[Milsurplus] HRO

[Tom Brent]

This past weekend I acquired another National HRO receiver (factory painted
RCAF blue) and that prompted me to remember a question I have been meaning
to ask this learned group for quite some time.

It is common knowledge that the HRO series was ordered in large quantities
for intelligence monitoring purposes and in recent years I have come across
a number of online and written sources that refer to it as *"the premier
signals intercept receiver available during World War II"*.  Was this truly
the case or had it simply gained a reputation in the mid to late 1930's
that stayed with it even though better receivers came along before and
during the war?

This is not an effort to slam the HRO but rather an attempt to gain a more
accurate understanding of its place in military communications history.

Your thoughts would be appreciated!

Tom
