I think this is one of Nick's best videos. And he has made a lot of good ones.
This is a really excellent description of how a Direct Conversion receiver works. But more importantly Nick really captures the joy of building one of these receivers using discrete, analog components, including a Permeability Tuned Oscillator made from our beloved Glue Sticks.
Extra mojo comes in the form of a mixer designed by Pete Juliano using J310s to simulate a 40673 dual gate MOSFET. Fantastic. Icing on the cake comes from a W8DIZ AF amp out of SPRAT magazine.
There is a grand finale. I won't spoil it. Watch the video. Suffice it to say that Farhan would be pleased with this.
Great stuff. Thanks Nick!
