Transmission - Yaesu VX-3R Operating Manual

O
PERATION
Once you have set up an appropriate frequency inside one of the 144 MHz or 430 MHz
Amateur bands on which the VX-3R can transmit, you're ready to go on the air! 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 left-hand corner of
the speaker grille) in a normal voice level. The TX/BUSY
indicator 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 indi-
cated on the bar graph at the bottom of the
LCD. Full-scale deflection confirms "High
Power" operation, while deflection of two
bars indicates "Low Power" operation. Ad-
ditionally, the "
the "Low Power" setting.
4. If you're just talking to friends in the immediate area, you'll
get much longer battery life by switching to Low Power
operation. To do this, press the [ TXPO ] key so that the
" " icon appears at the bottom of the display. And don't
forget: always have an antenna connected when you trans-
mit.
Transmission is possible only on the 144 MHz and 430 MHz bands.
1) The VX-3R is smart! You can set up Low power on 144 MHz band, while
leaving 430 MHz on High power, and the radio will remember the different
settings on both bands. And when you store memories, you can store High
and Low power settings separately in each memory, so you don't waste battery power
when using very close-in repeaters!
2) When you are operating on the Low power setting, you can press the [F/W] key,
before you press the PTT switch, to cause the VX-3R to transmit (temporarily) on High
power. After one transmission, the power level will revert to the previously-selected (Low
power) setting.
