Against Power Line Ethernet (PLT)
That uses the short wave radio spectrum
Probably the worst thing to happen to Shortwave radio ever!

How to report this interference (There is no COST!)
See the Governments reply to our last petition (off site page)
Urgently sign up to the new petition (UK only) and help us build on the last.

UKQRM Press release (pdf download)
UKQRM is invited to Ofcom's London office
What does UKQRM stand for? UK as we are based in the UK and QRM is the radio code for Man-made interference, such as that from badly made equipment. There are many so called 'Q' codes click here for some more information.
Are we going to stand by and allow the whole sale jamming of the short wave radio spectrum?

about the
problem in non technical language
British Telecom with its BT Vision package and many independent electrical and computer stores/outlets are supplying power line adaptors to as many homes as they can!
What's wrong with that you might ask?
Well there is one element of this package that is causing the death of short wave radio!
Shortwave radio is
the medium used by most International Broadcasters to transmit
their programming to the World. Commonly referred to as World
Band Radio, it has amazing properties that allow world wide
communications and it has been in use since Marconi made his
first historic transmissions.
Shortwave broadcasts are found in the 2Mhz to 30Mhz band of the
radio
spectrum (just above the Medium waveband) and include many
thousands of users: Military, Shipping, Long Range Aircraft
communication, Space, Amateur, safety of lives and World
Broadcasters.
Many Millions of
people listen to short wave radio every day, some relying on it
for their very existence.
Modern short wave equipment is very sophisticated and can even be
computer controlled.
Shortwave radios cost from a few pounds to many thousands of
pounds (GBP £) There is a huge world market in shortwave
equipment!
We believe it is of paramount importance that its uninterrupted
use is
maintained and protected.

Yet despite all
this various companies have chosen to ignore this and obliterate
this well used and loved radio band.
UKQRM is a group for
people to come together and fight against this stupid poorly
designed and questionable technology!
Its Piracy pure and simple
The problem is caused by
the Power Line Adaptors (Powerline Ethernet)
These are used to set up a home network by passing signals over the mains wires of the house! carrying video and data. To do this they use the almost all of the shortwave spectrum 24 hours of every day! even while no data is being passed.
The result is that the mains wires being unscreened act just like antennas and broadcast the video/data far and wide outside of the house concerned!
This has little to do with Internet access or being connected! you don't need power line ethernet to use the Internet or even BT Vision! UKQRM is not trying to stop people being connected to the Internet, why would we? we all use it every day.
Have a look at our videos page to hear and see the problem.
Many thousands of
people use and listen to short wave radio every single day here
in the UK and more around the globe, its uniqueness and ability
to allow far flung stations around the world to be tuned in from
the comfort of your arm chair has fascinated and delighted
generations.
This is all under threat now!
There are two types of these terrible adaptors!
Universal Powerline Association (UPA) as used by the BT Comtrend adaptors and Home Plug Power Alliance (HPA) less intrusive but still a problem! Our main focus is the UPA type but we are also very concerned about the HPA and any type of Power Line Communication.
Join us at UKQRM if you are suffering from this interference or
feel you could contribute to our very active group.
Make your stand today, tomorrow really will be too late!

28th October 2008 Ofcom have announced their intention to investigate complaints of PLT interference and have set up a special phone number for reporting.

The Wireless Telegraphy Act
2006 has been deemed not to apply to PLT despite the fact that
PLT is indeed a radio transmitter. It would not work without
generating and transmitting
radio energy into the mains wires which are no different from any
other unscreened wire.
However the EMC regulations do apply and we feel that PLT does
not meet them!
EMC Essential requirements are:
Equipment shall be designed and manufactured, having regard to
the state of the art, so as to
ensure that
(a) the electromagnetic disturbance it generates does not exceed
a level above which radio
and telecommunications equipment or other equipment cannot
operate as intended; and
(b) it has a level of immunity to the electromagnetic disturbance
to be expected in its
intended use which allows it to operate without unacceptable
degradation of its intended
use.
Part III, General Requirements - Apparatus:
15.No person shall place on the market apparatus unless either
the following requirements, or
the corresponding requirements of the EMC Directive as
implemented under the law of another
state in the Community, are met.
