TS-480HX/TS-480SAT HF/50MHz All-Mode Transceiver
DX Distinction Å\ Creative Concept, Elegant Engineering
Tailor-made for DX' ing, the new TS-480HX HF transceiver raises the bar on portable performance. Despite its compact dimensions, it delivers an astonishing punch: 200W with a DC 13.8V supply. Yet its separate control panel is perfect for base station use. Sharing virtually all the same powerful features is the 100W TS-480SAT, except that it boasts a built-in antenna tuner. Whichever model you choose, you can be sure of enjoying the best of both worlds - first-rate communications at home and on the trail.
This product can be used with the 5MHz frequency band for the US market.

One Rig to Rule Them All Å\ KENWOOD Engineering at Its Finest
As a go-anywhere HF/50MHz all-mode transceiver, KENWOOD's new TS-480HX/SAT is well ahead of the pack when it comes to advanced electronic engineering, convenient features and ease of operation.


High RF power output

Equipped with a twin final section featuring splitter and combiner circuitry, the TS-480HX can provide up to 200 watts RF output (50MHz: 100W) with a DC 13.8V power supply. The TS-480SAT delivers up to 100 watts.

Separate Power Sources

Separate Power Sources

The 200W TS-480HX features two power terminals (DC1, DC2) for separate supply to each half of the twin final section; voltage balance is optimized to ensure stable output. This arrangement allows for use of two PS-53 power supplies or a single 41A power source.

Twin cooling fans

When used for extended periods, the heat build-up inside a compact transceiver can be a serious concern, reducing its working life. But the components in the heavy-duty TS-480HX/SAT are designed to withstand heat. What is more, it is equipped with a die-cast aluminium chassis and twin fans for enhanced cooling efficiency. And since the control panel is separate from the main unit, the fans are able to generate a powerful airflow from front to back. As a result, you can rely on this transceiver to transmit continuously for 30 minutes* without having to power down.
Twin cooling fans
*This figure is supplied for reference purposes only and depends on there being an ambient temperature of 25 C, antenna SWR of 1.2 or less, and nothing to obstruct the air flow generated by the cooling fans.

RX dynamic range

A quad-mixer provides RX dynamic range equivalent to that of the TS-950 class (at 50 kHz separation).

CW support

There is a full range of CW features, including auto tune. When in SSB mode, a simple key-press will switch automatically to CW – very handy for 50MHz operations, especially if combined with slow scan. Another convenient feature is the ability to record three different messages for quick transmission during contests. You can choose between full and semi-break-in; for the former the delay time between key release and active receive mode can be set for between 50ms and 1000ms in 50ms steps. Other CW features include pitch control (400-1000Hz), side tone monitor with 10-step volume setting, an electronic keyer, microphone paddle mode and CW reverse mode.

IF filters (option)
Optionally available for more intense operations are 500Hz and 270Hz band CW narrow IF filters (YF-107C, YF-107CN), as well as a 1.8kHz band SSB narrow IF filter (YF-107SN). Any two of these IF filters can be installed inside the transceiver.
IF filters (option)


Thanks to a 16-bit digital signal processor offering double-precision arithmetic operations (equivalent to 32-bit processing), a 100MHz clock and 16-bit A/D & D/A converters, the TS-480HX/SAT offers many powerful features. AF DIGITAL SIGNAL PROCESSING (TX/RX)

Digital noise limiter (DNL)
With three level settings, the DNL is highly effective in removing even the pulse noise that cannot be eliminated with conventional analogue circuitry and noise blankers. For extra clarity, however, it can be used in conjunction with a noise blanker, which removes pulse noise at the IF stage.
Digital noise limiter (DNL)

Beat cancel (SSB/AM only)
DSP will also cancel out multiple beats falling within the AF filter range. Choose BC1 to remove weak and/or continuous beat interference, or BC2 to handle intermittent beat, like that of a CW signal. Beat cancel (SSB/AM only)

Noise reduction
NR1 is a line enhanced filter with 10 level settings (including auto) – great for extracting a target signal. A good choice for CW operations is NR2(SPAC), adjustable in 2ms increments (2~20ms); it can suppress noise at the same frequency as the target signal, allowing it to pull a weak target signal out from the surrounding noise.
Noise reduction

TX/RX equalizer

The equalizer offers flat (default), high boost (2 types), Formant pass, bass boost (2 types), conventional and user* settings, separately for transmit and receive.
*Configurable using the ARCP-480 radio control program.

AF filters
Slope tune can be used to move the target signal away from noise using hi-cut and low-cut filters (SSB, FM and AM), while Width allows adjustment of the passband to avoid adjacent noise (CW/FSK).
AF filters

TX filter

Audio quality during transmit can be adjusted to suit by switching between two passband settings (500-2500Hz and the default 300-2700Hz).

Speech processor

Available for SSB, FM and AM transmission, the speech processor enhances the clarity of messages for the receiving station. Input/output levels can be finely adjusted (0~100).

CW auto tune

This feature uses DSP to automatically zero in on a target frequency during CW operations. It is also RIT compatible.


Built-in automatic antenna tuner(TS-480SAT)
The automatic antenna tuner inside the TS-480SAT – with presets for quick band changes – covers all amateur bands 1.8MHz to 54MHz. Built-in automatic antenna tuner(TS-480SAT)

Emphasis on portability
Outdoor use is facilitated by DC 13.8V operation and compact dimensions: the 3.2kg main unit measures 179mm (W) x 61mm (H) x 258mm (D)*, while the 0.5kg control panel is 180mm (W) x 75mm (H) x 37mm (D)*.
*Projections not included.

Separate LCD control panel with speaker
The large, standalone LCD control panel – featuring its own 6.6cm speaker (2W max. output) – can be freely positioned up to 4 metres from the main unit. The supplied tabletop panel bracket is convenient when using the transceiver at home on a desk, while the mobile panel bracket is ideal for mounting in a car. The panel can be snapped into place or removed from a bracket instantly. It also features 34 keys, each with backlighting to enhance operating ease. Separate LCD control panel with speaker

PSK31 compatible (SSB/FM)

The TS-480HX/SAT can be connected directly to a computer for the increasingly popular PSK31 mode. It also offers the following convenient features:
Separate adjustment of AF input/output levels (10 steps)
Choice of centre frequency (1000Hz or 1500Hz)
Adjustable AF DSP filter bandwidth (7 steps)
Selectable CW narrow IF filters (if installed)
TX with VOX function (no need for a PTT control line)

Voice guide & storage unit (option)

The VGS-1 voice guide and storage unit can serve two important roles: vocal confirmation of frequency, key operation, etc., and recording/playback of messages received by the transceiver. A total of 90 seconds (3 x 30 seconds) can be recorded and stored in Flash ROM for playback and transmission. Additionally, a convenient constant record function means you can always play back the last 30 seconds of reception for confirmation.
