Dick, I have only the KX3 - no KX2 - but I can tell you that with the basic unit, no add-on heat sink, operating PSK31 heated up the unit enough for it to fold back just about every time I used it. I put on the heat sink offered by Pro Audio Engineering, did it the optimal way, and it made a world of difference. No fold back, the heat sink only warm to the touch.
I also use the rig for WSPR-2, almost 24-7, but only running 2 watts. After the 2 minute transmit cycle completes the heat sink is only slightly warm. Can't say how the Elecraft replacement heat sink compares to the one I bought, but I think you will want something other than the stock unit.
