Default EU looking for comments on PLC – 10 days to respond – act today

The EU (European Union, AKA EEC) is looking to give the PLC industry a
blank cheque to pollute the shortwave with emissions from their broken
legacy technology. We must respond and submit comments before October
1st.

Check here;
http://europa.eu.int/information_soc...cocom03_32.pdf

And
http://europa.eu.int/information_soc...ns/text_en.htm

Notes for making a submission;

With respect (be polite NO FLAMES), you wish to point out that PLC has
experienced many problems and no technical data has been presented
that the PLC problems are resolved and the threats from PLC are very
significant.

Introduce yourself, if you have a particular expertise tell them.

Key is to support Broadband and offer positive alternatives such as
Wireless. Focus on all users of the shortwave, particularly where they
have no alternative. It is easy for the PLC industry to dismiss hams
bit more difficult when it comes to aeronautical radio and safety of
life communications.

Applaud and support the implementation of the Broadband imitative,
point out that Broadband can be delivered by many diverse means
including DSL, Cable, Wireless, Satellite etc.
WiMax in particular can make a significant contribution to Wireless
Broadband.

Intel has pledged to enhance WLAN standards and the technologies they
encompass to such an extent that copper cabling can be eliminated as a
network medium.

The shortwave spectrum is used for many diverse applications including
Broadcasting, Aeronautical, Radio Astronomy, Security, Amateur Radio,
most of which will have no alternative if PLC is permitted to create
interference. In addition the shortwave is used for point to point
links in other countries in particular the Third World and widespread
use of PLC could disrupt these communications.

Interference from PLC is very difficult to trace, when a licensed
radio service causes a problem it can be quickly identified and the
issue addressed. In the USA a division of the FAA reported that it had
to cease operations on one aeronautical band at one of its facilities
due to interference from PLC products and the FCC was unable to
resolve the issue.

PLC systems can suffer interference from licensed radio services and
strong local radio signals could also result in intermodulation
signals that could cause interference to FM radio and VHF aircraft
frequencies.

Japan has very extensive and inexpensive Broadband rollout and has
banned PLC due to interference concerns.

Slide 15 shows a 30 db increase in the noise level due to PLC.

Good information from the ARRL here;

PLC interference complaints are listed here;

Key that as many individual different submissions are made, focus on a
particular issue, make it your personal call for the shortwave – the
commons of the radio world be preserved. Also may like to contact your
MEP and raise the issue.

Please forward this email to anyone who can help, in particular other
European countries.
