Hi!
I've read several post about Graham-stetzer filter and meter and other brand of this stuff but i like to know if anybody ever herd or tried this model (RxDNA is for home VS MxDNA for industrial) ??? RxDNA dissipate the noise as heat and you plug one in each phase of the house (normally 2) Some say that Stetzer filter was damming the noise and getting a not so good feeling effect about it and prefer other filter system ...I personaly bought a Graham-meter and 2 filter to test but cant see a reduction in EMF so im wondering if its working beside the lower number on the meter I get ! A link with PDF spec. http://rfreduce.com/mxdna/ here's a reseller http://www.oxygen-products.com/rxdna.htm and another site ... seems to be the maker http://www.nobleelectronics.net/Boe1.html |

If you want to measure the radiated kHz range "noise" you cannot use a
Trifield Meter.

You cannot measure dirty electricity with a Trifield meter.

> Use an AM radio
Question: An AM Radio is commonly recommended here as an alternative to an EMF meter. An AM Radio receives signals from 500 - 1600 khz. I'm wondering if there would be any advantage in seeking out a radio that receives "longwave" broadcasts (150 - 300 khz), or "shortwave" broadcasts (1700 - 30000 khz). Perhaps there are some harmful frequencies that would be picked up by these radios that are not picked up by an AM Radio? Marc |

> as for witch device work the best for EMF or Dirty Electricity > removal ??? I suppose it depends on what your goal is -- to reduce the readings on your meter, or to feel better? I've tried various filters that measurably reduce the dirty electricity meter readings (Stetzerizer meter, Entech meter), but sometimes that makes no difference in how I feel, and sometimes I actually feel worse from these filters! Meanwhile there are things like the Quantum Home and Earthcalm Home which have NO impact on these meters, yet do make me feel better. That said, I do use a Furman "linear filter" power strip (PST-8,PST-10) for my computer & TV stuff, which does reduce the meter readings without making me feel worse. :-) Marc |

For a while I had one. It picked up some things, but
usually I found using it in AM mode was sufficient. I think for most sources, it's better to have as big a bandwidth as possible. Cheaper radios usually have broader bandwidth. I'm also starting to think, if you get to really big bandwidth, you want to make sure the system is "phase linear" which means only first order filters (The Ramsey ABM1 has incredible 18MHz bandwidth, but the filters are not first order so the bandwidth is basically wasted unless you build it from the kit version and bypass the filters). The MFJ-856 has about 100kHz bandwidth, versus about 10kHz for an AM radio, and I have reason to think it is phase linear. There is also a version with a smaller nondirectional antenna which LessEMF sells as the Power Line Noise Finder or something. I think anyone who has $160 left after buying their microwave meter should get one of these. A Tri-field meter is good to have too, (with 100x external probe if you have low enough fields) but for some people the MFJ-856 will be more important.

It's tough to get a filter that really works unless it has
a good ground that you don't mind contaminating (i.e., the whole thing is far away from you). I would not bother with Stetzer filters (they might help if you are far from it and there is a bad magnetic EMF source on the circuit). You want a big heavy multistage filter. But even then you can create ground loops. The easiest thing is to replace newer wall warts with the old linear (preferably regulated) kind. Jameco sells some.

Isn't the Stetzer filter in a working range of 4kHz to 100kHz so Isn't the AM radio a bit out of range with its 500 - 1600 khz Marc ? If you take a good feeling approach for filtering effectiveness maybe the narow 4kHz to 100kHz filtering capability of the stetzer arent enoughf ? The RxDNA is approximately 5 Khz to 500 Khz in range ...maybe this does make a difference for some ! The guy who prone me these one told me about his particular home condition and the bad feeling he got with the Stetzer filter as they actually worsen the problem (more EMF)and then install the RxDNA and had such a calm feeling after installing them so that's why I was asking if they where really that good ! Anyway I have 2 old 70's hand held 9V AM radio ... Im gonna make some more test to try this theory :) --- In [hidden email], Bill Bruno <wbruno@...> wrote: > > For a while I had one.

An HP Network Analyzer would be cool-- probably too expensive, though: http://www.dxengineering.com/TechArticles.asp?ID={1D9AAC83-E591-46D4-86AE-B84F1CBF1D62} Check youtube for lots of videos about plasma TV RFI.

Hmmm, I've got a filter which has a far greater range than the Stetzerizer filter, but it makes me feel worse in the same way as the Stetzer filter. So there's more to it than simply frequency range -- I just don't seem to do well with the parallel capacitor shunt filters. > The guy who prone me these one told me about his particular home > condition and the bad feeling he got with the Stetzer filter as they > actually worsen the problem (more EMF)and then install the RxDNA and had > such a calm feeling after installing them so that's why I was asking if > they where really that good ! See, now that's a more interesting testimony -- someone who felt bad from the Stetzer filter but better with the RxDNA. (I've got some "Noise Harvesters" from PS Audio, which turn noise into light instead of heat, but never noticed any improvement from these) Marc |

I have a Brick Wall Line Conditioner on my TV, VCR, etc and when my neighbor uses her treadmill I get static on the TV. I was disappointed. I was thinking of getting the Furman then I started reading reviews of the Tripplite Isobar surge line and people are getting good results for only around 70 bucks.

Hmmm, I would have thought the Brick Wall would have been pretty good. In my power strip testing, the Furman reduced more noise than the IsoBar or the Brick Wall. Marc |

Well are all the devices you tried an kinna fail your testing all base on Capacitor storing,filtering or converting to good energy ?

If the light flash it should be store till enough then discharge the capacitor into a flash of light! > > Marc > Funny what you can do with energy ... I use to test a tiny radiant energy device that with only 30 milliamps DC ,I can load a big capacitor by capturing the energy spikes with it up to 200-300 Volts and made a heck of a snap when discharging it ! The capacitor or a lead battery is able to store and change that useless to mankind energy to useful one but Is the process EMF free ? So I'm am wondering with all the spikes of energy in the wiring how can a tiny led light do much good as can it burn all that energy with just one unit ???? Yes maybe with 20 or 30 units ???...Correct me if I'm wrong ! But is the processing EMF free ? |

> Well are all the devices you tried an kinna fail your testing all base on
> Capacitor storing,filtering or converting to good energy ? The filters which make me feel worse are the type that collect the noise on the hot line and then transfer that noise to the neutral line ("shunt capacitor filter"). The Stetzerizer filter and the Blue Circle Audio BC86 fall into this category. This is also how a lot of "hardware store" power strips with EMI filtering work. However, I have no worsening of symptoms with Furman linear filtering powers strips, or the PS Audio Noise Harvesters. > Are these units also have a capacitor system to store and then burn (in a > way of saying it)the extra into light ? > If the light flash it should be store till enough then discharge the > capacitor into a flash of light! Yes, this is how the Noise Harvesters work -- they store the noise, and when the capacitor is full, an LED flight flashes. When there is a lot of noise on the line, those things will flash so often that it almost appears to be continuous light. In such cases, the company recommends that you buy more Noise Harvesters. And indeed, if I plug in a second Noise Harvester next to the first, the rate of flashing on the first Noise Harvester decreases. So it seems to me that the RxDNA might be somewhat like the Noise Harvesters, except maybe that it turns the noise into heat rather than light, and also that they recommend fewer per house, so it must have more noise removal capacity. But like I said, I never noticed any improvement in my health from the Noise Harvesters, so I wonder if the RxDNA would be any different? Marc |

> So it seems to me that the RxDNA might be somewhat like the Noise
> Harvesters Doing a bit of searching on the Noise Harvesters, I find sketchy and conflicting information, but according to some sources, the Noise Harvesters only focus on noise in a very narrow range: 8 khz - 15 khz (and presumably higher frequency harmonics from this), and remove "8 - 10 watts of line noise per day". The information on the RxDNA is more specific -- works in a much larger frequency range (5 - 500 khz), and removes 60 watts of line noise. (I don't know if this 60 watt number can be directly compared with the 8 - 10 watts PER DAY number). Also, for the Noise Harvesters, they recommend 5 per house ($500), while for the RxDNA they recommend 2 per house ($1400). (with Stetzerizer filters recommended at 20 per house, and the Quantum Home recommended at 1 per house). Marc |

Richard Conrad tells me the "Audio Power Industries" Ultra series
