FM Crystal Radio Receivers. Radio, 2002, 7. The notion of "crystal radio" is strongly associated with huge antennas and radio broadcasting on long and medium bands, in this article, the author describes the experimentally tested detector circuits of VHF receivers designed to listening to a FM stations. For a crystal radio receiver on the AM band (550-1600 kHz), it is rarely possible to get an ideal tuned antenna. For example, a new 10 kW AM transmitter antenna is being built in our town, and it is a quarter-wavelength vertical tower, 165 feet high (for 1490 kHz).

    DESIGNING A DX CRYSTAL SET - Antique Wireless Association

    In fact, DX crystal set performance is comparable to any other radio (powered or not) short of a full-blown communications receiver with its own outside antenna. The rule of thumb is, if you can hear them on a radio, you can hear them on a crystal set. The best times to listen are at sunrise and sunset, when stations are signing on or Basic crystal radio circuit . There are four main areas to the overall radio operation: Antenna / earth: Although the antenna / earth system is not actually part of the crystal radio, it is an essential element in seeing how the crystal radio works. The antenna picks up the signal which is used as the input to the radio.

    Electronics Projects: How to Add an Antenna to a Crystal ...

    A good, long antenna is an electronic component vital to the successful operation of a crystal radio. In general, the longer the antenna, the better. If possible, try make your antenna at least 50′. Longer is better. You can make your antenna from just about any type of wire, insulated or not. RadioShack sells a […] The antenna should be straight, though you'll likely have some near the crystal radio itself which isn't lined up with the rest of it. Pointing it at a radio station gives best results for picking up that radio station, but that isn't always possible and so it isn't likely you'll be doing that. Welcome to my cylinder coil page. For most of my crystal radio career, I have focused on using spider coils. I still really like them, but other types of coils are fine too.

    Making a suitable antenna for a crystal radio - Electrical ...

    The simplest antenna for a crystal radio is a long wire (say 10m), and up as high as you can get it. On the roof is best if you can get up there. The wire should be stretched out, not rolled up. Outside is best, to avoid signal loss in any metal in the building's structure. Make sure the antenna is attached with insulators at both ends. The tuned circuits in a crystal radio are composed of a coil (inductor) and a capacitor, usually variable, to allow tuning the circuit to the desired frequency. A crystal set can be made with a single tuned circuit (the detector coil), or with an added tuned circuit (the antenna coil) as shown in the above diagram. In this science project, you will build your own AM radio receiver from scratch and use it to listen to AM radio broadcasts. With your crystal radio you will be able to experiment with the circuit and the antenna to get the best reception. Objective Build a simple crystal radio receiver and experiment to improve your reception.

It is not only a functional crystal set but it looks nice too. Crystal Loop Radio Schematic See more For crystal a radio, you need a good quality germanium diode, which will provide a nice strong signal. The best diodes that provide the strongest and clearest signal were vintage ones that had been recycled out of old radios. The large 8 mm long, glass diode shown above, has two red bands, similar to a resistor colour code, signifying 22. It ... This Crystal Radio is highly selective as to separating stations and tunes in the A.M. band from 570 KHZ up to 1.7 MHZ and the short wave bands up to 2.5 MHZ. It is suggested that crystal earphones be used….. or (preferred) feed the audio output of this tuner into an audio amplifier.

    High Sensitivity Crystal Set Build a “crystal radio” that does not require an outside antenna or ground by using a new zero-voltage-threshold MOSFET. Bob Culter, N7FKI the circuit topology, which was motivated by a similar circuit using a JFET and battery gate bias configuration developed by David W. Cripe, NE4AM (formerly KC3ZQ).4 The Performance can be optimised by choosing a diode with a low forward voltage drop and adjusting the antenna matching winding for the best compromise between selectivity and sensitivity. Some recent developments have been the use of special zero gate bias MOSFETs as sensitive crystal sets (no power applied).

    Tuning Coil Construction High Selectivity Crystal Radios

    construction of coils for high selectivity crystal radio. Tweet. When I was a kid I built my first crystal radio. It had no tuning capacitor, it brushed a metal contact across a copper coil where the varnish had been sanded off with sand paper. There are few truly magical things in this world that are practically free. This DIY AM antenna is best used outdoors but you can make it work inside by somehow re-routing the wires. It amplifies all weak AM signals, so a powerful local station might be heard over your entire AM radio dial. Here is…

    Crystal Radio with Loop Antenna - philpem

    Well, the crystal has no energy in it, but the radio waves do. If you are close enough to the transmitter (light intensity gets weaker the farther out it propagates) and you have an antenna capable of extracting the energy, then the crystal radio can turn the radio energy from the transmitter into sound energy in the earphone.

    Crystal radio - Wikipedia

    A crystal radio receiver, also called a crystal set, is a simple radio receiver, popular in the early days of radio.It uses only the power of the received radio signal to produce sound, needing no external power. It is named for its most important component, a crystal detector, originally made from a piece of crystalline mineral such as galena. This component is now called a diode. A "crystal set" is a radio receiver that operates using a crystal (diode) to extract the audible sound from the power that the radio station is transmitting. ...
