The Kenwood TS-590S ® held its debut at the 2010 Dayton Hamvention. It provides impressive, affordable on the amateur HF and 6 meter bands. Thanks to a receiver down-conversion, narrow roofing filter and dedicated first mixer, the TS-590S has the best dynamic range in its class in handling unwanted adjacent off-frequency signals ¹. The first ever 6 kHz roofing filter BW located directly after the mixer improves the ability of the noise blanker to deal with off-frequency signals. The result is a radio with excellent receive performance, revealing the hidden signals.
Kenwood was first in the amateur market to deploy DSP based AGC IF stage. The TS-590S has taken DSP to the next level. With this new transceiver, a 32-bit DSP is deployed from the stage before the IF and the TS-590S marks a new chapter in the proud history of Kenwood high performance transceivers. The DSP based AGC has been improved to the target signal in the IF passband, and the result is greatly improved characteristics in the band of the IMD which are on par with those that are “upscale” transceivers that cost much more to 160/80/40/20 ¹ ¹ / 15 CW / SSB / FSK.
