hi all,
didn't realize i wouldn't get emails for your followup msgs - hence my delay. thanks for all the info!
here's the radar plot for 30':

and 40', though i think it's not applicable to me:

btw, i compared these side by side, also to my original 20' plot, and the differences seemed to me to be small - but are they still significant?
if i understand what y'all are saying about the virtual channel numbers, it means that for example, 9.1, 9.2, and 9.3 could be being transmitted from different transmitters. if that's the case, then why aren't they included separately in the radar plots? oh, and i realized it's KQED digital 9.2 that i am having trouble with, rather than 9.3. but then, neither shows up in the radar plots.
