MF5 (MULTI-FUNCTION 5 SWITCH)

 

➥ Activates and selects fast, mid-range

AGC

or slow AGC time constant when

MID

 

pushed. (p. 5-11)

•In FM mode, only “FAST” is available.

➥Enters the AGC set mode when pushed and held for 1 sec. (p. 5-11)

AGC time constant can be set between

0.1 to 8.0 sec. (depends on mode), or

turned OFF. When AGC is “OFF,” the S-meter does not function.

✔What is the AGC?

The AGC controls receiver gain to produce a constant audio output level, even when the received signal strength varies dramatically. Select “FAST” for tuning and then select “MID” or “SLOW” depending on the receiving condition.

MF6 (MULTI-FUNCTION 6 SWITCH)

➥ Turns the speech compressor ON and OFF in SSB mode. (p. 6-5)

➥Switches the narrow, middle or wide compression when pushed and held for 1 sec.

✔What is the speech compressor?

The speech compressor compresses the transmitter audio input to increase the average audio output level, to increase talk power. This function is effective for long-distance communication or when propagation conditions are poor.

 

➥ Turns the 1⁄4-speed tuning function ON

1/4

and OFF in SSB data, CW, RTTY and

ON

 

PSK modes. (p. 3-6)

•1⁄4 function sets dial rotation to 1⁄4 of nor- mal speed for fine tuning.

 

➥ Switches between the tone encoder,

#4LCD FUNCTION SWITCHES [F-1]–[F-7]

Push to select the function indicated in the LCD display above these switches.

• Functions vary depending on the operating condition.

#5TRANSMIT INDICATOR [TX]

Lights red while transmitting.

#6RECEIVE INDICATOR [RX]

Lights green while receiving a signal and when the squelch is open.

#7LCD FUNCTION DISPLAY (p. 1-14)

Shows the operating frequency, function switch menus, spectrum scope screen, memory list screen, set mode settings, etc.

#8SPLIT OPERATION INDICATOR [SPLIT]

Lights during split frequency operation.

#9LOCK INDICATOR [LOCK] (p. 5-17)

Lights when the dial lock function is activated.

$0TRANSMIT FREQUENCY CHECK SWITCH [XFC] (p. 6-6)

Monitors the transmit frequency (including ∂TX frequency offset) when pushed and held during split frequency operation.

•While pushing this switch, the transmit frequency can be changed with the main dial, keypad, memo pad or

∫/ √ switches.

•When the split lock function is turned ON, pushing [XFC] cancels the dial lock function. (p. 6-7)

$1MEMORY UP/DOWN SWITCHES ∫ / √

(p. 8-2)

Push to select the desired memory channel.

•Memory channels can be selected both in VFO and memory modes.

$2KEYPAD

➥Pushing a key selects the operating band. (p. 3-4)

• GENE • selects the general coverage band.

➥Pushing the same key 2 or 3 times calls up other stacked frequencies in the band. (p. 3-4)

•Icom’s triple band stacking register memorizes 3 fre- quencies in each band.

➥After pushing F-INPENT , enters a frequency or

memory channel. Pushing F-INPENTor ∫ /

√is necessary to end the entry. (pgs. 3-5,

8-2)

• e.g. to enter 14.195 MHz, push
