Swift 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 user-friendly refinements.

TS-950SDX in detail:
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)
- 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 reliability.
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
- Independent IF & AF circuits for main & sub receivers
- M/S (main/sub) select for operating sub receiver with main tuning knob
- TF-SET (transmit frequency set) and "delta" F function
- Independent CW filter (500 Hz) and S meter for sub receiver
- 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 available.
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 memory.
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
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 RIT/XIT control.
