[. . . ] u Push [FM] to cancel the duplex operation mode. · "DUP­" and "T" indicators disappear. FM VFO A D Setting tone frequency (except Europe, Sweden and Italy versions) q Push [M/S·BAND] to select the desired frequency band. w Push [SET] then [FM] to enter the FM set mode. e Push [DN M] or [L UP] to select the tone frequency item. · "ton, " selected band (144/430(440)/1200) and "T" indicator appear. D Setting offset frequency q Push [M/S·BAND] or [SUB] to select the desired frequency band. w Push [SET] then [FM] to enter the FM set mode. e Push [DN M] or [L UP] to select the offset frequency item. · "duP" and selected band (144/430(440)/1200) appear. r Rotate the tuning dial to set the desired tone frequency. t Push [FM] to exit from the FM set mode. r Rotate the tuning dial to set the desired tone frequency. t Push [FM] to exit from the FM set mode. 35 5 RECEIVE AND TRANSMIT I SSB mode operation q Push [M/S·BAND] to select the desired frequency band. w Push [SSB/CW] to select USB or LSB mode. · Push [SSB/CW] for 1 sec. to switch between USB and LSB when either the USB or LSB has been selected. [TRANSMIT] [M/S·BAND] [SSB/CW] e Rotate the tuning dial to set the desired frequency. r Push [PTT] to transmit and speak into the microphone at a normal voice level. t Rotate [MIC GAIN] so that the MAIN band indicator periodically lights red brightly. · The brightness increases when the ALC is activated. [MIC GAIN] Tuning dial y Release [PTT] to receive. ALC indicator While transmitting, the MAIN/SUB band indicator shows the ALC condition. Brightness increases more than usual when the ALC function is activated. VOX function The VOX (Voice-operated Transmission) function is available for switching between transmit and receive with your voice. 33 for details. I Speech compressor The speech compressor increases average RF output power, improving signal strength and readability in SSB. The IC-910H has a built-in, low-distortion speech compressor circuit. Push [COMP] to turn the speech compressor ON and OFF. · Either USB or LSB should be selected. · "COMP" indicator appears when the speech compressor is activated. MAIN band LED [COMP] lights in red while transmitting. D Compression level setting q Select USB or LSB mode. w Preset the transceiver as follows: [COMP] function : OFF [RF POWER] control : Max. counterclockwise e Transmit at your normal voice level. r Adjust the [MIC GAIN] control so that the MAIN band indicator periodically lights red brightly whether or not you speak softly or loudly. t Push [COMP] to turn the speech compressor ON. [. . . ] You can change frequencies, operating mode, memory channels, etc. AG-25 (for 144 MHz band), AG-35 (for 430(440) MHz band), AG-1200 (for 1200 MHz band) WEATHER-PROOF PREAMPLIFIERS External all-weather, mast mounting preamplifiers for compensating for coaxial cable loss. UT-102 VOICE SYNTHESIZER UNIT Announces the receive frequency, mode and S-meter level in a clear, electronically-generated voice, in English (or Japanese). AG-2400 DOWN CONVERTER UNIT All-weather, satellite down converter with superior NF and gain. Input freq. : 2400­2402 MHz, Output freq. : 144­146 MHz Conversion gain: More than 25 dB Total NF: Less than 1. 5 dB 81 IC-MB5 MOBILE MOUNTING BRACKET Transceiver mounting bracket for mobile operation. SP-7 EXTERNAL SPEAKER Compact speaker for base station operation. 16 INSTALLATION NOTES Forward clearance, EIRP by frequency band Watts 10­2 m 70 cm 23 cm 13 cm and above 100 2m 2m 1. 1 m 0. 7 m 1000 6. 5 m 6m 3. 5 m 3m 10, 000 20 m 18 m 11 m 7m 100, 000 65 m 60 m 35 m 29 m For amateur base station installations it is recommended that the forwards clearance in front of the antenna 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. [. . . ]
