I am building a 2m/6M radio receiver and studying it's design at the same time. I am "lost" when it comes to visualizing how the I/F stuff is working. I have "CircuitMaker" and wanted to create a circuit which I could simulate and see how it's working but can't find a schematic of how to do it?
I am interested in seeing how by combining two frequencies the output is "the sum and difference" etc, and the basic working of Intermediate Frequency. BTW the radio is a "dual conversion" type where it takes the input freq and converts it to 10.7Mhz then converts again to
455Khz, etc. If it matters the kit is the Elenco AR-2N6 receiver.Thanks!
