EQUIPMENT INTERCONNECTIONS
Interconnection between this Amplifier and a typical
transceiver is shown in Pictorial 9-4 (Illustration
Booklet, Page 64). Many brands of equipment usually
follow this same general pattern.
RF IN — Connect this socket to the RF output
connector on your transmitter.
RF OUT — Connect this socket to the cable coming
from your Antenna.
NOTE: Use shielded cable, such as audio-type cable,
for the following connections.
RELAY — Connect this socket to the Relay socket on
your transmitter. This connector requires contacts
that are normally open in the receive mode and
closed in the transmit mode. If your transmitter does
not have this switching provision, you will have to

use some other means. If you have separate coaxial
transmit-receive relay in your station, it may have
external contacts available. You could also use a sep-
arate switch. The OPR/STBY switch on the front of
the Amplifier must be set to OPR before the Amp-
lifier’s internal relay will operate.
NOTE: Some transceivers contain a transistor switch
that does not close to a ground potential. If your
transceiver is of this type, use an external relay to
activate the relay inside the Amplifier.
ALC OUT — Connect this socket to the ALC input of
your transmitter. A 0 to 20-volt negative ALC
voltage is present at this socket. Refer to your trans-
mitter manual for proper connection information.
The ALC ADJ control setting procedure is outlined in
the "Operation" section of this Manual.
+12 VDC — Use this socket to power an accessory,
such as an “on-the-air" light, etc. Approximately
+12 VDC at 100 milliamperes is present at this sock-
et.
