EQUIPMENT INTERCONNECTIONS
Interconnections between this Amplifier and other
Heath equipment are shown in Pictorials 17 through
20 (Illustration Booklet, Pages 8 and 9). Other makes

NOTE: The ANT RELAY jack of the Linear Amplifier
must be grounded by the exciter to place the Linear
Amplifier into operation. (See the Circuit Descrip-
tion.) This grounding is accomplished by the VOX
relay or a transmit-receive switch in the exciter.
of equipment should be connected to the Linear
Amplifier in a similar manner.
Observe in Pictorial 20 that an external antenna relay
with extra contacts is necessary to obtain proper an-
tenna switching when you connect the Linear
Amplifier to transmitters that do not have a built-in
antenna relay.
