14 2 INST ALLA TION AND CONNECTIONS ■ External antenna tuners and linear amplifier AH-4 ANT 1 Transceiver Coaxial cable (from the AH-4) To the AH-2b or an antenna element CONNECTING THE AH-4 The AH-4 can be used for the HF bands and 50 MHz band only.
15 3 FREQUENCY SETTING ■ When first applying power (CPU resetting) Before first applying power , make sure all connections required for your system are complete by referring to section 2. Then, reset the transceiver using the fol- lowing procedure.
16 3 FREQUENCY SETTING ■ VFO description VFO is an abbreviation of V ariable Frequency 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 switch (p.
17 3 FREQUENCY SETTING • Programmable tuning steps Programmable tuning steps are available to suit your operating requirements. These tuning steps are: • Independently selectable for 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 allows you to change the frequency in 1 MHz steps when rotating the main dial. This function is only available in FM, WFM and AM modes. ➀ Select FM, WFM or AM mode if necessary .
19 3 FREQUENCY SETTING • Quick band change function The quick band change function automatically stores the last frequency and mode used for each band in a band stacking register . This is convenient for contest operation, etc. The tables below show the quick band change default settings for each band.
20 4 RECEIVE AND TRANSMIT The IF shift function electronically changes the pass- band frequency of the IF (intermediate frequency) and cuts out higher or lower frequency components of the IF to reject interference. The function shifts the IF frequency up to ± 1.
21 4 RECEIVE AND TRANSMIT D Noise blanker The noise blanker reduces pulse-type noise such as that generated by automobile ignition systems. This function is not effective for FM modes or for 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 fi lter. Optional fi lter installation and selection tables SSB 23 4 RECEIVE AND TRANSMIT D Optional fi lter selection T wo optional fi lters can be installed in the IC- 706MKIIG. Narrow fi lters help reject interference from adjacent signals and obtain good selectivity .
24 4 RECEIVE AND TRANSMIT This function automatically attenuates beat tones, tuning signals, etc., even if they are moving. The automatic notch fi lter functions in SSB, FM and AM modes. ➀ Select S4 (DSP menu). • Push [DISPLA Y] 1 or 2 times when M or G is displayed.
25 4 RECEIVE AND TRANSMIT • Setting output power ➀ Push [DISPLA Y] for 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 power is displayed in 1 1 steps (L, 1 – 9 and H) but is continuously selectable.
26 4 RECEIVE AND TRANSMIT D Speech compressor The IC-706MKIIG has a built-in, low distortion speech compressor circuit. This circuit increases your average talk power in SSB mode and is espe- cially useful for DX ’ ing when the receiving station is having dif fi culty copying 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 variable capacitor angles are memorized as a preset point for 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 above). • 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 you to transmit and receive on two different frequencies. Split frequency operation uses 2 frequencies, one in VFO A and the other in VFO B. Following is an example of setting 7.057 MHz, CW mode in VFO A (for receive) and 7.
30 4 RECEIVE AND TRANSMIT D Repeater operation A repeater ampli fi es received signals and retransmits them at a different frequency . When using a repeater , the transmit frequency is shifted from the receive 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 received signals having a matching tone will open the squelch. Before communicating using tone squelch, all members of your party must agree on the tone squelch frequency to use.
32 4 RECEIVE AND TRANSMIT This function allows you to set repeater operation with the push of one switch. ➀ Push [ ( Y ) BAND]/[ ( Z ) BAND] to select the 28 MHz band. ➁ Rotate [DIAL] to select the operating frequency . ➂ Push [MODE] one or more times to select FM.
33 4 RECEIVE AND TRANSMIT D Connections for CW D CW operation ➀ Connect a paddle or straight key as above. ➁ Select CW (or CW å ) mode with [MODE]. ➂ Set CW break-in operation as semi break-in, full break-in or OFF . • Push [DISPLA Y] one or two times to select M , if necessary .
34 4 RECEIVE AND TRANSMIT D CW pitch control The received CW audio pitch and monitored CW audio pitch can be adjusted to suit your preferences (300 to 900 Hz) without changing the operating fre- quency . ➀ Push [MODE] one or more times to select CW mode.
35 4 RECEIVE AND TRANSMIT D Connections for RTTY (FSK) D Connections for AFSK Rear panel TU or TNC Personal computer Rear panel view Colors refer to connection to the supplied ACC cable. Use either the ACC or one of the two 1 / 8 ˝ plugs * 1 Connect SQL line when required.
36 4 RECEIVE AND TRANSMIT D RTTY (FSK) operation ➀ Connect a terminal unit as at left. ➁ Select RTTY (or å R TTY — see bottom of page) mode with [MODE]. ➂ Select the desired FSK tone/shift frequencies and keying polarity as below . ➃ Set the desired frequency with the main dial.

INST ALLA TION NOTES For amateur base station installations it is recom- mended that the forwards clearance in front of the an- tenna array is calculated relative to the EIRP (Effective Isotropic Radiated Power). The clearance height below the antenna array can be determined in most cases from the RF power at the antenna input terminals.
If the SP-7 external speaker is used with the IC-706MKIIG, please install the fer- rite supplied bead on the speaker cable, as shown below . • A ferrite bead and a cable fastener are supplied with IC-706MKIIG. INST ALLA TION NOTE: • Install the ferrite bead as near as possible the connecting plug.
