[Boatanchors] Surplus Conversion Manual" Volume II

[WA5CAB at cs.com]

Same reason as for aircraft, to save weight.  The TBW was "portable".  
However, 800 cps apparently proved to be more trouble than the slight additional 
weight reduction offset.  I can't think of anything much after the TBW and 
GO-9 that required it.  Although there was a lot of equipment built that was 
rated to also run on it.
