Changing Frequency Using The Main Dial - AOR AR8600 Operating Manual

Note: When tuning, reception may occasionally be momentarily
interrupted while tuning and the "S" squelch legend will flash as tuning
progresses, some noise may accompany tuning, this is normal.
Fast tuning
The and keys may be used to tune the receiver at a rate TEN TIMES
FASTER than the selected step size. This means that when a step size
of 25 kHz is selected, tuning will be in 250 kHz steps, this provides a
convenient method to quickly tune up and down frequency bands.
Note: Be aware that when auto-mode is selected and a tuning
step change has automatically taken place, one PUSH up or down
may take several pushes to arrive back to the starting place again.

deactivate as a toggle), the tuning rate for the

While in VFO mode, the active VFO frequency may be 'tuned' in a similar way to a domestic receiver or
other specialist receivers using the rotary tuning main dial which is mounted on the right hand side of
the front panel. You may rotate the control between your fingers or place your thumb near the edge and
rotate using a circular motion... use whatever is most comfortable.
This method of frequency selection is the most traditional approach to locating signals particularly on
the short wave and medium wave bands. It provides an easy method to locate new or previously
unknown frequencies or to check activity within certain frequency bands such as amateur or short wave
broadcast. The rotary tuning main dial provides the very best 'user interface' with the AR8600 especially
for USB, LSB and CW listening.
Rotating the main dial 'clockwise' increases frequency while
rotation 'anti-clockwise' decreases receive frequency.
The speed at which the main dial tunes the receiver depends upon the STEP SIZE which is default to
AUTO. Examples of tuning step include: 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. 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.
While the "FUNC" legend is displayed (achieved by a
deactivate as a toggle), the tuning rate for the main dial is TEN TIMES FASTER than the selected step
size. This means that when a step size of 10 kHz is selected, tuning will be in 100 kHz steps, this
provides a convenient method to quickly tune up and down frequency bands.
