It must be my age! My XYL said last Tuesday "have you got a contest tonight?" I said, "no" thinking it was the end of November. Somehow I also read my email reminder of the 70cm UKAC too late last night. So, I managed to miss both the 2m and 70cm December legs of the monthly RSGB activity contests, thinking it was the end of November still!
Incidentally, my article on the big-wheel antenna for 2m is in the January RadCom. If I had remembered, this is the antenna I would have used! It works well and is a horizontal omni with gain. Mine was very kindly erected by David G0LRD, to whom I am much indebted.
