Hams concerned with the interference capability of broadband over powerline (BPL) technology are giving the greenlight to the recent announcement of BPL deployment in Texas by TXU, a local utility. "If TXU is going to install a BPL system, the ARRL is glad that TXU has chosen Current's system--which avoids using spectrum allocated to the Amateur Radio Service--in preference to one that has proven to be problematic," the group reports. The Current technology avoids putting high-frequency energy medium-voltage lines by using low-band VHF (30-50 MHz) instead.
