K3 Elecraft – 160 – 2 m* - 100-W High Performance All-Mode Transceiver


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. starting at just $1949 for the K3/100 (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.
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 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.
