I had the same reaction - one pixel on the radar map pretty well covers
my entire housing development ;) I do understand that the radar only has
so much resolution, natively, and I'm still very happy to have seen the
increase in availability of radar products over the last few years. What
I'd really like to be able to do, though, is get just the radar returns
- no "map" lines or place names. I think that I could probably archive
a copy of the radar output during a time when there were no returns,
and arrange a script that would subtract that from the active radar,
but I haven't played with it yet. I suppose before I do that I should
ask the list whether anyone else has solved that particular annoyance yet?

BTW, did you download the geo files that have the radar images, or the
ones with the radar estimated precipitation? I had the latter at first,
and only found the conventional radar ones by accident. And of course
there are lots of other NWS products available if you want to wander
around their server.
