Don't need the 590, but I am going to be selling mine when I can get to the barn to get the boxes. It is fairly simple. Will come with a P3 and the add-ons for 2 antennas and for using VGA. Kpod (VFO) and Genovation also. On a day when I feel good and get a weather break I'll get the boxes and set a price. Bill W2BLC
