Hi Kristinn, The KX3 uses a different transceive architecture from the K3 -- one that is more consistent with a portable, lightweight radio that has lower current drain and a lot fewer components. But it's not a toy. It will have performance comparable to many full-size transceivers. We'll have a lot more to say about this when we complete the update from prototype to field test. As far as features go, the KX3 is exactly midway between the KX1 and K3. Like the KX1 it is fully self-contained, with optional internal batteries, ATU, and attached keyer paddle. But it covers 160-6 m, like a K3, as well as all modes. It has a user interface that's very similar to the K3's, including the same full-sized LCD, five encoders (optical for VFO A), and full-custom knobs and switches. It has many of the same special features as the K3, including built-in decode/ display of CW, RTTY, and PSK31; dual VFOs; full stereo audio effects, etc. It has extremely low current drain for a state-of-the-art DSP-based transceiver, at about 150 mA minimum (LCD backlight off). You should get from 5 to 15 hours of operation from internal batteries depending on your transmit/receive ratio.
