Section 3-8
Should you wish to change the default tuning step size
The third main text line of the LCD will display the current default
size (perhaps "25.00" kHz). If the reverse LCD legend "AUT"
displayed in the upper right corner of the LCD, this indicates that
AUTO MODE / STEP is currently selected.
The bottom line of the LCD displays the legend "STEP SET" to
indicate that the AR8200 is inviting you to change the step size.
Use the main dial or
The list is as follows: 0.05 kHz (50 Hz), 0.1 kHz (100 Hz), 0.2 kHz
(200 Hz), 0.5 kHz (500 Hz), 1.00 kHz, 2.00 kHz, 5.00 kHz, 6.25
kHz, 8.33 kHz, 9.00 kHz, 10.00 kHz, 12.50 kHz, 20 kHz, 25.00 kHz,
30 kHz, 50 kHz, 100.00 kHz.
To accept the displayed tuning step size
the LCD will revert to its previous display.
Note: The frequency step of 8.33 kHz has been included
for compliance with the new VHF airband allocation, it has been
correctly implemented as eight-and-one-third kHz so that no
compound error arises (i.e. the last digits display 33, 66, 00).
The tuning step size may also be programmed in multiples of 50 Hz (via the keypad) so that unusual step
sizes other than stated are possible. The acceptable step size range is 0.05 kHz (50 Hz) to 999.95 kHz
in 50 Hz steps.
When the desired step size has been entered,
to accept the new step size. If you attempt to input an invalid step
size, the error beep will sound (presuming that the beep facility is
enabled) and the incorrect input will be ignored.
* Active frequency must be divisible by step size *
There is just one small point to bare in mind, the active frequency
must be divisible by the step size... in 99% of cases they will be.
However, should you start experimenting with different step sizes
you may notice the active frequency change automatically to
the nearest multiple of step size as the AR8200 calculates
automatically for you, there is no need to carry a calculator!
For example, select 118.000 MHz then select a 9 kHz step size:
The receive frequency will currently be displayed as 118.000 MHz but once the main dial has been used, the
displayed frequency will be corrected to 117.9990 or 118.0080 MHz (depending upon the direction of tuning)
both of which are the closest multiple of 9 kHz to 118 MHz.
