While K3LR usually posts the Dayton Hamvention presentations, here's N6TV's
presentation in advance.  Lots of great info!

Thanks to N6TV for letting me pass this along.

I've posted the slides from the talk I gave at the Dayton Contest Forum,
"Using the Reverse Beacon Network as a Contesting Advantage", here:


Slide 16 shows how to avoid most busted spots from the RBN.  To summarize,
connect your cluster software or contest logger to
arcluster.reversebeacon.net port 7000, then sign in with your callsign and
enter the following command to establish a filter:

set dx filter call=N6TV or (Skimmer and Unique>2 and (SpotterState=CA or
SpotterState=NV or SpotterState=UT))

Where you substitute [yourcallsign] with your own callsign (without the
brackets), so that you can still see all the Skimmers that hear *you*, e.g.
New "Unique>2" filter (only available on AR Cluster V6 nodes) means that the
spot has to be heard exactly the same way by at least *two* skimmers before
you will see it.  This works well.  Only spots from the specified states
will be shown.

SpotterCqZone is also supposed to work, but at present, it doesn't seem to.
 I've sent an email to AR Cluster author AB5K about that.  No reply yet.

Bob, N6TV
