6. SWR 

LED:

 This LED lights red when your SWR is higher than about 3:1. This is 

not an exact indicator of 3:1 SWR, but it is an indication that you should check 
your SWR reading. 

7. CHANNEL 

SELECTOR:

 This control is used to select the desired transmit and 

receive channel. 

 
8.  FRONT PANEL METER:

 The front panel meter allows the user to monitor 

incoming signal strength, RF output power, SWR level and AM modulation level. 

 
9. RF 

GAIN 

CONTROL:

 This control is used to reduce the gain of the RF (receive) 

amplifier under strong signal conditions. 

 
10. DIMMER CONTROL:

 This knob controls the level of brightness for the meter 

lamp and channel display. 

 
11. SWR/MOD/PWR SWITCH: 

This switch controls the function of the meter 

during the transmit mode. In the “SWR” position, the meter indicates the Standing 
Wave Ratio (SWR) of your antenna. There are no adjustments because the SWR 
circuit in this radio calibrates itself automatically. When the switch is in the 
“MOD” position, the green scale on the meter indicates your percentage of 
modulation in the AM mode only. They are most accurate when testing at 
maximum power output.  When this switch is in “PWR” position, the meter 
indicates your power output. 

 
12. NB-ANL/CB/PA SWITCH:

 When the switch is in the NB/ANL position, the 

Noise Blanker (NB) and Automatic Noise Limiter (ANL) circuits are activated. 
The Noise Blanker is very effective in eliminating repetitive impulse noise such 
as ignition interference. In the CB position, the PA function is disabled and the 
radio will transmit and receive on the speaker that is connected. In the PA position, 
the radio acts as public address amplifier. Your voice will come out of the speaker 
that is plugged into the PA. SP. jack on the rear panel. The radio does not operate 
when you are in the PA mode. 

 
13. TALKBACK SWITCH:

 This feature is used to monitor your own voice. For 

example, you could use this feature to compare different microphones. HI is high 
volume. LO is low volume. The Talkback circuit is off when the switch is in the 
OFF position. 

14. RX/TX LED:

 This LED is green during receive and red during transmit. 

 
15. CHANNEL  DISPLAY:

 The channel display indicates the current selected 

channel.

REAR PANEL 

1. ANTENNA:

 This jack accepts a 50-ohm coaxial cable with a PL-259 type plug. 

2. DC 

POWER:

 This jack accepts the 13.8V DC power cable with built-in fuse. 

The power cord provided with the radio has a black and red wire. The black goes 
to negative and red goes to positive. 

3. PA 

SP:

 This jack is for PA operation. Before operating, you must first connect a 

PA speaker (8 ohms, 4W) to this jack. 

4. EXT. 

SP:

 This jack accepts a 4 to 8 ohm, 5-watt external speaker. When the 

external speaker is connected to this jack, the built-in speaker will be disabled. 

5. F.C.:

 This jack is used to connect the optional Galaxy FC347 six-digit frequency 

counter. All connections, including DC power, are provided to the FC347 through 
this jack.
