[Laser] Wanted Laser's for VUCC Attempt

[Zack Widup]

I wish I had the time! I've been spending all my spare time for over a
month working on a 47 GHz transverter.
:-(

I'm fortunate (sometimes) to be in relatively flat farmland. There are a
few hills, my favorite being the highest point in the area in EN50rl, close
to 1000 ft above sea level. The one in EM59xx is at about 850 feet. The
only problems come when you want to operate on the edge or in the middle of
a corn field when the corn is close to 7 feet tall and you don't have a way
to get up above it.
