Today we learned about the latest addition to the Elecraft product line, the Elecraft K4<\/strong>.<\/p>\n

This fills a niche in the Elecraft product line and is certain to directly compete with the likes of the Icom IC-7610<\/a> and a number of Flex Radio<\/a> transceivers, among others.<\/p>\n

Elecraft describes the K4 as having a “modular hybrid architecture”. Below, I’ve pulled the text and images from the Elecraft product brochure.<\/p>\n

Wayne Burdick (N6KR) of Elecraft notes that tomorrow (Friday, May 17, 2019) the Elecraft site will (re)launch a K4 product page with pre-order\/reservation page.<\/p>\n

I plan to learn more about the K4 and report back during Hamvention this week. Stay tuned by bookmarking the tag Elecraft K4<\/strong><\/a>:<\/p>\n

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

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

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

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

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

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

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

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

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

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

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

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

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

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