I believe that today is the last day of it. Our club (N5BL) worked all thirteen colonies and the William Penn SES (special events station). FYI, there are going to be two SESs operating for the final shuttle launch call signs N4S (Florida near the Cape) and N5S (New Mexico near White Sands) with the 'S' being for shuttle. They are both offering awards (either a QSL card or a certificate depending upon which way each of those stations decides to go). 73 (radiotelegraphy code that meant 'best regards'), Fred, WB4AEJ

Subject: Verizon confirms unlimited iPhone data plans no longer offered come Thursday Message-ID: <firstname.lastname@example.org> Verizon confirms unlimited iPhone data plans no longer offered come Thursday By Neil Hughes Starting Thursday, new smartphone customers with Verizon Wireless, including those who buy an iPhone, will no longer be able to purchase the carrier's unlimited data plan, AppleInsider has confirmed. This Thursday, July 7, is when Verizon will begin offering its "usage-based" billing for mobile customers, spokeswoman Debra Lewis said. The change will not affect current smartphone customers of Verizon. In addition, current smartphone customers who are upgrade-eligible will be allowed to move to another smartphone and retain their plan. But new customers or current customers who do not have a smartphone plan will only be able to buy a "usage-based" plan, Lewis told AppleInsider on Tuesday. ... http://www.appleinsider.com/articles/11/07/05/verizon_confirms_unlimited_iphone_data_plans_no_longer_offered_come_thursday.html

And in states where houses do have crawl spaces, concerns over the Hanta virus keeps many of us from ever crawling into them, no matter what.

Or both. Sometimes, at the same time.

FWIW, >cableTV lines are simply punched right through exterior walls. In our condo (112 units), it was run to the same junction box in each unit as RCN uses. When RCN was installed, they built a new node outside each building at attic level, and dropped into an upstairs closet in each unit, where a cheap plastic junction box supplied the new coax and twisted-pair lines to the bedrooms and living room. The original 1958 phone wiring follows a different route, parallel to the electrical supply, which runs through the basement. RCN (rightly) didn't want to deal with the original wiring, which doesn't follow any obvious path. -GAWollman -- Garrett A.

Why do we expect to be > taken care of when we are doing stupid stuff. It wouldn't surprise me at all if the customers (at least many of them) were not doing something stupid. A lot of "returned" drives may be returned because the customer is upgrading to a bigger drive, or is swapping drives because the old one is starting to not work correctly. Or, he's trading in a whole computer for a new one. Also, the store may use "spare" drives to temporarily hold user data for an OS upgrade onto the same drive, and the user may never know this. Either way, it's fairly common for a store's tech support to offer to copy customer data from one drive or system to another, either as part of the deal or for a modest fee. Microsoft offers software to do this (Windows Easy Transfer), and maybe they have more specialized, more automatic software for this job. Even with failing drives, much of the data can often be retrieved unless it's completely dead. You'd expect the customer to not wipe the drive: they'd lose their data. If they think to ask, tech support will say that the old data will be wiped off the old drive. I even see that mentioned on TV commercials as a selling point for a new computer: the upgrade is painless. If you're going to offer a service to copy customer data, it's irresponsible (and likely false advertising, as stores claim it's "safe and secure") to not follow through and wipe the old copy if the store is retaining, then reselling that drive.

That block is, for all legal purposes, the demarc. You own the wiring after it, they own the wiring before it. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis."

Not relevant. RF isn't a magnetic field, it's not an electrical field. It's both, and yet it does not act like either one. Near-field magnetic studies apply very well to the kind of magnetic leakage that comes off of a CRT, but really do not have any connection with RF. --scott -- "C'est un Nagra.
