Test Setup
Set up the test equipment as shown below for transceiver alignment, apply 6 V
DC power to the transceiver. Refer to the drawings for Alignment Points.
Internal System Alignment Routine
This uses a programmed routine in the transceiver which simplifies many
previously complex discrete component settings and adjustments with digitally-
controlled settings via front panel buttons and LCD indications.
To begin, set the transceiver to the center of the 50MHz, 144MHz, 220MHz and
430MHz bands. Next, select the 430MHz band, then turn the transceiver off.
Now, press and hold the [BAND], [H/L] and [V/M] button together while
powering the radio on again. The display will show the first setting.
Note that the first few settings are not adjustable and are left as set from the
factory.
In the alignment process, each adjustment is selected by rotating the DIAL.
Alignment is performed by:
○
Pressing the [V/M] button;
○
Injecting a signal of the required frequency and level; then
○
Pressing the [V/M] button after a level setting or adjustment is made. This
second pressing of the [V/M] button store the entry.
To exit the alignment routine, press the [HM/RV] button. After performing the
system alignment in its entirety, individual settings can be returned to and adjust
should the need arise
In the section to follow, typical default values (as set at the factory) are shown in
brackets (e.g. [119]), to serve as a general guideline. As each transceiver is
individually optimized at the factory, the precise settings for the transceiver on
your bench may be slightly different.
