This is a special offer built by Elecraft. The KX2 with the ATU built in.
Elecraft's KX2 stealth transceiver can go wherever your imagination takes you. Thanks to state-of-the-art construction techniques, it's the smallest full-featured HF radio on the planet. Yet it puts out up to 10 watts, covers 9 bands, and shares many features with the KX3. It also works with the KXPA100 amplifier.
To maximize your freedom to roam, you can outfit your KX2 with an internal 2.6 amp-hour Li-ion battery. Current drain is as little as 135 mA, yielding up to 8 hours of typical operation on a single battery charge. Includes the internal automatic antenna tuner module (KXAT2), which can tune a random wire, dipole, or whip on multiple bands.
A rear tilt-foot angles the KX2 for use on any surface, from desktop to park bench to rock. The KX2 also makes a great moble rig, and can even be used hand-held. It includes a built-in mic for HT-style operation.
The KX2s powerful 32-bit DSP offers features dual watch, stereo audio, user-programmable filter bandwidths, noise blanking, noise reduction, and auto-notch. RTTY and PSK data modes are built in—no PC needed—as well as a memory keyer and digital voice recorder for transmit.

The Elecraft KX2 is the most powerful compact HF transceiver currently available for ham radio HF operation. Developed from the famous KX3, it is a slimmed down version, but still retains key features that maintain unprecedented performance. And this really is why so many customers use Elecraft for portable operation.
The KX2 can easily fit into a medium sized coat pocket, yet can deliver up to 12W output. Using the optional internal battery, it easily delivers 5W output for lengthy periods, certainly satisfying most operators needs for a typical day out. An additional battery can quickly be replaced or even plugged into the external DC sock for even quicker supply change over.
The bits missing compared to the KX3 may not be of much consequence to a lot of portable operators. You don't get 160m or 6m operation. You also don't have the option of using the external PX3 panoramic display. VHF operation on the 4m and 2m bands is also not an option. There is also no optional roofing filter to improve the bandwidth performance for CW.
The KXAT2 internal automatic antenna tuner converts a wide range of impedances presented by antennas to a value close to 50 ohms, non reactive (i.e. low SWR) for the KXAT2 itself. This allows the transmitter in the KX2 to deliver full RF power in transmit and can also improve sensitivity in receive. Even many non-resonant random wire antennas can be used effectively with the KXAT2 installed. When commanded to tune, the KXAT2 searches for the best match (lowest SWR to the transmitter). Once a tuning solution has been located, the solution is stored so that retuning requires less than 1 second. One tuning solution is stored for each band.
