The Baofeng UV-5R is a hand-held radio that has been marketed in the United States[6] and was produced since 2012.[7] It has been used in a number of projects involving radios.[8][9] It is described as a popular inexpensive model.[6]
The UV-5R is designed to transmit on the 2 meter band between 136 and 174 MHz and on the 70 cm band between 400 and 520 MHz. (480 MHz to 520 MHz is not available in the UK to comply with Ofcom regulations and are blocked by the manufacturer). Features include CTCSS and duplex operation for use with local repeaters, dual watch and dual reception, an LED flashlight, voice prompts in either English or Chinese and programmable LED lighting for the LCD display.
Illegal marketing and distribution in the United States
The FCC cited the Houston, Texas based importer Amcrest Industries which owns and operates Baofeng radio US for illegally marketing UV-5R, "capable of operating outside the scope of its equipment authorization,” the FCC Citation said, which is outside of its Part 90 authorization granted. The FCC asserts Amcrest marketed "UV-5R-series FM hand-held radios capable of transmitting on “restricted frequencies." "Marketing a device that is "capable of operating outside the scope of its equipment authorization,” is not allowed.[6]
Among the product lines are the "TS" series of HF transceivers which cover the HF ("high frequency") bands, from 1.8 to 50 MHz. These transceivers include the TS-820S, the TS-590S, the TS-850S, the TS-430S.
Other series include the 100, 500, and the 2000 series. Kenwood also offers a "B" model, which is a transceiver without display or controls and is completely controlled by a remote computer or a separate control unit.
Radios with built-in digital data modes and modems (for APRS)
The Kenwood TS-2000 is an amateur radiotransceiver 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 also has built-in 23 centimeters band capability option. Kenwood discontinued production of the TS-2000 in September, 2018.[27]
The TS-2000 was marketed as a feature-rich transceiver. As an "all-band" transceiver, the TS-2000 offers a maximum power output of 100 watts on the HF, 6 meters, and 2 meters bands, 50 watts on 70 centimeters, and, with the TS-2000X or the optional UT-20, 10 watts on the 1.2 GHz or 23 centimeters band. The (American version) radio's main receiver covers 30 kHz through 60 MHz, 142 MHz through 152 MHz, and 420 through 450 MHz (plus 1240 through 1300 MHz with the "X" model). The sub-receiver tunes between 118 and 174 MHz, and from 220 to 512 MHz (VFO ranges).[28]
The radio's main receiver uses DSP at the IF level, so a very flexible selection of bandwidths are available without the purchase of mechanical filters, as was necessary on past radios.
It features backlit keys, a built-in TNC for receiving DX Packet Cluster information, and the Sky Command II+ system (found on the K-Model), which allows for remote control of the transceiver using Kenwood's TH-D7A handheld or TM-D700A mobile radio.
The Kenwood TS-820S is a model of amateur radiotransceiver produced primarily by the Kenwood Corporation from the late 1970s into the 1980s; some were produced by Trio Electronics before Kenwood's 1986 name change). The transceiver's predecessor was the TS-520, which began production a year earlier. The TS-820S was the second of three hybrid (including vacuum tubes and semiconductors) models produced by Kenwood during the 1970s and 1980s,[32] and was noted for its quality. Its functionality and new hybrid technology made it one of the most popular transceivers marketed to amateurs in the late 1970s and early 1980s. The TS-820S has a built-in power supply, so it can be plugged directly into a 120 V wall outlet.
The TS-820 did not have an LED frequency counter, but was otherwise identical to the 820S.[33] The TS-820S was the most sophisticated (and common) variant.[33] The TS-820X, unavailable in the United States, was primarily produced in Japan.
The transceiver can transmit and receive on the HF 10-, 15-, 20-, 40-, 80- and 160-meter bands,[33] and can receive WWV and WWVH on 15 MHz. It can use SSB, FSK and CW on all bands.[33] The TS-820S' power consumption is 57 watts (with heaters on) when receiving and 292 watts when transmitting. The transceiver's peak envelope power output on SSB and CW is about 100 watts, and about 60 watts on FSK. Its tubes are tuned manually, using the transceiver's drive, plate and load controls.
The Yaesu FT-857 is one of the smallest MF/HF/VHF/UHF multimode general-coverage amateur radiotransceivers.[45] The set is built by the Japanese Vertex Standard Corporation and is sold under the Yaesu brand.
[46] The FT-857 is developed on the FT-897 and MARK-V FT-1000MP transceivers.[45]
These are low power transceivers primarily used by Amateur radio operators for QRP (low power) operation. They are available as commercial products, built from kits or homebrewed from published plans.
