[Milsurplus] L.O. radiation

[Hue Miller]

Very similarly worded ads appear in Nat'l Geographic magazines of
1942.

I have somewhat a lesser regard for Japanese WW2 radio df efforts. I don't see the evidence 
that Japan was well equiped, or even equiped, with mobile DF equipment. This is from looking
thru the relevant TM-E manuals on Japanese equipment and also seeing a bunch of it (in
these postwar years. ) On the other hand, Germany did have quite a range of DF equipment,
from truck mobile assmblies down to sets hidden on a searcher's body.
I believe that Japanese DF procedure, at least in the case of the measures against coast-
watchers, was to discover the radio traffic, then to DF it via fixed point monitoring stations,
or from ships, then to send out search parties to search out likely camping places for the
multiple-person coastwatcher crew - and to try to coerce or reward any natives for information.
With the vegetation so thick, there's only so many places you can hide a whole crew with their
bulky equipment, and you have to stick to the trails.
( The Ghost of Guam survived because he had only himself to hide from the Japanese, and even
then, he came close to capture a number of times. )

One of those books i read when i was trying to learn more about SACO claims the Navy men
operated a radio station a block away from Japanese quarters in their town. That hardly seems
likely, doesn't it? Well, maybe so, with just a slight exageration.  ( and BTW, it was more than
likely a TBX, and NOT a CMS, MBM, or PRC-x )
