Hi,

Could you please help me understand the meaning of the highlight circles, around some calls in the Map F1 in Telnet Cluster?
At this moment I have 13 circles.

73 Manuel Fernando CT1BXX

Circles are RECENT spot (< 5 minutes from last spot heard)
Orange circles represent spot highlighted by your selection in the search area (e.g. IOTA filters)
