A remodeling of the AGC circuitry has realized superb AGC performance covering from small to large inputs. This series features all of the IF DSP AGC technology developed with the TS-990S. Non-tiring even in long contests, is determined by IF AGC control based on unique DSP algorithms. It would be no exaggeration to say that Kenwood's receive audio, which enjoys a reputation for being

Advanced AGC control through digital signal processing from the IF stage onward *3: The American Radio Relay League (ARRL) is the national association for amateur radio.Ģ. Note: TS-590S measurement values from QST® MayĢ011 PRODUCT REVIEW Kenwood TS-590S HF and 6 Meter Transceiver published by ARRL (reprinted with permission of ARRL) It can be seen that the TS-590SG achieves virtually flat characteristics even in the 3rd Order Dynamic Range measurement method implemented by ARRL*3. For example, at the point where separation is 10kHz, the interference signals are 14.03MHz and 14.04MHz. This graph shows what happens when the frequencies of two interference signals for measuring the dynamic range are converted from +2kHz to +20kHz from the reception frequency. *2: Down conversion is selected automatically when receiving in CW/ FSK/ SSB modes if the final passband is 2.7 kHz or less. You can capture a clear signal even in reception conditions where strong adjacent interfering signals become Even when an interfering signal approaches the reception frequency, a virtually flat dynamic range is maintained. Included as standard directly after the 1st Mixer and Post Amp that compensates for conversion loss is a BW 500 Hz and 2.7 kHz 6-pole MCF, which determines adjacent receptivity realizing superb dynamic range performance that was not possible using up conversion.

Equipped with 500 Hz/ 2.7 kHz Roofing Filter as standardġst IF frequency (11.374 MHz) down conversion*2 is employed when receiving on 15, 20, 40, 80 or 160 meter bands. TS-590SG Incremental changes help performance and function to evolveġ. Technology has moved on, so now it is a pleasure to announce the updated TS-590SG model, which replaces the TS-590S in production.

Four years ago we launched our best-selling TS-590S transceiver into the mid-range HF market.
