OPERATION

TRANSMISSION

Once you have set up an appropriate frequency inside the 430 MHz Amateur band on which the VX-177can 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 “LOW” icon will 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 430 MHz amateur band.

“LOW” POWER

“MID” POWER

Changing the Transmitter Power Level

To change the power level:

“HIGH” POWER

￿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 “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.

1)The VX-177 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-177 to transmit (temporarily) on High power. After one transmission, the power level will revert to the previously-selected (“Low” or “Medium” power) setting.
