RF Power Adjustment
18: HF1-IC." 18: HF1-IC 18: HF1-IC Tune the transceiver to the 1.8 MHz band in the CW
18: HF1-IC
mode. Select menu item "24: HF1-MAX
transmitter, and adjust this parameter for 100 Watts (±5
W) of transmission power.
Select menu item "25: HF1-MID2
mitter, and confirm that the output power is 50 W
(±5W). In case the transmission power is not within the
specified tolerance, adjust this parameter for 50 W (±5
W) of transmission power.
Select menu item "26: HF1-MID1
ter, and confirm that the output power is 10 W (±1 W).
In case the power is not within the specified tolerance,
adjust this parameter for 10 W (±1 W) of transmission
power.
Select menu item "27: HF1-MIN
ter, 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.
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 re-
spectively.
Tune the transceiver to the 50 MHz band in the CW
mode. Select menu item "36: 50M-MAX
transmitter, and adjust this parameter for 100 W (±5
W) of transmission power.
Select menu item "37: 50M-MID2
mitter, 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.
Select menu item "38: 50M-MID1
mitter, and confirm that the output power is 20 W (±
2W). In case the power is not within the specified tol-
erance, adjust this parameter for 20 W (±2 W) of trans-
mission power.
Select menu item "39: 50M-MIN
ter, 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.
Tune the transceiver to the 144 MHz band in the CW

W) of transmission power.
Select menu item "41: VHF-MID
ter, and confirm that the output power is 20 W (±2 W).
In case the transmission power is not within the speci-
fied tolerance, adjust this parameter for 20 W (±2 W)
of transmission power.
