Hi Jim, As a point of curiosity here's a posting from Wayne (04/15/2010) describing the reason for using steel in the P3 enclosure:
/The P3 enclosure is being fabricated entirely from corrosion-resistant steel (plated before painting) rather than aluminum. Production and field test units will weigh about twice as much as the prototype you tried out (about 5 pounds). Besides making the unit heavy enough to not slide when you push the buttons, the steel enclosure will reduce EMI generally -- in or out. The use of steel also makes the enclosure very strong, so that you could, if you wanted, put a heavy 20 A linear power supply inside to power the K3, etc. While we don't have any current plan to offer an optional internal power supply for the P3, some of us (including me) will be rolling our own. In my case it will free up some valuable desk space. (Anyone need a Samlex power supply? Pick-up only!) 73, Wayne N6KR / Jim AB3CV wrote > Just was playing around with a magnet and noticed that the KAT500, KPA500 > and P3 all have some of their panels made of steel rather than aluminum. > > I've been wondering how to keep some of my little homebrew boxes from > sliding around yet blended with the K-Line feng shui.
