Elecraft’s state-of-the-art K3S transceiver offers a unique combination of ultra-high performance and affordability.
The factory-assembled K3S is comparable in both features and performance to transceivers listing at up to six times its price.
In a first for the industry, the K3S’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 for both receivers. Up-conversion designs have roofing filters typically 3,000 to 15,000 Hz in width. 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 KBPF3A option extends receive coverage down to 100 kHz, covers all SWL bands, and allows 0.5 mW transmit output on the 472 kHz (630 m) band for use with external amplifiers.
The K3S is the only deluxe transceiver that is targeted at both home and field use.
It’s well-suited to demanding DXpedition or Field Day operations. Its receive-mode current drain of typically 1 amp greatly facilitates battery or solar-powered mobile/RV/marine installations. But unlike smaller portable transceivers, the K3S’s user interface is optimized for ease of use, and its feature set rivals units many times its size and weight.
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. Users of new digital modes such as FT8 will gain a new competitive edge since the K3 has the industry's lowest noise floor and highest dynamic range. This combination of benefits is simply not achievable with the direct-sampling technology found in most "pure" SDRs.
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. The K3S also provides transverter in/out and RX antenna in/out jacks. The latter allows the use of RX-only, in-line filters for extreme operating environments.
