FCC News: FCC Expands Part 95 MedRadio Rules to Allow Devices in 2360-2400 MHz Band
In a First Report and Order and a Further Notice of Proposed Rulemaking (ET 08-59) released on May 24, the FCC decided to expand the Part 95 Personal Radio Service rules to allow medical devices to operate on a secondary basis in the 2360-2400 MHz band. These devices -- called Medical Body Area Networks (MBAN) -- provide a way for health care facilities to monitor their patients via wireless networks. Because use of these frequencies will be on a secondary basis, MBAN stations will not be allowed to cause interference to -- and must accept interference from -- primary services, including radio amateurs who operate on a primary basis in the 2390-2395 MHz and 2395-2400 MHz bands.

MARS: House Armed Services Committee "Urges" MARS Coordination
On May 18, the US House of Representatives approved HR 4310, The National Defense Authorization Act for Fiscal Year 2013. This bill authorizes appropriations for military activities and prescribes military personnel strengths for Fiscal Year 2013. When the House Armed Services Committee sent the bill to the House, it included language in support of the Military Auxiliary Radio System (MARS) and called for the three MARS branches -- Army, Air Force and Navy/Marine Corps -- to be brought under one umbrella.

On the Air: Have Some Fun in the 2012 ARRL June VHF QSO Party
There will be lots of RF generated on 6 meters and up the weekend of June 9-11 during the 2012 ARRL June VHF QSO Party. While many amateurs think of the VHF+ bands as a "local" band for public service, emergency communications or even a bit of fun on FM repeaters, weak-signal VHF+ enthusiasts know better. Even with a modest station, it's possible to work hundreds -- or even thousands -- of miles on the VHF bands during a good opening.
ARRL Contest Branch Manager Sean Kutzko, KX9X, is a big VHF enthusiast. "In more than 25 years of Amateur Radio, weak-signal work on 6 and 2 meters remains the most fun and intriguing activity I do," he said. "There is nothing like a good VHF opening -- with interesting propagation characteristics like Sporadic-E, tropospheric ducting, aurora and even meteor scatter and moonbounce -- VHF offers QSO opportunities that HF can never satisfy."
