Hi Jim,
The bandpass knob controls (on my R-4C) a variable capacitor, and turns freely between the stops.
Good luck,

The bandpass knob on mine feels �funny�. The control seems to work fine in shifting the bandpass center up and down a several kilohertz each side of center. It turns freely up to a point but then something catches and it has much more resistance, like it has started to push a heavier assembly. If I turn it the other direction the same thing happens after turning freely at first.
Is this normal?
