Isto assim agora já pia finiho!!!!...existem satélites bem sensiveis aos sinais mais fracos, como por exemplo a série COSPAS SAT, de socorro, que conseguia captar uma harmónica de menos de 1 mW, em 121.500 KHz que era emitida por uma emissor la no batente, (20 X 6075 KHz), e tivemos graves problemas com essa QRG por isso!...Não estou a ver essa porcaria a fazer QRM pela banda da aviação civil, até porque nessas frequencias o alvcance pode ser muito grande com pequenas potencias...Alguem tem que parar esses "parvalhões" que julgam que o espectro radioeléctrico é so deles!!!<div>

<h1>Interference from Gigabit Mains Ethernet adaptors</h1>
<p>A posting on the <strong>UKQRM</strong> list has raised concerns about <strong>interference from Gigabit mains Ethernet adaptors to the VHF Amateur and Amateur Satellite service allocations</strong>.</p>
<p><strong>The Belkin 'Gigabit' Powerline transmits a broadband signal down the household mains that extends from 50-300 MHz</strong>. </p>
<p>The report on UKQRM indicated that it may not have any notching enabled in key parts of the spectrum such as 50-54, 70.0-70.5, 144-148 MHz and the US 222-225 MHz band and could result in significant interference to the Amateur and Amateur Satellite services.</p>
<p>The UKQRM group is opposed to power line adaptors that cause harmful interference. The groups Yahoo email reflector is at<br><a href="http://tech.groups.yahoo.com/group/ukqrm/" target="_blank">http://tech.groups.yahoo.com/group/ukqrm/</a></p>

<br></blockquote></div><br><br clear="all"><br>-- <br>Best 73 from: regards from: CT4RK Carlos Mourato - Sines - Portugal<br><br> Save the Radio Spectrum! Eliminate Broadband over Power Line. Salve o espectro electromagnético!. Não use a rede electrica para transmitir dados. Os "homeplugs power line" e a tecnologia "power line" causa fortes interferencias noutro serviços sem voce se aperceber. Diga não à tecnologia power line. Proteja o ambiente<br>
