[. . . ] INSTRUCTION MANUAL ALL MODE MULTI-BAND TRANSCEIVER TS-2000 TS-2000X TS-B2000 KENWOOD CORPORATION B62-1221-20 (K) 09 08 07 06 05 04 03 02 THANK YOU THANK YOU Thank you for choosing this KENWOOD TS-2000(X)/ TS-B2000 transceiver. It has been developed by a team of engineers determined to continue the tradition of excellence and innovation in KENWOOD transceivers. This transceiver features dual Digital Signal Processing (DSP) units to process IF and AF signals. By taking maximum advantage of DSP technology, the TS-2000(X)/ TS-B2000 gives you enhanced interference reduction capabilities and improves the quality of audio that you transmit without installing additional analog filters. [. . . ] Changing the filter bandwidth does not affect the current receive frequency. Note: x The receive filter bandwidth can be changed only on the main transceiver. x The IF DSP filter is not available in FM mode. s CW/ FSK Modes 1 Press [CW/ FSK/ REV] to select CW or FSK mode. 3 Turn the LO/ WIDTH control clockwise to increase (wide) the bandwidth, or counterclockwise to decrease (narrow) the bandwidth. s SSB/ FM/ AM Modes 1 Select SSB, FM, or AM mode. 3 Turn the LO/ WIDTH control clockwise to raise the low cut-off frequency, or counterclockwise to lower the low cut-off frequency. LO/ WIDTH f Interfering signal Desired signal Interfering signal Mode f Turn the HI/ SHIFT control clockwise to raise the high cut-off frequency, or counterclockwise to lower the high cut-off frequency. HI/ SHIFT f CW Bandwidth Selections (Hz) Default (Hz) 600 1500 50, 80, 100, 150, 200, 300, 400, 500, 600, 1000, 2000 FSK 250, 500, 1000, 1500 4 As for CW, you can further adjust the shift frequency for passband. Turn the HI/ SHIFT control to adjust the shift frequency from 400 to 1000 Hz in steps of 50 Hz. 5 To return the display to the current operating mode, press [DISP]. f Adjust LO/ WIDTH Frequency Selections (Hz) 0, 50, 100, 200, 300, 400, 500, 600, 700, 800, 900, 1000 1400, 1600, 1800, 2000, 2200, 2400, 2600, 2800, 3000, 3400, 4000, 5000 55 HI/ SHIFT 12 REJECTING INTERFERENCE NOTCH FILTER (SSB) Auto Notch filter automatically locates and attenuates any single interfering tone within the receive pass band. This function operates digitally at the IF filter level, hence it can affect your S-meter reading and may also affect (slightly attenuate) your desired signal. However, controlling the AGC level by notching out the strong interfering beat signals could bring up the desired SSB signal that is covered by the interfering beat signal. If the interfering tone is weak, you may find that Beat Cancel eliminates them more effectively. Receive pass band Interfering tones MANUAL BEAT CANCEL (ALL MODES) Press [FUNC], [B. C. / MANUAL], then turn the MANUAL BC control to select the single Beat Cancel frequency manually. Turn the control clockwise to select a higher frequency and counterclockwise to select a lower frequency. Since the DSP Beat Cancel processes the incoming signals at the AF stage, strong beat signals may control the AGC, then weaken the target signal level. In this case, use the Auto Notch Filter instead, to remove the beat signal from the IF passband filter. Note: While adjusting the MANUAL BC control, the transceiver clicks. This is not a malfunction. Desired signal Before After NOISE REDUCTION (N. R. 2: SSB/ CW/ FSK/ AM) This transceiver provides two types of Noise Reduction functions (1 and 2) for reducing random noise which interferes with the desired signal. Trying them both is the easiest way to judge which function works more effectively under the current conditions. Normally, select Noise Reduction 1 (Line Enhanced) in SSB mode and Noise Reduction 2 (SPAC) in CW mode. Press [N. R. / LEVEL] to toggle between Noise Reduction 1, Noise Reduction 2, and OFF. " or " " appears, depending on which " function is selected. Press [A. N. / LEVEL] to toggle the Auto Notch Filter ON and OFF. If the interfering beat signals change the tone frequency randomly, you can adjust the Auto Notch level. Press [FUNC], [A. N. / LEVEL] to access the Auto Notch level adjustment, then turn the MULTI/ CH control to select the level from FIX, and 1 to 4.
