VLF monitoring 29-10-20
1Частный мониторинг ЭМП до 24 кГц. Тестовые измерения.
Использована магнитная антенна и ПК с линейным аудио входом. Антенна представляет собой колбу 100 мл, заполненную порошком оксидов железа, с внешней стороны на колбе равномерно приклеены заводские катушки размером не более 1*1*1 см, в количестве 12 штук соединённых последовательно - 3,72 кОм, 540 мГн, одноимёнными полюсами направлены к центру колбы. 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. The antenna is a 100ml flask filled with iron oxide powder, factory coils with a size of no more than 1 * 1 * 1 cm are evenly glued to the outside on the flask, 12 pieces connected in series - 3.72 kΩ, 540mH, with the same poles directed to the center of the flask. 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:
