AR5000 OPERATING MANUAL PAGE 13
- CONFIG
This 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
the LCD will display
954.000 kHz. This has the same effect 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.
The key sequence
activates the CONFIG
menu where the lamp On/Off, keypad beep tone status
OFF / volume, external IF output, remote baud rate, aerial
(antenna) automatic switching and internal / external
frequency reference may be configured.
- AF.SET
This key is used primarily to select receive mode.
To select AUTOMODE press and hold the
key
for more than one second, the receive mode, I.F.
bandwidth and frequency step will be selected by the
AR5000 automatically from its extensive pre-programmed
bandplan listing.
When automode is in operation, the legend “AUTO” is
displayed above the right hand digit (Hz position) of the
frequency red-out.
To over-ride the receive mode, briefly press the
key. The options are: FM, AM, LSB, USB, CW and AUTO.
WFM is supported as a product of the I.F. bandwidth
selected (i.e. 110 or 220 kHz).
The key sequence
activates the AF.SET
(audio frequency set-up) where the AUDIO LOW PASS
FILTER (3.0 kHz, 4.0 kHz, 6.0 kHz or 12 kHz), AUDIO
HIGH PASS FILTER (0.05 kHz, 0.2 kHz, 0.3 kHz or 0.4
kHz), AUDIO DE-EMPHASIS (25, 50, 75, 750 or THRU),
CW PITCH (0.4 kHz, 0.5 kHz, 0.6 kHz, 0.7 kHz, 0.8 kHz,
0.9 kHz, 1.0 kHz or 1.1 kHz) and AUDIO INPUT
(INTERNAL or EXTERNAL) may be configured.
- AGC
This key primarily selects the frequency step size for tuning
the receiver. If the legend ”AUTO” is displayed then the
step size will automatically be determined from the
automode bandplan data, as soon as another selection is
made automode is cancelled.
The standard step sizes offered for the MAIN DIAL are:
0.001 kHz (1 Hz), 0.010 kHz (10 Hz), 0.050 kHz (50 Hz),
0.100 kHz (100 Hz), 0.500 kHz (500 Hz), 1.000 kHz,
5.000kHz, 6.250 kHz, 9.000 kHz, 10.000 kHz, 12.500
kHz, 20.000 kHz, 25.000 kHz, 30.000 kHz, 50.000 kHz,
100.000 kHz and 500.000 kHz.
In addition unusual step sizes may be entered using
the numeric keypad (i.e.
for 22 kHz or
for 200 Hz).
The SUB DIAL may also be configured for: MAIN (same as
MAIN DIAL), x10 speed of MAIN DIAL, 0.1 kHz, 0.5 kHz, 1.0
kHz, 5.0 kHz, 10.0 kHz, 50.0 kHz, 100.0 kHz, 500 kHz or
1000.0 kHz (1 MHz).
AGC
The key sequence
activates the AGC
(Automatic Gain Control) menu.
In FM mode the options are AGC ON / OFF and in other
modes are OFF, FAST, MIDDLE and SLOW. When AGC
OFF has been selected, two horizontal bars are displayed
on the LCD between the kHz and MHz legends.
FM: AGC OFF
AGC ON
Other modes: AGC OFF
AGC FAST
AGC MIDDLE
AGC SLOW
Note: “
AUTAUT
AUTAUT
AUT” for AUTO AGC will be displayed toward the
top right of the LCD if AUTOMODE is in operation and
the appropriate AGC selection will be made automatically
by the AR5000.
- S.SET
This key is used to PASS (skip over) unwanted active
frequencies in search and scan mode. In search mode,
the unwanted frequencies are held in a special PASS LIST
where they may be added to, deleted or reviewed. In
scan mode the memory is locked out so is skipped.
The pass list is laid out in 20 banks for search mode (00
to 19) plus one extra for frequencies to be skipped while
in VFO mode.
Pressing the
key while in memory recall mode or
scan mode locks out the current channel so that it will be
skipped over. The “PASS” legend is displayed to the left
of the memory channel number (above the “M” legend) to
signify that the channel is selected as PASS. The
key acts as a toggle, simply press it again to remove the
PASS status.
When the key sequence is keyed while in
SCAN mode or MEMORY RECALL mode, the displayed
channel is added to the SELECT SCAN list. This is a
special temporary notepad memory bank. The legend
“
SS
SS
S” is added to the display above the channel number, to
the left of the bank number to signify that the channel is
selected for SELECT SCAN (see section 10 of this
manual).
Note: If this key is accidentally pressed, it may give the
impression that the AR5000 is not receiving certain
frequencies... so make sure you are familiar with the PASS
operations.
