Cave Radio

Underground communication for cave rescue, cave exploration and more

By Mike Bedford, G4AEE

Most people know that their mobile phones don't work in tunnels and therefore think radio is not a practical underground communication method, with many thinking it impossible. The subject of this book is intriguing because it concerns communicating with cavers, perhaps by transmitting though up to a kilometre of rock.

Whether you're a caver with a need for communication, or a radio amateur or experimenter intent on learning about something new and exciting, this book promises to make fascinating reading. The book is aimed at a wide-ranging audience and you don't have to be a radio amateur to use or develop cave radios. Despite the word 'cave' appearing in the title, you don't have to be a caver to benefit from this book. Indeed, we also expect that electronics enthusiasts or makers could be fascinated by sub-surface communication, as will technically-minded readers who are simply enthralled by an unusual topic.

Moving through the 'why' of cave radio onto the how of 'through earth' communication and 'along-passage' communications, this book moves to ensure your equipment is 'cave proof' and provides opportunities to '˜try it yourself' with radio designs you can build. Not only will you find the LF bands included but VLF, HF and VHF bands too. Cave Radio will guide you in the right direction in choosing and using communication equipment.

Packed with practical information Cave Radio provides an ideal introduction to the art of the possible and even the 'have a go' that it encourages. Lavishly illustrated with inspiring underground pictures, this is for everyone interested in cave rescue and explanation and far beyond.
