Tuning The Receiver Using The Rotary Controls; Entering A Frequency Via The Numeric Keypad - AOR AR5000 Operating Manual

VFO-E Accept the frequency from the scan mode
If a frequency is keyed in to VFO-E and the
held for more than one second the search process will
commence from the displayed frequency.
If is pressed while in SCAN MODE, the active
frequency will be transferred to VFO-E, the AR5000 will
switch to VFO-E automatically where you may monitor
and tune from the selected frequency.
Note: If you press the VFO key for one second
or longer, SEARCH will be activated.

6-3 Tuning the receiver using the rotary controls

The receiver may be tuned using the rotary tuning controls
( and ) which are used to select receive
frequency and in memory mode for selection of memory
channel etc.
A tuning knob is by far the most traditional approach to
tuning on short wave, the
feel and the best method of user interface especially when
listening on the SSB, FAX and CW modes. The
is indented so tunes in a number of clicks and is best suited
for channelised tuning on the VHF/UHF bands.
It is possible to tune the receiver through it's entire range
from 10 kHz to 2600 MHz. Rotating the
clockwise increases the displayed frequency
(and tunes the receiver upward), rotating the controls
anti-clockwise decreases the displayed frequency (and
tunes the receiver downward).
The keys may also be used to increase or
decrease the receive frequency.
The AR5000 has an AUTOMODE capability where the
receive mode, frequency step and I.F. filter selection is
made automatically by the AR5000 microprocessor
following detailed bandplan information (for each world
market area). This very much simplifies and speeds up
operation, particularly in the early stages of familiarisation.
When automode is active, the legend "AUTO" is displayed
above the right hand digit (last one, Hz) of frequency
readout. If it is not displayed, press and hold the

key

key for more than one second, the "AUTO" legend will
appear on the LCD to confirm selection.

6-4 Entering a frequency via the numeric keypad

Select VFO mode and the desired VFO out of the five
available " ", " ", "
by pressing the key several times until the desired
VFO is displayed on the lower right corner of the LCD
(i.e. " ").
The AR5000 is now in a known state of operation ready
for data input.
There are two methods of frequency entry, MHz & kHz:
MHz
The key is used to enter frequencies as MHz while
in VFO mode. For example to enter a frequency of 88.300
MHz follow the key sequence
There is no need to add the trailing zeros to the right,
once the key has been used the AR5000
microprocessor will automatically add the additional trailing
digits. The display will read "88.300000 MHz"
kHz
The key is used to accept frequency input via the
numeric keypad in kHz format. For example: To key in a
frequency of 954 kHz, key
will display "
as keying 0.954MHz or .954MHz (Note: keying a decimal
before the number causes a preceding zero to be
added automatically).
The kHz method of frequency entry reduces the number
of key presses required when working with low frequencies
and simplifies operation as short wave listings are often
stated in kHz. Example: Oceanic air traffic 5616kHz or
short wave transmissions Radio Netherlands 5955kHz and
6045kHz.
Note: Frequencies below 3.0 MHz (3000 kHz) will always
be displayed as kHz regardless of the entry format. It is
usually more convenient to enter medium wave / long wave
frequencies using the kHz format.
