a test of JSON,  with pagination code by Void Singer(modified)

seems to work okay, but could use some beta testers.

Any suggestions welcome :)

- for more than one radio in the same area...., please change the channel number :)

stations in notecard use the format:

Birdsong = http://stardust.wavestreamer.com:8062

Techno = http://81.88.36.42:8010

etc..
