TS-2000 

The Kenwood TS-2000 is an amateur radio transceiver manufactured by the Kenwood Corporation. 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 and 33 centimeters bands, and the "X" model also has built-in 23 centimeters band capability option. Kenwood discontinued production of the TS-2000 in September, 2018.

Variations 
 TS-2000, the standard base station model, with the regional versions
 K-Type for the Americas;
 E-Type for Europe;
 E2-Type for Spain;
 TS-2000X, same as the above with the addition 1.2 GHz (23 cm band) capability;
 TS-B2000, a sleek "black box" unit requiring a computer or an optional mobile control panel for control
 TS-2000LE, limited production TS-2000 with a black finish to celebrate Kenwood's 60th Anniversary

Features 
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).

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.

Firmware 
Kenwood provides a firmware Update, Memory Control Program MCP-2000, and Radio Control Program ARCP-2000.

TS-820S 

The Kenwood TS-820S is a model of amateur radio transceiver 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, 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.

Variants 

The TS-820 did not have an LED frequency counter, but was otherwise identical to the 820S. The TS-820S was the most sophisticated (and common) variant. The TS-820X, unavailable in the United States, was primarily produced in Japan.

Functions 
The transceiver can transmit and receive on the HF 10-, 15-, 20-, 40-, 80- and 160-meter bands, and can receive WWV and WWVH on 15 MHz. It can use SSB, FSK and CW on all bands. 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.
