ARRL Files Federal Court of Appeals Reply Brief over BPL On July 31, the ARRL filed its reply brief at the US Court of Appeals for the District of Columbia Circuit. This brief follows the FCC’s brief that attempted to rebut the ARRL’s challenge to the FCC’s Broadband over Power Line (BPL) rules enacted in late 2004 and affirmed by the agency in 2006. According to ARRL General Counsel Chris Imlay, W3KD, “The FCC’s brief does not accurately describe ARRL’s arguments concerning harmful interference.” The ARRL, in its reply brief, accuses the FCC of, “engaging in misdirection — rebutting hyperbolic arguments ARRL never made, refusing to address the precedents ARRL cited and attempting to rewrite the Orders as if they made factual rather than legal determinations.”
ARRL Files Objection to Ambient’s BPL Experimental Authorization Renewal Request
On July 25, the ARRL filed an Informal Objection to Ambient Corporation’s request for a renewal of their nationwide experimental authorization that allows them to operate broadband over power line (BPL) operations anywhere in the country they choose. Ambient has been operating its BPL equipment under experimental authorizations for more than five years, an unusual amount of time for an experimental authorization. An Informal Objection is the procedure dictated by the FCC’s Part 5 rules protesting the renewal of an experimental authorization. Currently, Ambient currently operates a BPL system in Briarcliff Manor in Westchester County, New York. Other installations have apparently been shut down by Ambient.
Tokyo to Host World’s Tallest Tower
Wired.com says the tallest broadcasting tower ever built is coming to Tokyo, Japan.. The 2001 foot high structure, which still doesn’t have a name, will host the digital radio and television transmissions plus a mobile TV network. When completed in 2011 the concrete-and-steel tower will be the highest free-standing antenna in the world. (ARNewsLine)

New Thinking on Time Travel
Astrophysicists pondering the subject of time travel have postulated not only whether time travel is theoretically possible but whether it is technically achieveable. The popular concepts using black holes, wormholes, and cosmic strings are not practically possible because they basically require the ability to harness energy equivalent to an exploding star and an inconceivable amount of mass. A more down-to-earth concept has been proposed. Physicist Ronald Mallett is known for his expertise in general relativity, gravitation, black holes, relativistic astrophysics, and quantum cosmology. He has been working with Einstein’s equations for years in an attempt to design a sort of time machine. Professor Mallett has devised an alternative to these time travel methods based on Einstein’s famous relativity equation: E=mc2.
"Einstein showed that mass and energy are the
same thing," said Mallett, who published his first research on time travel back in 2000, which appeared in the
journal Physics Letters. "The time machine we've designed uses light in the form of circulating lasers to warp or
loop time instead of using massive objects." In attempting to create a "time loop", Mallett is tinkering with a
sevice to test his time-warping theory. Using mirrors, Mallett hopes to create a circulating light beam that can
warp surrounding space, which is part of his work called The Space-time Twisting by Light (STL) project.
According to Einstein, whenever you do something to space, you also affect time. Twisting space causes time
to be twisted, meaning you could theoretically walk through time as you walk through space. Lest amateur
radio operators get their hopes up for one more QSO via AO-40 or a chance to snag the missed DXepedition,
Professor Mallet has a 'futhermore': "The Grandfather Paradox [where you go back in time and kill your
grandfather] is not an issue," said Mallett. "In a sense, time travel means that you're traveling both in time and
into other universes. If you go back into the past, you'll go into another universe. As soon as you arrive at the
past, you're making a choice and there'll be a split. Our universe will not be affected by what you do in your
visit to the past."
