Phil, I'm using a 229b tuner with a current forcing balun and open wire 
feeders, 
at 20w output I can adjust the tuner  for a 1:1 swr.

Wayne....

Put the 20 m antenna, not the dummy load on the rig.  Then look at the 
output SWR on 20 when the power is low.  Let me know whether the SWR is 
normal or high.
