FLEX-6000 Signature Series – Maestro User Guide

Drag Tuning: Drag Tuning is one of the more common tuning methods. By touching the Receive

Filter (lighter blue area of the Slice Receiver) or the carrier (the vertical yellow or red line of the

Slice Receiver), and moving your finger left or right, the Slice will move up or down in frequency

while the Panadapter remains stationary. This tuning occurs in increments of the currently selected

step size. Once the Slice reaches the edge of the Panadapter the Slice will stop and the Panadapter

will begin to move behind the Slice. This is called Pan Edge Tuning and allows rapid tuning above or

below the Panadapter’s current frequency range.

Tap Tuning: Double tapping anywhere in the Panadapter grid will initiate a Tap Tune. Tap Tune will

move the Active Slice to the frequency where the tap occurred. The Active Slice is designated by a

yellow carrier line and a yellow triangle at the top of the carrier line (see section 11.3, Making a

Slice Receiver Active).

Direct Frequency Entry: Direct Frequency entry for any Slice Receiver is a tuning option. Simply tap

on the Slice Receiver’s frequency display to open the Slice Receiver Menu and use the ten-digit

touchpad to enter the frequency in megahertz using a single separator specific to your country (for

the US it is a period, for other countries, it may be a comma). For example, entering “14.0705” will

tune to 14.070.500. You can also enter some frequency ranges using kilohertz, but the data

entered is limited to 4 or 5 digits and you cannot use a country-specific separator. For example,

entering “7250” will tune the Slice Receiver to 7.250.000 megahertz.

Tune Step Size: The tuning knobs generate 64 pulses per revolution. The amount of frequency

change caused by one pulse from a tuning knob or by dragging the Slice Receiver is determined by

the Active Slice Tune Step Size. Tune Step Size is mode-specific and can be set with the A or B Slice

Step Button. A single press of the button increases the step size by an amount appropriate to the

Slice Receiver’s mode. The new value is shown in a pop-up display. A longer press of the button

decreases the step similarly.

11.3 MAKING A SLICE RECEIVER ACTIVE

A Slice Receiver consists of a center Carrier Frequency displayed by a solid yellow or red

vertical bar. A yellow bar indicates the Slice is “Active,” indicating that this is the Slice that you are

currently manipulating. Moving the A or B Tuning knob makes the corresponding Slice Receiver

active. Tapping a Slice Receiver’s receive filter display makes that Slice active. When a new Slice

Receiver is selected as the Active Slice, the old Active Slice will become inactive and its carrier line

will change to red. There can only be one Slice active at a time.
