Transmission; Changing The Transmitter Power Level - Yaesu VX-7R Operating Manual

O
PERATION
Once you have set up an appropriate frequency inside one of the three (or four) Amateur
bands on which the VX-7R 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 upper right-hand corner of the speaker grille) in a normal voice level. The
"STROBE" 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. Full power
(5 Watts) is indicated by eight arrows below the frequency display. The three "Low
Power" levels (L1, L2, and L3) are indicated by two, four, or six arrows, respectively.
Additionally, the "L1," "L2," or "L3" icon will appear at the bottom of the display,
corresponding with the "Low Power" Level setting.
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
key, then press the
display. And don't forget: always have an antenna connected when you transmit.
Transmission is not possible on any operating bands other than the 50 MHz, 144 MHz, 222
MHz, and 430 MHz bands.

Changing the Transmitter Power Level

You can select between a total of four transmitter power levels on your VX-7R. The exact
power output will vary somewhat, depending on the voltage supplied to the transceiver.
With the standard FNB-80LI Battery
Pack and external DC source, the power
output levels available are:
To change the power level:
1. The default setting for the power output is "High;" in this configuration, the LCD
shows no indication of the power output level. Pressing the
key, causes the power level "L1," "L2," or "L3" to appear. .
2. Press the key, followed by the
"Low Power" icon disappear and restore High Power operation.
1 ) The VX-7R is smart! You can set up Low power on one band (like UHF),
while leaving VHF on High power, and the radio will remember the different
settings on each band. 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!
