It is a direct conversion receiver but I changed LM386 to 2N3904. The X on a .01uf capacitor means it is totally removed. The tuned inductor is DIY7 series with built-in capacitor. I built 7.050 MHz version so I used DIY7-7. You can also use toroid coils of course. The major part of this design is the 2N3904 audio amplifier. It is biased by NE602 and it is driving a low impedance headphone. Also, it is very rare to switch power like that, but my result seems to be very positive. Thanks, Adam
