Anyone else been getting static bursts on their EVP recordings right around 3am?

Yeah this has happened to me more than once. Did a spirit box session at a location in Suffolk last year, somewhere around 3am we started getting these really aggressive static bursts between the sweeps, way different to the normal background noise. Almost rhythmic. My mate thought it was interference from nearby kit but we were the only ones there and everything else was switched off.

There's a lot of talk about the 3am thing being a inversion of 3pm which is supposedly when Christ died, so some people think the veil is thinner or entities are more active at that hour. Whether you buy into that or not, the pattern is hard to ignore when you've recorded it enough times.

Would be good to know if others are capturing this consistently or if its more of a one-off thing. Anyone actually managed to isolate what's causing the static spikes technically, or does it always come with something else on the recording?

@Marko the 3am thing is worth separating from the static issue itself because they're two different problems that sometimes coincide. The static bursts on spirit boxes around that hour can actually be explained partly by atmospheric conditions - ionospheric behaviour shifts noticeably in the small hours, which affects the FM band sweeping frequencies these devices use. That doesn't mean nothing interesting is happening, just that your baseline noise floor is genuinely different at 3am compared to 11pm.

What I'd suggest is running a control session with the spirit box in the same location but with nobody present and no intent, just let it record for 20 minutes at 3am and compare that spectrogram against your active sessions. If the static bursts cluster the same way in both recordings then you're looking at environmental interference. If they don't, that's when it gets interesting.
