[ARC5] [Milsurplus] RAX-1 Contract Information

[WA5CAB at cs.com]

Further, the Airborne Radio Equipment Manual (AAF) dated 04/43, in the 
section discussing interchangability of equipment letter models, has this to 
say:

"It is imperative that planes scheduled for overseas operation have 
coverage of the 200-to 500-kilocycle band.  A directive was issued by this office 
on August 7, 1942, regarding this installation of BC-348-H receivers."

"this office" is Signal Section, Air Service Command, Patterson Field, 
Fairfield, Ohio.  BC-348-H was the first model with the added 200-500 KC band.  
Not mentioned in the pub is that BC-224-F (the 14 volt version of the 
receivers) was the first 224 so modified.
