via the RSGB: WRC-19 Day-3: kHz, MHz and GHz

Amateur radio interests at WRC-19 span an amazing range of frequencies and applications from kHz to GHz.

Day-3 saw the start of the Wireless Power Transmission topic. Agenda Item 9.1.6, specifically considers its high power use for charging electric vehicles, termed WPT-EV. Whilst it operates at relatively low frequencies such as 19-21 or 79-90 kHz, the kilowatts involved and nature of the switch-mode electronics create significant concerns regarding spurious emissions from its harmonics that may range up to HF.
