Electroluminescent Receiver Kit Includes

Before starting on the receiver side of the Chatterbox, a final review of the transmitter is necessary. The Chatterbox transmitter is constructed separately, as many builders may wish to use it alongside an existing receiver operating at 1.8 MHz....

Assistance is required regarding the circuits provided below. The focus is on an ultrasonic receiver circuit that utilizes two ultrasonic components. The ultrasonic receiver circuit is designed to detect ultrasonic waves, typically in the frequency range of 20 kHz to...

A low-cost continuous wave (CW) superheterodyne receiver operates with a 4.00 MHz intermediate frequency. While there is no automatic gain control (AGC) or RF gain control, the receiver demonstrates good large signal handling capabilities. The design incorporates six bipolar...

Figure 1 shows the block diagram of a direct conversion RF receiver—the receiver demodulates an RF carrier directly into a baseband signal without an intermediate frequency down-conversion (a zero IF receiver). The antenna, shared by both the transmitter and...

This project originates from the past and has demonstrated significant success. It serves as the foundation for an 8-channel proportional R/C (AM) and 145MHz FM chat box. The receiver design is straightforward and includes a single transistor mixer followed...

The TDA7088T can be used in mono portable and pocket radios. This is a bipolar integrated circuit. Here is one of the application circuit diagrams. The TDA7088T is a versatile bipolar integrated circuit designed specifically for mono FM radio applications,...
