[. . . ] r Select menu item "27: HF1-MIN. " Key the transmitter, and confirm that the output power is 5 W (±1 W). In case the power is not within the specified tolerance, adjust this parameter for 5 W (±1 W) of transmission power. r The other RF power adjustment menus, [HF2-**] and [HF3-**], should be adjusted in the same manner as shown above for the 7 MHz and 21 MHz bands respectively. r Tune the transceiver to the 50 MHz band in the CW mode. Select menu item "36: 50M-MAX. " Key the transmitter, and adjust this parameter for 100 W (±5 W) of transmission power. r Select menu item "37: 50M-MID2. " Key the transmitter, and confirm that the output power is 50 W (±5 W). In case the transmission power is not within the specified tolerance, adjust this parameter for 50 W (±5 W) of transmission power. r Select menu item "38: 50M-MID1. " Key the transmitter, and confirm that the output power is 20 W (± 2W). In case the power is not within the specified tolerance, adjust this parameter for 20 W (±2 W) of transmission power. r Select menu item "39: 50M-MIN. " Key the transmitter, and confirm that the output power is 5 W (±1 W). In case the power is not within the specified tolerance, adjust this parameter for 5 W (±1 W) of transmission power. r Tune the transceiver to the 144 MHz band in the CW mode. Select menu item "40: VHF-MAX. " Key the transmitter, and adjust this parameter for 50 W (±2. 5 W) of transmission power. r Select menu item "41: VHF-MID. " Key the transmitter, and confirm that the output power is 20 W (±2 W). In case the transmission power is not within the specified tolerance, adjust this parameter for 20 W (±2 W) of transmission power. 18 Alignment r Select menu item "42: VHF-MIN. " Key the transmitter, and confirm that the output power is 5 W (±1 W). In case the power is not within the specified tolerance, adjust this parameter for 5 W (±1 W) of transmission power. r Tune the transceiver to the 430 MHz band in the CW mode. Select the menu item "43: UHF-MAX. " Key the transmitter, and adjust this parameter for 20 W (±1 W) of transmission power. r Select menu item "44: UHF-MID. " Key the transmitter, and confirm that the output power is 20 W (±0. 3 W). In case the transmission power is not within the specified tolerance, adjust this parameter for 20 W (±0. 3 W) of transmission power. TX Gain Adjustment r Select the USB mode. Inject a 1 mV audio signal at a frequency of 1 kHz from the AF generator into the MIC jack.
