"aadu" wrote in message om... hi, I'm planning to build a superhet receiver - for learning and for fun. I have looked at Doug Demaw 'barebones (QST june 82)'. Any other schematics/recommendations for first time superhet receiver project? If you have built a DC Rx, you could always convert it into a superhet by adding an IF strip, filter, mixer and oscillator. Build it as small modules - RF/mixer, oscillator, IF, etc. Start with the AF amp and work back towards the front end. Try making it for AM first with a diode detector, then add a product detector and BFO. 73, Leon |
