Dave,

Additional info - The PE-110-C was built for the BC-669-C.  The BC-669 was 
originally the Hallicrafters HT-14, AM only and built for marine (meaning 
shipping, not USMC) use.  The Signal Corps bought it as SCR-543-A.  I have no 
information specifically on the HT-14 so I'm not certain that it included a civilian 
version of the PE-110-A or something different.  The Signal Corps added the 
PE-108-A gasoline powered 110 VAC generator, wooden operating cabinets, the 
RM-21-A Remote, and a vehicular type whip antenna using existing available parts. 
 

The -B and -C models are either the same as or nearly the same as the -A 
model.  In the -D model, CW operation was added, and they changed the cables, and 
the dimensions of the PE-110, which required a change to the cabinets.  
However, outside of the cabinets, all four models of radio, power supply and 
generator are functionally interchangable.

There was an MWO that effectively converted the BC-669-A through -C to the 
-D.  Nomenclature became BC-669-AM, -BM and -CM.  However, I don't think that 
many were done as I've owned or seen at least a dozen BC-669-A/B/C and none had 
been modified.
