Step Offset - AOR AR8000 Operating Manual

1.08 kHz (which are not divisible by 50 Hz), the last digit will not be accepted so
may be corrected simply by typing [5].
In fact should you wish, even frequencies listed in the standard STEP list may
be entered directly through the numeric keypad once in the "STEP SET" menu.
For example, to program a step size of 25 kHz using the numeric keypad:
Press [FUNC] [2] [2] [5] [ENT]
The display will return to VFO mode with the new step size programmed.
6-10 STEP OFFSET facility
As reported in section 6-9 of this manual (changing step size), the bandplan
may not always be adhered to or for some reason you may wish to tune or
search using a different format.
Examples of this are European cell phones which are allocated in 25 kHz
channel steps but the lower band edge does not start on a round MHz such as
917 MHz but 12.5 kHz higher at 917.0125 MHz (in other words it is offset by
+12.5 kHz). Also European VHF utility services sometimes operate using a
12.5 kHz channel step but the lower band edge is offset by +6.25 kHz.
To ensure that the AR8000 can follow most of these unusual bandplans, the
active frequency (in VFO mode) or lower band edge (in search mode) may be
offset in a positive (+) direction by half the current step size.
For example, to tune from 71 MHz in 12.5 kHz steps offset by 6.25 kHz carry
out the following key sequence:
[7] [1] [ENT] to select 71.000 MHz
[FUNC] [2] to enter the "STEP SET" menu
Press [PASS] to select STEP OFFSET the legend "+" appears to the right
of the word "STEP"
Rotate the [DIAL] on the top cabinet until the "12.50" kHz step
size is displayed
Press [ENT] to select the data input
The receiver will return to VFO mode and the
frequency displayed will be updated to read 71.0062
MHz (the actual frequency is 71.006250 MHz but the
LCD does not show the 50 Hz digits). This means
that the displayed frequency has been offset by +6.25
kHz.
Rotating the [DIAL] clockwise will increase the frequency by 12.5 kHz so that
the new frequency will be displayed as 71.0187 MHz (the actual frequency
