There is a considerable amount of confusion regarding the new Smart Meter also called AMI (Advanced Meter Infrastructure). There are two different emissions within a Smart Meter. One is the Microwave Radio Frequency emission at between 850 to 928 MHz (also called the L Band) for sending the energy consumption information to the utility. The other emission is at between 4 KHz to 200,000 KHz called “conducted emissions” which is conducted on the house wiring. When a consumer decides to “Opt-Out” of a Smart Meter they typically remove the exposure of the Microwave emissions but not the conducted emissions. That is because the common “Opt-Out” meter is the identical meter of a Smart Meter but with the Microwave RF emission disabled. The Smart Meter and the Opt-Out meter use the same power supply and that is the root cause of the problem with bad EMC. The term “Dirty Electricity” was coined by the consumer community that felt the effects of EMC (Electro Magnetic Conducted) emissions to their bodies and really did not have the grasp of the technical characteristics to describe it so they considered it as polluted electricity and called it “Dirty Electricity”. Some people misinterpreted this term and think this describes electricity created from carbon based fuels such as Coal or Natural Gas, but it really is bad EMC coming from the poorly engineered power supply on the Smart Meter. The power supply is a SMPS (Switched Mode Power Supply) which is needed to convert the incoming 240 Volts AC to typically 12 Volts DC to power all the electronics. The switching characteristics of the main component of the SMPS is a electronic switching regulator operating at a fundamental frequency of between 16 to 120 KHz, plus all the harmonics of these frequencies at 32, 64, 128, 240, 480 and 640 KHz and some 2nd, 3rd and 4th order harmonics of all these frequencies. The result on an oscilloscope looks like what I have shown on page one of this web site.
OK, now what is EMC? EMC is an emission from the Smart Meter power supply that is Conduced/Injected onto your home wiring and is a series of high frequency pules radiating throughout the home turning the entire home envelop into a very large antenna. These pulses do not radiate very far in the radial plane but can travel laterally many miles of copper wire and is typically able to be detected 3 to 6 feet in distance from the wire itself. Since most household rooms are typically 12 feet wide, any person in a chair adjacent to a wall in that room would feel the effects of EMC.
EMC has two components RFI (Radio Frequency Interference) which can be easily detected by the presence of static noise. A typical AM radio tuned to a open frequency with no AM radio station present can be used to see if you have RFI. In my own home the RFI from the Smart Meter is so high that listening even to a strong local station is difficult because of all the static. The other component of EMC is EMI (Electro Magnetic Interference). This EMI causes strong magnetic fields in the near field of the home wiring. Since this created by the high frequency pulse of the power supply circuit in the Smart Meter this creates a pulsing magnetic field which can cause a number of detrimental effects to the body. It is not the magnetic field alone that causes the effects to the body, it is the constant cycling of the magnetic field on and off 4,000 to 200,000 times a second that is creating ill effects.
All this could have been avoided by the Smart Meter manufacturers by the inclusion of an EMC filter circuit on the power supply board. Their costs would have been about $2.00 in parts to fix this. All the electronic equipment in your home have a similar power supply as the Smart Meter only those appliances have all been required by the FCC to include an EMC filter within the power supply to avoid these same ill effects.
Now these high frequency oscillations are on your home wiring and are now at a high current of up to 200 Amps, courtesy of your utility. An in line, current carrying EMC filter that can handle 200 Amps is extraordinarily expensive to obtain costing anywhere between $5,000 to $10,000. Imagine all this high frequency pules on our home wiring could have been avoided for a simple addition of about $2.00 in parts to each Smart Meter.
The circuit diagram of a proper EMC filter is like this.
An EMC filter uses a concept called an X capacitor and Y capacitors along with a coil which neutralizes the magnetic pulses that result from these capacitors doing their job. In this diagram there are 2 X capacitors, one Y capacitor circuit and a pair of coils (called Current Chokes).
It physically looks like the left hand part of this circuit board.
Notice the yellow square part on the left side of the circuit board which is the Y capacitor and the two little blue parts nearby which are the two X capacitors and the part that has the shiny copper looking set of wires, that is the “Current Choke” and there are two of them in the same component frame. Everything to the right of these parts are the switching part of the power supply and its supporting other parts.
For those unfamiliar with electronics let me explain the diagram above. #1 and #2 is the input 240 Volts AC voltage coming into the circuit. #3 and #4 are the 12 Volts output DC of the power supply that would connect to power the other electronics. R1 is a small resistor which helps to clip the peak of the oscillations while the CX1 capacitor does its job of removing the larger peak of the oscillations. L1 represents what is called a current choke (a type of transformer coil) which neutralizes the magnetic field via current flow created by CX1 when it clips the oscillations to the opposing side of the AC cycle. That is reflected in the semi circular curve. Please note the AC is cycling from zero to full voltage and flips polarity 60 times a second. So while #1 is at full voltage #2 is at low voltage. This flips back and forth between #1 and # 2 60 times a seconds. The capacitor CX1 targets this high voltage and low voltage condition and the flipping of this high to low condition in order to do its job. CX2 does the same thing and it catches any remaining high transients after CX1 does its job.
Then you will also note the Y capacitors CY3 and CY4 which work in a similar fashion only instead of neutralizing one side of the high voltage to the low voltage side of the 60 cycle voltage change, it neutralizes the remaining transients to ground, as reflected by the symbol that looks like an upside down Christmas tree. L2 is another current choke coil to eliminate the remaining current created by the Y capacitors. The Y capacitor relies on a connection to ground, which is not present in all Smart Meters on the market. So to fix the Smart Meter would require a complete redesign of the power supply circuit board.
There only two options for a consumer to use to avoid all these effects. One is to revert back to an electromechanical meter (Analog Meter) that we have had on our homes for the last 80 years with no internal electronics or to install a parasitic EMC filter that cost much less that an inline current carrying EMC filter, but will still cost about $1,000 to obtain.
I have included here some links here on studies that document the known health effects of bad EMC.

The Richard Tell study is frequently the basis of many Utilities use in their talking points of the following example of their talking points such as:
- The SM is less than a baby monitor – of course they do not refer to what type of baby monitor and the power that it emits
- The SM is less than a cell phone – without discussing the huge difference between cell phone signal modulation being a full duplex transmission versus a half duplex transmission which is much more intense and results in a larger signal duty cycle.
- The SM is less than a door bell or garage opener – a totally ridiculous comparison
- The SM meets all FCC standards – of course they do not mention that the FCC standard is for heating effects only, not what the SM produces, also notice the duty cycle in this study, no SM other than this very specific model which has had its duty cycle reduced to only 11 secs a day is reflected in this study, Every meter we have tested has a much, much longer duration of transmission. With the duty cycle used in this study the SM is fundamentally OFF! Also note the study is based on MPE of thermal ionizing heating effects not the non ionizing effects of the SM.
