Some Trivia, but in the pre-war days the Sig Corps put out an urgent
request for the hams to donate radios to the war effort.
Many different makes and models went to war.  An acquaintance of
mine, deceased long ago,  was a radio operator in North Africa, US Army,
and related to me how some of the radios they used had ham call signs
etc on them.  Someone probably has more input on this subject.

Look at the huge number of HRO-M the British bought. Thinking of pre war receivers things like the  RAB come to mind. That being maybe the biggest receiver ever produced and the RAK and RAL also being way larger and heavier and more than likely cost more. After 1940 things like the RAB/RAK/RAL may have been better but still way more complicated to use for a simple task like intercept. I do not think the SX-28 and the Super Pro were available for military use before 1940/41 and the question was what would have been in use in pre war Philippines for intercept service. Of all the HRO family the RAS is probably the worst with its low IF and issues with images and as far as knowing or setting frequencies cannot imagine any operation without a frequency meter so direct display was not a issue.
