Introduction
This manual provides technical information necessary for servicing the FT-950 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
double-sided 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 “chiponly”). 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.

Important Note
This transceiver was assembled using Pb (lead) free solder, based on the RoHS specification.
Only lead-free solder (Alloy Composition: Sn-3.0Ag-0.5Cu) should be used for repairs performed on this apparatus. The solder
stated above utilizes the alloy composition required for compliance with the lead-free specification, and any solder with the
above alloy composition may be used.

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
Electronic Load
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)
In-Line Wattmeter (100 watts, 50-Ohm)
Linear Detector
RF Coupler
4-Ohm AF Dummy Load (3 watts)
1/4-inch 3-contant Plug
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 environment, 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.
Important Notice
Do not adjust the alignment menus that are not
mentioned in this manual.
