Smartphones on planes: Pilots say it is critical to turn off devices | FP Tech Desk | Financial Post
Public figures from U.S. Senator Claire McCaskill to actor Alec Baldwin have bristled at what they say are excessive rules restricting use of tablets, smartphones, laptops and other devices during flights.

More than a decade of pilot reports and scientific studies tell a different story. Government and airline reporting systems have logged dozens of cases in which passenger electronics were suspected of interfering with navigation, radios and other aviation equipment.

The FAA in January appointed an advisory committee from the airline and technology industries to recommend whether or how to broaden electronics use in planes. The agency will consider the committee’s recommendations, which are expected in July, it said in a statement.

Citizen - News | Turn these devices off
Bundesnetzagentur (BNetzA).

BNetzA is responsible for assigning frequencies to companies or organizations with a wireless requirement, including cell phone providers.

BNetzA also publishes the German Telecommunications Act (TKG). According to the TKG, those caught using a frequency not assigned to them fall subject to fines, which will increase the more they commit the offense.

The TKG defines an illegal operator as anyone who “… intentionally or negligently, uses frequencies without an assignment. In such cases the offense may be punishable by a fine.

Simple elixir called a 'miracle liquid' - Los Angeles Times
a simple mixture of table salt and tap water whose ions have been scrambled with an electric current. Researchers have dubbed it electrolyzed water -- the miracle liquid -- That's as good a name as any for a substance that scientists say is powerful enough to kill anthrax spores without harming people or the environment. Drawbacks: doesn't last long, machines expensive, not a "cure all"

Attenuation & Power Handling Calculator
The calculator above can be used to estimate the attenuation (dB loss), power handling capability, and transmission efficiency for some of the more popular Wireless Communications and MIL Spec cables at the frequency of interest (below Cutoff Frequency). Actual measured values may vary somewhat from the calculated numbers based on manufacturing tolerances, cable length, connectors, operating frequency, and measurement accuracy. The attenuation of cables with Bare Copper and Tinned Copper outer conductors can vary substantially from the theoretical value due to oxidation and therefore we recommend they not be used above 1 GHz. Note: the outer conductor of LMR cables is the aluminum tape."

Amazon.com: Philips SCS3012 300mAH Universal AC Adapter: Electronics
Finally, although you might have trouble figuring out which polarity to use, it would be unusual for the ring to be (+) positive and the inner conductor (tip) to be negative. That is, the polarity switch would normally want to be in the UP position ( (+) on the tip not the ring of the connectors). Any equipment that had so-called positive-ground (unusual) design would probably also have reverse-current protection.
