I figured out why my EME setup was not working. After fixing the antennas, by mistake I fed them out of phase. Instead of getting 1+1=2 I got 1-1=0. I still made one EME QSO when the antenna was off, because out of phase the antenna has peaks about 20 degrees off.
After fixing the phasing, NH6V copied me at -20db but I could not copy him. Most likely my preamp is blown up in a special way: When damaged, PHEMT devices still have the same gain but their noise figure can jump 10db+.
