-snip-
Back when I was a young RF technician in my misspent youth I worked for
a little shop in Gaithersburg, MD called Norlin Communications.  We 
manufactured
mostly surveillance receivers for the US Govt.  If I remember correctly, 
Norlin was
owned by Astro Communication Labs, aka ACL.  I think both companies were owned
by Ayden Corporation, though I'm not positive.

I remember seeing old SR-209's coming into the test department where I worked
for repairs.  I fished one out of a dumpster out back one day with one 
plug-in RF
unit and worked on it at home but it never did work well, probably due to 
my lack
of decent test equipment at home.  Norlin turned out some interesting, if 
not spectacular
performing receivers, before going out of business sometime in the 
1980's.  I think
documentation, including schematics, might be still available at Ayden 
Corporation,
located in northern Virginia, in the DC area.  I'll have to rummage through 
my old
files if anyone expresses an interest.
