Slug tuned crystal radio
WebbThe system consists of two slug-tuned coils on the same frequency. The first of these coils is capacity coupled to the second which in turn is connected to the grid of the second mixer V-5. L-23, a 5. 7 MC trap is connected between the two coils to remove a spurious response that occurs at 3. 533 MC. VFO AND SECOND MIXER WebbThe slug-tuned tank coil was adjusted for maximum signal on the scope. The fine frequency adjustment trimmer capacitor was set to within 1 Hertz using a frequency counter. Afterwards, the counter was tested and accurate at zero beating WWV at 10 MHz. The calibrators are very useful with both tube and transistor analog tuned radios.

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 slug is held inside the tube by wax and if you are careful and apply slow, even pressure, the slug will move to where you want it. I now had a crystal radio put together as it should be and it worked -- sort of. Below is the schematic diagram I developed for the little radio. I'm kind of big on schematic diagrams, but I wasn't always so.
