Hi Tom!

Suppose it just depends on who you decide to trust for accuracy.

If you look yourself up on wm7d.net, you'll see similar numbers but slight
variations again, hi hi.

At least while wm7d.net claims the numbers to be an approximation, they have
a known source that can't be disputed because it specifies Google is the
source there.

When I try to ask Siri about such things, my phone either suddenly becomes
hard of hearing, claims there is trouble with the connection, or offers to
read me something about latitude from Wikipedia, so guess it's no help at
all.

It is reported in some aps, such as Is It Dark, but I don't know how it
comes up with it.

I like the rendering in wm7d.net because it is expressed in degrees:
minutes: seconds, rather than a mysterious jumble of numbers that you
generally see expressed in an ap.

The accuracy is probably not as big of an issue in an hf contest genereally,
but it would certainly be more criticle in vhf and up contests, because
areas are more finely tuned there. All good grist for a mill though.

73,
Dave

Subject: Interesting Problem With N3FJP Logging Software

Hi, again, everyone.

 

As  I configured the logging software for the Stew Perry 160-meter CW
contest, I noticed an interesting problem concerning the latitude and
longitude coordinates for my particular location.

 

Typically, I always list my latitude and longitude according to the figures
given on qrz.com.  For my home QTH, they were listed as  43.69 lattitude,
and 85.49 longitude.  When I checked these coordinates with Siri on my
iPhone, they were listed as 43.7 lattitude, and 85.48 longitude.

 

In the setup screen for the N3FJP logging software, my coordinates are 2
degrees off, both for latitude and longitude.  I can't remember specifics,
but they are approximately 41 degrees latitude, and 83 degrees longitude.

 

I'm hoping that the QRZ.com coordinates are the most accurate, because those
are the ones I am listing. . But, I'm curious as to why this discrepancy
might exist.

 

Any thoughts????
