[Milsurplus] SCR-300 and SCR-194 in Italy

[Hue Miller]

"The first large-scale test of the filament-type miniature tubes was 
provided by the SCR-300-A
in the invasion of Sicily. The records of tubes replaced in equipment used 
by combat divisions
during this campaign showed that despite the rough usage of battle service 
the tube replacements
for all reasons were less than three percent of the total number in service. 
The results firmly
established the ruggedness and dependability of the miniature tubes. "

"Miniature Tubes in War and Peace", N.H. Green, p. 331, RCA REVIEW, June 
1947

Does this (sort of) explain why we see SCR-194/ 195 having in the Italian 
campaign its only
known overseas combat use?

( Photos show its use also by U.S. Army in Iceland, noncombat role, and 
possibly other
areas also. )
