2-meter band

The 2-meter amateur radio band is a portion of the VHF radio spectrum, comprising frequencies stretching from 144 MHz to 148 MHz in International Telecommunication Union region (ITU) Regions 2 (North and South America plus Hawaii) and 3 (Asia and Oceania) and from 144 MHz to 146 MHz in ITU Region 1 (Europe, Africa, and Russia). The license privileges of amateur radio operators include the use of frequencies within this band for telecommunication, usually conducted locally within a range of about 100 miles (160 km).

Operation

Because it is local and reliable, and because the licensing requirements to transmit on the 2-meter band are easy to meet in many parts of the world, this band is one of the most popular non-HF ham bands. This popularity, the compact size of needed radios and antennas, and this band's ability to provide easy reliable local communications also means that it is also the most used band for local emergency communications efforts, such as providing communications between Red Cross shelters and local authorities. In the US, that role in emergency communications is furthered by the fact that most amateur-radio operators have a 2-meter handheld transceiver (HT), handie-talkie or walkie-talkie.

Amateur radio

Amateur radio (also called ham radio) describes the use of radio frequency spectra for purposes of non-commercial exchange of messages, wireless experimentation, self-training, private recreation and emergency communication. The term "amateur" is used to specify "a duly authorised person interested in radioelectric practice with a purely personal aim and without pecuniary interest;" (either direct monetary or other similar reward) and to differentiate it from commercial broadcasting, public safety (such as police and fire), or professional two-way radio services (such as maritime, aviation, taxis, etc.).

The amateur radio service (amateur service and amateur-satellite service) is established by the International Telecommunication Union (ITU) through the International Telecommunication Regulations. National governments regulate technical and operational characteristics of transmissions and issue individual stations licenses with an identifying call sign. Prospective amateur operators are tested for their understanding of key concepts in electronics and the host government's radio regulations. Radio amateurs use a variety of voice, text, image, and data communications modes and have access to frequency allocations throughout the RF spectrum to enable communication across a city, region, country, continent, the world, or even into space.

Tesla Model S

The Tesla Model S is a full-sized all-electric five-door, luxury liftback, produced by Tesla Motors, and introduced in June 2012. It scored a perfect 5.0 NHTSA automobile safety rating. The United States Environmental Protection Agency (EPA) official range for the 2012 Model S Performance model equipped with an 85 kWh (310 MJ) battery pack is 265 miles (426 km), higher than any other electric car at the time. EPA rates its energy consumption at 237.5 watt·hour per kilometer (38 kWh/100 mi or 24 kWh/100 km) for a combined fuel economy of 89 miles per gallon gasoline equivalent (2.64 L/100 km or 107 mpg_-imp).

The Model S became the first electric car to top the monthly new car sales ranking in any country, twice leading in Norway, in September and again in December 2013; and also in Denmark in December 2015. Global Model S sales passed the 100,000 unit milestone in December 2015.

The Model S ranked as the world's best selling plug-in electric vehicle in 2015, up from second best in 2014. The Model S also ranked as the top selling plug-in electric car in the U.S. in 2015.As of December 2015, the leading markets are the United States with a 60% share of global sales and Norway with 9.4%. Other leading country markets are China, the Netherlands, Canada, Denmark, Germany, and Switzerland .As of December 2015, the Model S ranks as the world's second best selling plug-in car in history after the Nissan Leaf.
