Yaesu (brand)

Yaesu, founded as in 1959 by a Japanese radio amateur Sako Hasegawa with call sign JA1MP in the Tokyo neighborhood of Yaesu, is a Japanese brand of commercial and amateur radio equipment.

History

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.

Yaesu's line of equipment was first imported into the US by Spectronics, Inc. located in Signal Hill, California, in 1965. 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, transceivers were OEM'd to Henry Radio in Los Angeles. Spectronics was founded by William Turner, father of Robert Turner who went on to found EMG, Inc. manufacturer of EMG Pickups for electric guitars.

Sako Hasegawa (JA1MP) died in 1993 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 in 2000. In 2007 Motorola announced its intention to purchase 80% of Vertex Standard and form a joint venture with Tokogiken (a privately held Japanese
company controlled by Jun Hasegawa), 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 operates as a wholly-owned subsidiary headquartered in Tokyo, Japan. The Amateur Radio, Airband and Marine Radio business was transferred to the new company "Yaesu Musen".

Digimode "Fusion"

In contrast to analog FM or AM, digital modes using a narrower bandwidth. In the early 2000’s the technology of Minimum-shifting keying (GMSK) emerged in the Amateur radio market as the dominant digital mode, however in 2013 Yaesu introduced “System Fusion”. "System Fusion" is utilizing C4FM 4-level FSK Technology to transmit digital voice and data.

''System Fusion'' provides a simpler interface and a more ham-radio usable set up. The devices recognizes whether the received signal is C4FM digital or conventional FM. Beside telephony System Fusion provides data transfer at full rate with speeds up to 9600 Bits-per-second.

Only Yaesu is producing devices with "System Fusion" mode; competitor ICOM developed based on digital radio protocols developed by the Japan Amateur Radio League the D-STAR mode. Other brands also using DMR and other modes.

* FRG-7700 (HF communications receiver) – An HF receiver for the radio amateur and for the commercial market. It is a metal-cased receiver with a polymer front and it is suitable for reception in the AM, FM, CW and SSB modes. Its frequency coverage is from 150 kHz – 30.0 MHz continuously in 30 switchable band segments. Its frequency readout is available in a traditional analog (dish) mode as well as in a digital display mode. Called a “budget receiver”, the FRG-7700 was released in 1978 as successor to the FRG-7000 and priced at approximately US$450. This type was in production until 1982. The FRG-7700 is a superheterodyne type receiver going up to 48 MHz in the Intermediate Frequency trap, followed by a fully synthesized local oscillators in the 1st and 2nd mixer unit and thus creating a VFO that is reasonably stable after warm-up.
