70Mhz Rf Power Amplifier Circuit
The SD1143 transistor offers a gain of approximately 14 dB in this circuit. Its design takes advantage of the fact that a 175-MHz device exhibits significantly higher gain when operated at lower frequencies. The amplifier was initially intended for use...
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....
300W FM RF Amplifier Circuit
This 300W RF power amplifier for an FM transmitter utilizes 2 x TP9383 transistors. It operates within the 88 - 108 MHz frequency band.
The 300W RF power amplifier is designed specifically for FM transmission applications, providing high power output suitable...
Miniature MW Transmitter
Here is a very simple, inexpensive and interesting project which provides lot of fun to a home experimenter or hobbyist. This simple transmitter can transmit speeches or songs within a short range. The circuit uses only one transistor. The entire...
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...
Wireless Data Communication system
This project is used to communicate or transmit a text message from one place to another place through wireless. The text message is encrypted by using the Microcontroller and the encrypted message was transmitted through wireless. At the receiver end...
The AA8V/W8EXI 6CL6 One-Tube Transmitter
The operation of the 6CL6 transmitter is quite sophisticated despite the simple appearance of the circuit. The core of the circuit is the electron-coupled crystal oscillator. This circuit integrates the functions of an oscillator and amplifier into a single tube,...
Icom IC-751 RAM reprogramming
Everything appeared to be functioning normally. The half-duplex operation and pedal control in telegraphic mode allowed the operator to transmit while listening during pauses, seamlessly switching to the standard mode by simply pressing the pedal at the right moment. Previously,...
