Have a PhD in physics/astronomy, so—full disclosure—I'm not an expert here... I skimmed the paper and I have no idea what he's talking about.
Given that half of his eight references are to his own papers, and the other half are textbooks or the Heaviside's original work, I think we can assume that he's doing some very niche work or a crank.
