FLEX-6000 Signature Series – Maestro User Guide

mode, the reception bandpass is shown on the Panadapter as a light blue band while the transmit

bandpass is shown as a light red band. If the transmitter is not assigned to the Slice, a vertical

dotted red line marks the transmit frequency. The RIT indicator is green when RIT is active.

Another long press of the RX button disables RIT.

Similarly, a long press of the TX button in an Active Slice activates the XIT (Xmit Incremental Tuning)

feature. XIT allows the Slice Receiver’s transmit frequency to be adjusted up and down with the

tuning knob while holding the reception frequency constant. In this mode, the reception bandpass

is shown on the Panadapter as a light blue band while the transmit bandpass is shown as a light red

band. The XIT indicator is red when XIT is active. Another long press of the TX button disables XIT.

The RIT/XIT step size is dependent on the mode assigned to the slice receiver. In AM/LSB/USB/FM

modes, RIT and XIT adjustments occur on 10Hz steps. In CW/RTTY/DIGU/DIGL modes, RIT/XIT

adjustments occur on 5Hz steps.

The Use VFO B Knob for VFO A RIT/XIT button on the Maestro tab of the Main Menu (see section

33.2, Maestro Tab) controls the details of RIT/XIT operation. When the option is not selected, the

VFO A and VFO B controls operate independently as described above. When the option is selected,

and when Slice B is not active (RX button is off), then adjusting the Slice B Tuning knob will move

the Slice A transmit or receive frequency while holding the other constant. Adjusting the Slice A

Tuning knob moves both frequencies while holding the difference between them constant. When

in RIT mode, pressing the VFO B knob resets the received frequency to the transmit frequency.

Similarly, when in XIT mode, pressing the VFO B knob resets the transmit frequency to the received

frequency.

The A>B button copies the settings of the A Slice to the B Slice. If no B Slice exists when the button

is pressed, a B Slice is created in the same mode as the A Slice but at a higher frequency

determined by the mode. In AM and FM modes, the new slice is located 10 KHz higher, in sideband

modes, it is 5 KHz higher, in CW and RTTY modes, it is 1 KHz higher and in DIGU mode it is 500 Hz

higher. If a B Slice exists when the button is pressed, its frequency is set to the same value as the A

Slice, but its mode does not change. A second short press of the button causes the frequency of

Slice B to be set to Slice A. On the display, Slice B will cover Slice A until one of the slices is moved.

If two panadapters are displayed, and Slice A is in one while Slice B is in the other, then a short

press of the A>B button will change the frequency of Slice B to that of Slice A.

A long press of the A>B button (A>>B) activates the constant frequency difference feature. The A

and B Slices are locked together so that a change to the frequency of one of them changes the

other by the same amount in the same direction. The difference in the frequencies remains

constant. Another long press of this button disables this feature. The two Slices do not have to be

located in the same panadapter, or on the same band.
