XTAL Radio Receiver Circuits Page 2 RadioBanter Looking for Crystal Radio Receiver Circuits, that have a voltage quadrupler to increase headphone volume without batteries or AC power. On my original post i was, and still looking for a quadrupler circuit, How to build a sensitive crystal receiver Circuit diagram 1 Circuit diagram of the crystal receiver, which we are going to design for maximum sensitivity at weak signals. This can be a detector circuit of a 2 circuit receiver. But also a receiver with loop antenna. RP represents the losses in coil L and tuner capacitor C1 Crystalreceiver.co.uk – Your Crystal Radio Set ... Geoff's Crystal Sets – Page 2 Heart of Oak Crystal Receiver ... There is no tuning capacitor to resonate the circuit other than stray capacitance from each winding and the interaction of the length of aerial to the gound or the set itself, at least that is the theory but these radio are strange and have an almost magical feel about them. ... Crystal Radio Circuits | Crystal Set Circuits ... In some crystal receiver circuits this was achieved simply by having an additional coil on the same former so that the often lower impedance of the antenna could be matched to the higher impedance of the crystal radio receiver itself. Basic crystal radio circuit with input matching . This circuit can be seen to have an input matching ... Crystal Diode Circuits N4TRB Amateur Radio Accentuator for Exciters. 2.3 Simple Cueing Receiver .4 Ampli ... circuit. 1.2 TUBE DRIVEN LINEAR CRYSTAL VOLTMETERS Sensitive a. c. voltmeters combine a high gain, wide band signal amplifier with a rectifier type meter indicator circuit. Such meters are widely used in ... Crystal Diode Circuits 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 ... Crystal Radio Circuits techlib Below is a typical application using it with the first crystal radio circuit on this page. The amplifier provides good volume with a modest antenna. You may want a volume control as with the TL431 project! Or use the Crystal Radio RF Amplifier directly above for even more sensitivity with less than 2 mA current drain. Simple Two Transistor Radio DXing with Crystal Sets G3XBM QRP WEBSITE G3XBM QRP WEBSITE. Search this site. Sitemap. Sub Pages. Start Page. Antennas. Buying A New Radio. Codar AT5. ... With this circuit I can usually hear around 10 20 signals at night between 3 and 20MHz. Best amateur band reception (80m) so far is G2ABR at 45 miles and M0BXT at 2 miles (2 way QSO!). ...
