Bill and all,
Although the grocery store oven liner will work, I prefer not to work on
a fully conductive surface because I don't like the idea of accidentally
shorting two things together when I lay them down, but YMMV.
Good anti-static mats can be inexpensive. Check out the ones at
TigerDirect (www.tigerdirect.com). Their ULT33122 is a 23.5 inch square
mat for $19.99, or if you want something larger, the ULT33121 is 23.5 x
47.25 inches for $24.95. Their wrist strap is ULT31418 priced at
$6.99. Other computer related outlets should have comparable prices.
An ESD safe work area costing around $30 should be palatable for most
builders - that is roughly in the range for the cost for one replacement
firmware chip from Elecraft, better to be safe than sorry.
73,
Don W3FPR
