I specifically DO NOT want to generate a large volume of rows. Filtering by a single callsign would be a great way to go. I'm basically after spot data: date, time, frequency, mode, callsigns, and grids. Plus distance, bearing, and other derived data that's available.
I'm trying to monitor spots over an extended period of time. I could monitor a series of 24-hour results. But I've elsewhere learned the hard way that if my database access malfunctions I may not discover the problem until after the data has become available. So I then end up with a hole in my data and have to restart the entire monitoring project. Big ouch!
So the idea is, Accessing a week or a month of data would avoid the problems of failed or forgotten daily access.
To be frank, I'm not immediately sure what I'm doing. I'll have to get my hands on data to be able to think up some study hypotheses and the appropriate statistical treatments. For what it's worth, I'm a PhD-level, trained researcher and computer science professor at a small, private university. But I haven't previously done any work at all in this area. All that means nothing more than that I SHOULD know, or be able to figure out, what it is that I'm doing. The big picture is that, ideally, I'd like to create one or more publishable studies. But there are many other demands on my time and this sort of research is not nearly my top priority.
If I should be lucky enough to actually manage to create anything credible, I'd be happy to run any submitted manuscripts by you and to offer you full co-authorship, in view of your work in having created and provided access to the database. Since the authors of a paper are listed alphabetically by last name, I only wish that G, for Gladstone, were alphabetically later than M, for McCarty. Would you consider changing your last name to something alphabetically later? jk :-)
Cheers,
