THIS STUDY.  WHILE HRES 230 DOES NOT SPECIFICALLY ADDRESS THE BPL CONCERNS
OF THE AMATEUR RADIO COMMUNITY, ROSS SAID THOSE CONCERNS WERE WHAT LED HIM
TO LOOK MORE CLOSELY AT BPLS IMPLICATIONS FOR THE PUBLIC SAFETY COMMUNITY.
HE NOTED THAT THE FEDERAL INTERAGENCY EMERGENCY SHARES SHARED RESOURCES
NETWORK USES HF, AND MANY STATES AND LOCALITIES STILL USE THE 30 50 MHZ LOW
VHF BAND FOR PUBLIC SAFETY COMMUNICATIONS SPECTRUM THAT SOME BPL PILOT
PROJECTS ALSO HAVE OCCUPIED.  ROSS SAID BPL INTERFERENCE ON HF WOULD BE
PROPORTIONAL TO THE EXTENT OF THE TECHNOLOGYS DEPLOYMENT USING MEDIUM
VOLTAGE POWER LINES.  BROADBAND ENERGY CANNOT BE PUT ON THESE LINES WITHOUT
CAUSING INTERFERENCE TO RADIO RECEIVERS USING THE SAME FREQUENCIES, HE
EXPLAINED.  HE ALSO SAID THE EXISTING EMISSION LIMITS ARE MUCH TOO HIGH AND
NEVER WERE INTENDED TO APPLY TO SYSTEMS LIKE BPL.  EXISTING BPL SYSTEMS
