You know, I think fortune tellers use crystal balls or such. I was taking a spectrum with my crystal and PMT.
Just testing some pre-amplifier circuits. You can see the spectrum build slowly, auto scaling keeps it nicely full screen.
Slowly building, background, suddenly it started increasing rapidly, I heard a jet, I am sort of in the approach path of a military air-base.. It was not an F16, I think, could have been an Euro fighter, maybe F15, maybe something larger... The spectrum increased rapidly, and acquisition returned to normal as the plane sound went away. I estimate the height at about 1000 feet when it passed over here. I was so fascinated looking that that spectrum change that I forgot to go look at that plane, no time, took just a few seconds..
So I thought about this for a week, and concluded that that airplane was carrying very radioactive material, so probably a nuclear weapon.
But I dunno if such a simple crystal and PMT setup can detect a nuclear bomb
1000 feet away? Any comments? If this was an Euro fighter, then Germany has the bomb. Now how is that Dr Watson? I think Euro fighter because I have this PC game, that sort of sound. F16 is common here, they fly over all the time, I know that sound. But maybe F15, and a US bomb, that is possible too. Or interference in my premap from the radar of that plane? I did not save the spectrum, I should have. Setup was not calibrated for energy at that moment either.
