<H1>Homeplug user – 'should I feel guilty about ham radio?'</H1>
<P><FONT face=Verdana>An article on NewsWireless.net by respected technical
journalist <STRONG>Guy Kewney</STRONG> mentions the problems that
<EM><STRONG>HomePlug</STRONG></EM> power-line communications (PLC) systems cause
to those who listen to short wave radio.</FONT></P>
<P><FONT face=Verdana>However, it's not just radio listeners who are affected by
these devices, it appears they can also affect some wireless keyboards and mice,
Guy quoted Steven Routly who posted this in the Comtrend Forum:</FONT></P>
<P><FONT face=Verdana>"I have just installed BT vision with a pair of Comtrend
adapters, and now my wireless Logitech keyboard and mouse do not work properly
(act like they are drunk ) miss letters and work slow. I can turn the problem on
and off simply by putting the Comtrend adapters in standy or on, so they are the
cause of the problem,” .</FONT></P>

<P><FONT face=Verdana>The potential problems devices like 'Homeplug' could cause
to peoples' radios were mentioned in the December 2007 issue of Personal
Computer World (PCW) magazine which said</FONT></P>
<P><FONT face=Verdana>"Mains wiring acts as an aerial when passing
radio-frequency data signals and, as we have reported before there are fears
about the cummulative effect in cities if the technology gets taken up on the
same scale as WiFi."<BR>(see </FONT><A
