WebbThe sensitivity of a good crystal set is about 500µV for minimum discernable signal. A big issue is lack of selectivity. Various improvements are possible using full wave bridge detectors and antenna matching circuits together with the use of high Q tuned circuits optimally coupled to the detector and antenna. WebbThe variable capacitor has large inter-meshing plates that are subject to mechanical damage or vibration and is physically a large component (size matters). The range of …

WebbSo, what makes a crystal radio a "DX" set? Well, this one is double-tuned (L1-C1 and L2-C2) for selectivity to tune weak DX stations in the RF jungle we now live in. Some DX sets resort to triple tuning for even more selectivity -- depends on how many hands you have to do the tuning.

WebbAnswer (1 of 3): In a superheterodyne receiver the bandpass filtering of the unwanted signals is performed by the tunable RF filter and the Intermediate Frequency (IF) filter. Since the IF filter is a fixed bandpass filter, it has a much tighter passband than the tunable circuit. This allows a ve...
