OT: QRZ.com "locations" caution

Someone wrote; " It is very simple to check the callsign on qrz.com and see
the qth."

This simply isn't true .... be careful!

Unless corrected by the licensee, the QRZ listing and everything about
it depends on the FCC-supplied data. If the "address of record" is a
P. O. Box, the location will depend solely on that information. This
includes the grid square, county and in some cases is many miles
the licensee's actual location.

Butte, MT is split between two grid squares, and I have a friend who's
P. O. Box address ... and QRZ info ... is in a different grid square from
where he lives and operates.

A case in point ... I'm the trustee of our club's call (W7VNE). As far
as anyone can recall it's -never- been on the air from it's QRZ location
-or- even county! Yet, it's been used in FD for over 40 years, but in a
different (and somewhat rare) county.

Things aren't always how they appear ...

73!

What Ken says is true, I live on the outer perimeter of the Wake Forest,
NC mailing area, and based on my mailing address, QRZ.com initially
listed me in grid square FM05 when I am actually in FM06 (FM06rb to be
more specific).
Yes, I changed it at QRZ,com, bot many others in a similar situation may
not change theirs.

Not only that - the centroid of a zip code can be in a completely
different grid than a large portion of the population. You'll
get close with the zip code but it will not be 100% reliable.

How true, Ken. I'll toss one out to you. Last year, I started digging into 10
digit grid squares. My shack is in a different square than my antenna, and
other antennas are in even different squares. ;o)

I truly believe there is a cartographic rule stating that any feature of
interest must be placed on the corner of the map :)

In addition, club calls start out with the trustee's address which could be
hundreds of miles away from the club's operating location. But change of
address transactions can change this relationship.

Also, some hams operate from multiple locations using the same call; me,
for example. When you work N6XI (or Filly Contest Group WF6C), you could be
working Santa Clara County CA CM87xg or Nevada County CA CM99wj. I do my
best to segregate my logs so my QSL responses can show where I was
operating.

Bottom line is, you really don't know where a US station is located unless
you ask the operator or receive a QSL (paper or electronic). LoTW supports
any number of locations. I think eQSL does, too.

Differences can be FAR greater than that. I'm chasing the CQ Field
award -- a Field is the first two letters of the grid. For MANY DX
listings, the default grid will be the geographic center of the COUNTRY,
which for large countries (for example, Australia, Russia, Brazil) can
be 1,000 miles from the actual QTH.

The good news is that qrz.com listings will tell you the source of the
grid info -- DXCC, geocoded, or user supplied. It's also possible to
take an address, or the name of a city/town, and get close. There are
also several websites that convert lat/lon coordinates to grids.
