The broadcast industry has covered it in great depth and the various Government Agencies have also perfected the two way communications aspect especially narrow band methods. It seems the majority interested in LF do not realise this and think they are a first. Government agencies have used LITTLE and LARGE antennas, high power and low power and know all the answers, a lot of which is in the public domain. It is rumoured that fixed stations on 16 khz were communicationg with submarines under water, at a range of 3700 miles before most of us were born, and some amateurs are struggling to work a few hundred miles into continental europe on 73 and 136 khz. With the advent of 73 and 136 khz to radio amateurs it has enabled them to experiment on an individual basis but do not get frustrated with mathematics and formulae and worried how to go about it, just go to the library get the information, then go home and build it and put up the largest VERTICAL ANTENNA that you can get into your garden. You might then be able to work into the USA or Canada. It is not necessary these days especially with material available on Internet to RE-INVENT the proverbial wheel. de G3KEV
