bank, select scan channel, pass frequency etc).
The “< - -” legend then reverses to point back to
where the frequency was displayed. If the legend
“- - - - - - - - - -” is displayed then the current memory
channel is confirmed as currently being empty. If data is
already present in the memory location, the previously
stored frequency will be displayed as a warning that the
stored data is about to be over-written.
The microprocessor will automatically select the youngest
free memory location. You may change the memory
location at this time by rotating the
MAIN DIAL
(which selects
all 1000 memory channels in sequence) or keying in a
three digit number comprising of BANK+CHANNEL (x.xx).
The
SUB DIAL
selects the next EMPTY memory location.
Note: The
keys are used for selecting
alpha-numeric text in the context of memory operation
and should not be used at this point.
Remember, if you take too long entering data (about 90
seconds) the display will revert to its original VFO condition.
Assuming that you wish to store 88.3 MHz in memory
channel 100 irrespective of what may already be stored
there, press
to select the bank 1 then press
to select the first channel. Finally type
to accept
the memory location.
The TEXT menu will now be displayed. The flashing
legend “
TXT
TXT
TXT
TXT
TXT
” is displayed to the right of centre of the
LCD, the memory location is displayed in static form on
the right of the LCD. Even if data is being over-written,
any previously stored text will be erased and a blank field
provided for TEXT addition.
Note: If you do not wish to add an alpha-numeric text
comment press
to complete the process and
commit new data to memory. It is possible to add text at
a later time.
To aid text entry, a decimal “.” is displayed to the right of
the text entry point (initially close to the left of the LCD).
The
SUB DIAL
is used to make selection of text in the form
of upper case letters, numbers and symbols. The
and
keys move the text entry point to the right and
left respectively. If a mistake is made during entry, use
the
key to move back to the required position and
simply over-write it.
You will note that each time the entry point is moved and
text selected, the next letter offered is not “

continues from the character, number or symbol last used.
A few short cuts are provided via the numeric keypad:

If you are happy with the alphanumeric description press
, the display will return to VFO mode.
At any time you may abort memory input by pressing the
key, the display will return to VFO mode.
To toggle the FREQUENCY / TEXT display while in
memory recall, scan and search modes press
followed by a brief press of the
key.
7-2 Memory recall - Recalling receive data
from memory
Once receive frequency and mode data have been stored
into a memory location, its retrieval is quick and simple.
Let’s assume that you wish to retrieve the frequency of
88.3 MHz which has been programmed into to memory

Press
to place the receiver into memory recall
mode. The bank legend appears on the top right of the
LCD with bank and channel numbers underneath to
confirm operation, note that the word “SCAN” is not
present at this time.
The AR5000 will monitor whatever memory channel first
appears when you enter memory recall mode.
The AR5000 displays memory location (bank & channel
number), mode, I.F. bandwidth, attenuator status,
