+CWS is a capacitive wave system designed to provide a very pure, ultra-low power signal that produces unexplained bioeffects in living systems.
-Industry has very effectively distracted science away from electrosmog, and towards cancer and cellphones themselves. That has to change. But change is difficult when the EMF meters for retail sale, except for our Cormet ED85EXS, bottom out above the -60dBm area of interest - meaning that dirty environments look clean - and while people suffering from EHS cannot control their environment, and therefore cannot demonstrate cause and effect. ”
-“People have asked me why I don't get paranoid about "dangers from cellphones." The reason is they really do not put out as dangerous a level of radiation as the electrosmog, or as the major sources of radiation in a home.
+The Capacitive Wave System (CWS) was developed by the Autoimmunity Research Foundation in 2014 as a research device for experimental use by members of our research site struggling with the symptoms of chronic disease.
-Alasdair Phillips explains that a modern cellphone only uses the power it needs, and no more. This is why I said in the final slide of my St Petersburg presentation that EHS and Cellphones can co-exist, as long as we lower the levels of electrosmog using something like Google's "Project Loon"

-<blockquote>KT - over on SchwannSongs posted the following links this morning to material of great interest to us. It is translations from 1977 of USSR studies which documented harm to humans from electromagnetic exposure. Here are two that I found particularly interesting. especially the high rate of Cardiac problems...
+A new research initiative of the Autoimmunity Research Foundation is hoped to be complementary to the protocol for those with more difficult neurological distress.

-<blockquote>FM, shortwave, and TV frequencies are lower than cell phones and WiFi, and therefore carry less energy per photon. But the photon flux is much higher. Typical FM and TV towers radiate at 50,000 Watts, rather than your cellphone's 5Watts. Thus the total energy in the microwave photon flux from SW, FM and TV may be just as high as with microwave signals, and it is this total flux which affects our molecular biology.
-</blockquote>
+This research question was asked with the understanding that it is not generally considered possible that the 25 nanowatt power (-100dBm at 1 meter) produced by these systems would have any effect at all on the biological function of the human body.

-===== How advanced emf sensitivity is diagnosed =====
+The general observation is that healthy people do not respond to exposure to the Capacitive Wave Systems in the same way that those who have chronic symptoms of illness. Healthy persons will report it "did nothing" when they were exposed to it.
-Current Concepts in Diagnosis and Management of
+Responses by our members, who by definition are facing some type of chronic symptoms, varied greatly. Some individuals had an immediate and negative response. Others found it had a subtle, but persisting effect in improving idiopathic symptoms that had been difficult to resolve using standard approaches.
-         Electromagnetic Hypersensitivity (EHS)
-           by Dr. Erica Mallery-Blythe, 7 March 2014
-at BSEM Electromagnetic Radiation & Health Conference, London

+Unexpected Discovery
-Note at 2:50min the description of Tesla's EHS condition...
+An unexpected discovery came with the observation that those with a high level of Electrosmog in their home or work environments were more likely to have a negative effect from exposure to the CWS.
-==== American Disabilities Act ====
+Some found ways to reduce the EMF power levels below -55dBm and reported changes in their symptom levels as they did. Research into optimal methods of measuring and mitigating Electrosmog effects is ongoing.
-Recognition of the Electromagnetic Sensitivity as a Disability Under the ADA
+Those members that have not yet addressed the high levels of Electrosmog in their environments, especially the environment during their sleep hours, are most often the ones that also report an inability to tolerate exposure to the CWS.
-The Architectural and Transportation Barriers Compliance Board (Access Board) is the Federal agency devoted to the accessibility for people with disabilities. The Access Board is responsible for developing and maintaining accessibility guidelines to ensure that newly constructed and altered buildings and facilities covered by the Americans with Disabilities Act and the Architectural Barriers Act are accessible to and usable by people with disabilities.
-In November 1999, the Access Board issued a proposed rule to revise and update its accessibility guidelines. During the public comment period on the proposed rule, the Access Board received approximately 600 comments from individuals with multiple chemical sensitivities (MCS) and electromagnetic sensitivities (EMS).
+==== Without Measurements You Don't Know ====
+ [[http://www.ehs-mcs.org/visuels/1390928073_18_1_Zoom.jpg|device frequencies]]
-The Board has taken the commentary very seriously and acted upon it. As stated in the Background for its Final Rule Americans with Disabilities Act (ADA) Accessibility Guidelines for Buildings and Facilities; Recreation Facilities that was published in September 2002:
+Measuring your environment is the only way to accurately identify the sources of EMF so that you can begin the process of learning what is affecting you and how you respond to the many different types of sources of radio frequency radiation (RFR) commonly present around us today.
-" The Board recognizes that multiple chemical sensitivities and electromagnetic sensitivities may be considered disabilities under the ADA if they so severely impair the neurological, respiratory or other functions of an individual that it substantially limits one or more of the individual’s major life activities. The Board plans to closely examine the needs of this population, and undertake activities that address accessibility issues for these individuals."
-Following its recognition of electro sensitivity and its declaration of commitment to attend to the needs of the electromagnetic sensitive, the Access Board contracted the National Institute of Building Sciences (NIBS) to examine how to accommodate the needs of the electro sensitive in federally funded buildings.
-In 2005 the NIBS issued a report.
+Professor Marshall has engineered a device he calls the Sniffer, now in Beta testing by ARF volunteers
-The link for the report:
+<blockquote>Low sensitivity setting silent until -47dBm then builds warning from there.
-[[http://web.archive.org/web/20060714175343/ieq.nibs.org/ieq_project.pdf|NIBS report]]
+High sensitivity silent until -57dBm, building from there. High sensitivity also has advanced pulse detection to catch fast single pulses (eg an airport or ship radar scanner).
-From Report (page 11):
+The red "Evacuate" light flashes starting at -17dBm, a 1000:1 range (30dB) in Low sensitivity.
-"Electromagnetic Fields
-For people who are electromagnetically sensitive, the presence of cell phones and towers, portable telephones, computers, fluorescent lighting, unshielded transformers and wiring, battery re-chargers, wireless devices, security and scanning equipment, microwave ovens, electric ranges and numerous other electrical appliances can make a building inaccessible.
+The unit should remain silent. If the red light says "Evacuate" then it really means "Evacuate." Even healthy people will have dulled brains at those levels.
-The National Institute for Occupational Safety and Health (NIOSH) notes that scientific studies have raised questions about the possible health effects of EMF’s.

+==== Don't Guess ====
+When we start to guess at what could be affecting us, our errors can lead us into wasted effort and loss of credibility. It's critically important that we fully evaluate every source of RFR we are exposed to so that we can approach mitigation effectively and intelligently.
+===== What You Are Looking For & How Meters Help =====
+Invisible waves require special tools to measure power and frequencies so you can find out what is in your environment and then take sensible steps to mitigate the problem sources.

+==== Antenna ====
+Antennas are needed to pick up signals for the meters
+The antennas supplied for use with both the Cornet and the RF Explorer are not sufficient: more accuracy is necessary to measure the emf which affects our cells
+=== Handling & Usage Tips ===
+  * [[home:special:effects_of_emf:measuring:meters:using|Guidance for using measuring devices]]
+=== Where to Buy ===
+Amazon and Ebay may supply some of your needs
+  * [[home:special:effects_of_emf:measuring:meters:buying|Guidance for buying measuring devices]]
+=== How it Works ===
+<blockquote>The directional antenna covers 850MHz to 6GHz, the microwave region. That includes cell phones, DECT phones, WiFi and smart-meters but not FM, TV, AM or shortwave radio. The whip picks these up, especially when extended. By collapsing the whip down to just one section, you limit the sensitivity of the whip to (approx) 900MHz to 6GHz, or the same as the directional log-periodic. But the directional antenna gives an extra 7dB of amplification when it is pointed at the source of the radiation. You can switch the sound on the Cornet and this also helps you distinguish what the signals are (FM stations are totally silent, for example).
+Trevor Marshall, PhD</blockquote>
+<blockquote>a -50dBm signal is 316 times lower in amplitude than a -25dBm signal, which most definitely is a big improvement! :)
+Trevor Marshall, PhD</blockquote>
+<blockquote>As a scientist I want to be able to measure down to 'absolute zero' which is effectively 'below 390 degrees Kelvin'. I am still at 690K even with the preamplifier :X You don't need to go that low. As Amelie found in her canyon, once you get so the Cornet audio is silent at -65dB with the whip, you are getting very close to where you need to be. I am building the preamplifiers so that I can measure a little lower with the Cornet. Obviously the RFexplorer, with its smaller noise bandwidth, can go much lower, down to about -110dBm with narrow-band signal sources.
+Trevor Marshall, PhD</blockquote>
+==== CORNET Meter ====
+Basic usage tips
+<blockquote>5 metres from a microwave the signal is still too strong. Don't put your Cornet near the microwave, but use it to measure the signal at the other end of the house. I think you will be surprised how powerful those ovens are.</blockquote>
+=== What You Can Learn From Readings ===
+The CORNET meter is very good at providing a very accurate single number for the current peak power over the entire spectrum from 1Hz to 8GHz. It also provides a small window displaying a moving history of the most recent peak power readings.
+While you don't know the frequency of the source of this peak power and you also don't know what other sources may be present at near the same or lower power levels, it gives you an immediate assessment of your environment's level of radio frequency radiation (RFR).
+=== What You Can Learn By Adjusting the Antenna Length ===
+By putting the adjustable antenna on the CORNET meter and taking measurements at the various lengths, a general sense of the range of frequencies present in your environment.
+=== What You Can Learn From Audio Output ===
+While the CORNET meter only provides a single number for the current peak power over the entire spectrum from 1Hz to 8GHz, it has another method of quantifying the types of signals in your environment - sound.  Different types of signals sound differently on the CORNET:
+	• Television Broadcast Antennas - constant lower-pitched buzz, similar to 60Hz
+	• Cell Tower Antennas - constant higher pitched whine
+	• DECT Phones - continuous clicking
+	• WiFi Routers - non-continuous clicks
+	• 4G Modems and Antennas - pulsed sputter or "raspberry" (often at extremely high power levels)
+=== Limitations ===
+The CORNET does not catch the fast pulses of 4G. The Foundation's sniffer does.

+==== RF Explorer ====
+The RF Explorer is a spectrum analyzer.
+<blockquote>
+This is the device which works best for portable spectrum analysis:
+[[http://www.amazon.com/dp/B00GM72CGU|RF Explorer and Handheld Spectrum Analyzer]]
+You need this 3G combo version, with the 15-2700 MHz wideband section, as well as the 220-960 that works a little better on Smart Meter radiation.
+Here is the website of the designer: [[http://micro.arocholl.com/|RF Explorer]]
+This is an open-source project. Both the firmware and the interfaces to your Desktop software are open-source community based projects. The hardware is built by Seeed studio in China.
+There have been rumors that a new version with a 6GHz upper frequency limit will be released within a few months, but 2700MHz covers all the cell-phone 4G allocations
+//Prof Trevor Marshall  Dec 2nd, 2014 //</blockquote>
+ Use FAST filter and PEAK HOLD on an RF explorer to explore digital signals.
+<blockquote>
+Here is where I usually set up my Rfexplorer when surveying a new site:
+G/4G frequencies: Whip antenna fully collapsed
+Center Freq: 2200
+Freq Span: 600
+Module 15-2700
+Calculator: Max Hold
+Top dBm: -30
+Bottom dBm: -100
+Iterations: 005
+Offset:0
+Units: dBm
+Draw Mode: Vectors
+Marker: Peak
+DSP: Fast
+This setup covers 1900MHz to 2500MHz and shows you DECT phones at far left, WiFi at far right, with the main 3G/4G bands in between. For looking at DECT in particular I use Center Freq:1925 Span:10. For just WiFi I use 2450 span 100. There are also some less active 2G/3G/4G bands between 700MHz and 1000Mhz, and some 4G between 2500 and 2700Mhz.
+//Trevor Marshall, PhD//</blockquote>
+Professor Marshall, .. is happy with using this antenna with the RF Explorer as well:
+    Superbat 5dbi 700-2600Mhz 4G LTE Omni Directional Antenna
+<blockquote>The small (WiFi) antenna that came with the RF Explorer was no use at all, and the extendable antenna has a coil in its base which stops it working properly at high frequencies. The 'blade' antenna I suggested will cover all the cell-phone and WiFi bands reliably, and the whip covers from 110MHz (extended) to 2GHz (when collapsed).</blockquote>
+The antennas which came with the RFexplorer will give you a good idea what the signal strengths are, but when you want accurate measurements you will need to have a reasonably decent antenna.

-<blockquote>//mvanwink //
+There is an important key to charging the device:
-The RF is doing damage whether we see it or not, or whether our friends or family acknowledge it. My cousin who lives in the country in a small town got cancer of the sinus on the side of the head he uses his cell phone. My mom had an acoustic neuroma which at least in rats could only be initiated by exposure to RF. And the story goes on.
+... the power switch must be ON when it's plugged in, or else it isn't charging ...
-This is modern life. We have to adapt. What we have learned here will allow us to be healthy in what has become a world hostile to life.
+=== What You Can Learn From Readings ===
-As for myself, because of shielding I no longer have muscle knots except when I get a long term (week long) dose of -30 dBm or stronger RF - that was with protection (not the newest garment which are 10 dB better). So, it looks like we can be more normal than a 'normal' person, but it requires protection.
+<blockquote>Using the RF Explorer, I was able to speculate that most of my highest signals are in the 100-500MHz bands. Over the hill from my home there are all of the types of antennas for the signals described below. (Except for the airport radars, those are over a mile away, but still awfully close)
+From: Very high frequency (VHF) and Super high frequency (SHF)
+  * Common uses for Very high frequency (VHF) are FM radio broadcasting, television broadcasting, two way land mobile radio systems (emergency, business, private use and military), long range data communication up to several tens of kilometres with radio modems, amateur radio, and marine communications.
+  * Air traffic control communications and air navigation systems (e.g. VOR, DME & ILS) work at distances of 100 kilometres or more to aircraft at cruising altitude.
-</blockquote>
+  * VHF was used for analog television stations in the US, and continues to be used for digital television.
+  * Super high frequency (SHF) is the ITU designation for radio frequencies (RF) in the range between 3 GHz and 30 GHz. This band of frequencies is also known as the centimetre band or centimetre wave as the wavelengths range from one to ten centimetres.
+  * These frequencies fall within the microwave band, so radio waves with these frequencies are called microwaves. The small wavelength of microwaves allows them to be directed in narrow beams by aperture antennas such as parabolic dishes, so they are used for point-to-point communication and data links[1] and for radar.
+  * This frequency range is used for most radar transmitters, microwave ovens, wireless LANs, cell phones, satellite communication, microwave radio relay links, and numerous short range terrestrial data links.
+I suspect that the building materials of my walls (stucco on wire mesh) block some waves. Especially those in the microwave (SHF) range.

+=== When to Buy v.s. Sharing ===
+- The following meter is so inexpensive it may be the choice for those who have limited means but no wish to share
+<blockquote>I think I have been too harsh on the DT-1130 "Electromagnetic Radiation Detector"
+When I took out the switching power bricks powering all my computer equipment (and routers, etc) the DT-1130 now stops beeping whenever I place it towards my computer screen and laptop. It did sense the change to a cleaner environment. It used to beep anywhere within a foot of either device...
+But it still beeps whenever near power cords (even though they only show 30GS units).
+When it was beeping near my routers - that's OK, I thought, they have computer chips in them.
+But this morning I installed shielded ethernet cables. Now it no longer beeps on the routers. Hmmm...
+I think the problem I had with the DT-1130 initially was that my environment was so noisy that it beeped at everything (which it did). So the meter was not much use for diagnosis of individual devices. Bat as I eliminated each source of trouble, the DT-1130 has gradually stopped complaining about them... Hmmm... Not bad for $10, I suppose. But it is going to make a lot of noise until you get your environment reasonably clean...
