ALIGNMENT-3
Alignment
2nd Local Oscillator (Main) Adjustment
ˆ
Disconnect the coaxial cable from J4004 on the
LOCAL Unit, then connect the Frequency counter
to J4004.
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
Rotate the Main Tuning Dial knob to select the
alignment parameter “A15 FrE.”
ˆ
Rotate the [SUB(VFO-B)] knob so that the Fre-
quency counter reading is “69.000 MHz.”
ˆ
Press and hold in the [MENU] button for 2 sec-
onds to save the new setting and exit from the
alignment mode.
ˆ
Disconnect the Frequency counter from J4004,
then connect the RF millivoltmeter to J4004.
ˆ
Adjust T4003 and T4004 on the LOCAL Unit for
maximum deflection on the RF millivoltmeter
(more than –5 dBm).
ˆ
Disconnect the RF millivoltmeter from J4004, then
re-connect the coaxial cable to J4004.
PLL (Main) Adjustment
ˆ
Connect the Digital DC voltmeter (high-Z) to
TP4003 on the LOCAL Unit.
ˆ
Disconnect the coaxial cable from J4002 on the
LOCAL Unit, then connect the RF millivoltmeter
to J4002.
ˆ
Referring to the table below, adjust the listed com-
ponents for the required voltage, or confirm that
the correct voltage is present on each frequency
listed.
ˆ
Disconnect the RF millivoltmeter from J4002, then
re-connect the coaxial cable to J4002.
PLL (Sub) Adjustment
ˆ
Connect the Digital DC voltmeter (high-Z) to
TP4004 on the LOCAL Unit.
ˆ
Disconnect the coaxial cable from J4007 on the
LOCAL Unit, then connect the RF millivoltmeter
to J4007.
ˆ
Referring to the table below, adjust the listed com-
ponents for the required voltage, or confirm that
the correct voltage is present on each frequency
listed.
ˆ
Disconnect the RF millivoltmeter from J4007, then
