HX600S Alignment
The HX600S has been carefully aligned at the factory for the specified performance
across the land mobile band.
Realignment should therefore not be necessary except in the event of a component
failure.
All component replacement and service should be performed only by an authorized
STANDARD HORIZON representative, or the warranty policy may be voided.
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 are replaced, 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 STANDARD HORIZON
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 STANDARD HORIZON 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, STANDARD HORIZON 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 function
and operation of the transceiver are clearly understood, the cause of the malfunction has
been clearly pinpointed and any faulty components replaced, and the need for 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.
Required Test Equipment
ο Radio Tester with calibrated output level at 200 MHz
ο In-line Wattmeter with 5% accuracy at 200 MHz
ο 50 Ω, 10 W RF Dummy Load
ο Regulated DC Power Supply adjustable from 3 to 15 VDC, 2A
ο Frequency Counter: ±0.2 ppm accuracy at 200 MHz
ο AF Signal Generator
ο AC Voltmeter
ο DC Voltmeter: high impedance
ο VHF Sampling Coupler
Alignment Preparation & Precautions
A 50 ΩRF 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 next step to see if the
same test equipment is required. If not, remove the test equipment (except dummy load
and wattmeter, if 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 ~

30 °C (68 ~ 86 °F). When the transceiver is brought into the shop from hot or cold air, it
should be allowed some 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.
Set up the test equipment as shown below for transceiver alignment, apply 7.2 VDC power
to the transceiver.
Notes: signal levels in dB referred to in alignment are based on 0 dBµ = 0.5 µV
(closed circuit).
