The Kenwood TS-2000 is an amateur radio transceiver manufactured by the Kenwood Corporation. [ 24 ] [ 25 ] [ 26 ] Introduced in the year 2000, the radio was known for its "all-in-one" functionality. It can transmit on all amateur radio bands between 160 meters and 70 centimeters , with the exception of the 1.25 meters band, and the "X" model ...
2019: Launch of heavy-duty, dual PTT ProTalk TK-3701D hand-portable digital dPMR 446 radio. 2019: Launch of low-tier, FM analogue plus digital DMR/NXDN capable NX-1000 Series radios. 2022: JVCKENWOOD moves from the First Section of the Tokyo Stock Exchange to the Prime Market due to a revision of the Tokyo Stock Exchange 's market classification.
Accuphase was founded by former Kenwood engineer Jiro Kasuga in late 1972. [1] Kasuga was not happy with the views of Kenwood relating to the follower of their High-End Supreme 1 unit (1967). He hired some engineers from other prominent brands (Marantz, Luxman) and started Kensonic, with Kenwood as a part owner. Some other connections in the ...
In electronics, power amplifier classes are letter symbols applied to different power amplifier types. The class gives a broad indication of an amplifier 's characteristics and performance. The first three classes are related to the time period that the active amplifier device is passing current, expressed as a fraction of the period of a ...
X-1000 Series Integrated Amplifier; X-200 Series Integrated Amplifier; X-100 Series Integrated Amplifier; The Fisher was also used on Fisher's early US made solid-state equipment, such as the model 210 receiver. Fisher FM tuners and receivers often used similar designs and components thus allowing parts to be swapped between various models.
Additionally, the 6V6 had applications in portable battery-operated radios. [ 6 ] The data sheet information supplied by the tube manufacturers' design-centers list the typical operation of an audio output stage for a single 6V6 as producing about 5W of continuous power, and a push-pull-pair about 14W.
Like a standard operational amplifier, the OTA also has a high impedance differential input stage and may be used with negative feedback. [3] But the OTA differs in that: The OTA outputs a current while a standard operational amplifier outputs a voltage. The OTA is usually used "open-loop"; without negative feedback in linear applications.
The SCR-536 is often considered the first of modern hand-held, self-contained, "handie talkie" transceivers (two-way radios). It was developed in 1940 by a team led by Don Mitchell, chief engineer for Galvin Manufacturing (now Motorola Solutions) and was the first true hand-held unit to see widespread use. [1]
