The Clarifier (RIT) allows you to set an offset of up to ±9.99 kHz of the receive frequency
relative to your transmit frequency. To achieve wider offset, you may use the “split”
operating mode, described later.
1.
Press the [
CLAR
] switch momentarily to activate the Clarifier function.
2.
Turn the
SEL
knob, which allows the receiver frequency to be varied over a range of
9.99 kHz.
3.
When offsets the receiving frequency higher than transmit frequency, appear the “
"
”
icon at the right of the frequency display. Similarly, when offsets the receiving
frequency lower than transmit frequency, appear the “
#
” icon at the right of the
frequency display.
4.
When the receiving frequency equal transmit frequency (Clarifier offset is zero) while
the Clarifier is activated, appear the “
–
” icon at the right of the frequency display.
5.
To turn the Clarifier off, again press the [
CLAR
] switch momentarily.
6.
To reset the Clarifier offset to zero, turn the Clarifier off, then turn the
DIAL
by any
amount. The Clarifier will reset to zero after the first “step” of the
DIAL
.
IF SHIFT

IF SHIFT
The receiver’s IF SHIFT feature is an effective interference-reduction tool, which allows you
to shift the passband response higher or lower without changing the pitch of the incoming
signal.
1.
Press the [
CLAR
] switch for one second to activate the IF SHIFT feature. A “
$
”, “
#
,” or
“
$
” icon will appears at the right of the frequency display to inform the IF SHIFT’s
current position.
2.
Rotate the
SEL
knob, as needed, to reduce or eliminate interference.
3.
To turn the IF SHIFT feature off, again press the [
CLAR
] switch for one second. The
last setting of the IF SHIFT control will be retained until you change it again.

The receiver recovery time constant may be modified to match your operating needs.
1.
Press the [

2.
Press the [

where “AGCauto” represents “AGCfast” on CW and DIG(AFSK), and “AGCslow” on the
voice modes.

2.
Press the [

The IPO feature bypasses the receiver RF preamplifier, thereby eliminating the preamp’s
gain. This feature is not available on the 144 MHz and 430 MHz.
1.
Press the [
F
] key momentarily, then rotate the
SEL
knob, as needed, until Operating
Function Row [
IPO
,
ATT
,
NAR
] on the display.
2.
Press the [
