For Scouting Planes.
The aircraft sets are for installa-
tion in the scouting planes that fly
over the devastated areas. All Of the
radio equipment is portable, and can
be quickly transported from place to
place. The field sets, transmitting in
code, can be heard about 100 miles,
while the aircraft sets have an even
longer range. All of the messages
handled will be in code, and will be
transmitted outside the broadcast
band, so that no interference will be
set up.
Picked radio men were assigned to
man the apparatus. Capt. Mclean
