The LF Experimenters Handbook has been written to meet the needs of amateurs and experimenters who have an interest in low power radio techniques below 200kHz. Most of the techniques described are targeted at those using the 136kHz band, but they are also of great interest to readers in New Zealand and Australia with the 183kHz band and the Lowfers in the USA on 180kHz.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. All those interested in exploring the new frontier of the LF bands will welcome this invaluable and unique reference, whether they tend to transmitting or are content just to receive. 2000, RSGB,paperback 296 by 210 mm, 146 pages.
