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

[Kammer George D Contr SMC DET 11 /MCL]

Good morning to the group!
As a prior USAF Security Service morse (and DF) type, I've followed some of
the links that have taken me back to where I put the R390, R390A, and the
Flair-9 to such extensive use.  And YES!...we DID call it the FLAIR-9 in
Anchorage,Alaska/Udorn, Thailand/San Vito, Italy.  The following links are
for your navigating pleasure.  The first is the USAFSS Web Ring, the second
is a great shot of the AN/FLR-9(V) at San Vito.  The third is the National
Security Agency site with a litany of information across the board.
Finally, for the "GRUNT" (Ground Roving Unit, Non-Trainable ... to us Air
Force types), the Army Security Agency web site is provided.

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.......
