SECTION 3 SYSTEM INTERCONNECTIONS 3 1 LINEAR AMPLIFIER transceivers Refer to the IC 2KL Instruction Manual for THE IC 735 is designed to operate into a 50 ohm impedance details load Therefore any amplifier used must have a 50 ohms input impedance for best efficiency USING THE IC 2KL LINEAR AMPLIFIER The optional 500 watt solid state The connections are shown below NOTE The OPC 118 interface cable to connect the IC 2KL linear IC 2KL to the IC 735 must be purchased amplifier separately may be easily connected to the IC 735 with the cables supplied with the amplifier in the same way as other ICOM SUPPLIED WITH OPC 118 AVAILABLE SEPARATELY IC 2KL TO ANTENNA ACC CABLE D COAXIAL CABLE SUPPLIED WITH IC 2KL C 2KL o O TO IC 2KLPS EARTH GROUND circuit of the linear amplifier requires greater voltage than USING OTHER MANUFACTURERS LINEAR the above value a larger relay must be installed between the AMPLIFIERS The SEND jack on the rear panel of the transceiver supplies amplifier and the transceiver the output from a built in keying relay for a linear amplifier The ALC jack is an input for the automatic level control The SEND jack is grounded while the transceiver is in the signal from a linear amplifier transmit mode and it opens when the transceiver returns to the receive mode The output condition of this jack does not The specification for the keying relay is DC 24 volts maximum Do not exceed this limit If the transmit receive TO ANTENNA control either transceiver the transmit or receive function of 50 OHM COAXIAL CABLE IC 735 3 2 ANTENNA TUNER IC AT500 antenna tuners as shown in the diagram In order to have the IC 735 perform to optimum capability it is recommended that the ICOM AT 150 automatic antenna All three models have automatic band changing controlled tuner be used between the transceiver and antenna system by a voltage supplied from the IC 735 See page 3 5 for more information The IC 735 may also be used with the earlier IC AT100 or 3 1 the
