The reporter personally saw S9+ noise levels on the mobile transceiver. He personally saw that receiver hearing signals from all over the world as we drove to the test area. He saw that recevier rece
I have personally visited 6 of the BPL test areas. Though the specifics varied from site to site, all emit strong RF noise continuously across many MHz of spectrum, continuously vs time and across a
The Wall Street Journal article relied heavily on reports about the BPL system in Penn Yan, NY. Here are follow-up articles about Penn Yan: http://www.arrl.org/news/features/2004/04/01/3/?nc=1 http:/
So, imagine that 100 hams converged on a BPL area to "demonstrate" that the BPL system is susceptible to interference. Does anyone think that the industry would suddenly see the error of their ways a
If you share this with them, they will have an unbiased business-case report to think about: <http://intel.si.umich.edu/tprc/papers/2003/246/Tongia-PLC.pdf> Ed I live in an area served by a co-op ele
The FCC started out with the premise that they were going to remove unnecessary restrictions on BPL. The NPRM removed no restrictions, but added two measures: a mandate that BPL equipment must be de
The information at http://www.arrl.org/tis/info/HTML/plc/bpl-deployment.html was intended to be used to communicate the essence of the BPL issues with Congressfolks, utilities, local regulators, etc.
I am surprised that Kerry has not picked up on the fact that his opponent supports something that has been a spectrum polluter in most of its deployments. Ed I don't imagine John Kerry has spent a lo
When all this started, we had the anwers about interference, and I truly believed that when they were put on the plate, the right choice would be made. To some extent, that was correct, but the proce

The value of amateur radio is without question. Take a look at http://www.gobpl.com/emcomms.html to see just how amateur radio contributes. Ed Hare, W1RFI ____________________________________________
For a rough estimate, *conservatively* assume 200,000 active amateurs. Conservatively, do they have, on average, $5,000 invested in the cost of their equipment, antennas, towers, feed lines, books, t
Send a letter that says that it includes a $500 check, then forget to include the check. That is how most parents get a phone call from the kids they are sending to college. :-) _____________________
I don't yet know if the Walmart systems are 900 MHz, 433.92 MHz or ???. There are a number of RFID systems, and most are on 900 MHz. Ed _______________________________________________ RFI mailing lis
It is very much in ARRL's best interest not to waste resources on non problems. To wit, our cooperative approach with the Home Phone Networking Alliance, the VDSL committees and even HomePlug all fo
HomePlug V.1 uses 4-20 MHz, with most amateur bands notched about 30 dB below the permitted FCC Part 15 levels. That is not enough to protect against interference in all cases, but is well worth the
Hard to say. Tom Rauch lives in a real quiet location, so I would estimate about 300-500 feet in his case. Others who have S3 noise already would barely notice one next door in the protected spectrum
HomePlug, HPNA and the VDSL folks all recognized that they had a potential interference problem. They put that problem on the table and addressed it head on. The BPL industry started off by saying th

ARRL gets only part of the credit here. The dedicated and correct work of the local hams in Cedar Rapids was the most important component to this success. ARRL supported that work, and provided a ju
