band or bands appear in the main and sub channel
displays. Transmission is possible only on the
main channel, but you can select both channels to
receive different frequencies on the same band, as
well as on different bands, simultaneously. Along
with the separate volume and squelch controls and
BUSYfTX
LEDs, each channel display has its own
memory box above an<;l to the left of the frequency,
and its own bargraph meter for signal strength or
power output indication.
Normally, the selector knob and key functions
affect only the main channel. However, by press-
ing

ing) next to the sub channel, you can cause the
controls to act on the sub channel instead. After

Frequency Selection Modes
VFOMode
This mode is for tuning or scanning the band
when looking for a channel on which to operate,
when you don't have a specific frequency in mind.
In this mode, the selector knob and arrow keys
each tune the band in the selected step size, or 1- or
10-MHz increments, and the scanning function
tunes in the selected step size. The FT-530 has two
independent VFOs (A and B), for the main channel,
and two more for the sub channel. You toggle
between the A and B VFOs by pressing
@
when
receiving. The currently selected VFO is indicated
by an "A" or "b" in the corresponding memory
box above and to the left of the channel frequency.
Memory Mode
This mode is mainly for operating on specific
channels known in advance (and stored in the
memories). For example, after storing the frequen-
cies of your local repeaters into memory channels,
you can confine operation to those channels by
selecting the memory mode. In this mode, the
DIAL
knob, arrow keys and scanning function select se-
quentially from stored memories. The FT-530 has

but only the unlocking sequence affects operation.

41 memories per band, each of which can store
repeater shift direction, CTCSS settings and sepa-
rate receive and transmit frequencies.
Each memory has a Memory Tune mode, in
which you can tune just like the VFO mode, and
store the resulting retuned memory into the same
or another memory. This and other special mem-
ory mode functions are described later, but you
will want to keep these terms in mind.
You can tell at a glance which frequency selec-
tion mode is active by looking in the shaded mem-
ory box at the upper left corner of the display. If the
box is empty (and a small "A" or "b" appears
below the box), you are in the VFO mode. If you
