They won't want to put up with the interference. Bad idea. -SSB How can you be on CB and say that no one puts up with interference? Also, the actual number of hams affected is probably very small, so the point is interesting but probably better posed in the context of :"if we don't get novices again, with no code privileges, then..." 73, Chip N1IR. CB is intended for short range communications, under 120 miles. Rarely will a legal station be able to transmit much more than 20 miles, when the hash and trash aren't throwing their deadkeys and noise toys. Completely different subject. Chip, you probably haven't been out driving around in the areas they were testing BPL, while trying to work a net. You can hear, literally, the "motorboating" from BPL interference 40-50 miles away from a test area. By the time you're within 10 miles of a test area, the noise from the BPL (different from magnesium lights and other urban noise sources) is close to 20db over S9.. making working the net nigh-on impossible. We're talking, minimum, a 100 mile radius around a BPL test site where the interference from BPL makes Amateur HF communications, at a minimum, extremely difficult, and at worst, impossible. Now, mind you, this is receiving from a "compromise" antenna. I've tried switching types from my 40-foot, ICOM AH-4, tuned looped longwire, to Hustler "dummy loads", to Hamstick whips, to Iron Horse whips, to 102" SS whips tuned with LDG tuners, on the 10, 20, 40, 75, and 80 meter bands. ALL of them were affected to varying degrees, but none were affected so little as to make communications in these areas possible. So your contextual assumptions do not apply to this situation in the least. IMHO, BPL is a bad for the Amateur community, and for emergency communications in general. The interference on CB is a completely different story. -SSB |
