[RF GAIN] knob: Fully clockwise
[SUB RX] button: ON
ˆ
Connect the RF Signal Generator to the “ANT 1”
jack, then set the frequency to 14.200 MHz.
ˆ
Connect the AC millivoltmeter, Frequency
Counter, and 4 Ohm dummy load to the EXT SP
jack.
ˆ
Set the Sub Band (VFO-B) frequency to 14.200
MHz in the CW mode.
ˆ
Press and hold in the [1(1.8)], [2(3.5)], and [3(7)]
keys, while turning the radio on, to enter the
alignment mode.
ˆ

ˆ
Set the RF Generator frequency so that the Fre-
quency counter reading is “1 kHz,” then adjust
the Sub [AF GAIN] knob so that the AC
millivoltmeter reading is “0 dB.”
ˆ
Set the RF Generator frequency so that the Fre-
quency counter reading is “300 Hz.”
ˆ
Rotate the [SUB(VFO-B)] knob so that the AC
millivoltmeter reading is “–6 dB (±0.2 dB).”
