HX300 Alignment
The HX300 has been carefully aligned at the factory for the specified performance across
the marine 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, a division of 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 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.

Alignment Preparation & Precautions
A dummy load and inline wattmeter must be connected to the main antenna jack in all
procedures that call for transmission. 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, 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 68 °F
and 86 °F (20 °C and 30 °C). When the transceiver is brought into the shop from hot or cold
air it should be allowed some time for thermal equalization with the environment before
alignment. If 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 procedure are based on 0 dBµ = 0.5 µV
(closed circuit).

Set the channel to CH16 and then press the [PWR] switch while press and holding the
[PRESET] keys.
Adjustment of PLL frequency
Connect the frequency counter to the antenna jack.
Press the [SCAN/DW] key till “RE” is displayed.
Press [▲] or [▼] keys while pressing the [PTT] key to set the frequency to
156.80000MHz ± 100Hz.
Press [VOL/SQL] key to fix the alignment data.
Adjustment of TX High Power
Connect the wattmeter and 50-ohm dummy load to the antenna jack.
Press the [SCAN/DW] key till “HI” is displayed.
Press [▲] or [▼] keys while pressing the [PTT] key to set the power to 4.5 ± 0.1W.
Press [VOL/SQL] key to fix the alignment data.
