EASY OPERATION

Kenwood’s TS-570D/S(G) with Advanced Technology Upgrade

16-bit AF-stage DSP delivers superb audio quality on both transmit and receive

Adjustable transmit sound quality and NR1 Noise Reduction System

Digital filtering with 3 new CW DSP filters give you the edge when conditions are tough Compact enough for mobiling, yet large enough to build a station around Compatible with the Kenwood Sky Command System, offering the convenience of handheld remote control.

High-end radio technology doesn’t mean

ahigh-end budget anymore — Kenwood delivers it today with the all-new TS-570D(G) and TS-570S(G) (HF+6m). With 16-bit DSP technology, untouchable digital filtering, heavy-duty transmitter design, a Central Frequency Control System for near-perfect stability, and a large LCD display section coupled with an ergonomically-optimized human interface, the TS-570D/S(G) provides a clean and powerful operating experience. All of this wrapped up in a compact and efficient package makes the TS-570D/S(G) the perfect choice for home or mobiling in your car, RV or boat.

AF-stage Digital Signal Processing

Interference Reduction

AF-stage digital signal processing provides extensive control over received signals by identifying and filtering interference using digital algorithms. This results in interference reduction capabilities simply not attainable with analog designs. In addition, the new NR1 system is operator-adjustable in 9-step increments, or it can be assigned to track input signal strength automatically. Both the NR1 and NR2 settings now track when changing mode groups

(eg. SSB/AM/FM to CW/FSK). The new Dual Selectable Beat

Cancel (BC) function also works against inter- mittent beat interference (except in CW mode).

In SSB/AM/FM modes you can select a Hi/Low cut DSP slope tune using up to 441 possible combinations. In CW and FSK, the DSP acts as a VBT (Variable Band Tuning) that alters passband width, for rejection of nearby signals. The super-narrow CW filter (50 Hz) enables effective filtering even during very crowded conditions, with its center frequency tied to the pitch frequency so they track together. The G model also incorporates 3 new CW DSP filters: 80 Hz, 150 Hz, 500 Hz, for a total of 11 user-selectable filters. You can now also use the “One-touch” DSP filter wide mode to instantly check band conditions when oper- ating in narrow mode.

When used in conjunc- tion with the equalizer, the CW filter reduces ringing to almost undetectable levels.

There are also 3 optional fil-

ters that can be easily installed (one at a time) to acquire various IF filter bandwidth selections (see optional accessories). The DSP also pro- vides 2 types of noise reduction — the Line Enhancer Method (NR1) for SSB/AM and the

SPAC (Speech Processing by Auto Correlation) Method (NR2) for CW. The Line Enhancer

In addition, the DSP Beat Cancel function suppresses multiple beats on SSB, FM and AM immediately upon detection, great for 40-meter broadcast station carriers.
