BPL

BPL - Broadband over Power Lines
This is also known as Power Line Communications (PLC), and poses a serious threat to effective communication by radio amateurs. The technology allows an electricity distribution network to deliver ADSL communications. A byproduct of this technology is broadband RF interference which have been measured at above 10dB over 9. Most affected are the HF and VHF bands, but other bands will be affected depending on location. In Australia VK5VKA Stephen has put together a non-technical webpage describing BPL and its potential effects on amateur operators. VK1OD Owen also has an excellent BPL information page on his site.
