Enter CHIRP. CHIRP is a cross-platform, cross-radio programming tool specifically focusing on ICOM D-STAR radios, although there seems to be nothing preventing you from using it with non-D-STAR rigs.

Chirp, which lets you transfer data between devices using nothing but audio clips, has announced it's opening its platform to developers as it looks to increase the uptake.

Smartwatches are all well and good, but their tiny screens mean they're not the easiest device to operate. If only someone could sort out some tech to recognize 3D gestures.

To begin with, Chirp works much like any other social media service: you use a free app to upload whatever you want to share – for example, a picture – to a web server.
