[R-390] Re: R-390 digest, Vol 1 #922 - 2 msgs

DFing using the AN/FLR-9 Circular Array, (not Flair 9, but the mistake is 
understandible) was accomplished using, preferably, at least two other sites in 
order to triangulate the source emitter. A message would come over with a freq. 
An operator (usually 3 sitting the racks) would tune to the freq on the 
R-390, when the presentation on the big round scope was right, then you pushed a 
button that sent a message with the displayed bearing and frequency out over the 
net. My understanding was that this was VERY accurate. 
The antenna arrays were huge, occupying several acres. The one in the 
Philippines, where I was stationed, is still partially standing. The Philippinos used 
the largest antenna elements as flagpoles. Most of the other antennas are 
long gone, as are the bases where they were located.There were FLR-9 sites in 
Thailand, Alaska, Japan, and the Philippines that worked together to nail down 
the location of emitters in parts of Southeast Asia, and elsewhere. The range 
was very large.There were also sites in Italy, Germany, England, Turkey.  I 
believe the one in Alaska is still in use. 

The Navy employed a smaller but similar antenna system called the AN/FRD-10, 
they were located on many sites in the US, primarily along the coastline in 
places like San Diego, Ca; Skaggs Island, CA; Key West, FL; Chesapeake, VA; and 
up in Maine.

Ok, thats enough.......
