RADIOS AND MOUNTS

GENERAL
There are no simple methods for constructing field expedient radios. However,
signal flags, handsignals, flashlights, telephones,
and messengers can be used in
place of a radio.
When the receiver/transmitter is damaged, an auxiliary receiver
can be tuned to the proper frequency and used for reception.
