The HD Radio standard, at least in the US, is encrypted and proprietary, with apparently some rather strong lawyers behind it. So, unless you feel like reverse engineering a few receivers to figure ...

Software-defined radio (SDR) is a flexible and high performance signal processing and radio communication system that employs certain software-based modules instead of traditional hardware-based ...

In the last installment we looked at the ultrasonic hardware used in the development of a software designed ultrasonic data transmission system we are calling the SDU-X. In this second, and last, ...

Want to know how to interface an Arduino with a Radio Control Transmitter? Read on to see how. Signals from the Arduino can be sent to the transmitter as a result of this interface. The arduino signal ...
