Aluminum boxes are also easily machinable and you won't have to mess around with sprays, etc. I'd stay away from anything "unusual" like plastic with sprayed-on shielding. Don't forget to use shielded cable grounded at one end, lots of bypass caps, etc. for inputs and outputs to the box. --=20 Carey Fisher Chief Technical Officer New Communications Solutions, LLC 678-999-3956 careyfisher@ncsradio.com --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
