Once you have set up an appropriate frequency inside one of the three (or four) Amateur
bands on which the VX-8R can transmit (50 MHz, 144 MHz, or 430 MHz, plus 222 MHz
on the USA version), you're ready to transmit. These are the most basic steps; more ad-
vanced 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 lower right-hand
corner of the speaker grille) in a normal voice level.
The LED of 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
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 "Sub" band and any operating bands other than the
50 MHz, 144 MHz, 222 MHz (USA version), and 430 MHz bands on the "Main" band.
