Thanks Pat.
I am still trying various combinations of filtering and tuning off
frequency. I think I heard a couple of meteors though they were not
prominent. Although I get the radar tone strong I am wondering if I need
better antenna gain to get actual meteor reflections? I am using an old
tv antenna but I think other folks might be using multi element yagis
that are made for 220 MHz. Not sure about this.
In my research I found a very fine radio meteor page that gives info on
the Space Surveillance Radar at :

I will update further if I come across more information.
