There's a little more than this to the whole problem, but, in general,
if what you want to do is measure the distance to the moon, a radar
built with an oven magnetron probably isn't the best way to go about
doing it.


Nobody asked me, but fooling around with oven magnetrons is potentially life
threatening, since they are properly shielded only when installed as
designed. What's cookin' might be _you_!

Most in this group know that, so I'm throwing out the caution for the
possible newbie. (There was a rumor years ago about a guy who damaged his
internal organs trying to use a magnetron as the LO for a homebrew TVRO
satellite downconverter. I looked hard and could not find any
sustantiation.)
