Indicators

Analog Meter

The meter needle swings proportionally to the strength of the incoming signal 

or RF output power in receive or transmit modes.

When used to tune the antenna or monitor the quality of the coaxial cable and 

RF electrical connections, the needle swings proportionally to the ratio of standing 

wave ratio and RF output. If there is any degradation in these, due to humidity, 

salt, spray, vibration or corrosion, the SWR meter reading will rise, thereby 

indicating that a problem exists.

RX / TX Indicator

This indicator glows green when in receive mode and red when in transmit mode.

- -

Antenna Warning Indicator

This indicator glows red whenever the standing wave ratio is greater than 3 to 1.

Microphone

The receive and transmit modes are controlled by the Press-To-Talk (PTT) switch 

on the microphone. Press the switch to transmit, release it to receive. When transmitting,

hold the microphone two inches from the mouth and speak clearly in a normal voice. 

To substitute for the supplied low-impedance (500 ohm) dynamic microphone, 

see the alternate microphones and installation section on page 17.

Operating to Receive

To begin operating your radio:

1.

Be sure the power source, microphone and antenna are properly connected.

2.

Turn the unit on by turning the volume knob clockwise and set the volume for a

comfortable listening level.

3.

Set the PA / AM / FM switch to the desired AM or FM.

4.

Set the RF gain control fully clockwise for maximum RF gain.

5.

Listen to the background noise from the speaker, then turn the squelch ring slowly

clockwise until the noise just disappears (no signal should be present). Leave the

control at this setting. The squelch is now properly adjusted. The receiver will remain

quiet until a signal is actually received. Do not advance the control too far, or some 

of the weaker signals will not be heard.

6.

Select the desired frequency with the band and frequency selector knobs.

7.

Adjust other controls as desired.

Operating to Transmit

To transmit a signal:

1.

Select the desired frequency for transmission if different from the one 

chosen to receive.

2.

Set the microphone gain knob fully clockwise.

3.

If the frequency is clear, depress the Press-To-Talk switch on the 

microphone and speak in a normal voice.
