Ok for the 60kHz (repeated) it is maybe only 32kHz because of the 16us sampling rate...
for the skin, it is just increasing the resistance of the cable, and cable have to be designed for that job, plugs too... and if allowing power to pass, it make losses unmissable... moreover there is nonlinear loads, the instruments, that will sure cause subharmonics to appear, in an uncontrollable way... basically making suche a fraud , HF or DC, may lead to uncontrollable result by theway another problem with HF or DC is that the peakvoltage will be more tha doubled and will destroy any switch supply used on the plugged instruments. if not destroying it may troublle only, cause shutdown... and even if it does not happen, it may happen note that if rossi allowed (he was not there so he could not refuse) that instruments be plugged on the same socket, it mean that he don't fear that phenomenon... Now I just thing that you should work on 9/11 and Apollo conspiracy theories, which are I hope more easy to support... 2013/5/26 Andrew <[email protected]> > ** > Please show me the page number on which the figure of 60 KHz appears.
