Using live or neutral wire in AC household wiring as receiving antenna. Of course, this is possible only with high voltage capacitor inserted between the receiver antenna terminal and live or neutral wire. AC wiring antenna solution was mentioned as some.... -
AM radio receiver circuit employing FM IC chip as the main component. This AM radio receiver circuit uses hand-wounded coils to tune the frequency at AM bandwidth.. -
A simple FM Radio circuit with diagram and schematic using IC TDA 7000. This low cost single chip fm radio circuit design is easy to make and is suitable to make a FM portable radio.... -
A valve radio receiver in its crudest form is a frequency determining tuned circuit, (consisting of an inductor and capacitor in parallel) followed by a series of valves coupled together. These valves act on the signal and provide high frequency.... -
Transmitter FM 45W with valve. TECHNICAL CHARACTERISTICS: Tendency of catering: 220V AC Frequency of emission at FM: 88~108MHz Force of expense: max 45W (without the... -
Here is a simple USB FM transmitter that could be used to play audio files from an MP3 player or computer on a standard VHF FM radio by connecting it to an... -
A simple little three-transistor FM wireless microphone / room bug that can really throw-out quite a signal. With a wide tuning range from 80 MHz to 120 MHz, this little device can transmit anywhere within the FM broadcast band (88 to 108 MHz) and can be.... -
One crude method for distance measuring is by using an ultrasonic transducer. the principle is that u send a burst of ultrasonic wave in the direction of the object and it is reflected back to the ultrasonic receiver. by measuring the time delay from.... -
LVDS receiver needs a failsafe function to avoid uncertain output state when it has an improper connection. In this appnote, we examine the circuits and characteristics of three popular failsafe functions: external-biasing, in-path, and parallel.... -
Second, I have found that when the receiver was centered in the brightest spot (middle) of the reflected laser beam the circuit worked poorly compared to when the receiver was placed off-centered. This probably indicated that the circuit was saturated when.... -
This is an oscillator circuit that can be used for calibrating frequency counters, amateur receivers and frequency meters. This circuit is called 2MHz standard with dividers circuit. This circuit uses two crystals, 100kHz and 2 MHz. Here is the schematic.... -
Designed around the popular ZN414 ic this receiver covers the AM band from 550 - 1600 KHz with the values shown. For Longwave the coil needs to be changed. Use one from an old MW radio to save time. The ZN414 is a tuned radio frequency designed and.... -
wireless audio and visual transmission to a TV. The TV acts as a receiver, eliminating the need to buy a separate monitor. You can also hook it up to a VCR or CCD Camera, and even set up a remote CCTV security system Q3, VC1, C13, C16 and L3 all make up a.... -
A design for a synthesised ATV transmitter covering the 13cm band and beyond up to about 2. 6 GHz. This transmitter has been designed for optimum video performance and can achieve a broadcast quality signal when received with a professional TV microwave.... -
This is a 25 Watt basic power amp that was designed to be (relatively) easy to build at a reasonable cost. It has better performance than the standard STK module amps that are used in practically every mass market stereo receiver manufactured today. When I.... -
The overall task of the optical receiver is to extract the information that has been placed on the modulated light carrier by the distant transmitter and restores the information to its original form. The typical through-the-air communications receiver can.... -
A noise generator with a wideband output signal is always handy to have around when you`re adjusting receivers and other types of HF equipment. Simple RF Noise Source Circuit Diagram: read more †’.. -
This circuit will explain the PLL controller unit for the FM transmitter. It is very important since the transmitter frequency is digitally controlled and thereby very stable. The heart of this unit is a PIC processor called PIC16F870, a 2 x 16 char display.... -
simple and powerful FM transmitter is a interesting project using one transistor range of 100 M circuit diagram with description of FM transmitter various interesting project... -
This FM spy telephone circuit is mounted serrial with the phone line. When is signal on the wires this transmitter will radiate airwaves thru the wires wic.... -
A simple circuit which is switchable between a sharp cut-off above 2. 5 kHz and a narrow bandpass around 800 Hz. In the low pass (LP) state it can be used on speech as the filter section of a direct conversion receiver. For CW operation, the cut-off.... -
Here`s BH1417 USB FM Transmitter with built-in PLL circuit. Its low-frequency signal is converted into high-frequency, which can take any audio device with FM radio (stereo, car CD, MP3, DVD player, etc.), as a normal radio station. Transmitter power is.... -
The whole system was built in a package that was about 70mm x 96mm x 30mm which contained the TNC, transmitter, interface circuitry and a lithium battery sufficient for about 20hours of continuos operation. All in weight (including battery and antenna) was.... -
Build this circuit using a Digi-Key Electronics Barrel Crystal (CA-301), 15 Mhz for a standard output frequency of 150. 00 Mhz. If you want to customize the frequency, follow the directions below. I usually build this circuit to operate between 150 to 165.... -
The ML7005 is a multi-functional DTMF transceiver LSI with built-in a DTMF signal generator, a DTMF signal receiver, a call progress Tone generator, a call progress Tone detector, and a FAX (FX) signal detector. Each functional block CAN be controlled by an.... -
The most important part of this 88-108 transmitter is the Colpitts oscillator. C3,C4,C5,C6,CD1-CD2 ans L1 determine the transmission frequency. The RF Osci...
