K4 TRANSCEIVER
High-Performance Direct-Sampling SDR
Our new K4 doesn’t just harness the latest technology: it blends new tech with a classic user interface to create a transceiver that’s more than the sum of its parts. One that’s sophisticated, yet civilized.
Like you, we’ve witnessed the recent revolution in direct sampling and SDRs. But rather than rush toward change, we’ve been observing — saving the best ideas, testing them, and quietly merging them into a new kind of radio. The resulting modular, hybrid design is innovative and versatile, yet still a pleasure to use.
In particular, operators who’ve used our K3S transceiver and P3 panadapter will find the K4’s controls familiar, and its complement of I/O compatible with their existing station. But they’ll also discover a new level of convenience in the bright, 7” touch display, which combines a large panadapter with three intuitive multi-function controls. Everything you need is at your fingertips, including a unique built-in help system.
