RX CLAR Switch
Pressing this button activates the RX Clarifier, to al-
low offsetting the Main (VFO-A) receiving frequency
temporarily. Press this button once more to return the
Main receiver to the frequency shown on the main fre-
quency display field; the Clarifier offset will still be
present, though, in case you want to use it again. To
cancel the Clarifier offset, press the [ CLEAR ] button.
TX CLAR Switch
Pressing this button activates the TX Clarifier, to al-
low offsetting the Main (VFO-A) transmit frequency
temporarily.
Press this button once more to return the transmitter to
the Main (VFO-A) frequency shown on the main fre-
quency display field; the Clarifier offset will still be

CLEAR Switch
Pressing this button clears out any frequency offset you
have programmed into the Clarifier register (thereby
setting the offset to "Zero").
CLAR Knob
This knob tunes the Clarifier offset frequency up to
9.99 kHz.
VRF Knob
This knob tunes the passband of the VRF (Variable RF
Filter) preselector circuit for maximum receiver sensi-
tivity (and out-of-band interference rejection).
A :
DVICE
The relative position of the VRF passband can be
observed on the Tuning Offset Indicator of the dis-
play via Menu item "010 diSP BAR SEL
When the optional RF μTuning Kit is connected,
this knob allows adjustment of the center frequency
of the μ-Tuning filter passband (which is much
narrower than that of the VRF).

any other RF filter in the Amateur industry, yielding
outstanding protection from high RF levels not far re-
moved from the current operating frequency.
NOTCH Switch
This button turns the Main band (VFO-A) receiver's
IF Notch Filter on and off.
When the IF Notch Filter is activated, the peak posi-
tion of the IF Notch Filter is depicted graphically in

NOTCH Knob
This knob adjusts the center frequency of the Main
band (VFO-A) receiver's IF Notch Filter. The Notch
Filter is engaged via the [ NOTCH ] button.
Initially, the approximate center frequency of the IF
Notch Filter is adjusted by the outer [ COARSE ] knob;
then, fine tuning of the center frequency is adjusted by
the inner [ FINE ] knob.
