Atlas Radio Diagrams | Next Electronics

The 7th overtone of 18 MHz (17m) is 144 MHz (2m) directly within the CW region. Icarus is a high-altitude balloon (HAB) project funded by advertising revenue, which has successfully launched numerous balloons that captured impressive photographs. Robert Harrison is...

REGENERATIVE_SHORTWAVE_RECEIVER

The receiver consists of multiple subassemblies, including an active antenna, an amplifier featuring regeneration control and band-switching circuitry, an AM detector, a power amplifier, and an output device such as an internal speaker, external speaker, or headphones. Additionally, it is...

rf modem robotics project using pic16f84 microcontroller

RF technology is an exciting field to incorporate into electronic designs. However, for beginners, constructing reliable RF transmitters and receivers can be challenging. RF (Radio Frequency) technology plays a crucial role in modern communication systems, enabling wireless data transmission over various...

Loop-stick Antenna for AM band

Wound on a 3 foot length of PVC pipe, the long loopstick antenna was an experiment to try to improve AM radio reception without using a long wire or ground. It works fairly well and greatly improved reception of a...

SV3 Radio Magnadyne Radio

Most models produced in the 1930s utilize similar circuits, particularly in the RF section, which follows a common LW-MW-SW scheme. Variations among different models primarily stem from the inclusion or exclusion of variable selectivity control, the sophistication of tone controls,...

Antenna Booster for FM AM and SW Receiver

This AM/FM antenna booster circuit amplifies the broadband signal from the antenna. This antenna booster is designed to work for FM, AM, and SW receivers. The AM/FM antenna booster circuit is an essential component for enhancing radio reception across various...

4 Band Double Tuned Preselector

The circuit requires an RF input, which can be sourced from either a long wire or a loop antenna. The preamplifier operates within a frequency range from 550 kHz (Medium Wave) up to 30 MHz in the shortwave band. The...

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...

Wireless alarm FM transmitter module

There are many alarm systems available, but building a custom one may be appealing. This project can be assembled using affordable components that are easily accessible. The alarm transmitter module features a delayed trigger and an automatic turn-off function, operating...
