FM carrier current remote speaker system
A high-quality, noise-free wireless FM transmitter and receiver operates over standard power lines. The complete system is designed for high-quality transmission of speech or music and can function from any AC outlet within a one-acre residential area. The frequency response...
AM To FM converter
This circuit can be used to receive AM stations in an FM radio. It is a regenerative circuit that samples AM signals of all frequencies and retransmits them in the FM band or in the TV band.
The described circuit functions...
100W Medium Frequency Transmitter
The 100W4 is a two-tube medium frequency transmitter designed for pre-tuning to three frequencies within the medium frequency band, supporting emissions types A1, A2, and A3. In the A1 configuration, both tubes function as parallel oscillators. For A2 and A3...
SV3 Radio Magnadyne Radio
Most models produced in the 1930s utilize similar circuits, particularly in the RF section, which follows a common LW-MW-SW scheme. Variations among different models primarily stem from the inclusion or exclusion of variable selectivity control, the sophistication of tone controls,...
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...
simple tv audio video transmitter
A simple TV audio-video transmitter circuit can be constructed using this schematic diagram. This circuit allows for the transmission of video signals from a VCR or other devices to a TV without the need for cables. The video signals input...
Remote Control Transmitter Circuit
This transmitter can be utilized for multiple applications. An INS8048L microprocessor produces various codes based on keypad inputs. These codes are modulated onto a 40-kHz carrier frequency. Additionally, Q1 drives infrared LEDs LED1 and LED2.
The transmitter circuit primarily consists of...
Beacon-transmitter
This transmitter is suitable for transmitter hunts, remote key finding, or radio telemetry in model rockets. It can be tuned to the two-meter band or other VHF bands by adjusting capacitor C1 and inductor L1. L1 consists of four turns...
