This repository contains helpful resources to receive signals transmitted from an Arduino 433 MHz transmitter with an RTL-SDR receiver using GNU Radio. The project consists of two parts. In the first ...

An AM transmitter for Arduino with four binary inputs to set the pitch of the sound. Pins 2 through 5 may be set to high or low to change the pitch that is being broadcasted. Pin 9 is the ...

As you might expect in 2025 it’s a software defined radio ... it’s similar to the popular T41 Software Defined Transceiver that’s discussed in that ... Arduino code is C++. Report comment.

The arduino signal is mixed with the manual input and the resulting signal is received by the radio-controlled model. Want to know how to interface an Arduino with a Radio Control Transmitter? Read on ...

Arduino Transceiver Shield. July 07, 2015 ... The HamShield is powered by the RDA 1846S radio transceiver IC, which features a fully integrated FM radio transceiver. The chip has an SDR (software ...

Software-defined radios or SDRs have provided a step-change in the way we use radio. From your FM broadcast receiver which very likely now has single-application SDR technology embedded in a chip t… ...

The Arduino-powered AM transmitter was fairly straightforward. As Kainka explained, a transmitting tube was driven hard by the carrier signal (Class C final stage), with its anode voltage modulated by ...

This project mixes the commands sent from the Arduino to the transmitter with the manual input by connecting an Arduino to a Radio Control Transmitter. A trainer cable for the RC transmitter had to be ...

I wanted a different solution and thought of using ultrasonic transducers configured in a software-defined radio (SDR) type framework as the transceiver. While working on the design I realized that it ...
