NOTE: The OPC-118 interface cable to connect
the IC-2K L to the IC-735 must be
purchased separately.

The IC-735 is designed to operate into a 50 ohm impedance load.
Therefore, any amplifier used must have a 50 ohm input impedance
for best efficiency.
The optional 500 watt, solid-state IC-2KL linear amplifier may be
easily connected to the IC-735 with the cables supplied with the
amplifier in the same way as other ICOM transceivers. Refer to the
the IC-2KL Instruction Manual for details.
The connections are shown below.

USING OTHER MANUFACTURERS'
LINEAR AMPLIFIERS
The SEND jack on the rear panel of the transceiver supplies the
output from a built-in keying relay for a linear amplifier. The ALC
jack is an input for the automatic level control signal from a linear
amplifier.
The specification for the keying relay is DC 24 volts maximum. Do
not exceed this limit. If the transmit/receive circuit of the linear
amplifier requires greater voltage than the above value, a larger relay
must be installed between the amplifier and the transceiver.
The SEND jack is grounded while the transceiver is in the transmit
mode and it opens when the transceiver returns to the receive mode.
The output condition of this jack does not control either the trans-
mit or receive function of the transceiver.
