Using "HomePlugs"

I use them and experience no problems. I have also disconnected them and have noticed no difference in sound quality. I would try them. 

I use them and I'm a happy bunny.

Greensticks, good stuff. Let us know things progress with the hidef audio. You might just find 192/24 a struggle on wifi depending on environment and load on your wifi.

BTW you will also now be helping your Naim to sound at its best which has got tonbeen what it's all about.

Mains quality is so important. In my village the electricity network people have just replaced my aging discrete 4 wire overhead feed on my lane, with a twisted Aerial Bundled Cable feed, and the sound quality on the Naim has subtly improved, with that late night listening effect now seemingly available throught most if not all the day.

If you are concerned about health hazards caused by Homeplugs why are you not concerned about any perceived health hazards caused by WLAN? The RF radiated will be at a far greater level than any Homeplug. And as for all those cellular phones, overhead power lines, etc. it's a wonder any of us get any sleep at night.

PDave4jazz, the wideband radio emission bandwidth relative to the radio frequency between wifi and Homeplugs is immense.

The field strength exponential fall off is proportional to the radio frequency wavelength, or inversely proportional to the wavelength.

Homeplugs tend to transmit wide and from 3 MHz to 28MHz and now upto 400 or so MHz for the higher bit rates.

Therefore at 3 MHz the wavelength is around 100metres or so.

For wifi the wavelgth is approx a couple of centimetres or less, so the radio field falls significantly away quickly as you  move from the antenna by two or three centimetres. Contrast that for 3Mhz to 28 MHz where the wavelength vary from 100m through to 10m... so although power levels are very  low, depending on the emission from the mains wiring geometry, close extended proximity to mains wiring, like within a metre.. Such as sleeping next to a mains powered alarm clock radio or bedside reading lamp would cause me concern.

Slightly going off topic, but hey why not , last year I heard an amateur radio transmission on the 10m band using between 10mW and 100mW into a wire antenna from a balcony in London talking to station in the Canary Islands. I have had a fairly comfortable dialogue using about 10 Watts ERP to Australia on the 17m band, and that was with the Sun activity at middling levels.

Simon  - Your comments on the radio emissions from HomePlugs is scaring me, it makes it sound as if the house is a mini Microwave cooker if a HomePlugs are used anywhere in the house.

You also make it sound that the radiation from a neighbours property could be quite stroong if they are using HomePlugs

What research has been carried out on the effects of this type of radiation on humans.

Thanks for any information

Derek, sorry I didn't mean to scare, I just felt it was pointing out all is not as it seemswhen left to marketing and lobby groups. 

As far RF exposure safety levels, the UN( WHO), IEEE and other bodies have established field strength safety standards. These vary on whether limited exposure or long term and are largely based on the heating effect to the body. 

It is fair to say that for Wifi and Homeplugs you are well within these safety field strength levels when being used as intended.

However research continues into other biological effects other than heating such as long ter exposure to low level EMI. 

Here is a good source of info, but need to look out for the more controversial low level long term RF exposure.

It is worth pointing out it the home wiring that acts as the radiating antenna with Homeplugs rather than the devices themselves. This makes actual radiation and any potential health impact very site specific, which is one of the issues. But please remember the power level on Homeplugs is very low.. The issue are IMO that it is broadband ie many multiples of  RF carriers and the length of time of exposure so the average power exposue becomes less trivial in a typical domestic environment. That and the relatively long wave lengths used gives me concern in a typical house.

I would not use them because of this, even I had no radio or hifi.

BTW the field level if a neighbour was using such devices would be extremely low and I can't see any health impact at all in such a scenario. At worst the issue here could be the nuisance / interference factor.

Following your comments I have removed Homeplugs from the home LAN.

Thanks for your comments.

Greensticks and Adrian, thanks for your comments, and not wishing to court controversy (perhaps more than I have done..) I endorse the actions you have both taken, and keep on enjoying  those late night listening sessions 

BTW i agree bouncing signals off the ionosphere certainly has some interesting science, but a bit like long range weather forecasting indeed turns into more of an art and chance.

I still find bouncing a signal several hops to the other side of the world cool.
