Introduction
This manual provides technical information necessary
for servicing the FT-2000 HF/50 MHz Transceiver.
Servicing this equipment requires expertise in handling
surface-mount chip components. Attempts by non-qualified persons to service this equipment may result in permanent damage not covered by the warranty, and may
be illegal in some countries.
Two PCB layout diagrams are provided for each doublesided circuit board in the Transceiver. Each side of is referred to by the type of the majority of components installed on that side (“leaded” or “chip-only”). In most
cases one side has only chip components, and the other
has either a mixture of both chip and leaded components
(trimmers, coils, electrolytic capacitors, ICs, etc.), or leaded components only.
While we believe the technical information in this manual to be correct, VERTEX STANDARD assumes no liability for damage that may occur as a result of typographical or other errors that may be present. Your cooperation in pointing out any inconsistencies in the technical
information would be appreciated.

Alignment
Introduction and Precautions
The following procedures cover adjustments that are
not normally required once the transceiver has left
the factory. However, If a problem occurs during
normal operation due to component failure; realignment may be required after the faulty components
have been replaced.
We recommend that authorized Vertex Standard
Technicians, who are experienced with the circuitry
and fully equipped to repair and align our products,
perform repairs. If a fault is suspected, contact the
selling dealer for instructions regarding repair. Authorized Vertex Standard Technicians have the latest information to align all circuits and make complete performance checks to ensure compliance with
factory specifications after repairs.
Those who do undertake any of the following alignments are cautioned and proceed at their own risk.
Problems caused by unauthorized attempts at realignment are not covered by the warranty policy.
Vertex Standard must reserve the right to change
circuits and alignment procedures in the interest of
improved performance, without notifying owners.
Under no circumstances should any alignment be
attempted unless the normal functions and operation of the transceiver are clearly understood, the
cause of the malfunction has been clearly identified
and all faulty components replaced. The need for
realignment should be determined to be absolutely
necessary.
The following test equipment (and a thorough familiarity with its correct use) is necessary for correct
realignment. Most steps do not require all of the
equipment listed. The interactions of some adjustments may require that more complex adjustments
be performed in a sequence. Do not attempt to perform only a single step unless it is clearly isolated
electrically from all other steps. Have all test equipment ready before beginning, and follow all of the
steps in a section in the order they are presented.
Required Test Equipment
RF Signal Generator
AF Signal Generator
Spectrum Analyzer good to at least 1 GHz.
Frequency Counter
SINAD Meter
RF Millivoltmeter
Digital DC Voltmeter (high-Z, 1 M-Ohm/V)
DC Voltmeter
DC Ammeter (20 A)
Ohmmeter
DMU-2000 Data Management Unit
50-Ohm Dummy Load (100 watts)
100-Ohm Dummy Load (100 watts)
150-Ohm Dummy Load (100 watts)
In-Line Wattmeter (100 watts, 50-Ohm)
Linear Detector
RF Coupler
4-Ohm AF Dummy Load (3 watts)
Alignment Preparation & Precautions
A 50-ohm RF Dummy load and in-line wattmeter
must be connected to the “ANT 1” jack in all procedures that call for transmission, except where specified otherwise. Correct alignment is not possible with
an antenna.
After completing one step, read the following step
to determine whether the same test equipment will
be required. If not, remove the unneeded test equipment before proceeding. (except the dummy load
and wattmeter).
Correct alignment requires that the ambient temperature be maintained constant between 68 °F ~ 86 °F
(20 °C ~ 30 °C). When the transceiver is brought into
the shop from a hot or cold enviroment, it should be
allowed time to come to room temperature before
alignment. Also, the test equipment must be thoroughly warmed up before beginning.
Whenever possible, alignments should be made with
oscillator shields and circuit boards firmly affixed in
place. Also, the test equipment must be thoroughly
warmed up before beginning.
Note: Signal levels in dB referred to in this proce-
dure are based on 0 dBμ = 0.5 μV (closed circuit).
ALIGNMENT-1
Alignment
Analog Meter Adjustment
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.
Rotate the Main Tuning Dial knob to select the
alignment parameter “A01 FSC.”
Rotate the [SUB(VFO-B)] knob so that the Main
S-meter deflects to full scale.
Press and hold in the [MENU] button for 2 sec-
onds to save the new setting and exit from the
alignment mode.
SHIFT/WIDTH Knob
Zero (Center) Adjustment
Set the SHIFT/WIDTH knobs to the 12-o’clock
position.
Set the operating mode to “USB.”
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.
Rotate the Main Tuning Dial knob to select the
alignment parameter “A02 SFt.”
Rotate the [SUB(VFO-B)] knob so that the IF
SHIFT frequency is set to “±0.00” on the external
display. The center point (±0.00) is broad (17
points). Therefore, set the [SUB(VFO-B)] knob to
the center of this broad range.
Rotate the Main Tuning Dial knob to select the
alignment parameter “A03 udt.”
Rotate the [SUB(VFO-B)] knob so that the IF
bandwidth is set to “2.4 kHz” on the external display. The IF bandwidth (2.4 kHz) is broad (24
points). Therefore, set the [SUB(VFO-B)] knob to
the center of this broad range.
Press and hold in the [MENU] button for 2 sec-
onds to save the new setting and exit from the
alignment mode.
VDD Meter Adjustment
Connect the DC voltmeter to pin 6 of J5402 on
the PA-A Unit.
Switch the external display to “SWR Monitor”
page.
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.
Rotate the Main Tuning Dial knob to select the
alignment parameter “A04 vdd.”
Press the [ENT] key, then rotate the [SUB(VFO-
B)] knob so that the VDD meter (Main S-meter)
reading is the same as that on the DC voltmeter.
Rotate the [VRF] knob so that the VDD meter (on
the external display) reading is same as that on
the DC voltmeter.
Press and hold in the [MENU] button for 2 sec-
onds to save the new setting and exit from the
alignment mode.
ALIGNMENT-2
Alignment
2nd Local Oscillator (Main) Adjustment
Disconnect the coaxial cable from J4004 on the
LOCAL Unit, then connect the Frequency counter
to J4004.
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.
Rotate the Main Tuning Dial knob to select the
alignment parameter “A15 FrE.”
Rotate the [SUB(VFO-B)] knob so that the Fre-
quency counter reading is “69.000 MHz.”
Press and hold in the [MENU] button for 2 sec-
onds to save the new setting and exit from the
alignment mode.
Disconnect the Frequency counter from J4004,
then connect the RF millivoltmeter to J4004.
Adjust T4003 and T4004 on the LOCAL Unit for
maximum deflection on the RF millivoltmeter
(more than –5 dBm).
Disconnect the RF millivoltmeter from J4004, then
re-connect the coaxial cable to J4004.
