<h1>Amateur Radio suffers setback in surveillance robot battle</h1>
<p><font face="Tahoma">A robot used to covertly transmit live video during
military operations in Iraq and Afghanistan was approved by the Federal
Communications Commission (FCC) for use by local and state firefighters and
police, ending a legal battle between amateur radio operators and law
enforcement over the device. <br><br>Called the <strong>Recon Scout
Throwbot</strong>, the robot transmits over the 430-448 MHz portion of the
420-450 MHz frequency band, which is primarily used by the federal radiolocation
service. The spectrum is also utilized by amateur radio enthusiasts. The latter
group, spearheaded by the <strong>American Radio Relay League</strong> (ARRL),
opposed a waiver request filed with the FCC by Recon Scout maker ReconRobotics
Inc. to use the band.<br><br>The ARRL argued that ReconRobotics’ claims that the
device would be useful in public safety and anti-terrorism operations didn’t
prove that a waiver to use the frequency bands was in the public interest. The
FCC admitted, in its </font><a href="http://hraunfoss.fcc.gov/edocs_public/attachmatch/DA-10-291A1.pdf" target="_blank"><font face="Tahoma">order</font></a><font face="Tahoma"> approving the
waiver, that while some interference in the frequency bands may occur, it isn’t
a reason to prohibit the use of the Recon Scout. <br><br>The FCC approval does
come with some limitations, however. The robot can only be used by state and
local police and firefighters on the specific band. Operators must also first
use the Recon Scout on 436-442 MHz bands. If those frequencies are inaccessible,
then the 430-436 MHz and 442-448 MHz bands — where interference is more likely —
can be accessed.<br><br>In a subsequent Order on Reconsideration released April
15, the FCC </font><a href="http://www.fcc.gov/Daily_Releases/Daily_Business/2011/db0415/DA-11-675A1.pdf%20" target="_blank"><font face="Tahoma">granted</font></a><font face="Tahoma"> the ARRL’s
request for changes in the labeling and instruction manual requirements to
ensure that users of the Recon Scout are aware of the interference limitations.
<br><br>Use of the device is also limited to emergencies involving threats to
the safety of life and training purposes. In addition, the Recon Scout is
restricted from use near various radar installations and Air Force bases, and
the amount of units that can be sold is limited to 2,000 the first year and
8,000 the second year. After that period of time, future sales will be
re-evaluated, according to the FCC.</font></p>
