[. . . ] r The other TX gain adjustment menus, "46: HF2TXG", "47: HF3TXG", and "48: 50MTXG", should be adjusted in the same manner as detailed above on the 7 MHz, 21 MHz, and 50 MHz bands, respectively. Select menu item "49: VHFTXG" and adjust this parameter for 35 W (±5 W) of transmission power. Select menu item "50: UHFTXG" and adjust this parameter for 10 W (±2 W) of transmission power. ALC Meter Adjustment r Tune the transceiver to the 21 MHz band in the USB mode. Select menu item "51: ALC-1. " Key the transceiver without microphone input and press the [A] key. Now, a value which the microprocessor computes will be displayed on the LCD. r Rotate the main dial to adjust this parameter to a reading four digits lower than the parame-ter value displayed in the previous step. r After setting the parameter, confirm that all the dots of the ALC meter have gone out. r Select menu item "52: ALC-M. " Inject a 4. 0mV AF signal at 1 kHz audio frequency from an audio generator and key the transceiver. r Press the [A] key and confirm that 9 dots of the ALC meter light up on the LCD. Reverse ALC Adjustment r Set the mode on CW, and connect a 150-Ohm dummy load to the antenna connector. r Key the transceiver on the 1. 8 MHz band, and select menu item "53: HF1-RV;" adjust this parameter for an "S-8" S-meter reading on the LCD. r The other reverse ALC adjustment menus, "54: HF2RV", "55: HF3-RV", and "56: 50M-RV", should be adjusted in the same manner as shown above on the 7 MHz, 21 MHz, and 50 MHz bands, respectively. r Key the transceiver on the 144 MHz band and select menu item "57: VHF-RV;" adjust this parameter for an "S-6" S-meter reading on the LCD. r Key the transceiver on the 430 MHz band and select menu item "58: UHF-RV;" adjust this parameter for an "S-3" S-meter reading on the LCD. Carrier Level Adjustment r Tune the transceiver to the 21 MHz band in the CW mode. r Set this parameter such that the center of the meter on the LCD lights up. r Connect the oscilloscope to the antenna connector via an appropriate attenuator. Select menu item "60: AM-CAR. " Inject a 1. 5 mV audio signal at a frequency of 1 kHz from the audio generator into the microphone jack. r Key the transceiver and adjust this parameter for 33% AM modulation on the oscilloscope. 19 Alignment FM Modulation Adjustment r Tune the transceiver to the 144 MHz band in the FM mode. Connect the FM linear detector to the antenna connector via an appropriate attenuator. Select menu item "61: DEV-W. " Inject a 15 mV audio signal at 1 kHz from the audio generator.
