reading  the near to moderate distant fields.  BTW what
would be considered a  moderate distant field for AM 
N-DA systems? Over a  mile?



***************************************
 
Back when I was still doing this type of work,  you did walkins to  establish 
ground conductivity and NON-D radiation from the center of the array  out two 
miles every 0.1 mile.
 
Then we did from two miles out to 10-20 miles depending on if it was a new  
proof of a reproof or Skelton proof.  We did DA and Non-DA measurments and  
ratioed them immediately.
 
It was the opinion that the pattern formed outside the near filed and so DA  
measurements began at about two miles.
