By default, the HOME display always appears first when JAGUAR is started. In addition, JAGUAR PRO offers extended spectrum displays (HISTORY) which contain the "offset history" produced by SCANS (see LIVESCAN and FILESCAN for more details).
The overview HISTORY display can compress 24 hours to the single display
but the detailed HISTORY displays can be very long (think about 24 hours of data, one line generated at every 10th second):
If there is no offset history (scan data) available, you will see just empty time frames. You can start FILESCAN (see FILESCAN) to run a short scan to see how the offset history data is displayed on the HISTORY screen.
These extended HISTORY views can be used to analyze the offset history throughout the day, revealing sign-on/sign-off times, and jump directly to the time spots where an interesting rising carrier levels are being observed. The normal point-and-shoot option is available: when the mouse cursor is bright, there is a recording available behind that spot, and clicking there brings you to that offset/time.
You can repeat FILESCAN as many times as necessary to achieve a higher resolution or scan for various time slots of the day. Earlier scan results are always replaced by the latest run for each scanned frequency. However, if you are interested in the offset history, it is highly recommended that you use LIVESCAN, which is "scanning made easy": everything is ready when you need the offsets, no need to wait long scan jobs to complete. However, you can always run FILESCAN afterwards using a higher resolution for those interesting times/frequencies seen in LIVESCAN results.
HISTORY can be opened by
You can move the spectrum location up/down on the screen by dragging the mouse. If you define SETTINGS > PLUGINS > DRAGGER=Y, you can also move the spectrum location left/right on the screen by dragging the mouse. Right-clicking the mouse restores the center location if you have relocated the position (if not, then the mouse right-click performs the standard user-defined right-click operation).
You can change the spectrum width (range) between 0.025 kHz and 50 kHz by clicking/scrolling the SLIDER > ZOOM.
When you place the mouse over a spectrum screen, you can move the spectrum location up/down on the screen by scrolling the mouse wheel.
SLIDER has two important controls for customizing spectrum displays: STYLE (GLOW > XRAY > CATWALK) and CONTRAST (spectrum color strength). See SLIDER for more details.
In today's MW DXing eyes are as important as ears, so the visual help given by HISTORY displays can save a lot of time when studying a huge number of recordings.
