One rig used the elecraft 500w amp and one used a 1.5kw amp.  The two elecrafts could not operate on the same band at all.  Maybe it was something with the setup.

Your expectations are unreasonable -- 20 ft is WAY too close, even for 
two great rigs on the same band at 500W.  We run K3s to KPA500s on the 
same band for CQP (Cal QSO Party) county expeditions and use 250 ft 
spacing with antennas carefully located to be essentially colinear. 150 
ft is not enough.
