Early on  some ground IFF systems were given RC numbers, maybe for security 
or  something else, I'm not sure.  They were "add-ons" to existing radars 
and  
often varied in detail depending on the associated radars.  Their  
individual 
units always had the familiar BC , PS, etc nomenclatures.   Eventually as 
they were upgraded and modified some grew in the AN system  such as the 
AN/CPX-1.  The RC numbers that I previously listed are  the correct 
nomenclature for your device.  I believe that I have the  TM's for it.
