If you or your significant-other use some of the specialty tea

throw out the little cans it comes in...they can be recycled

made of tin-plated, light sheet steel.

Did you save any of those thin metal boxes AOL was mailing their
CDROMS in a couple years ago? They look to be just thick enough for
some small SMD designs.

Not the thin ones. About 8 years ago, the Bank of America chain
was handing out "Christmas boxes" of AOL material (including CD)
which were at least an inch and a half deep. Unfortunately, the
box lid folded over the edges of the main box part and that did
not make a good enough metal-to-metal contact along the edges.

The tin-plated steel tea and coffee boxes have plastic-paper
lids (throwaway) and the lip at the top will support a metal
or PCB cover that can be sheet-metal-screw secured in place.
Better raw material for a box to shield RF in my thinking.
Solderability is great anywhere on the surfaces, good for
making connections to the can "ground."

Service to my country? Been there, Done that, and I've got my DD214 to
prove it.

Me too. ["R-A all the way" :-) ]

Well, I was U-S, (Drafted, for those who don't know) but I tested out
of a three year electronics school while in basic training and was
awarded the MOS for a TV Broadcast engineer. I went straight from basic
training to working in CATV, CCTV, AML type Jerrold Microwave video
links and even a little RADAR work.
