"BPL is a Pandora's Box of Unprecedented Proportions" By Rick Lindquist, N1RL (ARRL) - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - https://www.arrl.org/forms/development/donations/bpl/ Here's the situation... Utility companies with deep pockets are promoting a new scheme -- with great potential for causing harmful interference to Amateur Radio operators nationwide. The FCC is considering possible rule changes to aid these commercial interests who want to use existing electrical power lines that run along nearly every street and road, and into every neighborhood, to carry high-speed Internet service into homes and offices. Why is this important to you? Broadband over Power Line ("Access BPL") feeds broadband digital signals onto power lines using high-frequency RF from 2 to 80 MHz -- right on top of 80 meters, 40 meters, 20 meters and every other popular ham band all the way up to 6 meters. And it's not just the ham bands -- short-wave listeners are at risk too. Although this technology is already allowed, the industry wants the limits to be relaxed -- with greater interference potential to your ham radio operation. These BPL signals could transform HF from a quiet haven that hams enjoy to a noisy industry wasteland, changing ham radio forever. It's already hard enough to maintain a regular schedule with your friends, hear weak DX signals, or copy a maritime ham in distress. Imagine trying to do that through several S-units or more of broadband garbage. Imagine not even being able to throw your rig in the car and escape it through mobile operation -- power lines are everywhere! Will you have to operate from a remote site just to enjoy a quiet QSO? .. . . David Sumner, K1ZZ ARRL Chief Executive Officer |
