Tom,
Thank you for the information... I have updated my square on qrz.com. Now, having shaken my faith in the available automated data, I'm going to have to visit a GIS site to verify my exact Lat/Long... ;^}} Dave G.

Example, I am in FM06, but my mailing address places me in FM05.

The only way to know where you really are with perfect accuracy is to get a
correct Lat/Long coordinate set and convert this to Maidenhead. GPS receivers can be set to read out directly in six-character Maidenhead, so if you have a GPS, use that to determine your correct grid locator directly. QRZ and other sites typically use the location of your zip code to compute your grid locator, as this data is readily available from the USPS. While this will almost always produce a correct grid square to four characters (not six), it often fails even four characters when a station is near the grid boundary.

You can also get Lat/Long from Google Earth, which is fairly accurate
these days in the areas where they have high resolution photography.

As I mentioned in my Salmoncon talk this weekend, the Maidenhead Locator System has one and only one official map datum. That is the World Geodetic System 1984, typically abbreviated WGS84 on GPS receivers. If you have a GPS receiver, make sure the datum is set up that way when determining your Maidenhead coordinates. That's the best way to determine your Maidenhead coordinates accurately. The 1:24 000 topographical mapping series in the USA uses a different datum: North American Datum 1927 Continental US. If NAD27 is used with Maidenhead, inaccuracies will result. As the name implies, that datum does not apply to the whole earth. Since the MLS is intended to cover the whole earth, it's more appropriate to use a geodetic standard that also models the whole earth. There is another source of inaccuracy in some computer programs: If the input is a street address, the result is an approximation based on an interpolation of address numbers. 73, Bruce N7RR J.
