This $40 radio communicates on the 136-174 MHz and 400-480 MHz bands. It uses a one-time programmable microcontroller and the RDA1846 transceiver.

transceiver_control.py: Program to transmit FT8 or FT4 messages using the Arduino microcontroller. It has a simple menu to generate messages and uses weakmon encoder to generate the channel symbols.

ADX - is abbreviation for Arduino Digital Xceiver. ADX is a mono band (actually quad band) digital modes optimized HF transceiver that can cover four pre-programmed bands one band at a time by ...

To this end, engineers at Columbia University (CU) claim to have created a world-first, full-duplex radio transceiver, all on one miniature integrated circuit.

[Mark VandeWettering] was experimenting with a simple transmitting circuit and an Arduino. The circuit in the project was designed by [Steve Weber] to broadcast temperature and telemetry data using… ...

Abstract: In this paper we present design results related to integrated circuits for low power and high frequency transceiver implementations. We first consider the traditional LC voltage-controlled ...

Arduino enthusiasts looking for a new project to keep them busy over the weekend may be interested in a new Arduino FM Radio Project, which uses an ATmega328-based board to communicate with a ...

In this paper we present an 8Gbps CMOS amplitude-shift-keying (ASK) modulator in the transmitter and a 19.2mW 2Gbps CMOS pulse receiver circuits for high-speed and low-power 60GHz millimeter-wave ...
