[CQ-Contest] Contest simulation using RBN archives

[Jukka Klemola]

Big energy, wide bandwidth noise sources are not in RBN data.
They will have some effect in evaluating the results with RBN + solardata +
logs.

For SSB contests, you can use RBN data there is; beacons, non-contest
CW+RTTY; in addition to logs alone.


I think there is a cool possibility for next level propagation analysis
that potentially leads to development in propagation predictions.


In case you have database skills for this .. please keep on doing !
