Note that while receiving, one or more bargraph segments may appear along the bottom of
the display, indicating signal strength on the receiving frequency. This indication is not
affected by the squelch setting, so even squelched signals may have some indication. If you
notice more than one or two bargraph segments appearing while the squelch is still closed,
try reducing the squelch control setting (if you want to hear weak signals).
The Monitor switch on the USA versions (just above the PTT switch) allows you to check
for channel activity beneath the squelch level and to adjust the volume without having to
adjust the squelch: just press the Monitor switch and the squelch will open.

Press the [
VFO
(
PRI
)] button, if necessary, to select the VFO mode. The
VX-150
has two
vfos, labelled “
A
” and “
B
” either of which can be used for all of the procedures described
in this manual. You can change vfos with the [
VFO
(
PRI
)] button at any time.
You have several ways to tune the
VX-150
: in selectable channel steps or 1 MHz steps
with the [
s
] / [
t
] keys or
DIAL
knob, and direct keypad frequency entry.
Use the
DIAL
knob to tune the displayed VFO frequency at the current channel step rate.
You can also press the [
s
] / [
t
] keys momentarily to do this, but if you press an [
s
] or
[
t
] key for more than 1/2-second scanning will start. This is described later, so for now,
just press an [
s
] / [
t
] key again to stop (if you have to).
To change the MHz range of the VFO, you can press the [
F/W
] key followed by an [
s
] or
[
t
] key (or turn the
DIAL
knob). Note the beeps when using the [
s
] / [
t
] keys: when
moving up, and when moving down. When done press [
F/W
] again, or just wait five sec-
onds.
You can also enter a frequency directly just by keying in the 1 MHz and the kHz digits. If
you are using 5 or 10 kHz steps enter five digits. Otherwise just four digits will do. Partial
entries can be cancelled with the [
VFO
(
PRI
)] key.
