VX-3200V Alignment
Introduction
The VX-3200V is carefully aligned at the factory for the specified performance across the
frequency range specified for each version. Realignment should therefore not be necessary
except in the event of a component failure, or altering version type. All component
replacement and service should be performed only by an authorized Vertex Standard
representative,or the warranty policy may be void.
The following procedures cover the sometimes critical and tedious adjustments that are not
normally required once the transceiver has left the factory. However, if damage occurs and
some parts subsequently are placed, realignment may be required. If a sudden problem
occurs during normal operation, it is likely due to component failure; realignment should not
be done until after the faulty component has been replaced.
We recommend that servicing be performed only by authorized Vertex Standard service
technicians who are experienced with the circuitry and fully equipped for repair and
alignment. Therefore, if a fault is suspected, contact the dealer from whom the transceiver
was purchased for instructions regarding repair. Authorized Vertex Standard service
technicians realign all circuits and make complete performance checks to ensure compliance
with factory specifications after replacing any faulty components.
Those who do undertake any of the following alignments are cautioned to proceed at their
own risk. Problems caused by unauthorized attempts at realignment are not covered by the
warranty policy. Also, Vertex Standard reserves 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 function and
operation of the transceiver are clearly understood, the cause of the malfunction has been
clearly pinpointed and any faulty components replaced, and realignment determined to be
absolutely necessary.
The following test equipment (and thorough familiarity with its correct use) is necessary for
complete realignment. Correction of problems caused by misalignment resulting from use of
improper test equipment is not covered under the warranty policy. While most steps do not
require all of the equipment listed, the interactions of some adjustments may require that
more complex adjustments be performed afterwards.
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 presented.

Alignment Preparation & Precautions
A 50-ΩRF Dummy Load and in-line wattmeter must be connected to the main antenna 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 test equipment (except dummy load and
wattmeter, in connected) before proceeding.
Correct alignment requires that the ambient temperature be the same as that of the
transceiver and test equipment, and that this temperature be held constant between 20 and
30°C (68 ∼86 °F). When the transceiver is brought into the shop from hot or cold air, it should
be allowed time to come to room temperature before alignment.
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:

Note: Signal levels in dB referred to in the alignment procedure are based on
0dBµEMF = 0.5µV.
Setup the test equipment as shown for transceiver alignment,apply 13.8V DC power to the
transceiver. Refer to the drawings above for Alignment Points.
