You can listen in to SW radio over the Internet using a free download application called SDR-radio by accessing a network of connected SDR radios.

I also use a Funcube Pro+ USB dongle radio on a notebook PC as SDR-radio Ver 2.0 is now compatible with the Funcube.

These devices are all part of an off grid BOB SIGINT/Communications bag.
