Memory Features
5
The 32 memories in the FT-890, labelled 01
through 30, PI and P2, each store a pair of fre-
quencies and modes, plus wide/narrow IF selec-
tions (for CW and AM modes), clarifier on/off
and offset settings, plus split frequency status.
When you recall a memory, one set of these op-
erating parameters is displayed, and the other
set is hidden. For brevity, we will refer to the
displayed set of parameters as the
front half
of the
memory, and the hidden set as the
rear half.
The
front and rear halves can be toggled by the
AIB
button, just as you can toggle the A/B VFOs
when operating on a VFO (although the display
gives no indication of which half is which, as it
does with the VFOs). Like VFO operation, you
can operate split with the two halGes, receiving
on the front and transmitting on the rear; and
you can freely tune and change the mode or
clarifier settings of whichever half is displayed
while receiving. You can also copy a pair of set-
tings from one memory to another. In fact, you
can do nearly anything with the two halves of a
memory that you can with the A/B VFOs, except
for a few differences in tuning steps, scanning
(only the front can be scanned) and the special P1
and P2 memories, described later.
Memory Storage
Storing a memory while operating on either
VFO copies the contents of both VFOs (A and B)
into the current memory number (displayed in
small numbers at the right). Just press and hold
the
VFO-M
button for
'h second. We'll begin
with a simple example of storing only the cur-
rently displayed frequency into the front half of
a memory (the non-displayed VFO is also stored
in the rear half, but we can ignore it for now).
Example: to store 14.25 MHz from a VFO into
memory 10.
0 First press
VFOIM,
if necessary, so that either
"VFO-A"
or
"VFO-B"
appears at the left. Select
the desired mode, then tune the display to the
desired frequency
(
14.250.00) using the
HAMIGEN
and
DOWNILIP
buttons to change
bands and tune in 100-kHz steps, and then the
tuning knob as needed.
0 Next press the yellow-labelled
VFO M
button
momentarily so that "M
CK"
appears blinking
above the frequency display, and within 3 sec-
onds, press the
DOWN
or
UP
button until "
10"
(the memory number to store) appears in
small digits at the far right. If nothing was
stored there before, the frequency display will
be blank.
0 Now hold the
VFOe M
button for '&second.
Two beeps sound to confirm the memory was
stored.
Although we ignored it, keep in mind that
when we stored the displayed VFO, the hidden
one was also stored in the rear half of the same
memory. You could have pressed the
A/B
button
after setting up the first VFO and then set up the
other before storing them. Both are always writ-
ten to memory, overwriting whatever may have
been stored there previously. In addition, the
clarifier on/off state and offset for both VFOs are
also stored in the memory (whether or not the
clarifier is activated).
Checking Memo
y
Con
tents
Before storing or recalling a memory, you will
usually want to check its contents. If you are
operating on a VFO, you can of course just press
VFOIM
to recall the last-used memory, but this
has disadvantages: any current operation is in-
terrupted as your frequency changes, the an-
tenna tuner retunes (if installed), and you'll have
to press
VFOIM
again to get back to the VFO.
Also, this will not work if you are operating on a
retuned memory: you will loose any changed
settings entirely! So, the FT-890 offers a way to
display the (front) contents of memories without
affecting current VFO (or retuned memory) op-
eration, and requiring only one key press. We
call it
memory
checking, and you already did it in
the preceding example.
You activate memory checking by momentar-
ily pressing either the
VFOc M
or the
M-VFO
button. As you saw above,
"M
CK"
blinks near the
top right of the display as the frequency and
mode indicators change to show the contents of
the last-selected memory. If you touch nothing
else, the display reverts to your current operat-
ing parameters automatically after 3 seconds. By
pressing the front panel
DOWN
or
LIP
button be-
fore the 3 seconds expires, you can select for
display the front half of each of the 32 memories.
Pressing these buttons restarts the 3-second
timer, so as long as you are changing channels,
memory checking mode persists.
While checking memories, the memory num-
ber shows at the right end of the display (instead
of the 10-Hz frequency digit, if you have set that
up). Also, when you select a vacant memory, the
mode indicators and frequency display go blank
(except the decimals).
