Your MW is not leaking, if it would be the DVM would go 'bananas'. The small leakage is normal. There is no such thing as 'perfect shielding' and with 700W inside it takes better than 1:1000 shielding to keep total radiation under 0.7W. That is very good shielding. The real leakage is probably 50mW or so. The DVM is sensitive and picks this up. Peter -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
