INSTRUCTION MANUAL i706MK™G HF/VHF/UHF ALL MODE TRANSCEIVER This device complies with Part 15 of the FCC rules. Operation is sub- ject to the following two conditions: (1)This device may not cause harmful interference, and (2)this device must accept any interference received, including interference that may cause undesired operation. EXPLICIT DEFINITIONS PRECAUTIONS IMPORTANT Read this instruction manual carefully before attempting to operate the transceiver. Save this instruction manual. This instruction manual contains important safety and operating instructions for the IC-706MKIIG. RWARNING HIGH VOLTAGE! NEVER attach an antenna or internal antenna connector dur- ing transmission. This may result in an electrical shock or burn. RNEVERapply AC to the [DC13.8V] socket on the transceiver rear panel. This could cause a fire or ruin the transceiver. RNEVERapply more than 16 V DC, such as a 24 V battery, to the [DC13.8V] socket on the transceiver rear panel. This could cause a fire or ruin the trans- ceiver. RNEVERlet metal, wire or other objects touch any internal part or connectors on the rear panel of the transceiver. This will cause electric shock. RNEVERexpose the transceiver to rain, snow or any liquids. NEVER allow children to play with the transceiver. AVOID using or placing the transceiver in areas with temperatures below –10°C (+14°F) or above +60°C (+140°F). Be aware that temperatures on a vehicle’s dashboard can exceed 80°C, resulting in permanent damage to the transceiver’s front panel if left there for extended periods. AVOID placing the transceiver in excessively dusty environments or in direct sunlight. AVOID placing the transceiver against walls or putting anything on top of the transceiver. This will obstruct heat dissipation. During mobile operation, DO NOToperate the trans- ceiver without running the vehicle’s engine. When transceiver power is ON and your vehicle’s engine is OFF, the vehicle’s battery will soon become exhausted. Make sure the transceiver power is OFF before start- ing the vehicle. This will avoid possible damage to the transceiver by ignition voltage spikes. During maritime mobile operation, keep the transceiv- er and microphone as far away as possible from the magnetic navigation compass to prevent erroneous indications. BE CAREFUL! The heatsink will become hot when operating the transceiver continuously for long periods. BE CAREFUL!If a linear amplifier is connected, set the transceiver’s RF output power to less than the lin- ear amplifier’s maximum input level, otherwise, the lin- ear amplifier will be damaged. Use Icom microphones only (supplied or optional). Other manufacturer’s microphones have different pin assignments and connection to the IC-706MKIIG may damage the transceiver. Beat signals may be heard on some frequencies. These will occur as a result of circuit construction. For U.S.A. only Caution:Changes or modifications to this transceiver, not expressly approved by Icom Inc., could void your author- ity to operate this transceiver under FCC regulations. The explicit definitions described below apply to this instruction manual. The IC-706MKIIG Europe version complies with essential requirements of the 89/336/EEC direc- tive for Electromagnetic Compatibility under the conditions listed below. This compliance is based on confor- mity with the European harmonized standard ETS300 684 Jan. 1997 (EMC product standard for Commercially Available Amateur Radio Equipment). Condition: •In combination with PS-85 •When connected to a power supply via OPC-639 WORDDEFINITION RWARNING Personal injury, fire hazard or electric shock may occur. CAUTION Equipment damage may occur. NOTE If disregarded, inconvenience only. No risk of personal injury, fire or electric shock.

Operational Description

1 RECEIVER CIRCUITS 1-1 HF/50 MHz RF CIRCUIT (FILTER, MAIN AND HPF BOARDS) HF/50 MHz RF filters pass only the desired band signals and suppress any undesired band signals. The HF/50 MHz RF circuit has 7 low-pass filters and 7 high-pass filters for specified band use. HF/50 MHz RF signals from the [ANT1] connector, pass through one of 7 low-pass filters as below, the transmit/ receive switching relay (FILTER unit; RL1) and low-pass filter (FILTER unit; L1, L2, C1-C5), and are then applied to the MAIN board via J1 (FILTER unit). The signals from the FILTER board are applied to or bypass the 20 dB attenuator (R122, R125, R126). The signals pass through the high-pass filter (L132, L133, C132-C137) to suppress strong signals below 1.6 MHz and are then applied to the HPF board via the “TOAT” terminal. (1) 0.03-2 MHz and 30-40 MHz The signals pass through a low-pass filter (L101, L102, C101-C105), and then applied to the preamplifier circuit on the MAIN board. (2) 2-30 MHz The signals from the low-pass filter (L101, L102, C101-C105) are applied to one of 6 high-pass filters as at right above and are then applied to the preamplifier circuit on the MAIN board. (3) 40-60 MHz The signals pass through the low-pass filter (L172, L173, C172-C176) and the high-pass filter (L174, L175, C177-C181) via D171 and are then applied to the preamplifier circuit on the MAIN board. 1-2 VHF AND UHF RF CIRCUIT (PA UNIT) The VHF and UHF RF circuit passes and amplifies only the desired band signals and suppresses any undesired band signals. The VHF RF circuit has a preamplifier and band-pass filters. The VHF RF signals from the [ANT2] connector pass through the low-pass filter (L263, L264, L265, C274-C277) and antenna switching circuit (D261, D291, D292, D293). The signals are amplified at the preamplifier circuit (Q403) between the band-pass filters (D406, D407 and D410). The UHF RF signals from the [ANT2] connector pass through the high-pass filter (L316, L317, C326- C327), pass through the low-pass filter (L314, L315, C322-C325) and antenna switching circuit (D341, D342, D343). The signals are amplified at the preamplifier circuit (Q453) between the band-pass filters (D454, D456). The filtered signals are applied to the MAIN board via J481 (PA unit) and are then applied to the preamplifier circuit. 1-3 PREAMPLIFIER CIRCUIT (MAIN BOARD) The preamplifier circuit in the IC-706MKIIG has approx. 15dB gain over a wide-band frequency range. When the preamplifier is turned ON, the signals from the RF circuit are applied to the preamplifier (IC151) via D2182. Amplified or bypassed signals are applied to the 1st mixer circuit (D271). 1-4 1ST MIXER CIRCUIT (MAIN BOARD) The 1st mixer circuit mixes the receive signals with the 1st LO signal to convert the receive signal frequencies to a 69 or 70.7 MHz 1st IF. The signals from the preamplifier circuit, or signals which bypass the preamplifier, are applied to a low- pass filter and then to the 1st mixer (D271). The 1st LO signals (69.0415-539.0115 MHz) enter the MAIN board from the PLL unit via J281. The LO signal is amplified at IC-281, filtered by a low-pass filter, and then, applied to the 1st mixer. 1-5 1ST IF CIRCUIT (MAIN BOARD) The 1st IF circuit filters and amplifies the 1st IF signals. The 1st IF signals are applied to a Crystal Filter (FI511) to suppress out-of-band signals. The 69 MHz 1st IF signals (except WFM) pass through the crystal filter (FI511), however, the 70.7 MHz 1st IF signal (WFM) passes through a band-pass filter (L501-L504, C501-C506). Then the filtered signals are applied to the IF amplifier (IC281). The AGC voltage is supplied to the transmit/receive switching circuit (D521, D522) and D521/D522 function as PIN attenuators for AGC operation. The amplified signals are then applied to the 2nd mixer circuit (D551) via the band-pass filter (L542-L546, C542-C545). 1-6 2ND MIXER CIRCUIT (MAIN BOARD) The 2nd mixer circuit mixes the 1st IF signals and 2nd LO signal (60.00 MHz) to convert the 1st IF to a 2nd IF. The 1st IF signals from the band pass filter (L542-L546, C542-C545) are converted to 9 MHz or 10.7 MHz 2nd IF signals at the 2nd mixer (D551). The 2nd IF signals are applied to the band-pass filter (FI561) to suppress undesired signals, such as the 2nd LO signal, and are then applied to the noise blanker gate (D561, D562). While in WFM mode, the IF signals pass through the low-pass filter (L601, C601-C603), IF amplifier (Q601), ceramic filter (FI611) and IF amplifier (Q611). The signals are then applied to the WFM demodulator circuit (IC631). 1-7 NOISE BLANKER CIRCUIT (MAIN BOARD) The noise blanker circuit detects pulse type noise, and turns OFF the signal line when noise appears. A portion of the signals from FI561 are amplified at the noise amplifiers (Q621, Q638, amplifier section of IC631), then detected at the noise detector (D632) to convert the noise components to DC voltages. The converted voltages are then applied to the noise blanker switch (Q634, Q635). At the moment the detected voltage exceeds Q634’s threshold level, Q635 outputs a blanking signal to close the noise blanker gate (D561, D562) by applying reverse-biased voltage. The detected voltage from D632 is also applied to the noise blanker AGC circuit (Q631, Q633) and is then fed back to the noise amplifier (IC631) as a bias voltage. The noise AGC circuit prevents closure of the noise blanker gate for long periods by non-pulse-type noise. The time constant of the noise blanker AGC circuit is determined by R637. The 2nd IF signals from the noise blanker gate are then applied to the 2nd IF circuit. 1-8 2ND IF CIRCUIT The 2nd IF circuit amplifies and filters the 2nd IF signals. The 2nd IF signals from the noise blanker gate (D561, D562) are amplified at the IF amplifier (IC571) via the Tx/Rx switch (D572) and applied to a 2nd IF filter as shown below. The filtered or bypassed signals are applied to the buffer amplifier (Q721), IF amplifiers (Q731, Q741) and buffer amplifier (Q751) to obtai…
