- # 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.

- # 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
# process to just the standard "message passing" which has been shown to be able to sustain over 5000
