A little study on Faraday shielding.  I was baffled from previous experiment and wanted to get a better handle on  why I was getting such little isolation.   I replaced three of the cover plates with a little copper sheet I had around  and found I could control the isolation by holding down the copper sheet down.  Show below blue-taped together.  On top is a monopole driven by my 10 mW HacRF and by the side is a 1/2 W HT with cheesy rubber duckie antenna.  With the 1/2 W module I get full quieting and with 10 mW no quieting.  So 10 - 12 dB isolation?

More later.
