10、F filter shapes: Medium/ Soft/Sharp. Switching is also possible for post-demodulation voice- audio between 3 kinds of AF filter passbands: Medium/Wide/ Narrow. Combinations of these settings can adjust the sharpness of the demodulation signal. Audio peak filter This is a narrow bandwidth peak filter

11、 operated during receive in CW mode. When intelligibility is low due to noise, it has the effect of floating the target signal and increasing intelligibility. The central frequency is linked to the pitch frequency, and can be given a maximum peak gain of +6dB. Notch filter A notch filter that operat

12、es in the IF stage. By eliminating strong interfering signals, it allows weak target signals to stand out. Damping range can be switched between three levels: Narrow/Middle/Wide, enabling operation to match interference conditions. Noise reduction function (NR1/NR2) In addition to conventional NR1/N

13、R2 noise reduction, NR1 comes equipped with noise reduction using spectral-subtraction, which focusses on noise reduction in voice-audio system modes. The optimum noise reduction method is applied for each receive mode. Noise blanker A noise blanker reduces crackling, pulse-type noise. The TS-890S i

14、ncludes two kinds of noise blankers: NB1, which processes analogue signals, and NB2, which carries out digital processing in the IF stage using DSP. Furthermore, selection of NB2 can be made from two kinds of NB with different operating principles. Either NB1 or NB2 can be used depending on noise co

15、nditions, or both can be used simultaneously. Beat cancel function (BC1/BC2) While a notch filter (IF stage) is effective for a single strong beat, beat cancelling (AF stage) shows results on multiple, comparatively weak beats. BC1 is effective on weak beats and continuous beats, while BC2 is effect

20、at 14.1 MHz The TS-890S uses 8.248MHz 1st IF frequency down conversion for its receive signal system in order to continue the adjacent interference signal exclusion legacy refined in the TS-990S. This means you can use narrow bandwidth crystal filters with passband widths of 500Hz or 270Hz (optional

21、 YG-82CN-1) as roofing filters to achieve strong exclusion of unnecessary adjacent signals. The 1st mixer is the H-mode mixer also carried by the TS-990S. Conversion characteristics have been improved with fine-tuning of input/output matching as well the device used. The configuration of the band sc

22、ope receiver has changed from the superheterodyne system used in the TS-990S to 1st IF sampling using an A/D converter (14bit/39MHz), and FPGA digital down conversion. This means a change in scanning method from step FFT to FFT, achieving high- speed updates to the display irrespective of span setti

23、ngs. Interference signal exclusion is not determined by roofing filters and signal system devices alone. The TS-890S has taken the VCO division of the TS-990S and developed it further, combining a VCO device with high C/N in the gigahertz band and a reference oscillation circuit with superior adjace

24、nt C/N to deliver C/N characteristics unattainable in conventional units. Passband frequency range expansion through LOW-CUT/HI-CUT, WIDTH/SHIFT. Interfering signal removal and desired audio-quality adjustment, as well as more convenient operation in digital mode. Operation with LOW-CUT / HI-CUT in

25、SSB/AM/FM mode, WIDTH/ SHIFT in CW mode, and WIDTH function in FSK/PSK mode. Change to WIDTH/SHIFT operation as in CW mode also possible in SSB/SSB- DATA mode. Selection of roofing filter (270Hz*/500Hz/2.7kHz/6kHz/1 5kHz) can be automatic to match IF filter passband width or manual to selectable fre

26、quencies. (*270Hz when option mounted) A variety of functions are realized through 32-bit floating-point DSP technology inherited from the TS-990S, including modulation/demodulation in all modes, IF filter, IF-AGC, and removal of interfering signals. Popular for its non-tiring and great-quality audi

33、 in the TS-990S. In addition to basic information including frequency, mode, and S-meter, the band scope and audio scope are also displayed. The TS-890S also displays further improvements in visibility and operability in tough usage scenarios such as competitions. The popular sub-scope from the TS-9

34、90S is carried as a filter scope display. You can confirm receive filter selection status, roofing filter bandwidth, IF filter passband information, receive for ex-audio spectrum, CW pitch frequency, and notch frequency all concentrated in one location. The final-stage amplifier device is a Mitsubis

35、hi-made MOSFET RD100HHF1(Pch 176.5W) operating in push-pull. A MOSFET RD16HHF1 has been used for the drive amp, and a MOSFET RD06HHF1 for the pre-drive amp. Inter-stage matching and fine-tuning delivers superior transmit IMD even for a 13.8V final circuit, enabling operation with a clean and low-dis

36、tortion signal. The unit employs a twin cooling fan system that uses a pair of 80 x 80 mm fans. Using two fans provides sufficient air flow at low rpm, making for superior quietness. The quietness level for the fans when operating has been improved by more than 5dB compared to our conventional model

37、s. Furthermore, the use of an aluminum die-cast chassis combined with a large heat sink makes for a heavy-duty design sufficiently capable of withstanding the tough conditions typical of contests or long hours of hard operation. A variety of linear amp connections have been taken into account, inclu

38、ding self-made ones, and independent settings for various kinds of control at HF/50MHz bands are possible. Possible settings include: linear amp ON/OFF, transmission control (H active, L active), transmission delay ON/OFF, transmission delay time (CW/FSK/PSK) and (SSB/AM/FM), internal relay control,

39、 and external ALC threshold voltage adjustment. The antenna tuner is a preset type also operable during receive and covering amateur bands from 1.8MHz50MHz. High-speed operation and the proven relay method enable rapid QSY through instantaneous band changing. The menu can be used to set an ON/OFF me

Equipped with a TCXO (temperature compensated crystal oscillator) requiring no warm-up as standard, high stability of 0.1ppm has been obtained in a wide temperature range covering from 32F122F.

AUTO SCROLL MODE In addition to conventional CENTER MODE and FIXED MODE, the unit comes equipped with an AUTO SCROLL M

44、ODE. While in FIXED MODE, if the receive frequency goes over the scope edge, then auto- scroll will engage for half a screen width. Furthermore, with the EXPAND function turned on, the screen to be displayed next can be drawn in advance*. Also, with the SHIFT function, the receive marker can be set

45、in the desired position on the vertical grid, which is convenient when displaying a non-receive frequency as the center display, such as for pileups during splits. *: Effective in spans under 200kHz. Image becomes slightly coarse when expanded. CENTER MODE When changing the receive frequency in CENT

46、ER MODE, there are many units that display a bright line that flows obliquely over the waterfall, but with the TS-890S, the bright line remains straight and enables tuning operation*. Switching to the follow display is also possible via the menu. *: During straight display, the waterfall bright line

47、 temporarily stops and undergoes parallel displacement. Image becomes slightly coarse when expanded. The TS-890S has improved operability of the reference level focusing on the visibility of the waterfall. Through optimization of each span, readjustment is mostly unnecessary when switching between t

FIXED MODE FIXED MODE allows you to switch between three kinds of display ranges with a single touch of the panel

49、screen. The initial value is preset based on the band plan, but this can be easily adjusted to a desired scope. With the spectrum scope and waterfall screen display, the analogue meter is simultaneously displayed. The popular sub-scope display from the TS-990S has been incorporated as a filter-scope display Auto-scroll operation (span 10 kHz, EXPAND ON) On the current screen (screen 2), if the frequency is changed to go over the top end of screen 2, it will automatically change to screen 3, and if it goes over the bottom end of
