I was footling about on one of the Moose servers with some Python and MySQL code and couldn’t get it to work properly. I knew there was a similar piece of code that I used to generate maps of chaser locations. So having got that working I was able to fix the bug in the new code. I hadn’t mapped anything for a long time and as I now had the mapper routines running I thought I’d update some maps.
Mike 2E0YYY is a good data source because he spends long enough on a summit to rack up a few QSOs and that helps generate more blobs on the map. So taking only Mike’s activations in March 2012 where he had more than 50 QSOs as the starting point I’ve generated some new maps. As before red markers are 2m-FM and blue markers are 2m-SSB. Green marker is the summit. For a marker to appear you had to be in the 2009 callbook and not “details witheld”. /M and /P contacts are not mapped. Hover on a marker to get the callsign.
What does it mean? Well it probably says something about the take off from these summits. The one which is most interesting to me is for nw-031. It’s got the chaser pattern I’d have expected. But I’d not have expected the Ynys Mon QSOs, probably some knife edge diffraction over Snowdon or the Glyders.
