Written to meet the needs of amateurs
and experimenters who have an interest in low power radio techniques below 200
kHz. Most of the techniques described are targeted at those using the 136 kHz
band, but they are also of great interest to readers in New Zealand and
Australia with the 183 kHz band and the Lowfers in the USA on 180 kHz. The bulk
of the material in the book comprises contributions from experimenters world
wide and covers antennas, propagation, transmitters, special modes and test
equipment, and discusses some applications such as communication with caving
enthusiasts. |
