OVERVIEW<\/h3>\n

A direct-sampling SDR you\u2019ll love to use<\/b><\/p>\n

Our new K4 harnesses the latest in signal processing while retaining the best aspects of the K3S and P3. The resulting user interface makes the technology transparent, allowing you to focus on working the world.<\/p>\n

160-6 meter, all-mode coverage & dual RX<\/b><\/p>\n

The K4 includes dual receive over 100 kHz to 54 MHz. Since it utilizes direct sampling, there\u2019s no need for crystal filters in the K4 or K4D (see Models, back page). For extreme-signal environments, we offer a dual superhet module (standard in the K4HD).\u00a0\u00a0<\/span>An internal VHF\/UHF module is also planned.<\/p>\n

High-resolution mini-pan for each receiver<\/b><\/p>\n

Our advanced fine-tuning aid, with its resampled bandwidth as narrow as +\/- 1 kHz, is displayed separately from the main panadapter.\u00a0\u00a0<\/span>You can turn it on by tapping either receiver\u2019s S-meter or by tapping on a signal of interest.<\/p>\n

Simple operation and setup<\/b><\/p>\n

The K4 features a large, full-color touch display, combined with a rich set of real controls. Per-VFO transmit metering makes split mode completely foolproof. Band-stacking switches and per-receiver controls are both intuitive and versatile, adapting to operating context.\u00a0\u00a0<\/span>Usage information on these and other features is just one tap away, thanks to our built-in help system.\u00a0<\/span><\/p>\n

Rich I\/O complement<\/b><\/p>\n

The rear panel includes all the RF, analog and digital I\/O you\u2019ll need to complete your station.\u00a0\u00a0<\/span>All K-line accessories are supported, including amps,\u00a0\u00a0<\/span>ATUs, and our K-Pod station controller. The HDMI video output supports an external display with its own user-specified format.<\/p>\n

Full remote control from multiple devices<\/b><\/p>\n

The K4 can be 100% remote controlled, via Ethernet, from a second K4 as well as a PC, notebook, or tablet. Panadapter data is included on all remote displays.\u00a0<\/span><\/p>\n

Modular hybrid architecture<\/b><\/p>\n

The K4 adapts to your needs, with three models to choose from:<\/p>\n
