[Boatanchors] [Milsurplus] RBS Receiver

[WA5CAB at cs.com]

The final manual on RBS, RBS-1 and RBS-2 is NAVSHIPS 900,324 (reprint 
available).  Nomenclature wise, there are two receivers (CCT-46217 and 
CCT-46217-A) and three amplifier-power supplies (CCT-20235, CCT-20235-A and 
CCT-20235-B) between the three sets.  Electrically the two receivers are the same and 
the -A and -B power supplies are the same.  The base power supply differs 
from the -A and -B in that R-901 and R-902 are flat molded type units in it 
whereas in the -A and -B units they are tubular, mounted in fuse-clip type 
mounts.  Mechanically, the 46217 originally came in a vertical splash-proof 
bulkhead mounted cabinet with hinged front (top) cover while the 46217-A came 
with a mounting plate underneath for horizontal shelf or table top mounting.  
And Navy Type coaxial connector adaptor on the front panel mounted so as to 
hide the antenna and ground posts.  All three power supplies came in the 
same cabinet, with six shock mounts on top.  The -B model had a flat plate 
attached to the shock mounts which could in turn be attached to the bottom of 
the horizontal shelf.  

So, remove the receiver from the spash-proof cabinet or from the flat plate 
and if -A model remove the coax adaptor and without the nameplate, it can't 
be identified as to model or set.  The base model amplifier-power supply 
can be identified by the flat resistors.  But with only the six Lord shock 
mounts on top of the cabinet (no plate), the -A and -B models are the same.

At least so says the manual.  I've never seen one of the splash-proof 
cabinets, from which I surmise that when receivers were removed from ships for 
salvage, the cabinets were usually abandoned in place.
