Battery Powered Tube Regenerative Receiver

The basic regenerative design is quite common. Before the schematic is created, there is a "concept stage," followed by the "available components stage," returning to the "concept stage," then moving on to the "mechanical/electrical layout stage," and finally sketching a...

MINI_ATV_TRANSMITTER

This low-power NTSC video and sound transmitter is suitable for amateur radio, video handheld transceivers, remote control applications, and surveillance purposes. It features a crystal oscillator-multiplier and a power amplifier. Video modulation is achieved through a three-transistor series modulator. The...

100W Medium Frequency Transmitter

The 100W4 is a two-tube medium frequency transmitter designed for pre-tuning to three frequencies within the medium frequency band, supporting emissions types A1, A2, and A3. In the A1 configuration, both tubes function as parallel oscillators. For A2 and A3...

REMOTE CONTROL ANALYZER

A schematic diagram for the remote analyzer is presented. The circuit operates from a basic 5-V power supply, which includes components PL1, S1, T1, a bridge rectifier made up of diodes D1 through D4, capacitor C1, and a common 5-V...

Wireless Auto Tachometer

Anyone performing their own automobile tune-ups knows how important it is to know your engine's speed. With this tachometer, you can measure your engine's speed without any connections or annoying timing lights. The described tachometer is a non-invasive device designed for...

remote control sckt

The miniature transmitter module, measuring 34 mm x 29 mm x 10 mm, is designed to operate all remote control receiver-switch combinations outlined in this project. A compact 9-volt PP3 battery can be utilized with the transmitter, which is capable...

wireless headphones transmitter

This wireless headphone transmitter ensures a reliable connection over a distance of 2 meters. The oscillator frequency ranges between 1750 KHz and 3500 KHz, utilizing a ferrite bar as the antenna. IC1 amplifies the audio signal, while TC1 serves as...

Wireless Bug detector

This fairly simple circuit makes it possible to place such a wall as a conduit to locate. It is a conduit for power, no water or gas-seeker. The only requirement is that there is tension on the line. The antenna...

Receiver-Interface Circuit For Preamps Circuit

The purpose of the receiver/interface circuit is to pass RF to the receiver through capacitor C9, while adding DC power to the feedline through resistor R2 and RF choke L7. The receiver/interface circuit is designed to facilitate the transmission of radio...
