Discarding Incoming Spots by Band, Mode Family, Spotting Station Location, or Spotted Station Location

SpotCollector Online Help Contents

 

The checkboxes and selectors on SpotCollector's Pre-filtering window control its ability to discard certain incoming spots without adding them to its Spot Database. This can be used to eliminate CPU time and memory consumed when processing spots of active stations in which you have no interest, e.g. on a band for which you have no antenna, or using a mode family that you do not employ. Pre-filtering can be helpful in reducing the computational load from high-volume spot sources - like DX Cluster configured to convey spots from RBN Skimmers. However, Spot Database Entries populated by spots of nearby active stations not needed for awards can be used to identity propagation openings with stations with whom a confirmed QSO would advance your award progress; thus pre-filtering should be used carefully, and often episodically.

 

Pre-filtering settings

Enable when checked, the "discard" options are active; when not checked, no incoming spots are discarded, no matter how the "discard" options are set
Pre-filter Skimmer spots only when checked, settings in the "Discard incoming spots ..." panels only apply to spots submitted by stations whose callsigns end in -#
Discard incoming spots of NCDXF beacons when checked, NCDXF beacons spotted within 200 Hz of an NCDXF beacon frequency are discarded
Discard spots from spotting station callsigns ending in -# when checked, spots submitted by stations whose callsigns end in -# are discarded; this suffix is used to identify spots submitted by an RBN Skimmer
Discard spots from spotting station callsigns ending in -@ when checked, spots submitted by stations whose callsigns end in -@ are discarded; this suffix is used to identify spots submitted from the DX Summit web cluster
Discard incoming spots on selected band panel checking a band's box in this panel will cause spots on that band to be discarded
Discard incoming spot in selected mode families panel checking a mode family's in this panel will cause spots in that mode family to be discarded
Discard incoming spots from stations in selected continents panel checking a continent's box in this panel will cause spots submitted by a station on that continent to be discarded
Discard incoming spots of stations in selected continents panel checking a continent's box in this panel will cause spots of stations on that continent to be discarded
Discard incoming spots of stations in selected DXCC entities panel setting one of this panel's selectors to a DXCC entity's prefix will cause spots of stations in that entity to be discarded; clicking the Clear button beneath a selector clear's that selector

Determining if Pre-filtering is Enabled and Active

If in SpotCollector's Pre-filtering window, the Enable box is checked, and pre-filtering governed by at least one checkbox or selector is enabled, then
