Broadband Over Powerline Brings Smart Grid to Rural Areas:

E-mail Print PDF
IBM and the International Broadband Electric Communications are running trials of smart grid services using broadband over powerline communications. The two companies hope billions in stimulus money could boost the use of transmission lines for smart grid communication in rural areas. Part of the slow pace of deployments had to do with the opposition of ham radio operators, who complained that older versions of BPL interfered with their frequencies. In April 2008, in a lawsuit brought by the American Radio Relay League ham radio association, a federal court ruled that the FCC had to rewrite its BPL regulations to solve that problem. BPL companies solved that problem by "notching" the frequencies they used to avoid those that interfered with ham radio, Blair said. Likewise, glitches that have plagued the technology in the past have been worked out, he said. He pointed to Texas utility CenterPoint, which has been operating an IBM-designed BPL network for the past two-and-a-half years, as an example.

2009's Sleepy Sun Finally Woke Up in December:

E-mail Print PDF
2009 will go down as the sun's third quietest year on record, under-shone only by 1913 and 2008. Two hundred-sixty of the year's 365 days (71 percent) were sunspotless. Last year saw 266 sunspotless days, while the sun had no spots on 311 of the days in 1913. It was only a very active December that kept 2009 from falling below last year's mark. Sunspot activity waxes and wanes in a roughly 11-year cycle, so hitting solar minima isn't surprising. But what the numbers underscore is that we spent much of the year still in the midst of the deepest, longest solar minimum in a long time.

QRP "Over the Top" for the Colorado 14er Event

E-mail Print PDF
After reading the August 2005 QST article by Chris Ormsby, K0CAO, and Bob Witte, K0NR, I thought what fun a HF low power (QRP) operation from a Colorado 14er (A mountain over 14,000 feet high.) would be. The “carrot” would be that an out-of-state 14er to 14er HF contact had yet to be made.1 After the N7UN and WG0AT fun-packed hike through the Canyonlands National Park in April 2008, Steve and I made plans to participate in this unique Colorado operating event. 2 It was after we heard that Brian Boschma, N6IZ, was planning to HF QRP activate Mt Whitney (14,491 feet) the same weekend as the Colorado 14er event that our mutual plans solidified. We would take a crack at making the first out-of-state summit HF QRP contact between a Colorado 14er and Mt Whitney in California.
