the VX-120/170 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 transmission.
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 indicates "Medium Power"
operation. Additionally, the "LOW" icon will appear at the bottom of the display while
operating on the "Low Power" and "Medium Power" settings.
R.F. Says: 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/W] key, then press the [3(LOW)](VX-170) or [LOW(SET/LOCK)](VX-120)
key. The LCD shows the current power output level.
Rotate the DIAL knob to select the desired power output level. Available selections are
"HIGH" (5 W), "MID" (2 W), and "LOW" (0.5 W).
When you have made your choice, press the PTT switch to save the new setting and
return to normal operation.
R.F. Says: 1) The VX-120/170 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/W]
key, when press the PTT switch, to cause the VX-120/170 to transmit (temporarily) on High
power. After one transmission, the power level will revert to the previously-selected ("Low" or
"Medium" power) setting.
Now that you're mastered the basics of VX-120/170 operation, let's learn more about some of
the really neat features.
