First, you can simply buy a semiconductor diode. The most commonly used diode for a crystal set is the “1N34” or “1N34A”. You can buy it on Amazon at any of the following links. As you can see, they are quite inexpensive, and you can afford to stock up in order to make multiple sets.
Web19 mrt. 2024 · The secret to crystal sets is D1. In a working crystal set, the I/V characteristics of D1 near zero bias is unlike any model built-into LTSpice. A cat-whisker, point-contact detector is nothing like a Silicon diode. Spending time optimizing impedance matching, and modeling the Q of the tuner is not productive unless the detector model is … Webbeen bitten by the “radio bug” while building an AM broadcast band crystal set. In my case, I was using a galena “cat’s whisker” detector.1 Such a radio typically required a long outside antenna and ground rod or water pipe ground connection to function, even with the use of a low-threshold (0.3 V) germanium detector diode such as the ...
