[spam][crazy] How a Hobbyist Might Start Building Shielded Rooms
step 1: be able to measure shielding effectiveness This takes two radios: an emitter and receiver . It also takes a variety of antenna to handle various frequencies and modes. There are a number of formal guides (commercial and military specs) for how to do this, which are a good starting point but leave some things out. Basically, you measure signals under identical conditions both with and without the shielding. This gives a metric of attenuation for the exact signals and locations measured.
If you are either smart or paranoid or both, and hence are running to a shielded environment without desire to ever leave, you can still perform experiments inside your environment, and measure the ability of external signals to propagate inward.
But basically most shielded environments slowly fail due to metal oxidation, wear & tear, resonance ... so as said before an environment is only shielded if that shielding is measured. Regardless other people need shielded environments too, which means public data and plans.
might make sense to start with hand measurement, since automation is kind of inhibited maybe do the hand measurement with an automatable tool like an sdr with live power spectrum or whatever
maybe do the live power with gnuradio, so additions could possibly merge with them other options include pothos or whatever 3rd party tools are big at the time
