I will go to Tucson tomorrow, in advance of the ScienceCity science fair on the University of Arizona campus on Saturday and Sunday. I will take a roundabout way to Tucson, and I am planning a stop on the DM52ax/DM53aa grid boundary in southeastern Arizona. I am planning to work the two AO-91 passes around 1820 and 2000 UTC, before driving on to Tucson. I have operated from this location many times before over the past several years, parked along US-70 near Safford AZ in Graham County. I do not plan on staying for additional passes, as I still have a drive of over two hours to get from that spot to Tucson, and a busy weekend ahead of me.
QSOs will be uploaded to Logbook of the World at some point, either tomorrow night when I am in Tucson, or possibly early next week after I am back home. Hope to work a bunch of you who may need either or both of these rarely-heard grids.
