Yaesu BRAND namehttp://en.wikipedia.org/wiki/Yaesu_(brand
It was founded as Yaesu Musen Co., Ltd. (八重洲無線株式会社 Yaesu Musen Kabushiki-gaisha?) in 1959
by Japanese radio amateur Sako Hasegawa, JA1MP in the Tokyo neighborhood of Yaesu.
The initial intent seemed to have been to develop and manufacture commercial and amateur radio transceivers for the Japanese market, but by 1964 there were sales agreements placed in Australia and Germany.
In Europe, the equipment was sold under the Yaesu brand and the Sommerkamp brand.
In 1963 the Swiss firm Sommerkamp imported Yaesu equipment and sold it using their own brand.
In the USA, Yaesu's line of equipment was first imported by Spectronics, Inc. located in Signal Hill, CA, in 1965. Spectronics was founded by William Turner, father of Robert Turner who went on to found EMG, Inc. manufacturer of EMG Pickups for electric guitars. Yaesu became an important presence in the U.S. amateur radio market with the introduction and improvement of its very popular FT-101 line of equipment in the 1970s.
In addition, Yaesu transceivers (e.g. FT-200) were OEM'd (e.g. Tempo One) to Henry Radio in Los Angeles.
In Canada, the same radio was sold as the Yaesu FT-200http://www.yaesu-museum.com/ft-200.htm
Sako Hasegawa (JA1MP) died in 1990 and Jun Hasegawa took over his job as managing director.
Yaesu Musen acquired the STANDARD radio equipment brand from Marantz Japan in 1998, and changed the company name to Vertex Standard Co., Ltd. (株式会社バーテックススタンダード Kabushiki-gaisha Bātekkusu Sutandādo?) in 2000.
In 2007 Motorola announced its intention to purchase 80% of Vertex Standard and form a joint venture with Tokogiken, which would hold the other 20%. This deal was completed in January 2008. The joint venture was dissolved effective January 1, 2012.
The Vertex Standard Land-Mobile Division remains with Motorola (Solutions
The Amateur Radio, Airband and Marine Radio business
was transferred to the new company "Yaesu Musen".
==Moving forward, from 2012, it has yet to be determined who will be manufacturing the Yaesu Musen VHF/UHF equipment that mirrors Vertex Standard Land Mobile business.
