I had the same situation and discovered an article in QST years ago that
the problem was poor directivity of the SWR bridge (discrimination to power
coming from the reverse direction). I found that the Drake W4 had better
directivity than a Bird but poorer corrolation to power output from 1.8 to
30 MHz. Seems you can't have it both ways....
