Anyone else been getting interference on their recordings near old cemeteries lately?

Had something odd happen a few weeks back at a churchyard just outside Norwich. Was running my recorder for about 40 minutes and the whole middle section just... came out as this low hum with crackle over the top. No obvious explanation for it, no pylons nearby, nothing like that.

What gets me is the edges of the recording were perfectly fine. Just that chunk in the middle. A friend who does this more seriously than me reckoned it might be localised energy disruption but I honestly dont know enough to say either way.

Has anyone else noticed it tends to happen more in older parts of the cemetery rather than the newer sections? Thats been my experience anyway, small sample size as it is. Would be really curious to compare notes with people who are more experienced with EVP work than me because I feel like I keep missing something obvious.

@robin_fletcher which recorder were you using? That matters quite a bit. Some of the cheaper digital units are terrible near anything with old iron railings - the metal can interfere with the circuitry more than people realise.

Been doing EVP work in Suffolk churchyards for years and I've had similar dropout but usually traced it back to equipment rather than anything paranormal. Doesn't mean it ISN'T worth investigating further though. The Norwich area has some genuinely interesting sites.

What time of day was this? And was there any mobile signal in the area, because 4G masts near old sites are a nightmare for recordings.
