Heard the KP4AO gang for about 1.5 hrs today starting 1800z here. CW 
432.043.8 
Using single 30 element yagi, elevated. Did not make a QSO however. 

This is the first EME signal I have ever heard! YAY!  Would be easier if I 
could actually see the moon! Was out in back yard with protractor and 
compass.... 

They were very weak. Not as advertised....wonder if they are really running 
400 watts? Anyone know?
