Hi Don; I wouldn't build without a Mat.
See the Jameco site www.jameco.com part# 10575ck = 11.3x22" mat for $9.95. Get a wrist strap too; there were some for under $7.

My suggestion to use some conductive surface (alum.) assumes it is used only for construction (no power applied). During testing, you'd have to change the setup to prevent the rig from shorting! I'm glad you mentioned it! As I think about it, I can see that the metal top is a poor substitute for a real static mat and can do only 1/2 of what a true high-impedance / conductive mat can do. I honestly don't know the price of a static mat. I got mine free from work as it was soon to be tossed out. I've seen 'em in Mouser and I think they were $50 or so but I bet they can be had for less. 73! - Keith- -----Original Message----- From: Don Wilhelm [mailto:[EMAIL PROTECTED] I agree with all your ESD comments, but I would hesitate to suggest that anyone do electronics work on a completely conductive surface such as a sheet of aluminum. The possibility of a short to the work surface while testing or working on powered equipment is high. Even with low voltages, the current can be high and therefore dangerous. The surface should be conductive, but not of a low resistance. _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
