Most of the line about radio waves is from Dear Esther:

I will become a torch for you, an aerial. I will fall from the sky like ancient radio waves of flawed concrete. Through underground springs and freezing subterranean rivers. Through the bacteria of my gut and heart. Through the bottomless boat and forgotten trawlers where nobody has died. Like the hermit and Lot’s wife, I will fossilise and open a hole in the rock to admit me through.

It's sorta one of my all-time favourite free verse snippets, partly because of the bizarre vocabulary and qualifications, so it's not very surprising it ended up in Vokram untampered.
