The Elecraft KX2 is a compact, 80-10 meter SSB/CW/Data QRP transceiver, measuring 5.8” x 2.8” x 1.5” and weighing 13 ounces, capable of up to 10 watts TX output. It features an optional internal 2.6 amp-hour Li-ion battery, providing up to 8 hours of typical operation with a 135 mA receive current drain, and includes a built-in mic, 0.5-W speaker, and wide-range internal ATU (KXAT2) for random wire, dipole, or whip antennas. The KX2 also incorporates a 32-bit DSP with dual watch, stereo audio, user-programmable filter bandwidths, noise blanking, noise reduction, and auto-notch, supporting built-in RTTY and PSK data modes without a PC.

In comparison, the Elecraft KX3 is a larger, 160-6 meter all-mode transceiver with up to 15 watts TX output, and an optional 2 or 4 meter VHF module. The KX3 offers a more extensive control set, a 1-W speaker, and a 1.0 kHz CW / 3.0 kHz SSB roofing filter option (KXFL3), drawing an average of 180 mA on receive. Both transceivers integrate with the KXPA100 100-W amplifier and support KXPD2/KXPD3 keyer paddles and the MH3 microphone, with the KX3 also compatible with the PX3 high-performance panadapter for real-time band visualization.
