However, the STEP-ADJUST facility is used to address this situation.

With the above in mind, 58.445 MHz with 15 kHz steps in mind, while in VFO mode, key in the start

frequency of 58.445 MHz

Access the STEP menu using the key sequence . 15 kHz is not a

standard size provided by rotating the main dial so key in the required 15 kHz step size.

(do NOT press enter!). to access the

STEP-ADJUST menu. Accessing this menu will activate the step-adjust facility, the “ADJ” legend will be

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

kHz… the AR8200 often assumes that you require a half step. However when looking at the

requirement the required offset is actually 5 kHz. ò to move the cursor to the step-adjust

(bottom) line. Use the main dial to select 5.00 kHz (or key in 5 kHz ).

to accept the displayed data. The display will return to VFO mode with 58.445 MHz

displayed. The main dial will now correctly follow the required bandplan.

Manual intervention is not always required

Note: The AR8200 is not all that dumb really, in the above example, as soon as you

pressed the key the CPU realised that a half step was not appropriate so would

have selected an offset of 5 kHz automatically! Try it and see, just while

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.
