S-14721XZ-C1Jun. 2011HF/VHF/UHF TRANSCEIVERThis service manual describes the latest technical information for the IC-9100 HF/VHF/UHF TRANSCEIVER, at the time of publication.NEVER connect the transceiver to an AC outlet or to a DC power supply that uses more than the specified voltage. This will ruin the transceiver.DO NOT expose the transceiver to rain, snow or any liquids.DO NOT reverse the polarities of the power supply when connecting the transceiver.DO NOT apply an RF signal of more than 20 dBm (100 mW) to the antenna connector. This could damage the transceivers front-end.To upgrade quality, any electrical or mechanical parts and internal circuits are subject to change without notice or obligation.MODEL VERSIONIC-9100[USA][EUR][EUR-01][ITR][ESP][TPE][KOR][CHN][FRA][EXP]Be sure to include the following four points when ordering replacement parts:1. 10-digit Icom part number2.

Make sure that the problem is internal before disassembling the transceiver.2. DO NOT open the transceiver until the transceiver is disconnected from its power source.3. DO NOT force any of the variable components. Turn them slowly and smoothly.4. DO NOT short any circuits or electronic parts. An insulated tuning tool MUST be used for all adjustments.5. DO NOT keep power ON for a long time when the transceiver is defective.6. DO NOT transmit power into a Standard Signal Generator or a Sweep Generator.7. ALWAYS connect a 50 dB to 60 dB attenuator between the transceiver and a Deviation Meter or Spectrum Analyzer, when using such test equipment.8. READ the instructions of the test equipment throughly before connecting it to the transceiver.REPAIR NOTESINTRODUCTION CAUTIONIcom, Icom Inc. and the Icom logo are registered trademarks of Icom

The resulting signal of phase comparison is rectied by D131 and D132, and composed and amplied by IC51, then applied to the A/D port of the tuner CPU (IC171).RESISTANCE DETECTION CIRCUITA portion of the TX signal is picked up by L151 and C152, and rectied by D152 to be converted into DC voltage.Another portion of the TX signal is rectied by D151 to be converted into DC voltage too. And these voltages are the same when the connected load (=antenna) is matched to 50 . Thus the difference of these voltages represents the resistance components.By compari ng the di fference of these vol tages, the transceiver detects the resistance components.The detected resistance components are buffered by Q151 and amplied by IC171, and then applied to the A/D port of the tuner CPU (IC701).CURRENT DETECTION CIRCUITA portion of the TX signal is picked up by L401, rectied by D401, and applied to IC431 to be level-compared with the voltage from the SWR detection circuit.When the resistance of connected load (=antenna) is less than 10 , the TX signal is bypassed the NETWORK UNIT, through the tuner compulsorily switches (RL301 and RL351), to protect the circuit on the NETWORK UNIT from reected waves.
