Kettle caps working as a receiver on stove. All voice you hear on video is received by those two caps :). We had 200W to 80m band from FT-990 and Ameritron AL-80A amplifier and antenna OCF-dipole on roof. This also works with barefoot 100W!
I seen something like that on TV before. Also with a lid on a stove top, close to a short wave radio station.
They said the black iron oxide of the stove reacts like a semiconductor and rectifies the high power HF. Then the LF current creates the vibrations through magnetic force. In WW2 they used Iron oxide (Blued Razorblades) for Foxhole radios.
Come on, guys.... I ain't buyin it.
