PERATION
If the optional Dual Receive Unit ( RXU-9000 ) is installed, Digital Automatic Notch Filter operation is available on both
the VFO-A and VFO-B. Operation is identical on either VFO.
As a reminder, there is no difference in the fundamental performance of the two VFOs. Please see page 62 for details.
VFO-A Band DNF Operation
Press the VFO-A D.NOTCH switch (# ) to engage the
Digital Notch filter. The LED imbedded in the switch will
glow Red, to confirm that the DNF circuit is engaged.
To cancel DNF operation, press the VFO-A D.NOTCH
switch (#
) once more. The imbedded LED will go out,
confirming that the Digital Notch Filter is no longer in
operation.
Sub (VFO-B) Band DNF Operation
1. Pressing the SUB RX switch (# ) will engage
Dual Receive operation.
When the imbedded LED glows green, this is your
confirmation that Dual Receive is in operation.
2. Press the VFO-B DNF switch (# ) to engage the
Digital Notch filter. The LED imbedded in the switch
will glow Umber, to confirm that the DNF circuit is
engaged.
To cancel DNF operation, press the VFO-B DNF switch
(#
) once more. The imbedded LED will go out, con-
firming that the Digital Notch Filter is no longer in opera-
tion.
