Matt,

That would be great.  I'm free today, week day evenings, and then Friday
through Sunday next week.  What works best for you?

Juan

Juan,

I live in Mountain View, about 125 miles from the base.  If you would
like, we could get together to try to record the radar with some USRP
equipment, which will allow 8 or 16 MHz of RF bandwidth.  This would
allow us to get detailed pulse profiles and other statistics on the signal.
