  Question: If my coordinates for my license are wrong, but only a little, is that OK?  
     
  Answer: Maybe.  Maybe not.  Read my answer to Tech question 1. The FCC licenses Private Land Mobile Radio Service (PLMRS) systems based on many factors, but primarily on the relationships between the location, elevation, power and frequency of each system in relationship to all others.  If you are operating a system at a location where it is not licensed, each of these factors would have to be re-evaluated to determine whether or not you are violating FCC rules, and causing interference to other users.

As well, there is a legal question of whether or not you even still HAVE a license.  If you did not construct your system in accordance with the license originally granted you by the FCC, then you may not have met the construction requirements, and your license would legally be void.  Lawyer time, fast.

If you moved it after construction, then your original license does not cover operations at the new location or elevation, and you are in trouble again. The fines for operation at an unauthorized location can be steep.

If you simply made a minor error when determining the coordinates of the system, and the rest of the data (especially the transmitter address) is correct and accurate, then you may be ok, but you still need to correct the license.  In the past, the FCC has attempted to be reasonable in making a determination whether or not you are in trouble and whether or not to fine you (or how much to fine you).  During the 800 MHz Finder's Preference program, they made a determination for that program that they would generally consider any system that was operating within 1.6 kilometers of the licensing location as substantially operating within it's licensed parameters.  But each incident must be evaluated on a case by case basis.  If you intentionally or knowingly constructed at a location other than your licensed location, then you are definitely in trouble.

It is better to be safe.  If you are not currently constructed and operating within feet of your current authorization, you should apply for either a modification of your current license to bring it into compliance, or apply for an entirely new license at the correct location.
