if
an
SB-401
Transmitter
is used with a Model S13-301
Receiver for transceiving. The Transmitter includes
all
antenna switching relay.
Because of the heat generated by the tubes of the
Transmitter, it should be placed where adequate
air circulation is present. Donot place papers or
other objects under or on top of the Transmitter
as this would cut off air circulation through the
chassis.
