Crystal Radio Circuits techlib Other pitfalls are less dangerous and relate to the receiver's performance. A common mistake when building a crystal radio is to load the tuned circuit excessively. The Q of the tuned circuit must remain high to give selectivity or strong radio stations will all mix together. Electronics DIY Electronic Schematics FM Receivers Crystal Detector Radio Receiver Set Varactor Varicap Capacitor Diode Tuned Traditionally, in a crystal detector radio tuned circuits, a mechanical type variable capacitor is used. For those of you who would like to eliminate this mechanical component, here is a modern version of the classic detector set. Crystal radio A crystal radio tuned to a strong local transmitter can be used as a power source for a second amplified receiver of a distant station that cannot be heard without amplification. [108] : 122–123 There is a long history of unsuccessful attempts and unverified claims to recover the power in the carrier of the received signal itself. A Simple Radio Receiver A Simple Radio Receiver ... The first radio receivers were crystal sets, and became available in the 1920's with the opening of Marconi's first broadcast station in Chelmsford. ... It runs completely from the energy extracted from radio waves it picks up from the antenna. A resonant LC (or tuned) circuit coupled to a large aerial or antenna was ...

For those of you who would like to eliminate this mechanical component, here is a modern version of the classic detector set. This radio, as shown on Figure 1, uses a varactor diode instead of the usual mechanical rotary device. Getting Serious About Crystal Radios | Hackaday A crystal radio  is basically a high Q resonator tied to an antenna and an envelope detector. These days the envelope detector is a point contact diode such as a 1N34 Germanium diode. The resonant... Set 7. DX receiver with two tuned circuits Crystal radio.eu DX receiver with two tuned circuits. Back to the index. This receiver has been built in three parts, each part will be described on a separate page: 1 The antenna tuner unit 2 The detector unit 3 The transformer unit. In this receiver I tried to obtain the best possible selectivity and sensitivity, by using a proper circuit and good quality ... Radio Circuits | Practical Analog Semiconductor Circuits ... Crystal radio with one transistor audio amplifer, base bias. After Stoner, Figure 4.3A. For more crystal radio circuits, simple one transistor radios, and more advanced low transistor count radios, see Wenzel Regency TR1: First mass produced transistor radio, 1954. The circuit in Figure below is an integrated circuit AM radio containing all the ... munications Receivers. Detector Circuits. The detector circuit is driven by the last IF stage which has the primary of a double tuned transformer in its plate circuit. Every detector circuit will begin with this transformer. In earlier pages we have covered what comes before that transformer. AM Detector Circuit. The simplest, most reliable, and most often used AM detector is the diode ... Tuned LC circuits Crystal radio.eu The Q of a circuit can vary from less then 100 for coils made with massive wire, up to 400 or more for coils made with litzwire. The Q of a LC circuit will decrease when we connect a antenna or detector to it, this is because the antenna or detector gives extra parallel resistance to the circuit. Quadrature Sampling Detector Phasing Receiver Circuit Salad Quadrature Sampling Detector Phasing Receiver – 2MHz to 15Mhz range – NO TUNED CIRCUITS! December 30 ... Requires no tuned circuits and is agnostic to RF below the maximum switching rate the analog switch input can handle ( see disadvantages below). ... One can use a crystal reference as low as 8 MHz but the device generates some spurious ... Understanding FM Receivers American Radio Relay League crystal discriminator—a type of FM detector containing a quartz crystal that replaces the tuned transformer in conventional discriminators. discriminator—a circuit or device in which amplitude variations are de rived from frequency or phase varia tions. The circuit has many uses, but is popular as a detector in FM receivers. Detector (radio) An early form of envelope detector was the crystal detector, which was used in the crystal set radio receiver. A later version using a crystal diode is still used in crystal radio sets today. The limited frequency response of the headset eliminates the RF component, making the low pass filter unnecessary. How to make a batteryless (crystal set) radio ... The simplest radio receiver, known as a Crystal Set, consists of nothing more than a coil, tuning capacitor, diode detector, and a pair of earphones. A typical circuit diagram for a Crystal Set Radio is given below where inductor or coil L1 is tuned by variable capacitor VC1 to the transmitter frequency. DESIGNING A DX CRYSTAL SET Antique Wireless Association DESIGNING A DX CRYSTAL SET by Mike Tuggle 46 469 Kuneki St. Kaneohe, HI 96744 3536 ... this one is double tuned (L1 C1 and L2 C2) for selectivity to tune weak DX stations in the RF ... function, each coupled to the next. The stages of a simplified crystal receiver are diagrammed in Figure 3. The resistances shown are used for detailed circuit An FM Crystal Set Electron Bunker An FM Crystal Set Updated 2010 11 28: ... It was ingenious in that, while most FM discriminators have two tuned circuits, this one only required a single tuned circuit. This was an important feature, because trying to adjust two tuned circuits when tuning to different stations, would be extremely difficult, if not impossible. ... Shortly after ... High Power Crystal Radio The receiver employs a double tuned circuit feeding a crystal diode voltage doubler detector which drives a small speaker. In operation, r.f. signals picked up by the antenna system are induced into coil L2 from the coil L1. The W0RIO Piglet 6U8A Regenerative Receiver With the crystal installed in the socket, the receiver can tune from about 7.03 to 7.05 Mhz with the sensitivity dropping off on the edges of that range. When the tuning capacitor is adjusted so that the LC circuit resonates with the crystal, one can hear the crystal "pop in" to resonance and the received signals get much stronger. receiver Will a "crystal set" work with an untuned RF ... $\begingroup$ The antenna and the tuned circuit are inseparable in a "crystal set"... there isn't really a "before" or an "after" the tank circuit. If you add an amplifier you have a 1 transistor tuned rf radio receiver, nothing wrong with that. And the 1N34s I find online say 50 V 50 mA, which is a lot of power, more than 100 mW. Amazing All Band Receiver Just replace the tuned circuit with the 10k and 100 pF as in the above schematic. Or, alternately, you can add a tuned circuit to these receivers to make a sensitive diode detector receiver for a particular band using the aircraft receiver setup. Here is another idea: Find an old AM FM radio with an antenna to house the receiver. Crystal Radio Page My copy of the Heathkit Crystal Radio of the 50's. This crystal radio is a homemade copy of the Heathkit CR 1 Crystal Radio from the 1950's. It is built in a 6 x 3 x 2 inch deep plastic box, the same size as the original. It uses a double tuned circuit with two ferrite core coils and 100 strand Litz wire. USING ELECTRONICS noniandjim USING ELECTRONICS a book of things to make . THE NATURE OF ELECTRICITY. This is a book for young people who would like to work with electronics but have had no previous experience. Anyone who can follow the simple directions in this book will be able to build radio receivers and other experimental devices described later. ... crystal detector ...

Crystal Radio and Superheterodyne Receiver the various parts of the receiver and includes two large circuit boards. Also, the large circuit boards allow ample space for modifications. [5] Even so, the crystal radio first had to be constructed in order to obtain a baseline understanding of what a receiver actually is and how it func tions.
