- # We have an RBN data line, dedupe it very simply on time, ignore QRG completely.

- # the spot at the same time (velocity factor of the atmosphere and network delays
- # carefully (not) taken into account :-)
-
- # Note, there is no intelligence here, but there are clearly basic heuristics that could
- # be applied at this point that reject (more likely rewrite) the call of a busted spot that would
- # useful for a zonal hotspot requirement from the cluster node.
- # In reality, this mechanism would be incorporated within the cluster code, utilising the dxqsl database,
- # and other resources in DXSpider, thus creating a zone map for an emitted spot. This is then passed through the
- # normal "to-user" spot system (where normal spots are sent to be displayed per user) and then be
- # processed through the normal, per user, spot filtering system - like a regular spot.
+ # The main de-duping key is [call, $frequency], but we probe a bit around that frequency to find a
+ # range of concurrent frequencies that might be in play.
# The key to this is deducing the true callsign by "majority voting" (the greater the number of spotters
# the more effective this is) together with some lexical analsys probably in conjuction with DXSpider
# Clearly this will only work in the 'mojo' branch of DXSpider where it is possible to pass off external
# data requests to ephemeral or semi resident forked processes that do any grunt work and the main
