DESCRIPTION OF COMPONENTS. Kenwood TS-2000 X
The TS-2000 X is an all-mode multi-band transceiver that incorporates an IF/AF DSP for satellite communication. It also features an independent FM/AM sub-receiver for the VHF and UHF bands. The main band side has an independent front end for each of the HF, 50MHz, 144MHz, 430MHz and 1.2GHz bands. The sub-band receiver is not used during satellite operation, but it can receive signals while the main band receiver is sending a signal. In addition to the standard features of a transceiver, the TS-2000 X also includes features such as a noise blanker, a digital IF filter, and a digital AGC. It also has a speaker separation function that allows you to output the audio to two separate speakers or headphones. The TS-2000 X is a powerful and versatile transceiver that is suitable for a wide variety of applications, including satellite communication, HF and VHF/UHF operation, and contesting.
