VX-7R OPERATING MANUAL18

TRANSMISSION

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. Addition-

ally, the “L1,” “L2,” or “L3” icon will appear at the bottom of the display, correspond-

ing 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 key so that the “L” icon appears at the

bottom of 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 trans-

ceiver. 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, followed by the

key, causes the power level “L1,” “L2,” or “L3” to appear.

2. Press the key, followed by the key (repeatedly, if necessary) to make the

“Low Power” icon disappear and restore High Power operation.

)

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 differ-

ent 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!
