iPhone Software Defined Radio

A software defined radio (SDR) application is available for the Apple iPhone, iPod Touch and iPad.

The iSDR app is a free portable software-defined radio receiver designed for experimenters, shortwave listeners and Amateur Radio operators.

A quadrature sampling detector (QSD) RF front-end device is required to connect between the antenna and the microphone input jack of the iPhone.
