It mechanically stops. It's perfectly horizontal on the low end. On the high end is the problem. The tuning dial still turns, but it simply will not move past that point. I was beginning to think I might have a mix & match radio, but the tuning needle is perfectly tacking the stations with the dial scale.

I figured if it was a different tuner, it would be be out of scale - that is if it were tuned to 640 exactly, it would not linearly track all the frequencies. I hope that make sense. But in this case, 640 and 1500 are dead-on when looking at the dial.
