Over the winter, [Michael LeBlanc] thought a good way to spend his time during those long dark nights would be to scratch build his own direct conversion receiver. He was able to find plans for ...

But the direct-conversion receiver's biggest problem relates to isolation. Any leakage in the local oscillator frequency that couples into the mixer is at the same frequency as the wanted signal, so ...

Along with the direct conversion receiver, the homodyne receiver was one of the earlier methods of building radios, both of which were superseded by the superheterodyne approach. See ...
