[Milsurplus] SCR-536 for TD - Infantry comm

[WA5CAB at cs.com]

OK.  But you said the report was dated 09/42.  And it mentions the West 
Wall which is in Europe and not reached for another two years.  As far as I can 
tell from the Green Books, the only FM gear available at the time of 
Operation Torch (the landings in North Africa) was the SCR-293/294.  There is 
actually a Prewar preliminary manual on the SCR-508.  Why it at least wasn't 
available by the following year I don't know.  

The SCR-300 covers 40-48 MC.  The SCR-608 and SCR-610 top out at 38.9 MC.  
My guess is that it was the beginning of the three-band system (Armor, 
Artillery, Infantry) that continued up to around 1960.  If the BC-1000 had 
covered 38-46 MC, it would have worked.  Infantry could have talked to Artillery 
over 10 channels (380-389).
