The K2 is a full-featured HF transceiver with the options you have come to expect from radios costing over twice as much. Two VFOs with multiple memories, split TX/RX operation, RIT/XIT, full break-in CW, memory keyer, narrow IF crystal filtering, excellent RX dynamic range and IF derived AGC are standard on the K2.
Performance: We've designed big rig features and performance into the K2. Eric and Wayne are experienced CW operators, so solid CW performance (in addition to SSB) is a priority with the K2. Excellent sensitivity and dynamic range, Full QSK Break-in (diode switched), adjustable RX/TX CW pitch, High Speed Memory Keyer, Selectable RX Sideband, and Sharp IF Crystal Filtering are standard. Check out our K2 Performance Number Comparisons with other radios for more details.
Low Power Consumption
The K2 is designed for use both at home and in the field. The K2’s low receive current (approx. 150 mA in battery save mode) makes portable operation possible from small gel cell batteries. The K2 even includes an option for an internal 2.9-Ah rechargeable battery.
Easy Alignment: No sophisticated test equipment beyond a digital multi-meter is required to align the K2. Our built-in microprocessor and A/D circuitry monitor all important signals and provide user feedback during calibration. They even include a built in general purpose frequency counter, volt meter and radio current drain meter. Our thousands of K2 owners will attest to their success building the K2!
Customizable: We've designed the K2 for easy user modification. All interfaces and signals are fully described in the manual.
Note: This product is a kit which may involve building the product by selecting individual components, soldering them to the circuit board, winding toroids, installing LEDs and displays, calibrating circuits to meet specified performance levels.
After twenty years of offering our kit-builders the KPA100, we have retired the amplifier. Several of the parts needed to build the amp are no longer available. We will continue to provide support to our KPA100 customers. If you are looking for an amplifier option for your KPA100, please contact Elecraft Support.

Important Note: The KUSB cable cannot be directly plugged into the K2 without damaging components in the K2. A custom-built cable must be placed between any standard RS-232 connection and the K2 Aux I/O connector. This pertains to PCs with existing RS-232 ports, USB to RS-232 converters and our own KUSB cable. Review the K2 Connection Instructions in regards to using the KUSB with the K2.
