Drake 2B Receiver 2015.01.03해당카페글 미리보기
in audio distortion as the modulation percentage increases. This is due to the detector's inability to cleanly demodulate the higher amplitude levels. Did not have a chance to investigate why the distortion numbers were significantly...

Quadrature detector 2006.04.11해당카페글 미리보기
In an FM signal, the modulation is the deviation of a carrier from its nominal frequency. The conventional method to demodulate this signal is to convert frequency deviation to phase and detect the change of phase. In the quadrature...

was probably the answer. The circuit could be simple yet sensitive enough to use a small whip antenna and could demodulate CW, SSB, and AM with the proper setting of the regeneration (feedback). I chose to make the receiver for 40m since...
