a level of −6.6dBm (220 microwatts), making the total full channel power 24dBm, (250 milliwatts). Typical short wave radio receiver sensitivities are at −100dBm (tenths of a picowatt) level. In the UK there have been suggestions that users of powerline equipment should be prosecuted under the Wireless Telegraphy Act, if they cause interference to official radio systems. Also GCHQ has published concerns that such interference affects its ability to monitor radio activity in the UK.
