Hi Jahman- Excellent news to read.- that you have effective back up! Your site is a very old established Hum site and if you have got measurements and independent witnesses- that is remarkable. 12.5 Hz is in the Earths' Schumann resonance band and would not be hearable. What you did hear , however, would it have been continuous? If not steady tone , any ON/Off activity showing on the equipment should tally with your hearing to show a common source. Something that is a must in this search for Hum cause. There is often a 'beat' or throb of a few cycles too, so even if you get it all the time at present, that beat could show up as a lower sideband- if the measuring gear is senstive enough. Recording the hum is extremely tricky and hasn't been done properly yet. Many have tried and some have published -but the jury is still out, to my best knowledge. Files can be posted here btw. PS: Insure your ears- you could get rich ! ;)
