VLF monitoring 03-11-20
Частный мониторинг ЭМП до 24 кГц. Тестовые измерения.
Использована магнитная антенна и ПК с линейным аудио входом. Антенна - диаметр 310 мм, диаметр медной проволоки 0,1 мм - сопротивление индуктора 2,9 кОм, индуктивность индуктора 2,5 Гн, ось восток-запад.
ОС Ubuntu 20.04 и спектроанализатор Spectrum Lab.
На спектре можно видеть суммарную картину ЭМП - от электросети и бытовых приборов до специализированных передающих станций. Некоторые станции описаны здесь:

Private EMF monitoring up to 24 kHz. Test measurements.
Used a magnetic antenna and a PC with audio line-in. Antenna - diameter 310 mm, copper wire diameter 0.1 mm - inductor resistance 2.9 kΩ, inductance 2.5 H, east-west axis.
OS Ubuntu 20.04 and Spectrum Lab spectrum analyzer.
On the spectrum, you can see the overall picture of the EMF - from the power grid and household appliances to specialized transmitting stations. Some stations are described here:
