The
FT-991
contains ninety-nine regular memories, labeled “
01
” through “
99
”, nine special programmed band edge
memory pairs, labeled “
P-1L
/
P-1U
” through “
P-9L
/
P-9U
”, and five QMB (Quick Memory Bank) memories. Each
memory stores various settings, in addition to the VFO-A frequency and mode (See below). By default, the 99 regular
memories are contained in one group; however, they can be arranged in up to six separate groups, if desired.
quick point:
The
FT-991
memory channels store the following

TheQuickMemoryBankconsistsofvememoriesindependentfromtheregularandPMSmemories.TheQMBmem-
ories can quickly store operating parameters for later recall.
QMB Channel Storage
1. Tune to the desired frequency on VFO-A.
2. Press and hold the
RCL/STO
button for one second.
The “beep” will confirm that the VFO-A contents
have been written to the currently available QMB
memory.
Repeated one second presses of the
RCL/STO
but-
ton will write the VFO-A contents to successive QMB
memories.
OnceallveQMBmemorieshavedataonthem,previ-
ousdatawillbeover-writtenonarst-in,rst-outbasis.
QMB Channel Recall
1. Press the
RCL/STO
button briefly. The current
QMB channel data will be shown on the frequency
display area. The “
QMB
” icon will also appear and
the Memory Mode indicators in the LED indicators
area will illuminate.
2. Repeated brief presses of the
RCL/STO
button will
toggle through the QMB channels.
3. Press the
V/M
button to return to the VFO or Memo-
ry mode.

Advice:
Rotating the Main Tuning Dial knob, or changing the
operating mode, will place the transceiver in the “Mem-
ory Tune” mode, which is a temporary “pseudo-VFO”
method of tuning off of a stored memory channel. If you
do not over-write the contents of the current memory
channel, the original contents will not be disturbed by
the initiation of Memory Tune operation.
