New Mexico ARES members end river watch


(May 31, 2005) -- With water levels in the rivers of northern New Mexico finally falling, Amateur Radio Emergency Service (ARES) monitoring activities have ended. Members of several ARES teams sacrificed Memorial Day weekend plans to monitor the swollen rivers. New Mexico Section Emergency Coordinator Bill Kauffman, W5YEJ, was in the area May 27 to synchronize ARES activities with those of state and local emergency officials. An emergency operations center in Espanola provided a base of operations for radio amateurs and other emergency responders. Of special concern was the Embudo River. As of the morning of May 29, Gary Bonebrake, W5BI, reported that the water level was down another inch compared to the previous day's measurement. ARES operations stood down May 29, and ARES members were able to enjoy the last day of the long holiday weekend with family and friends. New Mexico ARES groups from Los Alamos, Santa Fe, Bernalillo, Sandoval and Rio Arriba counties provided emergency communication support and spotters at the request of the Rio Arriba County Emergency Manager.--Sandoval County ARES

[Power Lines and RF Fields]

Hams Encouraged by NEW Motorola BPL Technology


"The ARRL is pleased to hear Motorola's announcement of its Powerline LV system. This is the first Access Broadband over Power Line (BPL) system that has been designed from the start with radio interference concerns in mind."Motorola's Powerline LV system avoids using the medium-voltage (MV) power lines and introduces broadband signals only on the low-voltage (LV) side of the power transformer. This greatly reduces the potential for interference to and from radio users, especially radio amateurs. ARRL Chief Executive Officer David Sumner commented, "We know that medium-voltage (MV) power lines are no place for broadband energy, since there is overwhelming technical evidence that radio interference from BPL is unavoidable if MV lines are used. By confining their Access BPL system to LV lines and by adding hardware notch filters for additional protection to amateur radio frequency allocations, Motorola has addressed our interference concerns."
