KX2 arrived yesterday after a ~15 week wait, which was pretty much spot on with Elecraft's original estimate.
One of the best features is, especially for a compact rig with limited dedicated controls, the ability to assign a programmable function button to an otherwise buried menu feature. For menu features that are binary choices (such as enable/disable CW transmit), not only does the PFn button activate the menu item, but it also toggles the parameter and dumps you right back into operating mode. For example, you can toggle between "CW transmit" and "CW practice (no transmit)" by pressing only two buttons. No need to go through deep menus. Kudos to KX2 designers for thinking ahead. One of the not so great features is the internal speaker. It's even raspier and more distorted than the forward-facing one supplied with the KX3. This is to be expected; there are design trade-offs and this rig wasn't designed to be a desktop model with high wattage audio output. My typical use case for the KX2 is to listen to it in the background on the desktop with good quality speaker audio, and then to switch to headphones/earphones when in QSO. So I'd like to build an audio amplifier to convert the KX2 headphone output levels to say 5 watt speaker output (one of the two channels will suffice) for listening to relatively undistorted audio in the shack. A good starting point is knowing what the output level and impedance is for the headphones jack. I measured approx 20 mV P-P (impedance unknown) at an audio output level around "AF 10" according to the KX2 display. Does this sound about right? Bonus points: First QSO with the KX2 was from Maine to Bermuda at 1 watt.
