Or, to the contrary, is it reasonable to assume that modern Tempest equipment can work around theses impediments almost all of the time, therefore making any attempts at this futile?

Make a grey-scale cable by merging the RGB lines (AND the RGB return lines). Do not use a standard grey scale cable, these are typically intensity on green, which you do not want. Connect the cable and start playing with your colour scheme. The effect you want to achieve is one where all colours have the same intensity. When that happens your whole screen should be the a uniform grey area. Revert to the regular cable and save your palette configuration. I imagine this would be effective against all of the middle range van-eck monitoring equipment. It will not be effective against equipment that looks for phase distortion and signatures in an attempt to discriminate against the three signals. Equipment capable of the latter would be extremely complicated and expensive to design and produce; I suspect there has been no call for it to date, given that if you are dealing with a target who understands the risks of van-eck they usually have shielding and or a faraday cage. -- "Of all tyrannies a tyranny sincerely exercised for the good of its victims may be the most oppressive. It may be better to live under robber barons than under omnipotent moral busybodies, The robber baron's cruelty may sometimes sleep, his cupidity may at some point be satiated; but those who torment us for own good will torment us without end, for they do so with the approval of their own conscience." - C.S.
