iIMPORTANTREAD ALL INSTRUCTIONS and on-line help care-fully and completely before using the receiver.SAVE THIS INSTRUCTION MANUAL — Thisinstruction manual contains important operating instructionsfor the IC-PCR1000 COMMUNICATIONS RECEIVER FORCOMPUTER.USE antenna(s), such as a well-matched 50 Ω antenna andfeedline. For radio communications, the antenna is of criticalimportance, along with sensitivity.SYSTEM REQUIREMENTS• IBM PC compatible computer• An RS-232C serial port (38400 bps or faster)• Microsoft ® Windows ® 95 or Microsoft ® Windows ® 3.1 withappropriate DOS• Intel i486DX4 processor or faster (Pentium® 100 MHz or fasterrecommended)• At least 16 MB RAM• At least 10 MB of hard disk space• 640 ✕ 480 pixel display (800 ✕ 600 pixel display recommended)FEATURES• USER-SELECTABLE INTERFACEUsers can choose from 3 different operating screens de-pending on their ability level and preference.• WIDE FREQUENCY RANGE, MULTI-MODE RECEIVEThe IC-PCR1000 has a wide frequency coverage from 0.5MHz to 1300 MHz* with all mode receive capability.* Some frequency ranges are restricted depending on version.• IF SHIFTThe IF shift function is effective in SSB mode for reducing in-terference from nearby signals. It does so by electronicallyshifting the passband of the IF filter.• REAL-TIME BANDSCOPE FUNCTIONThe real-time bandscope function makes it easy to find busyfrequencies and also easy to observe receive frequency bandconditions. The maximum band width is ±200 kHz.• NOISE BLANKER • VSC (Voice Scan Control) FUNCTION• S-METER SQUELCH • HIGH PERFORMANCE PLLCIRCUIT • A VARIETY OF TUNING STEPS • A VARIETY OFSCANS • DIGITAL AFC CIRCUITVersions of the IC-PCR1000 which display “CE” on the serialnumber seal, comply with the essential requirements of the89/336/EEC directive for Electromagnetic Compatibility.
