[Skimmertalk] Trends in RBN Activity

Recently a friend suggested that FT8 was probably making a dent in
activity on the RBN and taking away from CW in general. Out of
curiosity, I compared last week on the RBN (weekdays only, to avoid
contest activity) with the corresponding week in 2016, and was pleased
to see that the volume of RBN spots in 2017 was up about 8.4 percent
compared to the corresponding week in 2016.
Maybe growth would have been stronger if FT8 and WSPR had not been
introduced, but for amature system near the bottom of the sunspot cycle
I think the continued upward trend is encouraging. The same week in 2016
was down 12.1 percent compared to 2015, which looks more like what I
would have expected this year.
Looking ahead to the big DX contest weekends, Felipe made a change in
the data flow at our server this week to sharply reduce the number of
operations that need to take place after spots are received from RBN
nodes and before each individual spot is sent out. We are hopeful this
will improve the server's reliability and handling of large volumes of
spots, as well as reducing the delay in their being posted on retail
servers around the world.
Feedback would be appreciated. ARRL CW Sweepstakes will probably be the
first major test.
