Eric says that the TMT (TX) coils should all be wound in the same direction with all of the receiving coils (RX) also wound in the same direction, but the opposite direction to that of the transmitting coils. IE the transmitter set of coils are wound clockwise and the receiver set wound counter-clockwise. (Or reversed it does not matter). One set of coils is the mirror image of the other. The primary, secondary and extra coil are all wound in the same direction and for the ‘image coil’ they are all wound opposite.
My spiral coils are modelled on Eric’s original spiral coils. They are two times ten turns for twenty turns total. The length of RG178 co-axial is 25.5 meters. The natural resonant frequency of the coil is measured around ~2080Kcps. With the terminal capacity it brings the Ro down to ~1780Kcps. The maximum input power to the tubes at the moment is around 50 watts, (if that, I usually reduce the power down a bit, but I can increase it up to the full 100 watts). (Two parallel 807 tubes, single ended). With only very short blasts late at night for testing right now. As it is not configured in the CIG mode as yet, there would be some minor transmitting going on. Hams are limited to a maximum of 100 Watts in this country, with some talk of increasing this to 1KW but this has not happened as yet.
The ground plain is just a 1 meter square sheet of aluminium, which isn’t even connected to the earth as yet. (An earth connection is part of the next phase of the project). With only 50watts the TMT already interferes with the touch-lamp inside the house and the TV picture begins to pixelate, (the wife gets mad, but it’s kinda funny to me as she has to deal with a strobing lamp and a weird TV picture). With the telluric output of the coil connected to ground I’m sure the whole TV picture would just disappear like magic, likewise with all of the neighbours TV’s. (It’s tempting to wreak havoc with the neighbours when the football is on, just as they are lining up for a goal, flick the switch and the picture goes out! Hehe, err perhaps not though, as all arrows would certainly point towards me).
I can understand what Eric meant by ‘burning down your neighbour’s house” or the “whole dot-com reality going into melt-down”. With a powerful TMT system sending Longitudinal Telluric Waves into the earth, it would wreak some havoc with the local electronics! So for experimentation with non CIG configurations (I.e. a TMT only) it is wise to stick to lower power systems, like dr Green has done / is doing. You can get some good results and the neighbours won’t be quite so upset. Although if your TMT is in a remote location, this may not be a problem. Using sea water for a medium as you are suggesting may also be a reasonable idea.
I’ll be focusing on the CIG configuration as this should limit the wife’s and neighbours woes and restrict the transmission to a local zone only, so I can operate with the higher levels of power.
Sputins.
