[Elecraft] Steel in some K-line enclosures

[Mike K2MK]

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
