The screen is beautiful and functions can be controlled from either buttons or the touch-screen. There is band-stacking on the touch screen, a nit people have complained about on the K3.

Like previous Elecraft radios, this can be added later if you think you need it. Preliminary is that it will not be necessary unless you operate in the presence of strong stations (multi-multi).

The rig will be addressable locally or over the internet with no additional software. I saw it operated from an iPad and Android is coming. The iPad screen looked exactly like the front panel, including the panadapter.

I did not hear any talk about sun-setting the K3s when the K4 comes out. I am sure there are many people who will want to buy the basic K3s and upgrade over time (or not) rather than plunk down $4,000 for the K4.

> What does this do to the value of a K3 or K3s? I expect there will be some coming on the market. Anyone who buys, or retains, a K3 or K3s will still have one of the finest radios ever made. We are at the point where the difference among the top 5 or so on Sherwood's charts is a decibel or two, almost within the margin of error and certainly beyond the ability of the human ear to discern. So, don't panic. The demand for the K3 series will be strong for many years to come.
