Bill,
Did you work the 13 Colonies event? 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).

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.

In many states, including Oklahoma and Texas, houses are customarily
built on slab and there is no basement or crawl space.

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.

Many of the newer locomotives are built with alternators. It's a

In my experience, an installer moves the pair serving a unit from the
common junction box to a normal demarc, either by extending the pair
from the common junction box, or by cutting it before it enters the
junction box. Or both. Sometimes, at the same time. If the next

Probably, whatever requires the least work on the part of the

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.

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.

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.
