(I am not a lawyer, and this is not legal advice. If you are in trouble with the FCC, I will give you the number to a good, FCC experienced attorney.)

 
       
       
  1. How accurate does my location data (latitude, longitude and elevation) have to be to stay out of trouble with the FCC?  
       
  2. If my coordinates for my license are wrong, but only a little, is that OK?  
       
  3. I am licensing a system on someone else's tower, and their ASR (Antenna Structure Registration) data is incorrect.  What should I do?  
       
  4. I have been licensed on an ASR registered tower for years, but now I find that the tower owner has different coordinates and/or elevation data for the tower, that doesn't match my license.  Should I be worried?  
       
  5 How is HAAT (Height Above Average Terrain) calculated?  
       
  6. How can I convert NAD27 to NAD82 and back?
