Carrier-current-audio-transmitter
The choice between AM, narrowband FM (less than 15 kHz), or wideband FM (greater than 30 kHz) is determined by the specific application. FM is preferable for music transmission due to its superior noise immunity. For speech or other non-critical...
A simple tuned radio frequency receiver
This simple tuned radio frequency receiver was designed and constructed in the mid-1990s. The receiver was tested under urban and field conditions, in varying temperatures. This straightforward circuit exhibits high sensitivity, good sound quality, and reliability. A signal received by...
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...
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...
6-17 MHz SW reciever
Its very simple as It uses only 3 transistors 2n2222. The Coils can be altered to change the range of reception by lowering or highering the frequency. More: This circuit is a SW band receiver of range 6 to 17...
Telegraph Transmitter in the Pilot Radios Radio Design magazine 1930s
The TPTG transmitter has been transformed into a modern TNT model. This transmitter can utilize the existing K-111 power pack for both the transmitter and receiver, eliminating the need for a separate power supply unit. Building this compact transmitter allows...
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...
transmitter circuits 4
If the audio input is a microphone, it is expected to precede an amplifier to achieve an output power of approximately 8W. The amateur seeking to enhance a small transmitter, which is likely already constructed, can utilize this circuit, which...
remote shift light
Replacing the resistor/transistor with an n-channel power MOSFET and substituting the relay/protection diode with a light bulb results in a simplified circuit that mirrors the original design, provided one end of the light bulb is connected to +12V. If the...
