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 in-
coming signal.
1. Press the
switch for one second to activate
the IF SHIFT feature. A “ ”, “ ,” or “ ” icon will
appear at the right of the frequency display to
indicate the IF SHIFT’s current position.
2. Rotate the
knob, as needed, to reduce or
eliminate the interference.
3. To turn the IF SHIFT feature off, again press the
switch for one second. The last setting of the IF SHIFT
control will be retained until you change it again.
4. If you wish to make a more permanent shift in the receiver’s IF
passband, use Menu #54 (LSB) or #55 (USB) in the “Extended
Menu”. This allows you to set up a higher or lower listening
pitch, if you prefer such as compared to the default passband
response. See page 62.
Engaging of the IF Shift feature does not disable the setting
of the Clarifier control. With the IF Shift activated, press the
switch momentarily to switch to Clarifier operation.
AGC
(
Automatic Gain Control
)
The receiver recovery time constant of the AGC system may be modified to match your
operating needs.
1. Press the key momentarily, then rotate the
knob, as needed, until Operating
Function Row 8 [NB, AGC] appears on the display.
2. Press the
(AGC) key to toggle the AGC recovery time constant among the follow-
ing selections:
“AGCauto”
“AGCfast”
“AGCslow”
“AGCoff”
“AGCauto” ……
where “AGCauto” represents “AGCfast” on CW and DIG(AFSK), and “AGCslow” on the
voice modes.
If “AGCoff” selected, the S-meter (which monitors AGC voltage) will cease to func-
tion.
