Please...don't call any upgraded K3 as a K4. I would hate to have people think that my K3 is out of date per say. A K3 should always be a K3, but if you "add" any upgraded boards etc. then it is a K3 upgrade. NO K4.....! 73----------------------- Kyle N4NSS <<click this Enjoy the Magic of HF Radio.
