This is an rf generator with am modulation and very low distortion in audio and  carrier.
This is the heart of a very high quality mw transmitter.
The next stages of a 40w(160wpep) transmitter is included in a schematic with this module.
The frequency change with a rotary encoder.
The step changes when press the push button and rotate the encoder.
For other frequencies and offset ask us.
