WWV Radio

The tuned circuits of capacitance and inductance used in vacuum tube transmitter circuits are often referred to as "tank" circuits, as they serve as reservoirs of RF energy. Blocking capacitors are employed to create a high impedance path for...

This is an FM radio receiver circuit that can be used with a PC. The circuit includes several regulations: A) The P1 potentiometer is used to adjust the sound intensity. B) The P2 potentiometer is used to adjust the...

The RF design and construction of radio frequency oscillators. Radio frequency (RF) oscillators are essential components in various electronic systems, generating signals at specific frequencies used for communication, signal processing, and other applications. The design of RF oscillators involves several...

This is an experimental work to monitor a spectrum pattern of radio band, and is a continuous project from Audio Spectrum Monitor. To analyze the spectrum of an input signal, I chose an Atmel's AVR microcontroller used in Audio...

A simple FM CB radio receiver can be constructed using the electronic diagram provided. This FM CB radio receiver circuit utilizes a TCA440 integrated circuit and operates at an intermediate frequency of 455 kHz. The input filter is a...

The modification presented involves using a 2N2219 NPN transistor to replace T2 and a 2N3553 NPN transistor to replace T3. Both transistors are categorized as VHF transistors. It is necessary to attach a heatsink to the last transistor. No...
