Description

K3S/100W-F


Elecraft have raised the bar once again by upgrading the K3, now to be known as the K3S. The basic design has been retained, but there have been some major changes to this new edition.

The K3SYN was introduced to all serial numbers from 8000 onwards. The remaining features are introduced to the new model K3S, which will start from serial number 10000.

  • New soft touch VFO knob.
  • USB port 0 integrates remote control and line level audio, thus eliminating the need for PC sound card and the associated cables.
  • KXV3A board now replaced with KXV3B board which will now be included as standard.
  • The 12m - 6m pre-amp will now be fitted as standard.
  • Multiple attenuators of 5, 10 and 15dB now included.
  • K3ATU option now has true relay bypass and lower insertion loss.
  • Re-designed receiver audio output speaker section New high accurate high speed CW including SPLIT operation.
  • Coverage of the 630m band (470kHz) and lower.
  • Redesigned low power 10W (driver section) and upgraded 100W PA section.
  • The optional P3 Panoramic Adaptor will now have retro fit hardware and firmware for transmit monitoring.

 Elecraft's state-of-the-art K3 transceiver offers a unique combination of ultra-high performance and affordability. Both 100 watt and 10 watt (upgradeable) models are available, the K3 is comparable in both features and performance to transceivers that are more expensive.


In a first for the industry, the K3's identical main receiver and sub-receiver each feature a high-dynamic-range, down-conversion analog architecture. This allows Elecraft to provide roofing filters with bandwidths as narrow as 200 Hz, while up-conversion designs have roofing filters typically 3,000 to 15,000 Hz in width.

Unlike some competing down-conversion designs, the K3 also provides 6-meter coverage, as well as continuous tuning from 0.5 to 30 MHz. Each receiver has its own bus-switching mixer, narrow ham-band front-end filters, 32-bit I.F. DSP, low-noise synthesizer, and up to five crystal roofing filters.


Both fixed- and variable-bandwidth crystal filters are available. The variable filters are available in both data/CW and voice-mode bandwidths, and allow close tracking between crystal and DSP filtering - a feature not available on any other rig at any price.


The K3 is the only deluxe transceiver that is targeted at both home and field use.Weighing just 3.6kg and having dimensions of 10H x 25W x 25D cm, it's well-suited to demanding DXpedition or Field Day operations.

Its receive-mode current drain of less than 1 amp greatly facilitates battery or solar-powered mobile/RV/marine installations. But unlike smaller portable transceivers, the K3's user interface is optimized for ease of use, and its feature set rivals units many times its size and weight.

The transceiver is offered both factory-assembled and as a modular, no-soldering kit. Either way, K3 owners can start with a basic version of the transceiver, at lower cost, then easily add modules later, such as the internal subreceiver, ATU, and 100W stage.

To ensure identical performance of both pre-built units and modular kits, modules are 100% assembled and tested at the factory. Builders learn the radio theory behind each of the modules during assembly, and acquire skills that will enable them to easily add future modules or upgrades.


Two 32-bit digital signal processors provide true software-defined features, along with expansion memory to handle future signal processing tasks and operating modes. The operator will have full control over any operating situation, with 8-band receive and transmit EQ, stereo speaker/soundcard outputs, binaural effects, and advanced noise reduction.


Also included is built-in PSK31, CW, and TTY decode/encode, so the operator can enjoy the excitement of data communications with or without a computer. The rig's rich I/O complement includes an isolated sound card interface, front/rear mic/phone jacks, dedicated serial I/O, and band data. An optional module provides transverter in/out and RX antenna in/out jacks. The latter allow the use of RX-only, in-line filters for extreme operating environments.
