    Hello everyone. I found a TDA1083 chip in an old alarm clock, and I read on its data sheet that it works from 300 KHz to 3 MHz, so I thought I might try to make a radio that tunes from 1.6-3 MHz. I was thinking of using this design. I don't know a lot about electronics, so the only change I would know to make would be the tuning coil and capacitor. Would I need to change anything else, and is this design suitable at all?

    I moved it to radio and communications.

    I have the idea the oscilator is missing from the schematic.

    Did you also have a look at the datasheet of the chip.
    That contains a lot more schematics, including one for SW.
