Once you have set up an appropriate frequency inside one of the dual amateur bands on
which the
VX-8GR can transmit (144 MHz or 430 MHz), you’re ready to transmit. These
are the most basic steps; more advanced aspects of transmitter operation will be discussed
later.
1. To transmit, press the PTT switch, and speak into the
front panel microphone (located in the upper right-hand
corner of the speaker grille) in a normal voice level.
The LED of the “
A
” or “
B
” which is designated the
“Main” band will glow red during transmission.
2. To return to the receive mode, release the
PTT
switch.
3. During transmission, the relative power level will be
indicated on the LCD. Additionally, the “
L1
”, “
L2
”, “
L3
”,
or “ HI ” icon will appear at the left side of the PO meter,
corresponding with the “Power” Level setting.
1) If you’re just talking to friends in the immediate
area, you’ll get much longer battery life by switching to Low Power opera-
tion. To do this, press the
f
key, then press the
d
key so that the “Low
Power” icon appears at the bottom of the display. And don’t forget: always have an
antenna connected when you transmit.
2) Transmission is not possible on the “Sub” band, nor on any frequencies other than
the 144 MHz and 430 MHz bands on the “Main” band.
3) Never transmit without having an antenna connected.

You can select between a total of four transmitter power levels on your VX-8GR . The
exact power output will vary somewhat, depending on the voltage supplied to the trans-
ceiver. With the standard
FNB-101LI Battery Pack and external DC source, the power
output levels available are: “
L1
”, “
L2
”, “
L3
”, or “
HI
”
To change the power level:
1.
The default setting for the power output is “High;” in
this configuration, the display shows the “
HI
” icon.
Pressing the
f
key, followed by the
d
key, causes
the power level “ L1 ”, “ L2 ”, or “ L3 ” to appear.
2. Press the
f
key, followed by the
d
key (repeat-
edly, if necessary) to make the “ HI ” icon appear and
restore “High Power” operation.
