The phases of the moons of Neptune can affect radiated emissions tests, or so it seems, sometimes! On an open-air site, there certainly can be effects, especially if surfaces are damp. It's not only condensation, and not only the EUT, that matters. Indoors, I suspect you can find effects if you go looking for them, but usually RH doesn't change very much in the short term. If you measured an EUT at 25% RH and then at 95% RH, the results should only be compared if they were obtained at the same temperature. -- OOO - Own Opinions Only.
