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. No-soldering kit; also available fully assembled and tested, the K3 is comparable in both features and performance to transceivers listing at up to six times its price.

In a first for the industry, the K3’s identical main receiver and subreceiver 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.

The K3 is the only deluxe transceiver that is targeted at both home and field use. Weighing just 8 pounds and having dimensions of 4” x 10” x 10” HWD (10 x 25 x 25 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 100-W 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.

Available options include: built-in 100-W automatic antenna tuner with two antenna jacks (KAT3), subreceiver (KRX3), general-coverage front end band-pass filter module (KBPF3), 100-W stage (KPA3), RF I/O unit for RX antenna, IF Out and transverter interfacing (KXV3A), digital voice recorder (KDVR3) and our all mode 2-m (144-148 MHz) all mode internal option (K144XV).
