Ground Wave or Sky Wave Luke Skywalker?

How to make a Personal Jamming Device (PJD):

The VLF (Very Low Frequency) band has been used since World War 2 for submarine communications, because the long wavelength propagates thousands of kilometres, along the surface of the Earth, and can be received hundreds of feet below sea water. The transmitting antenna has to be large, normally a grounded vertical monopole over a thousand feet high. For example, the Harold Holt communications station near Exmouth in Western Australia uses over a MegaWatt of power to cover the Pacific and Indian Oceans. In fact for the VLF band (10 KHz to 30 KHz) there is a standing wave between the Ionosphere and the surface of the Earth so that it is like the Short Wave Band (1 MHz to 30 MHz), using both the sky wave and the ground wave to propagate over long distances. The only place German U-boats could not receive VLF signals was in the Fjords of Norway because there, the granite rock contains iron ore and provides natural shielding. Very Low Frequencies are also used for surveillance bugs because, unlike satellite communications, the signals penetrate below the ground into railway tunnels and the basements of buildings. The RF implants or bugs are microscopic nuclear powered devices that last for years. It is difficult to jam these signals because such a large transmitter antenna is required but the receiver antenna is comparatively small, consisting of a coil with hundreds of windings around a magnetic core as found in Medium Wave radios. In fact the magnetic field of the long wavelength radiation is received rather than the electric field so that the signals even penetrate Faraday enclosures completely shielded by metal.

This article describes a simple jamming device using easily obtainable components and a ferrite core antenna with a coil of a thousand windings. It uses a reverse biased Zener diode, in avalanche mode, that generates broadband noise. The output power, after amplification by a Darlington pair of transistors and operational amplifiers, is milliWatts blanketing the Long Wave Band (from 1 Hertz up to 500 KiloHertz) with RF noise. The antenna is like a 'magic wand' that when held close to a person's head, or worn around the neck, effectively jams all low frequency signals within centimetres without affecting anybody else. The maximum antenna gain is along the axis of the magnetic rod. Figure 1 shows a picture of the completed device.


Figure 1: A photograph of the Personal Jamming Device.



Figure 2 is a schematic diagram showing how to build the Personal Jamming Device using simple components that can be easily obtained from Electronics stores like Jaycar (any 6.8 Volt Zener diode will do). Shielded coaxial cable is not needed to connect the antenna because the wavelength is kilometres and the length of the wires connecting to the ground and noise output is much shorter. The electrolytic capacitors are polarized so make sure you connect them the right way. If connected in reverse, electrolytic capacitors can explode. Use a prototyping board to mount the components and a ten AA battery pack as a power supply. If more output power is required to completely jam the long wave signals, then try using a switch to increase the gain of the LM386 amplifier chip from 26 dB to 46 dB, with a 10 microFarad Electrolytic capacitor between pins 1 and 8 (as shown in Figure 2), although this will drain more power from the batteries. Careful to adjust the 10 KiloOhm potentiometer leading into the LM380N 2.5 Watt audio amplifier chip so that it does not over heat.

NOTE: The wavelength at 10 KiloHertz in the VLF band is 30 kilometres, so to jam the signals effectively you need at least 300 hundred metres of wire coiled around a magnetic core. My latest PJD has an antenna with 400 metres of light duty wire, with several thousand windings around a two ferrite rods taped together length wise . Plus I made a 4:1 voltage Balun (that is a 16:1 impedance transformer) using a FT-290-43 magnetic toroid, with 50 primary turns and 200 secondary windings. This helps match the antenna to the output impedance of the amplifier, to radiate more power from such a short antenna. You can use the same magnetic rod that was used for the antenna to make a Balun, instead of a circular toroid although you might need to experiment with the number of primary and secondary windings depending on the type of ferrite material (magnetic permeability). I also noticed that the PJD works better at night time because the surface conductivity of land across central Australia decreases with temperature on cold winter nights, resulting in lower signal strength for the ground wave. Furthermore, at night time the F layer in the Ionosphere moves upwards from 200 km to 300 km above the Earth and the E layer at 100 km altitude is only there during daylight hours. So the standing wave between the Ionosphere and the surface of the Earth only occurs during daylight hours and the skywave does not propagate at night time for VLF, although the signals can still be received via the ground wave but with a lower Signal to Noise Ratio. Sweet dreams!

Not much has been published about VLF for anything other than low baud rate submarine communications, because there is not much bandwidth below 100 KiloHertz. However, the low frequency surveillance bugs use frequency hopping or spread spectrum techniques to achieve high data rates, even though it may be hard to see the signals on a spectrum analyzer. It is possible to build a 'silent room' for private meetings that not only acts as a Faraday shield for higher frequencies but also acts as a magnetic shield for very low frequencies, effectively blocking all RF signals from entering or leaving the room. A Faraday enclosure is not effective for very low frequency signals. For low frequency signals (< 100 KiloHertz) a magnetic shield is used instead, with multiple layers of nickel or ferrite alloy that has a high magnetic permeability. A quick way of doing this would be to spray nickel paint to completely cover the walls, floor, windows and door of a room. Alternatively mix iron powder with anti-rust paint containing Zinc and apply multiple layers for adequate shielding. You could build a magnetically shielded room in a place like the Blue Mountains where there is iron ore in the rocks that provide natural shielding from VLF signals, like the Fjords of Norway.


Figure 3: Ground wave or sky wave ?


If you want to jam VLF in a whole room, then you can run the output from the schematic diagram in Figure 2 through a commercial car amplifier, except without the 2.5 Watt LM380 chip on the output to avoid overdriving the car amp. I used a Response Precision 2 x 150WRMS car amplifier (model AA0452) available from Jaycar for about $200) with the 2 stereo output channels “bridged” into a single speaker or in this case a VLF antenna. Thick wire (heavy duty 18 gauge) must be used for the Balun and antenna reels because the car amplifier runs off 12 Volts with a DC of 15 Amps and the bridged output of the car amp can be more than 300 Watts! The number of turns for a Balun can be calculated accurately depending on the radio frequency and the magnetic permeability of the cores which are readily available from www.amidoncorp.com in America. For High Frequency Baluns a circular toroid is used as shown in Figure 4 as follows.




Figure 4: HF 200 Ohm Balun on the left and VLF 800 Ohm Balun on the right.


Alternatively for VLF Baluns ordinary ferrite rods from a local electronics store are just as effective, by experimenting with the number of primary and secondary turns. The following Balun consists of eight 10cm ferrite rods taped together with 200 secondary inner turns and 50 outer primary windings to make a 4:1 voltage transformer for 16:1 impedance matching. This is because the output impedance of the audio amplifier is only 4 Ohms for an audio speaker and the impedance of the magnetic coil antenna is much higher.





Figure 5: VLF Balun constructed of eight ferrite rods taped together surrounded by 200 inner secondary turns plus 50 outer primary windings with heavy duty 16 gauge wire for a 16:1 impedance transformation, to match the output of the car amplifier to the high impedance magnetic coil antenna.


The VLF antenna consists of two 100 metre reels of heavy duty wire with ferrite rods inserted along the axis of the reels to improve the inductance at low frequencies. A large fan can be seen on top of the car amplifier in Figure 6 to keep it cool for continuous operation, amplifying broad band noise. Normally this amplifier runs off a car battery with plenty of cold cranking amps, but I used a 20 Amp 12 Volt DC regulated power supply from Jaycar plugged into the 240 Volt AC mains electricity. In fact if you plugged this amplifier into the cigar socket on the dash board of some cars it would blow the 15 Amp fuse in the fuse box. Use an RCA splitter or double adaptor to connect the noise source to both stereo input channels. Don't forget to switch on the High Pass Filter provided with the Response Precision AA0452 amplifier and set it to the top frequency because the Balun only works above 500 Hertz. You can adjust the gain of the amplifier with the Sensitivity and Volume controls so it does not get too hot... I used the minimum settings with the noise from the 1 Watt LM386 audio amplifier chip.



Figure 6: Response Precision AA0452 car amplifier connected to the Balun and two coils of wire with ferrite rods along the axis of the reels as a VLF antenna. Note the large fan on top of the car amplifier to keep it cool.


Figure 7: WinRadio showing the audio spectrum at 15 KHz with broad band noise from the amplifier.



Another method for shielding against VLF signals, that can be used in addition to a portable long wave jamming device like the PJD, is a steel helmet with multiple layers of anti-rust Zinc paint mixed with Iron or Nickel powder. The example in Figure 8 is a replica of an Ancient Greek Corinthian helmet that is made out of Steel rather than Bronze or Brass. This also provides nearly complete electric shielding from microwaves as well as partial magnetic shielding from long wave signals.



Figure 8: A steel replica of an Ancient Greek Corinthian helmet with multiple layers of anti-rust Zinc paint mixed with Iron and Nickel powder. The electric field of long distance VLF signals is vertically polarised but the magnetic field is at right angles and horizontally polarised. Therefore the magnetic field cannot enter through the neck of the helmet when in an upright position, but may get in through the visor.

Seems like someone not only forgot to do any research using real, peer reviewed sources rather than conspiracy websites, but also neglected to take their dose of lithium today.

But please explain further how, if the transmit antennas (quite rightly) must be massive, these 'surveilance devices' manage to send back any data on the target? Ive used such devices myself, their called RFID tags. Not very covert im afraid, i have to be within a foot of the target with a big coil of wire.

If you really want to come to the attention of the spying agencies, start buying all the mohn-metal and nickel shielding you'd need to make your 'silent room', and digging your evil mastermind lair under the blue mountains...

DANGER! DANGER!

DO NOT use Ladder Line for your antennas! Squirrels may try climbing on it, slip off, fall and injure themselves.

If you are a squirrel who has injured himself on ladder line, please contact Attorney Filbert Nutjob for a free consultation.

There is no fee if we do not collect nuts for you.

Would it be OK for the squirrels if I use window line instead of ladder line? Window line is much more readily available.

In early 70's the U.S. Navy keyed the Anthorn VLF from London, I know, I put the tapes on the TD and ran the crypto.

Why would I want to jam vlf? That question doesn't appear in this article. Oh! paranoia, I get it.

the comment about using ASL was good but I have attended a meeting where the subject matter was so sensitive that other than casual conversations all pertinent discussions was by etch-a-sketch, and this was inside a secure room. I thought it a bit over the top, but being low man on the food chain felt it was best to just put my comments on the etch-a-sketch like everyone else.

Give the guy a break. I'm more interested in the projects than the rag chews anyway. He's experimenting with radio...something that hams have a long history doing. It's easy to flip out a nut job comment, but he's obviously spent time and energy here. Through such experiments, new technologies are discovered, skills honed. VLF is an area that we don't hear much about. I found it all very interesting.

Well, that was fun.

All kidding aside... VLF has been being used for weapons that do not kill, but rather place perpetrators in a temporary coma for "peaceful apprehension" purposes.

More importantly, this type of experimentation requires great caution. A person could end up shutting down their own vital systems if resonating particular frequencies.

Best advise read yet is pencil and paper.

My compliments to the OP foran entertaining and thought provoking article. Thoughts of...

Right-hand polarization is essential for the whole mechanism to function as designed. Failure to meet this critical item will result in a logarithmically increasing cascade failure, ending with collapse of the containment field, and subsequent total destruction of all matter within a 1 light-year radius of ground zero.

Personally, I don't understand all of the shock over this post. Have any of you been to a Hamfest and taken a gander at the attendees? It's "whack-job central"! I'm not saying all of them, mind you. But there is usually in attendance a very high concentration of guys that live in their parent's basements and only come out for the "Hamfest". The radio hobby (both Ham and CB) seems to attract a whole lot of people with socialization defects. These people have trouble interacting with other human beings because of their fruit cake behavior and radio is their only means of having at least a modicum of social interaction. This kind of stuff is more common than you realize in the world of radio.

Funny people mention pith helmets. In 1961 the US Army on Okinawa issued tropical uniforms. This consisted of a pith helmet(NVA style) with officer or enlisted insignia, short sleeve shirt, shorts (khaki of course) knee socks, and low quarter shoes. This get up lasted until our first formal inspection wearing it. Nobody had the knees to do any of it justice. It was so ridiculous in appearance that they came back and had ll of us turn them back in. Now if we had just had those neat pith helmets from Zulu, and of course those red uniforms to go with them.

In the VK the foundation license is the ham license that comes in the cornflakes box.

According to the license conditions for those who obtain this license, they are not supposed to build any transmitting equipment. He is in breach of his license conditions. Its ok for him to buy a commercial jamming device but not build one!

The foundation license in VK has been a total disaster for the ham radio hobby. The ham bands have turned into the equivalent of the CB band in a very short time. These CB hams have been engaging in jamming of police communications, jamming of hams, death threats, music playing and general bad normal CB behavior. From all accounts all the retired ex CB'ers have got a new foundation license because it seems they have more victims to play with and jam.

If you live in country that does not have a foundation or similar kind of license system, from what I have heard is that you should pray that you dont get this type of license system in your country. There are many reports of all these 10 watt stations running illegal power as high as 5kw output in VK land when the average extra class ham can only run 400 watts.

I suppose thats why they gave these operators the F suffix, F as in F...wits

But Captain, nobody has addressed the dangers of the loss of antimatter containment, resulting in the reverse oscillation of the di-lithium crystals which naturally would result in a neutron based singularity!

I don't know about RF helmets but at the '72 Dayton Hamvention there was a publisher of a well known Ham publication running around with a 2 meter rig in a fire helmet. Thought I saw a couple of guys in white jackets chasing him with a net.

The best thing about this jammer is that it would penetrate the tin foil beanies with its magnetic wave. :)

Is that noise you hear in one ear or both ears (or between your ears)?
