Out of curiosity, I went online and bought the nicest galvanized steel box that $12 would buy.  I'm not sure what gauge steel but it feels very sturdy.  Almost armchair copy - albeit sounds a little muffled with the lid closed .  I guess more cowbells isolation = nicer, thicker copper box - I see the dollars flying away if I were serious.  I have found a solution: an Altoids tin!  By removing the transmitter rubber ducky, installing a dummy load a placing it in a an Altoids can I can knock the signal down low enough so the "external RF in the Baofeng is solved" when it's in it's box.
