Just out of curiosity, I had a look at the number of CW spots on the DX cluster for the various Wild Atlantic Way stations... EI11WAW to EI99WAW. It's probably fair to say that the more active a station is on cw then the more cw spots should appear on the DX-Cluster.
This was the standings on the 16th of February 2017 and it shows all the cw spots since the start of the year. As you can see above, EI77WAW has the most spots and this call has been very active on cw on the bands from 80m to 17m.
What's also obvious are the rare ones....EI11WAW and EI88WAW....with just 17 and 18 spots respectively.
