Elecraft K4 and K4D transceivers
• DIRECT SAMPLING + OPTIONAL SUPERHET (HDR) MODULE
Direct sampling allows for advanced filtering, NR, NB, noise nulling, etc.;
Optional HDR module provides the ultimate in dynamic range
• 160-6 M, ALL MODES, 100 W / 10 W; WIDEBAND DUAL RECEIVE
Main/sub receivers can be on same or different bands; single or dual panadapters
• MODULAR ARCHITECTURE
Add HDR module, future 15 watt VHF/UHF module, etc., as needed
• OPTIMIZED USER INTERFACE
Encoders for VFO A, VFO B, RIT/XIT offset; many user-programmable controls
• HIGH-PERFORMANCE TUNING AID
High resolution mini-pan, per-receiver, for accurate tuning & search
• NO-COMPROMISES CW
Silent PIN-diode T/R; fast QSK; many features for CW ops
• EXTENDED I/O
HDMI, Ethernet, analog/digital audio; ATU with 3 ant. jacks; up to 5 RX ant. sources
• VERSATILE SOFTWARE ENGINE
Powerful, fast-booting CPU accommodates future in-box software applications
• PORTABILITY
Light weight, low current drain – compatible with field operation
A direct-sampling SDR you’ll love to use
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.
160-6 meter, all-mode coverage & dual RX
The K4 includes dual receive over 100 kHz to 54 MHz. Since it utilizes direct sampling, there’s 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). An internal VHF/UHF module is also planned.
High-resolution mini-pan for each receiver
Our advanced fine-tuning aid, with its resampled bandwidth as narrow as +/- 1 kHz, is displayed separately from the main panadapter. You can turn it on by tapping either receiver’s S-meter or by tapping on a signal of interest.
Simple operation and setup
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. Usage information on these and other features is just one tap away, thanks to our built-in help system.
Rich I/O complement
The rear panel includes all the RF, analog and digital I/O you’ll need to complete your station. All K-line accessories are supported, including amps, ATUs, and our K-Pod station controller. The HDMI video output supports an external display with its own user-specified format.
Full remote control from multiple devices
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 in all remote displays.
Modular hybrid architecture
The K4 adapts to your needs, with three models to choose from: basic K4 with wide-range dual receive; K4D, with diversity receive; and K4HD, with a dual superhet module for exceptional dynamic range. You can upgrade or add options as desired, or as new technology becomes available. This extensibility applies to software as well. The K4's powerful, fast-starting CPU provides unlimited expansion opportunities.
