<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>
