6-12 Entering a frequency via the keypad
Where exact frequencies are known, you may wish to enter a frequency
directly through the keypad.  The numeric keypad is located on the front panel
underneath and to the right of the LCD.  The keypad is laid out in a logical
manner and is split into numeric and command areas.
The numeric keys are used for entering a frequency with the decimal key [.]
acting as a separator.  It is possible to enter frequencies as MHz, kHz or by
metre band.
Entry as MHz:
For example,  to select 14.10000 MHz follow the key sequence:
[1] [4] [.] [1] [MHz] (MHz frequency entry)
You will note that the trailing zeros are not required as the AR3030 completes
the entry at the time the [MHz] key is pressed.
Entry as kHz:
For example,  to select 4722 kHz (4.722 MHz) follow the key sequence:
[4] [7] [2] [2] [kHz] (kHz frequency
       entry)
Entry as mtr:
Should you wish to start listening to a
Broadcast or Amateur band but not a
specific frequency,  the [mtr] key
provides immediate access with minimal
key presses.  The information will
update as you recall [mtr] band and tune
the receiver.
At default the following [mtr] key defaults
apply:
Attenuator is always OFF
VFO is always [A]
Filter is always [NORM]
AGC is always [SLOW].
With the frequency, mode and step size
defaults:
Correcting frequency input errors via
the keypad
Should you make a mistake when
entering a frequency via the keypad there are two methods of correction.

Back Space delete
The [ENT/BS] key acts as a “BS” Back Space just like a computer keyboard
deleting data input from the right hand side.
For example,  if you wish to enter 3.750 MHz but had keyed [3] [.] [7] [5] [8]
the last digit being “8” in place of “0”,  before pressing [MHz] press the [ENT/
BS] key.  The last digit on the right hand side will be deleted.  You can then
press the correct key [0] and complete the sequence with [MHz].
Should you press [ENT/BS] twice during the sequence,  then the first two digits
on the right hand side would be deleted and so on.
[MEMO] - abort frequency input
Should you decide to abort the frequency input during programming,  press the
[MEMO] key once to abort.  The display will return to the frequency prior to
input and the sequence aborted.
6-13 Memory mode - [MEMO] - [M.in] - [PASS] - [ENT/BS]
There are 100 memory channels (00 to 99) which can store frequency, mode,
AGC, attenuator, bandwidth, AF filter (tone), BFO status and lockout status.
The memories can be used to store shortwave or VHF frequencies if the VHF
converter option has been fitted.
Program scan allows only a selected block of channels to be scanned while
lockout causes certain channels to be skipped.  Pause and delay scan add to
flexibility.
Data may be easily entered into memory or from memory to VFO for tuning.
There is a massive EEPROM store for all memory channels and VFO data
so that no memory backup battery is required.  The memories may be
over-written time and time again.
Note: Memory channels 1 to 9 must be entered using a zero prefix.
i.e. memory channel 2 is “02” and channel 3 is “03” etc.
Memory select - [MEMO] key
In VFO mode the LCD display will not show any legend relating to the memory
operations such as memory channel number, SCAN and PASS.
To select memory mode press the [MEMO] key.  The legend “MEMO” will
appear on the LCD to confirm selection. 
						

							AR3030 operating manual
33
Presuming data has been stored,  in memory mode press [0][1] to select
memory channel 1, [0][2] for memory channel 2, etc.
Alternatively you may rotate the main rotary tuning control to select memory
channel.  If no data has been stored then “empty” channels will be “skipped”
when turning the main rotary tuning control or when selected via the keypad.
While the legend “MEMO” is displayed along with a channel number,  the
AR3030 will be actually receive the displayed frequency.
Return to VFO:
To return to VFO mode simply press the [VFO] key.
Transfer memory to VFO:
To transfer the current memory data to VFO press [MEMO] while the “MEMO”
legend is displayed on the LCD.
6-14 Memory write - [M.in] key
While tuning in VFO mode,  you may wish to store an interesting or regularly
used frequency into memory so that it may be called upon quickly and
conveniently.
To store the current VFO data into memory (which includes frequency, mode,
AGC, ATT, TONE, BW, BFO status, tuning step) the [M.in] and [ENT/BS]
keys are used.
Automatic:
Press the [M.in] key and the AR3030 will automatically select the first lowest
number empty memory channel (unless they are all in use in which case
channel [00] is always selected).  The memory channel number will appear on
the lower left hand side of the LCD and will flash to indicate memory write
mode.
Press the [ENT/BS] key to complete the sequence.
As the AR3030 automatically increments to the next available memory
channel,  it is easy to keep the memory channel allocation sequential and tidy
without having to remember which channels have already been used.
Manual:
It is possible to store VFO data into any of the 100 memory channels and over-
write current data if required. 
						

							AR3030 operating manual
34
Let’s assume that you have 14.25000 MHz USB displayed in VFO mode and
you wish to write into memory channel number 25 which has not been
previously used.
Press [M.in] followed by the channel number desired memory channel number
[2] [5],  ignore any automatically displayed channel number before 25 was
keyed.  The chosen channel number will flash to indicate memory write mode.
To complete the sequence press the [ENT/BS] key, a beep sounds to confirm
correct entry.
Note:  If the memory channel already had data present then the previously
stored data would “cause the whole LCD to flash twice” and a low-level
beep sounded to draw your attention that you will over-write data.
You must wait for the two flashes to execute before completing the
sequence with the [ENT/BS] key.  A high pitched beep confirms correct entry
and completion of the memory input sequence.
Of course if you decide not to over-write the data which has been displayed
simply select another memory channel using the keypad.
To abort memory input press [MEMO].
6-15 Deleting memory contents
Although you may over-write memory channels time and time again, there will
be occasions when you may wish to delete a particular memory channel or
whole bank of channels.  This is especially true if you are reorganising the
memory contents or planning to use the program scan facility.
Deleting a single memory channel
While in VFO mode press the [M.in] key and the LCD will show the first
available memory channel flashing.
Now press the [PASS] key which changes the LCD to show both “dEL-CH” and
“—” legends. 
						

							AR3030 operating manual
35
Enter the two digit memory channel number which you wish to erase  such as
[2] [3].  The legend “—” will be replaced by memory channel number which
you have selected “23” and will flash.
Complete the delete sequence by pressing the [ENT/BS] key.  A beep confirms
correct data entry and the completion of the delete sequence.  The receiver will
automatically revert to VFO mode.
To abort memory delete press the [M.in] key.
Deleting a block of memory channels
Let us assume that you wish to delete memory channels 30 to 45 inclusive.
While in VFO mode press the [M.in] key and the LCD will show the first
available memory channel flashing.
Now press the [PASS] key which changes the LCD to show both “dEL-CH” and
“—” legends.
Enter the lower two digit memory channel number which you wish to erase i.e.
[3] [0].  The legend “—” will be replaced by memory channel number which
you have selected “30” and will flash.
Now press the [.] key to inform the receiver that you are conducting a multiple
memory channel delete rather than deleting a single channel. 
						

							AR3030 operating manual
36
Enter the higher two digit memory channel number which you wish to erase i.e.
[4] [5].  The legend “—” will be replaced by memory channel limits “30” and
“45” which will flash alternatively.
Complete the delete sequence by pressing the [ENT/BS] key.  A beep confirms
correct data entry and the completion of the delete sequence.  The receiver will
automatically revert to VFO mode.
The memory channels 30 to 45 inclusive will have been deleted.
To abort memory delete press the [M.in] key.
Deleting the contents of 
all memory channels simultaneously
This is accomplished as shown above in the example of deleting a block of
memory channels.  In this instance the lower limit for delete is the first memory
channel and the higher limit is the highest memory channel - all of them.
In VFO mode,  press [M.in] [PASS] [0][0][.][9][9][ENT/BS]
The display will return to VFO mode automatically after approximately six
seconds.
6-16 Memory Channel Scan
It is sometimes useful to instruct the AR3030 to automatically monitor a
number of memory channels especially when activity is low.  This process is
known as “scanning”.
It is possible to scan any mixture of bands simultaneously  LW, MW, HF and
VHF at the same time (VHF reception provided an optional VHFconvertor is
fitted).
Before memory channel scan can operate you must first store data into
at least two channels,  of course you can store data in to all 100 should
you choose. 
						

							AR3030 operating manual
37
The receiver must first be placed into VFO mode.  If in doubt press the
[VFO] key and check that the “MEMO” legend is not shown on the LCD.
Press [SCAN] to start memory channel scan from the memory channel last
used.  Both the “MEMO” and “SCAN” legends will appear on the LCD to
confirm operation.  All memory channels containing data will be scanned but
empty channels will be skipped.
To stop the scanning process press [SCAN] again.  The receiver will continue
to receive on the channel where scan has been stopped but will return to VFO
mode copying the data automatically.
To resume scanning once again simply press [SCAN].
6-17 Program Memory Channel Scan
It is possible to instruct the AR3030 to scan a group of memory channels
rather than all channels which contain data.  This is a convenient method of
scanning a few memory channels without needing to delete temporarily
unwanted memory channels.
The following example assumes data is stored in about the first twenty memory
channels,  you wish to scan only channels 5 to 12 inclusive.
Ensure the receiver is in VFO mode,  if in doubt press the [VFO] key and
ensure that “MEMO” is 
not displayed.
Press [SCAN] to start scanning.  Press the [ATT] key to inform the receiver
that you wish to input programme scan data.  The LCD will show “SCAn-CH”
to confirm program scan data input mode has been selected.  The current
bottom and top scan limits will then flash in sequence.
Enter the lower two digit memory channel number,  in this example [0][5].
Now press the [.] key to inform the receiver that you are about to enter the
higher memory channel number for programme memory scan.  The channel
legend “05” will be replaced by “--” when the [.] key has been pressed. 
						

							AR3030 operating manual
38
Enter the higher two digit memory channel number for programme memory
scan,  in this example [1][2].  The legend “—” will be replaced by memory
channel limits “05” and “12” which will flash alternately.
Complete the sequence by pressing the [ENT/BS] key.  A beep confirms
correct data entry and the AR3030 will commence programme memory scan
between the specified limits.
To stop programme memory scan press [SCAN].
6-18 Pass channel operation
While scanning, there will be occasions when you will want to skip over one
memory channel or a number of channels.  Under these circumstances
program memory scan may not be ideal as the channels you wish to skip may
not be consecutive.   This is where memory channel “PASS” is used.
Where the PASS facility is used to cause memory scan to skip the specified
channel,  the memory channel is referred to as being “LOCKED OUT”.
For example,  if you wish to lock out memory channel 8, press [MEMO] while
in VFO mode followed by [0][8].  Press [PASS] to complete the sequence.
The “08”, “MEMO” and “PASS” legends will appear on the LCD to confirm
operation.
While in MEMO mode,  all locked out memory channels are identified on the
LCD with a “PASS” legend.  You may use the main tuning control in memory
mode to scroll through the memory channels.
6-19 Pause time programming in scan mode
The AR3030 does not immediately scan from channel to channel rapidly.  This
is to allow the receiver’s AGC and other circuitry to react to the changing noise
and signal levels between different frequencies.  If the scan speed is too quick,
then weaker signals would be completely missed.
The pause time for memory scan may be programmed between the limits of 1 
						

							AR3030 operating manual
39
and 10 seconds.  The factory default is 5 seconds.
For example,  should you wish to program pause time to 3 seconds carry out
the following sequence.
While in VFO mode press [SCAN] to start memory channel scan.
Press [MEMO] to inform the AR3030 that you wish to reprogramme scan
pause time.  The LCD will show “PAUSE 5” and the figure 5 flashes to indicate
the present value.
Press [3] to alter the pause time from 5 to 3 seconds. Figure 3 replaces the
previous figure and flashes to confirm input.
Press [ENT/BS] to complete the sequence,  a beep will confirm complete data
input.
6-20 Delay time programming in scan mode (VHF only)
The scanning system is handled slightly differently on the VHF bands when an
optional VHF converter is fitted.
During VHF scanning, the position of squelch (OPEN/CLOSED) determines
when the set stops scanning and for how long.
Basically the receiver will scan the memory channels until the squelch opens,
it will then remain on the busy channel until the squelch closes again.  It is then
assumed that the channel has become clear so the set is ready to start
scanning again.
However rather than immediately scanning, the receiver will “delay” for a short
time to allow for a reply from an airband control tower etc.
The programmable delay range is from 0.5 seconds to 3 seconds in 0.1
second increments.  The factory default is 1.5 seconds.
To alter the delay time (VHF only), ensure firstly that you are in VFO mode.
Press [SCAN] to start memory scan (you may wish to use programme
memory scan to select only VHF memory channels). 
						

							AR3030 operating manual
40
Press [AGC] to inform the AR3030 that you wish to reprogramme scan delay.
The LCD will show “dELAy 1.5” and the figures “1.5” flash on the LCD to
confirm selection.
Let’s assume you wish to change the delay time from 1.5 to 0.8 seconds.
Press [0][.][8]
Press [ENT/BS] to complete the sequence which is confirmed by a beep. The
scan delay time will now be 0.8 seconds.
(7) Computer control (RS232C)
The AR3030 is capable of remote control via the 9 pin female D-type rear
connector (section 5-31) using a simple RS232 cable without the need for an
interface.
7-1 Connection
Connection to an IBM PC 25 pin D-type serial port requires the following
connections:
      IBM-PC 25 pin                            AR3030 9 pin
        1 , 7           Frame & signal groud        5
