AM SW Converter with NE602

If you have old AM radio , you can use this circuit to change to Short Wave Radio, and tune the Short Wave frequency and start listening Short Wave around the world. The AM SW short wave radio can works from 1.6 MHz until 10 MHz by C1 with various values. from 150 pF until 10 pF , or you can use Trimmer Capacitor from 0-200 pF. For Crystals X1 can use 34.545 MHZ overtone crystal.

As datasheet NE602 describe , the features of this IC :

* Low current consumption : typical 2.4 mA
* Excellent noise figure : < 4.7 dB typical at 45 MHz
* High Operating frequency
* Excellent gain : intercept and sensitivity
* Low external parts count ; suitable for crystal / ceramics filter

NE602 Pin Out :
