For the simplest type of crystal radio, the exact number of turns doesn’t affect the operation of the radio significantly. So in the example here, if you have a 50′ spool of wire, you can just wind the coil a few turns short of 100, and the radio will work just as well. Simple Crystal Radio. The crystal radio gets its name from the galena crystal (lead sulfide) used to rectify the signals. A "cat's whisker" wire contact was moved about the surface of the crystal until a diode junction was formed.

Many years ago I purchased a crystal set kit from Orpheus Radio in Ballarat. The design of the set was based on a 1920’s naval radio and featured high-Q spider-web inductors, a variometer, mica capacitors and a rotary inductance selector switch. 1 Make Your Own Crystal Radio!

Crystal Radio Engineering Antenna and Ground System 2 Figure 1: Basic Antenna System for a Crystal Radio Distal support If available, a tree makes a convenient support for the antenna wire. A crystal radio has no added source of power--only the energy in the broadcast signal. A normal speaker requires additional power from an amplifier with an added power source, like a battery or power from a wall socket. An earpiece needs much less power than a normal speaker and can make enough sound to be barely heard. Some circuits use a crystal radio circuit to detect and tune the signal

Much of this project was based on a "Mystery Crystal Radio" from the 1930s and the ARRL Handbook of 1977 . This is all highly experimental and I can promise the outcome will vary, but it will work. One final note on this coil is the two output connections (a, b) can be reversed for better volume. With SSB, it is much harder to make out ham callsigns with just an envelope detector, but there are some colossal signals on 21, 28 and 50MHz when conditions are good (e.g. in a strong sporadic-E opening) which might just be identifiable at range on a crystal set.

Build a Crystal Shortwave Radio. This project combines two popular themes from radio history—crystal radios and shortwave (SW) listening. It's designed from scratch by our non-resident engineer Walter Heskes. Crystal radios get their power from the radio signal themselves. There's no need to supply batteries or plug into a wall socket. I originally got into them to see how much power they could produce as part of my interest in non-conventional energy though I quickly abandoned that effort due to …

    Amateur Radio came with the invention of the quartz crystal. It consists of a thin slab of rectangular quartz. The crystal is placed between two electrodes and enclosed in an insulating case or holder (see Fig. 2). When the crystal is excited electrically, as in an oscillator circuit, it vibrates. The operating frequency is determined by the number of times per second the quartz vibrates.

    So, 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 The simplest radio is a crystal set which actually makes use of the radio waves electrical energy to power it and so does not need a battery. It only works well if we have a very large antenna and if the radio signals are strong. A crystal set radio is composed of five basic parts; an antenna (and earth), coil, tuning capacitor, detector and an earpiece or headphone:

    Fun With Crystal Oscillators: Part 1. To get things kicked off, I thought it was best to start where I started. Shortly after getting into shortwave radio listening, I wanted to create a radio … Crystal Radio Engineering Designing an air-core Inductor 2 where d is the coil diameter in inches (center of conductor to center of conductor) Example: What is the inductance of a coil has a diameter of 2.5 inches, a length of 2.33

    With SSB, it is much harder to make out ham callsigns with just an envelope detector, but there are some colossal signals on 21, 28 and 50MHz when conditions are good (e.g. in a strong sporadic-E opening) which might just be identifiable at range on a crystal set. receive with the crystal radio is measured in billionths of a watt, but that is plenty of energy, because the human ear can detect sounds that are less than a millionth of even that.

    I have heard, even from a physicist, that it is impossible to build FM crystal radios. On the other hand some experimenters claim that they have built them. This argument intrigued me to try and build an FM crystal radio, which I have done successfully. To my surprise, the result is an astounding performer, pulling in four local stations in Tucson. When connected as a receiver to a good sound crystal radio page for basic construction tips). Use a scrap of paper or cardboard as a template for getting the tuner/slider the correct size. Sand off the varnish on the coil where the slider will touch it. Connect the ground and antenna, hook up the headphones, and through much patient adjustment of the detector and slider, you should eventually be able to pick up broadcasts. A capacitor
