Indeed, the reader should only read this back-up copy if the updated original cannot be found at the original author's site. Hi All, Delta T Antenna Pulser Circuit I discovered this message board recently and thought I would share my thoughts and experiments. See attached picture for circuit details. As you may know, the Delta T Antenna configuration was supposedly used during the Montauk Experiments into time travel. A lot of websites talk about the problem of pulsing the 4 antenna coils sequentially, 90 degrees out-of-phase with each other. Circuit explanation With regard to the circuit, the 555 IC is a square wave oscillator with a variable frequency range of 4 Hz Khz. The output square wave is fed into a 1 -of-10 decoder (although only 4 of the outputs are used). Looking at the waveform graph, you can see what the input waveform looks like. The output pulses (A-D) are sequential and 90 degrees out-of-phase with the preceding pulse. So pulse A happens on the first clock cycle of waveform X, Pulse B happens on the second clock cycle of waveform X, and so on. On the 5 th pulse (out of pin 10 on the 4017 IC), the clock is fed back into the reset pin. So instead of continuing to count to 10, the 4017 IC resets back to 0. The effective output frequency is X/4, or the input frequency divided by 4 -- namely 1hz khz. The 4 output pulses are then fed to a transistor each for amplification purposes, and then into the Delta-T Antenna. Each coil is turned on one at a time. The coils are hand-would Caduceus coils, 15 turns up-and-down on a ferrite core. How to make Caduceus Coils.

2 Experiment I attached these coils to a jogger's headband as close as possible to forming a square. When wearing the headband, I had one coil over my forehead, one each at the side of my head, and one at the back. With power to the circuit, I varied the frequency from beginning-to-end. Results Well I didn't travel in time, experience any OOBEs, visions, or any other psychic experiences. I did feel a buzz throughout my body, and the area between my eyes (brow) seemed to pulse. I was laying in bed at the time and did experience a jolt like I was dropping from a height. I've heard this described as the first stage of an OOBE where you start to leave your body, but suddenly fall back into it as if you had a fright. I also used this whilst sitting on the couch, watching TV. Again, I felt my forehead pulsing and my body had a vibration about it. I felt a bit dizzy when turning my head and trying to focus on a new object. Future Experiments Something is definitely happening with this circuit. I want to try different frequencies and increase the power output. When using it in the couch that time, I could feel like something was about to happen. Like I was charged with energy, but not enough. I think it needs more power. I need some specific frequencies to experiment with, such as the Schumann Resonance (7.83 Hz).

3 Suggestions Constructive criticism is welcome, along with suggested frequencies to experiment with, power levels, circuit modifications, etc... Alakazam Hey Alakazam Taking some lessons from Quantum Mechanics and string theory, apparently our reality resonates at ~ 450 MHz. I have attached a pic of a VCO used in RF that should generate your MHz timing signal. You might need to use some RC circuits to retard the 'reference' wave or 'zero point' by 90 degrees, 180, and send each retarded signal to each coil. But before you up the frequency, try to focus your mind when using your current device. Like anything else, Einstein focused his mind on physics and look what he came up with. Try to go to sleep with a lot of stuff on your mind and you won't get far. Try to clear your mind first, then focus, and block out anything irrelevant that pops in your head. I like thinking of a white piece of paper with nothing on it. Still on my drawing board is to use each pulse to fire a high voltage capacitor (preferably flash caps) at 0, 90, 180, and 270, all charged from a voltage tripler (120 x 3). They should have a profound effect as to the strength of the fields u want to generate. Last edited by smartbomb : at 10:09 PM. P.S. I found the 'apparent' frequency. It's 435 MHz. As none of this can be proved or disproved, good luck and god-speed. Dear all, I am new to the board, I was searching for further information regarding the "Montauk Chair" and came across this site. I would just like to post my thoughts regarding the Delta-T antenna. There is a common misconception going around the Internet about the Delta-T antenna having 4 coils as shown in the diagram on this page. Preston Nichols says clearly in the 1 st st and 2 nd nd books and shows you in the video where he demonstrates the recovered equipment from the base that the Antenna is made from 3 coils. Two are made as diamond shapes and fixed together and 90, so you get the frame of a large 3D diamond. Then the 3 rd rd coils goes around the middle so it looks like 2 pyramids base-to-base.

4 He says the coils are PLACED 90 degrees to each other as well as PHASED/PULSED at 90 degrees. How can you place 4 coils all at 90 degrees to each other? In 3D space, this is impossible! The top and bottom coils are 180 degrees out and so are the left and right ones (with respect to each other). I have built one of these. But without building a flip-flop circuit in 90 degree mode, I simply created a audio track of 1-Hz using my PC. I then opened the.wav file in "goldwave" and shifted the left and right audio channels by 250 milliseconds, then saved it and burnt it to CD. 250 milliseconds at 1-Hz is obviously a 90 degree phase shift. I put the CD in my hi-fi, then fed the out put through an amplifier and in to the coils of the antenna. Placing a compass inside the coil structure, you will see the compass spin as the magnetic field is spinning. However, to do this at 435Mhz will require a tuned RF phase shift network. A lot harder to create -- no 555 timers or 4017/4013 used here! Has anyone researched into the Montauk Chair? It seems silly building the antenna if you cannot pickup a signal to transmit out through it? Best Regards, Dave. ctglabs Hello Dave, Thanks for the reply! I have been trying so hard to find a proper schematic for this Delta-T configuration of the antenna. I assumed the 4 coils would go onto the 4 sides where the 2 pyramids meet with a respective phase shift. At this point, I've only been able to find the picture of the diamond-shaped antenna. Do you have a pic that I can use to construct my own antenna from? I am having difficulty trying to determine how to make each tetrahedron in the antenna with an impedance so that I can feed my MHZ signal into it. I have access to an HP frequency generator for this frequency and also a frequency spectrum analyzer to view harmonics generated in the immediate area. I'm just stumped on construction of this bad boy. Sb Any insight would be greatly appreciated. Hi Alakazaam, You might have felt scalar wave fields. Be careful with experimenting with these waves as they can produce dangerous effects on the body. Scalar electromagnetic waves are a known byproduct of Delta-T type configurations, and they are very powerful waves. Many researchers have reported this phenomenon. You might want to read to find out more about the possible dangers of being exposed to scalar waves. Best wishes. backto1992 Junior Member
