Amateur Radio
Amateur radio, also known as ham radio, is the use of the radio frequency radio spectrum, spectrum for purposes of non-commercial exchange of messages, wireless experimentation, self-training, private recreation, radiosport, contesting, and emergency, emergency communications. The term ''"radio amateur"'' is used to specify ''"a duly authorized person interested in radioelectric practice with a purely personal aim and without wikt:pecuniary, pecuniary interest"'' (either direct monetary or other similar reward); and to differentiate it from commercial broadcasting, public safety (police and fire), or two-way radio professional services (maritime, aviation, taxis, etc.). The amateur radio service (''amateur service'' and ''amateur-satellite service'') is established by the International Telecommunication Union (ITU) through their recommended radio regulations. National governments regulate technical and operational characteristics of transmissions and issue individual station li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

6 Meters
The 6-meter band is the lowest portion of the very high frequency (VHF) radio spectrum (50.000-54.000 MHz) internationally allocated to amateur radio use. The term refers to the average signal wavelength of 6 meters. Although located in the lower portion of the VHF band, it nonetheless occasionally displays propagation mechanisms characteristic of the high frequency (HF) bands. This normally occurs close to sunspot maximum, when solar activity increases ionization levels in the upper atmosphere. Worldwide 6-meter propagation occurred during the sunspot maximum of 2005, making 6 meter communications as good as or, in some cases and locations, better than HF frequencies. The prevalence of HF characteristics on this VHF band has inspired amateur operators to dub it the "magic band". In the northern hemisphere, activity peaks from May through early August, when regular sporadic E propagation enables long-distance contacts spanning up to for single-hop propagation. Multiple-h ...

Yaesu VX-5R Model
is a district in Chūō, Tokyo, Japan, located north of Ginza, west of Nihonbashi and Kyōbashi, and adjacent to the east side of Tokyo Station. The Yaesu exit of this station, which faces Nihonbashi, is a recent addition and primarily provides access to the Shinkansen platforms. History The area was named after the 17th century Dutch adventurer Jan Joosten van Lodensteijn, or simply Jan Joosten. For his services to Tokugawa Ieyasu he was granted a house in Edo (now Tokyo) in an area that came to be called "Yayosu Quay" after him — his name was pronounced ''yan yōsuten'' in Japanese (short version: Yayōsu (耶楊子)) — the Yaesu side of Tokyo Station is also named for him. Yaesu Avenue has a monument dedicated to Jan Joosten and his life after his arrival in Japan on ''De Liefde'' with his shipmate William Adams. Ukiyo-e artist Andō Hiroshige was born in the Yayosu barracks in the Yaesu area in 1797. Places in Yaesu *Tokyo Station *Tokyo Midtown Yaesu * Yaesu underg ...

Family Radio Service
The Family Radio Service (FRS) is a walkie-talkie radio system authorized in the United States since 1996. This personal radio service uses channelized frequencies around 462 and 467 MHz in the ultra high frequency (UHF) band. It does not suffer the interference effects found on citizens' band (CB) at 27 MHz, or the 49 MHz band also used by cordless telephones, toys, and baby monitors. FRS uses frequency modulation (FM) instead of amplitude modulation (AM). Since the UHF band has different radio propagation characteristics, short-range use of FRS may be more predictable than the more powerful license-free radios operating in the HF CB band. Initially proposed by RadioShack in 1994 for use by families, FRS gained consumer popularity due to the lack of monthly fees (unlike cell phones) and being inexpensive to buy the radios. It has also seen significant adoption by business interests, as an unlicensed, low-cost alternative to the business band. New rules issued b ...
