[time-nuts] information about the Austron Synchronous Filter 2090A

[Ruslan Nabioullin]

Hi, any ideas on what the Austron Synchronous Filter 2090A is for?  I 
couldn't find it in the '88 catalog.  I recall seeing some hits for it 
in old unclassified DoD R&D publications in the past, wherein it was 
used as part of an experimental LORAN reception setup.
