Microphone Gain:

211 

 Adjusts the microphone gain in the transmit and 

PA modes. This controls the gain to the extent that full talk power is 

available several inches away from the microphone.

RF Gain: 

211 

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

amplifier under strong signal conditions. For maximum receiver 

sensitivity  this  control  should  be  turn  all  the  way  to  the  right 

(clockwise).

Noise Blanker / ANL Switch: 

221 

When this switch is in the NB position 

the noise Blanker circuits are activated. The Noise Blanker is very 

effective in eliminating repetitive pulse type noise usually associated 

with ignition systems. The ANL position activates both the Noise 

Blanker and Automatic Noise Limiter (ANL) Circuitry.

Echo Volume: 

231 

Varies the volume or number of echo repetitions. To 

increase the echo volume, rotate the control clockwise.

Echo Delay: 

241 

The Echo switch turn the echo on. A big advantage to 

this is you can turn it off and then back on with the switch without the 

need to adjust your volume & delay potentiometer. To turn the echo 

off simply move the switch to the middle position.

Fin: 

251 

This is the fine control for the clarifier. Please refer to the function 

menu section for specific options related to this control. With the 

clarifier in the default mode, the fine knob would be used to fine tune 

your receiving frequency. In general this is typically on used on SSB.

COA: 

261 

This is the coarse control for the clarifier. With the clarifier in 

default mode, the coarse knob would be used in conjunction with the 

fine knob to tune in the station you communicating with. Both knobs 

increase frequency when turned clockwise and decrease when turned 

counter clockwise.

Channel Selector:

271 

 This control is used to select the desired transmit 

and receive channel.
