Simple Sinewave generator

There is simple and good way to generate quite pure sine wave:

This circuit is not very simple, but results are quite fine: output is pure sine wave. From the other side, this schematics have some minuses: it is hard to change frequency. So this type of generator is not very useful for variable frequency devices.

For my purpose I am using this generator to modulate RF. Here are some oscilloscope shots of real world hardware:

AM modulation in it’s classic way:

P.S. This device uses dual polarity power supply.
