Simple long-distance wireless FM microphone circuit

The loop antenna L1 is utilized for emission and also functions as the oscillation coil. The high-frequency current flowing through the antenna is synchronized in resonance with the oscillation frequency, ensuring optimal emission performance. Practical applications indicate that the effective...

LW, MW and SW bands Receiver

This is a compact three transistor regenerative general coverage receiver with fixed feedback. It's based on the principle of the ZN414 only much higher coverage. The sensitivity and selectivity is relatively good (especially on the LF and MW bands) as...

136 kHz QRSS receiver

For digital modes, the ideal receiver should be straightforward, featuring front-end selectivity, manually adjustable gain, and an IF filter. Many functionalities found in HF receivers can be implemented through software. In the collection of components, there was a surplus 1.4...

Energy-sucking Radio Antennas

Here's something that has always bugged me: light waves are about 5000 Angstroms in wavelength, while atoms are more like 1 Angstrom across. Atoms are thousands of times smaller than light waves, yet atoms obviously interact very strongly with light....

Radio Glen Transmit Selector system

The main box of the Transmit Selector system is designed to be located in the technical rack of a small radio broadcast station. There are four stereo balanced line inputs, either of which can be routed to a stereo balanced...

Noisy Regen Receiver

The following circuit illustrates a Noisy Regenerative Receiver Circuit Diagram. Features include a Noisy Regenerative Receiver Circuit, which simplifies the process of... The Noisy Regenerative Receiver Circuit is designed to amplify weak radio frequency signals while also incorporating a regenerative feedback...

FM Wireless Microphone

The frequency range for the FM broadcast band is 90 MHz (megahertz, or 90 million cycles per second). An FM microphone utilizes a variable tuned circuit, allowing it to be adjusted to a quiet frequency within the local FM broadcast...

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...

schematic of programmer radio

This time, information will be shared about the schematics of radios, specifically the schematic of a programmer radio, along with the latest information available on Onmilwiki. The schematic of a programmer radio typically includes various components essential for its operation, such...
