I made a few videos of the simple microwave / 2.4GHz meter dealing with work office's microwave oven--woe be unto whomever hangs around the hinge.
The first is a full examination of the space of the microwave oven, and is entirely inappropriate for those with short attention spans (stick to the second video, you).
This one is a short proof the detection is when the microwave oven is busily heating my hot water for tea.
The other amazing news is there is a very strong microwave signal that the northwest corner of the roof of Ryerson intercepts that appears to be coming from either the Admin building or the hospital: it strongly peaks in the southwest direction, almost pegs the meter on the 200mV scale, and when I added a headphone to the meter I could audibly hear some sort of signal that reminded me of a TV video sync noise.
What is this signal? Am I hearing a horizontal sync? Or is there some other signal that has a repetitive sync noise that runs at 12-18 kilohertz?
