Specifying Start and End Times for Each Band
If you check the Band Filter window's Enable Start/End & Max Origin DX Filtering box, then you can optionally specify the following additional filtering rules for each band individually:
- a starting and ending UTC time (either an absolute time, or as an offset in minutes from the current Sunrise or Sunset time)
When you specify a band's Start UTC or End UTC settings, Spot Database Entries whose frequencies are in this band will only be visible when the current UTC time is after the Start UTC and before the End UTC specified for that band. To temporarily disable Start/End UTC filtering for all bands, check the Ignore panel's Start & End times box.
You can only modify a band's starting UTC time or ending UTC time if that band's Enable box is unchecked. Typically, one would
uncheck a band's Enable box
specify or update the band's Start UTC and/or End UTC settings
check the band's Enable box to put those settings into action.
To specify an absolute UTC time, simply type that time; for example, if you want to filter out spot database entries that occur on 80m before 0900Z, then type 0900 into the 80m band's Start UTC textbox. To specify a UTC time relative to sunrise or sunset, use the format SR+X, SR-X, SS+X, or SS-X, where
SR refers to the current sunrise time
SS refers to the current sunset time
X is an offset in minutes.
To filter Spot Database Entries that occur on 160m starting 45 minutes after sunrise, for example, type SR+45 into the 160m band's End UTC textbox.
You can manually specify or modify the current sunrise and sunset times in the Band Filter window's Sunrise & Sunset panel; to do this,
check the Ignore panel's Start & End times box
specify or modify the Sunrise UTC or Sunset UTC textboxes
uncheck the Ignore panel's Start & End times box
If you are running DXView version 2.8.9 or later, the Sunrise UTC or Sunset UTC textboxes will be automatically updated at 0Z each day, eliminating the need to manually keep these settings up to date.
