If you have decent internet access, there is a one hour long, weekly "radio" show on the BBC Scotland website:

http://www.bbc.co.uk/scotland/radioscotland/programmes/pipeline/

It is available to listen to, any day, any hour, but you do have to listen to it live on the net, no downloading.

It's dedicated solely to piping (hence the name.. PIPEline).  You will hear some of the worlds best solo & bands playing, as well as current news and announcements from the world of piping.

Give it a listen..
