Accuracy question

[edbett]

Thanks so much for the great explanation and recommendations.  Yes, the comparison with lightningmaps gives me a much better picture and understanding of the differences/similarities and cautions.  I just recently learned of these sites and am quite impressed with the number of stations worldwide and their contributions.  As an old, long retired electronics manufacturer I have even considered setting up a station, but it is more of a challenge than I wish to take on now!  Thanks again for your help..
