My recording attempts so far have yielded mixed results. Been visualizing the live spectrum with my phone and Spectroid. Seems to work some of the time but other times it won't.

When I get this https://pic8.co/sh/03mMMf.png , I think it's something to do with the electric grid because there's a clear peak at 50 Hz and the first harmonic. (Yurop uses 50 Hz)

But other days I get this https://pic8.co/sh/DyTi89.png

Today I recorded the spectrum of the appx. 70 Hz signal and I thought I had finally found the best settings in Spectroid. I thought I had won and at least found good settings to visualize. Then I tried again and... hardly any signal.

Things I have tried: Bought an USB to XLR Adapter for the one mike I own (Shure Beta 58A) This combo technically works but the noise floor is atrocious. For the level I'm looking at it might as well be "noise to signal".

I've set my mind to find better recording equipment. (And set up a web site and advertise it on a local billboard but I need good data for that)

Condenser instead of dynamic: https://www.thomann.de/de/behringer_ecm_8000.htm

Now I need a recommendation for a good digital recorder. Zoom and Tascam seem to have good products.

They all seem to be capable of 32 bit recording https://www.thomann.de/de/portable_recorder.html and 96 kHz sampling, which theoretically should not matter for this low low frequency application.

Money is not the main issue, buy once, cry once. Reason why I'm asking is disappointments with "great" products in the past. Looking for a good product with few ragrets. A live spectrum would be a feature I'd love during recording but that'd be a luxury.

Oh, almost forgot... Today, at a customer's house I worked on something IT related. Every time things got silent, "Siehe Da!" I heard the hum. I asked the (older) couple and she heard it, he wasn't sure. They live 3-4 kilometers away from me. Three weeks ago, my step son and his girlfriend were over to visit. When we had breakfast, she asked about that strange noise. Last fall I went to the forest, trying to locate the sound or at least find differences in its level. I drove, then walked about 4 kilometers from where we live and still heard it. What I'm saying is, I don't think I'm imagining this. If I do, I indent to find out.

There's a hum at my old man's house on moist days. High tension lines are just behind the backyard. Had a friend who's wall was humming, turned out to be a yellow jacket hive in the wall. Back when I was a high school jerk we had a substitute that was clearly new and nervous. I started humming, 4 or 5 other guys around the room joined in. She couldn't figure out who was doing it or how to stop it. She ended up getting a more experienced teacher to lay down the law.
