Sounds like a problem to me. For kits, you can test a properly built kit, and there's a procedure where you put language in the manual that says that when built as instructed, the kit is expected to conform. You can self-certify (declaration of conformity) but if there's a problem, you'd really rather have results from an independent test lab in hand. -- Dave's Engineering Page: http://www.dvanhorn.org I would have a link to http://www.findu.com/cgi-bin/find.cgi?KC6ETE-9 here in my signature line, but due to the inability of sysadmins at TELOCITY to differentiate a signature line from the text of an email, I am forbidden to have it. -- http://www.piclist.com#nomail Going offline?
