Introduction
This comprehensive manual covers all the features
and capabilities of the Elecraft K3 transceiver. We
recommend that you begin with the Quick-Start
Guide (pg. 4). The Front Panel (pg. 11) and Rear
Panel (pg. 17) sections are for general reference.
Basic Operation (pg. 21) and Advanced
Operation (pg. 33) fill in the details.
Anytime you add new filters or options, refer to
Configuration (pg. 46).
K3 Features
The K3 offers a number of advanced features to
enhance performance and versatility:
Receiver
• Up to five crystal roofing filters with
bandwidths as narrow as 200 Hz (pg. 23)
• High-performance, fully independent sub
receiver, also with up to five crystal filters,
allows true diversity receive with two
antennas (pg. 37)
• Variable-bandwidth crystal filters that track
DSP filter settings
• Narrow ham-band front-end filters, plus
wider band-pass filters for general-coverage
receive (pg. 45)
DSP
• 32-bit I.F. DSP for advanced signal
processing, including full stereo and other
binaural effects (pg. 35)
• Passband tuning and programmable
DSP/crystal filter presets (pg. 14)

• Internal CW-to-RTTY or CW-to-PSK31
encoding for casual digital-mode QSOs
without a computer (pg. 34)
