displayed on the LCD to confirm selection. You will note that a calculated step-adjust value is displayed
on the bottom of the LCD as "ADJ+ 7.50" representing a positive offset of +7.5 kHz with a step size of 15

requirement the required offset is actually 5 kHz.

it displays 7.50 kHz - yes, it works! Access the step menu to review the figures, they will
show a step size of 15 kHz and step-adjust of 5 kHz... clever!
Example 3: This example shows just how bizarre the bandplan can be. Assume that you wish to tune
from 145.210 MHz in 14 kHz steps (i.e. 145.210, 145.224, 145.238, 145.252, 145.266 etc). When
manually tuning, the AR8200 would normally correct the frequency display to read 145.236 then step
upward in 14 kHz steps. Tuning back downward will skip 145.210 MHz (the starting point) as the original
frequency was not divisible by step size.
