RF Cafe visitor David M. requested the scanning and posting of an article from the January 1963 edition of Popular Electronics, authored by Philip Hatfield from the Receiving Tube Department of General Electric. The article describes a straightforward design utilizing...
200W 136 kHz transmitter
Output transformer core sourced from a flea market, light blue in color, marked as A-438281-2-9H9-3, with an outer diameter of 47 mm, an inner diameter of 24 mm, and a height of 13 mm. No data is available regarding the...
RF Actuated Keying Monitor
Sending Morse on a rig without a sidetone is not impossible, but is not particularly pleasant either. This battery-powered monitor has been designed to provide an audible indication of keying for those whose rigs lack a CW sidetone. Its sensor...
Simple RF Transmitter
This schematic represents a tone transmitter. When using sufficiently small resistor values, it generates a tone. A resistive microphone (such as a carbon microphone) can be placed in parallel with or replace the resistor, allowing modulation of the tone frequency...
ATV JR TRANSMITTER 440 MHz
This low-power video transmitter is suitable for remote control applications, surveillance, or amateur radio. It employs seven transistors within a crystal oscillator multiplier RF power amplifier chain, along with a high-level video modulator. A supply voltage ranging from 9 to...
transmitter circuit diagram
Clearly indicate on the circuit diagram each type and size of the components. There is a need for assistance in designing a low power FM transmitter circuit, specifically using the BA1404 FM transmitter with a center frequency of 79W and...
Basic RF Oscillator
Create a basic RF oscillator. The circuit is very simple, so complex calculations will be omitted, and component selection will be simplified using calculators. For this example, the target frequency is 7 MHz. The circuit includes a transistor (TR1) on...
