Transmission - Yaesu VX-170 Operating Manual

Once you have set up an appropriate frequency inside the 144 MHz Amateur band on
which the VX-170 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.
To transmit, press the PTT switch, and speak into the
front panel microphone (located in the lower left-hand
corner of the speaker grille) in a normal voice level.
The TX/BUSY indicator will glow red during trans-
mission.
To return to the receive mode, release the PTT switch.
During transmission, the relative power level will be
indicated 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. Five bars indicate
"Medium Power" operation. Additionally, the "
appear at the bottom of the display while operating on the "Low
Power" and "Medium Power" settings.
1) If you're just talking to friends in the immediate area,
you'll get much longer battery life by switching to Low
Power operation, described in the next chapter. And don't
forget: always have an antenna connected when you transmit.
2) Transmission is possible only on the 144 MHz amateur band.
Changing the Transmitter Power Level
To change the power level:
Press the [ F ] key, then press the [ 3 ( LOW )] key. The
LCD shows the current power output level.
Rotate the DIAL knob to select the desired power out-
put level. Available selections are "
LOW
(2 W), and "
When you have made your choice, press the PTT switch
to save the new setting and return to normal operation.
1) The VX-170 is smart! When you store memories, you can store the power
output 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" or "Medium" power setting, you can press the
[F] key, then press the PTT switch, to cause the VX-170 to transmit (temporarily) on
High power. After one transmission, the power level will revert to the previously-se-
lected ("Low" or "Medium" power) setting.
