E-TONE CONTROL :

 This control is used to control the echo effects. 

 

6.

 

RF POWER CONTROL : 

This control enables adjustment of RF power output 

continuously up to the rated output power.  

 

7.

 

BAND SELECTOR :

 This band selector allow the user to select the desired band. 

 

8.

 

MODE CONTROL :

 This control allows you to select one of the following 

operating modes : CW/FM/AM/USB/LSB. 

 

9.

 

FINE/COARSE CONTROL :

 Allows variation of the receive operating 

frequency above or below the assigned frequency. Although this control is intended 
primarily to tune in SSB/CW signals, it may be used to optimize AM/FM signals as 
described in the Operating Procedure paragraphs. Coarse operates both TX/RX but 
Fine only in RX. 

 

10.

 

CHANNEL SELECTOR :

 This control is used to select a desired transmit and 

receive channel. 

 

11.

 

MICROPHONE JACK : 

 Used to connect microphone for voice source. 

 

12.

 

FRONT PANEL METER :

 The Front Panel Meter allows the user to monitor 

signal strength, RF output power and SWR level. 

 

13.

 

TX/RX LED :

 The red LED indicates the unit is in the transmit mode. The green 

LED indicates the unit is in the receive mode.

 

 

14.

 

FREQUENCY COUNTER : 

This frequency counter indicates the selected 

channel frequency digitally.

 

 

15.

 

TALKBACK SWITCH : 

This switch is used to monitor the sound feedback 

effects.

 

 

16.

 

HI/LOW SWITCH : 

This switch select HI or LOW band of operation. 

 

17.

 

NB/ANL/OFF SWITCH :

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

RF Noise Blanker (NB) and the Automatic Noise Limiter (ANL) in the audio 
circuits are activated. The Noise Blanker is very effective in eliminating repetitive 
impulse noise such as ignition interference. 

 

18.

 

S-RF/SWR/ SWITCH :

 In the S-RF position, the meter swings proportionally to  

the strength of the received signal. When transmitting, the meter indicates relative 
RF output power. When in the SWR position, the standing wave ratio is measured. 

19.

 

ROGER BEEP : 

When this switch is placed in the ROGER BEEP position, the 

radio automatically transmits an audio tone at the end of your transmission. This 
indicates the end of your transmission so that people who are having trouble 
hearing you will know that you are done speaking. As a courtesy to others, use the 
Roger Beep only when necessary. 

 

20.

 

+10KHz SWITCH : 

In the +10KHz position, the transmit and receive frequency is 

shifted 10 KHz up. 

 

21.

 

CHANNEL DISPLAY :

 The channel display indicates the current selected 

channel.
