performance and surgical precision are second nature to the
TS-950SDX. Quality engineering blends aesthetic simplicity of
form with a wide range of advanced features -- such as the
built-in DSP (digital signal processor) and MOS FET final
section. The result is exceptional transmission signal purity
and first-class audio quality -- a benchmark for HF
communications. And operating ease is just as impressive,
thanks to the convenient menu system and many other
at a glance:

Digital signal processor (DSP)
The digital accuracy and reliability offered by the built-in
DSP, for both TX and RX, translate into an unprecedented
advantage in HF communications.
- Outstanding performance
Carrier suppression is more than 50 dB, and
unwanted-sideband suppression is also greater than 50 dB.
- Digital AF filters
15 LPFs for SSB and CW modes (with cutoff frequencies
ranging from 600 Hz to 6 kHz), and 3 BPFs for FSK use (with
a central frequency of 2200 Hz) are menu-selectable.
- Digital filtering eliminates key clicks
- Superior FSK transmission circuit
The data control oscillator provides rapid switching for
the cleanest FSK signal. The operator can choose 170, 200,
425 or 850 Hz FSK shift.
- Selectable sound quality
To ensure high-quality sound, there are 4 low-cut filters
plus a through position, and 4 high-cut filters.
Dedicated Power MOS FET (MRF 150MP) final section
The TS-950SDX was the first amateur radio transceiver to
feature an FET final section. Excellent linearity results in
greatly improved transmitter performance and enhanced
Dual-frequency receive capability
For maximum convenience when operating split frequencies, the
TS-950SDX can simultaneously receive two frequencies, which
can be within 1 MHz of each other.
- Independent IF & AF circuits for main & sub
- M/S (main/sub) select for operating sub receiver with
main tuning knob
- TF-SET (transmit frequency set) and "delta" F
- Independent CW filter (500 Hz) and S meter for sub
- Simultaneous, independent monitoring
- Using an external speaker or headphones, main and sub
receivers can be monitored simultaneously yet
independently; monaural and mixed monitoring are also
Powerful menu system
Rapid, user-friendly access to the many features and functions
of the TS-950SDX is provided by the menu system. This includes
32 menus for power-on settings, and a further 29 menus for use
during transceiver operation.
The Quick Memory feature allows for stacking and recalling
frequency, mode and filter information on the fly. The 5
channels reserved for this purpose are independent of main
Automatic antenna tuner
Built into the TS-950SDX, for maximum operator convenience, is
a completely automatic antenna tuner (compatible with
impedances of between 20 and 150 ohms), controlled by a
microprocessor preprogrammed to rapidly tune for minimum SWR.
First-rate receiver performance and sensitivity
- Superb frequency stability
A TCXO (temperature-compensated crystal oscillator) and
microprocessor-controlled digital PLL, DDS circuits
control the frequency in 1 Hz steps. Consequently, the
reference frequency (20 MHz) is accurate to within ±0.5
ppm between -10 degrees and +50 degrees C.
- AIP system
AIP (Advanced Intercept Point) is an exclusive circuit
design that provides superior dynamic range (when AIP is
selected). The use of two selective RF amplifiers results
in a significantly reduced noise floor level.
- 15 band-pass filters
The RF amplifier section and 15 band-pass filters --
including 10 BPFs for amateur bands -- together offer
outstanding two-signal characteristics.
- Selectable IF filters with memory
Innovative interference reduction
- SSB IF slope tuning
For LSB and USB modes, independent high-cut and low-cut
controls permit the operator to select the ideal IF
passband width quickly and easily.
- IF VBT & AF VBT
With the variable-bandwidth tuning control, passband width
can be adjusted without affecting the centre frequency. In
CW, FSK and AM modes, the IF VBT control allows the
operator to avoid interfering signals while maintaining
optimal signal-to-noise ratio.
- High-precision IF notch filter
Available for all modes except FM, the tunable IF notch
filter provides approximately 45 dB of attenuation in a
very narrow frequency range.
- Dual-mode noise blanker plus noise-select function
The blanker offers two modes -- NB-1 ("pulse")
and NB-2 (longer duration noise) -- and can be tailored to
match specific noise and signal level conditions. Also, by
dedicating the sub receiver to noise detection and using
its blanking pulse to blank the main receiver, the
operator can soon determine the optimum setting.
High-performance CW functions
- Full break-in and semi break-in
- Reverse mode
In reverse mode the pitch of interference competing with
the CW signal is reversed, so the operator can approach
the target from either side.
- Variable pitch control
Using the pitch control, CW pitch frequency can be varied
between 400 Hz and 1000 Hz in 20 Hz steps. Current pitch
frequency can be checked using the menu system.
100 memory channels
The TS-950SDX is equipped with channels 0-89 for independent
storing of transmit and receive parameters such as frequency,
mode, filter setting, auto-tuner and tone frequency. Memory
channels 90-99 can be used to establish the upper and lower
limits for the programmable band marker.
Any or all of the memory channels may be scanned, with
selected channels skipped using the programmable memory
channel lock-out function. The TS-950SDX can scan up to 10
groups automatically within the limits specified by the
programmable band marker, and can also scan sub-receive
frequencies. Scan speed can be varied continuously using the
