If the optional Dual Receive Unit ( RXU-9000 ) is installed, IF Width 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 58 for details.
VFO-A Band IF Width Operation
Rotate the VFO-A WIDTH knob (# ) to adjust the
bandwidth. Counter-clockwise rotation reduces the band-
width, while clockwise rotation increases the bandwidth.
Sub (VFO-B) Band IF Width 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. Rotate the VFO-B WIDTH knob (# ) to adjust
the bandwidth. Counter-clockwise rotation reduces the
bandwidth, while clockwise rotation increases the
bandwidth.
