A simple direct conversion receiver. I have sucessfully made it for 3.5MHz, 7MHz, 10MHz and 14Mhz. I cannot give you any schematic though, since i built it completely by head, not documenting as I worked. Not very smart.
It uses a NE612 mixer, with an VFO on the receiving frequency. The receiver is quite sensitive, and due to the balanced output to a LM386 audio amp, it does not suffer very much from intermod.
