End in Sight for 'Third Battle of Bull Run'?
ARRL Chief Executive Officer David Sumner, K1ZZ, once termed the battle
of Broadband over Power Lines (BPL) in Manassas, Virginia as the "Third
Battle of Bull Run." While the war against harmful interference to
Amateur Radio via BPL is not yet over, the battle in Manassas might
soon be coming to an end.
In a Special Meeting on Monday, November 16 of the Manassas City
Council, the Council voted "To allow the [City of Manassas] Utility
Commission to make a recommendation to the [Manassas] City Manager as
part of the FY 2011 Budget regarding the decision to continue offering
Internet service; additionally, staff was instructed to discontinue all
marketing and advertising of Internet service." This motion passed 4-2.
At the meeting, Manassas Director of Utilities Michael Moon told the
Council that "it is not cost-effective to continue the internet service
on the Main.net BPL communication system as a stand-alone cost center"
and that the City "need[s] to make the decision for internet service in
the context of what communication system will be used for the City's
AMI [Advanced Metering Infrastructure]." Read more here

Just curious, with this BPL stuff, everyone in the media is portraying it as specific to ham operators. Wouldn't it affect the shortwave broadcast bands too?

Yes, but it's kinda like the old "if a tree falls in the forest..." Who in the U.S. still listens to short wave broadcasts?

Its about time, especially with all of the other internet options available to business and residential customers at much higher speeds and reliability for not much more per month that BPL was charging in Manassas. I still remember the hype even back in the late 90's when I worked in corporate IT. Most of my counterparts were enamored with this technology but I was quite skeptical. I now work for a major worldwide ISP with legacy tied to Bell Labs. When I started at my current position, I mentioned BPL to one of the senior network engineers and she replied with a very loud "oh please,give me a break!!" I am speaking with almost thirty years of IT,telecom, and a brief stint at AM-FM broadcast engineering. The ISP I work for offers everything from T1's to 10GIG Ethernet connections to customers, it seems the rather slow(2-3mbits/sec on a good day with no arcing insulators) is hardly worth all that work to "clean up" power lines to make BPL even remotely feasible. The mentality of folks that are thrilled with BPL are the same ones that when you tell them you had to use some resistors to tie some leads high they reply "what's a resistor?" that would speak volumes.

Clearly they're giving up the city-run BPL system for economic reasons, not because of any "Battle of Bull Whatever" with the ARRL.

It does and the effect is horrible.
Just go to Mannheim (Germany) or Linz (Austria) and try listening to otherwise powerful European broadcasters on shortwave - a virtual impossibility.
