■ Functions for transmit

D Transmit frequency check
When “DUP” appears in the display such as for a

from the receive frequency.

In such cases, the transmit frequency should be mon-

itored before transmitting to prevent interference to
other stations.

■ Functions for receive

D Squelch function
The squelch function detects signals with voice com-
ponents and squelches (mutes) unwanted signals
such as unmodulated beat signals. This provides
quiet stand-by.
When you need to receive weak signals, the squelch
should be turned OFF.
➥ Push [F] then [2 SQL] to switch the function ON
[F] [2 SQL]
and OFF.
• See page 48 for the squelch level adjustment. • “SQL” appears when the squelch function is turned ON.

D Noise blanker
The noise blanker function reduces pulse type noise
such as that coming from engine ignitions, etc.

The noise blanker may distort reception of strong sig-

nals. In such cases, the noise blanker should be
turned OFF.
4
➥ Push [F] then [1 NB] to switch the function ON and
OFF. [F] [1 NB]
• See page 48 for the noise blanker level adjustment.
• “NB” appears when the NB function is turned ON.

D AGC OFF function

The receive gain is automatically adjusted according
to received signal strength with the AGC (Automatic
Gain Control) function to prevent distortion from
strong signals and to obtain a constant output level.

When receiving weak signals with adjacent strong

signals or noise, the AGC function may reduce the
sensitivity. In this situation, the AGC function should
[F] [5 AGC×]
be deactivated.
• “ A G C” appears when the AGC function is turned OFF.
➥ Push [F] then [5 AGC×] to switch the function ON
and OFF.

The receiver gain can be reduced with the RF gain q Push [F] then [6 RF-G] to select the RF gain set

nals while monitoring strong signals.

Usually, the AGC function reduces the RF gain ac-

cording to the receive signal strength and these weak
signals are removed. However, during no signal re-
ception, these weak signals may not be heard.

In such cases, the RF gain may be useful for setting a

minimum level at which to hear signals. w Rotate [CH] to set the desired minimum cutting
level.
• “0 (low sensitivity)” to “9 (max. sensitivity)” are available.
• S-meter shows the minimum permitted level.

4 RECEIVE AND TRANSMIT

■ Functions for receive (continued)

D Clarity control
Voice signals received from other stations may be diffi-
cult to receive. This may sometimes happen if a sta-
tion is transmitting slightly off frequency. In such cases,
you can compensate by using the clarity control.

q Push [F] then [RX CLAR] to switch the function ON

and OFF.
• “CLAR” and shifting value with direction appear.

• Adjustable between ±150 Hz in 10 Hz steps.

D Tuner through function

In the combination with IC-M802 and optional AT-140
(or AH-3), the tuner through function can be used.
By bypassing the tuner unit, the receiver gain in par-
ticular frequency band may be improved depending
on your antenna element length.

[TUNE THRU] to tuner through function ON. [TUNE THRU] [F]
• “THRU” appears instead of “TUNE” indicator.

selectable in set mode as described on p. 51.
➥ Full break-in (receiving is possible while transmitting)
➥ Semi break-in (automatic transmission with keying)

more grounding you provide for your central electronics, the
