I have AMIEE in electronics, and passed the radio comm part with distinction. Probably better qualified than you.
ALL homeplugs cause interference when used as intended, the laws of physics cannot be changed. I would also like to know what the claimed qualification actually is?. |

AMIEE was originally Associated Member of the Institute of Electrical Engineers. The IEE merged with the IIE in 2006 to form the IET, Winston will no doubt tell us if he is now an IET Associate or has upgraded to Member. AMIEE is not a qualification as such but there were restrictions on membership that were qualification dependant. In the old days, 1970's, you also had to prove you were in charge of a department of at least four people but I think that restriction disappeared years ago.
I'm sure he will be happy to tell us what qualifications he had at the time of his membership, thus clearing the air in this matter once and for all. http://www.theiet.org/membership/typ...atory-letters/ |

Powerline adapters are ok to use but I find that they do raise the noise floor on fm band 2, mw and sw bands.
I found mine to sometines drop the internet connections so decided to replace them all with wired ethernet connections. |

If you are qualified as you claim, then why do you post such total drivel?.
I would also like to know what the claimed qualification actually is?. |

HND electronics, followed by another year for College Diploma (Southall Tech), and the IEE exam granting Graduate membership later upgraded to Associate membership.

It is NOT drivel. You are clearly not qualified enough to understand.

The drivel you post rather shows that your claimed qualifications are either non-existent, or you didn't understand anything you were taught
![]() When you took the RAE to get your ham licence you must have studied the part about interference. Did you not understand it? |

Thank you, so just out of curiosity as the IEE no longer exists are you now an AMIET?

Yes, but you obviously don't - or even understand what 'interference' actually means - perhaps you should try consulting a dictionary?.
https://en.oxforddictionaries.com/de...n/interference That seems to sum it up quite well, exactly what Homeplugs do. |

Another error is that Power equals volts times amps times power factor.
Even if it were relevant, power factor is going to have an attenuating effect not an amplifying one. Quote:
Taking the error into account means up to 4 watts is radiated. No wonder there is so much interference. PLT has been shown to cause interference up to 500 metres. 4 watts into a decent aerial can go much further. Some TV relay transmitters are less than 4 watts.
So the total radiated power in my hypothetical example in to free space outside of the house would be considerably less than 4 Watts, but the interference received at ant aerial would be even less than that. |

2.1 The fading or disturbance of received radio signals caused by unwanted signals from other sources, such as unshielded electrical equipment, or broadcasts from other channels.
That seems to sum it up quite well, exactly what Homeplugs do. That's where your ludicrous drivel makes no sense. |

Except it's NOT - except in very rare cases, and in quite unusual circumstances.

It seems you will never believe hard proven facts. No drivel. PLT always generates interference in each and every case when used as intended. Whether that interference affects you personally or not is another matter.
Understanding this does not require a PhD in electronics, merely common sense.
