11 HOW TO OPERATE A SLICE RECEIVER

11.1 HOW TO CREATE AND DELETE A SLICE RECEIVER

Maestro can control two Slice Receivers labeled A and B. The first two columns of knobs and

buttons on the Maestro front panel control the A Slice, and the second two columns control the B

Slice. When the A Slice Receiver is operating, the A RX button will be illuminated green. When the

B Slice Receiver is operating the B RX button will be illuminated green. Press the RX buttons to turn

the A and B Slice Receivers on and off.

Pressing the A or B RX button will place a Slice Receiver inside the corresponding Panadapter. A

Slice Receiver will be created in the center of the Panadapter if none exists. If a Slice Receiver is

already present in the Panadapter, the new Slice Receiver will be created with the same basic

characteristics (mode, DSP settings, etc.) as the active Slice Receiver, or with the characteristics of

the Slice Receiver closest to the center of the Panadapter. Please see section 12.2, How to Create /

Delete a Slice Receiver in the Second Panadapter for an explanation of how Slice Receivers are

created when a second Panadapter is open.

The various models of the Signature Series transceivers support different numbers of Slice

Receivers, varying from two to eight. The Maestro supports a fixed number of two Slice Receivers.

When a Slice Receiver is active, pressing its RX button will deactivate it and remove it from the

Panadapter display. It is possible to disable both Slice Receivers so that only the panafall display

remains. With no Slice Receivers, no signals will be audible from Maestro or the radio.

Note: If the removed Slice Receiver was enabled for transmission, the radio will be unable to

transmit until another Slice Receiver is selected for transmission.

If a Slice has moved off-screen outside the bounds of a Panadapter, the Slice Receiver display will

change to indicate where the Slice is tuned relative to the Panadapter. Double tapping

on the indicator will center the Slice in the Panadapter display. The indicator also will show

if the transmitter is enabled in the off-screen Slice.

An off-screen Slice can be closed by pressing its RX button to disable it.

If a Slice Receiver moves too far beyond the bounds of the Panadapter, it will be put into a

detached state and will no longer produce audio. Moving the Slice back into the bounds of the

Panadapter will put the Slice Receiver back into a normal state which produces audio. The bounds

of the Panadapter are determined by the radio hardware and vary by radio model.

11.2 HOW TO TUNE A SLICE RECEIVER

Knob Tuning: Use the front panel tuning knobs to adjust the frequency of the A Slice Receiver

(larger knob) or the B Slice Receiver (smaller knob). The knobs are weighted and spin freely to

provide rapid tuning. Each full revolution of a knob creates 64 pulses each of which maps to one

step change in frequency, up or down. Turning the knob quickly enables acceleration to traverse

more of the band faster. The size of the steps, in Hertz, is controlled by the A and B Step buttons.

See section 36.2, Slice Receiver Tuning Knobs and Buttons for full details.
