		The crystal detector is then mounted over the condenser, and the switch arm and the two studs is mounted under the condenser dial.
		The Mystery crystal set is really a definite solution to the inexpensive crystal receiver selectivity problem and all readers who build up the set have an excellent receiver possessing excellent punch and selectivity.

	My Crystal Set Page - The Thelen Channel
		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.
		This set is basically the same circuit as the set that I used in the 2006 contest except for the addition of plug-in coils and different capacitors.
		This module is just a simple dedicated switching unit to conveniently switch the antenna input of the crystal set or spotting receiver to either; the antenna, an RF signal generator (signal source), or the antenna and signal source.

	Crystal Radios "Stay Tuned" Crystal Sets
		Crystal sets by their nature are inefficient in detecting weak, distant (DX) signals.
		The BFO is connected to the crystal set by attaching a clip lead to the OUT post and loosely wrapping the lead around the crystal set’s antenna lead-in wire.
		The crystal set itself is a series-tuned front-end loosely coupled to a parallel-tuned secondary detector section.

		The number 2 was manufactured by the Brownie Wireless Co. of Great Britain Ltd. The set was available from September 1925 and appears in the 1925/6 Catalogue of the East London Rubber Company.
		The set is a cased in a fl moulded ebonite case, and must be among the very first of British wirelesses to be house in a "plastic" case.
		The crystal detector is housed at the centre of the case.

	The Knot - Registering: Crystal 101
		When choosing a crystal pattern or style there is only one rule of thumb to keep in mind: “Two-to-one” adherents recommend that if two parts on your table are ornate, such as your china and crystal, then the third part, in this case flatware, should be simple.
		Crystal also follows this principle and is placed on the table in the two-to-one format -- two elaborate patterns and one understated style.
		Champagne flutes may not be put to use very often, but a pair of crystal toasting flutes is something wonderful to have on hand for celebratory moments.

	Crystal Sets 4 - Crystal Set by Kenneth Rankin
		You normally change the frequency to which a set is tuned in to by turning the knob on the tuning capacitor, thus receiving different stations by varying the capacitance of the variable capacitor.
		There were several limitations to the crystal set: it needed a big aerial, an earth connection, the clumsy cat’s whisker, and the weak signal could only be listened to by one person at a time with headphones.
		For the crystal set itself, I first had to plan what I would be using and where the pieces would be placed (see picture and the plan drawing).

		A Crystal set is both one of the earliest detectors known and one of the earliest simplest receiver used for radio.
		It is called a Crystal set because many minerals are natural non linear devices, the traditional crystal used was a Galena crystal.
		Nowadays, crystal sets are often made with commercially available silicon or germanium diodes.

		That was a simple primitive radio whose heart was a polycrystalline lump of galena, set in lead.
		The crystal worked as a rectifier -- in place of a radio tube.

		The crystal methodologies are based on project size, the system's potential for damage, and the type of system.
		Crystal, in fact, is a non-jealous set of methodologies and runs counter to the old joke that you can negotiate with terrorists, but not methodologists.

		The crystal set is simply a tuned circuit designed to resonate at the frequencies of the AM band.
		The best thing about crystal sets is that there's almost no way to hurt this radio.

	Crystal Radio Page
		This set is a little more sensitive and a lot more selective than its predecessor due to the higher Q antenna circuit, and the ability to vary the coupling between the coils.
		This Crystal Radio was made for nostalgia purposes and it is based upon the circuit of the Mystery Crystal Set which was made famous in Australia in 1932.
		A crystal radio uses only tuned circuits to select the stations, and a crystal detector to rectify the radio station's signal to enable it to be heard with a set of headphones.

		You may have nostalgic recollections of a crystal set that you owned or built in your youth or you may simply have heard of such radios and wondered what they are all about; either way you will find something of interest here.
		Crystal sets date back to the earliest days of wireless (pre-W.W. I) and an enormous variety of circuit designs and cabinet styles have been produced over the years.
		In use, the crystal was held securely in a metal holder whilst the 'cat's whisker' was held in another small holder to which was attached a handle.

		Mike's elegant set is not only a work of art but also 'state of the art', using large diameter basketwound Litz-wire coils and high quality, low loss ceramic tuning capacitors.
		To be 'legal' in the crystal set community, the radio must be completely "passive", meaning no amplification of any form is allowed.
		One of the greatest improvements made on my own DX set was changing from a pair of vintage high-quality Baldwin phones to a pair of headphones made from an old Navy 'sound-powered' handset.

		The crystal set, like any other radio, consists of a series of stages--each with a function, each coupled to the next.
		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.
		Crystal set DX activities include discussion forums sharing ideas and results, an annual DX listening contest now into its sixth year, and the occasional set-building contest where some remarkably high-caliber craftsmanship comes to the fore.

		The headphone is a high impedance load for the crystal set and as we are working on free power from the air we can't load it down.
		The exact setting of your variable capacitor will determine a set amount of capacitance and this in conjunction with the fixed inductance of your coil we have a resonant circuit.
		As the signal passes through the diode only one half of the signal is used and the fixed.001 uF capacitor dumps the 630 Khz signal to ground leaving a very tiny audio frequency which is an exact replica of the audio frequencies (speech and music) as they originated in the radio station's studio.
