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 ...
In recent years, Kenwood and Yaesu have both included the 1.25-meter band in some of their multiband handheld transceivers. The Kenwood TH-F6A and TH-D74A; the Yaesu VX-6R, VX-7R and VX-8R (United States and Canada version) include coverage of the 1.25-meter band in addition to the more popular 2-meter and 70-centimeter bands.
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 ...
Once the schematic has been made, it is converted into a layout that can be fabricated onto a printed circuit board (PCB). Schematic-driven layout starts with the process of schematic capture. The result is what is known as a rat's nest. The rat's nest is a jumble of wires (lines) criss-crossing each other to their destination nodes.
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.
Motorola T5320 FRS handheld radio. The Family Radio Service (FRS) is an improved 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.
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]
Basic schematic for matching R 1 to R 2 with an L pad. R 1 > R 2, however, either R 1 or R 2 may be the source and the other the load. One of X 1 or X 2 must be an inductor and the other must be a capacitor. L networks for narrowband matching a source or load impedance Z to a transmission line with characteristic impedance Z 0.
