LANGE, * WIYDS VEX in this age Of crowded hands and sophis- ticated communications systems, there is room for the lowly regenerative receiver. The unit shown Figs.

I through is a simple receiver that Should be easy for most anyone to build, regardless Of his experience. receivers deal with this phenomenon by using a higher intermediate frequency, several IF stages and very exact tuning of the antenna input circuit.

However, you will find the SR-1 to give perkier reception with simple antennas than do many much more costly portable receivers.

suit individual needs. The short- wave receiver will accept filters with input and output imped- ances of ohms. arning to the detector circuit, D2 and D3 provide a volt bias for diode D4 and Q3. The bias keeps both D4 and Q3 slightly on, so only a small signal is nec- essary for detection, reducing the gain needed before the detector.

4.* ‚ The voltage between the transistor base and the ground is Vbe= volts plus the voltage across the emitter resistor. From the diagram above, it should be clear this is also the voltage across the resistor R2 so.

This can be done using a simple transistor amplifier circuit. Of course, there are many variations on this basic radio receiver design. Many receivers include additional filtering and tuning circuits to better lock on to the intended frequency — or to produce better-quality audio.

Micro Mini Power Amplifier Circuit. The following circuit utilizes the two flip -flops of the CD incorporated circuit to test your eyesight. -generated radio -frequency noise possesses really vast range of energy that it could be discovered by both long and short -wave receivers.

Bringing a transistor radio close to the circuit. A mixer can be implemented in several ways, using active or passive techniques. Ideally, to meet the low noise, high linearity objectives of a mixer we need some circuit that implements a polarity-switching function in response to the LO input.

Thus, the mixer can be reduced to Figurewhich shows the RF signal being split into in-phase. direct-conversion receiver, I built and tested a score of circuits. I tried product detec- tors using a single diode, a dual-gate MOSFET, a pair of back-to-back diodes, an LM, an XR, single balanced diode mixers and double balanced diode mixers.

I built a direct-conversion 2-meter receiver on a superstrip (not recommend. A very simple shortwave radio receiver circuit can be designed using circuit diagram bellow.

This shortwave radio receiver circuit is based on 2N transistors and has and has an operating frequency range between 6 and 17 Mhz. All coils are designed using an inch diameter pvc pipe and 20 gauge insulated hookup wire, L1 require 6 turns and L2 require 14 turns. Transistor Circuits I Common-Base, DC operation.

Transistor Superhet Receivers () - Sir Clive Sinclair. If, at first glance, the circuit in Fig. 2 looks somewhat like one of the simple diode and transistor receiver circuits you've seen featured in past columns, don't be too surprised.

Actually, it is such a receiver, but Ronald Wilensky (KN2ZPV), of East 17th St., Brooklyn, N. Y., has modified the basic circuit for use as an inexpensive field. Just one transistor and a MHz ceramic resonator with few other passive components.

I am making this so that I can use the short wave receiver as a functional prop for a presentation in my literature class. Oh, I forgot to include that I also tested the circuit with a wave generator.

The micro-alloy transistor (MAT) was developed by Philco as an improved type of alloy-junction transistor, it offered much higher speed. It is constructed of a semiconductor crystal forming the base, into which a pair of wells are etched (similar to Philco's earlier surface-barrier transistor) on opposite sides then fusing emitter and collector alloy beads into the wells.
