Radio Glen Transmitter
This document describes the transmitter system supplied to Radio Glen for testing as designed and constructed by Henry. The transmitter is supplied in prototype form and has the physical limitations of an instrument constructed using prototyping techniques. The transmitter has...
14W CW TRANSMITTER
A low-power two-stage FET transmitter designed for the 80-meter amateur band utilizes a Pierce crystal oscillator that does not require an output resonant circuit. A DC milliammeter can be connected across a 150-ohm resistor in the gate circuit of the...
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...
Bandswitched Grid Dip Meter
This circuit is designed for checking resonances in tuned circuits, antennas, and similar applications, covering a frequency range of 2 to 20 MHz. Q1 acts as an oscillator that can be tuned across this range using capacitor C1 and band-switched...
GBPPR 1 GHz RF Spectrum Analyzer
An RF spectrum analyzer is an essential tool for experimenters. The spectrum analyzer project described here is an enhancement of the "Spectrum Analyzer for the Radio Amateur" (Part 2) project by Wes Hayward (W7ZOI) and Terry White (K7TAU), which appeared...
4 Channel 433MHz Wireless RF Remote Control Kit 200m
4 Channel 433MHz Wireless RF Remote Control Kit with a range of 200 meters. This RF remote control offers an extended range of up to 200 meters (650 feet) and is versatile for controlling various devices.
The 4 Channel 433MHz Wireless...
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,...
remote control sckt
The miniature transmitter module, measuring 34 mm x 29 mm x 10 mm, is designed to operate all remote control receiver-switch combinations outlined in this project. A compact 9-volt PP3 battery can be utilized with the transmitter, which is capable...
DF data transmission module and the super-regenerative receiver module
The DF data transmission module operates at a frequency of 315 MHz and utilizes a surface acoustic wave (SAW) resonator for frequency stabilization, ensuring high frequency stability. The frequency drift remains minimal, at only 3 x 10^-6, across a temperature...
