[CQ-Contest] [sysops] RBN Announcement on FT8 Spotting

The RBN applies the same standard to FT8 as to CW and RTTY - only CQ 
(equivalent) spots and only re-spotting once every 10 minutes on a given 
dial frequency.  However, as our first tests indicate, there is still a 
lot of FT8 traffic.  This *is* an experiment.

73, Pete N4ZR
Check out the Reverse Beacon Network
at <http://reversebeacon.net>, now
spotting RTTY activity worldwide.
For spots, please use your favorite
"retail" DX cluster.
