Two transistor AM radio receiver circuit This two transistor AM radio circuit is also called “mini radio”. It uses only 2 transistors and few passive components which makes is very easy to be constructed. Although the circuit is very simple, it functions very well without external antenna or ground connection. The transistor T1 works as a feedback regulated HF amplifier and function as demodulator at the same time. One Transistor Radio Peter Vis Although this circuit uses as transistor to amplify the signal from the crystal radio, it still requires a crystal earpiece. The transistor will amplify the signal, and you will be able to hear BBC Radio 4 very clearly. The transistor used in this circuit is the common garden variety BC549C capable of providing maximum gain (hFE) of 800. However, BC547, and BC548 general purpose NPN transistors might also work as well. Three Transistor Radio Circuit Diagram Peter Vis This three transistor AM radio circuit is clean and minimalistic, and it faithfully amplifies radio signals so that you can hear them through a loudspeaker. The prototype construction was on a breadboard, and it worked extremely well. Although in this project I employ the screw cup system, it could just as easily be built on strip board. Single Transistor Radio Receiver Circuit | Homemade ... Single Transistor Radio Receiver Circuit This is probably the simplest radio receiver circuit that one could ever imagine of making. The circuit is so simple that it could be finished assembling within a few minutes and you are already listening your favorite programs over it. One Transistor Radio Schematic Circuit Diagram Here is a simple circuit for a one transistor Audion type radio powered by a 1.5 V battery. It employs a set of standard low impedance headphones with the headphone socket wired so that the two sides are connected in series thus giving an impedance of 64 Ω. Radio Circuits | Practical Analog Semiconductor Circuits ... Regency TR1: First mass produced transistor radio, 1954. The circuit in Figure below is an integrated circuit AM radio containing all the active radio frequency circuitry within a single IC. All capacitors and inductors, along with a few resistors, are external to the IC. The 370 Pf variable capacitor tunes the desired RF signal. The Transistor Radio | Nuts & Volts Magazine Engineers decided upon a case size for the new radio. Attempts were made to refine the five transistor circuit designed by TI to reduce cost and ensure that the parts would all fit in the case. One transistor was removed from the circuit and — after much effort — engineers succeeded in getting all parts to fit the case. FM Radio Circuit | Tiny Single Chip FM Radio FM Radio Circuit Design: The FM Radio circuit mainly consists of LM386 IC. This is a low voltage audio power amplifier. It has 8 pins. It operates at a supply voltage of 4 12 volts. It has an op amp internally, which acts as an amplifier. The non inverting pin is connected to the variable resistor of 10KOhms. Simple FM Radio Circuit Using a Single Transistor ... How the One Transistor FM Radio Receiver Works As mentioned above, the circuit is basically a single transistor superregenerative RF oscillator with a constant amplitude. Here we have tried to enhance the design such that the amplitude becomes considerably magnified in order to turn OFF the transistor completely during the oscillations. FM Receiver | Electronics Circuit with Full Explanation FM Receiver Circuit E xplanation Here’s a simple FM receiver with minimum components for local FM reception. Transistor BF495 (T2), together with a 10k resistor (R1), coil L, 22pF variable capacitor (VC), and internal capacitances of transistor BF494 (T1), comprises the Colpitts oscillator. Reflex Receivers Here is a two transistor radio that really performs! The first transistor acts as a reflex stage similar to the one transistor reflex radio above except that no RF transformer is used. Instead, a 10 millihenry choke sends the RF to the diode detector and the audio to the output stage. Macrohenrydyne Most Powerful One Transistor Radio Researching simple radio circuits, I found Charles Wenzel's Techlib website. There I was introduced to Robert Bazian's incredible reflex radio. Using a very high gain transistor for both radio and audio frequencies, Bazian's design had the loudest output of any one transistor radio I've ever heard. Super Simple MW AM radio circuit | Hackaday.io A one transistor MW AM radio. Another MW Autodyne Receiver. I knocked up this circuit as it claims so much (there is a version with a speaker transformer that claims loud speaker performance from two transistors) and is so simple: Regency TR 1 The circuit was designed so as to get the maximum possible gain out of the first three transistors (which operated at radio frequencies). The first transistor used as a frequency converter was operated very close to its V CBO of 30 volts (from the 22.5 volt battery). What is a Transistor: How Does It Work Radio Electronics Note on Transistor Circuit Design: The transistor is a three terminal device which offers current gain. There are three configurations that cna be used for a transistor: common emitter, common collector and common base. One Transistor Radio | EEWeb munity One Transistor Radio Here is a simple circuit for a one transistor Audion type radio powered by a 1.5 V battery. It employs a set of standard low impedance headphones with the headphone socket wired so that the two sides are connected in series thus giving an impedance of 64 Ω. Transistor radio A transistor radio is a small portable radio receiver that uses transistor based circuitry. Following the invention of the transistor , the first commercial transistor radio was released in 1954. The mass market success of the smaller and cheaper Sony TR 63, released in 1957, led to the transistor radio becoming the most popular electronic communication device of the 1960s and 1970s.

RF Radio Circuits – Circuit Wiring Diagrams RF Radio Circuits Receiver and transmitter circuits diagram for RF project, radio frequency generator and RF signal diagram ... bad for such a simple circuit! The circuit employs six transistors. The first stage is a selective amplifier, followed by a transistor detector. Two low frequency amplifier stages complete the circuit. Crystal Radio Circuits techlib Crystal Radio Audio Amplifier. Here is a simple audio amplifier using a TL431 shunt regulator. The amplifier will provide room filling volume from an ordinary crystal radio outfitted with a long wire antenna and good ground. The circuitry is similar in complexity to a simple one transistor radio but the performance is far superior. Transistor Circuit Handbook for the Hobbyist: 30 Useful ...

Smallest Radio Circuit Using Two Transistors Engineering ... Smallest Radio Circuit Using Two Transistors. Coil L 1 consist of 100 turns of 40 SWG insulated wire. Wind L 2 over L 1 which is 10 turns of the same wire. For L 3 wind 56 SWG (approx) over ordinary IFT former without using core and metal cover. Counting of turns is not necessary. Wind the wire completed over former pulley. It may be fixed on the PCB using wax. A Three Transistor Receiver American Radio Relay League conventional n p n transistor Will work, but. its low input impedance will load down the tuned Circuit, resulting in some loss Of selectivity, and the detector will tend to overload easier. One transistor FM radio project mwsherman The circuit board must be modified for the improved one transistor radio. Introduction. AM radio circuits and kits abound. Some work quite well. But, look around and you will find virtually no FM radio kits. Certainly, there are no simple FM radio kits. The simple FM radio circuit got lost during the transition from vacuum tubes to transistors. Transistor Portable Radios wa2ise A Starfire 12 transistor radio. All they really did was take a 7 transistor circuit and added in parallel a 2nd transistor to each of the original transistors except for the audio preamp stage and the output stage driver. Thus a "12" transistor! The converter circuit, 1st IF, 2nd IF, and push pull audio output stages all had paired transistors.
