Whistlers

Many years ago (1970) I did my final year project at university on whistlers. These are VLF natural emissions. I very nearly did a PhD on whistlers.

My final year university project involved trips to north Wales to record whistlers. These were later analysed in the university labs on kit we designed and made.
