[BC] GPS for Proofing (WAS:dBm, dBc, dBd)

[Neal Newman]

 Hi Alan 
thats what I did with the delorme atlas 2006 maps... I took the pointer 
from the transmittersite and drew out lines( radials) out to the 15km 
Point....  then zoomed in and Flagged points along the radials  where it 
crossed near intersections . the GPS is not that accurate But it Gets 
you to the Points . I have found that on some days the GPS is correct 
and other days  its off by 100 feet  but  the intersections dont move.. 
so  I take the readings where the radial crosses that intersection..
 with the War going On  I think Our Govt plays with the Error rate on 
the GPS Birds.. Only a Surveyers  GPS  is dead on accurate. and I 
believe  they sign a waver with the Govt  to use them??( military specs 
on a surveyers GPS for accuracy)thats why they are so expensive.
 Otherwise  Its the old standard  look for telepone pole # 45675ED     
at intersection of church and broom streets. then go 20 feet across 
street from pole on west side of road..  LOL
 been to alot of places over the years  where the Old Barn is now 
missing   and its a golf course
the best one was monday  the road ended... but continued into the woods 
500 feet between the  end of the road and the Interstate. the point was 
250 feet in from the interstate.. Pulled out the 500 foot tape rule and 
walked  in 250 feet to take the reading..  If I didnt do that  there 
would be 4km between the Points I needed Every 2km..   that was the only 
Oddball point..
 the 330 degree was the easy one  this road  was a giant sinewave... The 
radial crossed it 7 times. and exactly at intersections.. So we took the 
Points at the 7 corners..'
I guess its easy on a new install  Because you can make up all the 
points new from scratch
