The TS-590S marks a bold new chapter in Kenwood’s proud history of manufacturing high-performance transceivers. Featuring a narrow-band Roofing Filter the TS-590S significantly reduces interference from unwanted signals that would be hidden to lesser rigs. With IF AGC based on advanced DSP technology, Kenwood has essentially redefined HF performance. Built to satisfy the most demanding DX’er, this high-performance HF transceiver takes Amateur Radio to the next level continuing the Kenwood tradition of operating ease and rugged reliability.
