I've been manually collecting data on the number of QSO from H44WA.
There are two curves here. The first, (green/blue) is the 3rd order fit. The second (red) is the L.R. (Linear Regression fit, y=mx+b).
Of course the rates will not stick to this -- there are too many other factors -- solar qualities, band conditions, etc... And, there is CQ WW Contest while they are on island.. That should be a boost!
