I was wondering if anyone has had any tracking experience with high altitude balloons? I have had a request from a local school in Dubbo for a project for a senior class. There was an article in Amateur Radio magazine a few years ago, does anyone have a copy of it or know which issue it was?<br class="">
<br class="">
any help/ideas is welcomed.<br class="">

Cheers,<br class="">
