frequency and if I change the frequency the reception returns and when I go back to the original station, all is good.

Yesterday, not only did reception cease, but seemed as if the receiver switched off on its own. Has anyone experienced similar anomalies? I have not been able to reproduce what happens. Sometimes switching the receiver off, letting it sit, and then turning it back on helps. I don't think it is heat as there is plenty of space on the top, sides, and back.
