Ken,
I think I may have what you need inasmuch as  I have all the military 
ARN-30, 30D, and Type 12 manuals as well as the original ARC factory 
book for the Type 12 series.  For a number of years I collected Type 12 
equipment.  All I have left now are a few pieces.  Where's it all 
gone.....?  But, to your query, yes the R-11( ) covers the LF beacon 
band.  The R-13( ) is ARC Type 15 series equipment,  and covers the VHF 
Nav-Com band of 108-136 MHz.  This receiver is the same as the ARN-30 
(not "D") R-445 receiver.  The R13 and the R-445 are similar to the Type 
12 R-15 except that the connectors on the aforementioned come out the 
back, vice the front panel.  I think I can copy the schematic for the 
R-445 for you but in sections as that one is a fold out..  I understand 
that the Type 12 R-22 covered the BC band but my books do not include it 
nor have I ever had/seen one.  The other LF/BC band receiver unit was 
the ADF that ARC made as the ARN-59 or the commercial  ARC Type 21A... 
as I recall.
