15 3 FREQUENCY SETTING ■ When first appl ying power (CPU resetting) Bef ore first applying power , make sure all connections required f or your system are complete b y referring to section 2. Then, reset the transceiv er using the follo w- ing procedure.
16 3 FREQUENCY SETTING ■ VFO description VFO is an abbre viation of V ariable F requency Oscillator , and traditionally refers to an oscillator . The IC-706MKIIG’ s VFO can store a frequency and an operating mode. Y ou can call up a desired frequency to a VFO with the memo pad-read s witch (p.
17 3 FREQUENCY SETTING • Programmab le tuning steps Programmab le tuning steps are av ailable to suit y our operating requirements. These tuning steps are: • Independently selectable f or each mode • Selectable from 0.01 (FM/WFM/AM only), 0.1, 1, 5, 9, 10, 12.
18 3 FREQUENCY SETTING • 1 MHz quick tuning step The quick tuning step function allo ws you to change the frequency in 1 MHz steps when rotating the main dial. This function is only av ailable in FM, WFM and AM modes. ➀ Select FM, WFM or AM mode if necessar y .
19 3 FREQUENCY SETTING • Quick band c hange function The quick band change function automatically stores the last frequency and mode used f or each band in a band stacking register . This is conv enient for contest operation, etc. The tab les belo w show the quic k band change def ault settings for each band.
20 4 RECEIVE AND TRANSMIT The IF shift function electronically changes the pass- band frequency of the IF (inter mediate frequency) and cuts out higher or lower frequency components of the IF to reject interf erence . The function shifts the IF frequency up to ±1.
21 4 RECEIVE AND TRANSMIT D Noise blanker The noise blank er reduces pulse-type noise such as that generated b y automobile ignition systems. This function is not eff ectiv e f or FM modes or f or non pulse- type noise.
22 4 RECEIVE AND TRANSMIT D RF gain and squelch D Simple band scope The IC-706MKIIG uses the same control, [RF/SQL], to adjust one of either the RF gain or the squelch. [RF/SQL] adjusts either the RF gain or the squelch depending on the operating mode selected and the condition of the RF gain item in initial set mode (p .
Filter variations *Optional filter . Optional filter installation and selection tables SSB 23 4 RECEIVE AND TRANSMIT D Optional filter selection T wo optional filters can be installed in the IC- 706MKIIG. Narrow filters help reject interf erence from adjacent signals and obtain good selectivity .

25 4 RECEIVE AND TRANSMIT • Setting output power ➀ Push [DISPLA Y] f or 2 sec. to select quick set mode . ➁ Push [MENU] one or more times to select Q1 RF POWER . ➂ Rotate the main dial to select the desired output. • Output pow er is display ed in 11 steps (L, 1–9 and H) b ut is continuously selectab le.
26 4 RECEIVE AND TRANSMIT D Speech compressor The IC-706MKIIG has a built-in, lo w distor tion speech compressor circuit. This circuit increases your a ver age talk power in SSB mode and is espe- cially useful f or DX’ing when the receiving station is having difficulty cop ying your signal.
27 4 RECEIVE AND TRANSMIT The A T -180 automatic antenna tuner matches the IC- 706MKIIG to the connected antenna automatically . Once the tuner matches an antenna, the v ar iable capacitor angles are memorized as a preset point f or each frequency range (100 kHz steps).
28 4 RECEIVE AND TRANSMIT The AH-4 matches the IC-706MKIIG to a long wire antenna more than 7 m/23 ft long (3.5 MHz and abov e). • See p . 14 for connection. • See the AH-4 instruction manual for AH-4 installation and antenna connection details. NEVER operate the AH-4 without an antenna wire.
29 4 RECEIVE AND TRANSMIT Split frequency operation allows y ou to transmit and receive on tw o different frequencies . Split frequency operation uses 2 frequencies, one in VFO A and the other in VFO B. F ollowing is an e xample of setting 7.057 MHz, CW mode in VFO A (f or receive) and 7.
30 4 RECEIVE AND TRANSMIT D Repeater operation A repeater amplifies received signals and retr ansmits them at a diff erent frequency . When using a repeater , the transmit frequency is shifted from the receiv e fre- quency by an offset frequency .
31 4 RECEIVE AND TRANSMIT T one squelch operation is a method of communica- tions using selective calling. Only receiv ed signals having a matching tone will open the squelch. Bef ore communicating using tone squelch, all members of your party must agree on the tone squelch frequency to use.
