COMPUTER (Requires optional IF-
232C)
Control with a personal computer is possible with the
optional IF-232C interface. For more information,
refer to the manuals provided with the interface.

(Requires the use of the optional VS-2 Voice
Synthesizer)
When the VOICE key is pressed the transceiver will
audibly announce the operating frequency.
When the function is set when the power is switched
on, the transceiver will audibly announce the menu
number and its contents.

4-17. DIGITAL MODULATION FUNCTION
[The Digital Signal Processor DSP-
100 (option) is required. ]
SSB, CW, AM, or FSK modulation and detection in
SSB receive mode are done by the 16-bit A/D and
D/A converters and DSP (digital signal processor).
(1)Features of each Mode
@SSB mode
Modulation of higher quality than a usual SSB
mode is obtained through modulation by the 10th
phase-shift network that digitally processes
signals.
(@CW mode
Excellent characteristics are obtained through
digital form-restoration of the wave shape.
@AM mode
Low-distortion modulation with excellent amplitude
and group delay characteristics is obtained
through digital modulation and by using the 84th
FIR filter.
@FSK mode
Excellent, low-distortion modulation is obtained
through FSK modulation with continuous phasing
after the digital form-restoration.
@©SSB, CW, and FSK mode (receive)
Received SSB, CW, and FSK signals are
detected by the DSP.
(2)Operation
@Microphone gain adjustment
When the DSP-100 TX switch is on, the microphone
gain in the SSB and AM modes is adjusted with the
DSP-100 MIC GAIN control so that the TS-850 ALC
meter pointer does not exceed the ALC range.
@Carrier level adjustment
When the DSP-100 TX switch is on, the carrier level
in the CW, FM, AM, and FSK modes is adjusted with
the DSP-100 CAR LEVEL control. For the level
setting, see Section 4-4, CW __ operation
(transmission), Section 4-5, FM __ operation
(transmission), Section 4-6, AM __ operation
(transmission) and Section 4-7, FSK operation
(transmission).
Note
When the DSP-100 TX switch is off or the power
is off, the DSP-100 MIC GAIN and CAR LEVEL
controls do not work. Use the TS-850S control.
