INDICATOR FUNCTIONS

1.MODULATION METER. Indicates the percent modulation (AM only).

NOTE

The SWR/SWR CAL/MOD switch must be in the

MOD position to read modulation.

2.SWR METER. Measures the ratio of standing wave voltage of the antenna system. Used to properly adjust the length of the antenna, and to monitor the quality of the coaxial cable and all RF electrical connections. If there is any degradation whatsoever in any of the above, due to humdidity, salt spray, vibration or corrosion, the SWR meter reading will rise, therby indicating that a problem exists.

To calibrate, switch to the CAL position. Transmit by pressing the mic switch (AM mode), and adjust the SWR/CAL control to the CAL mark on the meter. Then switch to SWR position for the SWR measurement.

3.S/RF METER. Indicates relative output power and incoming signal strength.

4.CHANNEL INDICATOR. The selected channel appears on the LCD left of the channel selector knob.

5.RECEIVE INDICATOR (RX). Appears in LCD.

6.TRANSMIT INDICATOR (TX). Appears in LCD.

7.MODE INDICATOR (USB/LSB/AM). Mode appears in LCD when set by mode selector.

8.ANTENNA WARNING INDICATOR. Appears on the lower left corner of the LCD if there is a serious degradation of the antenna system SWR due to humidity, salt spray, vibration or corrosion.
